The basic feature common to shuttleless looms is that the weft yarn package is separated from the shuttle, or only a small amount of weft yarn is used to replace the large and heavy shuttle with a small and light weft feeder, which provides favorable conditions for high-speed weft insertion. In the supply of the weft yarn, the package is directly used to enter the weft insertion mechanism through the weft storage device, so that the weaving machine can get rid of the frequent weft insertion movement.
The use of shuttleless looms is important for increasing fabric varieties, adjusting fabric structure, reducing fabric defects, improving fabric quality, reducing noise, and improving working conditions. The shuttleless loom has a high speed and is usually 4-8 times more efficient than the shuttle loom. Therefore, the large-area promotion and application of the shuttleless loom can greatly improve labor productivity.
Due to the perfect structure of the shuttleless looms, and the wide range of materials selected, as well as the processing precision is increasing, coupled with the development of the world's science and technology, electronic technology, microelectronic control technology gradually replaces mechanical technology, shuttleless looms The manufacture is a combination of multi-disciplinary technologies such as metallurgy, machinery, electronics, chemical engineering and fluid power. It integrates electronic technology, computer technology, precision mechanical technology and textile technology into one high-tech product.
The air jet loom detects the total tension of the warp by the tension sensor, and the warp tension change that occurs when the CPU controls the opening, the loosening, the warp, and the warp diameter change, thereby ensuring the warp precision and maintaining a constant tension of the warp. Because the air jet loom uses microcomputer technology and other electronic technologies to control the movement of the whole machine, especially the automatic monitoring of product quality, the production efficiency of the air jet loom is greatly improved. At the same time, the requirements of the air-jet looms for electronic control systems are getting higher and higher, not only for high performance, good stability, convenient maintenance, low failure rate, but also to adapt to the environment of high temperature, high humidity, hairiness and dust. There are also strong anti-interference requirements for power fluctuations and group interference.
