Technical Field
[0001] This invention patent involves a type of dyeing machine storage trough. It can effectively
enhance the looping efficiency of the fabric inside the machine. The looping efficiency
of the dyeing machine directly affects the fabric loading and liquor-ratio. Thus,
the invention of the storage trough is related to the technical field in dyeing industry.
Background of the Invention
[0002] The dyeing machine storage trough is the key for fabric or gray cloth to run smoothly
and stacked regularly. The movement of the stacked fabric is depended to gravitational
force, water flow and compression.
[0003] In the field of dyeing industry, L-shape or Longitudinal high temperature dyeing
machine are normally used to dye light and thin fabric, especially chemical fiber.
These type of dyeing machine allow more tension acting on fabric and the length of
the machine allow sufficient time and space for dyeing process inside the Conveyance
tube.
[0004] However, low looping efficiency becomes the main issue of using L-shape or Longitudinal
high temperature dyeing machine, as plaiting device is not included in the upstream
position. To solve the problem, the recent storage trough is designed as diagonal
arrangement instead of parallel to the ground. The gravitational force helps the fabric
moving from upstream to downstream. Low friction material, for example a row of Teflon
rods is placed in the bottom of the storage trough to smoothen the fabric motion,.
However, the light and thin fabric is easily spoiled by the turbulence. On the other
hand, the design is revised by replacing the Teflon rods to stainless steel plate.
The stainless steel plate is highly surface finishing and contain plenty sieves. Those
sieves can increase the draining rate of dyeing solution to prevent the generation
of turbulence. However, the increase of liquor-ratio and loading drop becomes the
disadvantages.
Disclosure of the invention
[0005] It is an object of the invention to improve the recent dyeing machine storage trough.
The invention improves the handling on light and thin fabric especially chemical fiber,
increase the looping efficiency and loadings and, lower the liquor-ratio.
[0006] It is an object of invention to include a conveyance tube. The exit of the conveyance
tube is connected to the storage trough. The storage trough is designed to have a
diagonal arrangement. Also, the storage trough is divided into three sections. The
first section is a curved plate, which is impermeable and with a smooth surface. The
second section is a plate with sieves and the final third section is a row of low
friction part.
[0007] Furthermore, the said third section is made up by robs paralleled to the direction
of fabric movement.
[0008] Furthermore, the rods mentioned in the final section of the fabric storage trough
are covered by Teflon material.
[0009] Furthermore, the said third section is made up by smooth plates, the said plates
are covered by Teflon material.
[0010] Furthermore, the storage trough has 5 to 35 degrees of the diagonal arrangement.
[0011] The full name of Teflon is Polytetrafluoroetylene, and its abbreviation Teflon, PTFE,
F4 etc. Teflon is a unique of fluoro coating with high-performance such as good heat
resistance, chemical inertness, Insulation stability and low friction and its basic
part is polytef.
the surface of the second section sieve is not smooth, for example, some un-smooth
materials.
[0012] Furthermore, the mentioned curved plate in first section of the fabric storage trough
extend a section to the bottom of second section.
[0013] The rods as described in third section are covered by a layer of Teflon material.
[0014] The first section has an extended part to the second section. The extended part occupies
1/3 of the second section. Also, there is incision on two sides of the extended part.
The lengths of the first and second section are equal. The length of third section
is larger than the sum of the first and second section.
[0015] The purpose of dividing the storage trough into three sections is to produce overfeed
phenomenon. This phenomenon helps the fabric move smoothly from upstream to downstream,
and avoids the scratching. When fabric arrive the exit of the conveyance tube, dyeing
solution provided a momentum to the fabric going from upstream to downstream. Large
amount of dyeing solution will be drain away through the incision while the remained
solution keep flowing on the extended part, thus it generate a differential forward
speed to the fabric.

Embodiments of the Invention
[0017] As shown in figure 1-2, It is an object of invention to include a conveyance tube.
The exit of the conveyance tube is connected to the storage trough. The storage trough
is designed to have a diagonal arrangement. Also, the storage trough is divided into
three sections. The first section is a curved plate, which is impermeable and with
a smooth surface. The second section is a plate with sieves and the third section
is a row of low friction rods parallel to the trough.
[0018] Furthermore, the storage trough has 5 to 35 degrees of the diagonal arrangement.
The rods as described in third section are covered by a layer of Teflon material.
The first section has an extended part to the second section. The extended part occupies
1/3 of the second section. Also, there is incision on two sides of the extended part.
The lengths of the first and second section are equal. The length of third section
is larger than the sum of the first and second section.
[0019] A Loop of fabric passes through the conveyance tube by the dyeing solution. The fabric
is propelled by the high speed dyeing solution from the nozzle, to the exit of the
conveyance tube. The exit of the conveyance tube is bended and tangential to the storage
trough. Thus, the fabric can smoothly pass through conveyance tube and storage trough.
The entrance of the storage trough is considered as the first section, with the help
of low friction impermeable curved plate.
[0020] Fabric 1 first travel along conveyance tube 3 from the first inlet 5 entering storage
trough 8. Dyeing solution ejected from nozzle 4 propels fabric 1 to the first stage
of storage trough 5 onto a smooth, low friction and impermeable curved plate, fabric
1 is then smoothly carried to the second stage of storage trough 6. When fabric 1
passes through the second stage of storage trough 6, dyeing solution will be drained
from the bottom sieve plate and enters a relatively high friction section, slowing
the speed down. Due to speed difference between the first and second section, fabric
1 will be over fed in the second section, stacking in an organized manner. Stacked
fabric 1 will be pushed into the third section 7 of the storage trough, travelling
on top a series of low friction tubular bars, aligned parallel to the direction of
fabric travel. Because the friction in the third section is low, this prevented clogging
of fabric 1 in the second section. When the fabric 1 passes through the third section
7, the fabric 1 will re-enter spraying nozzle 2 completing a cycle.
[0021] The storage trough described in this invention is installed with Teflon bars at the
bottom, aligned parallel to the travel direction of fabric 1, combing with the tilted
trough design, the fabric 1 will naturally fall under gravity. To reduce liquor ratio,
the dyeing fluid cycling time needs to be shortened. To prevent interference between
fluid from nozzle and fabric 1 at the lower stream of the conveyance tube, a section
design approach is taken. By using different design inside the conveyance tube, dyeing
fluid be separated from fabric 1 and fabric 1 will then be stacked in an organized
manner before re-entering spraying nozzle 2.

of materials. Designs with same, similar or improved working principle including change
