The front of the locking block 20 extends through the interior of the slider 18.
[0034] As a technical optimization of this utility model, the filter mechanism 14 can filter the incoming air and prevent impurities from being drawn into the heating box 5.
[0035] refer to Figure 3 The heating box 5 has a movable groove 21 on both sides of the rear side, and the inner side of the movable plate 19 is slidably connected to the inside of the movable groove 21.
[0036] As a technical optimization of this utility model, the movable groove 21 enables the movable plate 19 to slide more smoothly inside the heating box 5, reducing friction between the movable plate 19 and the heating box 5 and extending the service life of the movable plate 19.

When the locking block 20 on the front of the moving plate 19 is aligned with the locking groove 22 on the back of the slider 18, continue to push the moving plate 19 so that the locking block 20 is engaged in the locking groove 22, thereby fixing the filter mechanism 14. Then, the heating block 6 at the bottom of the inner cavity of the heating box 5... When the machine starts working, heat is generated by the heating column 7 connected by electricity and the heating wire 8 wrapped around the surface of the heating column 7. At the same time, the blower 11 on the top of the ventilation plate 9 is started, drawing in outside air from the air inlet 10 at the bottom of the heating box 5. After being filtered by the filter mechanism 14, the air enters the interior of the heating box 5 and is heated by the heating wire 8 to form hot air. The hot air is delivered to the air diffuser 13 on the front of the film winding assembly 3 through the air duct 12 and blown out evenly from the air diffuser 13 to heat the film to be wound, achieving the effect of preheating and eliminating static electricity.
[0044] In summary, this improved coreless winding film machine changes the traditional phenomenon where static electricity easily attracts dust and impurities to the film surface. It uses heating block 6 to heat heating column 7 and heating wire 8, and then the heat is blown onto the film surface through air duct 12, which can remove static electricity and prevent external dust and impurities from adhering to its surface, thus improving the quality of the finished product.
