The nut on the top is used to adjust the position of the rotating shaft. The rotating shaft rotates in the direction of the screw. The limiting rod slides along the waist groove on the support seat accordingly until the surface of the abrasive belt is embedded in the screw groove between the screw edges and pressed, and then the limiting rod is locked to limit the rotation of the rotating shaft through the limiting sleeve. After the positioning is completed, the rotating top drives the screw to rotate, and the motor drives the driving wheel to rotate, and the tensioning wheel and the driven wheel follow. The abrasive belt moves synchronously with the pulley assembly. The moving direction of the abrasive belt is opposite to the rotation direction of the screw. The screw slider mechanism drives the positioning seat to move horizontally as a whole, and the abrasive belt is polished evenly along the direction of the screw groove.
