Description

Technical Field

[0001] The utility model specifically relates to the technical field of automatic stacking, in particular to a mechanism for automatically stacking cartons after they are cut. Background Art

[0002] Automatic stacking of cartons is an important technology in modern logistics and production packaging. After the cartons are cut, they need to be stacked and placed. Automatic stacking equipment can ensure the neatness and stability of the carton stacking. Through precise positioning and stacking operations, the alignment error between cartons can be controlled within millimeters, reducing the risk of carton damage and cargo collapse due to uneven stacking.

[0003] At present, traditional stacking mechanisms require manual participation to achieve the stacking effect. However, especially in large-scale production and logistics distribution centers, manual long-term cardboard stacking work is prone to fatigue and inefficiency. Automatic stacking equipment can complete the task without a large amount of manpower, reducing labor intensity. It also helps to reduce labor costs while ensuring stacking efficiency and quality.

[0004] After searching, Chinese patent publication number CN202122209073.X discloses a multi-angle paper box automatic stacking mechanism; including a conveyor belt, a base is provided at the lower end of the rear part of the conveyor belt, multiple columns are provided on both sides of the upper end of the base, and a lifting seat is installed between the multiple columns on both sides, and multiple support rods are installed on the inner end walls of the two lifting seats, and each support rod is provided with a gear rail on the bottom end wall, and a support seat is provided on the outer side of the lower end of the two lifting seats, and a rotating shaft is provided in the lifting seat, and bearings are installed at both ends of the rotating shaft, and gears are provided on the inner sides of the two bearings, and fixed seats are provided on the inner sides of the two gears; the paper boxes are stacked and unloaded above the conveyor belt preferentially through the left support rod;

[0005] When stacking cartons, the stacking structure in the above-mentioned patent transfers the cartons to two supporting rods through the first guide belt, and realizes the automatic stacking effect by the lowering of the supporting rods. At that time, the structure in the above-mentioned patent cannot effectively guarantee the quality of the stacking of cartons during stacking, and may cause a large deviation between two adjacent cartons, which will cause the stacked cartons to tilt. When unloading, the cartons on the supporting rods are translated to the right through the supporting rods. When the supporting rods are retracted, the height of the stacked cartons may cause shaking or even tipping. Therefore, the automatic stacking structure in the above-mentioned patent still has certain technical defects. Utility Model Content

[0006] The purpose of the present utility model is to provide an automatic stacking mechanism for cartons after slitting.
