Description

Technical Field

[0001] The utility model relates to the technical field of folding and gluing packaging paper boxes, and more particularly to a folding and gluing device for producing packaging paper boxes. Background Art

[0002] In the current field of packaging carton production, the folding and gluing device is one of the key equipment in the carton forming process. The main function of this device is to apply glue to the folded edge of the carton to achieve bonding. However, the existing folding and gluing device has a common problem in the gluing process, that is, the sealing performance of the discharge pipe is insufficient. As a result, during gluing, the glue easily leaks out from the gap between the discharge pipe and the carton, which not only causes material waste, but also may pollute the equipment and working environment, reducing production efficiency and equipment reliability.

[0003] Specifically, when the existing folding and gluing device is in operation, the discharge pipe is responsible for evenly applying glue to the folding line of the paper box. However, due to design defects, the joint between the discharge pipe and the paper box is often not completely sealed, resulting in glue leakage during the high-pressure spraying process. This leakage not only affects the quality of the paper box and increases the cost of cleaning and maintenance, but also poses a potential threat to the health of the operator. In addition, glue leakage may also cause equipment failure, further affecting the stable operation of the production line. Utility Model Content

[0030] In this embodiment, when gluing the carton, the movement of the glue barrel 1 can drive the top head 15 to come into contact with the side wall of the carton, and then the top head 15 under pressure will expand and contract upward, and then release the seal between the sealing disk 4 and the sealing groove 7, and then the glue flows out to the carton through the annular groove 8, thereby completing the gluing process. When the amount of glue needs to be adjusted, the hexagonal rod 10 can be driven to rotate by rotating the top head 15.
