[0002] Paper box is a widely used green packaging container. It is not only widely used in the packaging of medicines, food, cigarettes and handicrafts, but also in soft drinks, detergents, cultural and educational supplies, and small hardware products. When processing paper boxes, it is necessary to splice the processed cardboard through the production line, so the paper box board needs to be glued through a laminating machine.

[0003] The utility model with patent number 202220718733.9 provides a carton gluing production line. The utility model makes the gluing effect of the device relatively stable through the structural design of the gluing component, and can adjust the number and position of the gluing heads according to the use requirements. The structure is relatively simple, which improves the operability and applicability of the device; through the structural design of the heating box group, the device can heat and keep the glue liquid warm, so that the glue liquid delivery is relatively stable, avoiding the inconvenience of delivery caused by the glue liquid delivery pipeline being too long and the glue liquid cooling and becoming viscous; however, when feeding paper, the existing gluing machine requires the staff to manually place the folded cardboard of the carton at the feeding port of the equipment and stack them neatly to ensure that the cardboard can enter the equipment normally for processing, which increases people's labor intensity, and the cardboard is also prone to warping and offset during transportation, thereby affecting the subsequent gluing effect and bringing inconvenience to subsequent work.
