Problems solved by technology

[0002] During the sewing process of clothes, the needle drives the suture thread into the product to be sewn. After the thread hook mechanism hooks the upper thread, the thread hook mechanism releases the upper thread. After the upper thread is released, the upper thread is collected by the thread take-up lever. Tight, interweaving with the bottom thread to form stitches to complete the sewing of the item. Since the movement track of the thread take-up lever is fixed, in the process of tightening the upper thread by the thread take-up lever, the tension force on the upper thread is different when the upper thread is at different positions. During the sewing process, the tension of the suture wi

Embodiment Construction

[0008] See figure 1 , an improved sewing machine thread take-up lever structure, which includes a sewing machine thread take-up lever body 1, a threading hole 2 is set on the sewing machine thread take-up lever body 1, the threading hole 2 is a long slot hole, and a transverse notch 3 is set on the long slot hole 2, and the line When running to the end of the long slot hole, the thread will stay in the transverse gap for a certain period of time to ensure the thread take-up during the sewing process and better ensure the thread amount matching the thread passing amount, so that the thread take-up lever can run to different positions The feeding amount of the upper thread and the pulling force of the upper thread are kept stable, so that the tension of the suture is more stable, and the stitches in the sewing of the clothes are more stable, which further ensures the sewing effect and quality of the clothes, and further avoids the upper thread the break,.

Abstract

The invention provides an improved sewing machine take-up lever structure. In the sewing process, when a take-up lever runs to different positions, the thread feeding amount of an upper thread and thepulling force of the upper thread are kept stable, therefore it is further guaranteed that stitches in the sewing process of clothes are stable, and the sewing effect and sewing quality of the clothes are better improved. The improved sewing machine take-up lever structure comprises a sewing machine take-up lever body, the sewing machine take-up lever body is provided with a threading hole whichis a long slotted hole, and the improved sewing machine take-up lever structure is characterized in that the long slotted hole is provided with a transverse notch.

Description

technical field [0001] The invention relates to the technical field of sewing equipment components, in particular to an improved structure of a thread take-up lever of a sewing machine. Background technique [0002] During the sewing process of clothes, the needle drives the suture thread into the product to be sewn. After the thread hook mechanism hooks the upper thread, the thread hook mechanism releases the upper thread. After the upper thread is released, the upper thread is collected by the thread take-up lever. Tight, interweaving with the bottom thread to form stitches to complete the sewing of the item. Since the movement track of the thread take-up lever is fixed, in the process of tightening the upper thread by the thread take-up lever, the tension force on the upper thread is different when the upper thread is at different positions. During the sewing process, the tension of the suture will change, causing the stitches in the sewing of the clothes to be unstable, ...
