TECHNICAL FIELD
[0001] The utility model relates to a film blowing machine technical field, specifically a film blowing machine traction roll cooling device. BACKGROUND
[0002] The film blowing machine is the processing equipment that blows into the film after granular material heating melts, and the film blown out of the die head and the air ring is usually the cylindrical film, then gets the sheet film finished product after the herringbone plate, and is finally rolled up by the winding machine. However, the current film blowing machine generally cools the film through the air ring, and the film cooling is insufficient, which easily causes the film to stick after extruding and rubbing through the traction roll and the embossing roll. The traditional solution is to add an opening agent to the film to solve the film sticking problem. However, the opening agent generally has different degrees of side effects, such as a large amount of precipitates on the film surface, affecting the printability, heat sealability, and color of the film; at the same time, it also has a certain impact on the internal packaging.
[0003] Therefore, we designed the film blowing machine traction roll cooling device, which combines the design concept of the traditional casting machine, and designs the traction iron roll and the embossing iron roll on the film blowing machine as water-cooled rolls. When guiding and embossing the film, it can effectively cool the film, solve the problem of film sticking after rolling, and make the film unnecessary to add an opening agent during production, thereby improving the finished product quality of the film.
