when the electrolyte scraping device 20 works, the translation driving part 21 drives the square moving plate 22 to move so as to move the two liquid scraping plates 23 to the boss covering the edge of the cathode roller 10, along with the movement of the liquid scraping plates 23, the roller edge liquid scraping cover plate 24 compresses the compression spring 25, the side edge of the roller edge liquid scraping cover plate 24 is tightly attached to the side edge of the cathode roller 10, along with the rotation of the cathode roller 10, the electrolyte is scraped, and the scraped electrolyte automatically falls into the electrolytic cell 11;

when the translation driving component 21 works, the execution end of the driving motor 212 drives the screw rod 213 to rotate, and the screw rod 213 drives the square moving plate 22 to move horizontally through the transmission hole 214;

when the drying device 40 is operated, the pneumatic cylinder 41 drives the heating box 42 to move until the heating box 42 covers the side edge of the cathode roller 10, at this time, the heater 44 performs heating treatment to facilitate moisture evaporation, and the air source pipe 43 performs air transmission to facilitate air flow;

before the air flow grinding device 50 and the wet grinding device 60 work, the driving cylinder 14 drives the grinding positioning box 13 to move, so that the cathode roller edge clamping interface 131 is clamped with a boss at the edge of the cathode roller 10, the cathode roller edge clamping interface 131 is covered with rubber, and the sealing effect is achieved while the rotation of the cathode roller 10 is not influenced;

when the air flow grinding device 50 works, the execution end of the electric cylinder 511 drives the air mill positioning block 512 to move until the air flow passage 513 covers the side edge of the cathode roller 10, so that the positioning can be completed, at the moment, the air pump 521 transmits high-pressure air into the air flow passage 513 through a pipeline, oxides which are easy to fall off are stripped by the high-speed air flow, the high-speed air flow carrying the oxides enters the recovery box 522 through the pipeline, the air flow is filtered by the filter screen 523 and then discharged, and the oxides are collected in the recovery box 522;

when the wet grinding device 60 works, the execution end of the transmission motor 611 drives the funnel-shaped grinding disc 612 to rotate, and the funnel-shaped grinding disc 612 grinds the side edge of the cathode roller 10;

when the circulating leaching part 62 works, the first water pump 622 sucks the grinding fluid in the water tank 621, and the grinding fluid is discharged into the grinding positioning box 13 through a pipeline to be subjected to auxiliary grinding, the grinding fluid naturally leaks in the grinding positioning box 13 due to the action of gravity, the grinding fluid enters the water return box 624 after being filtered by the filter plate 625, and the grinding fluid in the water return box 624 is sucked and discharged into the water tank 621 by the second water pump 623 to complete circulation;

when the cleaning member 63 is cleaned, the actuating end of the air cylinder 631 drives the cleaning box 632 to move, and the oxides on the filter plate 625 are absorbed by the cleaning box 632 and the negative pressure suction pipe 633.

The invention is described above with reference to the accompanying drawings, it is obvious that the invention is not limited to the above-described embodiments, and it is within the scope of the invention to adopt such insubstantial modifications of the inventive method concept and solution, or to apply the inventive concept and solution directly to other applications without modification.
