[0002] Composite film refers to a multi-layered film formed by combining various plastics with paper, metal or other materials through lamination, extrusion coating, co-extrusion and other process technologies to combine the substrate. It is generally composed of substrate, lamination adhesive, barrier material, heat sealing material, printing and protective layer coating, etc. In the composite film process, the structure of a multi-layer composite material is usually expressed in abbreviated form. For example, a typical pharmaceutical composite film can be expressed as: surface layer / printing layer / composite layer / aluminum foil / adhesive inner layer. Composite film refers to a separation membrane with a microporous membrane or ultrafiltration membrane as a support layer and a dense homogeneous membrane with a thickness of only 0.1 to 0.3 microns as a barrier layer on its surface. Due to its high barrier properties, composite membranes are widely used in the field of pharmaceutical packaging.

[0003] In the production process of composite film, a winding device is required to wind up the composite film, so as to facilitate subsequent transportation and use. However, the common winding devices on the market have the following problems during use: 1. When winding, it is often difficult to fix the starting end of the composite film, which makes it difficult to start winding, greatly reducing the winding efficiency; 2. It is not convenient to adjust the tension of the winding, and it is not convenient to avoid wrinkles during the winding process, which affects the winding efficiency.
