[0002] Paper-plastic composite bags are a type of packaging material that combines paper and plastic film through a composite process. They have the toughness of paper and the barrier properties of plastic and are widely used in product packaging in the food, chemical, pharmaceutical and other industries. With the global emphasis on environmental protection, reducing the use of plastics has become an important issue. Paper-plastic composite bags are increasingly favored by the market due to their recyclability and ability to reduce plastic consumption.

[0003] Modern packaging has higher and higher functional requirements, such as barrier properties, freshness preservation, UV resistance, anti-static, etc. Paper-plastic composite bags can meet a variety of functional requirements by selecting different papers and plastic films, and adding functional coatings. The development of technologies such as flexographic printing and gravure printing has enabled paper-plastic composite bags to have good printing effects, which can meet the market's demand for packaging aesthetics and information communication.

[0004] The regulatory standards for food safety and packaging material safety are becoming increasingly stringent. The production of paper-plastic composite bags needs to comply with the regulatory requirements of relevant countries and regions, which places higher demands on the quality control and product safety of manufacturers. With the continuous advancement of technology and the continuous changes in market demand, the technology of paper-plastic composite bags will continue to develop and innovate.

[0029] like Figure 3 As shown, sleeves 7 are symmetrically arranged on both sides of the glue coating component 6, and the sleeves 7 are slidably arranged on the crossbeam of the bracket 4. A pressure pump 8 is also arranged on one side of the sleeve 7. The pressure pump 8 is connected to the glue storage barrel 11 and injects glue into the glue barrel 61. The sleeve 7 and the glue coating component 6 can adapt to different workpieces or operating positions, and the pressure pump 8 and the glue storage barrel 11 ensure that the glue can be evenly applied to the required position. The whole equipment is used in industrial occasions that require precise coating of adhesives, such as automobile manufacturing, electronic product assembly, printing and packaging industries, etc., to improve product quality and improve production efficiency.

[0030] like Figure 3 As shown, separation rollers 71 are also provided on both sides of the sleeve 7. The separation rollers 71 are used to assist the substrate to pass smoothly during the gluing process, press both sides of the substrate while gluing the substrate, and prevent the substrate from sticking to the glue bucket 61.

Then, the material is placed on the conveyor belt 3 of the machine tool 2, and the conveyor belt sends the material to the gluing area. In the gluing area, the gluing component 6 on the bracket 4 starts to work, and the glue in the glue barrel 61 squeezes the glue out of the glue layer 63 by pressure to evenly glue the material. The gluing holes 632 opened on the outer wall of the glue layer 63 help to evenly distribute the glue. A layer of divergent gaps 633 set in the middle of the glue layer 63 helps the glue to form a uniform coating on the material.
