Description

Technical Field

[0001] The utility model relates to the technical field of gluing in paper box production, in particular to a paper box color printing and gluing device. Background Art

[0002] The carton is a common packaging material, mainly made of cardboard or paper, and processed by folding, gluing or die-cutting. During the carton production process, the cardboard usually needs to be glued.

[0003] A Chinese patent with announcement number CN219583625U discloses an automatic gluing device for carton production, wherein side fixing plates are provided on both sides of the base, and side guide plates are provided on the inner sides of the side fixing plates on the top of the base, and mounting holes are provided in the centers of the side fixing plates on both sides, and the conveyor belt is installed inside the mounting holes. An adjustment groove is provided in the middle section of the top of the base, and an adjustment threaded rod is installed inside the adjustment groove. When the utility model is in use, the carton is pushed to the top of the base, and the second drive motor is started to drive the adjustment threaded rod to rotate, so as to adjust the distance between the side guide plates on both sides, so as to adapt to the transmission function of cartons of different sizes. The conveyor belts on both sides can clamp the carton and move it backward. The whole process is more stable, no offset will occur, and it is more practical and efficient.

In addition, when gluing, it is easy to have uneven glue coating, thereby affecting the coating quality of the product. Therefore, a paper box color printing gluing device is proposed to address the above problems. Utility Model Content

After the cardboard is glued, it is continuously conveyed by the conveyor belt 41. When the glued cardboard passes through the bottom end of the roller 27, the roller 27 can evenly apply the glue on the cardboard, thereby achieving even gluing, improving the gluing effect, and improving the quality of product coating; in order to ensure the uniform gluing effect of the subsequent roller 27, the scraper 31 is provided to scrape and clean the residual glue on the roller 27, ensure the cleanliness of the surface of the roller 27, thereby ensuring the uniform gluing effect of the subsequent roller 27, and the scraped glue will fall onto the guide baffle 34 and flow into the collection trough 36 along the guide baffle 34, thereby realizing the collection of the glue.
