In some embodiments of the present invention, as shown in fig. 1, the position adjustment mechanism 300 includes a cylinder 310 and a connecting plate 320.

The air cylinder 310 is mounted to the fixed frame 200. The connection plate 320 is mounted to the cylinder 310, the dust removal suction cap 400 is mounted to the connection plate 320, and the cylinder 310 drives the connection plate 320 and the dust removal suction cap 400 to move between the first position and the second position. The air cylinder 310 may be a rodless air cylinder, and the air cylinder 310 is provided with a magnetic switch, and when the dust removal suction hood 400 is determined to be in the first position, the first grinding wheel 110 is started to perform the grinding operation, and when the dust removal suction hood 400 is determined to be in the second position, the second grinding wheel 120 is started to perform the grinding operation.

The dust removing suction cap 400 is mounted to the connection plate 320 so that the connection plate 320 and the dust removing suction cap 400 can be moved together by the cylinder 310. The connection plate 320 extends toward the grinding unit 100, so that the distance from the dust-removing suction cap 400 to the first grinding wheel 110 and the second grinding wheel 120 is shortened, dust-collecting efficiency is improved, and interference between the dust-removing suction cap 400 and the cylinder 310 due to too close distance is prevented.

In some embodiments of the present invention, as shown in fig. 2, the connection plate 320 is configured with a vertically extending slot 322, and the connection plate 320 is mounted to the slide rail by fasteners passing through the slot 322. The mounting position of the fastener in the slot 322 can be adjusted, and the mounting position of the connecting plate 320 relative to the cylinder 310 can be adjusted by fastening the fastener at different positions of the slot 322, so that the effect of adjusting the position of the dust removal suction hood 400 is achieved, and the position of the dust removal suction hood 400 can be adjusted to adapt to the positions of the first grinding wheel 110 and the second grinding wheel 120, so that dust generated during the operation of the first grinding wheel 110 and the second grinding wheel 120 can be absorbed more accurately.

In some embodiments of the present invention, as shown in fig. 2 and 3, the dust removal suction hood 400 includes a diffusion portion 410 and a dust prevention portion 420. The diffuser 410 is mounted to the connection plate 320, and the cross-sectional area of the diffuser 410 is gradually increased toward the sanding unit 100. The dust prevention part 420 is connected to a side of the diffusion part 410 facing the sanding unit 100 and extends toward the sanding unit 100, and a cross-sectional area of the dust prevention part 420 is maintained constant.

The dust removal suction hood 400 can form a negative pressure, and the diffusion portion 410 gradually increases the cross-sectional area towards the direction of the polishing unit 100, so that the dust removal suction hood 400 can collect dust at the first grinding wheel 110 and the second grinding wheel 120 in a large range, and the dust is concentrated to the smaller cross-sectional area of the diffusion portion 410, thereby facilitating further absorption of the dust. The dust-proof part 420 can shield dust scattered to the outside of the dust-removal suction cover 400 on the side of the diffusion part 410 facing the polishing unit 100, prevent the dust from being scattered to the region other than the dust-removal suction cover 400, and maintain high cleanliness of the polishing environment.
