Film unwinding device

The utility model provides an unwinding device for a thin film. The unwinding device comprises a frame body, an unwinding roller and a flattening mechanism, wherein the surface of the unwinding roller is wound with the thin film; the unwinding roller is rotatably connected to the frame body so as to output a thin film wound on the surface of the unwinding roller outwards through self rotation, and the flattening mechanism is arranged on an output path of the thin film and attached to the surface of the thin film so as to flatten the surface of the thin film. The surface of the film can be prevented from wrinkling in the unwinding process of the film, so that the working effect is guaranteed. 本实用新型提供一种薄膜的放卷装置，包括：架体、表面缠绕有薄膜的放卷辊、展平机构；放卷辊可转动连接在架体上，以通过自身旋转将缠绕在其表面的薄膜向外输出，展平机构设置在薄膜的输出路径上，并贴合在薄膜的表面上，以将薄膜的表面展平。其能够在薄膜的放卷过程中，避免其表面出现褶皱，使工作效果得到保证。
