Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag processing, in particular to a drying device for gluing paper packaging bags. Background Art

[0002] Packaging bags are used to pack various items, making it easy to transport and store goods during production and circulation. At present, packaging bags have been widely used in all walks of life and are suitable for packaging goods of various shapes. The sealed and packaged goods are hygienic, clean, dust-proof and moisture-proof, and can also give the products good protection performance.

[0003] After gluing, the surface of paper packaging bags needs to be dried to prevent the glue on the surface of the paper packaging bags from flowing and affecting their use. In order to ensure the smoothness of paper packaging bag transportation, existing drying equipment mostly uses conveyor belt transportation. The side of the paper packaging bag close to the conveyor belt is directly in contact with the conveyor belt, and it is not easy to directly contact the hot air in the drying area. The paper packaging bag needs to stay in the drying equipment for a long time, which can easily reduce the work efficiency of packaging bag processing. Therefore, we propose a drying device for gluing paper packaging bags. Utility Model Content
