Embodiment Construction

[0015] As shown in the figure, two sewing needles 2 fixed on the needle bar 1 of the sewing machine 4 are distributed in parallel, and the needle bar 1 moves up and down by manpower or motor through a series of gears and cams. Shuttle hook and bobbin assembly 3 are arranged at the bottom of sewing machine 4, and the quantity of shuttle hook and bobbin assembly 3 in sewing machine 4 is 1; Thread; driven by the mechanical mechanism, it rotates synchronously with the movement of the needle bar 1; when sewing, two parallel sutures will be formed on one side of the fabric, and a 2-in-1 chain of sutures will be formed on the other side of the fabric suture.

[0016] When sewing, the sewing needle of the sewing machine partially passes through the fabric, and two needles pass through the fabric at the same time to pull out two loops. A shuttle hook and bobbin assembly catches the loop before the needle is pulled out, it moves synchronously with the needle, once the needle is pulled ...

Abstract

The invention provides a double-needle single-shuttle type sewing machine. The double-needle single-shuttle type sewing machine can produce the unique effect of two-in-one chained sewing, has a reinforcing effect and can improve the abrasion-resisting performance of fabric surfaces. The double-needle single-shuttle type sewing machine is characterized in that two sewing needles fixed to a needle rod in the sewing machine are distributed in parallel, and the needle rod is dragged manually or by a motor through a series of gears or cams to perform vertical motion; a swing shuttle hook and a bobbin assembly are arranged at the lower portion of the sewing machine, and a bobbin is located at the center of a swing shuttle and rotates under the drive of a mechanical mechanism to perform synchronous motion with the needle rod. During sewing, two mutually-parallel sewing lines are formed on one surface of a fabric, and the two-in-one chained sewing of one sewing line is formed on the other surface of the fabric.

Description

technical field [0001] The present invention relates to a sewing machine. Background technique [0002] Sewing machines are well-known to everyone. It saves us from heavy manual sewing labor and greatly improves the efficiency of sewing labor. [0003] With the development of society, people's requirements for textiles are also constantly improving. The simplest loop stitching of traditional sewing machines, that is, chain stitching, is becoming more and more difficult to meet the needs, and the simple chain stitching is not particularly strong. If one end of the thread is loose Open, the defect that the entire sewing may come loose. In order to sew beautiful and durable chain stitches, it is necessary to change the structure of the sewing machine. Contents of the invention [0004] In view of the above situation, the present invention provides a double-needle single-shuttle sewing machine, which can produce the unique effect of 2-in-1 chain stitching, and has a reinforc...
