Description

Technical Field

[0001] This utility model relates to the field of quilting machine technology, specifically to a fabric tensioning device for a quilting machine. Background Technology

[0002] A quilting machine is a textile machine used to sew linear patterns onto the surfaces of mattresses, bedspreads, quilts, and other similar items. Quilting machines used for quilt sewing can be divided into two categories based on the number of stitches and the variety of patterns they can create: straight quilting machines and computerized quilting machines. Straight quilting machines typically come in 7-needle, 9-needle, and 11-needle configurations; these machines can only sew straight lines. Computerized quilting machines, on the other hand, are single-needle designs and use a computer-controlled visual interface to move the machine and create patterns.

[0003] For example, during the processing of cotton quilts, due to their large volume and soft texture, they need to be clamped and tightened before sewing. The quilt is clamped by multiple clips on all four sides. With so many clips, manual operation is required for each clip individually, making the process cumbersome. Therefore, improving existing tensioning devices and designing a new type of fabric tensioning device for quilting machines to address these technical shortcomings and improve the overall practicality of the tensioning system is particularly important.
