[0002] The double needle sewing machine is a sewing machine used for sewing original parts and assembly sewing of components, which can greatly improve work efficiency and save operation time. The thread feed bracket of the double needle sewing machine is a device used to support and guide the sewing thread, which plays an important role in the sewing process of the double needle sewing machine.

[0003] The prior art discloses a thread feeding bracket for a turning double-needle machine with an application number of 202020292057.4, comprising a telescopic support rod, a placement plate fixed at the lower part of the telescopic support rod, a thread wheel fixing cone equidistantly distributed on the placement plate, a mounting plate welded on the top of the telescopic support rod, a battery slot provided on the mounting plate, and dry batteries installed in the battery slot, lamp beads equidistantly distributed on the mounting plate, and a threading rack equidistantly distributed and adapted to the position of the lamp beads welded at the bottom of the mounting plate, the threading rack comprising a U-shaped frame, a moving contact piece slidably mounted on the inner wall on both sides of the U-shaped frame, and a micro spring welded at the bottom of the moving contact piece. The utility model can adjust the distance between the mounting plate and the placement plate, is suitable for thread wheels of different heights, can send out an alarm through a buzzer to remind workers that the thread is broken after the thread is broken, and the lamp beads indicate to the workers which specific thread is broken, so that the workers can find the thread breakage phenomenon in time and improve the sewing efficiency.
