Description

    Technical Field
  • 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
  • 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.
  • 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 types of dyeing machine allow more tension acting on fabric and the length of the machine allows sufficient time and space for the dyeing process inside the conveyance tube.
  • 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 by stainless steel plate. The stainless steel plate is highly surface finishing and contains plenty of sieves. The sieves can increase the draining rate of the dyeing solution to prevent the generation of turbulence. However, the increase of liquor-ratio and loading drop becomes the disadvantages.
  • Patent specification JP H08 325921 A discloses an air flow processing apparatus for fabric treatment, which carries out dyeing and other treatments.
  • Patent specification EP 1 972 712 A1 discloses a jet fabric dyeing machine.
    • Disclosure of the invention
  • 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.
  • It is an object of the invention to provide a dying machine which includes a conveyance tube. The exit of the conveyance tube is connected to a 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.
  • Furthermore, the said third section is made up by rods paralleled to the direction of fabric movement.
  • Furthermore, the rods mentioned in the final section of the fabric storage trough are covered by Teflon material.
  • Furthermore, the said third section is made up by smooth plates, the said plates are covered by Teflon material.
  • Furthermore, the storage trough has 5 to 35 degrees of the diagonal arrangement.
  • The full name of Teflon is Polytetrafluoroetylene, and its abbreviation is 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 unsmooth materials.
  • Furthermore, the mentioned curved plate in the first section of the fabric storage trough extends a section to the bottom of the second section.
  • The rods as described in the 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 an 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.
  • 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 arrives at the exit of the conveyance tube, dyeing solution provided a momentum to the fabric going from upstream to downstream. A large amount of dyeing solution will be drained away through the incision while the remaining solution keeps flowing on the extended part, thus it generates a differential forward speed to the fabric.

  • 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.
  • 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 an 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.
  • 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.
  • Fabric 1 first travels along the conveyance tube 3 to the first inlet 5 entering the 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 of 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 prevents clogging of fabric 1 in the second section. When the fabric 1 passes through the third section 7, the fabric 1 will re-enter the spraying nozzle 2 completing a cycle.
  • 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 is separated from fabric 1 and fabric 1 will then be stacked in an organized manner before re-entering spraying nozzle 2.
  • It should be noted that this invention patent will not be bounded by the above content description including schematics in terms of structural dimensions, shapes and use of materials.
