Description

Technical Field

[0001] This invention relates to the field of fiber dyeing technology, specifically a method for dyeing loose-fiber fibers. Background Technology

[0002] Fibers are substances composed of continuous or discontinuous filaments, widely used in textiles, military, environmental protection, medicine, construction, biology, and many other fields. Fibers are broadly classified into natural fibers and chemical fibers. Natural fibers exist naturally and are further divided into plant fibers, animal fibers, and mineral fibers; while chemical fibers are produced through chemical processing and can be divided into man-made fibers, synthetic fibers, and inorganic fibers. Fiber dyeing involves using dyes to color the fibers.

[0003] Loose fibers are lightweight and small in size, so spray-dyeing methods often result in significant missed spots. Furthermore, their light weight makes them prone to clustering on the dye bath surface when using immersion-based dyeing methods, leading to poorer dyeing quality and difficulty in removing them from the dyeing chamber. Therefore, we propose a new method for dyeing loose fibers. Summary of the Invention

[0004] The purpose of this invention is to provide a method for dyeing loose fibers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a method for dyeing loose-fiber fibers, the method comprising the following steps:

[0006] a. Feeding of loose fibers: The loose fibers are screened to remove impurities, and then piled up at the initial position of the conveyor belt.

[0007] b. Loose fiber conveying: The loose fibers piled at the initial position of the conveyor belt move along the direction of the conveyor belt. The conveyor side guards on both sides and the protective baffle at the end make it difficult for the loose fibers to be lost. The loose fibers are sucked into the dyeing chamber by the built-in fan in the conveying pipe.

[0008] c. Dyeing: The dyeing chamber is filled with an appropriate amount of dye liquor. Loose fibers fall into the dyeing chamber from the outlet of the feed pipe and come into contact with the dye liquor for dyeing. The bottom of the dyeing chamber is equipped with a stirring main shaft, stirring shaft groove and stirring rod body. The rotation of the stirring main shaft causes the stirring shaft groove and the stirring rod body in the unfolded state to rotate. The stirring shaft groove and stirring rod body can stir the dye liquor in the dyeing chamber, making the dye liquor into a vortex. The loose fibers fall into the vortex of dye liquor and mix quickly.

[0009] d. Dehydration: The perforated filter plate at the bottom of the dyeing chamber can move longitudinally under the drive of the longitudinal screw. By the rise of the perforated filter plate, the loose fibers scattered in various positions in the dyeing chamber and dyed can be lifted upward, thereby realizing the separation of loose fibers from dye.

[0010] e. Drying: After the perforated filter plate is raised to the drying chamber at the top of the dyeing chamber, the loose fibers are quickly dehydrated and dried using a built-in fan on the conveyor shaft.

[0011] f. Discharge: Place the loose fiber collection bag on the opening of the drive main disc, and then reverse the built-in fan of the conveyor shaft disc to allow the dried loose fibers to enter the collection bag from the drive main disc to complete the discharge.

[0012] Preferably, in step b, conveyor side guards are provided on both sides of the upper part of the conveyor belt, and the side of the conveyor side guards is connected to the support part of the conveyor belt through support rods. One end of the conveyor belt is the feeding end and the other end is the discharging end. A protective baffle is provided at the end of the discharging end, and the two ends of the protective baffle are connected to the side wall of the conveyor side guard.

[0013] Preferably, the conveying pipe extends through the opening of the dyeing chamber into the cavity of the dyeing chamber, and the other end of the conveying pipe extends above the discharge end of the conveying side guard plate. The fan built into the conveying pipe transmits the loose fibers from the discharge end of the conveying side guard plate into the cavity of the dyeing chamber through the conveying pipe.

