[0002] Paper-plastic composite bags refer to packaging bags made of a paper-plastic composite base fabric formed by laminating kraft paper and plastic woven bags through an intermediate layer coating. When laminating the packaging film with a heat-resistant film, an adhesive roller is used to apply glue from the glue tank to the surface of the packaging film. Existing technology publication number CN220160406U discloses an adhesive application device for paper-plastic composite bag production, including an adhesive application box and an adhesive application assembly. One side of the adhesive application box is movably installed with one side of the adhesive application assembly. The adhesive application box includes a box body, one side of which is movably installed with one side of the adhesive application assembly. Passing slots are provided on both sides of the box body, and a guide plate is fixedly installed on one side of the box body, on the surface of the passing slot. However, the glue can solidify over time, and the inner wall of the device cannot be automatically cleaned after use. Manual cleaning is troublesome and time-consuming.
