The principle of protective film coater (above).

The two ends of the protective film coating mechanism are installed on the vertical support arm of the coating machine, and through the transmission of belt, chain or cable, the protective film coating mechanism moves high and low and is coated along the surface of the wire mesh. The head structure is continuously applied to the servo or variable frequency motor, so that it can be used safely and can accurately control the position of the protective film coating mechanism. Before coating, the protective film coater loads the clean, taut mesh plate from the front of the coater.
