Description

Technical Field

[0001] This application relates to the field of sewing devices, and in particular, to a sewing machine with efficient feeding. 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 as to interweave or sew together one or more layers of sewing materials. Generally, a sewing machine consists of four parts: a machine head, a machine base, a transmission, and accessories.

[0003] The feeding of a sewing machine is generally carried out by manually moving the fabric, or some enterprises with high automation will be equipped with an automatic feeding device on the sewing machine for feeding. Although automatic feeding saves most of the labor, the two sides of the fabric may warp, resulting in incomplete sewing during the sewing process, or may affect the smoothness of sewing, and ultimately affect the sewing quality, which needs to be improved.

Each set of feeding mechanisms can feed the material at staggered times. The specific working conditions are as follows: First, the worker places the fabric on the feeding plate and presses both sides of the fabric with the presser foot of the fitting component. Then, the driving component drives the sliding plate on one side of the sewing head to move, so that the sliding plate is located below the sewing head, and the sewing position of the fabric on the feeding plate is directly below the sewing head. After that, the sewing head starts to work, and the feeding component feeds the material at the same time, causing the feeding plate to move, so that the fabric is sewn.
