The rotating assembly 83 includes a rotating portion 831 and a telescopic portion 832. The rotating portion 831 and the telescopic portion 832 are respectively connected to the positioning assembly 82. The positioning assembly 82 controls the cleaning brush 81 to move in the vertical direction by cooperating with the telescopic portion 832. When grinding, the cleaning brush 81 is located above the grinding disk 71. When cleaning, the cleaning brush 81 is located below the grinding disk 71. When the cleaning brush 81 is located below the grinding disk 71, the positioning assembly 82 controls the cleaning brush 81 to rotate below the grinding disk 71 by cooperating with the rotating portion 831.

At this time, the second transmission gear plate 8312 and the first transmission gear plate 8311 are engaged with each other, and the second motor 54 drives the transmission column 7 to rotate and then drives the first transmission gear plate 8311 to rotate. The first transmission gear plate 8311 and the second transmission gear plate 8312 are engaged for transmission, which can drive the vertical cylinder 822 and the rotating column 821 to rotate around their own axes.

[0032] Initially, the extrusion spring 8323 applies a thrust to the sliding block 8322. At this time, the sliding block 8322 is at the top of the telescopic slot 8321. When the supporting plate 4 moves upward and the grinding disc 71 needs to be cleaned, the bottom end of the extrusion rod 8325 passes through the through hole 8324 and moves to the bottom of the supporting plate 4. The roller 8326 at the bottom end of the extrusion rod 8325 contacts the second transmission gear disc 8312. The supporting plate 4 continues to move upward. The extrusion rod 8325 and the roller 8326 cooperate with each other to apply a vertical downward thrust to the second transmission gear disc 8312. The second transmission gear disc 8312 moves downward along the surface of the rotating column 821.

[0034] When it is necessary to clean the powder debris filled on the surface of the grinding disc 71 during the grinding process, the bearing plate 4 moves vertically upward, the bottom end of the extrusion rod 8325 passes through the through hole 8324 and moves to the bottom of the bearing plate 4, the roller 8326 at the bottom end of the extrusion rod 8325 contacts the second transmission toothed disc 8312, the bearing plate 4 continues to move upward, the extrusion rod 8325 and the roller 8326 cooperate with each other to apply a vertical downward thrust to the second transmission toothed disc 8312, and the second transmission toothed disc 8312 moves downward along the surface of the rotating column 821.