[0014] Preferably, in step c, the dyeing chamber and the drying box adopt a segmented design. The stirring main shaft is located at the lower center of the dyeing chamber cavity. The stirring shaft grooves are distributed in a circular array on the annular outer wall of the stirring main shaft. Each set of stirring shaft grooves is equipped with a set of stirring rod connecting shafts. The stirring rod connecting shafts connect to set a set of stirring rod bodies in each set of grooves. The stirring rod bodies are perpendicular to the grooves of the stirring shaft grooves. The two ends of the stirring rod connecting shafts are rotatably connected to the inner wall of the stirring shaft grooves. Torsion springs are set at both ends of the stirring rod connecting shafts. The width of the stirring rod body matches the depth of the stirring shaft groove.

[0015] Preferably, the stirring main shaft passes through the bottom wall of the dyeing chamber and is connected to the stirring connecting shaft, and a linkage vertical shaft is provided on one side of the stirring connecting shaft. The bottom outer wall of the dyeing chamber is fixed with a drive main motor, and the output end of the drive main motor is connected to the linkage vertical shaft. A synchronous conveyor belt is connected between the linkage vertical shaft and the stirring connecting shaft to make the linkage vertical shaft and the stirring connecting shaft rotate synchronously.

[0016] Preferably, a horizontal gear disc is sleeved on the outer side of the lower half of the linkage vertical shaft, and an active gear disc is provided on one side of the horizontal gear disc. A lead screw is fixed in the center of the active gear disc, and a drive gear disc is engaged above the lead screw. A second drive main disc is fixed in the center of the drive gear disc, and a second conveyor shaft is connected to the end rotating shaft of the conveyor belt.

[0017] Preferably, a driven disc is provided between the conveyor shaft disc and the drive main disc, and a lifting rod is connected to the shaft center of the driven disc. A rod pressure rod is fixed to the top of the lifting rod, and a pressure rod slot is provided on the surface of the dyeing chamber to allow the linkage shaft to move longitudinally.

[0018] Preferably, in step d, the dyeing chamber has a perforated filter plate and a closed bottom plate at the top and bottom, respectively. The center of both the perforated filter plate and the closed bottom plate is provided with a plate opening larger than the stirring spindle. The connecting surfaces of the closed bottom plate and the perforated filter plate are connected at intervals by several sets of brackets. A longitudinal lead screw is provided on the inner wall of the dyeing chamber, and a lead screw motor for driving the longitudinal lead screw to rotate is provided at the top of the longitudinal lead screw. A longitudinal limiting rod is provided on the other side of the inner wall of the dyeing chamber. The surfaces of the closed bottom plate and the perforated filter plate are provided with threaded holes that mesh with the longitudinal lead screw and round holes that pass through the longitudinal limiting rod.

[0019] Preferably, in step e, the inner wall of the drying box is fixed with a sealing baffle by a support rod. When the perforated filter plate moves to the top, the sealing baffle is inserted into the cavity of the opening in the plate. The conveyor shaft is fixed to the top of the drying box by bolts. The drying box is fitted on the top of the dyeing chamber. The discharge pipe is fitted on the top of the conveyor shaft. The drive main plate is connected to the conveyor shaft and the dyeing chamber. A fan is installed inside the discharge pipe.

[0020] Preferably, a functional cylinder is fixed to the bottom of the closed base plate by a vertical rod, and an insert block is slidably sleeved at the opening of the functional cylinder, and a secondary spring is provided inside the cavity of the functional cylinder to abut against the surface of the insert block.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] This invention features a set of stirring shafts driven by a main motor within the dyeing chamber. The surface of the stirring shafts is circumferentially distributed with several sets of stirring shaft grooves and vertically distributed stirring rods within these grooves. When the stirring shafts rotate, the grooves and extended stirring rods rotate and stir the dye within the dyeing chamber, allowing loose fibers to sink quickly. This improves the dyeing efficiency of the loose fibers, enabling them to integrate more rapidly into the dyeing process. Furthermore, driven by the lead screw motor and the longitudinal lead screw, the perforated filter plate and the closed bottom of the perforated filter plate... The bottom plate can move upwards, using a perforated filter plate to lift the loose fibers and remove them from the dyeing water surface, achieving efficient separation of loose fibers and dye. As the bottom plate and perforated filter plate rise, the screw motor can also use the power of the screw motor to lift the upright pressure bar upwards within the slot of the pressure bar using insert blocks. This compresses the spring at the top of the slot of the pressure bar, causing the driven disc to separate from the conveyor shaft disc and the drive main disc. This stops the rotation of the conveyor belt, allowing the loose fibers to temporarily remain on the conveyor belt to avoid affecting subsequent dyeing and dehydration, thus improving the overall dyeing quality and efficiency of the loose fibers.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-10 The present invention provides a technical solution: a method for dyeing loose fibers, the method comprising the following steps:

