A novel magnetic layered reclaimer mechanism for square tin cover glue-injection and drying machine was introduced. The 3D model of magnetic layered reclaimer mechanism was created via 3D modeling software CREO. The structure of magnetic layered and the crank-slider reclaimer mechanism were analyzed. The movement characteristic curve of the slider block was simulated via MATLAB program. The magnetic layered reclaimer mechanism can make square tin covers in sequence with same distance and parallel placement. The movement characteristic curve of the slider block was a kind of sine curve, indicating that the sliding block was a kind of flexible movement, and it made the reclaimer movement more smoothly. The magnetic layered reclaimer mechanism can make square tin cover glue-injection and drying machine running reliably and getting good processing quality.
