Description

Bristle tuft, brush roller having bristle tuft, and method for disassembling brush roller

Technical Field

The present disclosure generally relates to a process for forming a three-dimensional texture on a board surface, and more particularly to forming a three-dimensional wood grain texture on a board surface.

The invention belongs to the field of flooring, in particular to the field of printed flooring with three-dimensional wood grain texture on the surface, and more particularly relates to a bristle cluster, a brush roller with the bristle cluster, and a method for disassembling the brush roller.

Background Art

Wood-grained floors are widely used in interior decoration due to their higher ornamental value and softer tones. However, solid wood floors are expensive, which limits the breadth of their market. Based on this, a floor with a three-dimensional texture imitating wood grain is widely manufactured and sold, such as a wood-plastic floor with a three-dimensional wood grain on the surface. In a known method for producing a three-dimensional wood-grained wood-plastic floor, the steps are as follows:

S1. The basic decorative wood grain pattern is printed onto the wood-plastic panel in the first printing step to form a pattern plate;

S2. The curable substance is evenly coated on the pattern plate; this step can be performed multiple times to form a first plate to be cured;

S3. The board to be cured is transferred to a digital printing workstation, and a digital printer set in the digital printing workstation prints the inhibitor on the board to be cured according to the wood grain coordinate information known in the first printing step, so that the inhibitor is aligned with the wood grain to form a second board to be cured;

S4. The second plate to be cured is subjected to a curing process, such as a light curing process;

S5. Simultaneously remove the polymerization inhibitor and part of the incompletely cured curable material to form a three-dimensional wood grain board.

Inhibitors are generally non-curable substances. The ways in which inhibitors form texture patterns on the surface of curable substances mainly include the following:

a. The polymerization inhibitor drips onto the curable material, occupying part of the original position of the curable material. Since the polymerization inhibitor itself does not cure, it can be removed after the curing process, leaving a dent in the position originally occupied by the curable material;

b. The polymerization inhibitor drips onto the curable material and forms a mixture with part of the curable material below. The curing speed of the mixture is slower than that of the original curable material. It is not completely cured during the curing process, so it can be removed after the curing process, leaving a dent at its original position;

c. The polymerization inhibitor drips onto the curable material, which has the effect of hindering the curing process of the curable material below, for example, blocking or preventing the light from contacting the curable material during the light curing process. The blocked part of the curable material cures more slowly and is not completely cured during the curing process, so it can be removed after the curing process, leaving a dent at its original position;

In methods b and c, the mixture formed by the inhibitor and part of the curable material below it, or the curable material blocked by the inhibitor, is called a slow-solidifying substance. The slow-solidifying substance has a slower curing speed than the curable material, so that when the curable material is completely cured, the slow-solidifying substance is still not completely cured and can be physically removed. There are many means for removing the slow-solidifying substance, such as using high-speed fluid flushing to remove it. However, the surface structure obtained by this type of method has smooth edges and is quite different from the naturally formed wood grain structure. In another method, a roughened texture is set on at least a portion of the surface structure by using one or more (rotating) brush rollers. In the process of removing the slow-solidifying substance, the surface structure is caused to have an undulating profile that is closer to the appearance and feel of natural wood grain, and typically has sharp edges (indistinguishable, discontinuous edges) instead of conventional smooth, rounded edges (which are typically achieved by high-speed fluid flushing), which improves the visual appearance and/or tactile (tactile) properties of the surface structure. This type of brush roller is typically used in many processes of plate surface treatment, such as the steel wire roller described in CN112264894A and the wire drawing roller described in CN112589639B. Its typical feature is that the bristles are arranged on the surface of the roller along the radial direction of the roller body, and the distance between the roller body axis and the plate surface is slightly smaller than the distance between the bristle head section and the roller body axis, so that the bristle head section can partially penetrate into the plate and take away some of the material on the surface of the plate. The material can be part of the plate itself, or an embossed material formed after pretreatment on the plate (typically a wood grain structure formed by slow solidification).

In particular, the slow-acting substance has a sticky property. When the slow-acting substance is removed using an existing brush roller used for processing surfaces such as wood, metal, and ceramics, the slow-acting substance cannot be quickly removed like substances such as material debris, but often remains on the bristle head section to form residues. The residues cannot be removed by the rotation of the brush roller or the suction device, which causes the bristle head section on the brush roller covered with the residues to be hidden, thereby limiting subsequent use.

In the prior art, the bristles used on the brush roller are mostly in a straight line configuration, which leads to the bristles being more inclined to be arranged in clusters. After adhering to the slow solid, the clustered bristles will inevitably stick together, losing the function of drawing to form three-dimensional wood grain during the production process of the wood plastic floor. To restore the function, the bristles need to be cleaned, that is, the brush roller needs to be disassembled from the production line as a whole, which will reduce production efficiency.

In addition, KR1020090086739A shows a straight-line bristle structure set on the roller body, using a mounting groove set on the surface of the roller body to clamp the root section of the bristle inward to disperse the head section. It can be foreseen that the application in the production process of three-dimensional wood-grain wood-plastic flooring will reduce the tendency of adhesion to the slow-solidifying agent. However, in this setting, the degree of bristle aggregation in the middle is much greater than that on both sides, and this aggregation phenomenon is more intensive than the method of directly setting on the roller body, so that when directly applied to the above-mentioned three-dimensional wood-grain wood-plastic flooring production method, the slow-solidifying agent more tightly bonds the multiple bristle head sections in the middle together, causing the local bristles to directly fail during the production process, which will result in the need to disassemble and clean the entire brush roller even if the other parts of the bristles still have the ability to draw wires during the production process.

