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, and relates to the technical field of thread take-up mechanisms of sewing machines. Specifically, the thread take-upmechanism comprises a base, a four-bar linkage mechanism, a thread take-up device, a thread arranging device and an adjusting device, wherein the four-bar linkage mechanism is mounted above the base;a fourth connecting arm is connected to one side of the upper part of the four-bar linkage mechanism; the thread take-up device is mounted on the fourth connecting arm; the thread arranging device ismounted on the other side of the upper part of the four-bar linkage mechanism; the bottom driving end of the four-bar linkage mechanism is connected with the adjusting device; the thread arranging device comprises a mounting frame, connecting rods, a thread arranging frame and a thread arranging plate; the connecting rods are mounted in the centers of the outer walls of the two sides of the mounting frame; vertical plates are vertically welded to the two sides of the upper part of the thread arranging frame; and a thread twisting mechanism is composed of a seat cylinder, a movable column anda curved sponge bar. According to the thread take-up mechanism of the industrial sewing machine, the thread arranging device is arranged, so that the problems that weaving threads are easily wound andknotted and fluffs around thread bodies of the weaving threads are relatively numerous are solved.

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 ...
