[0011] Furthermore, the threaded protrusion is a rubber protrusion.

[0012] The beneficial effects of the utility model are:

[0013] 1. The position of the adjusting shaft is adjusted by sliding the adjusting shaft in the sliding hole, thereby adjusting the tension of the film body, thereby preventing the film body from wrinkling, so as not to affect the winding effect of the polyester film.

[0014] 2. The leveling shaft is driven to rotate by the driving motor and the meshing of the two bevel gears, thereby driving the threaded protrusion to rotate, thereby leveling the film body and improving the winding efficiency of the polyester film.

[0015] 3. By pulling the limit plate to move on the adjustment shaft, the distance between the two limit plates is adjusted to limit the two sides of the film body with different widths. BRIEF DESCRIPTION OF THE DRAWINGS

A first guide roller 2 and a second guide roller 3 are rotatably connected between the inner walls on both sides of the mounting frame 1 through bearings. The film body 18 is wound around the first guide roller 2 and the second guide roller 3. A fixing plate 4 is welded between the inner walls on both sides of the mounting frame 1. A leveling shaft 5 is rotatably inserted between the inner walls on both sides of the mounting frame 1 and the fixing plate 4 through bearing seats. A bevel gear 7 is keyed at one end of the leveling shaft 5. The two bevel gears 7 are meshed. A threaded protrusion 6 is fixed to the outer wall of the leveling shaft 5 by bolts. A mounting plate 8 is welded to the outer wall of one side of the mounting frame 1. A driving motor 9 is fixed to the top of the mounting plate 8 by bolts. The drive motor 9 The output end is key-connected with one end of one of the leveling shafts 5. The leveling shaft 5 is driven to rotate by the driving motor 9 and the meshing of the two bevel gears 7, thereby driving the threaded protrusion 6 to rotate, and then leveling the film body 18. Slide holes 10 are provided on both sides of the mounting frame 1. An adjusting shaft 11 is slidably connected between the two slide holes 10.
