[0055] like Figures 1-10 As shown, the polishing method of the polishing device specifically includes the following steps:

[0056] S1. The roller 7 is sent to the clamping module 2 for clamping through the polishing module 3; the limit block on the flap 36 supports the roller 7, which facilitates the clamping of the clamping assembly 24. The offset of the roller 7 during placement can control the lifting hydraulic cylinder 21 to adjust the position of the clamping assembly 24 to prevent excessive polishing during offset clamping;

[0057] S2, the grinding module 4 grinds the roller 7 to remove the oxide layer and wear; the limit block on the flap 36 controls the roller 7 to turn downward at a certain angle after clamping, and then controls the grinding wheel 454 to start grinding;

[0058] S3: The debris guide module 5 adjusts the direction of the debris that rebounds and flies toward the drum 7. The flaky debris generated during grinding can easily scratch the surface of the drum 7. The debris guide module 5 sprays airflow in different directions to impact the surface of the flaky debris, adjusts the surface direction of the flaky debris, and reduces the damage caused by the surface collision when the flaky debris hits the drum 7.

[0059] S4, the impact nozzle 6 can intermittently eject a jet to impact and drop the abrasive particles that cannot fall off the grinding wheel 454 after being worn; the impact nozzle 6 intermittently introduces water flow and high-pressure air, the high-pressure air increases the water flow speed, and the high-speed water flow impacts and drops the abrasive particles that cannot fall off the grinding wheel 454 after being worn;

[0060] S5, the polishing module 3 polishes the polished roller 7; after the polishing is completed, the flap 36 is rotated at a certain angle to control the polishing roller 38 to polish the roller 7, and the slag box 391 collects the debris generated by polishing, and the gas is ionized by the ionization needle 399. The dust removal nozzle 396 sprays gas with positive and negative charges to clean the debris on the polishing roller 38 to prevent the debris from being adsorbed on the polishing roller 38 due to static electricity.

[0061] The working principle of the present invention is as follows: the limit block on the flap 36 supports the roller 7, the clamping assembly 24 clamps the roller 7, and the offset when the roller 7 is placed can control the lifting hydraulic cylinder 21 to adjust the position of the clamping assembly 24. The limit block on the flap 36 controls the roller 7 to flip downward at a certain angle after clamping, and then controls the grinding wheel 454 to start grinding. The debris guide module 5 sprays air in different directions to impact the surface of the flaky debris, adjusts the surface orientation of the flaky debris, and intermittently introduces water flow and high-pressure air into the impact nozzle 6. The high-pressure air increases the water flow speed, and the high-speed water flow impacts the abrasive particles on the grinding wheel 454 that cannot fall off after wear. After grinding is completed, the flap 36 is rotated at a certain angle to control the polishing roller 38 to polish the roller 7. The slag box 391 collects the debris generated by polishing, and the gas is ionized by the ionization needle 399. The dust removal nozzle 396 sprays gas with positive and negative charges to clean the debris on the polishing roller 38.
