Abstract
Description
Technical Field
[0001] This utility model relates to the field of plywood processing technology, and specifically to a sanding device for plywood processing and production. Background Technology
[0002] With the continuous development of the furniture industry, plywood has become one of the most commonly used materials in the furniture industry. Because plywood can be made into various patterns and textures according to market demand, it has always been favored by the furniture market. During the production process of plywood, burrs are easily generated on the surface of the plywood. Before sales and packaging, the burrs on the surface must be removed. At present, most sanding devices on the market can only remove the burrs on one side of the plywood first, and then flip the board to remove the burrs on the other side. Sanding devices that can sand burrs on multiple sides occupy a large area and have a high cost, and are only suitable for large-scale production.
[0003] A search revealed that CN218312565U discloses a sanding device for plywood processing, which facilitates sanding. The device includes a motor housing, a clamping device installed on the right side of the motor housing, a top plate installed above the clamping device, support legs installed at the four corners of the lower end face of the top plate, a base installed below the support legs, a controller installed on the support legs, a sanding device installed on the lower end face of the top plate, and a size adjustment device installed on the right side of the support legs. This utility model discloses a convenient plywood processing and production grinding device. By incorporating a clamping device and a motor housing, the upper and lower jaws clamp the plywood and fix it to the clamping device. The motor housing, through motor rotation, drives the main shaft, which in turn drives the clamping device. This achieves multi-faceted deburring of plywood while also reducing costs and space requirements. However, its drawback is that during grinding, the plywood is suspended in mid-air, with the top of the plywood contacting the grinding wheel and applying pressure. The lack of support at the bottom causes deformation, affecting the plywood's usability. Therefore, improving existing grinding devices and designing a new type of plywood processing and production grinding device to address these technical shortcomings and improve overall practicality is of paramount importance.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0024] Example:
[0025] Please see Figures 1-6 This utility model provides a technical solution:
[0026] A sanding device for plywood processing includes a sanding table body 1, a movable shell 2 slidably connected to the top of the sanding table body 1, a support component 3 inside the movable shell 2, a flipping component 4 on the top of the sanding table body 1 and above the movable shell 2, a sanding disc 5 on the top of the sanding table body 1 and above the flipping component 4, and multiple sets of through holes 6 on the top of the sanding table body 1 and outside the movable shell 2. A negative pressure pump is installed inside the sanding table body 1. When sanding plywood, the negative pressure pump is activated in conjunction with the through holes 6 to guide the sawdust generated during sanding into the interior of the sanding table body 1 for collection, preventing sawdust from spreading and affecting the working environment.
[0027] The support assembly 3 is used to support the plywood. The support assembly 3 consists of a rotating disk 7, a moving rod 8, a moving block 9, a support block 10, a pressing rod 11, and a screw 12. The rotating disk 7 is rotatably connected to the inside of the movable shell 2. Multiple sets of moving rods 8 are located at the bottom of the rotating disk 7 and are slidably connected to the inside of the movable shell 2. The moving block 9 is fixedly connected to the end of the moving rod 8 away from the rotating disk 7. The support block 10 is fixedly connected to the end of the moving block 9 that extends to the outside of the movable shell 2. The pressing rod 11 is slidably connected to the top of the movable shell 2. The screw 12 is located at the bottom of the pressing rod 11 and is fixedly connected to the rotating disk 7.
[0028] Furthermore, the drive end of the first telescopic cylinder is fixedly connected inside the movable shell 2. The first telescopic cylinder is fixedly installed inside the grinding table body 1. When the first telescopic cylinder is activated, the movable shell 2 is moved so that the pressing rod 11 can contact the plywood.
[0029] The rotating disk 7 has an arc-shaped groove 13 inside. The moving rod 8 extends into the arc-shaped groove 13 and is fixedly connected to a guide rod. The guide rod and the arc-shaped groove 13 are slidably connected. When the rotating disk 7 rotates, it drives the arc-shaped groove 13 to move, which in turn drives the guide rod inside to move, which in turn drives the moving rod 8 to move, which in turn drives the moving block 9 to move, which in turn drives the support block 10 to move, thus expanding the multiple sets of support blocks 10 to support the plywood.
