[0007] The above technical scheme is adopted, the washers to be processed are poured into the roller, the washers are located between the two partitions, the roller is rotated to polish the washers, when the roller polishing machine stops rotating, the washers fall to the bottom of the roller, the lead screw is rotated, the sliding block of the lead screw drives the lifting mechanism and the electric grinding wheel to move to between the two partitions through the opening of the backboard by the connecting plate one, the lifting mechanism drives the electric grinding wheel to descend, the wool wheel is in contact with the washers, the motor drives the wool wheel to rotate, the washers are polished again, and the washers do not need to be taken out of the roller.

[0008] As a preferred option, the connecting plate one is fixedly connected to a baffle plate at one end close to the partition.

[0009] Adopting the technical scheme, when the electric grinding wheel is located between the partition plate and the end of the roller, the baffle blocks the opening of the partition plate, preventing the roller polishing machine from polishing the gasket, and the gasket falls between the partition plate and the end of the roller.

[0010] Preferably, the lifting mechanism is a pneumatic cylinder, which is fixedly connected with the connecting plate one and the connecting plate two.

[0011] Adopting the technical scheme, the electric grinding wheel is lifted and lowered by the pneumatic cylinder.

[0012] Preferably, an opening is formed in a side wall below the roller, and a cover plate is hinged to the opening.

[0013] Adopting the technical scheme, the cover plate is opened, and the wool wheel of the electric grinding wheel inside the roller is replaced.

[0014] Preferably, the connecting plate two is fixedly connected with a protective cover, and the motor is located inside the protective cover.

[0015] Adopting the technical scheme, the motor is prevented from being damaged by the outside. BRIEF DESCRIPTION OF DRAWINGS
