Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] refer to Figure 1-4 The diagram shows a pressing device for producing polyurethane boards, including a workbench 1. The workbench 1 provides a stable working platform for the entire pressing device. A cleaning component is installed on the top of the workbench 1, which cleans the polyurethane boards, improves their surface quality, and provides favorable conditions for subsequent processing steps. The cleaning component includes a support base 16 fixedly connected to the bottom of the workbench 1. A first electric push rod 4 is fixedly connected to the top of the support base 16. The output end of the first electric push rod 4 passes through the workbench 1, and a first clamping plate 15 is fixedly connected to the output end of the first electric push rod 4. A brush 24 is installed at the bottom of the first clamping plate 15. A placement groove 3 adapted to the brush 24 is provided on the top of the workbench 1. The placement groove 3 provides space for storing and placing the brush 24 when it is not in use, allowing the brush 24 to be hidden inside the workbench 1 without affecting the normal operation of other components above the workbench 1, while also providing some protection for the brush 24.

[0025] The support base 16 provides stable support for the first electric push rod 4, ensuring its stability during operation and preventing it from shaking or shifting. The first electric push rod 4 can move its output end connected components up and down through telescopic movement, achieving precise control over the positions of the first clamping plate 15 and the brush 24. The first clamping plate 15 is used to fix and install the brush 24, ensuring its accurate positioning during operation and transmitting power from the first electric push rod 4 to the brush 24, enabling it to perform cleaning smoothly. Driven by the first electric push rod 4, the brush 24 cleans the surface of the polyurethane board, removing impurities and debris, improving the surface smoothness and cleanliness of the polyurethane board, and preventing impurities from affecting subsequent processing and use.

[0026] A second clamping plate 26 is fixedly connected to the top of the workbench 1. A second electric push rod 10 is fixedly connected to the side wall of the second clamping plate 26. The second electric push rod 10 can move through extension and retraction. The output end of the second electric push rod 10 passes through the second clamping plate 26. A push plate 13 is fixedly connected to the output end of the second electric push rod 10. Driven by the second electric push rod 10, the push plate 13 can directly act on the polyurethane board to push, squeeze and perform other operations, thereby adjusting the position and state of the polyurethane board to meet different processing requirements.

[0027] The second clamping plate 26 is used to install and support the push plate 13, providing a stable starting position for the movement of the push plate 13, ensuring that the push plate 13 can maintain a stable direction and position during operation, providing power to the push plate 13 so that it can move in the direction of the second clamping plate 26, and can be used to push or adjust the position of the polyurethane plate.

[0028] The top of the workbench 1 is provided with a third clamping plate 14 and a fourth clamping plate 17, which are used to clamp and fix the polyurethane board. By moving them, the clamping position and force of the polyurethane board can be adjusted to ensure that the polyurethane board remains stable during processing and does not shift. The workbench 1 is provided with a first moving groove 8 and a second moving groove 9. The first moving groove 8 and the second moving groove 9 provide moving tracks for the first connecting block 12 and the second connecting block 18, ensuring that the third clamping plate 14 and the fourth clamping plate 17 can move linearly along a predetermined direction, thereby improving the stability and accuracy of the movement.

[0029] The bottom of the third clamping plate 14 is fixedly connected to the first connecting block 12. The first connecting block 12 is fixedly connected to the third clamping plate 14 and slides inside the second moving groove 9, which serves to connect the third clamping plate 14 and the worktable 1, so that the third clamping plate 14 can move on the worktable 1, and at the same time restricts the movement direction of the third clamping plate 14. One end of the first connecting block 12 is fixedly connected to the first rack 11.

[0030] A motor 20 is fixedly connected to the top of the workbench 1, serving as the power source. The output end of the motor 20 passes through the workbench 1, and a gear 21 is fixedly connected to the output end of the motor 20. The gear 21 rotates under the drive of the motor 20, and the first rack 11 meshes with the gear 21. Through meshing with the first rack 11 and the second rack 19, the rotational motion of the motor 20 is converted into the linear motion of the third clamping plate 14 and the fourth clamping plate 17, achieving precise control of the position of these two clamping plates. When the gear 21 rotates, through interaction with the gear 21, the first connecting block 12 and the third clamping plate 14 are moved, thereby adjusting the clamping position of one side of the polyurethane board.

