A two-for-one twisting machine

Abstract

The invention discloses a two-for-one twister, which belongs to the field of textile machinery. Existing two-for-one twisters have the problems of high energy consumption and high noise due to the unoptimized shape of the balloon. The present invention includes a spindle installed on the frame, a spindle drive motor, a yarn collector, an overfeeding device, a coiling device and Control system, the radial yarn hole on the spindle twisting disk communicates with the hollow inner cavity of the spindle rod, the spindle rod is equipped with a tensioner, and a yarn sensor is installed on the yarn path between the yarn collector and the overfeeding device to detect the yarn For linear speed and yarn tension, a motor sensor is installed on the spindle drive motor to detect the motor speed and motor current; the overfeeding wheel of the overfeeding device is driven by a separate motor, and the control system uses the yarn linear speed and yarn tension fed back by the sensor , the speed of the spindle drive motor and the motor current are the control parameters, control the operation of the motor connected to the overfeed wheel, adjust the yarn pulling speed, and make the yarn tension value meet the requirements of the best shape of the yarn balloon that can minimize the wrapping angle. Realize energy saving and noise reduction.

Description

technical field

[0001] The invention belongs to the technical field of textile machinery, and in particular relates to an energy-saving two-for-one twister with low energy consumption and low noise. Background technique

[0002] The two-for-one twister is a twisting device that can realize two twists in one turn. The yarn to be twisted is drawn from the static yarn feeding package, and passes through the hollow spindle bar from the top of the spindle. With one revolution of the spindle bar, the yarn gets a twist, and then the yarn flows from the lower end of the hollow spindle bar. The transverse eyelets of the twisting disc lead out to the yarn collector leading upwards. The twisting disk rotates with the spindle, and the yarn adds another twist as the horizontal eyelet rotates to the fixed point of the yarn collector. During the rotation of the spindle, the yarn between the transverse hole of the twisting disc and the fixed point of the yarn collector will form an air ci...
