Abstract

The invention discloses a double-welding-edge plastic thin film production line. The double-welding-edge plastic thin film production line comprises a base, stand columns, a first transverse plate anda second transverse plate, wherein the four corners of the interior of the first transverse plate and the four corners of the interior of the second transverse plate are fixedly connected with the base through the stand columns, a winding and unwinding roller assembly is installed on the left side and the right side of the upper portion of the base, the winding and unwinding roller assembly comprises a first vertical plate, a first rotating shaft, a first material roller, a second material roller, a winding roller and a second vertical plate, and the upper portion of the interior of the second vertical plate is rotationally connected with the winding roller through the first rotating shaft. The double-welding-edge plastic thin film production line is scientific and reasonable in structureand safe and convenient to use, a motor, a first belt, a second belt, a third belt, second pressing rollers, the winding roller, a nut, a spring and a third pressing roller are arranged for cooperation, a user can start the motor and a laser welding head at the same time, so that it is guaranteed that the surface tension of a thin film is sufficient during winding after forming, and the situationthat in the prior art, when a double-welding-edge thin film is machined, insufficient tension is prone to occurrence, and consequently the winding effect is poor is avoided.

Description

technical field [0001] The invention relates to the technical field of plastic films, in particular to a double-welded plastic film production line. Background technique [0002] Plastic film, film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, used for packaging, and as a coating layer, the market share of plastic packaging and plastic packaging products is increasing It is getting bigger and bigger, especially for composite plastic flexible packaging. During the processing of plastic films, double welding edges are often required. Although the existing technology can realize double-sided welding of plastic films, the existing technology exists in the double welding edge Insufficient tension is prone to occur during film processing and the winding effect is poor. At the same time, there is still the problem that the film needs to overcome the resistance and inconvenient installation when the film is reloaded and stretched to pass thro...
