Technical Field

[0001] This utility model relates to the field of high-density plywood production technology, specifically to a pressing device for high-density plywood production. Background Technology

[0002] High-density fiberboard (HDF) is a type of board material, classified by density into low-density, medium-density, and high-density; and by raw materials into fiberboard, plywood, particleboard, etc. High-density plywood (HDP) is a type of HDF, and edge-pressing devices are required during its production.

[0003] In existing technologies, when pressing edges of high-density plywood, the pressing angle needs to be adjusted to prevent edge cracking and chipping. However, adjusting the pressing angle is cumbersome and inconvenient, affecting pressing efficiency. Therefore, a pressing device for high-density plywood production is needed to solve these problems. Utility Model Content

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1 As shown, this utility model provides a technical solution: a pressing device for high-density plywood production, comprising:

[0027] A base plate 1 for placing high-density plywood has a pair of drive cylinders 2 symmetrically arranged on opposite side walls of the base plate 1. A connecting seat 3 is provided on the top of the sliding block of each pair of drive cylinders 2. A guide post 7 is rotatably arranged between the pair of connecting seats 3. A pair of mounting plates 5 are provided on the side wall of the guide post 7. A pressure roller 6 for pressing the edge of the high-density plywood is rotatably arranged on the side wall of each pair of mounting plates 5.

[0028] The guide post 7 has an arc-shaped locking plate 10 on its side wall, and the connecting seat 3 has a locking assembly 12 on its side wall for applying force to the arc-shaped locking plate 10 to prevent the guide post 7 from rotating. This design rotates the guide post 7 by applying force to the mounting plate 5, which in turn rotates the pressure roller 6 on the mounting plate 5. When the pressure roller 6 contacts the top of the high-density plywood, the force applied to the mounting plate 5 stops. Then, the locking assembly 12 applies force to the arc-shaped locking plate 10 to prevent the guide post 7 from rotating, thus preventing changes in the position of the pressure roller 6 and facilitating adjustment of the pressing angle, thereby improving pressing efficiency. When pressing the high-density plywood, a pair of drive cylinders 2 move the connecting seat 3, which in turn moves the mounting plate 5 on the guide post 7. The movement of the mounting plate 5 then causes the pressure roller 6 to press the high-density plywood.

[0029] Reference Figure 1 and Figure 2 The locking assembly 12 includes a fixing plate 124 disposed on the side wall of the connecting seat 3. A locking threaded rod 123, which is connected to the arc-shaped locking plate 10, is provided through the top of the fixing plate 124. A connecting bearing 122 is provided at the connection between the locking threaded rod 123 and the arc-shaped locking plate 10. A pair of limiting posts 121, which penetrate the fixing plate 124 and are located on both sides of the locking threaded rod 123, are symmetrically arranged on the top of the arc-shaped locking plate 10. This design, through the threaded connection between the locking threaded rod 123 and the fixing plate 124 in the locking assembly 12, facilitates the tight fit between the arc-shaped locking plate 10 and the side wall of the guide post 7 to stop the guide post 7, thereby improving the stability of the high-density plywood edge pressing.

[0030] Reference Figure 2 and Figure 5 The guide post 7 has an annular groove 72 on its side wall, and the arc-shaped locking plate 10 matches the annular groove 72. This design facilitates the fitting of the arc-shaped locking plate 10 with the inner wall of the annular groove 72 through the annular groove 72, thereby improving the stability of the connection between the guide post 7 and the arc-shaped locking plate 10.

[0031] Reference Figure 2 Each pair of connecting seats 3 has a connecting plate 13 on one side wall that is close to each other, and a mounting bearing 11 is provided between the guide post 7 and the connecting plate 13. This design improves the stability of the guide post 7 driving the pressure roller 6 to rotate through the connecting plate 13 and the mounting bearing 11, facilitates the adjustment of the pressing angle by the rotation of the pressure roller 6, and improves the pressing efficiency.

[0032] Reference Figure 3 , Figure 4 and Figure 5 The connecting seat 3 has a sliding groove 31 on its side wall that matches the connecting plate 13. An adjusting electric push rod 4 connected to the connecting plate 13 is located on the top of the connecting seat 3. The fixing plate 124 is located on the side wall of the connecting plate 13. This design allows the connecting plate 13 to move vertically along the sliding groove 31 by adjusting the electric push rod 4. The movement of the connecting plate 13 causes the guide column 7 to move vertically, facilitating the adjustment of the pressure roller 6's height and improving the pressing efficiency.

[0033] Reference Figure 2 and Figure 3The mounting plate 5 has a through hole 51 on its side wall that matches the side wall of the guide post 7. The guide post 7 has a stop groove 71 on its top, and a stop post 8 is installed inside the stop groove 71. The top of the mounting plate 5 is provided with a stop assembly 9 for applying force to the stop post 8 to fit into the stop groove 71 to stop the mounting plate 5. This design allows the stop post 8 to move along the stop groove 71, facilitating the adjustment of the position of the mounting plate 5 on the side wall of the guide post 7. The position of the pressure roller 6 can be adjusted to press the edges of high-density plywood of different lengths. The stop assembly 9 fixes the position of the pressure roller 6 to prevent displacement. The stop post 8 connected along the stop groove 71 prevents the mounting plate 5 from sliding sideways along the guide post 7.

[0034] Reference Figure 5 and Figure 6 The stop assembly 9 includes a stop threaded rod 91 disposed on the top of the mounting plate 5 and connected to the stop post 8. A connecting bearing 92 is provided at the connection between the stop threaded rod 91 and the stop post 8. This design facilitates the stop threaded rod 91 to drive the stop post 8 to fit tightly against the stop groove 71 to stop the mounting plate 5 through a threaded connection with the mounting plate 5.

[0035] Reference Figure 5 A rotating bearing 61 is provided between the mounting plate 5 and the pressure roller 6, which improves the rationality of the design.

[0036] Reference Figures 1-6 As an embodiment of this utility model: when it is necessary to adjust the pressing angle of the high-density plywood, the worker applies force to the mounting plate 5 to drive the guide column 7 to rotate. The rotation of the guide column 7 drives the pressure roller 6 on the mounting plate 5 to rotate. When the pressure roller 6 contacts the top of the high-density plywood, the force applied to the mounting plate 5 is stopped. Then, the locking assembly 12 applies force to the arc-shaped locking plate 10 to stop the rotation of the guide column 7, so as to prevent the position of the pressure roller 6 from changing, which facilitates the adjustment of the pressing angle and improves the pressing efficiency.

[0037] By adjusting the operation of the electric push rod 4, the connecting plate 13 moves vertically along the sliding groove 31. The movement of the connecting plate 13 causes the guide column 7 to move vertically, which facilitates the adjustment of the height of the pressure roller 6 and the adjustment of the pressing height. With the rotation of the pressure roller 6, the pressure roller 6 can be adjusted to a suitable pressing angle to adapt to high-density plywood of different thicknesses and improve the pressing efficiency.

[0038] After the pressing angle is adjusted, a pair of drive cylinders 2 drive the connecting seat 3 to move. The connecting seat 3 drives the mounting plate 5 on the guide column 7 to move. The movement of the mounting plate 5 drives the pressing roller 6 to perform pressing operation on the high-density wood board, which improves the practicality of this utility model.
