When the polishing of one side of the support assembly 6 is completed and flipping is required, the polishing mechanism is transferred to the other support assembly 6 to polish the decorative board. For the decorative board that needs to be flipped, first, each first lifting cylinder 65 drives the positioning frame 67 to lift, and then the positioning frame 67 and the decorative board in the positioning frame 67 are driven to rotate by the drive of each rotating motor 66. After the rotation is completed, it is lowered by the first lifting cylinder 65 to press against the support base 64. After the polishing of the other side of the decorative board is completed, the polishing mechanism is transferred to the upper part of the decorative board after flipping, and then the other side of the decorative board is polished. The other side of the decorative board is flipped again. After the polishing is completed, the polishing assembly 7 is transferred to the other side for polishing. The operator can remove the decorative board that has been polished on both sides and replace it with the decorative board that needs to be polished, and polish each decorative board in this way, effectively solving the problems of low efficiency and poor quality caused by manual polishing in the prior art. By automatically loading, positioning, flipping, and polishing the decorative board, while greatly improving the polishing quality and efficiency of the decorative board, it can also suck the dust and debris generated during the polishing process in time, ensuring the cleanliness of the polishing environment and the personal safety of the operator at the same time. The structure is ingenious, convenient and practical.
