[0002] During the processing of furniture panels, wooden doors, and various boards, a cold press is usually used to press wood. Traditional cold presses are generally divided into two types: screw type and hydraulic type. The hydraulic type has less noise and more convenient pressure control compared to the screw type, so it is widely used in the production of boards.

[0003] When using a cold press, the board is usually placed on the bearing plate, and then the stamping plate is driven by a hydraulic rod to press the board. During the production and processing of the board, it is necessary for workers to place the board in the working area of the cold press. After processing, it is also necessary for workers to take out the board again. However, when workers take out the board, it is easy to cause injury to the workers. Therefore, a cold press for processing multi-layer boards is proposed. Summary of the Invention

[0085] The working process of this application:

[0086] S1. The staff places the plate to be cold-pressed on the surface of conveyor belt one 801. The height of conveyor belt one 801 is aligned with the height of the lower pressing plate 7 through hydraulic telescopic cylinder one 803. In addition, the plate is conveyed to the surface of the lower pressing plate 7 through conveyor belt one 801.

[0087] S2. The telescopic hydraulic cylinder 4 presses the upper pressing plate 6 against the plate through the reinforcing frame 5. The gears 13 at both ends of the rotating shaft 12 on the surface of the reinforcing frame 5 move on the surface of the rack 11 to achieve the function of stabilizing the reinforcing frame 5. When the limiting plate 1901 is subjected to the pressure of the upper pressing plate 6, it slides on the inner wall of the limiting chute 1903 through the limiting slider 1904 and compresses the first spring 1905. When the limiting plate 2001 is also subjected to the pressure of the upper pressing plate 6, the limiting plate 2001 slides on the inner wall of the limiting chute 2003 through the limiting slider 2004 and squeezes the second spring 2005. After the cold pressing of the plate is completed, the telescopic hydraulic cylinder 4 makes the upper pressing plate 6 reset through the reinforcing frame 5, and the limiting plate 1901 is reset by the first spring 1905. At the same time, the second spring 2005 resets the limiting plate 2001.

[0088] S3. Once again, the electric telescopic rod 25 resets the limiting block 26. The hydraulic telescopic cylinder 803 aligns the height of the push plate 805 with the height of the plate. The electric telescopic rod 804 pushes the plate inward through the push plate 805 to push the plate onto the surface of the conveyor belt 901. The hydraulic telescopic cylinder 903 aligns the height of the conveyor belt 901 with the height of the lower pressing plate 7 to facilitate the transportation of the plate through the conveyor belt 901 and achieve the removal of the plate.
