[0034] In the utility model, the working steps of the device are as follows:

[0035] The first step: by starting the pulley motor 9, the transmission belt 10 and the transmission wheel 11 can drive the rotating shaft 4 and the sanding belt 5 to rotate, and the surface of the workpiece is polished. When the waste dust generated by the workpiece during the polishing process is adsorbed on the surface of the sanding belt 5, the negative pressure pump 603 is started to operate, and pneumatic conveying is performed through the collection box 602 and the guide pipe 604, so that the dust hood 605 generates suction, and the waste dust on the surface of the sanding belt 5 is sucked into the interior of the collection box 602, and then the waste dust is filtered and intercepted by the filter screen plate 606, so that it remains in the collection box 602 for collection, and the bending angle of the sanding belt 5 can be reduced by the guide roller 601, so that the attachments of the sanding belt 5 passing the outside of the guide roller 601 are dispersed and easier to fall off, and the waste that is not sucked into the dust hood 605 continues to move to the brush plate 607, and the waste dust is cleaned by the brush plate 607 to achieve the effect of secondary cleaning.

[0036] The second step: when the filter screen plate 606 has been working for a long time and the filter holes are clogged and need to be cleaned or replaced, the handle 705 can be pushed to drive the connecting block 703 and the clamping block 704 to move, so that the clamping block 704 is retracted into the interior of the fixed block 701 and disengaged from the clamping groove 8 to disconnect the clamping relationship. Then the filter screen plate 606 can be pulled out to be cleaned or replaced. During the replacement process, the connecting block 703 and the clamping block 704 are driven to move by the restoring force of the spring 702, so that the clamping block 704 is inserted into the clamping groove 8 to complete the clamping fixation.
