REWINDING NEW TECHNOLOGY

New Rewinding technology advantage and theory description:

Rewinding and weaving are connected closely, application and research are in synchronous developing in these field. It is very deep affection to next weaving process by package quality. The package with uniform density and good waxed will raise the weaving efficiency.

SUNKING REWINDING features:

Perfect yarn winding; rewinding is a very special skills required production progress, till now, the traditional winding machine has not produced internal and external perfect uniform density package, the reason is winding characteristic and the package from full to empty winding during the tension changed, to the yarn ribbon and the density uneven. Sunking rewinding machine, using easy yarn path design, absolutely eliminate the yarn angle damaged during the path, and eliminate affecting yarn hair and other problem, thanks for the digital tension control system and optimized anti-ribbon technology, rewinding max. speed up to 1600m./min, the package density can reach radial density completely uniform.

Winding traverse:

In the high speed weaving process, high speed yarn unwinding due to yarn twist will by passive winding traction speed should be the influence of the centrifugal force of the force and the gas ring cyclotron, in the axial end and yarn unwinding point and into the gas ring of the separation point will produce twist stress caused by the releasing of the hairiness bond issues.

Fox example: 4 inch drum type: traverse [101mm], reduction of the yarn cross angle and 1.5 groove winding, axial separation corresponding yarn release of friction coefficient will synchronous decrease exponentially, caused by the axial unwinding balloon stress will also be synchronized to narrow, yarn back around the bond should force and friction force reduced, effectively avoiding the unwinding tension fluctuation and influence of yarn hairiness and yarn dry strength and other defects, very adapted to high speed loom weft winding.

Tube hold device:

1〉Using side open patent holding design, the new clamping structure small chuck using static positioning lock, open side arm the structure on the right side of the handle, and adapt to the right hand operating habits of humanized design, loading the bobbin by its structure design and automatic locking, unloading yarn just to the right push can be simply and quickly complete, can directly reduce operator fatigue strength.

2〉Optional larger diameter clamping device, yarn diameter up to 350mm / greater of yarn containing up to 3-4kg, especially applicable in weaving, in order to reduce the replacement frequency and amount of yarn, reduce operating frequency frequent replacement labor strength of yarn, reduce the rate of loom stop, directly improves the production efficiency of loom.

Overfeeding:

Overfeeding device using digital tension, integrated structure and simple threading path. High sensitivity and real-time sensing of the tension sensor, the detection range of up to 0.1g, can be in Real time monitoring and feedback to the processing unit in the whole winding process, the central processing unit is actively responding / driving device to fully control the yarn tension and display the tension state. Regardless of how changes in the winding winding speed even yarn in faded around when, under the natural tension due to bond and other factors caused by the tension of the moment of the random variation, and feeding the yarn from full pipe to the air traffic control diameter becomes small situation, winding tension always work in constant set value.

1〉The initial winding end of the yarn is made of synchronous motor, and the self cleaning of the initial tension device is used to eliminate the tension fluctuation caused by the yarn hairiness residue.

2〉The optimization and upgrading of the overfeeding wheel; the yarn is more widely used, high hardness solves the drawbacks from the early carbon fiber material easy to wear and tear of the, overfeed round its low friction, can effectively avoid the yarn hairiness, extremely suitable for full-time high speed winding.

Electronic System:

1〉According to the principle of random winding of the slot, the optimized software is characterized by the regional overlap of the diameter. The concentrated treatment is carried out, and the yarn is changed in the overlapping area.

2〉Hotoelectric state optimization instructions; state can visually remind and supervise the operators to discover and solve problems quickly.

In order to get a uniform density of yarn and yarn winding tension control is extremely important, in order to avoid such problems, motivated tight winding equipped digital constant tension yarn feeding device. The forming yarn density of the inside and outside layer completely consistent, to avoid due to the uneven density / unwinding tension fluctuation caused by the broken yarn parking and high speed winding rigid involved yarn stem strength and formation of hairiness or bonding imperfections, thus loom can effectively improve the weaving speed. Especially important is that with the loom weft storage device in yarn winding can achieve high speed yarn storage, the fabric directly after the realization of the weaving process consistency of density, enhance the fabric of quality and improve the weaving production efficiency.

Production Data:
Production comparison: as 40S yarn and other winding machine, under efficiency 85%

Actual production test data show that the improvement of the efficiency of self production, output is higher than that of the 127%, which is higher than that of the traditional 1332 type 47%, which can be optimized to reduce the number of spindles. It can directly reduce the workload in the winding process; including the operator and the amount of labor employment and porter.

Sunking Rewinding machine advantage:
To sum up, the economic and the high performance of the winding is summarized as below

- Reduction of product plant logistics and storage;

Weaving Process
- Weaving consumption reduced

- production raised
The high degree of density reduces the rate of broken yarn caused by the tension fluctuation, thereby reducing the rate of parking caused by the broken yarn, and directly improves the production efficiency of the weaving process.

- Weaving production development
Yarn density uniformity, in the weaving yarn by full pipe to ATC unwinding tension had no obvious change, which can effectively avoid the winding due to twist stress release makes the yarn twist/cases in fabric appear yarn faults phenomenon, the fabric density consistent, improve product quality
