The height of the film scraping roller 3 is changed according to production needs, thereby changing the thickness of the film during coating. When adjustment is needed, it can be manually operated according to the external control device. When the external control device sends a command to the frequency conversion motor 13, the output shaft of the frequency conversion motor 13 drives the first pulley 16 to rotate, and the belt 17 covered on the outside of the first pulley 16 rotates at the same time, and the distance between the first pulley 16 and the second pulley 18 on the inner side of the belt 17 is slightly longer than the belt 17, so The second pulley 18 and the belt 17 are tensioned, and through the connection of the belt 17, when the first pulley 16 rotates, the second pulley 18 rotates at the same time, and the second pulley 18 drives Logan to rotate between the mounting ring and the tensioning ring 10.
