Automatic yarn changing device

Abstract

The invention relates to an automatic striping device with simple mechanism, low price and low failure rate, belonging to the textile mechanism. The automatic striping device comprises an outer casing, a tool-rest fixing seat which is fixedly arranged on the outer casing, a yarn-selection fixing seat, a connecting seat and a main shaft which is fixedly arranged between the yarn-selection fixing seat and the connecting seat on the outer casing. An upper end and a lower end of the main shaft oppositely revolve and are respectively sheathed with a collecting-cutting rotary block. An L-shaped control board is oppositely and rotationally sheathed between the upper and lower collecting-cutting rotary blocks on the main shaft. A groove is cut on the tool-rest fixing seat, a tool-rest board is oppositely and rotationally arranged in the groove, a tension-spring is connected with the tool-rest board and the other end of the tension-spring is fixed onto the outer casing. An arc-shaped connecting cut is arranged at the right end of the tool-rest board, and the rim of the connecting cut is greater than 50 percent of the arc. A link rod is connected in the connecting cut, the left end of the link rod is provided with a connecting head which is articulated with the connecting cut, and the connecting head and the connecting cut are on the same plane. The right end of the link rod clings to an expansion spring, and a resetting pin is arranged in the middle of the link rod and clings to the control board.

Description

technical field [0001] The invention relates to a thread regulator used in the textile industry, in particular to an automatic thread regulator. Background technique [0002] At present, all kinds of domestic knitting enterprises mainly use circular yarn-dyed jacquard circular knitting machines for production. Since the 1980s, with the in-depth development of my country's reform and opening up, domestic knitting enterprises have increased rapidly, and large circular knitting machines have become more and more popular among knitting enterprises. of favor. With the changes of the times, the automatic thread adjusters of large circular knitting machines produced by domestic circular knitting machine manufacturers are purchased from European countries such as Japan, Taiwan, and Germany with developed textiles. The thread adjusters produced in Japan and Taiwan are relatively small. , There are many parts, the internal space is small, and the failure rate is high, resulting in the...

AI Technical Summary

Problems solved by technology

[0003] 1. Unrepairable defects such as multi-lines and large holes appear after line selection failure

[0004] 2. Sometimes when the knife is closed, the thread flies out of the knife edge, causing flying yarn, which causes a large material consumption for the weaving factory

[0005] 3. Severe banding on the edge of the knife causes many defects in the coloring of the cloth surface

[0006] The thread regulators in Germany and other European countries are relatively mature, but they are large in size, have many parts, and complex structures. It is difficult to replace wearing parts, easy to misuse, and expensive.