Summary of the invention

One of the objects of the present invention is to provide a bristle tuft having properties which reduce the risk of the head sections of the bristles being stuck together by slow solid residues.

A second object of the present invention is to provide a brush roller that can be quickly disassembled from an assembly line, thereby reducing assembly line downtime and improving production efficiency.

A third object of the present invention is to provide a brush roller equipped with the bristle tufts.

A fourth object of the present invention is to provide a method for disassembling the brush roller.

A fifth object of the present invention is to provide a method for preparing a surface structure using the above-mentioned brush roller.

The technical solution adopted by the present invention to solve the above problem is: a brush bristle cluster for removing uncured resin on the surface of a substrate, comprising:

A plurality of bristles gathered into a cluster, wherein at least one bristle comprises:

A general root section for installation on a roller body, a general head section extending in a direction perpendicular to the rotation axis of the roller body, and a spacing section arranged between the general root section and the general head section and used to separate at least one bristle adjacent to the bristle to form a state in which the two are separated except for the general root section, and the spacing section has a spacing structure.

In the present application, the general root segment, the general head segment and the spacing segment constitute the bristles, wherein:

Generally, the root section is located on the side of the bristles facing the roller body and has an end for fixing on the roller body.

General head section: located on the side of the bristles away from the roller body, and has an end facing outward and serves the function of drawing and removing impurities from the bristles.

Interval segment: located between the general root segment and the general head segment.

The existence of the interval section can separate the bristles, which will drive the bristles to have the ability to repel the adhered solids. Even when the bristles are installed on the surface of the roller body through the groove body, the phenomenon of the bristles gathering in the middle will be greatly reduced due to the existence of the interval section.

The spacing structure can be formed by a structural transformation of the bristle body, which leads to lower manufacturing costs.

A further preferred technical solution is that the bristles are made of metal.

Metal has better shape-changing properties and is hard enough to support the shaping process of the surface structure. On the other hand, metal can resist the wear effect from cleaning devices such as scrapers during the subsequent cleaning process, so that the bristles can retain their original shape after multiple cleanings, making them fully functional and thus maintaining their service life to the greatest extent.

A further preferred technical solution is that the spacing structure is formed by bending part or all of the bristle bodies of the spacing segments of the bristles.

The bending structure is generated by the deformation of the bristle body, through mold pressing, extrusion technology, or winding technology. The bending structure part can be similar to the shape of instant noodles, or it can be similar to the shape of a spring. In short, the bending structure is the radially outward expansion structure of the middle part brought by the bristles, and due to the material of the bristle body, this expansion structure still has a certain elasticity.

A further preferred technical solution is that the bend is a spiral bend and the spiral turns are arranged in sequence along the extension direction of the bristles.

A further preferred technical solution is that the spacing structure of the spacing segment is an enlarged portion arranged in the spacing segment, the diameter of the bristles of which is significantly larger than the diameter of the bristles of the general root segment.

Here, "obviously" means that in the eyes of ordinary people, the enlarged portion is thicker than the general root section. Functionally, the enlarged portion can separate at least one bristle from the bristles to form a state in which the two are separated.

A further preferred technical solution is that the spacing structure is a sleeve fixed on the bristle spacing section, and the sleeve is sleeved on the outside of the bristles.

A further preferred technical solution is that the maximum size of the outer contour 1 of the root segment and the head segment is 2 mm. Preferably, the outer contour 1 is 0.5-1 mm.

The size of the outer contour one refers to the diameter of the smallest circle that can accommodate the end face section of the general root segment or the general head segment.

The larger the outer contour of the bristle, the higher its rigidity, but the corresponding deformation ability is poorer, and the fineness of the wire drawing is lower. The smaller the diameter of the bristle, the finer the wire drawing and the higher the deformation ability, but the corresponding rigidity is lower, and the ability to remove slow solids in the surface structure is lower, so the size of the outer contour of the bristle should determine a reasonable range of use.

A further preferred technical solution is that the maximum dimension of the second outer contour of the spacing segment is 5 mm.

The size of the second outer contour refers to the diameter of the smallest circle that can accommodate the cross-section of the end face of the spacing segment.

A further preferred technical solution is: assuming that the total length of the bristles is X, and the straight-line distance from the end point of the root segment to the end point of the head segment is Y, then X:Y=1:1-0.8.

When the bristle body is not deformed, X:Y = 1:1. In this case, the interval section is not formed by the bristle body through its own deformation, such as a rubber sleeve or a spring sleeved on the bristle body.

The curved structure formed by the deformation of the bristle body, the X value remains unchanged while the Y value decreases. When the Y value is smaller, the curvature of the curved structure is greater, and the distance between the bristles will also be larger. When the distance between the bristles reaches a certain value, it will affect the overall density of the bristles. The density of the bristles is closely related to its ability to produce a brushed effect. When the density of the bristles is not enough to clean up the slow solids in time, it is considered to be substandard. Therefore, the ratio of X to Y should be controlled within a reasonable range.

A further preferred technical solution is that the spacing structure is a coating covering the bristle spacing section.

The coating is a substance, such as a polymer, that is applied to the bristle body to form a coating to isolate the bristles.

A brush roller, comprising:

The roller body has a cylindrical structure and a rotating shaft arranged along the axis of the cylindrical body;

Bristles are arranged on the surface of the roller;

A roller sleeve, used for rotatably mounting the rotating shaft, and provided with an external fixing member;

The suspension component is arranged above the conveyor belt in the assembly line. The suspension component is provided with a suspension groove for slidingly installing the roller sleeve along the extension direction of the rotating shaft, and an internal fixing piece is arranged in the suspension groove for fixing the external fixing piece.

