Description

Technical Field

[0001] The utility model relates to the technical field of woven bag production, in particular to a palletizing gripper for woven bags. Background Technique

[0002] A woven bag is a bag made mainly of plastic through a weaving process. It has relatively high strength, can bear a certain weight and pressure, and has good durability, with good wear and tear resistance; in addition, the production cost of woven bags is relatively low, and the production process is relatively simple, so the price is relatively economical; woven bags have the physical characteristics of being very thin and light in texture.

[0003] When woven bags are mass-produced, they need to be transported in batches; Chinese Patent Publication No. CN211073651U discloses a woven bag gripper. The gripper includes a base, and gripper connecting rods are respectively arranged at both ends of the base. Multiple groups of gripper units are respectively arranged corresponding to the gripper connecting rods at both ends. The gripper unit includes a gripper base. One end of the gripper base is linked with a swing rod through a rotating shaft. A baffle is arranged inside the swing rod, and a plurality of L-shaped hooks are evenly arranged on the baffle. A cylinder seat is arranged on the gripper base, and the cylinder seat is hinged with a cylinder. The output shaft end of the cylinder is hinged with one end of a hinge plate through a pin shaft;

[0004] For the above-mentioned woven bag gripper, a cylinder is used to control the rotation and movement of multiple L-shaped hooks, so that the multiple L-shaped hooks cooperate to grab the stacked woven bags; however, the quality of woven bags is very light. During transportation, if the speed of the woven bags is too fast or there is an air flow blowing through the woven bags, the woven bags will be displaced, resulting in the disorder of the positions of the stacked woven bags and they will no longer be neat; the multiple L-shaped hooks of the above-mentioned woven bag gripper only serve to grab the woven bags, but cannot organize the untidy woven bags, so that the woven bags on the gripper are still in a disordered state. Under the squeezing force during the grabbing of the L-shaped hooks, the scattered woven bags are prone to be squeezed against each other, causing creases on the woven bags and affecting the quality of the woven bags.

Then the two fourth cylinders 414 respectively control the two pressing plates 416 to descend, so that the two pressing plates 416 press the woven bags between the two groups of folding rakes 413; then the belt 51 drives the entire palletizing grasping device 4 to move, and the woven bags move synchronously. When the woven bags move, the two pressing plates 416 can press the woven bags to prevent the woven bags from being scattered or falling due to too fast movement speed or the blowing of air flow.

[0049] After the two closing plates 410 tidy up the woven bags, the two third cylinders 47 respectively control the two sets of closing rakes 413 to rotate and approach each other, and while approaching each other, grip the woven bags on the lifting rakes 23. Then the two fourth cylinders 414 respectively control the two pressing plates 416 to descend, so that the two pressing plates 416 press the woven bags between the two sets of closing rakes 413. Then the belt 51 drives the entire palletizing gripping device 4 to move, and the woven bags move synchronously. When the woven bags move, the two pressing plates 416 can press the woven bags to prevent the woven bags from being scattered or falling due to too fast movement speed or the blowing of air flow.
