Description

A spherical material storage and output device with a detachable chassis

Technical Field

The present invention relates to the field of material ejection devices, and more particularly to a spherical material storage and output device with a detachable chassis.

Background Art

The existing bullet wheel structure in the market is widely used. There are applications such as ball storage and controllable serving in ball sports serving machines in sports, such as table tennis serving machines, tennis serving machines, etc. Now with the continuous improvement of people's living standards, people pay more and more attention to the quality of life, and interesting leisure sports are becoming more and more popular among people.

Most of the existing spherical material storage and output devices have complex structures, and the magazine and chassis are completely fixed, which makes it inconvenient to disassemble and maintain, and the discharge is stuck. The reason for the inconvenience of cleaning and maintenance is that the ejection chassis is fixed with screws and cannot be quickly disassembled when necessary. The reason for the unsmooth discharge is that the motor shaft is limited by the "cantilever beam type". The ejection wheel is fixed on the motor shaft in a cantilever beam type with only one shaft, which causes the ejection wheel to shake too much, and the material is easily stuck due to the extrusion caused by the shaking of the ejection wheel; the flat-bottomed ejection chassis, the ejection wheel ejects the bullet in the cylindrical bullet cavity, and the material such as rubber bullet can only move in a horizontal plane. Once the bullet is stuck, it is difficult to solve the problem by simpler methods such as reversal, and the system reliability is not high; when the material is output, a square entry pipe is directly used, and then it is transitioned to a circular pipe output, which causes the material to lose some kinetic energy when it is output, and the transition is not smooth enough due to the limitation of the transition distance, which is easy to cause output blockage.

Summary of the invention

In order to overcome the problems in the prior art that the spherical material storage and output device is inconvenient to disassemble and the material output is not smooth, the present invention provides a spherical material storage and output device with a detachable chassis, which can quickly disassemble the chassis and make the material output smoother.

In order to solve the above technical problems, the technical solution adopted by the present invention is: a spherical material storage and output device with a detachable chassis, including a magazine for placing materials, a chassis provided with an ejection outlet, a motor and a ejection wheel connected to the motor and extending into the chassis, the chassis is provided with a positioning groove, the magazine is provided with two opposite openings, and one of the openings faces the chassis and cooperates with the positioning groove; the magazine is detachably connected to the chassis; the motor is installed in the magazine.

The magazine is a cavity with only four side panels, which can be connected by four side panels through angle brackets. Positioning slots are set around the chassis, and the side panels are installed in the positioning slots to limit the horizontal freedom of the magazine. The chassis and magazine are detachably connected by snap connections and lock connections to ensure vertical constraints. When it is necessary to clean materials or replace accessories, the chassis and magazine can be directly disassembled and the materials in the magazine can be directly dumped out. Under normal use, spherical materials are placed in the magazine, and the materials fall into the chassis due to gravity. The spherical materials are pushed out of the chassis from the ejection outlet while the ejection wheel driven by the motor rotates.

Preferably, the magazine is detachably connected to the chassis via a lock buckle, which enables quick installation and removal of the chassis and magazine, and the connection of the lock buckle is more durable.

Preferably, a cantilever beam for mounting a motor is installed in the magazine, and a motor housing for wrapping the motor is arranged on the cantilever beam. The motor can be completely placed in the motor housing, so that the motor is not exposed inside the device, and the geometric shape of the device is more regular.

Preferably, the motor is connected to the ejection wheel via a ejection shaft; the ejection wheel is provided with a through hole, the ejection shaft passes through the through hole and is detachably connected to the ejection wheel; one end of the ejection shaft is connected to the motor, and the other end is rotatably connected to the chassis. The ejection wheel is connected to the ejection shaft so that the ejection wheel is no longer suspended, and is more stable when working, reducing the radial vibration of the ejection shaft and the periodic shear stress fluctuation of the ejection wheel caused by it, and significantly improving the output stability and service life of the output device.

