Winding device of vacuum coating machine

The utility model relates to a winding device of a vacuum coating machine in the technical field of vacuum coating. The cutting device comprises a support, a pressing assembly, a cutting assembly, a winding assembly and a guide cylinder. According to the film coating device, a film subjected to film coating is pressed through the pressing assembly, so that the film is smoother, the pressing effectis good, the moving block can move along the guide rod, and the second pressing roller can automatically adjust the position of the thickness of the film under the action of the spring and is alwayspressed on the film and the first pressing roller; a thin film bypasses the guide cylinder and is connected with the winding cylinder, when the thin film passes through the guide cylinder, slitting isconducted through the cutting knife, the machining efficiency is improved, the cutting knife can move along cutting according to actual needs, then tightening and positioning are conducted through the fastening screw, and ther
