Reciprocating continuous film pressing apparatus

Abstract

The invention discloses a reciprocating continuous film pressing apparatus, which belongs to the field of a film processing mechanical device. One end of a reciprocating piston rod on an output end ofa reciprocating air cylinder is hinged with the middle of a reciprocating rod, a translation connecting rod is obliquely arranged between a lower translation plate and a reciprocating swinging rod, the lower side of a reciprocating rotating barrel is horizontally connected with a rotating base in a rotating manner, an annular rack plate is horizontally fixedly arranged at the outer side of the middle of the reciprocating rotating barrel, the translation rack plate on the lower side of the upper translation plate is in engaged connection with the annular rack plate, two sides of a film pressing guide rod are respectively and successively provided with a front reciprocating bearing plate and a rear reciprocating bearing plate along the horizontal direction, the output end of a front film pressing air cylinder is vertically connected with a front film pressing roller in a rotating manner, and the output end of a rear film pressing air cylinder is vertically connected with a rear film pressing roller in a rotating manner. The reciprocating continuous film pressing apparatus is reasonable in structure design, capable of realizing the film pressing in a large-stroke reciprocating continuous movement manner, capable of adjusting a film pressing angle according to the compositing requirement of a film, and capable of meeting the production and application requirements.

Description

technical field [0001] The invention belongs to the field of film processing machinery and equipment, and in particular relates to a reciprocating continuous film lamination device, which is mainly used for film lamination composite processing of film strips. Background technique [0002] 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, cooking food Packaging, fast food packaging, etc., these have brought great convenience to people's lives. Film strips are widely used in our daily life and industrial production. Film strips can ...

AI Technical Summary

Problems solved by technology

Film strips are widely used in our daily life and industrial production. Film strips can be used as packaging materials and sealing materials. Film strips with better performance can also be used as packaging materials for wire harnesses. Therefore, during processing and use , in order to improve the performance of the film strip, the surface of the film strip needs to be coated with glue, and two or more layers of film strips are compounded. In the process of film strip compounding, the commonly used method is to use the transmission mechanism to The film strips are conveyed, and two film guide rollers are used to compress each other during the transmission of the film strips so that the film strips can be compressed and compounded. , it is easy to cause two or more layers of film strips to be difficult to be fully and efficiently compressed and compounded, and even if multiple sets of film guide rollers are used to compress each other in sequence during the film compounding process, it is difficult to fully and efficiently compress the film strips Fully compress and compound, and in the process of film compression and compounding, the air between two adjacent layers of films is difficult to be fully and conveniently discharged, resulting in bulges between the films after compound processing due to the presence of air, which affects the film The quality of composite processing reduces the efficiency and quality of film composite processing, which cannot meet the needs of production and use
