Description
TECHNICAL FIELD OF THE INVENTION
[0001] The present invention relates to a conveyor-driven
dual-nozzle fabric dyeing machine, and in particular to a dyeing
machine that is equipped with a conveyor device and includes two
dyeing tubes each of which is connected to a respective nozzle,
such that to dye fabric, the fabric could be conducted to move
through suitable one of the nozzles and the dyeing tube associated
therewith according to the property of the fabric to be dyed in
order to acquire an optimum effect of dyeing.
DESCRIPTION OF THE PRIOR ART
[0002] To have fabrics of different kinds, such as knitting, plain
weaving, and fibrous fabrics, better dyed, dyeing machines are
generally designed so that a nozzle is located below or behind a
fabric guide roller and is arranged horizontally or inclined with a
dyeing tube. As such, relative positions between the nozzle and the
fabric guide roller are different, leading to contact surface
between fabric and the fabric guide roller having different arcs
during the circulation of the fabric. Different contact surfaces
and different angles of the nozzle would cause different effects on
the fabric, such as slippery rate, tension, and folding marks. To
suit different needs of different fabrics, different designs of
dyeing machine are available.
SUMMARY OF THE INVENTION
[0003] The primary objective of the present invention is to provide
a useful conveyor-driven dyeing machine, which suits for dyeing
fabrics of different kinds in order to the simplified models of
dyeing machines.
[0004] The features of the present invention is such that the
dyeing machine comprises a machine body having an interior space in
which a conveyor device for conveying fabric and a fabric guide
roller are arranged; a first dyeing tube and a second dyeing tube
through which the fabric selectively passes for being dyed; a first
nozzle that is located below the fabric guide roller and is
connected to the first dyeing tube; and a second nozzle that is set
horizontally or in an inclined condition and is connected to the
second dyeing tube. To dye fabric, according to the kind of fabric
to be dyed, the fabric, after guided around the fabric guide
roller, is selectively fed through the first nozzle into the first
dyeing tube for being dyed or is alternatively fed through the
second nozzle into the second dyeing tube and also a rear portion
of the first dyeing tube to be dyed therein. The fabric, after
passing through the first dyeing tube, falls down onto the conveyor
device so that the conveyor device conveys the fabric forward to
pass around the fabric guide roller and move through the first
dyeing tube or the second dyeing tube again for circulation to
proceed with the dyeing operation, whereby the circulation speed of
the fabric is made fast, the uniformity of dyeing is made better,
the tension of the fabric is reduced, folding marking on the fabric
is avoided, and thus an optimum effect of dyeing can be
achieved.
[0005] One technical solution of the present invention comprises a
machine body, in which a conveyor device, a fabric guide roller, a
first dyeing tube, and a second dyeing tube are arranged. The first
dyeing tube has a front end connected to a first nozzle that is
located below the fabric guide roller. The second dyeing tube has a
front end that is connected to a second nozzle that is set in a
horizontal position, and the second dyeing tube has a rear end
connected to the first dyeing tube at a location between the front
and rear ends thereof.
[0006] Another technical solution of the present invention is that
the second dyeing tube is set inclined at an angle relative to the
first dyeing tube so that the front end of the second dyeing tube
is higher than the first nozzle.
[0007] The foregoing objectives and summary provide only a brief
introduction to the present invention. To fully appreciate these
and other objects of the present invention as well as the invention
itself, all of which will become apparent to those skilled in the
art, the following detailed description of the invention and the
claims should be read in conjunction with the accompanying
drawings. Throughout the specification and drawings identical
reference numerals refer to identical or similar parts.
[0008] Many other advantages and features of the present invention

invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0011] The following descriptions are exemplary embodiments only,
and are not intended to limit the scope, applicability or
configuration of the invention in any way. Rather, the following
description provides a convenient illustration for implementing
exemplary embodiments of the invention. Various changes to the
described embodiments may be made in the function and arrangement
of the elements described without departing from the scope of the
invention as set forth in the appended claims.
[0012] As shown in FIG. 1, a dyeing machine according to a
preferred embodiment of the present invention comprises a machine
body 1 that is provided on an upper part thereof with a first
dyeing tube 15 that is arranged in a horizontal or slightly
inclined condition to receive fabric 3 to pass therethrough. The
first dyeing tube 15 has a front end that is connected to a nozzle
5A that is set at a location below a fabric guide roller 4, while
the fabric guide roller 4 is arranged at a location that is even
higher. The machine body 1 has an interior space in which a
conveyor device 2 is arranged. The machine body 1 is provided, at a
location behind the fabric guide roller 4, with a second dyeing
tube 16 that is inclined with respect to the first dyeing tube 15
at a predetermined angle. The second dyeing tube 16 has a front end
that is provided with a second nozzle 5B, such that the second
nozzle 5B can be set horizontally or in the same direction of the
second dyeing tube 16. The second dyeing tube 16 has an opposite
rear end that is connected to and in communication with a portion
of the first dyeing tube 15 between the front end and a rear end
thereof. At a location between the rear end of the second dyeing
tube 16 and a rear end of the first dyeing tube 15, a fabric
leading edge detector 10 arranged in the first dyeing tube 15.
