Description

Technical Field

[0001] The utility model relates to the technical field of untwisting devices, in particular to an automatic untwisting device for twisted yarns. Background Art

[0002] Stainless steel sewing thread is a thread product made by twisting several thinner steel wires. The thread often gets tangled and entangled during use, which leads to serious thread breakage when used on a high-speed sewing machine. This is because the knotted stainless steel sewing thread cannot pass through the needle hole of the sewing machine, and the pulling of the sewing machine will cause the stainless steel sewing thread to break, so a detwisting device is needed.

[0003] The existing patent discloses an automatic untwisting device for twisting thread (publication number: CN219991812U), which can untwist the stainless steel wire sewing thread during use to ensure that the sewing thread will not break during the use of a high-speed sewing machine. However, during the untwisting process, the motor drives the synchronous wheel and the rotating tray to rotate. When the knotted or entangled sewing thread is untwisted, the motor cannot stop the rotating tray in time, and thus will continue to drive it to rotate, which easily causes the sewing thread to become knotted again, thereby reducing the untwisting efficiency. For this reason, the utility model proposes an automatic untwisting device for twisting thread. Utility Model Content
