A special negative pressure vacuum chamber structure for online grinding of cathode rollers

Abstract

The invention discloses a special negative-pressure dust collection cavity structure for online grinding of a cathode roller, and belongs to the technical field of cathode roller grinding equipment. According to the technical scheme, the special negative-pressure dust collection cavity structure comprises a bottom plate, and parallel side plates are arranged at the two ends of the bottom plate inthe vertical direction correspondingly; the end faces, opposite to the cathode roller, of the side plates are first arc-shaped faces matched with the cathode roller, and an arc-shaped plate is arranged between the two first arc-shaped faces; a first receding hole is formed in the middle of the arc-shaped plate, and a grinding wheel located at the working position extends out of the first recedinghole and grinds the cathode roller; and a sealing end plate is arranged between the lower portion of the other end face, opposite to the first arc-shaped face, of each side plate and the bottom plate,a sealing top plate is arranged at the upper ends of the two side plates, and second receding holes allowing a rotating frame and the grinding wheel to pass through are formed among the sealing end plate, the side plates and the sealing top plate. The invention aims to provide the special negative-pressure dust collection cavity structure for online grinding of the cathode roller, which is ingenious in structure, convenient to use and good in effect, and used for online grinding equipment for the cathode roller.

Description

Technical field [0001] The invention relates to a special component for a grinding device for a cathode roller, and more particularly, to a negative pressure dust suction chamber structure special for on-line grinding of a cathode roller. Background technique [0002] The cathode roller is the main equipment for the production of electrolytic copper foil. After long-term use, the surface conductivity of the cathode roller will decrease, the roller surface will generate heat locally, and the shaft end will generate heat, which will cause quality problems such as mottling on the produced electrolytic copper foil. At present, in view of the decline in the surface conductivity of the cathode roller, if it is not serious, it is repaired by manual prior polishing. If it is serious, it is necessary to stop the machine and hoist the cathode roller to a special cathode roller grinding equipment for depth. Repair it, or send it to a third-party professional repair organization for repair....

AI Technical Summary

Problems solved by technology

This method of shutdown and hoisting not only has low work efficiency and seriously affects production, but also because the cathode roller is heavy, once bumped or dropped during the hoisting process, the cathode roller may be directly scrapped

With online grinding, the first thing to solve is the dust removal problem. If there is no reasonable and ingenious structure, the dust debris generated by grinding will fall into the anode groove and affect the production of copper foil.