[0013] At a rear end of the machine body 1, which may be inclined
downward, a liquid storage tank 6 is arranged. Preferably, the
liquid storage tank 6 is provided therein with a filter 61. The
liquid storage tank 6 has a bottom that is connected through piping
to the first nozzle 5A and the second nozzle 5B, wherein the piping
is provided with a pump 7 and a heat exchanger 8 mounted thereto.
The pump 7 is also connected through piping to a chemicals barrel
11. A first control valve 13 is mounted between the heat exchanger
8 and the first nozzle 5A and a second control valve 14 is mounted
between the heat exchanger 8 and the second nozzle 5B.
[0014] To carry out a dyeing operation, the fabric 3 is positioned
in the machine body 1 for cyclic circulation in order to be dyed,
wherein, based on the kind of fabric to be dyed, the fabric 3 is
guided around the fabric guide roller 4 to pass through the first
nozzle 5A that is located below the fabric guide roller 4 and the
first dyeing tube 15 (as shown in FIG. 1) so as to have the fabric
3 dyed. The fabric 3 so dyed is moved through the rear end of the
first dyeing tube 15 to fall down to the conveyor device 2 to be
cyclically conveyed to the front end, where the fabric passes the
fabric guide roller 4 once again to repeat the above-described
process for dyeing.
[0015] Alternatively, based on the kind of fabric to be dyed, the
fabric 3 may be guided around the fabric guide roller 4 to pass
through the second nozzle 5B, which is at a higher location and may
be set in a horizontal or slightly inclined condition, and the
second dyeing tube 16 (as shown in FIG. 2), so as to have the
fabric 3 dyed. The fabric 3 so dyed moves to pass through the rear
end of the second dyeing tube 16 and enter the first dyeing tube 15
for further dyeing. After passing through the rear end of the first
dyeing tube 15, the fabric 3 will similarly fall down to the
conveyor device 2 to be cyclically conveyed to the front end, where
the fabric passes the fabric guide roller 4 once again to repeat
the above-described process for dyeing.
[0016] The pump 7 drives dye liquid L accumulated in the liquid
storage tank 6 to move through the heat exchanger 8 to subsequently
jet from the first nozzle 5A or the second nozzle 5B to assist
moving the fabric 3 for circulation and dyeing. The dye liquid L
interacts with the fabric 3 for dyeing in the first nozzle 5A and
the first dyeing tube 15 or in the second nozzle 5B and the second
dyeing tube 16. The dye liquid L that moves to the rear end of the
first dyeing tube 15 and falls down therefrom to a bottom of the
machine body 1, where all or most of the dye liquid L will fall
into and return to the liquid storage tank 6 to be further pumped
by the pump 7 to pass through the heat exchanger 8 and then jetted
through the first nozzle 5A or the second nozzle 5B to further move
through the first dyeing tube 15 again and returns back to the
machine body 1 to complete a cycle of circulation.
[0017] Chips or minute pieces of cotton or fiber detached from the
fabric 3 during conveyance and dyeing would be filtered off by the
filter 61 when the dye liquid L is pumped out of the liquid storage
tank 6.
[0018] Operation speeds of the fabric guide roller 4 and the
conveyor device 2 and opening/closing of the first control valve 13
and the second control valve 14 are controlled by a control box 9
to be in synchronization with a circulation speed of the fabric 3.
These speeds can be adjusted, or they can be set at constant values
or fixed values after being properly managed, meaning the
circulation speed of the fabric 3 can be made constant and thus,
the circulation time of each cycle of circulation is constant. The
dyeing treatment process (which may be abbreviated as "dyeing
process") could be controlled by using "time" as a control unit in
a way that is similar to the prior art dyeing machine, or could be
alternatively controlled by using the number of cycles of
circulation of the fabric through the dyeing machine as detected by
the fabric detector 10. The control is carried out with a computer
or a programmable logic control (PLC) of the control box 9 or other
electro-mechanical device based controllers to proceed with the
dyeing process.
[0019] In brief, the present invention provides a dyeing machine
that is provided with a conveyor device 2 and further includes a
first dyeing tube 15 and a second dyeing tube 16 mounted thereto
such that the first and second dyeing tubes 15, 16 are respectively
connected to a first nozzle 5A and a second nozzle 5B, wherein to
dye fabric, based on the property of the fabric to be dyed, the
fabric may be selectively moved through the first nozzle 5A and the
first dyeing tube 15 or the fabric may be selectively and
alternatively moved through the second nozzle 5B and the second
dyeing tube 16 to acquire an optimum effect of dyeing.
[0020] It will be understood that each of the elements described
above, or two or more together may also find a useful application
in other types of methods differing from the type described
above.
[0021] While certain novel features of this invention have been
shown and described and are pointed out in the annexed claim, it is
not intended to be limited to the details above, since it will be
understood that various omissions, modifications, substitutions and
changes in the forms and details of the device illustrated and in
its operation can be made by those skilled in the art without
departing in any way from the claims of the present invention.
