The Develop History of Modern Electronic Jacquard Loom

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 combines modern microelectronics technology and electromagnetic and photoelectric technology. With the cooperation of the textile CAD system and new mechanical mechanisms, it realizes high-speed patternless jacquard, 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 main body of control, 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 Signal, and drive the jacquard information to send *jacquard faucet to implement jacquard control.

The international research on the electronic jacquard opening mechanism began at the end of World War II. By the 1970s, due to the application and development of large-scale integrated circuits and electronic computers, the research on electronic jacquard machines had made significant 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 blossomed, a hundred schools of thought have been contending, and the development momentum has been gaining 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 analysis, it is nothing more than the following components:

1. Electronic program control device: correctly send out the lifting information, with keyboard, display, printing and other functions;

2. The conversion mechanism between electrical signals and mechanical quantities: generally electromagnets are used, that is, the lifting information sent by the program-controlled device is converted into mechanical displacement to realize mechanical control.
