During the processing, a hot pressing device is needed to perform a hot pressing process on the boards and the cover paper, which can form the boards and the cover paper into one piece, making it easier to make them into musical instrument soundboards later.

[0003] The existing hot pressing device for processing musical instrument plates is also very prone to high plate damage rate during use, which reduces the problem of hot pressing quality of the plates;

[0004] The reason for this problem is that in the process of hot pressing the board, it is necessary to coat the surface of the board body with glue, and then lay the cover paper to be processed on the top of the board, and then place the board on the top of the upper pressing plate of the hot pressing device, and use the upper pressing plate and the lower pressing plate to hot press the board. During the hot pressing process of the lower pressing plate, there is no equipment to tightly fit the board and the cover paper. In this way, when the upper pressing plate is pressed down to hot press the board, bubbles may appear on the surface of the cover paper, thereby reducing the quality of the hot pressing of the board.
