The production of jacquard fabrics has gone through a long and tortuous process from purely manual to mechanical jacquard machines to today's electronic jacquard machines. The opening of the electronic jacquard machine integrates modern microelectronic technology and electromagnetic and photoelectric technology. With the cooperation of textile CAD system and new mechanical mechanism, high-speed non-pattern jacquard is realized, which greatly improves labor productivity and product quality. The design scheme of the electronic jacquard control part takes a general-purpose microcomputer or industrial computer as the control body, uses data sources in the form of disk files, network files, etc. to meet the requirements of different weaving environments, and develops corresponding interface circuits to read jacquard information and generate timing sequences The jacquard information is driven and sent to the jacquard faucet to implement the jacquard control.
The international research on electronic jacquard opening mechanism began at the end of World War II. In the 1970s, due to the application and development of large-scale integrated circuits and electronic computers, the research on electronic jacquard machines has made great progress.
In 1983, the electronic jacquard machine was exhibited as a prototype at the Milan Textile Machinery Exhibition. Since then, many jacquard machine manufacturers have included it in their development plans. It can be said that since the 1980s, the textile industry has flourished, a hundred schools of thought contend, and the development momentum very good.
Compared with other mechanically controlled jacquard machines, electronic jacquard machines have creative changes in pattern control. Although different electronic jacquard machines have different structures, from the perspective of principle, they consist of the following parts:
1. Electronic program-controlled device: correctly send out comprehensive information, with functions such as keyboard, display, and printing;
2. Conversion mechanism between electrical signals and mechanical quantities: electromagnets are generally used, that is, the comprehensive information sent by the program control device is converted into mechanical displacement to realize mechanical control.
