Description

Technical Field

[0001] The utility model relates to the field of protective film production, in particular to a protective film processing and gluing device. Background Art

[0002] Protective film is used to cover and protect products and is widely used in the packaging field. When the protective film is produced, its surface needs to be coated with glue, and the glue is evenly applied on the surface of the protective film using a glue coating machine.

The bristles 34 are evenly distributed and fixed on one side of the lower surface of the movable plate 32. As the protective film moves, the bottom end of the bristles 34 cleans the dust on the upper surface of the protective film. The upper surface of the stopper 35 is fixedly connected with the other side of the lower surface of the movable plate 32. The stopper 35 is V-shaped, and the tip of the stopper 35 is set at the back position. The lower surface of the stopper 35 is in contact with the upper surface of the protective film. The stopper 35 is used to clean the dust. The dust behind is blocked, so that the dust impurities move to both sides along the inclined surface of the stopper 35, which is convenient for cleaning the dust impurities. The compression spring 36 is movably sleeved with the bottom of the connecting rod 33. The compression spring 36 is arranged between the top of the inner wall of the fixing frame 31 and the upper surface of the movable plate 32. The elastic action of the compression spring 36 pushes the movable plate 32 downward, so that the bristles 34 and the stopper 35 are closely attached to the upper surface of the protective film. The two ends of the carrying plate 37 are fixedly connected to the two sides of the inner wall of the fixing frame 31. The carrying plate 37 is arranged below the movable plate 32.
