Description

Technical Field

[0001] The utility model relates to the technical field of case packing machines, in particular to a double-column lifting and grabbing mechanism. Background Art

[0002] At present, the cartoning machines used by paper product manufacturers on the market are all single-station cartoning machines. After the paper products are packaged, they are transported to the product sorting station by the product feed conveyor belt of the cartoning machine. The cartons are transported to the waiting cartoning station through the carton conveyor belt of the cartoning machine. The cartons are fixed by the blocking and positioning mechanisms. Then the grabbing mechanism above the sorting station grabs the neatly sorted products and lifts them vertically, and moves them horizontally to the top of the fixed carton. At this time, the box supporting mechanism opens the upper fold of the carton, and the grabbing mechanism sends the product to the bottom of the carton and releases it. The product then falls into the carton. The grabbing mechanism is lifted vertically, and after it is higher than the height of the box supporting mechanism, it moves horizontally to the waiting cartoning station, and continues the next step of cyclic grabbing, vertical lifting, translation, and box dropping to complete the cartoning action.

[0003] To sum up, the existing single-station cartoning machine can only pack one box at a time. For the paper industry with fast beat and high production efficiency, the production efficiency cannot meet the corresponding production needs. For this reason, we propose a double-column lifting and grasping mechanism. Utility Model Content
