Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] like Figure 1-2 This is a schematic diagram of the structure of a winding roller for iridescent film according to a preferred embodiment of the present invention. In this embodiment, a winding roller for iridescent film includes a roller frame 1. A connecting hole 2 is provided in the middle of the surface of the roller frame 1. A rotating shaft 3 is inserted into the connecting hole 2. The rotation of the rotating shaft 3 drives the roller frame 1 to rotate. Multiple irregular grooves 5 are provided around the connecting hole 2 on the surface of the roller frame 1. A roller block 4 is connected to one end of the roller frame 1 through the irregular groove 5. The spacing between the roller blocks 4 can be adjusted by the irregular grooves 5. At the same time, multiple guide blocks 31 are fixedly connected to the surface of the rotating shaft 3 at the relative position of the roller blocks 4. A connecting block 41 is fixedly connected to the inner wall of the roller block 4 at the relative position of the guide blocks 31. A guide groove 43 is provided on the surface of the connecting block 41, and the inner wall of the guide groove 43 is movably connected to the outer wall of the guide block 31, which plays a guiding role in the process of adjusting the spacing of the roller blocks 4 in the irregular grooves 5, and at the same time increases the ability of the rotating shaft 3 to drive the roller blocks 4 to rotate during the rotation process.

[0019] In this embodiment, the rear end of the roller block 4 is fixedly connected to a threaded rod 42, and the threaded rod 42 is movably connected to the irregular groove 5. A connection position 51 is provided at the groove opening of the irregular groove 5 away from the roller block 4. A nut 6 is provided in the connection position 51. The nut 6 is threadedly connected to the threaded rod 42, so that the roller block 4 is fixed on the roller frame 1.

[0020] Working principle

[0021] In actual operation, before the iridescent film starts to be wound up, slide the threaded rod 42 to the highest point of the irregular groove 5 and tighten it with the nut 6 to adjust the gap between the roller blocks 4 to the maximum; then put the winding drum of the iridescent film onto the surface of the roller block 4; after the iridescent film is wound up, slide the threaded rod 42 to the lowest point of the irregular groove 5 and tighten it with the nut 6 to smoothly pull out the winding drum of the iridescent film after it has been wound up.
