Description

Technical Field

[0001] The utility model relates to the technical field of carton manufacturing equipment, in particular to a glue discharging device for carton manufacturing. Background Technique

[0002] With the changes in transportation methods and sales methods, the styles of cartons and paper boxes are becoming increasingly diverse. Almost every new type of non-standard carton is accompanied by a set of automated equipment. Moreover, the novel-shaped paper box itself has become a means of product promotion. Currently, during the production of cartons, it is usually necessary to apply glue to enhance the firmness. At present, the existing glue discharging devices have relatively simple structures. When applying glue to cartons, they cannot achieve the effect of synchronous glue discharging, and there is deviation in glue discharging, resulting in inconsistent quality of carton manufacturing products. At the same time, when the glue discharging equipment is not in use, due to gravity, there will be some small drops of glue dripping from the glue outlet. These glues in contact with air are prone to oxidation and thus solidify at the glue outlet, resulting in the need to scrape off waste glue every time it is used and unable to achieve the effect of sealing and protection. Therefore, we need to propose a glue discharging device for carton manufacturing.

[0003] After retrieval, the publication number CN217671405U discloses a glue discharging device for carton manufacturing. Glue is injected into the storage cylinder in the novel. The motor is started to drive two rotating gears to rotate. The rotating gears drive, and at the same time, the lifting rod drives the piston plate to squeeze the glue in the storage cylinder out. And through the extrusion of the glue, the piston block moves, and the piston block squeezes the supporting spring to be compressed, so that the glue is discharged from the discharge port at the bottom of the discharge pipe. When the glue discharging is completed, the motor moves in the reverse direction, and the piston plate moves slightly upward to facilitate the supporting spring to push the piston block to seal the discharge pipe, solving the above problems. However, there are still deficiencies: at lower temperatures, the glue is easy to solidify, difficult to use, and more likely to block the glue outlet. It is necessary for the staff to heat the glue first before adding it to the device, and there is still a solidification situation during the use process. And when applying glue to cartons, it cannot adapt to different carton sizes. Therefore, it is urgent to design a glue discharging device for carton manufacturing that can prevent the glue from solidifying and can adjust the distance between the glue outlets.