[0036] a. Feeding of loose fibers: The loose fibers are screened to remove impurities, and then the loose fibers are piled up at the initial position of conveyor belt 4.

[0037] b. Loose fiber conveying: The loose fibers piled at the initial position of the conveyor belt 4 move along the direction of the conveyor belt 4. The conveyor side guards 5 on both sides and the protective baffle 6 at the end make it difficult for the loose fibers to be lost. The loose fibers are sucked into the dyeing chamber 1 through the built-in fan of the conveying pipe 3.

[0038] c. Dyeing: The dyeing chamber 1 is filled with an appropriate amount of dye liquor. Loose fibers fall into the dyeing chamber 1 from the outlet of the feed pipe 3 and come into contact with the dye liquor for dyeing. The bottom of the dyeing chamber 1 is equipped with a stirring main shaft 17, a stirring shaft groove 18 and a stirring rod body 20. The rotation of the stirring main shaft 17 causes the stirring shaft groove 18 and the stirring rod body 20 in the unfolded state to rotate. The stirring shaft groove 18 and the stirring rod body 20 can stir the dye liquor in the dyeing chamber 1, making the dye liquor into a vortex. The loose fibers fall into the vortex of dye liquor and mix quickly.

[0039] d. Dehydration: The perforated filter plate 24 at the bottom of the dyeing chamber 1 can move longitudinally under the drive of the longitudinal screw 21. By the rise of the perforated filter plate 24, the loose fibers scattered in various positions in the dyeing chamber 1 and dyed can be lifted upward, thereby realizing the separation of loose fibers from dye.

[0040] e. Drying: After the perforated filter plate 24 is lifted into the drying chamber 2 at the top of the dyeing chamber 1, the loose fibers are quickly dehydrated and dried by the built-in fan of the conveyor shaft disc 71.

[0041] f. Discharge: Place the loose fiber collection bag over the discharge pipe 38, and then reverse the fan 28 built into the conveyor shaft disc 71 so that the dried loose fibers enter the collection bag through the discharge pipe 38 to complete the discharge.

[0042] In step b, conveyor side guard plates 5 are provided on both sides of the upper part of the conveyor belt 4, and the sides of the conveyor side guard plates 5 are connected to the support part of the conveyor belt 4 through support rods. One end of the conveyor belt 4 is the feeding end, and the other end is the discharging end. A protective baffle 6 is provided at the end of the discharging end, and both ends of the protective baffle 6 are connected to the side wall of the conveyor side guard plate 5. The loose fiber limiter moves from the feeding end to the discharging end as the conveyor belt 4 rotates. The two sides are limited by the obstruction of the conveyor side guard plates 5. The discharging end is blocked by the protective baffle 6 to prevent loose fibers from falling off from above the conveyor belt 4. The conveying pipe 3 The feed pipe 3 extends through the opening in the dyeing chamber 1 into the cavity of the dyeing chamber 1. The other end of the feed pipe 3 extends above the discharge end of the conveying side guard plate 5. The blower built into the feed pipe 3 transmits the loose fibers from the discharge end of the conveying side guard plate 5 into the cavity of the dyeing chamber 1 through the feed pipe 3. The opening of the feed pipe 3 extending into the cavity of the dyeing chamber 1 faces downward, which facilitates the loose fibers to fall quickly into the dye liquor in the dyeing chamber 1. The top of the dyeing chamber 1 is provided with an opening for feeding dye, and the bottom side is provided with a discharge port. The discharge port is sealed with a cover. After the cover is opened, the slag removal work in the cavity of the dyeing chamber 1 can be carried out.