[0030] Secondly, a connecting seat 14 is fixedly connected inside the movable shell 2 and outside the pressing rod 11. The pressing rod 11 and the connecting seat 14 are slidably connected. A sliding rod 15 is fixedly connected inside the connecting seat 14. The pressing rod 11 and the sliding rod 15 are slidably connected. A return spring 16 is sleeved on the outside of the sliding rod 15 and at the bottom of the pressing rod 11. When the pressing rod 11 contacts the plywood, it is displaced by a relative force. When the pressing rod 11 is displaced, it can be guided by the sliding rod 15. When the contact between the pressing rod 11 and the plywood is broken, the return spring 16 can drive the pressing rod 11 to return to its original position.
[0031] Furthermore, the inside of the pressing rod 11 is provided with a receiving groove 17, and a guide block 18 is fixedly connected to the bottom of the receiving groove 17. The guide block 18 is in contact with the surface of the screw 12. When the pressing rod 11 is displaced, the screw 12 can contact the receiving groove 17, and at the same time, the guide block 18 is displaced. The guide block 18 can drive the screw 12 to rotate, so that the rotating disk 7 rotates.
[0032] Furthermore, the flipping assembly 4 consists of a connecting frame 19, two sets of movable seats 20, two sets of clamping plates 21, a telescopic rod 22, a second telescopic cylinder 23, and a drive motor 24. The connecting frame 19 is fixedly connected to the inside of the grinding table body 1 and located above the movable shell 2. Both sets of movable seats 20 are slidably connected to the outside of the connecting frame 19. The clamping plates 21 are rotatably connected to the outside of the movable seats 20. The telescopic rod 22 is located between the two sets of clamping plates 21. The second telescopic cylinder 23 is located between the two sets of movable seats 20. The drive motor 24 is fixedly installed on the outside of the connecting frame 19, and the drive end of the drive motor 24 is fixedly connected to the clamping plate 21. The second telescopic cylinder 23 is activated, which drives the two sets of moving seats 20 to move, causing the two sets of clamping plates 21 to move. When the clamping plates 21 move, they can be guided by the telescopic rod 22 to place the plywood between the two sets of clamping plates 21. The two sets of clamping plates 21 move closer to each other, so that the plywood can be clamped and fixed. The grinding disc 5 can be used to grind the plywood. When one side of the plywood is ground, the drive motor 24 is activated, which drives the clamping plate 21 to rotate. The telescopic rod 22 drives the other set of clamping plates 21 to rotate, so that the clamped plywood can be flipped over to grind the other side.
[0033] In this embodiment, the specific implementation scenario is as follows: In actual use, the second telescopic cylinder 23 is activated, causing the two sets of movable seats 20 to move, which in turn causes the two sets of clamping plates 21 to move. When the clamping plates 21 move, they are guided by the telescopic rod 22, placing the plywood between the two sets of clamping plates 21. The two sets of clamping plates 21 move closer to each other, clamping and fixing the plywood. The first telescopic cylinder is activated, causing the movable shell 2 to move, allowing the pressing rod 11 to contact the plywood. When the pressing rod 11 contacts the plywood, it is displaced by a relative force. When the pressing rod 11 moves, the screw 12 contacts the receiving groove 17, and at the same time, it causes the guide block 18 to move. The guide block 18 causes the screw 12 to rotate, causing the rotating disk 7 to rotate. When the rotating disk 7 rotates, it drives the arc-shaped groove 1... 3. Displacement is performed, causing the internal guide rod to move, which in turn moves the moving rod 8, causing the moving block 9 to move, which in turn moves the support block 10, expanding the multiple sets of support blocks 10 to support the plywood and prevent deformation of the plywood during sanding, thus affecting its use. When sanding the plywood, the negative pressure pump is activated, and the through hole 6 is used to guide the sawdust generated during sanding into the interior of the sanding table body 1 for collection, preventing sawdust from spreading and affecting the working environment. When one side of the plywood is sanded, the moving shell 2 is reset, the drive motor 24 is activated, and the clamping plate 21 is rotated. Through the telescopic rod 22, another set of clamping plates 21 is rotated, allowing the clamped plywood to be flipped over for sanding the other side. Compared with existing sanding devices, this utility model improves the overall practicality of the sanding device through its design.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
