[0002] In the gift box packaging industry, lidded gift boxes are widely used for high-end product packaging due to their aesthetically pleasing structure and strong protective properties. The bonding paper, a crucial component of lidded gift boxes, directly impacts the overall appearance and structural strength of the gift box. Traditional bonding processes often rely on manual labor or semi-automatic equipment, resulting in low efficiency, uneven bonding, and poor consistency, making them unable to meet the dual demands of product quality and production efficiency for modern large-scale production.

[0003] There are some automated bonding devices on the market, but most of them can only complete bonding operations in a single direction. For example, they can only achieve the bonding of the connecting paper to the outer wall of the gift box, while the folding and pressing of the inner wall still requires manual assistance, resulting in a lack of consistency in the overall process and affecting production efficiency. In addition, during the bonding process, due to the lack of effective positioning and pressure control mechanisms, the connecting paper is prone to defects such as deviation, wrinkling, and weak adhesion, which affects the yield rate. In particular, in the process of folding and pressing the connecting paper from the outside of the gift box to the inside, traditional equipment often cannot achieve synchronous and adaptive adjustment, resulting in unstable bonding effect and even requiring secondary rework, further reducing production efficiency.
