Description

Technical Field

[0001] This utility model relates to the field of reflective film processing, and in particular to a winding device for reflective film processing. Background Technology

[0002] Reflective film is a pre-made thin film that can be directly applied as a retroreflective material. It is made using a variety of technologies such as glass bead technology, microprism technology, synthetic resin technology, thin film technology, and coating technology. The winding device for reflective film processing is a type of equipment specifically used on reflective film production lines. It is mainly used to wind, rewind, and package the produced reflective film for storage, transportation, and use.

[0003] According to Chinese Patent Publication No. CN222699667U, a winding device for processing reflective film includes a worktable, an adaptive tension mechanism, and a guiding mechanism. The worktable has uniformly distributed conveyor rollers rotatably connected inside. Symmetrically distributed supports are fixedly connected to the upper end of the worktable. Drive rollers are rotatably connected between horizontally adjacent supports, and each drive roller corresponds vertically to a vertically adjacent conveyor roller. A winding frame is provided on the front side of the worktable, and a winding roller is rotatably connected to the upper end of the winding frame. Although the tension during the winding process of the reflective film can be adjusted through the adaptive tension adjustment mechanism, the winding roller connected to the winding frame only bears force at one end. During the winding process of the reflective film, as the winding thickness increases, the weight continuously increases, causing the winding roller to oscillate, thus causing unstable winding. Therefore, we propose a winding device for processing reflective film to solve the above problems. Utility Model Content
