Description

Technical Field

[0001] The utility model relates to the technical field of packaging box production, in particular to an automatic glue spraying machine for packaging box production. Background Art

[0002] As the name implies, packaging boxes are boxes used to package products. With the rapid development of modern industry and the continuous improvement of people's living standards, people's demand for packaging boxes will continue to increase. Most of the packaging boxes used on the market are paper packaging boxes, and the packaging box cardboard will be glued and assembled during production.

[0003] The existing gluing of packaging box cardboard is generally performed on the four sides of the packaging box cardboard. The gluing method can be performed by a single gluing nozzle through a preset path (the cardboard does not move during gluing), or firstly by two gluing nozzles to simultaneously glue the two width edges of the packaging box cardboard (the cardboard does not move during gluing), and then by two gluing nozzles to simultaneously glue the two length edges of the packaging box cardboard (the cardboard moves during gluing), so as to improve work efficiency. However, the applicant has found that most of the existing gluing machines can only glue packaging box cardboard of one size, and cannot be adjusted according to packaging box cardboards of different lengths and widths, and have low applicability.

[0004] Therefore, the applicant proposes an automatic glue-applying machine for packaging box production to solve the above problems. Utility Model Content
