One end of the torsion spring 10 is fixedly connected to the round block 6, and the other end is fixedly connected to the stop block 9. A gear 23 is installed on the outer surface of the rotating rod 7. A hot press plate 11 is set above the front placement frame 8. A hydraulic cylinder 12 is installed on the upper end of the hot press plate 11. A support frame 13 is installed on the upper end of the hydraulic cylinder 12, and the support frame 13 is fixedly connected to the base plate 1. A hollow box 14 is set above the round block 6, and the hollow box 14 is fixedly connected to the support frame 13. A fan 15 is installed inside the hollow box 14. Connecting pipes 16 are symmetrically installed at both ends. A discharge hood 17 is installed at one end of the left connecting pipe 16, and a extraction hood 18 is installed at one end of the right connecting pipe 16. The discharge hood 17 and the extraction hood 18 are respectively located above the two placement frames 8. A collection frame 19 is set below the rear placement frame 8 and is placed on the upper end of the base plate 1. An arc-shaped support plate 20 is set on the upper end of the base plate 1, and the upper end surface of the arc-shaped support plate 20 slides in fit with the lower end surface of the placement frame 8. Several support rods 22 are installed on the lower end of the arc-shaped support plate 20 and are fixed to the base plate 1. At the upper end, a notch 21 is provided at the rear of the arc-shaped support plate 20, and the notch 21 is located directly above the collection frame 19. A lifting mechanism 24 is installed at the rear end of the hollow box 14. The lifting mechanism 24 includes a grooved rod 25 and a threaded rod 26. The grooved rod 25 is rotatably connected to the threaded rod 26. A motor 27 is installed at the upper end of the threaded rod 26. A threaded sleeve 28 is fitted on the outer surface of the threaded rod 26. A fixing block is installed at the rear end of the threaded sleeve 28. A vertical rod 29 is installed at the lower end of the fixing block. A straight rack 30 is installed at the lower end of the vertical rod 29, and the straight rack 30 corresponds to the position of the gear 23.

[0021] The working principle of this utility model is as follows: The board is placed into the rear placement frame 8. Then, the motor 5 drives the rotating shaft 2 to rotate 90 degrees intermittently through the bevel gear 4 and bevel gear 3. The rotating shaft 2 drives the placement frame 8 to rotate 90 degrees through the round block 6 and the rotating rod 7. The placement frame 8 slides on the upper end of the arc-shaped support plate 20, so that the placement frame 8 drives the board to move to the bottom of the hot press plate 11. The hydraulic cylinder 12 drives the hot press plate 11 to descend and perform hot pressing on the board. The arc-shaped support plate 20 provides support for the placement frame 8. Then, the placement frame 8 continues to rotate intermittently, so that the hot-pressed board moves to the right side and the unpressed board moves to the left side. The worker continues to load the material on the rear side, and the front side performs hot pressing through the hot press plate 11.

[0022] At the same time, the fan 15 generates suction, which is used to cool the hot-pressed board through the right connecting pipe 16 and the extraction hood 18. Meanwhile, the fan 15 blows the extracted heat energy through the left connecting pipe 16 and the exhaust hood 17 onto the board that has not undergone hot pressing, preheating the board and improving the hot pressing efficiency. At the same time, it effectively utilizes the heat of the hot-pressed board to achieve energy saving.

[0023] When the hot-pressed sheet material is rotated to the top of the collection frame 19, motor 27 drives the threaded sleeve 28 to descend via the threaded rod 26. The threaded sleeve 28 drives the rack 30 to descend via the fixed block and the upright rod 29. The rack 30 descends and meshes with the rear gear 23, causing the rack 30 to push the rear gear 23 to rotate 180 degrees. The gear 23 drives the placement frame 8 to flip over via the rotating rod 7, causing the sheet material to fall into the collection frame 19 under the influence of gravity, thus achieving automatic unloading. When the rotating rod 7 rotates, the torsion spring 10 is torsionally deformed by the stop block 9. After unloading is completed, motor 27 reverses and drives the rack 30 to rise. The rack 30 meshes with the gear 23, causing the gear 23 to drive the placement frame 8 to rotate and reset. At the same time, the torsion spring 10 torsionally reset assists in the rotation and reset of the placement frame 8. Then, the staff continues to place sheet material in the placement frame 8.
