Structure of material removing mechanism was improved for the defects of original aluminum foil separator. In this structure transformation, the original cylinder drive is replaced by cam mechanism, forming a new type of material removing mechanism. In the Pro/e environment, surrounding and columniform cam of material removing mechanism conducted parametric design. In Mechanism module, through the motion simulation and measurement verification of material removing mechanism, the relative position of the two cams can be adjusted, ultimately reducing the design cycle and providing a reference for the structure optimization in the later period.
