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.

Description

technical field [0001] The invention belongs to the field of sewing machines, in particular to a novel automatic thread releaser for sewing machines. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material. A general sewing machine consists of four parts: machine head, machine base, transmission and accessories. [0003] During the use of the sewing machine, it is necessary to lift the presser foot to change the fabric or shift; in order to avoid the sewing thread being pulled and broken during the process of lifting the presser foot, it is usually used to release the thread release device at the same time during the process of lifting the presser foot. Existing sewing machine thread release device structure such as figure 1 shown. [0004] figure 1 It is a schematic diagram of the three-dimensional structure of the exist...
