Film bundling method

Technical Field

The invention relates to the technical field of film bundling devices, in particular to a film bundling method.

Background

The food package generally uses plastic package bags as main products, and is mainly made of plastic, adhesive, rubber or other materials. The scientific explanation of the polyester film is as follows: the 2-dimensional material formed by depositing atoms, molecules or ions on the surface of a substrate, before bag making, plastic packaging bags mostly comprise the following production process flows: printing (coating ink on the surface of a printing plate, transferring the pictures and texts on the printing plate to the surface of a material to be printed by pressure) → compounding (bonding two or more layers of materials together by media (such as glue)) → curing (accelerating the curing speed of the glue between the materials), so that the plastic film for the packaging bag can be formed, and then the roll separating operation can be carried out. The roll dividing operation is to divide the cured big roll of the plastic film into a plurality of small rolls so as to facilitate the subsequent bag making operation of a client manufacturer.

At present, a plurality of films which are just produced are generally in a large roll and have long length, and the film roll dividing device can divide the long films into small rolls and then package and sell the small rolls; most of the existing film bundling devices do not clean the film before bundling, so that a little dust still exists on the surface of the film, the sanitation degree of the film is reduced, the quality of a product is reduced, the film is cut manually, the traditional manual operation is low in efficiency, the manual judgment error is large, the cut film is different in length and influences normal use, the tension control of the film is particularly important when the film is wound, if the tension is large, the film is likely to deform and loose, the film is wound and distributed unevenly, wrinkles are likely to occur, and the later-stage processing is seriously influenced.

Through the retrieval, the patent of publication number CN108745980A discloses a film bundling device, including the base, be equipped with strutting arrangement on the bottom lateral wall of base, the last lateral wall fixedly connected with bundling machine body of base the last lateral wall of base is equipped with rotating device, the upside of base is equipped with conveyer, conveyer is located between rotating device and the bundling machine body, the last lateral wall of base is equipped with cleaning device, cleaning device includes the mounting panel, fixedly connected with first motor in the mounting panel. According to the invention, the output shaft is driven to rotate by the first motor, so that the roller is driven to rotate, the connecting rod is driven to rotate, and the cleaning brush is driven to rotate, so that the surface of the film can be cleaned, the dust on the surface of the film can be conveniently cleaned, and the sanitation degree of the film is improved. The film bundling device in the patent uses the roller to drive the cleaning brush to clean the surface of the film when the film is cleaned, only one side can be cleaned in the process, the cleaning effect is poor, the film surface is easy to scratch due to slight cleaning, the subsequent process is influenced, the film is easy to scratch seriously, the film is damaged, the bundling work cannot be carried out, and the problems of clipping and tension adjustment are not considered, so the film bundling device has the defects.
