Description
TECHNICAL FIELD OF THE INVENTION
[0001] The present invention relates to a saturated extreme low
liquor ratio conveyor-driving atmospheric fabric dyeing machine,
and more particularly to a fabric dyeing machine that makes use of
a mechanical force (a conveyor device), as a substitute of
hydraulic buoyance force that is traditionally used, to drive
fabric for circulation in order to carry out atmospheric dyeing of
the fabric in a rectangular or non-circular machine shape body.
DESCRIPTION OF THE PRIOR ART
[0002] A known high-temperature conveyor-driving dyeing machine has
a machine body that is a pressure vessel. To accommodate the
internal environment of the machine body that is generally of a
high pressure and a high temperature, the machine body must be
designed as a cylindrical vessel and thus, the interior of the
machine body is correspondingly cylindrical. However, such a
cylindrical internal space often suffers being hard for
optimization due to constraints on installation of related
peripheral equipment, components, or devices caused by the machine
body space, and provides a relatively small effective space for
accommodating fabric, leading to small capacity of fabric dyeing
and being hard to an operator to do maintenance and service.
Consequentially, the known cylindrical body of a fabric dyeing
machine is inherently involved with certain shortcomings.
[0003] Further, in the known fabric dyeing machine, a plaiting down
device that is used to arrange the fabric cannot be optimized in
respect of adjustment of swing angle and amplitude due to
constraints caused by the shape of the machine body, and
consequentially, a fabric guide device that is used to guide the
fabric cannot be optimized in respect of adjustment of guiding
angle, so as to result in undesired limitation of
functionality.
[0004] Further, in the known fabric dyeing machine, a conveyor
device installed inside the machine body is arranged, together with
a dyeing tank of the machine body, parallel to the dyeing tank. In
an attempt to be re-set as in an inclination angle, a main body of
the dyeing tank of the machine body has to be made inclined.
However, since the relative position among related components
inside the dyeing tank is not changed, the performance of the
dyeing tank of the machine body may not be optimized in respect of
change of types of fabric or its loading capacity.
SUMMARY OF THE INVENTION
[0005] The primary objective of the present invention is to provide
a technical solution that allows full use of an internal space of a
rectangular machine body of a dyeing machine so as to allow for
optimization of arrangement of a main body of a dyeing tank and an
internal structure thereof to thereby enhance the performance of
the dyeing machine, allowing an increase of the capacity of fabric
that can be loaded in the dyeing tank of the dyeing machine and
allowing an operator to carry out maintenance and servicing
operations in an easier way.
[0006] Another objective of the present invention is to provide a
fabric dyeing machine that selection can be made between a single
nozzle solution or a dual nozzle solution to proceed with
jet-dyeing of fabric inside a dyeing tube and driving of the fabric
to move according to the type, structure, and amount of the fabric
conveyed therein.
[0007] A further objective of the present invention is to provide a
fabric dyeing machine that allows adjustment of oscillation angle
and amplitude of a fabric plaiting down device and also allows
adjustment of a fabric guiding angle of a fabric guide device.
[0008] Yet a further objective of the present invention is to
provide a fabric dyeing machine that allows adjustment of an
inclination angle of a front end, or a rear end, or both of a
conveyor device installed in an interior of a machine body.
[0009] The present invention provides a low-temperature fabric
dyeing machine operated in a temperature lower than 110.degree. C.,
including a conveyor device for driving. The machine body has an
interior space in which the conveyor device is installed. The
interior space of the machine body has a lateral cross-section that
is rectangular in shape or is similar to a rectangular shape, so as
to allow a dyeing tank of the interior of the machine body to
receive an increased capacity of fabric. A dyeing tube is equipped
above the machine body and is connected to a front end and a rear
end of the machine body. A first nozzle is equipped at a front end
of the dyeing tube, and a second nozzle is installed at a rear end
or a suitable location of the dyeing tube. A fabric plaiting down
device is installed in the interior space of the machine body and
at a rear end of the dyeing tank. Disposed below and corresponding
to the location of the fabric plaiting down device is a fabric
guide device. The conveyor device is installed along a length and a
width of the machine body and is provided, at a length of a front
end or a rear end or both thereof, with an inclination adjusting
section having a slope that is adjustable. A spraying device is
installed at a suitable location in the interior of the machine
body to wash and clean the interior of the spraying device and to
wet the fabric in dyeing. A water storage tank is designed at a
bottom of the machine body and includes, in an interior thereof,
built-in heat exchanger and filter net. The built-in heat exchanger
has an outer casing that is connected by a pipeline to a pump, and
the pump is connected by a first and a second connection tubes to
the first nozzle and the second nozzle in order to convey the dye
liquid that is recovered from a bottom of the dyeing tank to the
nozzles.
