Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figures 1-3, the utility model provides a technical solution: a retracting device for PVDF fluorine film production, including a base 6, the upper end of the base 6 is provided with a first fixing frame 2, and the upper end of the base 6 is also provided with a second Two fixed mounts 9, the base 6 is provided with a mounting frame, and the base 6 mounting frame is provided with a roller 7, and the outer set of the roller 7 is provided with two groups of conductive rings 14, the base 6 mounting frame of this structure plays the role of fixing the roller 7 Function, so that the roller 7 can contact the winding film, and the conductive ring 14 on the roller 7 can also contact the winding film. The conductive ring 14 is symmetrically distributed about the center line of the roller 7, and the outer portion of the conductive ring 14 is attached with an arc conductive plate 8, and the conductive plate 8 is installed on the base 6, the arc-shaped conductive plate 8 of this structure will not affect the rotation of the conductive ring 14, and at the same time, it can conduct static electricity away from the conductive ring 14 to prevent the winding film from leaving Excessive static electricity, rectangular through holes are provided on both sides of the first fixed frame 2, and the first shaft roller 3 and the second shaft roller 13 are arranged in the first fixed frame 2, and the through holes of the first fixed frame 2 are provided with Spring 12, the upper end of the first fixed mount 2 is provided with a threaded hole, and the first fixed mount 2 perforation is provided with a threaded rod 1, the threaded hole on the first fixed mount 2 of this structure plays the role of fixing the threaded rod 1, through The threaded rod 1 can pressurize the first shaft roller 3, and the first shaft roller 3 will compress the spring 12 to control the tension between the first shaft roller 3 and the second shaft roller 13.
