Problems solved by technology

Because carbon fiber is not wear-resistant and has poor shear strength, the cross-sectional shape is a rectangle with a large ratio of length to width. The fabric requires that the weft yarn should be flat and free from twist and damage. Therefore, all existing weft feeders cannot meet the requirements. Requirements for Weaving Carbon Fiber Fabrics

Abstract

The invention provides a weft storage device without twist change. Twist of weft yarns cannot be changed in backing-off, storage and guiding processes, and abrasion to the yarns is low. The weft storage device comprises a backing-off device, an induced draft storage device and a detecting device, wherein the backing-off device is used for realizing backing-off of the yarns, the induced draft storage device is used for storing the backed-off yarns, and the detecting device is located on the induced draft storage device and used for detecting whether backing-off of the yarns is normal or not. A servo motor drives a cheese to rotate via a cheese bobbin, active driving radial yarn backing-off is realized, the twist of the weft yarns cannot be changed in a backing-off process, optoelectronic pairs mounted on two sides of a transparent hard tube are used for detecting signals of the weft yarns, the length of a stored weft yarn at a certain moment is confirmed by means of processing and comparing detection signals of the two groups of optoelectronic pairs within a special time, accordingly, whether weft guiding faults are caused or not and whether the yarn storage quantity is normal or not are judged, a weaving machine is controlled to stop running or the rotation speed of a weft storage motor is adjusted according to judgment results, the weft storage quantity is adjusted finely, and reasonableness of the yarn storage quantity is guaranteed.

Description

technical field [0001] The invention relates to a weft storage device, in particular to a weft storage device without twist change. Background technique [0002] With the wide application of carbon fiber composite materials, the demand for carbon fiber multi-layer woven fabrics continues to grow. Currently, hand-woven carbon fiber multi-layer woven fabrics cannot meet social needs in terms of production capacity and fabric quality. The development of weaving equipment for weaving carbon fiber multi-layer fabrics must be equipped with a weft feeder, but the existing various types of weft feeders will change the twist during the unwinding of the weft yarn from the bobbin, the storage of the weft yarn, and the weft insertion process. There is a certain degree of friction against the weft. Because carbon fiber is not wear-resistant and has poor shear strength, the cross-sectional shape is a rectangle with a large ratio of length to width. The fabric requires that the weft yarn ...
