Description

Technical Field

[0001] The present application relates to the technical field of packaging box production and processing, and in particular to an automatic bonding device for combined packaging boxes. Background Art

[0002] With the rapid development of e-commerce, the demand for packaging boxes of various sizes, especially oversized ones, is increasing. Traditionally, the production and pattern printing of such packaging boxes usually rely on a single large-scale production equipment. However, when dealing with packaging boxes that are too large or have large-area pattern requirements, existing printing equipment is often unable to meet the demand due to size limitations, resulting in the need to purchase higher-specification machines, which not only increases the company's initial investment cost, but also reduces the daily use frequency and economy of the equipment.

[0003] Regarding the above-mentioned related technologies, there are several common solutions in the market, mainly including: one is to purchase special printing machines suitable for larger-sized packages, but this will significantly increase the company's fixed cost expenditure; the second is to decompose a single large package into two smaller parts, print them separately and then splice them, but this approach faces many challenges in actual operation; on the one hand, traditional splicing methods mostly rely on semi-automatic equipment to carry out gluing and pressing processes, and the work efficiency is relatively low; on the other hand, some small enterprises and workshops still even use manual assembly, which is not only labor-intensive, but also unstable product quality, which can easily lead to a decrease in the yield of finished products.

[0004] Whether using high-end and expensive professional printing machinery or simple manual assembly, there are obvious limitations and shortcomings. Although the former can achieve efficient mass production, it is a heavy economic burden for small and medium-sized enterprises; although the latter has a small initial investment, it is too backward in the modern industrial environment and difficult to adapt to the rapidly changing market demand.
