Abstract: In view of the technical development status of zinc smelting industry at home and abroad, taking the new generation of large electrode plate automatic zinc stripping unit developed by Beikuang Electromechanical Technology Co., Ltd. as the research object, this paper first introduces the basic structure and working process of large electrode plate automatic zinc stripping unit, and then carries out structural design and working process analysis on the automatic loading and unloading mechanism of cathode plate, which solves the disadvantage that the imported zinc stripping machine needs manual auxiliary hook plate, The automatic loading and unloading of cathode plate is realized, and the complete unmanned operation is realized, which greatly improves the zinc stripping efficiency and the safety and reliability of the equipment, which has important guiding significance for engineering application.
