Material guiding and processing mechanism for thin film

Abstract

The invention discloses a material guiding and processing mechanism for a thin film, and belongs to the field of thin film processing technology equipment. The mechanism comprises a material guiding bracket, a winding roller, a rotating bracket, a tensioning cylinder, an unwinding bracket, a unwinding roller, a thin film fixing mechanism, a gluing mechanism and a film pressing composite mechanism, wherein the unwinding bracket, the rotating bracket and the winding roller are sequentially arranged on one side of the material guiding bracket from top to bottom, the thin film fixing mechanism is horizontally arranged at the upper end of the other side of the material guiding bracket, the gluing mechanism is horizontally arranged at the lower end of the material guiding bracket, the winding roller is horizontally arranged on the upper side of the material guiding bracket, a rotating main roller is horizontally and rotationally connected to the upper side of the rotating bracket, the unwinding roller is horizontally and rotationally connected to the upper side of unwinding bracket, and one side of the material guiding bracket is sequentially, horizontally and rotationally connected with an upper material guiding roller and a lower material guiding roller from top to bottom. The mechanism is reasonable in structural design, can be used for unwinding and winding the thin film, synchronously, stably and accurately and can carry out coating and compound processing in the film conveying process, and the requirements of production and use are met.

Description

technical field [0001] The invention belongs to the field of film processing technical equipment, and in particular relates to a film guide processing mechanism. Background technique [0002] At present, films are more and more widely used in our production and life. Films are generally made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, used for packaging and as a coating layer , plastic packaging and plastic packaging products are taking an increasing share in the market, and have been widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging, quick-frozen food packaging, Cooked food packaging, fast food packaging, etc., have brought great convenience to people's lives. During the production and processing of the existing film, in order to obtain more excellent performance of the film, it is necessary to carry out composite processing of two or mor...

AI Technical Summary

Problems solved by technology

During the production and processing of the existing film, in order to obtain more excellent performance of the film, it is necessary to carry out composite processing of two or more layers of film, so that the film can have excellent heat sealing, airtight and mechanical properties. The existing film In the process of material guide processing, independent unwinding mechanism and winding mechanism are generally used to unwind and rewind the film respectively. The tension will change, and a tension adjustment mechanism is required to adjust the tension of the film conveniently. The structure is complex and the operation is troublesome, and the existing film guide mechanism is difficult to press and fix the film according to the needs of use during the transmission process. It is easy to cause damage to the film surface during the film fixing process. The existing film gluing mechanism generally uses two rubber rollers arranged from top to bottom to process the film surface, making it difficult to accurately apply the amount of glue on the film surface. control, which reduces the efficiency and quality of film guide processing, and cannot meet the needs of production and use
