Description

Technical Field

[0002] Bamboo boards are made of processed and exquisite bamboo pieces that are glued and pressed together. Bamboo board production usually requires 4-6 year old large-diameter nanmu bamboo, which is processed through dozens of processes such as sawing, slicing, rough planing, high-temperature steaming, high-pressure carbonization, drying, fine planing, color selection, embryo pressing, sanding, etc. It has excellent physical properties and has the advantages of small water absorption and expansion coefficient, no cracking, and no deformation.

[0003] The board used in the production of bamboo boards is made of multiple bamboo strips. Therefore, the bamboo boards need to be finely polished during the processing to ensure that their surfaces are smooth and flat. However, when the existing equipment polishes the rough bamboo boards, a motor is used to drive the drum and sandpaper to rotate at high speed. While the sandpaper rotates, it rubs against the surface of the rough bamboo board to polish the rough bamboo board. However, due to the high-speed rotation of the motor, the sandpaper on the drum is easily offset, causing the sandpaper to be thrown off the drum, resulting in the inability to polish the rough bamboo board, thereby reducing the factory productivity; and the existing equipment can only achieve single-sided polishing of the rough bamboo board, so the rough bamboo board needs to be put into the equipment for a second time, which is cumbersome to operate.
