Description
BACKGROUND OF THE INVENTION
[0001] (a) Technical Field of the Invention
[0002] The present invention is generally related to fabric dyeing
machines, and more particular to an air-flow dyeing machine capable
of preventing fabrics from having creases during the dyeing
process.
[0003] (b) Description of the Prior Art
[0004] A conventional air-flow dyeing machine contains components
such as nozzle, dyeing channel, guiding pulley, blower, dye pump,
heat exchanger, filter, etc. A fabric is placed inside the machine
body. The blower pressurizes the air inside the machine into jet
steam so as to drive the fabric to move. The dyeing channel
provides a passage for the fabric to cycle through so that the
fabric is contracted and sprayed with dyes. The guiding pulley
helps the fabric to cycle inside the machine body. The dye pump
pressurized the dyes into the heat exchanger to heat up or cool
down. The dyes are then atomized by mixing with the jet stream, and
sprayed by the nozzle on the fabric.
[0005] Compared to liquid-flow dyeing machines which drive the
fabric to cycle by dyeing agent and guiding pulley, air-flow dyeing
machines drive the fabric to cycle by air and guiding pulley. The
former has a larger dye pump whereas the latter has an additional
blower. The air-flow dyeing machines have the advantages of
significantly reduced water usage and therefore agent usage.
[0006] However, the air-flow dyeing machines require high-volume
and high-pressure air-flow, and the blower therefore consumes much
more power than the power consumed by the liquid-flow dyeing
machines' agent pump. As such, despite the reduced water usage,
air-flow dyeing machines fail to achieve true environmental
friendliness and recued production cost. In addition, to facilitate
fabric's cycling, the air-flow dyeing machine bodies are usually
designed to have a U-like, circular, or short tubular shape. The
fabric therefore is often compressed together and creases are
produced.
SUMMARY OF THE INVENTION
[0007] A major objective of the present invention is to provide an
air-flow dyeing machine which, in addition to having a transmission
device to move the fabric, utilizes a blower to produce
high-pressure jet steam to mix and atomize dyes pumped to a nozzle
so that the atomized dyes can easily permeate into a fabric runs
through the nozzle. The jet steam also helps moving the fabric
through a dying channel. The fabric then falls on a transmission
device to cycle the fabric through the dyeing process. The air-flow
dyeing machine provides significantly reduced consumption of water
and power. The fabric cycled by the transmission device is
prevented from having creases due to compression during the dyeing
process. The production quantity and efficiency are both
enhanced.
[0008] The air-flow dyeing machine comprises a machine body, a
blower, a pump, and a heat exchanger. The machine body comprises a
nozzle, a dyeing channel, a post guiding device, and a transmission
device. The nozzle is connected to the blower via a high-pressure
tube so that a high-pressure jet steam is delivered to the nozzle.
The jet steam mixes with and atomizes dyes delivered to the nozzle
by the pump. The atomized dyes are sprayed on the fabric running
through the nozzle. The jet steam helps moving the fabric through
the dyeing channel, and the fabric then falls on the transmission
device and cycles back to the dyeing channel. The machine body has
a long tubular shape so that the fabric is prevented from
compression and as such creases.
[0009] Preferably, the transmission device is configured inside the
machine body, and there can be one or more transmission devices.
The transmission device moves the fabric to cycle through the
nozzle and the dyeing channel. The power of the jet stream can be
effectively reduced as well. In other words, using both the
transmission device and the high-pressure air-flow as driving
source has more environmental friendliness, enhanced production,
and reduced cost.
[0010] Furthermore, using transmission device to move the fabric
prevents the fabric from compression and creases.
[0011] 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.
[0012] Many other advantages and features of the present invention
will become manifest to those versed in the art upon making
reference to the detailed description and the accompanying sheets
of drawings in which a preferred structural embodiment
incorporating the principles of the present invention is shown by
way of illustrative example.
BRIEF DESCRIPTION ION OF THE DRAWINGS
[0013] FIG. 1 is a schematic diagram showing an air-flow dyeing
machine according to an embodiment of the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0014] 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.
[0015] As illustrated in FIG. 1, an air-flow dyeing machine
according to an embodiment of the present invention contains a
machine body 1, a blower 6, a pump 7, a heat exchanger 8, a control
box 9, and an agent barrel 11. Inside the machine body 1, there is
a dyeing channel 12 in an upper portion and a transmission device 2
in a bottom portion. A fabric 3 to be dyed runs through the dyeing
channel 12 and over the transmission device 2. Also in the top
portion inside the machine body 1, there are a guiding pulley 4, an
idle pulley 41, and a nozzle 5. The nozzle 5 is piped to the heat
exchanger 8 and the pump 7. The pump 7 is also piped to the agent
barrel 11. The nozzle 5 is also connected to the blower 6 via a
high-pressure tube 61. A fabric examination device 10 is configured
in an appropriate place inside the machine body 1, and a
post-guiding device 13 is configured adjacent to the transmission
device 2 so as to guide the fabric 3 after it runs through the
dyeing channel 12 onto the transmission device 2. The dyeing
process by the air-flow dyeing machine is controlled by the control
box 9. The transmission device 2, depending on requirement, can be
a belt-based, a roller-based, or a mesh-based transmission
device.
[0016] The fabric 3 inside the machine body 1 is delivered through
the nozzle 5 by the idle pulley 41 and the guiding pulley 4, and
then into the dyeing channel 12. The fabric 3 then falls on the
transmission device 2 through the post-guiding device 13 and enters
a cycling process. During the cycling process, the pump 7 forces
dyes and the agent in the agent barrel 11 out of the nozzle 5 after
they run through the heat exchanger 8. In the meantime, the blower
pressurizes outside air into a jet stream which is sent to the
nozzle 5 via the high-pressure tube 61. The dyes are then atomized
by the jet steam and sprayed onto the fabric 3 by the nozzle 5. The
jet steam also drives the fabric 3 to move. The fabric 3 is dyed
both in the nozzle 5 and in the dyeing channel 12. In addition, as
the fabric 3 runs through the dyeing channel 12, the fabric
examination device 10 can detect the fabric 3's cycle time, number
of cycles, and display, record, and output various information and
signals to the control box 9.
[0017] After going through the dyeing channel 12 and falling on the
transmission device 2, the fabric 3 is delivered by the
transmission device 2 back to the idle pulley 41 and the guiding
pulley 4, and re-enters the nozzle 5. The foregoing movement and
dyeing process is as such repeated.
[0018] The air-flow dyeing machine according to the present
invention has the following advantages.
[0019] First, the fabric inside the machine body is driven entirely
by high-pressure air-flow together with the transmission device
without using any water. Therefore, dyes and agents are
significantly saved, and power consumption and waste process cost
are highly reduced.
[0020] Second, the fabric is supported and moved on the
transmission device during the process and the fabric is cycled
steadily and smoothly. The fabric therefore is not scratched,
fluffed, or damaged. Furthermore, the fabric is free from problems
such as knots, tangles, and pressing.
[0021] Third, the machine body has a long tubular shape, and
fabrics can be uniformly arranged on the transmission device. The
production quantity is increased and the fabrics are free from
creases.
[0022] 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 spirit of the present invention.