After the above treatment, the bristles are slowed down to cover the general head section of the bristles with slow solids. However, in the actual production process, after working for a long time, the general head section of the bristles will still adhere to the slow solids, which will cause the brush roller to lose its wire drawing function. If the brush roller can work again, it is necessary to disassemble the brush roller from the assembly line, and clean the slow solids adhered to the head section of the bristles in time. However, the assembly line has to be stopped during the disassembly process, that is, the disassembly time directly affects the production efficiency of the assembly line.

The core technical concept of the brush roller quick release is to reduce the proportion of the total weight of the roller body that needs to be borne by the fixing components in the suspension part used to directly fix the roller body, such as internal fixing parts; and increase the proportion of the total weight of the roller body that needs to be borne by the fixing components that do not directly fix the roller body, such as suspension grooves or other clamping structures; because it is understandable that the time to remove the roller body from the indirect fixing component is much less than the time to remove it from the direct fixing component.

Based on this, in the present invention, the component used to fix and bear most of the weight of the roller body is the suspension groove, and the direct fixing system formed by the inner and outer fixing parts is set as an auxiliary suspension groove. After the roller body is slidably installed on the suspension groove through the roller sleeve, the roller sleeve is fixed on the suspension groove through the inner and outer fixing parts. When disassembling later, only a very small number of inner and outer fixing parts need to be disassembled, and the roller sleeve can be easily disassembled from the suspension groove by sliding in the opposite direction.

A further preferred technical solution is that the slotting direction of the suspension slot is perpendicular or substantially perpendicular to the running direction of the conveyor belt.

The "grooving direction" refers to the extending direction of the longer side of the suspension groove, which is the same as the extending direction of the roller rotation axis. "Substantially perpendicular" means that the grooving direction of the suspension groove is completely perpendicular to the conveyor belt when observed by existing measurement methods, or is considered to be perpendicular based on the observation of technicians in this field, but not completely perpendicular in the mathematical sense.

When disassembling the roller body, it is necessary to consider whether the roller body can be transported as soon as possible after disassembly. When the grooving direction of the suspension groove is basically perpendicular to the conveyor belt, the roller body can slide out of the suspension groove and be completely separated from the top of the conveyor belt, so that it can be transported in time by a transfer vehicle, forklift or other transfer equipment set below.

A further preferred technical solution is that: the suspension groove includes a main space and side spaces extending to both sides of the main space; the inner fixing member is arranged on the inner side of the suspension component and configured in the side space.

A further preferred technical solution is that: the suspension component includes a plate body for forming the suspension groove, the plate body includes an upper plate, side plates arranged at both side ends of the upper plate, and a lower plate arranged at the lower end of the side plate; the upper plate includes an upper plate side area vertically opposite to the lower plate, and an upper plate middle area located between the two upper plate side areas; the upper plate side area, the side plate and the lower plate define a side space, and the upper plate middle area defines a main space.

A further preferred technical solution is that the internal fixing member is arranged on the upper surface of the lower plate.

A further preferred technical solution is that the roller sleeve includes a roller mounting member for rotatably mounting the rotating shaft, a suspension plate for mounting the roller mounting member, and hanging ears arranged on both sides of the suspension plate; the external fixing member is arranged on the lower end surface of the hanging ear.

A further preferred technical solution is that the external fixing member and the hanging ear form a mounting profile arranged in the shape of the internal fixing member.

A further preferred technical solution is that the outer fixing member and the inner fixing member are respectively provided with fixing holes of the same specification, and are simultaneously plugged and fixed by fixing bolts.

A further preferred technical solution is that: the axis of the fixing hole is parallel to the axis of the roller body.

A further preferred technical solution is that: a fixed internal thread is provided in the fixing hole, and a fixed external thread is provided on the fixing bolt which is threadedly connected to the fixed internal thread.

A further preferred technical solution is that the external fixing member and the internal fixing member have the same or substantially the same height.

After the roller sleeve is installed on the hanging groove, the outer fixing part contacts the lower plate of the hanging groove. When the inner fixing part and the outer fixing part have substantially the same height, the inner fixing part can also contact the roller sleeve at the same time, that is, the roller sleeve is supported in all directions by the inner and outer fixing parts, realizing a clamping connection similar to building blocks. And when the outer fixing part slides on the lower plate, the roller sleeve can also slide on the inner fixing part, thus ensuring that the horizontal height of the roller body does not change during the sliding installation process, and the sliding process is smoother.

“Substantially identical” means that the internal and external fixing components are completely identical when observed using existing measurement methods, or are considered to be identical based on observations by those skilled in the art, but are not completely identical in a mathematical sense.

A further preferred technical solution is that: the end of the suspension plate close to the external fixing member is defined as the proximal end; and the roller sleeve further includes an end handrail disposed at the proximal end of the suspension plate.

The end handrail can be used to assist in pulling the roller out of the hanging groove. Since the end handrail is basically perpendicular to the direction of travel of the conveyor belt, the staff can stand on the side of the conveyor belt and pull the roller out of the hanging groove.

A further preferred technical solution is that the roller sleeve also includes a side armrest arranged on the outer side of the hanging ear.

The side handrails can assist the end handrails in pulling the roller out of the hanging groove. For example, when the roller is about to leave the hanging groove, it is unrealistic to support the longer roller by only one end. For another example, even if the roller is partially pulled out of the hanging groove and then transported, there is a moment when the side handrail is loosened and the transport device fails to fully support the roller. The above situation may cause the roller to slide unstoppably.

A further preferred technical solution is that the side armrests are grooved armrests formed by inward depression of the outer sides of the hanging ears.