[0043] In step c, the dyeing chamber 1 and the drying chamber 2 adopt a segmented design. The stirring main shaft 17 is located at the lower center of the dyeing chamber 1. The stirring shaft grooves 18 are arranged in a circumferential array on the annular outer wall of the stirring main shaft 17. Each set of stirring shaft grooves 18 is equipped with a set of stirring rod connecting shafts 19, and a set of stirring rod bodies 20 is set in each set of grooves through the connection of the stirring rod connecting shafts 19. The stirring rod bodies 20 are perpendicular to the grooves of the stirring shaft grooves 18. The two ends of the stirring rod connecting shafts 19 are rotatably connected to the inner wall of the stirring shaft grooves 18, and torsion springs are set at both ends of the stirring rod connecting shafts 19. The width of the stirring rod bodies 20 matches the depth of the stirring shaft grooves 18. The stirring main shaft 17 passes through the bottom wall of the dyeing chamber 1 and is connected to the stirring connecting shaft 16. A linkage vertical shaft 13 is set on one side of the stirring connecting shaft 16. The bottom outer wall is fixed with a drive motor 14, and the output end of the drive motor 14 is connected to the linkage vertical shaft 13. A synchronous conveyor belt 15 is connected between the linkage vertical shaft 13 and the stirring connecting shaft 16 to make the linkage vertical shaft 13 and the stirring connecting shaft 16 rotate synchronously. The stirring shaft groove 18 is arc-shaped, so the dyeing in the dyeing chamber 1 can be stirred when the stirring shaft groove 18 rotates. In order to enhance the stirring effect, the stirring rod body 20 vertically in the stirring shaft groove 18 also rotates. Therefore, the combination of the stirring rod body 20 and the stirring shaft groove 18 makes the dyeing liquid in the dyeing chamber 1 form a vortex, so that the loose fibers can be incorporated into the dyeing chamber 1 more quickly. Due to the action of the torsion springs at both ends of the stirring rod connecting shaft 19, each set of stirring rod bodies 20 can be pushed longitudinally and then pulled into the groove of the stirring shaft groove 18.

[0044] In step d, the dyeing chamber 1 has a perforated filter plate 24 and a closed bottom plate 26 at the top and bottom, respectively. Both the perforated filter plate 24 and the closed bottom plate 26 have openings 25 at their centers, larger than the stirring shaft 17. The connecting surfaces of the closed bottom plate 26 and the perforated filter plate 24 are connected at intervals by several sets of brackets. A longitudinal lead screw 21 is installed on the inner wall of the dyeing chamber 1, and a lead screw motor 22 is installed at the top of the longitudinal lead screw 21 to drive its rotation. A longitudinal limiting rod 23 is installed on the other side of the inner wall of the dyeing chamber 1. The surfaces of the closed bottom plate 26 and the perforated filter plate 24 have threaded holes 33 that mesh with the longitudinal lead screw 21 and circular holes that pass through the longitudinal limiting rod 23. After the lead screw motor 22 starts, it drives the longitudinal lead screw 21 to rotate. The meshing connection between the threaded holes 33 and the longitudinal lead screw 21 allows the perforated filter plate 24 and the closed bottom plate 26 to move longitudinally within the dyeing chamber 1. Meanwhile, to improve the stability of the movement of the perforated filter plate 24 and the closed bottom plate 26, the presence of the round hole and the longitudinal limiting rod 23 keeps the perforated filter plate 24 and the closed bottom plate 26 stable. The plate opening 25 in the center of the perforated filter plate 24 and the closed bottom plate 26 can be moved around the outside of the stirring shaft 17. When the perforated filter plate 24 moves upward, it can push the unfolded stirring rod body 20 into the groove of the stirring shaft groove 18, so that the top of the perforated filter plate 24 is at the top opening of the dyeing chamber 1. The top opening of the dyeing chamber 1 is covered by the drying box 2, and a set of sealing baffles 37 connected by a bracket is fixed on the inner wall of the drying box 2. The sealing baffles 37 match the opening of the plate opening 25. In this way, the separation of loose fibers and dye is completed by the lifting of the perforated filter plate 24. At the same time, the drain outlet 27 on the surface of the closed bottom plate 26 is used for the dye to flow into the dyeing chamber 1.

