Abstract
The invention discloses a novel automatic thread slacking device of a sewing machine. The device comprises a thread clamping plate, a first thread clamping device, a tensioning coil, a second thread clamping device and a third thread clamping device are arranged on the thread clamping plate separately, a first thread clamping device thimble is arranged on the portion, of the back face of the of the thread clamping plate, of the first thread clamping device, and a second thread clamping device thimble is arranged on the portion, of the back face of the of the thread clamping plate, of the second thread clamping device. The novel automatic thread slacking device is characterized in that a lever plate is fixed to the back face of the thread clamping plate through a fixing hinge pin, the end,of the orthographic projection of the first thread clamping device thimble and the orthographic projection of the second thread clamping device thimble, of the lever plate is tilted, and a retractablemechanism for driving the lever plate is arranged at the other end of the lever plate. According to the novel automatic thread slacking device of the sewing machine, by using a lever principle, a pneumatic retractable rod is adopted for driving all the thread clamping device thimbles, the device is quick and efficient to use, manual adjustment is not needed, the labor and time are effectively saved, and the production efficiency is improved.
