Description

Technical Field

[0001] This utility model relates to the field of garment processing equipment technology, specifically to a hemming device for sewing kangaroo bags. Background Technology

[0002] Hoodies are one of the most popular clothing styles in autumn, with various styles of crew neck hoodies, hooded hoodies, zip-up hoodies, and hoodie dresses being particularly popular among young people. In conventional clothing designs, pockets are mostly located on the sides, making it difficult to notice if something is lost. However, hoodie pockets are located in the front, greatly enhancing their anti-theft function. Whether it's a wallet or a phone, it's relatively safe to put it in the front pocket of a hoodie. Because the large front pocket on a hoodie is similar to a kangaroo pocket, it is also called a kangaroo pocket in the industry. Chinese patent document CN 111826820B discloses a kangaroo pocket sewing device, including a worktable assembly and sewing assembly, a folding assembly, a folding drive device, a pocket-shaped plate assembly, a pocket-shaped plate drive device, a pressing frame device, and a pressing frame drive device. The folding assembly and the pocket-shaped plate assembly cooperate to fold the pocket fabric. The folding drive device drives the folding assembly to move up and down, and the pocket-shaped plate drive device drives the pocket-shaped plate assembly to move back and forth. The pressing frame device is used to feed the folded pocket fabric and the body fabric to the sewing assembly for sewing. The pressing frame drive device drives the pressing frame device to move up, down, forward, backward, left, and right. The folding assembly includes a folding mounting base, a pocket upper pressing mold, a pressing mold mounting frame, and folding devices. The folding mounting base is a frame shape corresponding to the shape of the pocket fabric to be sewn. The pocket upper pressing mold is a plate shape with the same shape as the pocket fabric to be sewn, and is fixed to the folding mounting base from the rear by the pressing mold mounting frame, located inside the lower part of the folding mounting base. There are 3 folding devices, and the folding widths of the folding devices correspond to the corresponding side lengths of the pocket to be folded. Each of the 3 folding devices includes a vertical folding knife, a horizontal folding knife, and a folding knife drive cylinder. The vertical folding knife is used to fold the edge of the pocket fabric to be folded downwards, and the folding knife drive cylinder drives the horizontal folding knife to fold the fabric folded by the vertical folding knife inwards. The positions of the 3 folding devices correspond to the parts of the pocket to be folded. Because kangaroo pouches for sweatshirts come in various sizes, the entire hemming device needs to be replaced when processing kangaroo pouches of different sizes. This results in a high investment cost, time-consuming replacement, and low efficiency. Utility Model Content
