Description

Technical Field

[0001] The utility model relates to the technical field of cardboard processing, in particular to a high-precision cardboard gluing device. Background Art

[0002] During the production process, packaging products such as paper boxes and cartons need to go through printing, slotting, die-cutting, gluing and other processes. Among them, the paperboard needs to be glued after slotting. During the gluing process, the edge of the paperboard needs to be glued, and then folded to form a box body or a box body. Traditionally, the gluing operation on the edge of the paperboard is mostly manual work, which is inefficient and not suitable for today's streamlined procedural operations. Nowadays, the paperboard is placed on a conveyor belt and displaced at a uniform speed, and then the glue is continuously extruded on the edges of both sides of the paperboard with a uniformly extruded hose to complete the rapid gluing operation. Compared with manual gluing, it has the advantages of high efficiency and sustainability. However, the paperboard is transported on the conveyor belt without a positioning mechanism to limit the displacement of the paperboard, and it is impossible to ensure that the edge of the paperboard is in stable contact with the gluing position during the movement. It is easy to cause the edge of the paperboard to warp or the left and right sides to shift. These will cause uneven distribution of glue on the edge, affecting the bonding quality. In addition, after the glue is extruded, a water line will be formed on the edge of the paperboard, which cannot fully cover the edge of the paperboard, thereby reducing the bonding surface, which also affects the bonding quality.
