Description

TECHNICAL FIELD

[0002] In a printing workshop, after the completion of printing (finished product), the printing needs to be packed or boxed. Some printing is packed and then boxed, and some is directly boxed. Under normal circumstances, manual work is required to load the printing into the box according to the order of the printing, and manual work is also required for the sub-assembly of the box. After the manual work of loading the box is completed, the box is transported to the labeling equipment and the packing equipment for labeling and packing. This method of loading the box involves more manual work, which is prone to errors or labeling errors, and the cost loss is large. The labor intensity of the workers is also large, and in a period of large business volume, the manual work needs to be increased to complete the task of loading the box, which is prone to cost loss such as missing loading and wrong loading.

[0003] In addition, according to the particularity of the product (printed product), each product and each specification requires that the size of the packaging paper box be different, so the cross-shaped paperboard that is easy to manufacture and has stronger adaptability is mostly used, and the traditional corrugated paperboard with high manufacturing cost and limited packaging, as well as the matching box pasting machine, are abandoned. Most of the paperboard box forming equipment still uses the box forming mechanism of the box pasting machine. For example, the invention patent with the application number 202510287537.9 discloses a paper box top cover packaging device and method, and the invention patent with the application number 2024116845919 discloses a corrugated paperboard box forming machine and method. The paper box is formed into a space inside the paper box to complete the covering action of the paper box, thereby completing the material packaging. The method is suitable for semi-finished paper boxes (the corrugated paperboard has been bonded, but is pulled into a box), and requires the size of the corrugated paperboard to be fixed. Therefore, the problems of rapid box forming and automatic box folding of the cross-shaped paperboard blank cannot be solved, and the problem of conveniently adjusting the size of the paper box according to the size of the material cannot be solved.
