[0002] As a widely used commodity packaging solution, pasted paper boxes are widely used in the packaging and presentation of tools, gifts, clothing (such as shirts), shoes and other fields. Its sophisticated production process integrates the precise cutting, folding and composite bonding technology of paperboard.

[0003] The traditional production process includes several core steps: starting from pre-cutting of cardboard, applying adhesive at designated locations, folding and gluing the longitudinal edges, repeating the same process in the transverse direction, and finally ensuring the stability of the three-dimensional structure of the carton through careful longitudinal and transverse folding and firm bonding. Some high-quality carton boxes even have prefabricated support structures added inside to enhance the overall rigidity, and the outside is fixed with adhesive-coated cardboard.

[0004] Although the existing carton forming machines on the market focus on pressing the cardboard onto a pre-set support structure to build a complete carton shape, in the actual production chain, carton forming also includes a series of indispensable auxiliary process links, such as paper guide positioning, precise gluing and orderly conveying.
