[0002] The vacuum aluminum coating machine is a device that heats and melts aluminum metal, and the evaporated aluminum vapor condenses on the film surface to form an aluminum coating layer. It is mainly composed of an unwinding device, a winding device, and a vacuum evaporation chamber. It passes through the unwinding device and The winding device passes the material through the vacuum evaporation chamber and completes the aluminum plating operation. However, in the actual process, due to the static electricity generated by friction during the unwinding and winding process, the discharge of static electricity along the molten aluminum vapor will cause static lines, which will cause Affect the effect of aluminum plating. The traditional technology mainly uses a grounding wire to remove static electricity. However, since the surface of the drive roller shaft has a plastic layer, it is mainly used for protective materials. However, the conductive effect of the plastic layer is relatively limited, so a single grounding is used. The wire removes static electricity, and its effect of removing static electricity is relatively limited, so the applicability and practicability are limited
