Two-for-one twister

Abstract

The invention discloses a two-for-one twister, and belongs to the field of textile machinery. The problems that the energy consumption is great, and noise is high due to the fact that an optimum ballooning shape cannot be reached exist in the existing two-for-one twister. The two-for-one twister comprises a spindle mounted on a rack, a spindle drive motor, a yarn collecting device, an overfeeding device, a coiling device and a control system, wherein a radial yarn passing hole in a spindle twisting tray is communicated with a hollow inner cavity of a spindle blade; a tensioner is arranged on the spindle blade; a yarn sensor is arranged in a yarn path between the yarn collecting device and the overfeeding device and used for detecting a yarn speed and yarn tension; a motor sensor is arranged on the spindle drive motor and used for detecting a motor speed and motor current; an overfeeding wheel of the overfeeding device is driven by a separate motor; by taking the yarn speed, the yarn tension, the spindle drive motor speed, and the motor current fed back by the sensors as control parameters, the control system controls the motor connected with the overfeeding wheel to operate, adjusts a yarn pulling speed, and ensures that a yarn tension value meets a requirement of the optimum yarn ballooning shape capable of allowing a wrapping angle to be minimum; and energy conservation and noise reduction are achieved.

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 ...
