Description
TECHNICAL FIELD OF THE INVENTION
[0001] The present invention relates to a dyeing machine that
carries out a dyeing operation on fabric, and in particular to a
structure that allows a horizontal dyeing machine to reduce the
amount of dye liquid used so as to make fabric dyeing more economic
and more environment-friendly and also reduce damage of the fabric
caused by excessive tension generated during the dyeing
operation.
DESCRIPTION OF THE PRIOR ART
[0002] In a conventional up-inclined or down-inclined
conveyor-driven fabric dyeing machine, a machine body is arranged
in an inclined state where a front end is located higher while a
rear end is lower or in the form of a front-low-rear-high
arrangement. A liquid storage tank is mounted to a bottom of the
machine body at the rear end thereof to receive dye liquid that
falls down from a rear end of a dyeing tube in order to reduce the
amount of dye liquid used. The dyeing tube can be set horizontally
or in a condition of slight inclination in order to reduce a height
between a fabric guide roller and the conveyor, meaning to reduce a
distance between the fabric guide roller and the conveyor, in order
to reduce the tension and a pulling force applied to the fabric
during the dyeing operation.
SUMMARY OF THE INVENTION
[0003] The primary objective of the present invention is to provide
a dyeing machine, which could save a great amount of dye liquid
(and thus water) even with a machine body in a horizontal form in
order to reduce fabric dyeing cost and enhance environmental
protection, and also to reduce a height between a fabric guide
roller and a conveyor device to make the tension of the fabric
driven by the fabric guide roller and the conveyor device so as to
prevent organization and property of the fabric from being
damaged.
[0004] The feature of the present invention is that a fabric dyeing
machine comprises a machine body having a bottom to which a liquid
storage tank is mounted to at a suitable location and lower than
the bottom of the machine body. The liquid storage tank has a
volumetric capacity sufficient to accommodate all or most of dye
liquid that falls down and returns from a rear end of a dyeing tube
in order to greatly reduce the amount of the dye liquid used.
Further, alternatively or additionally, a heat exchanger or a
filter may be separately mounted in the liquid storage tank or both
the heat exchanger and the filter are mounted in the liquid storage
tank to carry out temperature raising/lowering and filtration of
the dye liquid. As such, the size and structure of the dyeing
machine are simplified.
[0005] One technical solution of the present invention is that a
machine body of a fabric dyeing machine is set in a horizontal
configuration and a liquid storage tank, which is lower than a
bottom of the machine body, is mounted to the bottom of the machine
body at a predetermined location, such as middle, front end, or
rear end, and the liquid storage tank is pre-set with a volumetric
capacity for receiving dye liquid that is sufficient to accommodate
all or most of the dye liquid that falls down and returns from the
dyeing tube back into the machine body during an operation of the
dyeing machine such that the machine body contains therein a minor
portion, or even none, of the dye liquid during the operation
thereof. A pipe, a pump, and a heat exchanger that is arranged
externally of the machine body are connected between a bottom of
the liquid storage tank and a nozzle that is arranged inside the
machine body. The dye liquid is driven by the pump from the liquid
storage tank to pass through the heat exchanger that is outside the
machine body to supply to and jet from the nozzle, and the dye
liquid returns from the rear end of the dyeing tube to directly
fall into the liquid storage tank to thereby form a circulation of
the dye liquid.
[0006] The present invention allows a heat exchanger that is
externally of the machine body to be arranged inside the liquid
storage tank and also to arranged a filter in the liquid storage
tank to filter off chips and minute pieces of cotton and impurities
from the dye liquid in order to simplify the structure of the
dyeing machine and to further reduce the amount of water (liquid)
used.
[0007] The present invention alternatively allows a heat exchanger
or a filter to be individually arranged in the liquid storage
tank.
[0008] 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.

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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0013] 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.
[0014] In a first embodiment shown in FIG. 1, the present invention
provides a conveyor-driven horizontal fabric dyeing machine, which
comprises a machine body 1 that is set in a horizontal
configuration. A dyeing tube 12 is arranged, horizontally or
inclined, above the machine body 1 to allow fabric to move
therethrough. A conveyor device 2 is arranged below the dyeing tube
12. The machine body 1 is provided, in an interior space thereof,
with a nozzle 5 and a fabric guide roller 4 arranged at an upper
portion of a front end thereof. The machine body 1 is provided with
a liquid storage tank 6 that is mounted to a bottom thereof around
a middle portion. The liquid storage tank 6 extends downward from
the bottom of the machine body to a predetermined depth and the
liquid storage tank 6 is preset with a volumetric capacity
sufficient to accommodate all or most of the amount of dye liquid L
used in the machine body 1. The liquid storage tank 6 has a bottom
that is connected through piping to the nozzle 5, and a pump 7 and
a heat exchanger 8 that is arranged externally of the machine body
are mounted to the piping. The pump 7 is also connected through
piping to a chemicals barrel 11. Control of a dyeing treatment
process (which may be abbreviated as "dyeing process") and control
of the dyeing machine are achieved with a computer or a
programmable logic control (PLC) of a control box 9.
[0015] In the embodiment illustrated in FIG. 1, the fabric 3, after
being placed into the machine body 1, is driven, in the machine
body 1, by the fabric guide roller 4 to move into the nozzle 5, and
then enter the dyeing tube 12 to subsequently fall down back to the
conveyor device 2 to be conveyed for cyclic circulation. During the
course of cyclic circulation of the fabric 3, the pump 7 drives dye
liquid L accumulated in the liquid storage tank 6 and the machine
body of the dyeing machine to move through the heat exchanger 8 and
then jet from the nozzle 5 to assist moving of the fabric 3. The
dye liquid L interacts with the fabric 3 in both the nozzle 5 and
the dyeing tube 12 for dyeing. The dye liquid L that falls down
from a rear end of the dyeing tube 12 returns down to the bottom of
the machine body such that all or most of the dye liquid L flows
into and returns to the liquid storage tank 6 to accumulate
therein. Since a horizontal area of the liquid storage tank 6 is
smaller than that of the bottom of the machine body of the dyeing
machine, the liquid level can be increased for the same amount of
liquid in order to prevent excessive evacuation or vacuuming caused
by the pump 7, and on the other hand, the same liquid level can be
kept in the liquid storage tank 6 with a reduced amount of liquid
so that the amount of the dye liquid L used can be reduced.
Further, by arranging the liquid storage tank 6 as a structure
internally of the machine body 1, the entire structure of the
dyeing machine is simplified.
[0016] In addition to the structure described above, FIG. 1 also
shows an additional heat exchanger 8 may be arranged inside the
liquid storage tank 6, and also, a filter 61 may be mounted inside
the liquid storage tank 6 to remove chips or minute pieces of
cotton or fiber detached entraining or mixed in the dye liquid. As
such, the amount of the dye liquid L used can be further reduced
and the entire structure of the fabric dyeing machine can be
further simplified.
[0017] A second embodiment is shown in FIG. 2 and has a structural
arrangement similar to that of the first embodiment; however, the
liquid storage tank 6 is mounted to the bottom of the machine body
1 at a rear end thereof and the same effect and result as those
described previously can be achieved.
[0018] A third embodiment is shown in FIG. 3 and has a structural
arrangement similar to that of the first embodiment; however, the
liquid storage tank 6 is mounted to the bottom of the machine body
1 at a front end thereof and the same effect and result as those
described previously can be achieved.
[0019] 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.
[0020] 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.
