Description

Technical Field

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

[0002] Ton bag is a special packaging bag product, also known as ton bag, which is a flexible transport packaging container with the advantages of moisture-proof, dust-proof, firm and safe. It is generally made of textile materials.

[0003] Ton bags are mainly composed of the main body, slings, reinforcement ribs, lining and loading and unloading ports. The slings of ton bags are mainly used to lift the ton bags carrying items, that is, the strength of the sling structure also determines the overall load-bearing strength of the ton bag. In each processing link of the ton bag, the slings are first sewn separately and then sewn together with the bag body.

[0004] During the individual sewing process, the slings are folded and sewn into the ear structure, especially the connecting ear in the middle. The two ends of the cut cloth strips need to be folded and sewn into an "8"-like ear structure. However, the folding process requires workers to fold it manually, which increases the risk of contact between the workers' hands and the sewing needle. Long working hours will also reduce work efficiency. Therefore, we propose a folding and sewing device for ton bag slings. Utility Model Content
