Description

Improved thread take-up lever structure of sewing machine

Technical Field

The utility model relates to the technical field of sewing equipment parts, in particular to an improved thread take-up lever structure of a sewing machine.

Background

In the sewing process of the clothing, the machine needle drives the suture to be pricked into the product to be sewn, after the thread hooking mechanism hooks the upper thread, the thread hooking mechanism releases the upper thread, after the upper thread is released, the upper thread is tightened through the thread taking-up lever, and the upper thread and the bottom thread are interwoven to form a stitch, so that the sewing of the article is completed.

For example, the improved thread take-up lever structure of the sewing machine of the authorized bulletin number CN216040159U ensures that the thread feeding amount of the upper thread and the pulling force of the upper thread are kept stable when the thread take-up lever moves to different positions in the thread hooking process of the thread hooking mechanism, so that the tension of the thread is more stable, the stitch of the sewing thread of the clothes is more stable, the sewing effect and the sewing quality of the clothes are further ensured, and meanwhile, the breakage of the upper thread is further avoided.

However, the improved thread take-up lever structure of the sewing machine has some problems when in use, for example, the improved thread take-up lever structure of the sewing machine only designs a thread feeding structure of the thread take-up lever of the sewing machine, however, in the actual work of the sewing machine, the shape trend of a notch at the end part of a long groove is gradually narrowed, so when the thread of the sewing machine runs at the notch, friction contact is frequently generated between the thread and two sides of the notch, the long notch is rubbed by the thread of the sewing machine for a longer time, the subsequent running thread can slide on the smooth position of the notch, the thread moving track sent out after passing through the notch of the thread take-up lever of the sewing machine starts to shake, and finally the thread take-up lever of the sewing machine influences the sewing effect of the whole sewing machine.

Meanwhile, the current improved thread take-up lever of the sewing machine still exists, because the sewing machine has strict time requirements on the motion coordination of the thread take-up lever, the needle and the shuttle, especially on the thread take-up lever, the action coordination of the thread take-up lever and each mechanism of the sewing machine is required to be quite accurate and coordinated, otherwise faults such as 'jumping' and 'breaking' can be caused, however, the length of the thread take-up lever is always fixed, and when facing different thread types and sewing machine models, the length of the thread take-up lever of the sewing machine can not be adjusted, so that the thread take-up lever can not adapt to more sewing conditions, and the normal work of the sewing machine is finally influenced.
