[0002] In the field of modern panel solid wood custom furniture, "polymer film-faced solid wood boards" are formed by covering the surface of solid wood boards with PVC or PP polymer film finishing materials, and the production of "polymer film-faced solid wood boards" requires the use of pressing equipment.

[0003] For example, Chinese patent CN111469224A discloses an ultra-thin polymer film-faced solid wood board and its manufacturing method; Chinese patent CN205766626U discloses a stable bamboo plywood hot press.

[0004] However, the above structure has the following problems: the waterproof performance of the above-mentioned boards is not ideal, and they are prone to moisture and deformation after long-term use. At the same time, the wear resistance is not designed, and wear will also occur after long-term use. In addition, the existing pressing equipment is not convenient for synchronous loading and unloading, and hot air is not convenient for continuous use.

[0005] Based on this, the present invention designs a thin polymer film-faced solid wood board, its molding method and pressing equipment to solve the above problems. Summary of the Invention

[0075] Example 4

[0076] Please refer to the instruction manual appendix. Figure 2-12 A pressing device for forming a thin polymer film-faced solid wood board includes a multi-layer hot pressing assembly 1.

[0077] The multi-layer hot pressing assembly 1 includes a hot pressing assembly and a circulation assembly, and the hot pressing assembly is connected to the circulation assembly;

[0078] A batch feeding component 2 is connected to the feeding end of the hot pressing component. The batch feeding component 2 includes a translation component 21, a receiving component 22, a support frame 23, and a movable baffle component 24. The top of the support frame 23 is connected to the translation component 21, the driving end of the translation component 21 is connected to the receiving component 22, and the discharge end of the support frame 23 is connected at equal intervals with movable baffle components 24 for blocking the return material.

[0079] When the hot pressing component of the multi-layer hot pressing assembly 1 is opened, the receiving component 22 of the batch feeding assembly 2 moves to the bottom. The feeding assembly and the receiving component 22 work together to feed the pre-pressed plates one by one into the receiving component 22. After the receiving component 22 is full, the translation assembly 21 pushes the receiving component 22 into the hot pressing assembly, pushing the hot-pressed plates out of the hot pressing assembly. The translation assembly 21 then drives the receiving component 22 to retract. When the receiving component 22 retracts, the movable baffle assembly 24 pushes the pre-pressed plates on the receiving component 22 into the hot pressing assembly. The translation assembly 21 then pushes the receiving component 22 into the hot pressing assembly.

The top pressure plate 17 and the bottom pressure plate 114 are provided with multiple sets of intermediate pressure plates 113. Each of the top pressure plate 17, intermediate pressure plates 113, and bottom pressure plate 114 has a serpentine channel 111, with both ends of the serpentine channel 111 fixedly connected... A connecting pipe 15 is connected, and a collar 14 is fixedly connected to the outer end of the connecting pipe 15. A first L-shaped plate 13 is symmetrically fixedly connected to the front and rear ends of the bottom pressure plate 114 and the middle pressure plate 113. A second L-shaped plate 16 is symmetrically fixedly connected to the front and rear ends of the middle pressure plate 113 and the top pressure plate 17. The adjacent first L-shaped plates 13 and second L-shaped plates 16 interlock with each other. The collar 14 connected to the middle pressure plate 113 and the collar 14 connected to the bottom pressure plate 114 are in close sliding connection with the circulation component.

[0082] After the pre-press plate moves onto the bottom pressure plate 114 and the middle pressure plate 113 of the multi-layer hot pressing assembly 1, the hydraulic press 19 pushes the upper end of the bottom pressure plate 114 to move, and the bottom pressure plate 114 pushes the middle pressure plate 113 to move upward. The bottom pressure plate 114, the middle pressure plate 113, and the top pressure plate 17 cooperate to press together. During the pressing, the connecting pipe 15 is connected to the air inlet pipe 12 and the air outlet pipe 18 through the air hole 112. The electric hot air blower 110 heats the hot air and circulates it. The circulating air enters the air inlet pipe 12, then enters the connecting pipe 15 through the air hole 112 of the air inlet pipe 12, and then enters the serpentine channel 111 to heat the top pressure plate 17, the middle pressure plate 113, and the bottom pressure plate 114. This process achieves heating and pressing, and then hot air enters the air outlet 18 through the air hole 112 of the air outlet 18, and then enters the electric hot air blower 110 for continued use, realizing recycling. The hot air is free of moisture, which is beneficial for practical use. This process enables synchronous hot pressing of multiple pre-pressed plates. In addition, after pressing, the bottom pressure plate 114 and the middle pressure plate 113 move downwards.

The movable connecting frame 2213 moves downward, causing the uppermost bottom plate 222 to move until it is flush with the feeding assembly. The feeding assembly then sends the pre-pressing plate onto the uppermost bottom plate 222, where the rear baffle 2211 provides a limiting stop. Next, the second motor 226 drives the bottom plate 222 to move upward layer by layer for feeding. After the hot pressing assembly opens, the first motor 214 drives the threaded rod 212 to rotate, which in turn drives the connecting block 213 to rotate. The connecting block 213 then drives the movable top plate 21... 5. The movable top plate 215 moves to the leftmost end, and the pre-pressing plate pushes the rotating baffle 241 of the movable baffle assembly 24 to rotate upward. After the side baffle 221 moves to the rotating baffle 241, the bottom plate 222 pushes the pressed plates on the bottom pressure plate 114, the middle pressure plate 113 and the top pressure plate 17 to be discharged, and the rotating baffle 241 rotates to a vertical position and comes into contact with the blocking block 242. Then, the translation assembly 21 drives the receiving assembly 22 to push to the right, and the rotating baffle 241 removes the pre-pressed plates on the side baffle 221. The pressure plate is pushed down from the side baffle 221 and pushes the pre-pressure plate onto the bottom pressure plate 114, the middle pressure plate 113 and the top pressure plate 17. The translation component 21 then drives the bottom plate 222 to move to the left. The bottom plate 222 then pushes the pre-pressure plate onto the bottom pressure plate 114, the middle pressure plate 113 and the top pressure plate 17. This can completely push the pre-pressure plate into the bottom pressure plate 114, the middle pressure plate 113 and the top pressure plate 17, so as to realize the batch discharge of the formed sheet and the batch loading of the pre-pressure plate, which is beneficial to practical use.
