Shanxi Jingwei Chemical Fiber Machinery Co., Ltd. launched a redesigned version of KJKV618, the standard version KJKV718 and the top version KJKV818 for the 2019 polyester polyester nylon composite yarn based on the original size KJKV518. At the same time, the water-supplied refrigeration equipment has stable operation and low cost of single spindle, and has made outstanding progress in electrical automation and energy-saving efficiency.
We will soon launch more improved modules of this model before the end of 2019, accepting the transformation of old equipment similar to this model, welcome to inquire.
1.1 Product use
Parallel drafting winding machine ( JWKV518 (II) ) is used for polyester yarn, nylon and polypropylene filament production in the process of drafting and winding . The polyester filament (UDY.POY) is spun out by spinning machine,then it is drawn,wound and molded by this machine, to form a certain size, strength, elongation and other physical properties, to meet the requirements of weaving, warping and other post process.
1.2 Product feature

Single spindle winding
Full tube rate
No interference from each tube
Wide range of spinning
Improve production efficiency
Advanced control system:
Synchronous motor variable speed drive technology, convenient adjustment
Fine adjustment of spinning tension
Perfect forming and convenient unwinding.

3. Process calculation
Code name and meaning
| V1 | Line speed of roller, m/min | n | Motor speed, RPM/min |
| V2 | Line speed of hot plate, m/min | i1 | Draft ratio of zone 1 |
| V3 | Line speed of cold plate, m/min | i2 | Draft ratio of zone 2 (wire out speed) |
| V4 | Line speed of friction roller, m/min | i | Total draft ratio, times |
| f1 | Frequency of roller drive motor, Hz | e | Relaxation ratio(over feed rate,OFR) |
| f2 | Frequency of hot plate motor, Hz | α | Helix angle, degree |
| f3 | Frequency of cold plate motor, Hz | H | Transverse movement, mm |
| f4 | Frequency of friction roller motor, Hz | F5 | Frequency of winding motor, Hz |
Calculation result:
V1=0.124×π×30/60×20f1=3.89557×f1, (194.7785 m/50Hz)
V2=0.09×π×30/60×24/14×20f2=4.847×f2, (242.35 m/50Hz)
V3=0.10×π×30/48×24/14×30f3=10.97976×f3 (504.8988 m/50Hz)
V4=0.108×π×30/48×30f4=6.361725×f4 (318.08625 m/50Hz)
e%=(1-V4/V3)%=(1-0.63×f4/f3)%
α, anti aliasing Δwave ± Hz
F5=0.372×V3×sinα=3.75668×f3×sinα
i1=1.2442×f2/f1
i2=2.0833456×f3/f2
