Features
1.Semi-automatic joint
Use stepper motor to feed cotton alone, combined with professional computer software parameter design, to realize joint section control. To improve the quality and success rate of joint.
2.Single spindle guiding technology
The semi-automatic connection device is equipped with the single spindle motor yarn leading unit, and the action response is more sensitive. The advanced and reliable digital joint technology ensures the joint efficiency and quality.
With the cooperation of electronic transverse movement, the yarn speed can reach 200 meters/min, so as to obtain more production capacity.
3.Traverse structure and spinning forming
Adopt the internationally leading electronic traverse mechanism, within the scope of the process through a computer screen can be adjusted winding Angle, lateral dynamic differential micro cycle and cycle variation, reduce or eliminate the chrysanthemum cone yarn core. Ensure sequence of normal unwinding after cone yarn.
4.Spinning box
The two spinning machines are equipped with high-precision process components and rotor bearings u p to 12 rpm to meet customers' pursuit of high-end yarns and requirements for high speed, high quality, and high efficiency.
