Description

Polishing device for plates Technical Field The application relates to the technical field of wood processing, in particular to a polishing device for a plate. Background In the wood processing process, in order to improve the smoothness and the aesthetic degree of the surface of the board, it is often necessary to carry out fine polishing treatment on the board surface of the board. At present, the technology commonly adopted in the industry is to polish both sides of a plate at the same time, and although the method improves the efficiency to a certain extent, in some special application scenes, the polishing requirements of customers on both sides of the plate are different, one side may need higher glossiness, and the other side needs coarser texture. In addition, the technique of polishing both sides simultaneously is extremely demanding in terms of equipment, not only requires a high-precision control system, but also has to have strong power and stability, which often makes it difficult to fully achieve the intended effect in practical operation. Therefore, for this current situation, there is an urgent need in the industry for a device capable of polishing two sides of a plate separately, so as to more flexibly meet the personalized needs of different customers, and reduce the technical threshold of the equipment, and improve the polishing quality and efficiency, thereby effectively solving the above problems.
