Film coating process for manufacturing packaging container

Abstract

The invention provides a film coating process for manufacturing a packaging container. The film coating process comprises a winding mechanism, a coating mechanism, a guide mechanism, a drying mechanism, a conveying mechanism, a main beam plate frame, a guide roller I and a guide roller II. The film coating process solves the problems that clamping and fixing of an unwinding winding drum and a winding drum have limitation at present, and winding drums with different types and sizes cannot be clamped, so that the manufacturing of the film coating process is relatively single, and production and processing of film coating processes with different sizes cannot be realized; in the winding and unwinding processes, the execution actions cannot be synchronized, the tension in the film coating process is influenced to be constant, the film transmission stress is unbalanced, and the film is wrinkled or torn; no guide motion track exists for the transmission of paper printed matters and films, the deviation condition is easily caused after the films and the paper printed matters are compounded, and the film coating quality is influenced; and the coating of an adhesive on the surfaces of the films cannot be uniformly controlled, the coating flow speed of the adhesive cannot be controlled, and the film coating process is influenced.

Description

technical field [0001] The invention relates to the technical field of film coating for packaging containers, in particular to a film coating process for packaging containers. Background technique [0002] Packaging containers generally refer to the general name of packaging devices, materials and other auxiliary materials used in accordance with certain technical specifications in order to protect commodities, facilitate storage, facilitate transportation, promote sales, prevent environmental pollution and prevent safety accidents in the process of commodity circulation. ;Packaging containers are the combination of packaging materials and shapes, including packaging bags, packaging boxes, packaging bottles, packaging cans and packaging boxes, etc.; [0003] The commonly used materials for packaging boxes are: white cardboard, kraft paper, coated paper, special paper, etc. When making packaging boxes, merchants usually print patterns and advertising slogans on the packaging...

AI Technical Summary

Problems solved by technology

[0004] Nowadays, the following problems often exist in the lamination process of paper printed matter: the clamping and fixing of the unwinding reel and the rewinding reel has limitations, and the reels of different models and sizes cannot be clamped, which makes the production of the lamination process relatively simple. The production and processing of lamination processes of different sizes cannot be realized; and in the process of winding and unwinding, the execution actions cannot be synchronized, which affects the constant tension in the lamination process, makes the film transmission unbalanced, and easily causes wrinkles or tearing; and there is no guiding movement track for the transmission of paper prints and films, which may easily lead to deviations after the film and paper prints are compounded, affecting the quality of the film; the coating of the adhesive on the film surface cannot be uniformly controlled, and cannot be controlled The coating flow rate of the adhesive has a negative impact on the coating process; for this reason, the invention provides a packaging container making coating process
