The composite board is formed by clamping core materials in the middle of metal plates at two sides, is widely used, and is represented by a clean plate, and is widely applied to the fields of clean engineering with severe requirements on indoor environments, such as electronics, pharmacy, food, biology, aerospace, precision instrument manufacturing, scientific research and the like.
The production of the clean plate is in a semi-manual state all the time, especially the assembly work of the metal plate, the frame and the core material of the clean plate. Specifically, the cleaning plate is manufactured by processing a metal plate into a box shape (hereinafter referred to as an upper box body and a lower box body) by using equipment, processing a frame to meet the size requirement of the box in which the metal plate is placed, and then manually assembling.
The manual assembly work comprises the steps of firstly lifting a lower box body on a designated station by workers, then placing a frame into the lower box body, then taking core material blocks or plates (such as rock wool blocks, glass magnesium plates, aluminum honeycomb plates, magnesium oxysulfide plates, silicon rock plates, gypsum plates and the like), cutting embedded grooves on the core material blocks, then placing the core material into the frame of the lower box body in an assembled mode to form a layer (the core material is filled for a single-layer core material), then placing a threading pipe into the embedded grooves, correspondingly paving the multi-layer core material if the core material is a composite plate of the multi-layer core material, continuously assembling other core material layers after the core material layers of the embedded grooves are paved, finally forming multi-layer composite core materials, cutting the core material blocks or plates to fill the space in the frame until the core material blocks or plates are filled with the frame, finally taking the upper box body and fastening the core material blocks to cover the lower box body, completely wrapping the core material and the frame, and extruding the core material into a machine to firmly wrap the core material and the core material in the middle of the lower box body.
As can be seen from the above, in manual production, the worker not only needs to assemble the core material and cut the core material into the frame, but also needs to process the embedded groove and place the threading pipe on the corresponding core material, and the worker must operate sequentially corresponding to the single composite board, which is not only time-consuming and labor-consuming, but also has low efficiency, and cannot achieve continuous production.
In order to solve the above problems, the inventor found that it is necessary to perform automatic production of composite boards, including automatic transfer of metal plates into upper and lower cases along a production line, automatic molding of core materials (composite core materials of at least two layers) having a size and number of layers conforming to the inside of a frame, automatic transfer of the frame into the production line, and automatic assembly of the upper and lower cases, core materials, and frame on the production line. The application relates to an automatic forming method of a core material for automatic production of a composite material, specifically:
As shown in fig. 1, an embodiment of the present application provides a method for producing a core material of a composite board, for automatic production of a composite board, including:
101. and continuously transmitting the first core material in a first direction in a contact mode from beginning to end to form a continuously extending first core material layer.
Specifically, the first core material may be one of rock wool, glass magnesium board, silica rock board, glass silk floss, gypsum, etc., and may be specifically selected according to the production requirement.
Wherein the first direction is the transmission direction of the production transmission line. In the automatic production of composite board, can set up suitable snatch or suction means according to the characteristics of first core raw materials to put into production transmission line with first core raw materials, for example first core raw materials is massive (like rock wool), then can take first core raw materials from the windrow or feedway and put into production transmission line, if first core raw materials is platy, then also can adopt the mode of snatching to go up the line, perhaps also can adopt the mode of sucking or other movable first core raw materials to put into production transmission line on, as long as can be with first core raw materials stable and accurate put into production transmission line promptly. In order to enable the first core material to form a continuously extending first core material layer without gaps, so as to ensure the subsequent processing of the continuous embedded groove, the first core material needs to be sequentially and continuously transmitted in a contact mode, for example, the first core material is sequentially and continuously arranged on a production transmission line along the transmission direction, whether a block body or a plate body is in contact with the first core material in the contact mode, and then a continuously extending transmission state, namely, the continuously extending first core material layer is formed.
