Description

Technical field:

[0002] The utility model relates to a packaging film gluing device for a packaging bag. Background technology:

[0004] The basic principle of composite flexible packaging of packaging bags is that since each material has different advantages and disadvantages, two or more layers of materials are bonded together through a medium (such as glue) to make the packaging film and bag achieve better performance. This technology is called "composite process" in the production process.

[0005] At present, in the process of packaging bag production, it is necessary to glue the inner surface of the packaging film before sending it to the next process. When gluing the inner surface of the packaging film, the packaging film is usually passed between a rubber roller whose lower end is immersed in a glue tray and a pressure roller, and the inner surface of the packaging film is glued by the rubber roller. In the gluing process, it is usually necessary to set a scraper or scraper board on the surface of the rubber roller to keep the glue on the rubber roller within a certain range.

[0006] However, in the existing gluing equipment, the scraper blade or scraper plate is mostly a fixed structure, which is not convenient for position adjustment or the adjustment is rather cumbersome; and the width of the packaging film is different. During the production process, it is necessary to glue the packaging films of different widths. Therefore, how to conveniently adjust the position of the scraper blade or scraper plate to adapt to the gluing of packaging films of different widths has become a technical problem that needs to be solved urgently, and this case is born out of this.
