Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag processing, in particular to a solvent-free composite device. Background Art

[0002] When packaging bags are produced and processed, multiple sets of plastic films are usually selected for composite pasting, and the characteristics of different plastic films are used to make the packaging bags meet the actual use requirements. When the packaging film is composited, a solvent-free composite device is often used for composite processing.

[0003] The common solvent-free composite device currently available on the market adheres the solvent-free glue in the container through a glue roller, then transfers the glue to the glue coating roller through a glue transfer roller, and the glue coating roller coats one side of the film. Then, the glue-coated sides of the two groups of films are bonded together. However, in actual use, when the glue roller comes into contact with the solvent-free glue inside the container, as the glue is continuously consumed, the liquid level drops, making it impossible for the glue roller to come into contact with the glue. Therefore, a liquid level sensor and an automatic glue adding mechanism need to be provided to achieve this, which is costly, and there is always a large amount of glue in the container. Long-term exposure may cause the glue to dry out and solidify. Therefore, a solvent-free composite device is provided to solve the above problems. Utility Model Content

A liquid level sensor and an automatic glue adding mechanism need to be provided to achieve this, which is costly.
