High speed skeining machine

CY215D High speed precision skeining machine 

1:Applied range:

CY215D high speed precision skeining machine is suitable for precision forming of elastic chemical fibers ,like polyester, chinlon  and so on, especially for precision forming of fine denier yarns.

2:Features

• ²  Adoption of electronic yarn guide forming system, forming length is adjustable electronically , and the uniformity of forming density for reeled yarns can be guaranteed.




• ²  Adoption of digital programmable  intelligent control, winding track can guarantee yarns to precision wind and form with  high speed winding at the same time.

  
  

• ²  intelligent constant tension system and  automatic tracking system of overfeeding can be chosen, so that the stability of yarn forming can be guaranteed.

  
  

• ²  Equipped with single spindle operation control, yarns can be loaded and unloaded freely. It is convenient to operate with reasonable transmission, compact structure, beautiful appearance;

  
  

• ²  Each spindle of the whole machine is drove by independent brushless DC motor, Productivity is improved , power consumption is reduced at same time , more than 30% power is saved compared to similar machines.

3.4  Winding unit structure

3.4-1  Yarn tension device

One tension method is weighted gate tension device, based on the different yarn, increase and reduce pressure to adjust the yarn tension, to get the good package from the stable tension.

Another tension method is constant tension controller, ensure the yarn tension precision, can make stretch yarn such as difficult to good forming to good forming shape.

Third tension method is automatically control tension of stepper motor, according to the tension requirement of pressure sensor  to provide tension data as needed.

3.4-2 Yarn break automatic detection system

Adopt photoelectric or level type yarn sensor, send the signal to controller when yarn brake, also turn off the motor running automatically; At the same time, the signal lamp shining to prompt the machine have already stop.

3.4-3Overfeed device

Overfeed device use independent motor for synchronous operation. According to different yarn, overfeed ratio 100%-200% can be arbitrarily set, to make sure the winding forming beautiful.

 

3.4-4 Constant tension device

When adopt constant tension device, install a pressure sensor at top of constant tension. Constant tension device adopt a overfeed pulley which driven by a sensitive, independent drive motor. Yarn wind this overfeed pulley through pressure sensor and reach take up bobbin, after set the pressure, through sensor's signal to control. When over pressure, overfeed increase the speed to feed yarn; When pressure are smaller, overfeed decrease the speed to feed yarn, to reach the yarn tension consistent and the good yarn forming.

 

 

3.5 Electronic yarn guide forming device

Via positive inversion of stepper motor, adopt wire rope to drive and take fixed yarn guide head, in the running of the motor, making yarn guide head do back and forth at high speed winding and forming.

We have research and development the control system of yarn guide winding forming of stepper motor, realize yarn guide forming automation:

 

With the help of Wuhan Textile University, we have research and development the control automation system of yarn guide forming of stepper motor; This system can make precise control the positive inversion distance of the stepper motor, the running can reach 1200 rounds per minute, we can change path freely in the movement path at the same time. So that the winding forming can according to the need density, soft side, different retract side angle, forming length etc.. To realize the forming electrical automation.