[0010] Preferably, the fabric plaiting down device is adjustable in
respect of angle and amplitude of oscillation in a left-right
direction in order to accommodate different kinds of fabric for
more orderly depositing the fabric on the conveyor to increase the
loading capacity of fabric to be dyed.
[0011] Preferably, the fabric guide device is movable for varying a
position thereof in a front-rear direction and is adjustable for an
incline angle thereof in order to adjust a slope for guiding the
fabric to responsively guide different types of fabric to smoothly
move onto the conveyor.
[0012] Preferably, the spraying device comprises a water supply
tube, and the water supply tube is constructed with a plurality of
spraying holes, so that water spraying from each of the spraying
holes to wash and clean the interior of the machine body and to wet
the fabric in dyeing.
[0013] Based on the above-described structural arrangement of the
saturated extreme low liquor ratio conveyor-driving atmospheric
fabric dyeing machine, the present invention provides the following
advantages:
[0014] (1) In a dyeing process of fabric, no soaking in dye liquid
of a high liquid level is necessary, and absorption of liquid to a
saturation condition would be sufficient, such that compared to the
prior art soaking dyeing machine, the consumption of water, steam,
electricity, and some chemicals can be greatly reduced and
consequently, waste water and emission of CO.sub.2 can be greatly
reduced to completely resolve the issues of environmental
protection.
[0015] (2) The interior space of a machine body of the dyeing
machine can be full and effectively used to make the performance
and structure of the dyeing machine optimized, so as to increase
the capacity of fabric that can be accommodated in a dyeing tank of
the machine body and to allow an operator to easily carry out
operations of maintenance and servicing for the interior of the
machine body.
[0016] (3) Selection can be made between one single nozzle or two
nozzles according to the property of the fabric or the thickness of
the fabric in order to inject dye liquid inside the dyeing tube and
to drive the fabric to move to thereby enhance an effect of uniform
dyeing.
[0017] (4) The fabric plaiting down device is adjustable in respect
of the oscillation angle and amplitude in a left-right direction
and the fabric guide device is movable for shifting of position
thereof in a front-rear direction and is adjustable for an angle
the fabric guide device to adjust a slope of guiding the fabric so
as to responsively guide fabric of different types and different
capacity to orderly deposit on and enter a conveyor to thereby make
operation smooth and increase the capacity of fabric to be
dyed.
[0018] (5) The conveyor device installed in the interior of the
machine body is adjustable in respect of an inclination angle of a
front end, or a rear end, or both thereof in order to make
conveyance of fabric of different types and different amounts
smoother and also to reduce a distance from a fabric driving reel
to the conveyor to reduce the tension of the fabric.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0023] As shown in FIGS. 1-4, the present invention provides a
saturated extreme low liquor ratio conveyor-driving atmospheric
fabric dyeing machine, which comprises a dyeing tube 12, which is
arranged above a machine body 1 to allow fabric to pass
therethrough and which is designed in a horizontal condition or a
slightly inclined condition. A fabric driving reel 4 is arranged
at, and set at a position higher than, a front end of the machine
body 1. A first nozzle 5 is arranged at a front end of the dyeing
tube 12. A second nozzle 13 and a fabric plaiting down device 8 are
arranged at a rear end of the dyeing tube 12. The fabric plaiting
down device 8 is adjustable in respect of an oscillation angle and
an oscillation amplitude in a left-right direction, so that the
fabric, upon falling after coining out from the rear end of the
dyeing tube 12, is subject to oscillation of the fabric plaiting
down device 8 to fall, in an alternating and orderly manner, down
onto the fabric guide device 9 that is located at a lower side
thereof. The fabric guide device 9 comprises a curved or arc
surface or an inclined surface and is adjustable in respect of
location and angle thereof in a front-rear direction in order to
responsively accommodate the fabric in dyeing that falls down from
the fabric plaiting down device 8 for directing and guiding the
fabric onto the conveyor device 2.
