Problems solved by technology

[0002] Press, the existing automatic thread trimming sewing machine will keep a section of needle thread on the needle (the length of the thread end from the needle hole is about 40mm) when the sewing is finished and the automatic thread trimming action is completed, so as to prevent the thread end from slipping out of the needle when sewing next time hole, causing the hassle of needing to rethread
However, this section of needle thread will be drawn into the bottom of the fabric by the needle and then pulled down by the rotary hook at the next sewing start, and will form a bunch of redundant thread ends under the first stitch

Abstract

The invention relates to a needle thread supplying device applied to a sewing machine; a power group for pushing a thread passing shaft group and driving a lifting plate to act is arranged on the needle thread supplying device; when the lifting plate enters for unfolding a needle thread clamp group, the thread amount between a support point and a thread hanging plate is the shortest and is also the smoothest; when the lifting plate exits the needle thread clamp group, the needle thread clamp group closely clamps suturing threads, the power group continuously pushes the thread passing shaft group for tensioning the suturing threads; the thread amount between the support point and the thread hanging plate is lengthened; and as the needle thread clamp group closely clamps the suturing threads, the suturing threads cannot obtain the thread amount between the support point and the thread hanging plate from the needle thread supplying device, and can only recycle the thread amount from the front end of the head of the suturing head; therefore, the length of a suturing needle thread is shortened, and the work on manually removing the length of extra thread heads is omitted.

Description

technical field [0001] The invention relates to a needle thread supply device for a sewing machine, in particular to a needle thread clamp set, a bobbin set, a dial and a power set, and the power set pushes and pulls the bobbin set, so that the bobbin set drives the dial. The plate stretches out or withdraws from the needle thread clip group, so that it has the effect of adjusting the amount of thread and reducing the length of redundant starting thread, and is suitable for various sewing machine models or similar structures. Background technique [0002] Press, the existing automatic thread trimming sewing machine will keep a section of needle thread on the needle (the length of the thread end from the needle hole is about 40mm) when the sewing is finished and the automatic thread trimming action is completed, so as to prevent the thread end from slipping out of the needle when sewing next time hole, causing the hassle of needing to rethread. However, this section of needl...
