Abstract
The invention provides an improved structure of a take-up lever of a sewing machine, which is characterized in that a transverse notch is arranged on a long slotted hole.
Description
Technical Field
The invention 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 clothes, a machine needle drives a suture to be pricked into a product to be sewn, a hook mechanism hooks an upper thread, the hook mechanism releases the upper thread, the upper thread is tightened through a take-up lever after the upper thread is released, the upper thread is interwoven with a bottom thread to form a stitch, the sewing of the article is finished, the movement track of the take-up lever is fixed, the tension of the upper thread on the upper thread is different when the take-up lever tightens the upper thread at different positions in the sewing process, the tension of the suture can be changed in the sewing process, the sewing central line of the clothes is unstable, the sewing effect and the sewing quality of the clothes are influenced, an applicant invents a take-up lever structure of the sewing machine, the sewing central line of the clothes is effectively ensured to be stable, the sewing effect and the sewing quality of the clothes are better ensured, in the invention, the thread can instantly slide down to the bottom of a long slotted hole from the top end of the take-up lever due to the tension of the thread when the, allowing the suture to relax more quickly and thereby affecting the suture stitches.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides an improved thread take-up lever structure of a sewing machine, in the sewing process, 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 runs to different positions, so that the stability of stitches in the sewing of clothes is further ensured, and the sewing effect and the sewing quality of the clothes are improved.
The technical scheme is as follows: an improved thread take-up lever structure of a sewing machine is characterized in that a transverse notch is arranged on a slotted hole.
It is further characterized in that: the threading hole is an arc-shaped hole; the connection part of the long slotted hole and the transverse notch is an arc transition section.
By adopting the scheme, the transverse notch is formed in the long slotted hole, when the thread runs to the end part of the long slotted hole, the thread stays in the transverse notch for a certain time, the take-up in the sewing process is ensured, the thread quantity matched with the thread passing quantity is better ensured, and the thread feeding quantity of the upper thread and the tension of the upper thread are kept stable when the take-up lever runs to different positions in the thread hooking process of the thread hooking mechanism, so that the tension of the thread is more stable, the stitches in the sewing of the clothes are more stable, the sewing effect and the sewing quality of the clothes are further ensured, and the breakage of the upper thread is further avoided.
Drawings
FIG. 1 is a schematic view showing the structure of the improved thread take-up lever of the sewing machine according to the present invention.
Detailed Description
An improved thread take-up lever structure of a sewing machine is shown in figure 1, and comprises a thread take-up lever body 1 of the sewing machine, wherein a threading hole 2 is arranged on the thread take-up lever body 1 of the sewing machine, the threading hole 2 is a long slotted hole, a transverse notch 3 is arranged on the long slotted hole 2, when the thread runs to the end part of the long slotted hole, the thread stays in the transverse notch for a certain time to ensure the take-up in the sewing process, and better ensure the thread quantity matched with the thread passing quantity, so that the thread feeding quantity and the pulling force of the upper thread are kept stable when the thread take-up lever runs to different positions, the tension of the thread is more stable, the stitches in the sewing of the clothes are more stable, the sewing effect and the sewing quality of the clothes are further ensured, and the breakage of the upper thread is further.
The threading holes 2 are preferably arc-shaped slotted holes. So that the running of the suture in the threading hole is smoother.
The joint of the long slotted hole 2 and the transverse notch 3 is an arc transition section 4, so that the running resistance of the suture is reduced, the thread breakage is prevented, and the suture runs more smoothly.
The thread hooking mechanism generally comprises a rotary shuttle and a shuttle hook.
The stay time of the suture is controlled according to the length of the transverse gap, so that the synchronization of the thread hooking mechanism and the take-up and paying-off of the thread take-up lever is ensured.
The present invention and its embodiments have been described in detail, without limitation, and the accompanying drawings are only one embodiment of the invention, and the actual structure is not limited thereto, so long as those skilled in the art can design the structure and the embodiments similar to the above technical solution without departing from the spirit of the invention.