Furthermore, when the first core material layer is formed, the first core material can be in no connection relation, as long as continuous end-to-end contact is maintained, when the composite board is used as a core material of a single-layer core material, the first core material layer can be adhered between the upper box body and the lower box body through glue sprayed on the upper box body and the lower box body to form a stable core material;
Or at least one of the head end and the tail end of the first core material can be glued (glue spraying, glue spraying or glue rolling can be performed), the subsequent glue spraying can be adaptively selected according to specific conditions, for example, the head end glue spraying, the tail end glue spraying or the head end and the tail end of the first core material can be glued, namely, only the two adjacent first core materials are ensured to be used for being glued, at least one of the two ends of the first core material is provided with glue, the head end and the tail end are the head end and the tail end of the first core material along the transmission direction, then the glued first core material is sequentially put into a production transmission line, the first core material sequentially put into the production transmission line is sequentially glued and transmitted in a head-tail mode, and then a first core material layer connected with the head end and the tail end of the adjacent first core material is formed.
When the end part of the first core material is glued in a glue spraying mode, a glue spraying opening of the glue spraying device can be arranged above the first core material and is provided with a certain angle with the end part of the first core material to spray glue at a depression angle, or the glue spraying opening of the glue spraying device can be arranged below the first core material and is provided with a certain angle with the end part of the first core material to spray glue at an elevation angle. The two glue spraying modes can spray along with the movement of the first core material relative to the glue spraying opening (the movement of the first core material or the movement of the glue spraying opening) when the glue is required to be sprayed on the upper surface or the lower surface of the first core material.
Still further, when gluing the end portion of the first core material, the first core material may be in a static state, for example, may be in a suspended static state after being picked up, and the gluing is performed in such a state, and the setting position of the gluing device is relatively convenient. Or when the end part of the first core material is glued, the first core material can be in a motion state along the transmission direction, for example, the grabbing equipment can grab the first core material and then move along the transmission direction with the first core material, and the end part gluing is performed in the moving process, so that the first core material can quickly catch up with the transmission speed of the production line after gluing or quickly move to the upper part of the production line, and the production rhythm is accelerated.
In order to make the adjacent two first core materials well adhere, the first core materials put into the production transmission line can be transmitted along with the production transmission line according to the sequence of putting the first core materials into the production transmission line, namely, the first core materials to be put into the production transmission line have the same speed as the production transmission line, the first core materials to be put into the production transmission line are endowed with the speed which is faster than that of the first core materials on the production transmission line, the speed difference can be set to 15% -25%, for example, 20%, then the first core materials to be put into the production transmission line later collide with the tail ends of the first core materials positioned on the production transmission line, and extrusion force is given to the two first core materials, so that the two first core materials can well adhere. And finally, connecting the first core material positioned on the production transmission line into a first core material layer, and transmitting according to the transmission speed of the production transmission line. In addition, the first core material to be put into the production transmission line can be endowed with the transmission speed equal to that of the production transmission line, after the production transmission line is tracked to transmit the first core material for a period of time, the first core material to be put into the production transmission line is accelerated to have the speed greater than that of the first core material on the line, and finally, after the first core material with the higher speed is put into the production transmission line, the adjacent two first core materials are collided, so that the end parts are tightly bonded. The bonding mode is performed after the speed tracking, so that the bonding efficiency of the two end parts can be ensured, and the front and rear first core material raw materials can move relatively stably.
102. Along with the extension and transmission of the first core material layer, continuous embedded grooves are processed on the upper surface of the continuously extended first core material layer.
Specifically, the first core material layer is continuously formed, that is, the first core material is continuously placed on a production transmission line in a contact mode from beginning to end, and is continuously transmitted, or at least one of the end to end of the first core material is glued, and then the first core material is placed on the production transmission line in a contact mode from beginning to end. And meanwhile, dust collection equipment arranged above the production transmission line, namely above the first core material is utilized to suck away flying scraps generated by milling, so that the production environment is prevented from being polluted by dust and flying scraps, wherein the embedded groove processed in a milling mode is a continuous groove with a rectangular section. Thus, the first core material layer with the embedded groove can be continuously and automatically produced.
