Problems solved by technology

When starting to sew again, a long starting thread will remain on the sewing material, because the sewing machine starts sewing fast, the remaining starting thread will be sewn into a bird's nest shape, affecting the aesthetics of the product, and usually requires manual trimming
[0003] In the prior art, a sewing machine bird's nest removing device and a method of use are recorded, which use a device for cutting the excessively long starting thread ends. Pull up the thread end and cooperate with the clamping plate to clamp the thread end. When the needle moves downward, the clamped thread end will contact with the blade set at the bottom of the wire groove, and then cut the thread end, avoiding the appearance of bird's nest , however, this technology can only be applied to single-needle sewing machines, while in industry, automatic control of double-needle sewing machines is more widely used, and double-needle sewing machines also have the bird's nest problem

Abstract

The invention discloses a two-needle sewing machine, which comprises a clamping component (2) capable of adjusting position according to a needle position so as to clamp a sewing thread end and a linehooking component (1) capable of adjusting position according to the needle position and matching with the clamping component (2) to clamp the sewing thread end. The two-needle sewing machine furthercomprises a line cutter (33) for cutting off the sewing thread end. The line hooking component and the clamping component in the two-needle sewing machine can adjust position according to the sewingmachine; the sewing thread end can be hooked and clamped at different needle positions, and then the sewing thread end is cut off through the line cutter, thus the sewing thread end of the two-needlesewing machine is sheared and shortened, and the appearance of the bird's nest is avoided.

Description

technical field [0001] The invention relates to the field of textile processing, in particular to a double-needle sewing machine. Background technique [0002] At present, in the continuous working process of the sewing machine, after a sewing job is completed, the upper thread is cut off as required, and then the next step of sewing is performed. After thread trimming, a longer starting thread is left to prevent the upper thread from falling off the sewing machine needle. When starting to sew again, a long starting thread will remain on the sewing material, because the sewing machine starts sewing fast, the remaining starting thread will be sewn into a bird's nest shape, affecting the aesthetics of the product, and usually requires manual trimming . [0003] In the prior art, a sewing machine bird's nest removing device and a method of use are recorded, which use a device for cutting the excessively long starting thread ends. Pull up the thread end and cooperate with the...
