[0029] When grinding the outer circumference of the roller, the roller to be processed is mounted on the connecting plate 23 on the outer circumference of the rotating ring 21, and the roller is clamped and fixed by the clamping mechanism 3 provided on the connecting plate 23, so that the mounted roller can be ground in turn.

[0030] like Figure 2 and Figure 3As shown, the clamping mechanism 3 includes a second motor 31 and a cylindrical shell 32. The second motor 31 is installed on the outer wall of the connecting plate 23 close to the support seat 2. The output end of the second motor 31 is coaxially fixed with a second rotating shaft 311 which passes through the connecting plate 23 coaxially with the rotating ring 21. The cylindrical shell 32 is coaxially fixed to the end of the second rotating shaft 311 away from the second motor 31. Four cylinders 33 are installed on the inner wall of the cylindrical shell 32.

Under the meshing cooperation of the spur gear 13 and the ring gear 22, the first rotating shaft 12 drives the rotating ring 21 to rotate, prompting the roller at the next workstation to move to the designated position for grinding in turn. When the grinding mechanism 4 is grinding the roller at the designated position, the staff can load or unload the roller at other workstations, thereby reducing the downtime and waiting time during the roller grinding process and improving the grinding processing efficiency.

The first rotating shaft 12 can drive the second reciprocating screw rod 6 to rotate, causing the cleaning brush 61 to slide through the tops of multiple through holes.

[0037] During the rotation of the first rotating shaft 12, the meshing cooperation of the first bevel gear 631 and the second bevel gear 632 drives the second reciprocating screw 6 to rotate, prompting the cleaning brush 61 to reciprocate on the top surface of the base 1 and clean the grinding waste chips that fall on the top surface of the base 1, so that the waste chips accumulated on the top surface of the base 1 are swept into the through opening 15 and enter the receiving box 14 for collection, thereby reducing the possibility of the waste chips that fall on the top surface of the base 1 flying around at will, and reducing the trouble of manually cleaning the surface of the base 1.