The number of the embedded grooves is not limited to one, and when two or more embedded grooves are needed, the embedded grooves are needed to be milled side by side and at intervals. The milling device may be arranged fixedly above the production line or in a state in which it is movable relative to the production line, for example the milling cutter of the milling device may be moved in a direction opposite to the first direction.
It should be noted that in order to allow stable and less play of the threading tube in the pre-buried groove, the width and depth of the pre-buried groove are preferably sized to be greater than 1-2mm of the diameter of the threading tube.
103. And continuously placing the threading pipe in the continuous embedded groove to form a first core material layer which extends continuously and is embedded with the continuous threading pipe.
Specifically, steps 101 to 103 are continuous, i.e. may be performed on a continuously transported production line, and after the continuous pre-buried groove is milled in the continuously extending first core layer, the threading pipe may be continuously placed in the pre-buried groove along with the transportation of the first core layer.
The threading pipes can be placed into the embedded groove section by section or one by one, but the head and the tail of two adjacent threading pipes are ensured to be in contact or infinitely close. In a specific embodiment, the threading pipe can be placed into the pre-buried groove by the following method:
along with the continuous transmission of the first core material layer, the threading pipes are rolled into the embedded groove in a rolling pipe falling mode, wherein the ends of the threading pipes are close to each other in sequence;
That is, a device for rolling down the threading pipe is arranged at the rear of the milling station of the embedded groove, and when the distance of the transmission extension of the first core material layer is equal to the length of the threading pipe, one threading pipe rolls down into the embedded groove, so that the threading pipe falls into the embedded groove, and meanwhile, the adjacent two threading pipes are connected end to end.
Or, along with the continuous transmission of the first core material layer, pushing the threading pipe to fall into the embedded groove above the embedded groove along the first direction by adopting a pushing groove-entering mode, and enabling the head end of the threading pipe which is inserted into the embedded groove to prop against the tail end of the threading pipe which is inserted into the embedded groove;
The threading pipe is continuously pushed until the distance of the transmission extension of the first core material layer is equal to the length of the threading pipe, the first end of the threading pipe can firstly fall into the embedded groove when the threading pipe does not completely fall into the embedded groove, then the threading pipe completely falls into the embedded groove when the distance of the transmission extension of the first core material layer is equal to the length of the threading pipe, and attention needs to be paid to ensure that the head end and the tail end of the threading pipe which falls into the embedded groove after the adjacent two threading pipes are pushed are connected, and the threading pipe which falls into the embedded groove after the threading pipe is pushed to top of the tail end of the threading pipe which falls into the embedded groove.
Compared with the prior art, the method for producing the core material of the composite board provided by the application has the advantages that the first core material is continuously transmitted in a contact mode from beginning to end to form the continuously extending first core material layer, when the first core material layer is continuously extended and transmitted, the upper surface of the first core material layer is processed with the continuous embedded groove, then the embedded groove is continuously placed into the threading pipe, and finally the continuously extending core material with the continuous threading pipe is formed. Therefore, after the first core material layer which extends continuously and is embedded with the threading pipe is produced, a user can automatically cut the first core material layer which extends continuously to a certain size by using cutting equipment according to the requirement of the produced composite board on the size of the first core material layer, so that the first core material layer with the integral size meeting the requirement can be automatically obtained, and the first core material layer can be automatically cut into different sizes according to the requirement of the composite board with different sizes on the core material, so that the same production line can automatically produce the composite boards with different types.
In a specific embodiment, in order to enable the connecting force between the threading pipe and the embedded groove, the threading pipe can be continuously placed in the embedded groove after being glued in the continuous embedded groove, or the whole upper surface of the continuously extending first core material layer after the continuous embedded groove is processed is glued, and then the threading pipe is continuously placed in the embedded groove.
Specifically, the glue can be sprayed, sprayed or brushed in the pre-buried groove, or sprayed, sprayed or brushed on the whole upper surface of the first core material layer, or continuously sprayed, sprayed or brushed, or intermittently sprayed, sprayed or brushed, and the sizing device can move relative to the first core material layer during sizing.