Preferably, the ejector wheel is provided with at least one mounting hole, and the ejector shaft is provided with a fixing hole matched with the mounting hole; one end of the ejector shaft is connected to the output shaft of the motor through a shaft tube, and the other end is rotatably connected to the chassis through a bearing. The mounting hole of the ejector wheel and the fixing hole of the ejector shaft are connected by inserting a fixing member, wherein there are preferably two mounting holes, which are perpendicular to each other, so as to ensure the transmission of the ejector shaft and the ejector wheel and avoid radial deviation of the ejector wheel.

Preferably, the pushing teeth of the ejector wheel are gear-type. The ejector wheel adopts gear-type pushing teeth and has a gear involute, so that the spherical material can continue to be subjected to the main force in the same direction. Regardless of whether the spherical material is in the process of moving on a circular trajectory or leaving the circular trajectory to enter the ejection outlet, the gear involute can ensure that the main force of the ejector wheel on the spherical material is in the same direction, which effectively reduces the extrusion between the spherical material and the side wall, and minimizes the possible sliding friction of the spherical material.

Preferably, a conical frustum is provided on one side of the ejector wheel close to the motor. The conical frustum is used to guide the trajectory of the spherical material in the ejector chassis so that it flows into the tooth groove of the ejector wheel, thereby preventing the spherical material from piling up or pausing without entering the chassis.

Preferably, the chassis is provided with a trajectory for placing spherical materials, the trajectory is connected to the ejection outlet, and the trajectory is provided with a spiral slope. The spiral slope chassis can make better use of the mass properties of the material itself, and a spiral ramp is added to the bottom of the ejection plate. Relying on a certain slope, the material can slide down the spiral slope with the help of its own gravitational potential energy, reducing the pressure requirement for the power output of the ejection wheel. Once a jam occurs, the ejection wheel can be reversed to achieve ejection, and the material can climb with the help of the spiral slope, which can solve the ejection and jam problems as much as possible.

Preferably, the side wall of the trajectory is arc-shaped, and the radius of the arc is the radius of the ejected material. If there are too many spherical materials (output objects) piled up above the chassis, the spherical materials leaning against the side wall can be squeezed upward along the spherical side wall by the ejection wheel, which is equivalent to flipping the materials in the chassis. Moreover, since there is a larger movement space when pushing upward on the arc surface than on the cylindrical side wall, the risk of the material being stuck between the side wall and the ejection wheel is effectively reduced. At the same time, due to the effect of the arc surface, the gravity of the upper material is no longer directly superimposed on the lower material, but is subject to the effect of a gravity component parallel to the arc surface, and the component is smaller as the distance to the bottom is closer. When the ejection wheel ejects the material, it can effectively reduce the influence of other materials accumulated in the ejection chassis on the material trajectory and force in the track. In terms of the track of the rotational movement of the spherical material, the chassis uses the spiral gradually deepening depression on the arc surface that passes through the material output port as the spherical material track of the ejection chassis. The inclination tangent value of the spiral track is less than the friction coefficient between the material and the ejection chassis, and friction loss is avoided as much as possible. Finally, the spiral track is smoothly connected to the material input port to ensure the continuity and stability of the entire bullet removal process, effectively increasing the guiding efficiency of spherical materials.

Preferably, the connection between the trajectory and the ejection outlet is rounded, and the protruding edges are removed, eliminating the risk that the original side wall angle is low, there will be a jam between the top of the output interface and the ejection wheel, and when the ejection wheel rotates at a high speed, there may be a risk that the spherical material is not pushed into the ejection outlet and is stuck between the ejection wheel and the straight wall. The ejection outlet is provided with a preset device, so that in actual use, the flow rate of the ejection through the ejection outlet or the pipeline port and whether the ejection is continuous can be timely obtained, which ensures that the relevant parameters can be fed back in time.

Compared with the prior art, the beneficial effects of the present invention are: the chassis and magazine of the device can be quickly disassembled, and the chassis can be quickly and conveniently replaced or cleaned. When cleaning and maintenance are required, the chassis can be easily removed by simply opening the buckle, and it is also very convenient to install after cleaning; the bullet ejection shaft is used for transmission, one end of the bullet ejection shaft is connected to the motor, and the other end is matched with the bearing of the bullet ejection chassis to achieve the effect of reducing shaking and making the bullet ejection smoother; the motor is placed inside the magazine and protected by the motor housing to avoid the motor being exposed to the outside and being damaged by external impacts, etc., and the overall mechanism is more concise, without redundant protruding parts, and is convenient to be placed in different occasions.

