Full servo warp knitting machines have been gradually applied in textiles. Now the full-servo warp knitting machine has good advantages in output, efficiency, pattern diversity and product quality, so it will become the mainstream of jacquard weaving in the future.
The feasibility of the traverse control system based on linear servo motor is analyzed, and the overall design structure of the system is proposed to adopt a three-level distributed control system composed of upper computer, traverse control unit and linear servo actuator. The selection principle of the motion law is analyzed, and according to the selection, the trapezoidal acceleration motion law is modified for the servo drive curve of the bar traverse of the high-speed warp knitting machine. Then select the components of the traverse control system, including the selection of linear servo motors, servo drives, rotary encoders, and grating rulers.
The application of Electrolys servo system in warp knitting machine greatly improves the automation level and production capacity of warp knitting machine, especially in the aspects of warp knitting electronic let-off, electronic traverse and electronic pulling, etc., the overall performance of the machine can be greatly improved. To transform the existing warp knitting machines in China and gradually realize the function of automatic control to meet the needs of product development, which is in line with the characteristics of our warp knitting industry.