[0024] The machine body 1 is equipped, in an interior of a dyeing
tank thereof, with a conveyor device 2. The conveyor device 2 is
arranged along a length and a width of the machine body 1 and is
equipped, at a lengthwise position from a front end thereof, with a
sprocket 16 (or other mechanical components). A curvable or
bendable inclination adjusting section L is equipped between the
sprocket 16 (or other mechanical components) and a front end of the
conveyor device 2. The inclination adjusting section L is
adjustable in respect of an inclination angle thereof. Namely, when
the inclination angle of the inclination adjusting section L is
made larger, a distance between the front end of the conveyor
device 2 and the fabric driving reel 4 gets shorter, helping reduce
the tension induced in the self-weight of fabric and also helping
prevent from or eliminate the rearward fabrics incline and overlap
toward the frontward fabrics when the fabric leaves from the
conveyor device 2. Preferably, a rear end of the conveyor device 2
also adopts the same arrangement as the front end thereof, so as to
smooth the falling of the fabric through the fabric plaiting down
device 8 down onto the conveyor device 2 to prevent or alleviate
the fabric inclining or overlapping frontward. The fabric, as being
conveyed by the conveyor device 2, is driven to the front end to be
pulled upward by the fabric driving reel 4 for feeding into the
nozzle to thereby complete circulation of the movement thereof.
[0025] A spraying device 10 is provided in an interior of the
machine body 1 and is set at an upper side at a proper location.
The spraying device 10 is designed with a plurality of spraying
holes 11 arranged along a length thereof. The spraying device 10
can be directly connected to a water inlet pipe or can be extended
to an output portion of a pump, so that upon supply of water or
upon opening of a valve during operation of the pump, water or
dyeing liquid may be sprayed upward, or downward, or toward all
sides from the spraying holes 11 in order to wash and clean the
interior of the machine body 1 and also to wet the fabric in
dyeing.
[0026] The present invention also equipped a water storage tank 6
arranged at a bottom of the machine body 1 to include therein a
built-in combination of a heat exchanger and filter net 6A. The
water storage tank 6 is connected through a pipeline to a pump 7,
and the pump 7 is connected by a first connection tube 3 to the
first nozzle 5 and is connected by a second connection tube 3A to
the second nozzle 13. Impurity contained in the dye liquid inside
the machine body 1 is subject to filtering by the filter net, and
the dye liquid enters the built-in combination of heat exchanger
and filter net 6A to subject to heat exchange for heating or
cooling. The dye liquid, after being subject to heat exchange and
filtering, is pumped by the pump 7 to supply to the first nozzle 5
and the second nozzle 13 for jetting therefrom to dye the fabric
inside the dyeing tube 12 and to drive the fabric to move through
the dyeing tube 12, and as such, the dye liquid can be repeatedly
recycled and cyclically used and conveyed.
[0027] An inlet port of the pump 7 is connected by a connection
tube to a chemicals tank 14, and when chemical agents or dyestuff
are supplied, the pump 7, during operation thereof, retrieves the
chemicals or dyestuff from the chemicals tank 14 to be mixed with
the dye liquid that is moved in the circulation thereof to be
supplied through the first connection tube 3 and the second
connection tube 3A to the first nozzle 5 and the second nozzle 13
for being mixed with the dye liquid inside the dyeing tube 12 to
proceed with dyeing on the fabric. In response to differences of
property and amount of fabric in different batches, the present
invention allows for selection of activation of just the first
nozzle 5 to jet the dye liquid, or simultaneous activation of both
the first nozzle 5 and the second nozzle 13 to jet the dye liquid
in order to achieve the best effect of jet-dyeing of the
fabric.
[0028] The present invention provides a saturated extreme low
liquor ratio conveyor-driving atmospheric fabric dyeing machine,
which could make a full use of the interior space of the machine
body of the dyeing machine to achieve arrangement and installation
of internal components or devices that are more appropriate and
more convenient to thereby optimize the performance and structure
of the dyeing machine and also to allow the dyeing tank of the
machine body to accommodate an increased loading capacity of fabric
and to ease operations of maintenance and service for an operator
and which also allows for selection between one single nozzle or
two nozzles for jetting dye liquid inside a dyeing tube to drive
the movement and dyeing of the fabric according to the property of
the fabric so as to enhance the effect of uniform dyeing and
alleviate the shortcoming of crease mark, and which is equipped
with a fabric plaiting down device that allows adjustment of an
oscillation angle and amplitude in a left-right direction and a
fabric guide device that allows shifting of position in a
front-rear direction and adjustment of an incline angle for guiding
fabric so as to responsively guide fabric of different types to
smoothly and orderly enter a conveyor device, and also allows
adjustment of an inclination slope of each of two ends of the
conveyor device disposed in the interior of the machine so as to
responsively direct different batches of fabric in dyeing for
circulating and conveyance to thereby prevent or alleviate the
rearward fabrics incline and overlap toward the frontward fabrics.
Thus, the present invention is a low-temperature fabric dyeing
machine, operated in a temperature lower than 110.degree. C., which
involves great improvement.
