Mechanical Valve

The shuttleless loom with high performance main muffler shell opening device is an important technical equipment in the new generation of national textile machinery. According to the development demand of shuttleless loom with high speed, automation and intelligence, through the dynamic analysis of opening motion, the structure is improved, the cam design is optimized, the vibration noise is reduced, and the high-speed weaving efficiency is improved. The embedded real-time control technology of independent muffler number system and synchronous joint control between the opening device and various looms is studied to improve the degree of automation and product adaptability Realize the localization of high performance shuttleless loom. The total investment is 100 million yuan, the annual production capacity is 9000 sets, forming the supporting process technical specification; during the implementation period, the new output value is 480 million yuan, the profit and tax is 64.5 million yuan, and 3-4 national invention patents are obtained. In engineering design, the main technical parameters of gt409, ed607 high-speed active electronic dobby and gt623 high-speed active cam opening device are 700R / min, 1000r / min and 1200R / min, which can meet the needs of various looms.
