Problems solved by technology

[0002] Judging from the current domestic electronic jacquard machine market, the solenoid valves used in domestic electronic jacquard machines are similar in structure to the solenoid valves produced by foreign manufacturers such as BONAS and STAUBLI, and their quality still has a certain gap compared with imported solenoid valves. And with the deepening of use, a series of problems have also appeared in the use of foreign solenoid valves, such as: BONAS solenoid valves have high energy consumption, and their bulky size leads to bulky equipment, which is not conducive to the maintenance and development of large-needle jacquard machines; The STAUBLI solenoid valve has a compact structure but poor heat dissipation, and the complex booster and needle suction mechanism is prone to failure. The semi-open structure in which the pulley is fixed in the solenoid valve assembly makes the requirements for the sealing of the electronic jacquard machine very high, which greatly improves the Difficulty in manufacturing equipment and increased requirements for the environment in which equipment is used

[0003] However, the use of domestic electronic jacquard machines has not been well developed in the market. The biggest reason is that the performance and reliability of the solenoid valve, the needle selection part in electronic jacquard machines, has not been well resolved.

All manufacturers produce solenoid valves by themselves, but no manufacturer has conducted in-depth research and analysis on the working principle, use requirements, and material characteristics. They are all low-end imitations and cannot be surpassed.

[0004] Therefore, if you use domestic electronic jacquard machines, you have to worry about the quality and inconvenient maintenance.

Using foreign electronic jacquard machines, although the quality is guaranteed, the cost of equipment and accessories is high, and the capital recovery period is long. Therefore, it is extremely necessary to develop and design a reasonable needle selection device, which can reflect the advantages of convenient maintenance, high efficiency and reliability, and low energy consumption.
