Description

Technical Field

[0001] This utility model relates to the field of duvet cover sewing technology, specifically a high-efficiency sewing device for duvet cover production. Background Technology

[0002] A duvet cover, also known as a quilt cover, is placed over a quilt to prevent it from getting dirty and to facilitate washing. It belongs to the category of bedding products. In the current technology, duvet covers are made by sewing the edges of two pieces of fabric together with a sewing machine, leaving an opening in the fabric to form a pocket structure, and then attaching several straps for fixing or sealing it with a zipper.

[0003] Chinese patent CN219972639U discloses a quilt cover sewing device. This patent discloses a technical solution to reduce manual labor and improve work efficiency. It solves the problem that when sewing quilts with existing sewing machines, manual flattening and sewing are required. Only one side can be sewn at a time. Moreover, during the sewing process, the quilt cover needs to be manually pulled to ensure that the sewing position is flat and the sewing position can be changed at any time to form a complete edge. This results in a large amount of manual labor and low work efficiency for the operator.

[0004] When in use, the device uses two electric sewing machines to sew the duvet cover on both sides, which speeds up the sewing process. However, when the duvet cover is placed on the left side of the sewing platform, it still requires the operator to pull it and sew a certain distance before it can be wound by the winding roller. The conveying effect is poor, which reduces the effectiveness of use. Therefore, a high-efficiency sewing device for duvet cover production is proposed to solve the above problems.
