The Design And Optimization Of WH-6F Computer Hosiery Machine’s Looping Mechanism

Modern advances in textile technology for the rapid development of the textile industry to provide technical support, quality, efficiency, energy conservation has become a major development trend of textiles. Hosiery industry in our province in the textile industry occupies a very important position, many export-oriented products socks, but because of domestic Waji the prototype to copy the main, and socks design means a single, leading to most of the domestic Waji there are still features a simple, low production efficiency, product quality is not high so the lack of market competitiveness. WH-6F computerized hosiery machine’s as a typical fully automated computer hosiery machine, using modern mechanical design tools, the models in-depth analysis and research, breaking the monopoly of foreign technology is necessary.Dissertation, theoretical analysis and experimental verification of a combination of methods, WH-6F computerized hosiery machine’s knitting and weaving principle agencies systematically analyzed in order to establish the dynamic model pushed the needle into the ring and pick mechanism. On this basis, the use of SolidWorks modeled looped research institutions, combined with ANSYS completed motion simulation into the ring mechanism through high-speed photography to verify the reliability of the simulation results. Finally, the key components are optimized. The main research results are as follows:(1) Analysis of the functional components and key components. WH-6F computerized hosiery machine’s pushed the needle into the ring and pick the bodies to determine the needle go when knitting knitting needle trajectory, with socks and knitting, socks head when double pick needle double press works, for the calculation of key institutions to provide a theoretical basis.(2) Analysis of the relevant parameters have been key components, as follows:Install yarn guide seat height is 72mm; water chestnut about the length and width were 39.9mm,21.1mm; length and width of the water chestnut were 30.5mm,15.5 mm; the total length of the shank pick is 58.5mm; total length pushed the needle bar is 58.2mm. By calculating the parameters of analysis for the dynamics of the elastic ring mechanism to provide the basis for the process parameters.(3) Through the needle during exercise stress analysis to obtain the needles affect the smooth movement of the acceleration values issues. When the value is less than zero out the needles triangular track, exercise the remaining cases to be bound by the needles triangular track. Concluded that the size of the needles and the needles triangular shaped variable impact force is proportional to jerk acceleration is proportional to the needle position by varying number of knitting with the triangular collision force instant analysis.(4) For the pick, stress analysis when the needles pushed the needle to give the butt of any cross-sectional deformation not remain flat, while according butt displacement size, it can accurately determine overhangs pushed the needle process knitting needle case of stress and strain butt.(5) Based on SolidWorks creates WH-6F computerized hosiery machine’s knitting agency model, the modeling techniques, modeling, modeling steps, etc. in-depth analysis. ANSYS combination of needle motion simulation analysis, the process of knitting needle displacement, velocity, acceleration and stress changes, high-speed imaging experiments to verify the reliability of the simulation results.(6) Using ANSYS optimization features of the stitch, needle pick bezel, push the needle bar board to optimize the design, so that the maximum stress pushed the needle and pick between the knitting needle bar down from the original 220N 150N, for the computer Optimal design of socks provides a theoretical basis.Papers to WH-6F computerized hosiery machine knitting weaving principle and to analyze the dynamic characteristics of completed entity modeling and kinematic simulation and optimization design for the key parts, on the computerized hosiery machine improvements have corresponding reference value.