The threading pipe is placed in the embedded groove, and then glue is sprayed, glue is sprayed or glue is brushed by rolling, however, whether glue is applied in the embedded groove in advance or not, or glue is applied after the threading pipe is placed in the embedded groove, the upper surface of the first core material layer can be rolled in a rolling mode after the threading pipe is placed in the embedded groove, so that the threading pipe can be guaranteed to fall into the embedded groove completely.
As shown in fig. 2, an embodiment of the present application provides another method for producing a core material of a composite board, for use in the automated production of a composite board, including:
201. And continuously transmitting the first core material in a first direction in a contact mode from beginning to end to form a continuously extending first core material layer.
202. Along with the extension and transmission of the first core material layer, continuous embedded grooves are processed on the upper surface of the continuously extended first core material layer.
203. And continuously placing the threading pipe in the continuous embedded groove to form a first core material layer which extends continuously and is embedded with the continuous threading pipe.
Specifically, the steps 201 to 203 may refer to the specific implementation manners of the steps 101 to 103 in the above embodiments, which are not described herein again.
204. And adhering second core material to the upper surface and/or the lower surface of the continuously extending first core material layer in sequence in a head-to-tail contact manner to form a second core material layer, and laminating at least one layer of the second core material layer to form a continuously extending composite core material, wherein the materials of the second core material layers are the same or different.
Specifically, when the continuous pre-buried groove is formed by milling the continuous first core material layer, and the continuous threading pipe is placed in the pre-buried groove, the second core material layer can be further arranged on one side or two sides of the first core material layer in a laminated manner according to the requirement of the composite board on the number of core material layers.
The composite core material formed based on the continuously extending first core material layer may be a two-layer core material or a multi-layer core material. When the two layers of core materials are adopted, the second core materials can be adhered on the upper surface or the lower surface of the first core material layer in an end-to-end contact mode, when the two layers of core materials are adopted, the second core materials can be sequentially laminated on the upper surface or the lower surface of the first core material layer, or the second core materials can be symmetrically adhered on two sides of the first core material layer, and the total number of layers is an odd number, such as 3 layers, 5 layers, 7 layers or more. It should be noted that the second core material of each layer needs to be adhered to the first core layer or the adjacent second core layer in a contact manner from end to end, for example, the second core layer may be formed by adhering the first core material to the first core layer while the first core layer is continuously extended and transported along the reverse direction of the transport direction of the first core layer.
The second core material can be one of a plurality of materials such as rock wool, paper honeycomb, glass magnesium board, aluminum honeycomb, magnesium oxysulfate, silicalite, gypsum and the like, and can be specifically selected according to the production requirement. The materials of the two adjacent second core material layers can be the same or different, or the materials of the second core material layers symmetrically arranged at the two sides of the first core material layer can be the same or different, and the two adjacent second core material layers can be specifically arranged according to the requirements of the composite board.
Further, the method of laminating the second core material on the first core material layer may be:
and/or gluing the lower surface of the second core material, and bonding the second core material on the upper surface of the first core material layer by layer.
Specifically, when the second core material is adhered to the lower surface of the first core material layer, the upper surface of each second core material can be coated with glue, then the coated second core material is adhered to the lower surface of the first core material layer in a contact mode along the reverse direction of the conveying direction of the first core material layer (the first core material layer is continuously extended and continuously conveyed), when the second core material is adhered to the upper surface of the first core material layer, the lower surface of each second core material can be glued, then the glued second core material is adhered to the upper surface of the first core material layer in a contact mode (the first core material layer is continuously extended and continuously conveyed), when the second core material is required to be adhered to the upper surface and the lower surface of the first core material layer respectively, the second core material is respectively positioned on the upper side and the lower side of the first core material layer, the lower surface of the second core material positioned below the first core material layer is glued, then the second core material with the second core material is sequentially extended and simultaneously adhered to the upper surface of the first core material layer and the lower core material layer.
205. And pressing the composite core material along the thickness direction perpendicular to the composite core material, and performing thickness trimming.
