HY-7DV HIGH SPEED DRAW TEXTURING MACHINE
HY-7 model texturing machine adopts single -roller and single-motor direct driving system, and the fully-enclosed primary heater, including the features of simple structure, easy mainte- nance and energy-saving.
HY-7DV HY-7HLV and HY-7S are used for ply-yarns, de-torque yarns, also can produce S twist and Z twist yarn. For these two types, A and B side can be operated completely independently, enable to produce high quality, multi-type, multi-specification yarns to meet the requirement of a most dynam- ic market. HY-7DV HY-HLV is used for polyester yarn and HY-7S for polyamide yarns.
HY-7(LC) can produce polyester with Spandex covering yarn, expanding the machine usage.

1)Energy saving
Energy-Saving Heater. Use a new fully-enclosed primary heater and new structured secondary heater. Fully-enclosed heater can reduce the heat dissipation area.Impoved the inside structure by increasing the internal thermal insulation material, reduce the energy consumption.
Individual motorized Friction Unit(optional). Replaces the traditional tangential belt and tension wheel to save energy, reduce noise level and minimize maintenance costs.
Driving System. The system applies a single-shaft and single-motor direct driving method, each shaft is driven separately, controlled by respective inverters.The mechanical structure is more compact and simple. It removes the transmission links such as timing belts, tension pulleys, bearing blocks, etc. Improve transmis- sion efficiency, reduces energy consumption, simplifies design and saves on energy.
Godet feed unit. The Godet drafting device with single spindle-single motor driving, increase the yarn gripping force, make the drafting ratio more reliable, and improve the yarn quality. Removing the nip roller(or apron) these quick wear parts, easy for maintenance and lower the use cost; Single spindle-single motor driving, reduce the energy consumption of drafting roller drive chain system, save the energy.
2)High intelligence of electrical control system
We feature state of the art electronic controls and electrical drivers, which allow convenient machine adjustments and reliable operation of the machines. The motor drive controls involve closed loop control systems, consisting of PLC, inverter and photoelectric sensors. The rotational speed precision is highly accurate. The machine can be equipped with the latest advanced take up proces- sor to ensure a well formed package that unwinds equally well.The Online Tension System is optional, which can check&monitor the yarn tension T2 of each spindle, assuring the quality of the yarns.
3)High speed and high efficiency
Single-roller and Single-motor direct driving system. Both machine sides can be operated independently, which enables the simultaneous processing of two different yarn. All shafts are driven directly which eliminates the gear box and drive belts,lowers of noise level and allows high speed production and product quality.
Individual motorized Friction unit(optional). Simplify the machine structure and reduce the noise level and allow high process speeds.
Pneumatic threading device.The smooth threading speed can reduce the yarn breaking during string up as compared with the traditional manual threading device, ensures the quality of each yarn end , especially for fine denier yarn processes.
4)Easy operation and maintenance
Single-shaft and single-motor directly driving system abandons timing belts and tension pulleys, eliminates their normal replacement and maintenance, reduces maintenance time and costs, a further advance to the progressive develop- ment of maintenance-free condition.
Godet feed unit (Optional). Godet feed unit abandons apron or nip roller, reduces the maintenance and spare part cost.Meantime, the individual motor driven godet technology replacing the feed shafts in the texturing zone allows for consid- erably higher process speeds and less downtimes.
5)Nice texturing process quality
The driving system uses a single-shaft and single-motor direct driving method. W4, take up shafts are in single-independent transmission design, allowing a more flexible adjustment of winding tension, helpful to the improvement of package shape,parameters can be independently set for each deck the winding tension can be fine-tuned according to the actual situation which broadens the false-twist texturing process adjustment range.
Advanced take up processor. Advanced take up processor for better winding performance and yarm quality. Online tension system. Real-time monitoring of continuous tension on the thread; close monitoring of filament quality; and automatically grading the quality of the produced DTY.
Godet Feed unit(optional) The godet technology avoids yarn quality losses caused by apron or nip roller abrasion during the yarn texturing process, enables the production of yarns of the highest quality, especially suitable for fine denier yarns.
6)Modular and multifunctional features
With the growing demand for varieties of textile fabrics, all kinds of special fiber, special processing technology, the special style of yarn in order to meet the requirements of this yarn processing, the user can according to your needs, choose different configuration of various functional models,use the new processing method, the synthetic fiber has the properties of natural fibers.The selection of wire drawing device; The selection of auxiliary rollers in different positions; Spandex device selection and/so on all kinds of combination./The number of spinning varieties can be expanded by increasing the special equipment, and the conventional varieties can be produced by closing the equipment.Through flexible selection and configu- ration, different models are formed to meet the different characteristics of the production of differentiated fiber, to meet the user's pursuit of high value-added products.
Recommended plant conditions
In order to give the machine the best running cor nditions and to achieve optimum quality products, a DTY plant should have the following conditions:
1.Power: 380V±10%, three phase; 50Hz±1; good ground system (other voltage optional)
2.Compressed air:
