Gluing mechanism of film compound machine

Abstract

The invention discloses a gluing mechanism of a film compound machine, and belongs to the field of film production equipment. A rack is included and provided with a glue feeding material groove for containing glue. The rack is rotationally provided with a glue feeding roller with the outer circumference wall making contact with glue. The rack is provided with a uniform scraping mechanism and a material storage barrel. A communication pipe is in communication between the material storage barrel and the glue feeding material groove. The end, close to the material storage barrel, of the communication pipe is provided with a feeding port, and the other end is provided with a discharging port. The material storage barrel is internally in up-down sliding connection with a sliding seal plate forsealing the feeding port. The sliding seal plate extends out of the material storage barrel. The material storage barrel is provided with a through groove for the sliding seal plate to penetrate. Theouter wall of the sliding seal plate and the inner wall of the through groove are in seal fit. The upper end of the material storage barrel is provided with a charging port and a plug for sealing thecharging port. The gluing mechanism of the film compound machine can automatically conduct charging on the interior of the glue feeding material groove, and workers can conveniently conduct operation.

Description

technical field [0001] The invention relates to the technical field of film processing machinery, in particular to a gluing mechanism of a film laminating machine. 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 cover the surface of the fil...

Problems solved by technology

[0004] Although the above-mentioned rubber roller scraping mechanism on the film is equipped with a scraping mechanism on the fixed bracket, so that the gluing can be more uniform, there is still a problem in the rubber roller scraping mechanism on the film: the upper rubber roller is constantly rotating. During the film gluing process, the amount of glue in the sizing tank will gradually decrease, the liquid level of the glue will gradually decrease, the contact area between the glue and the gluing roller will also gradually decrease, and the glue in the sizing tank will gradually decrease Finally, the amount of glue adhered to the upper rubber roller will also decrease. When the glue liquid level drops to a certain height, although the upper rubber roller can still contact the glue in the sizing tank, it cannot evenly coat the film. Glue, so it is often necessary to manually pour glue into the glue tank to ensure that the glue level in the glue tank will not be too low. If it is too low, it will affect the effect of gluing the film, so the staff operate It's more troublesome to get up
