Problems solved by technology

[0003] The sewing mechanism in the sewing machine generally includes mechanisms such as a presser foot and a needle plate. When an ordinary sewing machine is working, the fabric is placed on the needle plate, and the fabric is conveyed through the feed dog. It is enough to suture. In the existing actual production, in order to improve the efficiency of sewing, a suture template will be added to the needle plate during operation. The stitching positions are all on the same straight line, the stitches of the stitched fabrics are not beautiful, and the production efficiency is also low, which cannot meet the needs of the market

Abstract

The invention discloses a sewing mechanism. The sewing mechanism comprises a presser foot and a needle plate, wherein the presser foot is located above the needle plate which is provided with a plurality of installation holes; a positioning block is fixedly arranged below the presser foot; the positioning block is provided with a plurality of positioning holes; the needle plate is provided with a plurality of sewing needle holes; the positioning block is cylindrical; the sewing needle holes are three in number. According to the sewing mechanism, as the positioning block is additionally arranged below the presser foot of the sewing mechanism, the positioning block is provided with the positioning holes, and the needle plates is provided with the sewing needle holes corresponding to the positioning holes, when a sewing machine starts to work, sewing is conducted only through the positioning holes in the positioning block. Therefore, during operation, manual alignment is not needed, stitches of sewn fabric are beautiful, production efficiency is high, and market requirements are met.

Description

technical field [0001] The invention relates to a sewing mechanism, in particular to a sewing mechanism used on a sewing machine. 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. [0003] The sewing mechanism in the sewing machine generally includes mechanisms such as a presser foot and a needle plate. When an ordinary sewing machine is working, the fabric is placed on the needle plate, and the fabric is conveyed through the feed dog. It is enough to suture. In the existing actual production, in order to improve the efficiency of sewing, a suture template will be added to the needle plate during operation. The stitched positions are all on the same straight line, so th...
