Description

Technical Field

[0001] The utility model relates to a needle plate, in particular to a needle plate of an industrial sewing machine. Background Art

[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material, so that one or more layers of sewing material are interwoven or sewn together. Sewing machines can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, and have spawned art forms such as hand-push embroidery and computer embroidery. The most important thing is that the needle plate cooperates with the sewing machine's thimble to provide an effective pressure-bearing carrier for the fabric.

[0003] At present, the needle plate of a sewing machine is mainly a thin plate structure, with a needle hole adapted to the sewing machine thimble in the middle. As the part of the fabric to be sewn is placed on the top of the needle plate and the thimble vibrates at high frequency, the needle plate with a thin plate structure is easily compressed and deformed at the needle hole in the middle, which then causes the needle hole to have a funnel structure. At the same time, the existing needle plate can only adapt to the same model of sewing machine, and it cannot adapt once the position of the needle is offset. Utility Model Content
