What is the ability to detect broken warp threads in textile equipment
The ability to detect broken warp threads in textile equipment is relatively good, which is reflected in the following aspects:
1. High detection accuracy: The warp stop strip is usually composed of two electrodes and an insulating layer that isolates them. The warp stop piece is inserted on the warp stop strip, and the yarn passes through the warp stop piece. When the yarn is not broken, the war
The ability to detect broken warp threads in textile equipment is relatively good, which is reflected in the following aspects:
1. High detection accuracy: The warp stop strip is usually composed of two electrodes and an insulating layer that isolates them. The warp stop piece is inserted on the warp stop strip, and the yarn passes through the warp stop piece. When the yarn is not broken, the warp tension causes the warp stop piece to suspend above the warp stop strip; When the yarn breaks, the warp stop piece falls down and conducts the two electrodes of the warp stop strip, thus correctly detecting the broken warp condition. This contact detection method can detect any broken warp yarn, with high reliability and is not easily affected by factors such as textile factory flying flowers, gradually replacing the photoelectric broken warp detection device.
2. Quick detection: A warp break detection device based on the principle of resistance voltage division, with a detection time of less than 100ms, can quickly detect and send a signal after a warp break occurs, causing the loom to stop in time.
3. High accuracy of meridian break position detection: Some improved meridian break strips combined with specific detection systems and data processing methods can achieve correct detection of meridian break positions. For example, based on the law of resistance, a method for detecting the broken warp position of weaving machines uses materials with high resistance values per unit length to make warp stopping strips, and designs data processing methods to remove the influence of contact resistance. The measured distance error is between 0.04-1.09cm, which can meet the requirements of finding the broken warp position of fine, high-density, and wide width fabrics. There are also devices for detecting broken warp positions based on the principle of resistance voltage division, with a detection accuracy of up to 1cm, and equipped with light-emitting diodes to indicate the broken warp position, which can meet the production needs of textile sites.
