Description
technical field [0001] The invention relates to the technical field of equipment protection, in particular to a needle protection device for sewing machines. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material. The sewing machine can sew fabrics such as cotton, fiber crops, silk, wool, and artificial fibers, and products such as leather, plastics, and paper. And it derived art forms such as hand-push embroidery and computer embroidery. In industrial production, various problems often occur during the use of sewing machines, among which broken needle is a common problem. Broken needle is that the needle is broken due to unexpected resistance and obstacles. Contents of the invention [0003] The object of the present invention is to provide a needle protection device for sewing machines, which has the advantage of prote...
