[0002] Density fiberboard, also known as density board, is made of pure wood fiber or other plant fiber as raw materials, which is prepared by fiber preparation, applied with synthetic resin, and pressed under heating and pressure conditions. Density board is widely used in furniture, decoration, musical instruments and packaging fields due to its uniform structure, fine material, stable performance, impact resistance and easy processing. The main advantages of density board include easy coating and processing. Various coatings and paints can be evenly applied on the density board. It is the preferred substrate for paint effects. At the same time, density board is also a beautiful decorative board. Various veneers, printed papers, PVC, adhesive tape films, light metal sheets and other materials can be finished on the surface of the density board.

[0003] In the production process of density fiberboard, there may be some uneven or pre-cured parts on the surface of the board after hot pressing. These parts not only affect the aesthetics of the board, but also affect the performance of the board. Therefore, a sanding machine is needed to process and correct the surface of the board to remove the uneven and pre-cured parts on the surface of the board, so as to make the surface of the board smoother and flatter.

[0004] In the process of using a sanding machine to process the board, due to the insufficient flatness of the board surface and the uneven thickness of the board surface, the running trajectory of the board may become unstable when passing through the inside of the sanding machine, and may shake or deviate, resulting in uneven sanding effect and poor quality of the finished product.

[0028] A protective pad 8 is provided on the side of the limit plate 5 away from the mounting groove 7, and the elastic member is a spring 9. One end of the spring 9 is fixedly connected to the inner side of the mounting groove 7, and the other end of the spring 9 is fixedly connected to the side of the limit plate 5 away from the protective pad 8. The driving assembly includes a power member and two mounting columns 10. A slide groove 11 for the connection plate 3 to move is provided on the surface of the sanding equipment 1, and one end of the two mounting columns 10 is respectively rotatably connected to the two sides of the inside of the slide groove 11, and the other ends of the two mounting columns 10 are fixedly provided with a bevel gear 12.
