Technical Field

[0001] This utility model relates to the field of packaging production technology, and in particular to a glue spraying device for a carton packaging machine. Background Technology

[0002] Paper box packaging refers to packaging containers made primarily of paper products through folding, gluing, and other methods. It boasts advantages such as lightweight, high plasticity, and environmental friendliness, while also possessing strong pressure resistance and moisture-proof properties. Suitable for packaging various products, paper box packaging is widely used in the commodity packaging field, including food, daily necessities, and electronic products. Due to its aesthetic appeal and practicality, it is often used for gift packaging, enhancing the perceived value of gifts. Paper box packaging comes in various shapes; for example, a strip box refers to a strip-shaped paper box. During paper box packaging production, the packaging machine needs to apply glue to facilitate subsequent adhesion and shaping of the paper box, thus requiring the use of a glue spraying device.

[0003] Traditional carton packaging machines often have exposed glue spraying heads. While these heads can perform glue spraying, the lack of protection makes them prone to accidental damage during the loading and unloading of cardboard boxes. Additionally, residual paper scraps from the boxes can easily fly up and adhere to the glue spraying head, causing blockages and affecting the normal operation of the glue spraying process.
