The invention discloses a zinc plate stripping system with functions of removing plates, supplementing plates, and transferring cathode plates. The zinc plate stripping system comprises A column of electrolytic baths and B column of electrolytic baths. The A column of electrolytic baths and the B column of electrolytic baths respectively correspond to A zinc stripping lines and B zinc stripping lines; a manual zinc stripping and plate brushing line is also arranged; the A zinc stripping lines and the B zinc stripping lines have the same structures and comprise pre-stripping equipment, main stripping equipment, plate brushing equipment, plate removing equipment, plate supplementing equipment, cathode plate transferring equipment, cathode plate spacing adjusting equipment and cathode plate transverse-moving equipment. The problems that an existing mechanical zinc stripping unit cannot be favorably matched with a cathode plate crane, and the cathode plate crane cannot hoist removed bad plates and qualified cathode plates are solved, meanwhile, the operation efficiency of plate removing and plate supplementing is improved, the mechanical transferring of the cathode plates from the zinc stripping lines to the plate brushing line is realized, the work load of the cathode plate crane is reduced, the production efficiency of zinc stripping is improved, and the labor intensity of working personnel is reduced.