[0045] A horizontal gear disc 12 is sleeved on the outer side of the lower half of the linkage vertical shaft 13, and an active gear disc 11 is provided on one side of the horizontal gear disc 12. A lead screw 10 is fixed in the center of the active gear disc 11, and a drive gear disc 9 meshes above the lead screw 10. A drive main disc 82 is fixed in the center of the drive gear disc 9. The end rotating shaft of the conveyor belt 4 is connected to a transmission shaft disc 72. A driven disc 29 is provided between the transmission shaft disc 72 and the drive main disc 82, and a lifting rod 30 is connected to the shaft center of the driven disc 29. A rod pressure rod 31 is fixed in the top of the lifting rod 30. The surface of the dyeing chamber 1 is provided with a permissible opening. The pressure rod slot 32 of the vertical shaft 13 moves longitudinally. The bottom of the closed base plate 26 is fixed with a functional cylinder 34 by a vertical rod. An insert block 36 is slidably sleeved at the opening of the functional cylinder 34. A secondary spring 35 is provided inside the cavity of the functional cylinder 34 to abut against the surface of the insert block 36. As the closed base plate 26 moves upward, the functional cylinder 34 connected to the bottom of the closed base plate 26 by the vertical rod moves upward. The secondary spring 35 inside the functional cylinder 34 provides a forward elastic force to the insert block 36. During the movement of the closed base plate 26, it is in close contact with the inner wall of the dyeing chamber 1. Finally, the insert block 36 extends into the pressure rod slot 32. The spring at the top of the spring-lifting rod 30 groove is compressed, causing the lead screw 10 to separate from the middle position of the transmission shaft disk 72 and the drive main disk 82. This prevents the rotational power of the drive gear disk 9 from outputting power to the transmission shaft disk 72, stopping its rotation. Consequently, the loose fibers above the conveyor belt 4 stop moving, preventing the loose fibers from entering the dyeing chamber 1 when the perforated filter plate 24 moves to the top of the dyeing chamber 1. When the perforated filter plate 24 descends, the insert... As block 36 descends, the spring inside the slot 32 of the pressure rod presses down, causing the driven disc 29 at the bottom of the lifting rod 30 to press tightly against the conveyor shaft disc 72 and the drive main disc 82. After the drive main motor 14 starts, the linkage shaft 13 and the horizontal gear disc 12 rotate synchronously. At the same time, the synchronous conveyor belt 15 completes the synchronous movement of the stirring connecting shaft 16 and the linkage shaft 13. The horizontal gear disc 12 meshes with the drive gear disc 11, so that the rotation of the horizontal gear disc 12 can drive the rotation of the drive gear disc 11. The rotation of the drive gear disc 11 drives the lead screw 10 to rotate, and the rotation of the lead screw 10 drives the drive gear disc 9 to rotate.

[0046] In step e, the inner wall of the drying chamber 2 is fixed with a sealing baffle 37 by a support rod. When the perforated filter plate 24 moves to the top, the sealing baffle 37 is inserted into the cavity of the plate opening 25. The conveyor shaft plate 7 is fixed to the top of the drying chamber 2 by bolts. The drying chamber 2 is fitted on the top of the dyeing chamber 1. The drive main plate 81 is fitted on the top of the conveyor shaft plate 71. The drive main plate 81 is connected to the conveyor shaft plate 71 and the dyeing chamber 1. After the perforated filter plate 24 is raised to the top, the fan 28 built into the discharge port 38 is started, so that the external airflow is drawn into the cavity of the drying chamber 2 to dry the loose fibers placed above the perforated filter plate 24. After the fan 28 rotates in the opposite direction, a collection bag can be fitted at the discharge port 38 to collect the loose fibers.
