[0002] The film is used to roll up the processed film, which is convenient for subsequent processing, transportation or storage of the film. For example, a film winding machine proposed in the Chinese patent with patent announcement number CN206126403U includes a winding frame, a conveying shaft, a winding shaft and a film pressing frame. The winding frame is placed through the chassis, and a roller is provided on one side of the chassis below the winding frame. A film shaft is provided on one side of the winding frame, and a roll of film is rolled on the film shaft. Several conveying shafts are installed on the winding frame through a movable seat, and a screw is provided below the conveying shaft. The end of the screw is connected to a handwheel, and a limit block is threadedly connected to the screw. The limit block is sleeved on the track. A transmission shaft and a driven wheel are provided on one side above the winding frame. The transmission shaft is connected to the motor.
