Cloth defect marking device and cloth production device

Abstract

The invention discloses a cloth defect marking device. The cloth defect marking device comprises yarns, a yarn stretching mechanism, a yarn pulling rod, a yarn pushing rod, a crochet hook and a yarn cutting-off bar, wherein the yarns are knotted; the yarn stretching mechanism is used for stretching the yarns into straight lines; the yarn pulling rod is used for pulling out the straight yarns from one side of cloth; the yarn pushing rod is used for pushing the yarns which are pulled out by the yarn pulling rod to the other side of the cloth so that hoops are formed; the crochet hook penetrates in the hoops and the cloth and hooks out the yarns so that slipknots are formed; and after the slipknots are formed, the yarn cutting-off bar is used for cutting off the yarns. The invention also discloses a cloth producing device which comprises the cloth defect marking device. As long as defect signals exist, a series of actions can be finished quickly, and the slipknots are formed at the edges of a cloth piece by the yarns and stand for defects. Pollution on the cloth is low, the cost is also low, marks are easy to remove, and industrial large-scale popularization and utilization are facilitated. The cloth defect marking device has a wide application prospect when used in a cloth production line.

Description

technical field [0001] The invention relates to the field of cloth production equipment, in particular to a cloth defect marking device and a cloth production device. Background technique [0002] Whether it is woven or knitted fabrics in textile production, there will be defects. And there are corresponding national standards for fabric defects. But there is no uniform standard on the marking of fabric defects. Every textile factory has its own set of methods when marking fabric defects. The most typical manual marking method is to manually thread a needle and tie a knot. And this knot is a slipknot. Once the defect is repaired, the mark will be untied immediately, so that the mark of this defect will be lifted accordingly. [0003] With the improvement of the mechanization of defect identification, people have also begun to use mechanized marking systems to mark defects.

Problems solved by technology

The obvious defect of these marks is that it will pollute the cloth itself

Moreover, the cost of markers during use is relatively high
