At this time, the first rack drives the gear to rotate through meshing, and the gear moves to one side through meshing while rotating. At this time, the second rack pushes the clamping plate to move to one side when moving, and the clamping plate acts on the side of the stone when moving. Since the stone is heavy, Therefore, the depth of the pad moving down will be greater. At this time, the splint and the protective pad will be firmly fastened to both sides of the stone, thereby improving the stability of the stone and preventing the stone from being unstable due to the roughness of the bottom of the stone, thereby causing deviation in the grinding of the stone.

The present invention provides a grinding mechanism and a cleaning mechanism. When the stone is fixed, the grinding mechanism is started and the stone is ground. During this period, the turntable rotates synchronously with the rotation of the grinding roller. The push rod drives one end of the swing plate to swing back and forth up and down under the action of the pin shaft and the shaft sleeve, while the other end of the swing plate deflects in the opposite direction. When the swing plate deflects, the other end drives the cleaning plate to swing back and forth up and down, so that the reciprocating swing of the cleaning plate can facilitate the cleaning of the debris adhering to the surface of the grinding roller during grinding. Thereby improving the grinding effect of the grinding mechanism on the stone and preventing impurities from adhering to the surface of the grinding roller and affecting the grinding of the stone. When the cleaning plate is reset under the elastic force of the first spring, the top of the cleaning plate will squeeze the buffer pad. At this time, the gas inside the buffer pad will be transported to the inside of the conduit through the connecting pipe after being squeezed, and the gas will be blown obliquely to the grinding part of the stone through the nozzle, so as to facilitate the treatment of the powder generated during grinding through the airflow, prevent dust from interfering with the grinding of the stone, and thus cause deviation in the grinding of the stone.