After the roller sleeve is installed in the suspension groove, the side handrail is also located in the suspension groove. In some cases, the side surface of the roller sleeve fits against the suspension groove, that is, the side surface of the roller sleeve and the bottom surface of the roller sleeve participate in the role of sliding surfaces during the sliding process of the roller sleeve in the suspension groove. When the side handrail is designed to be recessed inward along the side of the roller sleeve, such as the design of a groove handrail, the side surface of the roller sleeve can be unrestricted in the process of fitting against the inner side surface of the suspension groove.

A further preferred technical solution is that: the roller sleeve also includes an auxiliary fixing piece arranged at the far end of the suspension plate; the suspension component also includes an auxiliary receiving piece arranged on the plate body and used for installing the auxiliary fixing piece.

The auxiliary fixing parts and the auxiliary supporting parts are fixed by plug-in, and their function is to assist the internal and external fixing parts. This plug-in fixing method has a fast installation speed and disassembly speed, and does not require bolt fixing. Its main function is to stabilize the other end of the roller sleeve to maintain a horizontal state without causing movement due to the rotation of the roller body.

A further preferred technical solution is that the auxiliary fixing member is located on the side opposite to the external fixing member.

“Opposite side” refers to being located on different opposite sides. For example, if the outer fixing member is arranged at the left end of the roller sleeve, then the auxiliary fixing member is arranged at the right end of the roller sleeve.

A further preferred technical solution is that: a power piece is further provided at the distal end of the roller body; and the power piece provides rotational power to the roller body via a transmission piece connected to a power device.

A further preferred technical solution is that the transmission member is a transmission belt.

The power piece is a component that provides power to the roller body, such as a wheel that can be installed with a transmission belt. A rotor motor is set at the other end of the transmission belt to drive the roller body to rotate. When disassembling, it is only necessary to remove the transmission belt from the power piece.

The outer fixing member is oriented substantially perpendicular to the traveling direction of the conveyor belt.

The direction of the external fixing is defined as the direction of the operable end of the external fixing, such as the extension direction of the rod of the bolt structure, or the extension direction of the hole of the internal threaded hole, etc. This design allows the workers to stand on the side of the conveyor belt when installing or removing the internal and external fixings, which avoids interference with the conveyor belt structure during operation to the greatest extent, and can even remove/install the conveyor belt without stopping the operation.

A further preferred technical solution is that the width of the guide groove is less than 20 mm.

A further preferred technical solution is that a bristle space is provided between adjacent guide groove bodies, and the width of the bristle space is 1-20 mm.

A further preferred technical solution is that the groove wall thickness of the guide groove body is 1-10 mm.

A method for disassembling a brush roller comprises the following steps:

S01. Remove the locking device between the inner and outer fixing members;

S02. Pull the roller sleeve out of the hanging groove.

Wherein, step S02 includes:

S02-1. Pull the roller sleeve partially out of the hanging groove, and use a transfer device to support the protruding portion of the roller sleeve from the hanging groove;

S02-2. Continue to pull the roller sleeves until all roller sleeves are disengaged from the hanging grooves and completely enter the transfer device.

A further preferred technical solution is that the transfer device is provided with a supporting device for supporting the roller sleeve, and the supporting device has substantially the same height as the suspension component.

A method for preparing a surface structure, wherein the surface structure is arranged on the surface of a substrate, comprising the following steps:

S11. The brush roller is installed above the conveyor belt, the running direction of the brush roller is perpendicular to the rotation axis of the brush roller, and the distance between the brush roller and the conveyor belt is greater than the thickness of the substrate;

S12. Such that at least a portion of the surface of the substrate is covered with at least one layer of primer;

S13. The at least one layer of the substrate is applied to at least a portion of the surface of the inhibitor, so that at least a portion of the substrate mixed with the inhibitor or at least a portion of the substrate covered by the inhibitor forms a slow solid;

S14. polymerizing the base agent and the slow solid;

S15. The substrate is conveyed to the bottom of the brush roller via a conveyor belt, and the solid matter is removed by using the brush bristles.

The polymerization inhibitor should have the effect of inhibiting the polymerization of the base agent, that is, under the same polymerization conditions, the polymerization efficiency of the base agent mixed with the polymerization inhibitor (i.e., slow solid) is slower than that of the base agent itself. That is, the partial area of the base agent where the polymerization inhibitor exists is mechanically weakened.

There are many options for inhibitors, such as water, surface tension modifiers, acrylate derivatives, etc.

The bristles should not have a scraping effect on the completely polymerized base, but only scrape off the slow-solidifying substance.

In summary, the bristles of the present invention are beneficial in that:

1. The present invention reduces the adhesion strength of the slow solid residue on the head section of the bristles and reduces the coverage of the head section of the bristles by the slow solid by arranging a spacing structure on the bristles that has the function of separating the parts of the bristles other than the general root section.

2. The present invention also provides a roller body, the surface of which is provided with a guide groove body capable of installing bristles, so that there are bristle spaces between the bristles arranged on the roller body, further reducing the tendency of slow solids to adhere to the bristles.

