At the same time, the first gear drives the cleaning roller set between the two groups of grinding rollers to rotate, so that the brush on the spring surface of the cleaning roller starts to grind The roller is cleaned to prevent wood chips generated by grinding the grinding roller from adhering to the grinding roller. When the spring rotates to the bottom of the cleaning roller, the extrusion block arranged under the cleaning roller by the lifting block begins to squeeze the protrusion through the arc surface of the protrusion, so that the extrusion block drives the telescopic plate to squeeze the spring, and the telescopic plate drives the brush to retract into the telescopic groove. When the cleaning roller continues to rotate, the spring rebounds the telescopic plate. At this time, the back and forth expansion and contraction of the spring causes the brush to shake, and the wood chips attached to the brush are shaken off and fall onto the surface of the conveyor sand belt. The conveyor sand belt drives the wood chips to fall naturally from the edge of the grinding table through transmission, and fall into the collection frame for unified collection, which is convenient for cleaning. A brush plate is arranged on the bottom of one side of the conveyor sand belt of the grinding table, and the brush plate is also arranged in the collection frame. When the conveyor sand belt rotates, the bristles on the collection frame can continue to clean the conveyor sand belt to prevent wood chips from adhering to the surface of the conveyor sand belt.
