Technical Field

[0001] The utility model relates to the technical field of static eliminators, in particular to a static eliminator for the surface of an optical film. Background Art

[0002] An optical film is an optical dielectric material composed of thin layered dielectrics that propagates light beams through interfaces. It is widely used in the fields of optics and optoelectronics. During the manufacturing process of an optical film, charged ions are easily adhered to the surface of the optical film, and these charged ions can easily affect the winding and cutting of the optical film. Therefore, it is necessary to perform static elimination on the film when manufacturing an optical film.

[0003] Currently, static elimination operations are all carried out using static eliminators to eliminate static electricity from optical films. For example, an optical film surface static eliminator disclosed in Chinese Patent Publication No. "CN213230731 U" includes a base, a lower static elimination roller, and an upper static elimination roller. A lower static elimination roller is provided on the upper right side of the base, and an upper static elimination roller is provided corresponding to the optical film above the lower static elimination roller. A first spring is provided corresponding to the upper static elimination roller above the lower static elimination roller.

[0004] Currently, optical films are all wound around a hollow center roller, and the diameter of the mounting roller shaft used in current static elimination equipment is fixed. When it is necessary to fix center rollers with different diameters, it is necessary to replace the corresponding mounting roller shaft, and the disassembly and assembly of the mounting roller shaft are not convenient and fast enough, which affects normal processing operations. Summary of the Utility Model

A clamping mechanism for quick disassembly is provided between the mounting roller shaft and the columns, and an extrusion fixing mechanism is provided inside the mounting roller shaft.

[0008] Furthermore, the clamping mechanism includes sliding grooves opened on both sides of the top of the column. The inner wall of the sliding groove is slidably connected with clamping blocks. A pull rod is fixed to the outer end of the clamping block. The pull rod penetrates through the sliding groove and extends to the outside of the column. A spring is sleeved on the surface of the pull rod, and both ends of the spring are in contact with the clamping block and the sliding groove respectively.

[0009] Furthermore, guide bars are fixed to both the front and rear sides of the clamping block, and guide grooves are opened on the inner wall of the sliding groove. The guide bars are slidably connected with the guide grooves.

[0010] Furthermore, the extrusion fixing mechanism includes a number of grooves opened on the surface of the mounting roller shaft. The inner side of the groove is slidably connected with a concave plate. A number of threaded sleeves are fixed to the inner side of the concave plate. A threaded rod is rotatably connected through the bottom of the groove. A transmission component for simultaneously driving the concave plate to extrude outward is provided between the threaded rod and the mounting roller shaft.

[0011] Furthermore, the transmission component includes a circular cavity opened inside the mounting roller shaft. A rotating rod is rotatably connected to the inner wall of the circular cavity. Transmission bevel gears are fixed to both sides of the surface of the rotating rod. The inner end of the threaded rod penetrating through the groove is fixed with a driven bevel gear. The driven bevel gear is meshed with the transmission bevel gear. One end of the rotating rod penetrates through the circular cavity and extends to the outside of the mounting roller shaft.