In summary, the benefits of the brush roller in the present invention are:

1. The roller sleeve of the rotatable roller body is fixed by using fixing parts and hanging grooves, which shortens the installation and disassembly time;

2. The fixing parts only play the role of limiting the roller sleeve in the horizontal direction, and are mainly used to support the weight of the roller body as a hanging groove. The internal and external fixing parts can be fixed with small-sized fixing bolts that are easy to disassemble and install;

3. When the roller sleeve is slidably installed into the hanging groove, the inner and outer fixing parts can also cooperate with the hanging groove to slide the roller sleeve;

4. An auxiliary fixing piece is also provided at one end of the roller sleeve relative to the inner and outer fixing pieces, so as to fix both ends of the roller sleeve at the same time after the inner and outer fixing pieces are locked, thereby ensuring the fixing strength;

5. The positions of the internal and external fixing parts are arranged relative to the power parts. When disassembling the roller body, multiple people can work together at the same time, and disassemble the internal and external fixing parts and power parts at both ends of the roller body at the same time, thereby improving the disassembly efficiency;

6. The positions of the inner and outer fixings also determine the installation position of the roller sleeve in the suspension component. That is, when the inner and outer fixings are pressed against each other, it indicates that the roller sleeve is installed in the correct position in the suspension component.

7. The fixing holes on the inner and outer fixing parts are arranged along the sliding direction of the roller sleeve. When the roller sleeve is installed in the correct position in the suspension component, the fixing holes on the inner and outer fixing parts are also aligned, and the fixing bolts can be directly installed.

DETAILED DESCRIPTION

The present invention is further described in detail below in conjunction with the accompanying drawings. It should be understood that the following embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

FIG1 illustrates the brush roller described herein, which comprises: a roller body 1, bristles arranged in an annular array on the surface of the roller body 1, a roller cover 3 detachably and rotatably connected to the roller body 1, and a suspension component 4 slidably engaged with the roller cover 3. It can be seen from the figure that the suspension component 4 is a groove body with an opening downward, and a plate extending inwards from the groove just receives the ears extending outwards of the roller cover 3. A rotatable mounting component coinciding with the axis of the roller body 1 is provided below the roller cover 3.

FIG. 2 shows the roller sleeve 3 after the suspension component 4 is removed from FIG. 1 , so as to more clearly show the structural scope of the roller sleeve 3 .

FIG3 illustrates the position of the power member 102 described herein, which is arranged at the other end of the rotatable mounting component on the roller sleeve 3 where the roller body 1 is mounted, and the diameter of the power member 102 in the figure is larger than the diameter of the cross section of the roller body 1, so that the roller body 1 is completely covered. The figure also shows the auxiliary fixing member 307 on the roller sleeve 3, which is arranged on the left and right sides of the roller sleeve body above one end of the power member 102.

FIG4 illustrates the specific structure of the suspension component 4 described herein. It can be seen that the main body of the suspension component 4 is composed of a plate body 403. The plate body 403 is divided into an upper plate 403a arranged at the top, side plates 403b on both sides of the upper plate 403a, and a lower plate 403c arranged below each side plate 403b. The upper plate 403a, the side plates 403b, and the lower plate 403c are generally formed in one piece to form the plate body 403 together, or they can be formed by welding or screwing. An internal fixing member 402 is provided on the top surface of the lower plate 403c, and the internal fixing member 402 is located on the left and right sides of the plate body 403. The dotted lines in the figure indicate the main space 401a and the side space 401b formed by the plate body 403.

In order to facilitate the observation of the circular arrangement of the bristles 2, only one layer of bristles 2 is shown in the figure, and the ratio of the diameter of the bristles 2 to the diameter of the roller body 1 is not standard, but the diameter of the bristles 2 is deliberately enlarged for the convenience of display.

<About the structure and function of bristles 2>

A brush 2 is arranged on a roller with a rotating shaft to be applied to the process of forming a texture on the surface of a plate, comprising:

Generally a root section 201 for mounting on a roller;

Generally, the head section 202 extends outwardly in a direction close to perpendicular to the rotation axis;

The spacing segment 203 is disposed between the general root segment and the general head segment and is used to isolate the distance between adjacent bristles.

Referring to FIG. 13 , a spacing structure of a spacing segment 203 produced by bending and deforming the bristle body is shown. The spacing structure is composed of a plurality of protrusions extending outward, and the protrusions can contact with the protrusions of adjacent bristles, so that the head segments 202 of the bristles are separated from each other, or stresses that separate from each other are generated. It can be seen that there is a certain randomness in the preparation process of the spacing structure (such as drawing or non-directional pressing), so that the spacing structures between each bristle are different, so that the spacing structures will not be exactly spliced together, causing the bristles to be densely contacted, resulting in the failure of the spacing structure.

Referring to Figure 15, another spacing structure is shown. In this structure, the spacing structure of each bristle is formed by drawing or pressing, and is a single arc-shaped structure protruding in the direction perpendicular to the extension direction of the bristles. Since the shapes of the production molds are the same or similar, the spacing structures have the same shape. However, the orientations of the various spacing structures can be different by different installation angles of the general root segment 201, which can also avoid the situation where multiple spacing structures are stacked together.

Referring to Figure 16, another spacing structure is also shown. In this structure, the spacing structure is formed by the cavity formed inside the body of the bristle 2, and then expanded. Due to the characteristics of the bristle material itself, the spacing structure has a certain degree of elasticity, and the spacing structure has a larger diameter than the general head segment and the general root segment. Because the spacing structure occupies a part of the space below the general head segment, the general head segments are separated from each other. Another advantage of this structure is that it eliminates the possibility of multiple spacing structures stacked together.

Referring to Figure 17, another spacing structure is also shown. In this structure, the bristles 2 include a bristle body and a sleeve 204, and the sleeve is sleeved on the outside of the bristle body to form the spacing structure. The material of the spacing structure can be the same as the material of the bristles (if the material constituting the bristles itself has good elasticity), or it can be made of a material different from the material of the bristles. It can be seen that in this embodiment, the general root segment and the general head segment are both partial structures of the bristle body that leak out of the spacing structure, that is, the bristle body has not been drawn or pressed. The advantage of this is that the general root segment and the general head segment are always on the same straight line in the extension direction of the bristles. When the specific position of the general root segment is determined, the specific position of the general head segment is also determined, which can improve the uniformity of the distribution of the bristles during use.

