Description

Technical Field

[0001] The utility model relates to the technical field of plastic ton bag sewing, in particular to a plastic ton bag sewing and hemming device. Background Art

[0002] Ton bag, also known as ton bag, container bag, space bag, is a flexible woven container with the advantages of moisture-proof, dust-proof, radiation-resistant, firm and safe, and has sufficient structural strength. As container bags are easy to load and unload and carry, the loading and unloading efficiency is significantly improved. They have developed rapidly in recent years. Ton bags are generally made of polyester fibers such as polypropylene and polyethylene. They are used to hold granular or powder products, which are convenient for transportation and easy to carry. They are currently very convenient packaging products for containerized transportation. They can be used for transportation and storage with forklifts and cranes. When sewing the edges of ton bags, a sewing machine is needed to sew the edges of the ton bags.

[0003] At present, in the process of hemming and mending the edges of plastic ton bags, the hemming strips are usually folded manually onto the edge of the plastic ton bag to be hemmed, and then the hemming strips are sewn on with a sewing machine. Since the fabric is prone to wrinkles after manual folding, and the hemming strips are difficult to remain flat and stable for a long time during the hemming process, it is easy to cause large deviations and unsightly appearance of the plastic ton bag after hemming. Therefore, we propose a hemming and mending device for plastic ton bags. Utility Model Content
