or below a nozzle, the dyeing tube comprising a fabric and liquid
entrance opening and a fabric and liquid exit opening, the dyeing
tube having an intermediate section that is set lower than the
fabric and liquid entrance opening and the fabric and liquid exit
opening so that the dyeing tube is configured to include height
differences that allows dye liquid to fill up an interior space of
the dyeing tube and remain in the dyeing tube, wherein during a
course of fabric moving through the dyeing tube, the fabric is
allowed to stay and soak in the dye liquid within the dyeing tube
to provide a sufficient period of time of interaction between the
fabric and the dye liquid remaining in the dyeing tube and thus an
extended period of time of penetration is realized to enhance the
result of dyeing, wherein the dyeing tube has a configuration that
provides the height differences at front and rear ends thereof.
Description
TECHNICAL FIELD OF THE INVENTION
[0001] The present invention relates generally to an improved
dyeing tube structure of a conveyor driven fabric dyeing machine,
and more particularly to a structure that allows dye liquid to
effectively fill and retain in the dyeing tube and causes fabric to
stay in the dyeing tube for an extended period of time and thus
extends exchange and penetration time between the fabric and the
dye liquid to thereby enhance uniformity of dyeing.
DESCRIPTION OF THE PRIOR ART
[0002] A conventional conveyor driven dyeing machine is structured
such that a dyeing tube is set above or under a machine body in a
horizontal or slightly inclined manner and a nozzle jets out the
dye liquid to flow through the dyeing tube. Fabric is moved within
the machine body and passes through the dyeing tube to be soaked in
the dye liquid for achieving circulation dyeing. However, since the
dyeing tube is arranged horizontally or in a manner of being
slightly inclined, the dye liquid, once entering the dyeing tube
through a liquid entrance opening, flows quickly through the dyeing
tube and then leaves from a dye liquid exit opening. In addition,
generally, the dyeing tube is not completely filled up with the dye
liquid so that the fabric and the dye liquid are allowed to
exchange and penetrate with each other in a short period of time.
As such, dyeing uniformity of the fabric is generally poor.
SUMMARY OF THE INVENTION
[0003] An objective of the present invention is to provide a
modified dyeing tube structure of a dyeing machine to allow dye
liquid to completely fill the dyeing tube and stay in the dyeing
tube for an extended period of time so that fabric that passes
through the dyeing tube is allowed to stay therein for an extended
period of time for exchange and penetration of dye liquid and thus
achieving an effect of more uniformly dyeing.
[0004] To overcome such a problem, the present invention provides a
conveyor driven fabric dyeing machine that comprises a dyeing tube
arranged rearward of or below a nozzle. The dyeing tube comprises a
fabric and liquid entrance opening and a fabric and liquid exit
opening, and the fabric and liquid entrance opening is set at a
location higher than the fabric and liquid exit opening. The dyeing
tube has an intermediate section that is set lower than the fabric
the liquid entrance opening and the fabric the liquid exit opening,
so that dye liquid may flow through the fabric and liquid entrance
opening into the dyeing tube and get retained in the dyeing tube
due to a height difference between the intermediate section of the
dyeing tube and each of the fabric and liquid entrance opening and
the fabric and liquid exit opening. This allows fabric, which moves
through the dyeing tube, to stay and soak in the dye liquid for an
extended period of time for penetration of the liquid into the
fabric thereby enhance the result of dyeing of the fabric. The
dyeing tube of the present invention may be shaped in any desired
configuration provided the height differences are present at the
front and rear ends thereof.
[0005] The technical solution provided in this invention is made to
improve a structure of a dyeing tube of a dyeing machine such that
the dyeing tube comprises a fabric and liquid entrance opening and
a fabric and liquid exit opening and the fabric and liquid entrance
opening has a height that is higher than or corresponds to a height
of the fabric and liquid exit opening, while an intermediate
section of the dyeing tube is set lower than the fabric and liquid
entrance opening and the fabric and liquid exit opening to allow
the dye liquid to fill up the dyeing tube and remain in the dyeing
tube, whereby fabric, during a course thereof moving through the
dyeing tube, can stay and soak in the dye liquid inside the dyeing
tube for liquid penetration into the fabric to enhance the dyeing
result of the fabric. The dyeing tube may be shaped in any desired
configuration provided the height differences are present at the
front and rear ends thereof.
[0006] 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

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0010] 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.