<Correlation between the external contour of the general head segment and the wire drawing ability>

The panels coated with the same amount of primer and inhibitor and cured for the same time were drawn with bristles of different diameters at the same distribution density, and then the residual degree of slow solid after drawing was evaluated to obtain the drawing ability α in %, and the formula is as follows:

α = (1- D1/D0) × 100%

Where:

α, wire drawing ability, %;

D1, the total mass of the slow solids remaining after the panel is drawn, g;

D0, total mass of initial slow solids of the panel, g;

It can be seen that the larger the α value is, the greater the wire drawing ability is, indicating that the slow solids can be removed more completely.

When the Z value increases, the α value increases first and then decreases with the increase of the Z value. The reason is that when the Z value is very low, the mechanical strength of the bristle head section 202 is not enough, and only part of the slow solidifying substances can be removed, and the slow solidifying substances with a higher degree of solidification cannot be removed; when the Z value is very high, the outer contour of the bristle head section 202 is too large, and it cannot reach the tiny gaps formed after some curable substances are completely solidified. The slow solidifying substances in these gaps cannot be removed by the bristles. Therefore, there is a specific value or a specific range of Z value to make the bristles have the maximum removal efficiency, that is, α is close to 100%.

It was found in the test that when Z = 0.5-1mm, α is approximately equal to 100%, that is, all slow solids are basically removed during the wire drawing process.

<Correlation of the external profile of the interval segment 203 with the C wire drawing capability>

Brushes with different diameters C were used with the same distribution density to draw the panels coated with the same amount of primer and inhibitor and cured for the same time, and their drawing ability α was evaluated. It was found that with the increase of C value, the drawing ability α first increased and then decreased. The reason is that when the C value is very small, the head sections 202 are generally not far apart and piled up together, resulting in the inability to remove the slow solids in some small gaps in time; when the C value is very large, the head sections 202 are generally too far apart, resulting in too sparse distribution, making it impossible to clean all the gaps, which will also cause slow solids to remain.

In addition, there is a critical value for the C value. When the critical value is exceeded, the bristles cannot be smoothly installed on the roller body because the overly thick interval segments make it impossible for the bristles to be installed together.

It was found in the test that when C = 2-3mm, α is approximately equal to 100%, that is, all slow solids are basically removed during the wire drawing process.

In addition, the test also found that when C>5mm, the bristles cannot be smoothly installed on the brush roller, and the wire drawing ability drops sharply.

<Correlation between the diameter C of the interval segment 203 and the adhesion ability of the slow solid to the general head segment of the bristle>

The panels coated with the same amount of primer and inhibitor and cured for the same time were passed through a brush roller at the same speed, and then the total mass of the slow solidifying substance adhering to the general head section was collected. The higher the mass, the higher the adhesion ability of the slow solidifying substance in the general head section, and the lower the corresponding cleaning ability β. β is an empirical value, which is negatively linearly correlated with the total mass of the slow solidifying substance adhering to the general head section.

The diameter C of the interval segment refers to the case where the vertical projection of the interval segment can be completely covered by the projection of the smallest circle, and the diameter of the circle is the diameter C of the interval segment. From the experimental results, it can be seen that within the allowable range of the C value, as the C value increases, the β value continues to decrease, indicating that the separated general head segment 202 has a lower tendency to adhere to slow solids.

It was found in the test that when C=3mm, the bristles can have the best drawing effect and relatively low adhesion to slow solids.

A brush roller comprises the above-mentioned bristles; the brush roller also comprises:

The roller body has a cylindrical structure and a rotating shaft arranged along the axis of the cylindrical body;

A guide groove is formed on the surface of the roller body and is open outwards and is used for installing the general root section of the bristle.

The guide groove bodies are groove bodies arranged in an annular direction on the surface of the roller body. FIG. 18 shows a setting state of the guide groove bodies, wherein each guide groove body is a closed-loop structure and is sleeved on the roller body.

In addition, the guide groove body can also be formed by hollowing out the surface of the roller body.

Referring to FIG. 18 again, it can be seen that the guide groove forms a bristle space, and the bristle space refers to the portion of the roller body where no bristles are provided. Due to the existence of the bristle space, the bristles are arranged on the roller body in an array along the traveling direction of the assembly line.

<Correlation between the width of the bristle space B and the adhesion of slow solids to the general head section of the bristles>

The panels coated with the same amount of primer and inhibitor and cured for the same time were passed through brush rollers with different bristle spaces B, and then the total mass of the slow solids adhered to the general head section was collected. The higher the mass, the higher the adhesion ability of the slow solids in the general head section, and the lower the corresponding cleaning ability β. The experimental results show that the β value decreases with the increase of the bristle space B. When B>1mm, the β value begins to decrease and eventually stabilizes at a specific value, basically around B=20mm, indicating that the bristle space B can reduce the tendency of the head section 202 to adhere to the slow solids to a certain extent. However, there is an upper limit to B improvement, especially when B>20mm, there are obvious gaps between the bristles, and the panel between the gaps cannot be subjected to the wire drawing process from the brush roller, resulting in partial loss of function of the brush roller.

<Specific structure and function of brush roller>

Referring to FIG1 , a brush roller comprises:

The roller body 1 has a cylindrical structure and has a rotating shaft 101 arranged along the center line of the cylinder;

Bristles are arranged on the surface of the roller body 1;

The roller sleeve 3 is used for rotatably mounting the rotating shaft 101 and is provided with an external fixing member 301;

The suspension component 4 is arranged above the conveyor belt in the assembly line. The suspension component 4 is provided with a suspension groove 401 for slidingly installing the roller sleeve 3 along the extension direction of the rotating shaft 101, and an internal fixing member 402 is arranged in the suspension groove 401 for fixing the external fixing member 301.

