[0069] It should be noted that when the fan is started, the baffle 822 tilts inward under the suction force and fits against the inner wall of the lower end of the air collecting port, and debris enters the dust collecting hood 820 normally. When the fan is turned off, the baffle 822 is reset under the elastic force of the spring 823, blocking the air collecting port to prevent larger particles of debris on the filter 821 from falling out of the dust collecting hood 820.

The workpiece to be polished is placed in the positioning block (220), and the cylinder (110) is started to drive the push rod (120) and the clamping block (130) to move, thereby clamping and fixing the workpiece; S2. The second motor (450) is started to drive the first screw (460) to rotate, the positions of the second bottom plate (430) and the workpiece are adjusted, and the first bottom plate (410) is moved close to the grinding mechanism (300) by moving the pushing rod (620) to push the workpiece until the side of the workpiece to be ground is in close contact with the sanding belt (340); S3. Start the first motor (310) to drive the first roller (320), the second roller (330) and the sanding belt (340) to rotate, support the sanding belt (340) from the inside through the support plate (350) to ensure that the sanding belt (340) is in good contact with the workpiece, gradually advance the sanding belt (340) during the sanding process through the advancing mechanism (600) to control the degree of sanding, and control the equipment switch through the operating mechanism (500) to adjust the sanding speed; S4.
