Problems solved by technology

Due to the development of the garment industry, it is necessary to sew three parallel and equidistant stitches. At present, it is only possible to sew two parallel stitches with a double-needle lockstitch machine, and then use a single-needle lockstitch machine to sew the third stitch. That is, it needs two processes to complete, and the stitches are not beautiful

Embodiment Construction

[0012] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment, see Figure 1-5 :

[0013] like figure 1 As shown, after the movement is input to the lower shaft 1, the right large helical gear 4 and the left large helical gear 7 installed on the lower shaft 1 mesh with the right small helical gear 21 and the left small helical gear 20 respectively, which drives the right hook 2 and rotation of hook 3 (eg image 3 shown), the synchronous pulley 10 installed on the lower shaft 1 and the synchronous pulley 12 installed on the intermediate hook shaft 13 are connected through the synchronous belt 9, so that the movement of the lower shaft 1 can be synchronously transmitted to the intermediate hook shaft 13 , and in order to avoid assembly interference, the intermediate hook shaft 13 and the lower shaft 1 are not on the same level (such as figure 2 shown), the tension wheel 11 installed on the tension wheel frame ...

Abstract

The invention belongs to sewing machine technology, and provides a sewing machine that can complete three parallel lock stitch in one step instead of two in prior art. A left-handed shuttle and right-handed shuttle are driven to rotate by the engagement of two large helical gears and a small helical gear installed on a lower shaft; a synchronous pulley installed on the lower shaft and a synchronous pulley installed on an intermediate shuttle shaft are connected through a synchronous belt; the rotation of the lower shaft is transmitted to a middle large helical gear; a middle is driven to rotate by the engagement of the large and the small helical gears; when three needles move downward, three shuttles hook at the same time to form three-needle lock stitch, wherein, the third needle and the two needles form an isosceles triangle, and the third shuttle and the two shuttles form an isosceles triangle. The advantages of the three-needle lock stitch sewing machine are that the sewing efficiency is high; three parallel equidistant stitches can be made by one step; and the stitch seam is beautiful.

Description

technical field [0001] The invention belongs to the sewing machine technology, and designs a lockstitch sewing machine capable of completing three parallel lock stitches that can be completed in one step before requiring two processes. Background technique [0002] The structure of ordinary lockstitch sewing machine is single-needle or double-needle, which can sew one or two lock stitches at a time. Due to the development of the garment industry, it is necessary to sew three parallel and equidistant stitches. At present, it is only possible to sew two parallel stitches with a double-needle lockstitch machine, and then use a single-needle lockstitch machine to sew the third stitch. Promptly need two procedures to be able to finish, and thread trace is also not attractive in appearance. Contents of the invention [0003] The purpose of the present invention is to provide a three-needle lockstitch lockstitch sewing machine with high sewing efficiency, which can sew three par...