The bristles are arranged on the outer annular surface of the roller body 1 in a uniform arrangement, and the extension direction of each bristle is substantially aligned with the axis of the roller body, so that the bristles can vertically contact the panel to be drawn when moving to the lowest point.

The rotating shaft 101 is arranged along the axial direction of the roller body 1 , as shown in FIG. 5 .

The roller sleeve 3 is provided with a rotatable structure for mounting the rotating shaft 101, such as a bearing.

The various components of the roller sleeve 3 can be connected by welding, and some components can also be connected by bolts, so as to adjust the size to adapt to the suspension component 4.

Among them, the suspension component 4 is in the form of a groove body with the groove facing downward, the groove shrinks inward, and the upper end of the roller sleeve 3 expands outward, so as to have a sliding installation entering the inwardly contracted part of the groove of the roller sleeve 3, and the inwardly contracted part of the groove can accommodate the roller sleeve 3 and the roller body 1 installed thereon in the vertical direction.

Once the inner fixing member 402 is connected to the outer fixing member 301, it can prevent the roller sleeve 3 from sliding in the suspension component 4, and can limit the movement of the roller sleeve 3 and the roller body 1 installed thereon in the horizontal direction, thereby limiting the movement tendency of the roller body 1 except for axial rotation, thereby achieving the fixation of the roller body 1.

Referring to FIG2 , the effect after the roller sleeve 3 is removed from the hanging component 4 is shown, so as to more clearly show the connection mode between the roller sleeve 3 and the roller body 1. In this example, the lateral distance of the upper end of the roller sleeve 3 is longer than the diameter of the brush roller formed by the roller body 1 and the bristles, that is, after the roller sleeve 3 is removed from the hanging component 4, other devices with two-end fixings can also be used to immediately fix the part extending to both sides of the upper end of the roller sleeve 3, so as to realize the functions of rapid fixing, transportation, storage, etc. of the roller body 1.

4 , the hanging groove 401 includes a main space 401 a and side spaces 401 b extending toward both sides of the main space 401 a ; the inner fixing member 402 is disposed inside the hanging member 4 and arranged in the side space 401 b .

The suspension component 4 includes a plate body 403 for forming the suspension groove 401, and the plate body 403 includes an upper plate 403a, side plates 403b arranged at both side ends of the upper plate 403a, and a lower plate 403c arranged at the lower end of the side plate 403b; the upper plate 403a includes an upper plate side area vertically opposite to the lower plate 403c, and an upper plate middle area located between the two upper plate side areas; the upper plate side area, the side plate 403b and the lower plate 403c define the side space 401b, and the upper plate middle area defines the main space 401a.

Among them, the upper plate 403a, the side plate 403b and the lower plate 403c can be in an assembled relationship, or can be formed by the plate body 403 itself being integrally formed. When the plate body 403 itself is integrally formed, the upper plate 403a, the side plate 403b and the lower plate 403c are only used to represent different parts of the plate body 403 itself.

The inner fixing member 402 is disposed on the upper end surface of the lower plate 403c.

6 , the roller sleeve 3 includes a roller mounting member 302 for rotatably mounting the rotating shaft 101 , a suspension plate 303 for mounting the roller mounting member 302 , and hanging ears 304 arranged on both sides of the hanging plate 303 ; the external fixing member 301 is arranged on the lower end surface of the hanging ear 304 .

In the process of the roller sleeve 3 slidingly installed into the suspension component 4, the following events occur in sequence:

T11. The suspension plate 303 is always located in the main space 401a, and the ears 304 on both sides of the suspension plate 303 are always located in the side space 401b;

T12. Continue to slide the roller sleeve 3 inward, the ears 304 on both sides of the suspension plate 303 simultaneously contact the upper edge of the inner fixing member 402, and the suspension member 4 realizes the support function of the roller sleeve 3 in the vertical direction;

T13. The roller sleeve 3 is continued to slide inward. Since the outer fixing member 301 and the inner fixing member 402 have substantially the same height, the outer fixing member 301 also contacts the upper edge of the lower plate 403c. At this time, the inner fixing member 402 and the upper edge of the lower plate 403c simultaneously support the roller sleeve 3. The positional relationship between the outer fixing member 301 and the inner fixing member 402 is shown in FIG8 .

T14. Continue to slide the roller sleeve 3 inward, the outer fixing member 301 and the inner fixing member 402 are pressed together, and the roller sleeve 3 cannot be slid inward any further, which means that the installation process of the roller sleeve 3 in the suspension component 4 is completed, that is, the outer fixing member 301 and the hanging ear 304 form an installation profile configured in the shape of the inner fixing member 402. The positional relationship between the outer fixing member 301 and the inner fixing member 402 is shown in FIG9 .

8-9 , the outer fixing member 301 and the inner fixing member 402 are respectively configured with fixing holes of the same specification, and are simultaneously inserted and fixed by the fixing bolts 5 .

The fixing hole has a central axis parallel to the axial direction of the roller body 1 , that is, when the outer fixing member 301 and the inner fixing member 402 are pressed together, the two fixing holes simultaneously form a whole fixing hole, which is convenient for directly installing the fixing bolt 5 , as shown in FIG. 10 .

The fixing hole on the inner fixing member 402 does not have to pass through the entire inner fixing member 402, but only needs to be designed according to the actual length of the fixing bolt 5. The fixing hole in the outer fixing member 301 needs to pass through the entire outer fixing member 301 to facilitate the installation of the fixing bolt 5 at its outer end and the connection of the inner end with the fixing hole on the inner fixing member 402.