[0031] A second connecting block 18 is fixedly connected to the bottom of the fourth clamping plate 17. A second rack 19 is fixedly connected to one end of the second connecting block 18. The second rack 19 meshes with the gear 21.

[0032] The second connecting block 18 is fixedly connected to the fourth clamping plate 17 and slides inside the first moving groove 8, serving to connect the fourth clamping plate 17 and the worktable 1, allowing the fourth clamping plate 17 to move on the worktable 1, while also restricting the direction of movement of the fourth clamping plate 17. When the gear 21 rotates, the second connecting block 18 and the fourth clamping plate 17 move through interaction with the gear 21, thereby adjusting the clamping position on the other side of the polyurethane board. The first rack 11 and the second rack 19 both mesh with the gear 21. Through the meshing transmission between the gear 21 and the first rack 11 and the second rack 19, the movement of the third clamping plate 14 and the fourth clamping plate 17 is realized, thereby enabling precise clamping and fixing of the polyurethane board as needed.

[0033] Both sides of the second clamping plate 26 are provided with locking blocks 25. The side walls of the third clamping plate 14 and the fourth clamping plate 17 are provided with locking slots 22 that are adapted to the locking blocks 25. The locking blocks 25 are used to cooperate with the locking slots 22 on the third clamping plate 14 and the fourth clamping plate 17. When the third clamping plate 14 and the fourth clamping plate 17 are moved to the appropriate position, the locking blocks 25 can be inserted into the locking slots 22 to fix the third clamping plate 14 and the fourth clamping plate 17 and prevent them from shifting during processing. The locking slots 22 cooperate with the locking blocks 25 to provide fixing points for the third clamping plate 14 and the fourth clamping plate 17 and ensure their stability during operation.

[0034] One end of the third clamping plate 14 is fixedly connected to a clamping plate 23, and one end of the first clamping plate 15 is provided with a sliding groove that matches the clamping plate 23. The sliding groove provides moving space for the clamping plate 23. The clamping plate 23 cooperates with the sliding groove on the first clamping plate 15. When the first clamping plate 15 moves, the clamping plate 23 can slide in the sliding groove, which plays a role in restricting and guiding the moving direction of the first clamping plate 15. At the same time, it can also enhance the connection stability between the first clamping plate 15 and the third clamping plate 14 to a certain extent. This allows the first clamping plate 15 and the third clamping plate 14 to move relative to each other while maintaining a certain connection relationship, ensuring that the first clamping plate 15 and the third clamping plate 14 can work together during cleaning and other operations.

[0035] Two pairs of support legs 2 are fixedly connected to the bottom of the workbench 1. The support legs 2 are used to support the workbench 1 and keep it at a certain distance from the ground, providing stable support for the workbench 1, ensuring the stability of the entire device during operation, and preventing it from tilting or shaking.

[0036] A housing 7 is fixedly connected to the top of the workbench 1. A telescopic cylinder 6 is fixedly connected to the top of the housing 7. A pressure plate 5 is fixedly connected to the output end of the telescopic cylinder 6. The telescopic cylinder 6 can move the pressure plate 5 up and down through its telescopic movement. Driven by the telescopic cylinder 6, the pressure plate 5 can evenly press the polyurethane board, allowing the polyurethane board to be better shaped under pressure, meeting the production process requirements for the density and flatness of the polyurethane board, and ensuring that the polyurethane board does not shift during processing. The housing 7 is used to protect the internal components such as the telescopic cylinder 6 and the pressure plate 5, preventing dust, debris, etc. from entering and affecting the normal operation of the components. It also plays a role in protecting the safety of operators to a certain extent.

[0037] The working principle of this device is as follows: When using this device, the operator first places one end of the polyurethane board to be formed against the first clamping plate 26. The motor 20 is started to drive the gear 21 to rotate. The gear 21 meshes with the first rack 11 and the second rack 19, causing the first connecting block 12 and the second connecting block 18 to move along the first moving groove 8 and the second moving groove 9, respectively. This causes the second clamping plate 14 and the fourth clamping plate 17 to fix the left and right ends of the polyurethane board, respectively. Then, the first electric push rod 4 causes the third clamping plate 15 to fall along the clamping plate 23. The telescopic cylinder 6 is started to repeatedly press down the pressing plate 5 to complete the forming of the polyurethane board. After the forming is completed, the second electric push rod 10 is started, and the forming polyurethane board is detached through the push plate 13. The pressed surface is then cleaned with a brush 24.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
