Technical Field

[0001] The utility model relates to the technical field of plastic woven bag processing equipment, in particular to a locking device for processing plastic woven bags. Background Art

[0002] Woven bags, also known as snakeskin bags, are a type of plastic used for packaging. Their raw materials are generally polyethylene, polypropylene and other chemical plastic raw materials. Woven bags have a wide range of uses, mainly used for packaging and packaging of various items, and are widely used in industry. During the production process of woven bags, the cut of the woven bags needs to be locked.

[0003] The existing edge locking device for processing plastic woven bags is used to manually pull the woven bag to move it through the edge locking machine head, so as to achieve edge locking at the cut of the plastic woven bag. During the edge locking process, the manual traction is close to the edge locking machine head, which not only has certain safety hazards, but also the uncertain traction rate will cause the density of the edge locking line to be inconsistent, affecting its edge locking effect, resulting in low functionality of the device. Therefore, there is an urgent need for a edge locking device for processing plastic woven bags to solve the above problems. Utility Model Content
