Abstract

The invention discloses a heat-shrinkable film blowing unit, which comprises a hot-melt machine, a heating element, a film tube and a herringbone plate. The top of the hot-melt machine is welded with a hopper, and the middle bolt of the first bracket is fixed with a film pipe, and the top of the first bracket is welded with a herringbone plate, one end of the guide cylinder is connected with an air duct, and one end of the air duct is located outside the first bracket, and the side bolts of the first bracket are connected with the second Two brackets, and the top edge of the second bracket is welded with a winding roller assembly, the upper end of the second bracket is welded with a mounting frame, and the mounting frame is located between the winding roller assembly and the first frame, the bottom of the mounting frame The inner shaft of the is connected with a guide roller. The heat-shrinkable film blowing unit removes metal substances in raw materials during the feeding stage, guides and synchronously cools the film during the forming stage, and flattens the film during the winding stage to avoid wrinkles.

Description

technical field [0001] The invention relates to the technical field of heat shrinkable film production, in particular to a heat shrinkable film blowing unit. Background technique [0002] Heat shrinkable film is a kind of transparent thermoplastic film. Because of its high puncture resistance, good shrinkage and certain shrinkage stress, it is mostly wound on the surface of objects to protect the goods. Heat shrinkable film is used in the production process. In the process, the granular raw materials are hot-melt extruded, then blow-molded, and then rolled, and the whole is processed by an integrated blown film unit. However, the existing blown film unit has the following problems in use: [0003] The film blowing unit involves the pouring, hot melting and extrusion of raw materials. If metal substances enter it, it will cause wear to the unit and reduce the quality of film formation. The metal substances in the raw materials need to be removed; [0004] In the film forming...
