Open Width Fabric Stenter Machine Full Converter Controlled With Strong Rail

Open width Stenter Finishing Machine , full converter controlled , strong rail

1. Applications and machine features:

The VK-NB twin air channel type VK-NB stretch heat setting stenter finishing machine designed by VIROCK is suitable for all kinds of textile fabric finishing, especially for elastic fabric and sensitive fabric. This machine has high efficiency, low energy consumption, independent uniform temperature box design, and gives the fabric low tension. The equipment is versatile and can be used for all woven fabrics, knitted fabrics and warp knitted fabrics of natural and man-made fibres. The machine sets the speed of knitted fabrics 5-100 m / min and the speed of woven fabrics 7. 5-150 m / min. Suitable for dehydration, finishing, drying, baking and heat setting of knitted and woven fabrics. Its main features are as follows:

Entry-Frame:

Entry frame: 4.5m high, to be formed by 4mm thick steel plate, guider rollers, tightening rollers, infrared expanding and centering device are included.

Padder Mangle:

Mechanical parts for obtaining the rotation and the movement of the rollers made with cylindrical and     shifting supports.

Squeezing force obtained with extensible pneumatic hoods: Max. Pressure Kg. 10.000

Motorization at variable speed, made with motor and gearbox, directly coupled.

Chemical trough with chemical level control device of 150 lit.

1 Screw Roll f 125 mm

3 Guide Rolls f 125 mm

Edges Cutting Device:

Under guide cloth wheel and cutter can inside and outside synchronously move. When cutting cloth edge can control size. Easy to adjust and operate.

Double filters:

Each chamber has double filters; it’s easier for machine maintenance.

One layer of stainless steel filter screen removable design .It can be extracted to the outside cleaning cotton without open the oven door when the machine is running.

Air Blower:

Circulation air blower use centrifugal fan. The advantage is low noise and strong wind.

Overfeed/Underfeed pinning device:

Touch screen with human interface and PLC control. The Overfeed/Underfeed system is synchronized with the stenter chain at the accurate ratio read. (arrangement ratio:-20%,+50%)

Weft Straightener:

Weft straightening rolls by push-button control for correction rectilinear skew wefts with driven. Skew roll with synchronous transmission. The stretch fabric to achieve a very low tension.

Chain rails :

Chain rails made of special wear-resistant steel , high temperature resistance and transformed-free.