Specifically, in the case of a continuous and laminated composite core material, the thickness of the entire composite core material does not meet the practical application requirements during lamination and adhesion, and therefore, it is necessary to trim the composite core material in the thickness direction.
In consideration of the fact that the composite core material is continuously extended in the transfer motion, the following method may be adopted when the thickness trimming is performed by pressing the composite core material in the thickness direction:
And rolling and pressing the composite core material in the process of conveying the continuously extending composite core material. For example, a rolling device can be arranged on a production transmission line, a row of multiple rollers or rollers can be arranged above the production transmission line, the thickness direction size is limited by fixing the rollers or rollers, when the composite core continuously extends to pass through a thickness space defined between the rollers or rollers and the production transmission line, the rollers or rollers are driven by the composite core to rotate, the thickness is trimmed by rolling in the thickness direction, or the composite core is subjected to rolling pressure from top to bottom, namely, the rollers or rollers arranged above the production transmission line can be arranged to move relative to the production transmission line, and then the pressure can be applied to the composite core from top to bottom, so that rolling pressure is applied while the composite core passes through, and the thickness of the composite core is trimmed. And when the thickness of the composite core material is trimmed in a rolling mode, the threading pipe is further pressed into the embedded groove and is well combined with the embedded groove.
Further, in the method for performing the thickness trimming of the composite core material, the composite core material may be heated by hot air while rolling and pressing the composite core material, for example, by using hot air at 60-70 ℃ to promote the thickness trimming effect.

The method of trimming the two sides of the continuous composite core material in the width direction can be to trim by using a cutter to move up and down, or saw cutting by using a saw blade, or milling of the side end faces by using a reamer, namely, only the two sides of the continuous composite core material in the width direction can be trimmed to be straight.
In addition, the present application mainly provides continuous molding of the composite core material in the composite board, but for the production method of the composite board, in order to realize automatic production, the method may further include:
Along with the continuous forming of the core material, the upper box body and the lower box body are formed and enter the production transmission line, the inner parts of the upper box body and the lower box body can be glued after entering the production transmission line, and then the upper box body and the lower box body are parallel to the composite core material on the production transmission line, namely, the forming equipment of the upper box body and the lower box body is connected with the production transmission line;
After the frame is also preformed, the frame is conveyed to an upper frame station of the production transmission line (the station is positioned before a station where the composite core material is cut into a core material with a proper size for framing), and the frame is automatically conveyed to the production transmission line through a conveying device and is conveyed on the production line;
after cutting the prepared single-layer core material with the embedded threading pipe or the composite core material with the embedded threading pipe into the core material with the proper size for framing, simultaneously conveying the frame and the cut core material to the next station, framing the cut core material for framing at the station (the core material can be slid into the frame from top to bottom or covered into the frame from top to bottom through the frame), and then conveying the frame, the inner core material and the upper box body on the production line synchronously;
Then, when the frame and the lower box body filled with the core material move to the next station (a box-in station), the frame and the core material simultaneously enter the lower box body (the frame and the core material can slide into the lower box body from top to bottom), and the lower box body carries the frame and the core material together with the upper box body to continue to be transmitted on a production transmission line;
Finally, when the lower box body moves to the next station (buckling station) together with the upper box body and the frame and the core material, the equipment for overturning and buckling can overturn and buckle the upper box body on the lower box body, so that the assembly work of the composite board is completed.
Then, the product can be automatically transmitted to a profiling device for profiling, and the product can be taken off line after profiling. The above-mentioned every action can be arranged on the same transmission production line, and can be synchronously transferred along the same direction, and according to the time consumed by every working step and transfer speed the distance between every working steps, i.e. adaptive regulation time interval can be set so as to make two components to be combined meet in the combining working position, and can implement combination in the combining working position; in addition, the production methods can be set in a program mode, the control program is written into a controller or a host computer, and then an automatic production line is formed by combining equipment capable of automatically transmitting and realizing the actions of the steps, so that automatic production of the composite board is realized.