[0011] In a first embodiment shown in FIG. 1, the present invention
provides an improved structure of a dyeing tube of a conveyor
driven fabric dyeing machine. A general structure of the dyeing
machine comprises a machine body 1 in which a conveyor 2 is
arranged for conveying fabric 3 from a rear part of the machine
body 1 to a front part thereof, where the fabric 3 is driven by
means of a fabric guide roller 4 and an idle roller 41 to get into
a nozzle 5 and the dyeing tube 12. Dye liquid L is pressurized by a
pump 7 and subjected to temperature control by a heat exchanger 8
to be jetted by the nozzle 5 to drive the fabric 3 to enter the
dyeing tube 12 to achieve an effect of dyeing, through interaction
with, the fabric 3 that is then allowed to fall down, at the rear
part of the machine body, back onto the conveyor 2 to be
re-conveyed to the front part of the machine body, while the dye
liquid L also falls down back to a bottom of the machine body to
enter and accumulate in a liquid accumulation tank 6 and get
filtered by a filter 61 for removal of impurity and subsequent
pressurization by the pump 7 and temperature control by the heat
exchanger 8 to be re jetted by the nozzle 5 so as to achieve a
cyclic circulating motion to thereby realize the process of dyeing.
A control box 9 that comprises a computer or a programmable logic
controller (PLC) is operable to control or correct moving speeds of
the conveyor 2 and the fabric guide roller 4 in order to achieve
operation synchronization between the fabric 3 and the conveyor
2/the fabric guide roller 4 through accurately controlling the
speeds thereof.
[0012] In the embodiment shown in FIG. 1, the dyeing tube 12 is
structured to have a fabric and liquid entrance opening 121 (or an
entrance section) that is arranged vertically in the dyeing machine
and the nozzle 5 is set to jet the dye liquid into the fabric and
liquid entrance opening 121 in a direction from top to bottom. The
fabric and liquid entrance opening 121 of the dyeing tube 12 is set
at a height that is higher than a height of a fabric and liquid
exit opening 122 (or an exit section) and an intermediate section
of the dyeing tube 12, which is between the entrance opening and
the exit opening, is set lower than the fabric and liquid entrance
opening 121 and the fabric and liquid exit opening 122, so that a
first height difference d1 is present between the fabric and liquid
entrance opening 121 and the dyeing tube 12 (or more precisely, the
intermediate section of the dyeing tube). The height of the fabric
and liquid exit opening 122 is set higher than a height of an
interior top of the dyeing tube 12 so that a second height
difference d2 is present between the height of the fabric and
liquid exit opening 122 and the interior top of the dyeing tube 12.
As such, based on the communicating vessel principle, an interior
space of the dyeing tube 12 can be filled up with and hold the dye
liquid therein so that during the course of moving through the
dyeing tube 12, the fabric 3 may stay and soak in the dye liquid
inside the dyeing tube 12 for an extended period of time to allow
for an extended period of time of interaction between the fabric 3
and the dye liquid for better penetration that provides the fabric
3 with bettered and uniform result of dyeing. The dyeing tube 12
can be structured in any desired shape provided height differences
of the front and rear ends thereof are present. Further, due to a
dye bath body being of various different forms, the fabric and
liquid entrance opening 121 may be set at a height that is lower
than the fabric and liquid exit opening 122.
[0013] A second embodiment is shown in FIG. 2. The second
embodiment provides a dyeing machine having a structure generally
identical to that of the first embodiment with differences
therebetween concerning the directions in which the dyeing tube 12
and the nozzle 5 are arranged. Thus, certain description of the
structure of the dyeing machine of the second embodiment will be
omitted, due to similarity thereof with the first embodiment, and a
detailed description will be only given to the dyeing tube 12 of
the second embodiment. In the embodiment of FIG. 2, the fabric and
liquid entrance opening 121 (or entrance section) of the dyeing
tube 12 is set horizontally or slightly inclined to joint to the
dyeing machine, and the dye liquid is jetted by the nozzle 5 to
enter through the fabric and liquid entrance opening 121. The
fabric and liquid entrance opening 121 of the dyeing tube 12 is set
at a height that is higher than a height of a fabric and liquid
exit opening 122 (or exit section) so that a first height
difference d1 is present between the fabric and liquid entrance
opening 121 and the dyeing tube 12. The height of the fabric and
liquid exit opening 122 is set higher than a height of an interior
top of the dyeing tube 12 so that a second height difference d2 is
present between the fabric and liquid exit opening 122 and the
interior top of the dyeing tube 12. Thus, based on the
communicating vessel principle, an interior space of the dyeing
tube 12 that is below the fabric and liquid exit opening 122 may
hold and retain the dye liquid therein so that during the course of
moving through the dyeing tube 12, the fabric 3 may stay and soak
in the dye liquid inside the dyeing tube 12 for an extended period
of time to allow for an extended period of time of interaction
between the fabric and the dye liquid for better penetration that
provides the fabric 3 with bettered and uniform result of dyeing.
With different variation of the configuration of the dyeing bath
body, the fabric and liquid exit opening 122 may be set higher than
the fabric and liquid entrance opening 121.
[0014] 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.
[0015] 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.
