Winch Dyeing Machine:
Introduction:
The winch dyeing machine is mainly used for the winch dyeing of wool
fabric, silk fabric, cotton and its blended knitted fabric and chemical
fiber simulation fabric. Winch dyeing machine can also be used for
scouring and bleaching, soaping and washing of some silk fabrics,
cotton and its blended knitted fabrics. This is because these fabrics
tend to stretch, chafe and come apart. Dyeing machinery should meet
the special requirements of small tension and friction. At present, there
are various forms and varieties of this kind of machinery. In general,
there are normal temperature and pressure winch dyeing machine,
normal temperature and pressure overflow dyeing machine, high
temperature and pressure overflow machine, jet dyeing machine and
so on.
Winch dyeing machine can be divided into normal temperature and
pressure type and high temperature and pressure type. Normal
pressure winch dyeing machine is easy to use and is the most
commonly used dyeing equipment for cotton knitting.
WE-1 winch dyeing machine is a normal temperature and pressure
winch dyeing machine. It is designed for laboratory use of dyeing,
boiling off, bleach and washing, etc. processing for all kinds of
expensive natural fabric, and knitting fabric or woven fabric of blinding
under normal temperature & normal pressure, and also for the
application of dyeing and processing for rayon, polyacry-nitrile fiber,
and blended fabric under normal temperature & normal pressure.

Winch dyeing machine principle:
The fabric is connected from end to end and dipped in the dyeing tank in a
relaxed and bent shape，bypassed the cloth guide roller, basket roller lifts
it and then falls into the dyeing tank. The circulation runs to achieve the
purpose of dyeing the fabric. During dyeing, the fabric is immersed in the
dyeing tank in a relaxed state for most of the time, and the tension is small.
WE-1 winch dyeing machine operating state
Winch dyeing machine feature:
1. Whole machine material is high strength corrosion-resistance stainless steel;
2. High-performance drive system, and equipped with high step-less adjustable
motor to adapt to different material and processing capacity;
3. Heating method steam or electrical;
4. Equipped with movable front door, easy to operate;
5. Equipped with lighting device on the top of machine to observe inner
working situation of machine clearly;
6. Soft processing status to ensure that the material will not be harmed and will
not produce feather；
7. Reduce process time, improve production efficiency, dark fabric dyeing time
only 280 minutes;
8. Less water consumption, less discharge, less sewage treatment, less dyes
and chemical additives, and more environmental protection;
9. Power saving, the main pump motor adopts frequency converter soft start,
and the discharge can be carried out without shutdown.

Winch dyeing machine structure
Dye tank:
The dyeing tank is made of stainless steel. The inner wall of the dyeing tank and
its weld are polished and easy to clean. Strong perforated separators separate the
fabric from the heating tube. The front glass windows is solid durable tempered
glass, and easy to observe the inside of the fabric movement, the groove is
equipped with lighting device.The device is equipped with liquid level meter, which
is helpful to control liquid quantity, and thermometer for temperature control.
The tank also overflows water outlet and water valve and other devices.
Roller:
The basket roller, cloth guide roller and its shaft are all made of stainless steel.
The u-shaped section of its support tube can prevent the fabric from slipping. It is
conducive to uniform dyeing.
Heating system
Electric heating tube direct heating or steam heating.
Winch dyeing machine process:
Water inlet
1. Close the drainage valve.
2. Open the water inlet valve and close the water inlet valve when the water
reaches the required water level.
Feed in
1.Check whether the water level in the tank is the required water level.
2. Open the cloth guide roller.
3. Feed the end of the cloth to be dyed from the guide roller into the dye tank.
4. Hook the cloth head out of the cloth slot with a cloth hook and put it aside until it
is about 2 meters into the cloth.
5. Stop the guide roll. Connect the cloth end to end, and then open the cloth guide
roller to circulate the cloth.
Add dye chemicals and additives
Dyeing chemicals and additives according to process requirements.
Washing
1. Open the water inlet and drainage valves at the same time for circulating water
washing, and pay attention to the inflow and displacement must be consistent.
2. After washing, close the water inlet valve and open the drainage valve. After
finding the cloth head, close the cloth guide roller.
3. Untie the cloth head, pull it out and put it on the cloth-out roller. Open the out
cloth motor and cloth can be released.
Winch dyeing machine development
Since the 1960s, the new equipment types of winch dyeing machine are jet dyeing
machine, normal temperature overflow dyeing machine, airflow dyeing machine
and so on. Jet dyeing machine is an intermittent dyeing equipment with high effect,
which is suitable for dyeing synthetic fiber fabrics of many varieties and small
batches. It is mainly composed of dyeing tank, ejector, distributing tube, heat
exchanger and circulating pump.
When dyeing, the fabric is connected head to tail, and the fabric is lifted from the
dyeing bath by the cloth guide roller, which is driven by the liquid flow from the
ejector to advance in the cloth guide tube, and then falls into the dyeing tank and is
dipped in the dyeing bath in a relaxed bending shape and moves forward slowly,
and is lifted again by the cloth guide roller to run circularly. The dye is driven by a
high-power pump, through a heat exchanger, and then speeded up by an ejector.
