Thin film conveying gluing device

Abstract

The invention discloses a thin film conveying gluing device and belongs to the field of thin film processing equipment. The thin film conveying gluing device comprises a main support, a film guide mechanism, a film gluing mechanism and a film discharging mechanism, wherein the film guide mechanism, the film gluing mechanism and the film discharging mechanism are sequentially arranged on the main support in the thin film conveying direction. The film guide mechanism comprises a first film guide roller, a second film guide roller, a third film guide roller and a fourth film guide roller, wherein the first film guide roller, the second film guide roller, the third film guide roller and the fourth film guide roller are sequentially connected to the main support horizontally and rotationally in the thin film conveying direction. A static electricity eliminating board is arranged between the first film guide roller and the second film guide roller. A tension adjusting roller is arranged between the second film guide roller and the third film guide roller. The film gluing mechanism comprises a film pressing mechanism, a gluing roller, a glue feeding roller and a film gluing groove, wherein the film pressing mechanism, the gluing roller, the glue feeding roller and the film gluing groove are sequentially arranged from top to bottom. The surface of the gluing roller is attached to the surface of the glue feeding roller. The film gluing groove is an arc-shaped groove matched with the glue feeding roller in shape. The film discharging mechanism comprises a driving motor, a driving shaft, a driving screw and a film discharging roller. The thin film conveying gluing device is simple in structure, thin films can be glued rapidly, efficiently and evenly, and the requirement for production is met.

Description

technical field [0001] The invention relates to a gluing device, in particular to a film conveying gluing device, which belongs to the field of film processing equipment. 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, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical industry 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., all of which have brought great convenience to people's lives. During the production and processing of the existing film, it is necessary to coat a layer of glue ...

AI Technical Summary

Problems solved by technology

During the production and processing of the existing film, it is necessary to coat a layer of glue on the surface of the film so that the two layers of film can be tightly bonded by glue to form a composite film. The existing film conveying and coating device has a complicated structure and cannot be quickly and efficiently The film is evenly coated with glue, and the tension of the film cannot be adjusted conveniently during the conveying process, resulting in damage to the film due to excessive tension, and the existing film conveying device is not equipped with a static removal device, resulting in the film being in the process of conveying Static electricity cannot be efficiently removed during the process. During the feeding process of the existing trough, the glue often deposits in the trough, which makes the quality of the glue in the trough uneven. The existing trough generally adopts single-port feeding , no return pipe is set, as the film continues to be glued, the viscosity of the glue in the trough changes, which reduces the overall viscosity uniformity and stability of the feed liquid in the trough, and affects the coating of the film. The existing film The conveying gluing device only simply sets a laminating roller, and the position of the laminating roller cannot be precisely adjusted according to the needs of film gluing, and the distance between the laminating roller and the gluing roller cannot be precisely controlled, so that the glue cannot be evenly distributed. Applied on the surface of the film, it affects the fast and efficient uniform coating of the film, reduces the production quality of the film, and cannot meet the needs of production

[0003] The invention patent with application number 201220350618.7 provides a four-roller gluing device for a gluing machine, which includes two parts, an upper gluing unit and a lower gluing unit. Composed of rubber rollers, glue spraying tubes, etc., the rotation direction of the upper and lower rubber rollers is consistent with the advancing direction of the paper tape, the upper extrusion rubber roller and the upper rubber roller rotate oppositely, the lower extrusion rubber roller and the lower rubber roller rotate oppositely, The gap between the gluing roller and the extrusion roller can be adjusted separately. Although the amount of glue applied to the film can be controlled by controlling the gap between the gluing roller and the extrusion roller, it cannot ensure that the glue can be applied accurately and evenly on the surface of the film, and it is difficult to ensure that the film The quality of gluing cannot meet the needs of film gluing
