< p > Wang Minqi: technological innovation is the secret of rapid development of the five oceans. You can see the application of many new products and new technologies that we independently developed in the workshop. At present, there are only a few enterprises in China producing high-speed double needle bed warp knitting machines. The five overseas pioneered the industrialization promotion and application of the product, and it has been purchased and used by Changshu's Qunying, Dafa, Dongfang, Fujian Xintai, Meng FA and other domestic manufacturers with a certain strength to produce all kinds of high-grade spacer fabrics, pile fabrics and other products. < /p >
< p > GE2296 high-speed double needle bed warp knitting machine project is in accordance with the State Council's industrial transformation and upgrading plan (2011-2015 years).
In 12th Five-Year, the national special project on intelligent manufacturing equipment development is an efficient intelligent high-speed double needle bed warp knitting machine, which is developed to meet the development requirements of the national modernization and the urgent need of industry transformation and upgrading. It is in line with the national development and Reform Commission's plan to accelerate the implementation of < a href= "//www.sjfzxm.com/news/index_c.asp > > textile machinery < /a > major technology and equipment. The project product can meet the large demand of the new generation high-speed double needle bed warp knitting machine both at home and abroad. < span style= "font-family: song body; font-size:small >".

< p > host: what is the overall design idea of GE2296 high-speed double needle bed warp knitting machine? < /p >
< p > Wang Minqi: GE2296 high-speed double needle bed warp knitting machine mainly revolves around the Russell high speed double needle bed warp knitting machine technology, breaking through a series of key technologies of high-speed double needle bed warp knitting machine. The project has been innovated in designing and using double sided multi phase and multi crank crankshaft drive, with high precision connecting rod short running tongue needle and high-speed knitting. The high sensitivity temperature control system ensures that the whole set of transmission mechanism, hanging shaft, pendulum shaft, ring forming machine and needle distance are not affected by ambient temperature. The multi speed multi segment intelligent let off and traction system is optimized to ensure the instantaneous speed change. The inertia of the rotation of the shaft does not affect the accuracy of the let off. It ensures that the let off amount is exactly the same as that of the immediate drawing density, and meets the high quality requirements of all kinds of density fabrics. The maximum weaving speed is over 1000rpm. < /p >
P: host: compared with the international spinning machine market, there is still much room for improvement in our products. Please briefly introduce the technological innovation points of GE2296 high-speed double needle bed warp knitting machine in high speed, stability, reliability and energy saving. < /p >
< p > Wang Minqi: first, we studied the high-speed motion system of double needle bed warp knitting machine based on kinematics and dynamics principle. We designed and used the double needle bar loop movement mechanism with double crankshaft and connecting rod, broke through the technical problems of multi phase, multi crank crankshaft and connecting rod, ensured the accuracy of action coordination of each ring forming machine, reduced the number of components, compact space, reduced impact force, reduced noise, avoided resonance, and the production speed reached 1000rpm. The production efficiency was 1.25 times that of the international similar products. < /p >
< p > Second, a short cycle tongue needle double needle bed forming model was established, and the motion coordination of short movement Tongue Needle looping mechanism was developed. A reasonable displacement curve of speed and acceleration was designed, which shortens the moving process of each ring forming machine, reduces the time of circle formation, improves the efficiency of circle forming, reduces the damage of fiber, and ensures the cloth quality < /p >.
< p > Third, using three-dimensional software to simulate the dynamic and static balance of the double-sided crankshaft, creating a double-sided crankshaft, static balance without weight balancing, direct installation technology, shorten the assembly time, ensure the stability of the machine operation, and reduce the noise of the machine. < span style= "font-family: song body; font-size:small >".

< /span > < /p >.
< p > Fourth, using 3D software to carry out the dynamic simulation and operation of the whole machine, focusing on the simulation and improvement of the movement coordination curve of the tongue needle, sinker and guide needle, optimizing the matching of the ring forming machine and the whole machine structure, ensuring the reliability of the high-speed running of the machine and the quality of the fabric. < /p >
< p > fifth, a double-sided crankshaft constant temperature lubrication system has been developed, which solves the key technologies of constant temperature and even lubrication for multi phase and multi crank crankshafts. The lubricating oil circulation system not only carries out constant temperature cycle in the tank, but also transfers the lubricating oil to the two pendulum shaft and the lifting shaft to carry out the recirculation, ensuring that the oil tank temperature and the overall temperature of the three axis are kept at 34 ~35 C, so that the temperature of the whole machine is not affected by the ambient temperature, so as to ensure the accuracy of the needle distance, ensure the high-speed operation of the whole machine, and prolong the service life of the machine. < /p >
< p > host: what is the cost of this < a href= "//www.sjfzxm.com" > Warp knitting machine < /a > what benefits can it bring to the enterprise? < /p >
< p > Wang Minqi: after the success of our development, each unit has a selling price of about 800 thousand yuan, and its speed, performance and reliability are better than that of international similar products. The price is less than 20% of the international similar products, so it has strong market competitiveness. < /p >
< p > in addition, the equipment has the characteristics of high efficiency, high performance and low noise. At present, the warp knitting machine can achieve an annual output of 100 units, bringing about 80 million yuan in sales and 21 million yuan in profits and taxes. At the same time, the "GE2296 high-speed double needle bed warp knitting machine" project can also save energy, reduce land use, reduce labor costs, increase output and improve labor productivity, provide equipment support for the transformation and upgrading of enterprises in a timely manner, and contribute to enhancing the international competitiveness of China's national industry. < /p >
