Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, specifically a film cutting and rolling machine. Background Technology

[0002] Adhesive film is a thin, sticky material, usually made of high molecular polymers. Adhesive films can be classified according to their material into plastic films, rubber films, paper films, etc., and according to their adhesion into pressure-sensitive films, hot melt films, water-based films, etc. They have a wide range of applications in many fields.

[0003] Because of its adhesive properties, a release film is usually attached to the adhesive film during production to prevent it from sticking together after being rolled up and left to stand for too long, which would render it unusable. Before using the adhesive film, it is necessary to separate the adhesive film from the release film.

[0004] Currently, slitting machines used to separate adhesive film and release film generally use two winding rollers that are far apart to wind up the adhesive film and release film respectively, and use the tension generated during winding to separate the adhesive film and release film. However, the above separation method relies solely on the tension generated during winding, and the force is difficult to control, which can easily lead to tearing of the adhesive film or release film, resulting in damage to the adhesive film and rendering it unusable.

With the tension generated during the winding of the front winding structure 2, the slitting winding structure 3 and the rear winding structure 4, the adhesive film 5 and the release film can be separated quickly. Moreover, the cutting of the separating blade 801 can reduce the impact of the tension on the adhesive film 5 and prevent the adhesive film 5 from tearing.

[0052] Two drive rollers 901 can move the film 5 to the space between the slitting roller 101 and the rotating roller 102. When the film 5 needs to be cut into multiple pieces, the cylinder 107 drives the rotating plate 105 to rotate around the connecting rod 106, thereby bringing multiple cutters 103 closer to the slitting roller 101 and cutting the film 5 into multiple pieces. The slitting and winding structure 3 then winds up the cut film 5. When the film 5 does not need to be cut, the cylinder 107 drives multiple cutters 103 away from the slitting roller 101, and the rear winding structure 4 winds up the complete film 5. This allows for different processing of the film 5 according to the specific working conditions, thus improving its applicability.
