Sewing machine broken thread quick threading device for intelligently manufacturing leather products

Abstract

The invention relates to the technical field of leather products, and discloses a sewing machine broken thread quick threading device for intelligently manufacturing leather products. The sewing machine broken thread quick threading device comprises a shell, a rotating block is movably connected into the shell, and the rotating block is connected with an automatic threading mechanism and an automatic lubricating oil spraying mechanism. After a sewing thread is broken in the operation process of a worker using a sewing machine, the worker presses a finger pressing block to contract towards themiddle, the contraction of the finger pressing block drives the rotating block to rotate, the rotation of the rotating block drives a clamping block to move leftwards in a clamping block groove, the clamping block is clamped in the clamping block groove due to the elastic force of a clamping block spring, at the moment, a thread residue is clamped, after the worker loosens the finger pressing block, the clamping block is extruded under the action of a fixed sliding groove rod, so that the clamping block resets from the clamping block groove and compresses the clamping block spring, a thread pulling clamping jaw is opened again to release the thread of the sewing machine, and the function of automatic threading after the thread of the sewing machine is broken is achieved.

Description

technical field [0001] The invention relates to the technical field of leather products, in particular to a fast threading device for sewing machines for intelligently manufacturing leather products. Background technique [0002] Leather products are frequently used fabrics in current clothing design. Leather not only has a certain flexibility, but also has a certain waterproof effect. Its biggest advantage lies in its heat preservation function. Therefore, many leather products are mostly jackets and purses. Products made of leather materials have a longer service life, so leather products are sold in the market more than ordinary cloth. [0003] However, when making leather products, it is often necessary to use a sewing machine to sew the surface to connect the materials. However, due to the large difference between the surface strength of the leather material and the cloth, there will be sewing lines when sewing due to high friction. The phenomenon of large fractures re...
