Problems solved by technology

[0003] The existing thread take-up mechanism does not have the function of arranging the weaving thread in the process of leading the thread. The weaving thread is easy to be entangled and knotted, and it is difficult to clean the weaving thread, so that there are many flocs around the weaving thread, especially For some special weaving threads, if the weaving thread is introduced into the thread take-up mechanism without being tightened, it is easy to cause the floc around the thread to be separated from the thread body due to actions such as thread picking, threading, and piercing, resulting in The problem of thread breakage

Abstract

The invention discloses a thread take-up mechanism of an industrial sewing machine, relates to the technical field of the thread take-up mechanism of a sewing machine, specifically a base, a four-bar linkage mechanism, a thread take-up device, a thread management device and an adjustment device. A linkage mechanism, a fourth connecting arm is connected to the upper side of the four-bar linkage mechanism, and a thread take-up device is installed on the fourth connecting arm, and a wire management device is installed on the other side above the four-bar linkage mechanism, so The bottom transmission end of the four-bar linkage mechanism is connected with an adjustment device, and the cable management device includes a mounting frame, a connecting rod, a cable management frame and a cable management plate, and the center of the outer wall on both sides of the mounting frame is equipped with a connecting rod. Both sides above the thread management frame are vertically welded with vertical plates. The thread twisting mechanism is composed of a seat tube, a movable column and a curved sponge strip. The thread take-up mechanism of the industrial sewing machine solves the problem of The weaving thread is easy to be entangled and knotted, and there are many lint around the weaving thread body.

Description

technical field [0001] The invention relates to the technical field of a thread take-up mechanism of a sewing machine, in particular to a thread take-up mechanism of an industrial sewing machine. Background technique [0002] When the sewing machine is sewing, in the process of forming the stitches, the mechanism that plays the role of conveying, recovering the needle thread and tightening the stitches is called the thread take-up mechanism. The thread take-up mechanism can be divided into five categories according to the structure and principle, that is, the cam pick Thread take-up mechanism, connecting rod thread take-up mechanism, slide bar thread take-up mechanism, rotary thread take-up mechanism and needle bar thread take-up mechanism. It is the connecting rod of the four-bar linkage mechanism. [0003] The existing thread take-up mechanism does not have the function of arranging the weaving thread in the process of leading the thread. The weaving thread is easy to be ...