The inner fixing member 402 should continue to extend to the far end of the lower plate 403c, so as to provide sufficient support to the hanging ear 304 during the entire sliding installation process of the roller sleeve 3. The inner fixing member 402 can be multiple and intermittently arranged along the lower plate 403c, and the fixing hole is only arranged in the inner fixing member 402 at the nearest end.

The fixing bolt 5 can fix the external fixing member 301 and the internal fixing member 402 by screwing, that is, a fixing internal thread is provided in the fixing hole, and the fixing bolt 5 is provided with a fixing external thread arranged on the fixing internal thread.

Referring to Fig. 6 again, the roller sleeve 3 further comprises an end handrail 305 disposed at the proximal end of the suspension plate 303. The end handrail 305 is used to pull the roller body 1 outward when the roller body 1 is removed from the suspension component 4, and is used to cooperate with the upper end surface of the internal fixing member 402 to support the two ends of the roller sleeve 3 when the roller sleeve 3 is removed outward.

Referring again to Fig. 8-9, the roller sleeve 3 further includes a side handrail 306 disposed on the outer side of the hanging ear 304. When the transfer device is used to load the part of the roller sleeve 3 that has been disassembled outward, it is necessary to release the support of the end handrail 305, and this process easily causes the roller sleeve 3 to slide outward unstoppably, causing safety risks. The side handrail 306 can assist in supporting the side of the roller sleeve 3 during the disassembly process, so as to allow the support of the end handrail 305 to be temporarily cancelled and the proximal end of the roller sleeve 3 to be smoothly loaded into the transfer device.

In addition, when the roller sleeve 3 is disassembled outward, when nearly half of the volume of the roller sleeve 3 is removed from the suspension component 4, the center of gravity of the roller sleeve 3 is about to leave the support area of the suspension component 4. Specifically, the center of gravity of the roller sleeve 3 leaves the area that can be supported by the upper end surface of the inner fixing member 402, and there is a risk of tilting outward. Only one person holding the end handrail 305 is not enough to resist this overturning force. The side handrail 306 on the side of the roller sleeve 3 can also allow the staff to assist and support from the side, further stabilizing the process of sliding the roller sleeve 3 outward.

The side handrail 306 is a groove handrail formed by the outer side of the hanging ear 304 being recessed inward. The advantage of the groove handrail is that when the roller sleeve 3 is slidably installed into the hanging component 4, the side handrail 306 is located on the inner side of the hanging ear 304 as a whole, so that when the hanging ear 304 slides on the upper end surface of the inner fixing member 402, the fitting state between the side and the side plate 403b is not affected, or the side plate 403b can cooperate with the upper end surface of the inner fixing member 402 to limit the sliding process of the hanging ear 304.

Referring to Figures 11-12, the roller sleeve 3 also includes an auxiliary fixing member 307 disposed at the far end of the suspension plate 303; the suspension component 4 also includes an auxiliary receiving member 404 disposed on the plate body 403 and used to install the auxiliary fixing member 307. The auxiliary fixing member 307 and the auxiliary receiving member 404 are fixed by plugging and fixing, so as to limit the horizontal and vertical positions of the far end of the roller sleeve 3. This displacement does not limit the sliding behavior of the roller sleeve 3 toward the proximal end, because this behavior has been well limited in the fixing process of the outer fixing member 301 and the inner fixing member 402 through the fixing bolt 5, and the installation process of the auxiliary fixing member 307 and the auxiliary receiving member 404 is also completed in one step through the behavior of the roller sleeve 3 sliding toward the far end in the suspension component 4.

Referring to Figure 3, the roller body 1 is further provided with a power member 102 at the far end thereof; the power member 102 provides rotational power to the roller body through a transmission member connected to a power device. The power member 102 is a turntable coaxially arranged with the roller body 1, and the purpose of driving the roller body 1 to rotate can be achieved by driving the turntable to rotate through the transmission member.

The transmission member is a transmission belt. Compared with transmission methods such as gears, the transmission belt itself is flexible. When disassembling the roller body 1, as long as the transmission belt is loosened, the roller body 1 can be disassembled from the power member 102.

In summary, a method for disassembling a brush roller comprises the following steps:

S01. Remove the locking device between the inner fixing member 402 and the outer fixing member 301;

S02. Pull the roller sleeve out of the hanging groove.

In S01, the following steps are also included:

S01-1. Remove the drive belt from the power member 102;

S01-2. Remove the fixing bolt 5 on the inner fixing member 402 and the outer fixing member 301;

S01-3. Pull the roller sleeve outward from the suspension groove so that the auxiliary fixing member 307 is removed from the auxiliary receiving member 404.

In S02, the following steps are also included:

S02-1. Pull the roller sleeve partially out of the hanging groove, and use a transfer device to support the protruding portion of the roller sleeve from the hanging groove;

S02-2. Continue to pull the roller sleeves until all roller sleeves are disengaged from the hanging grooves and completely enter the transfer device.

In addition, in another solution of step S02, the following steps are also included:

S02-1. Support the end handrail 305, pull the roller sleeve partially out of the hanging groove, so that the side handrail 306 is moved out of the hanging groove 401;

S02-2. Support side handrails 306 to assist end handrails 305;

S02-3. Move the transfer device to the proximal end of the roller sleeve 3 and adjust the height of the support device on the transfer device to be flush with the roller sleeve 3;

S02-4. Loosen the end handrail 305 and move the proximal end of the roller sleeve 3 into the transfer device through the side handrail 306.
