Background Before gypsum boards leave the factory, a layer of protective film (film) is generally required to be wound on the surface of the gypsum board so as to facilitate subsequent integral packaging and transportation, and when the existing winding film packaging machine starts to wind the film, the free end of the film is generally fixed, so that the free end is prevented from rotating along with the packaging machine, and the winding action is prevented from being invalid. At present, a common mode of fixing the free end of the film is generally vacuum adsorption, a vacuum generator is configured to provide a vacuum environment, and the free end of the film is adsorbed by a vacuum chuck connected with the vacuum generator, so that the free end of the film is kept in a fixed state before winding begins. However, the vacuum suction structure is greatly affected by the surface state of the film, and when the film is wrinkled, slightly broken, rough in surface or stained with dust, it is difficult to form a reliable seal between the vacuum chuck and the film, resulting in a significant decrease in suction force and insufficient fixability.
