Description

Technical Field

[0001] The utility model relates to the technical field of carton palletizing, in particular to an automatic palletizing mechanism for packaging cartons. Background Art

[0002] Cartons are the most widely used packaging products. They come in a variety of sizes and models, including corrugated and single-layer cardboard boxes. During the carton processing process, the finished cartons need to be palletized for easy unified transportation or storage.

[0003] In this regard, the Chinese utility model patent with authorization announcement number CN215515684U discloses an automatic receiving and stacking device for printed cartons, including a placement table and a bottom plate. The top inner wall of the placement table is provided with a slide groove. A limit plate, a first motor, and two baffles are fixedly installed on the upper surface of the placement table. A first screw is rotatably installed on the left side of the limit plate. A movable plate is threadedly connected to the outer side of the first screw. A sliding rod is fixedly installed between the limit plate and the baffle. The movable plate is slidably sleeved on the outer side of the two sliding rods. A vertical rod is fixedly installed on the lower surface of the movable plate. A push plate is fixedly installed on the left side of the vertical rod. The left end of the first screw is fixedly connected to the output shaft end of the first motor. By providing a second motor, a second screw, a rectangular plate, a first movable rod, a second movable rod, a stacking plate, and a load-bearing plate, the utility model solves the problem that the traditional stacking method is not only inefficient but also wastes a lot of manpower.

[0004] During use, the automatic palletizing device for packaging cartons automatically stacks cartons into stacks by moving the stacking plate downward. After stacking is completed, a robot or other device needs to fork into the bottom of the stacking plate and fork the stacking plate from above the load-bearing plate. If the stacking work is to be continued, another stacking plate needs to be manually prepared and placed on the load-bearing plate for another stacking work, which reduces work efficiency.
