With the development of electronic technology, textile technology from the initial Jacquard mechanical needle selection manner to the current electromagnetic needle selection methods. Jacquard mechanical and electronic jacquard compared structure is relatively simple, spent more flexible and reliable control. Electronic jacquard machines are based on the IPC-based embedded microcontroller and the two programmers, the latter than the former in reliability, cost and other issues, has advantages. Jacquard is open use jacquard weaving pattern to achieve a diverse loom, the traditional Jacquard loom from the spindle drive are through to the other institutions, agencies and deceleration, such as spindle to achieve, including two sets of deceleration, more a universal coupling and clutch, complex institutions not only increase the cost of manufacturing and lower transmission efficiency, reliability of the components are greatly reduced, but also jacquard work relatively noisy one of the reasons. We found particularly in the clutch when a high-speed operation casual yarn, affecting its efficiency. This is also preva lent at home and abroad Jacquard phenomenon. Based on this topic KT566J (B) Jacquard improvements, a direct-drive servo motor system, the abolition of the original vertical transmission mechanism. Its advantage lies in weaving through the control computer downtime may arbitrarily set or change looms IMIS-position, and simplify the institutions transmission chain. At the same time improving the efficiency of the Loom, reduce noise, enhanced reliability of the components are. Filled a direct-drive servo motor Jacquard gaps in the country.