The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

Example 1

As shown in Figures 1-7, an embodiment of a spherical material storage and output device with a detachable chassis is shown, including a magazine 1 for placing materials, a chassis 2 provided with an ejection outlet 201, a motor 3 and a ejector wheel 4 connected to the motor 3 and extending into the chassis 2, the chassis 2 is provided with a positioning groove, the magazine 1 is provided with two opposite openings, and one of the openings faces the chassis 2 and cooperates with the positioning groove 202; the magazine 1 is detachably connected to the chassis 2; the motor 3 is installed in the magazine 1.

Specifically, the magazine 1 is detachably connected to the chassis 2 via a lock 5. The lock 5 enables quick installation and removal of the chassis 2 and the magazine 1, and the connection of the lock 5 is more durable.

Preferably, the magazine 1 is provided with a cantilever beam 101 for mounting the motor 3, and the cantilever beam 101 is provided with a motor housing 102 for wrapping the motor 3. The motor 3 can be completely placed in the motor housing 102, so that the motor 3 is not exposed inside the device, and the geometric shape of the device is more regular and protects the motor.

As shown in Fig. 2-3, the motor 3 is connected to the ejector wheel 4 via the ejector shaft 6; the ejector wheel 4 is provided with a through hole 401, and the ejector shaft 6 passes through the through hole 401 and is detachably connected to the ejector wheel 4; one end of the ejector shaft 6 is connected to the motor 3, and the other end is rotatably connected to the chassis 2. The ejector wheel 4 is connected to the ejector shaft 6 so that the ejector wheel 4 is no longer suspended in the air, and is more stable when working, reducing the radial vibration of the ejector shaft 6 and the periodic shear stress fluctuation of the ejector wheel 4 caused by it, and significantly improving the output stability and service life of the output device.

Specifically, the ejector wheel 4 is provided with two mounting holes 402 located in different planes, and the axes thereof are perpendicular to each other; the ejector shaft 6 is provided with a fixing hole 601 matched with the mounting hole 402; one end of the ejector shaft 6 is connected to the output shaft of the motor 3 through a shaft cylinder 602, and the other end is rotatably connected to the chassis 2 through a bearing. The mounting hole 402 of the ejector wheel 4 and the fixing hole 601 of the ejector shaft 6 are connected by inserting a fixing member, which can ensure the transmission of the ejector shaft 6 and the ejector wheel 4, and can prevent the ejector wheel 4 from radially deviating.

Among them, the driving teeth 404 of the ejection wheel 4 are gear-type. The ejection wheel 4 adopts the gear-type driving teeth 404, and has a gear involute, so that the spherical material can continue to be subjected to the main force in the same direction. Regardless of whether the spherical material is in the process of moving on a circular trajectory or leaving the circular trajectory and entering the ejection outlet 201, the gear involute can ensure that the main force of the ejection wheel 4 on the spherical material is in the same direction, which effectively reduces the extrusion between the spherical material and the side wall, and minimizes the possible sliding friction of the spherical material.

In addition, a conical truncated cone 403 is provided on one side of the ejector wheel 4 close to the motor 3. The conical truncated cone 403 is used to guide the trajectory of the spherical material in the ejector chassis 2, so that it flows into the tooth groove of the ejector wheel 4, and prevents the spherical material from accumulating or pausing without entering the chassis 2.

As shown in Figures 4-6, the chassis 2 is provided with a trajectory 203 for placing spherical materials, and the trajectory 203 is connected to the ejection outlet 201, and the trajectory 203 is provided with a spiral slope. The chassis 2 provided with a spiral slope can make better use of the mass properties of the material itself, and a spiral ramp is added to the bottom of the ejection plate. Relying on a certain slope, the material can slide down along the spiral slope with the help of its own gravitational potential energy, reducing the pressure demand for the power output of the ejection wheel 4. Once a jam occurs, the ejection wheel 4 can be reversed to achieve ejection, and the material can climb with the help of the spiral slope, which can solve the ejection and jam problems as much as possible.

