Circular knitting pulling up device, commonly known as rolling machine.
Action
1 pulling tension evenly, so that the needles reasonable force to extend the life of the needles, knitting ensure normal;
2 the knitting and pulling up speed to match;
3 can control the maximum winding length.
classification
Knitting machine pulling up device can be divided into two categories:
1 constant torque electric traction cloth
Constant torque electric traction is continuous roll cloth roll cloth by pulling stepless electronic control constant torque motors. Advantage is that the motor shaft is not a constant power output power, but with constant torque output power, good linearity characteristics, torque fluctuation is small, and the load balance can be maintained. Use constant torque motors to drive the initiative curl curl, simple structure, winding stable, good continuity, torque constant, fast and convenient adjustment, after a long shutdown boot without manually preload cloth.
2 Mechanical stretch cloth
Mechanical stretch the cloth is pulled through the gear shift cloth, by changing the amount of curl to adjust the different stalls, lower manufacturing costs, speed adjustment between each gear intermittent points. To this end, more than 120 segments are generally used to adjust the speed reduction gear to adjust the speed of the breakpoint, thereby increasing the number of gearbox change gear, the structure is more complex.
