[0015] There are multiple transmission rollers, and the transmission rollers are arranged inside the table. A transmission shaft is fixedly installed on the side wall of the transmission roller. The transmission shaft is rotatably installed inside the table, and one end of the transmission shaft close to the transmission box extends to the inside of the transmission box;

[0016] A transmission belt is sleeved on the side walls of multiple transmission shafts, and the output shaft of the transmission motor is fixedly connected to the adjacent transmission shafts.

[0028] Compared with the prior art, the present invention has the following significant advantages:

[0029] First, the present invention passes the polishing belt through two through grooves, places the tool to be polished on the top of the table, and then wraps the workpiece with the polishing belt. At this time, the output end of the polishing motor drives the driving shaft to rotate, so that the polishing belt rotates, and the polishing belt polishes the side wall of the workpiece. By wrapping the workpiece with the polishing belt, it is convenient to polish the side wall of the workpiece; it solves the existing problem of needing to frequently adjust the position of the workpiece.

[0030] Secondly, the present invention controls the downward movement of the mounting frame by rotating the extrusion screw, so that the extrusion roller can press on the side wall of the workpiece, ensuring the stable position of the workpiece and avoiding the synchronous rotation of the workpiece with the rotation of the polishing belt.

[0031] Third: The present invention drives the transmission shaft to rotate through the output shaft of the transmission motor, and drives multiple transmission shafts to rotate synchronously through the transmission of the transmission belt. The workpiece is placed on the top wall of the table so that the workpiece contacts the side wall of the transmission roller. Therefore, when the transmission shaft rotates, it drives the workpiece to move, so that the polishing belt gradually polishes various positions of the side wall of the workpiece.

[0032] Fourthly, the present invention limits the position of the driving shaft by the mutual cooperation of the positioning groove and the positioning ring, thereby preventing the driving shaft from tilting inside the positioning frame under the pull of the polishing belt. By fitting the pressing plate with the side wall of the driving shaft and then fixing the position of the pressing plate through the extension rod and the fixing frame, the pressing plate can position the position of the driving shaft, thereby further ensuring the stability of the position of the driving shaft.

[0033] Fifth: The present invention covers the top of the desktop with a protective cover, so that the dust generated during processing can be gathered inside the protective cover, preventing the dust from spreading around. The air inside the air intake frame and the air intake pipe is sucked away by an external fan, so that the interior of the air intake frame and the air intake pipe is in a negative pressure state. The dust inside the protective cover is therefore sucked into the interior of the air intake pipe and discharged to the outside, preventing the dust generated during processing from spreading everywhere.
