Abstract: Aiming at the problem that it was difficult to realize the synchronous opening and closing of pallets by the existing stacking mechanism of zinc sheets, which caused the irregular stacking of zinc sheets and affected the production efficiency, a new synchronous stacking opening and closing device was designed by using the linkage slider mechanism. Through the establishment of the mathematical model of the opening and closing mechanism of synchronous palletizing, the kinematics analysis was carried out by using MATLAB, and the key connecting rod dimensions were calculated and optimized. Based on Creo, a threedimensional model of stacker opening and closing mechanism was established, the structure of the device was refined, and the kinematic simulation was carried out. The rationality of the mechanism was verified by the simulation results. By comparing the simulation results of different connecting rod sizes, the optimal scheme of key connecting rod sizes was verified. The research results indicate that the structure of the new design stacker opening and closing mechanism is reasonable and meets the action requirements. After the size optimization, the movement performance is further optimized. The structure can also provide reference for the design of similar equipment in the future.