In addition, the connection between the ballistic trajectory 203 and the ejection outlet 201 is rounded, and the protruding edges are removed, eliminating the original side wall angle being low, and there will be a jam between the top of the output interface and the ejection wheel 4, and the risk that the spherical material may not be pushed into the ejection outlet and get stuck between the ejection wheel 4 and the straight wall when the ejection wheel 4 rotates at a high speed. The ejection outlet 201 is provided with a preset device 204, which is an elastically pressed switch, in order to be able to timely know the ejection flow rate passing through the ejection outlet or the pipeline outlet and whether the ejection is continuous in actual use, which ensures that the relevant parameters can be fed back in time.

The working principle or workflow of this embodiment is as follows: the magazine 1 is a cavity with only four side panels, which can be formed by connecting the four side panels through angle brackets. The positioning grooves 202 are set around the chassis 2, and the side panels are inserted into the positioning grooves 202 to limit the horizontal freedom of the magazine 1. The chassis 2 and the magazine 1 are detachably connected by means of a snap connection and a lock 5 connection to ensure vertical constraints. When it is necessary to clean materials or replace accessories, the chassis 2 and the magazine 1 can be directly disassembled, and the materials in the magazine 1 can be directly dumped out.

Under normal use, a spherical material is placed in the magazine 1. The material falls into the trajectory of the chassis 2 due to gravity and flows downward along the trajectory to between the pushing teeth 404 of the middle ejector wheel 4. The motor 3 drives the ejector shaft 6 to rotate, thereby driving the ejector wheel 4 to rotate. At the same time, the spherical material will be constrained by the bottom curved surface of the chassis, so that the spherical material can move more smoothly. When the ejector wheel 4 rotates, the spherical material is pushed out of the chassis 2 from the ejection outlet 201.

Beneficial effects of this embodiment: The chassis and magazine of this device can be quickly disassembled, and the chassis can be quickly and conveniently replaced or cleaned. When cleaning and maintenance are required, the chassis can be easily removed by simply opening the buckle. After cleaning, installation is also very convenient; the ejection shaft 6 is used for transmission, one end of the ejection shaft 6 is connected to the motor, and the other end is matched with the bearing of the ejection chassis to achieve the effect of reducing shaking and making the ejection smoother; the motor is placed inside the magazine and protected by a motor housing to prevent the motor from being exposed to the outside and possibly damaged by external impacts, and also makes the overall mechanism more concise, without redundant protruding parts, and convenient for placement in different occasions.

Example 2

Figures 8-10 show another embodiment of a new type of detachable chassis 2 for storing and outputting small-sized spherical materials. The difference from the embodiment 1 is that, specifically, the side wall of the ballistic trajectory 203 is arc-shaped, and the radius of the arc is the radius of the ejected material. If there are too many spherical materials (output objects) piled up on the chassis 2, the spherical materials leaning against the side wall can be squeezed upward along the spherical side wall by the ejection wheel 4, which is equivalent to turning over the materials in the chassis 2. Moreover, since there is a larger movement space when pushing upward on the arc surface than on the cylindrical side wall, the risk of the material being stuck between the side wall and the ejection wheel 4 is effectively reduced. At the same time, due to the effect of the arc surface, the gravity of the upper material is no longer directly superimposed on the lower material, but is subject to the effect of a gravity component parallel to the arc surface, and the component is smaller as the distance to the bottom increases. When the ejection wheel 4 ejects the material, the influence of other materials accumulated in the ejection chassis 2 on the material trajectory and force in the track can be effectively reduced. In terms of the orbit of the spherical material's rotational motion, the chassis 2 uses a spiral gradually deepening depression on the arc surface that passes through the material output port as the spherical material orbit of the bullet-pulling chassis 2. The inclination tangent value of the spiral orbit is less than the friction coefficient between the material and the bullet-pulling chassis 2, so as to minimize friction loss. Finally, the spiral orbit is stably connected to the material input port to ensure the continuity and stability of the entire bullet-pulling process, effectively increasing the guiding efficiency of the spherical material.

The remaining features and working principles of this embodiment are consistent with those of Embodiment 1.

Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
