Due to the variety of weaving varieties and short cycle, the warp knitting machine has gradually gained people's attention in the fierce market competition. At present, the mechatronics of warp knitting machines has become a development trend. Although there have been more in-depth studies on the electronic warp and electron pulling system of warp knitting machines in China, there are still few studies on the motion of electronic warping of warp knitting machines.
Electronic traverse system actuator
The electronic bar traversing mechanism using the servo motor system can eliminate the bulky disk/chain block and the stroke changing device, and the servo motor is used as the source power of the bar traverse mechanism. Each of the warp knitting machines is equipped with a servo motor, and the rotation of the servo motor shaft is driven by the mechanical conversion mechanism to traverse the bar.
The servo motor-ball screw traverse mechanism is mainly composed of a servo motor, a timing belt transmission mechanism, a ball screw pair, a linear guide and a slider, a ejector rod and a tension tension spring. The motor shaft and the ball screw are connected by a synchronous belt transmission structure, and the ball screw drives the slider mechanism to move linearly, and one end of the slider is provided with a ejector rod and acts on the bar by tension tension spring. The operation process of the bar traverse is as follows: after the motor receives the control signal for traverse, the motor shaft rotates by a corresponding angle of the set motion curve, and the ball screw of the motor shaft connected by the timing belt transmission mechanism also rotates accordingly. After a certain proportion of angles, the ball screw drives the matching nut to convert the rotary motion into a linear motion, thereby realizing the operation of pushing the bar to traverse.
The most important parts of this bar electronic traverse structure are the servo motor, timing belt drive and ball screw construction. The servo motor can accept the signal from any angle of the spindle to drive the bar to make the traverse, which has high precision and convenient control. The function of the ball screw is to make the motor's rotary motion into linear motion; the timing belt drive mechanism is used to connect the motor shaft and the ball. The screw rod has the function of damping and buffering the system.
