Description

Technical Field

[0001] This invention relates to the field of yarn dyeing technology, specifically to a method and apparatus for efficient and uniform yarn dyeing based on a hollowed-out flow guiding structure. Background Technology

[0002] Yarn dyeing is a process in which fibers such as cotton, polyester, and wool are spun into yarn and then dyed before weaving. The dyed yarn is then woven into fabric according to design requirements, forming complex patterns such as stripes, checks, and jacquards. It is widely used in yarn-dyed fabrics, sweaters, denim, and other products. Compared to dyeing greige fabric, yarn dyeing results in more durable colors, a more three-dimensional fabric style, and better adaptability to the fashion demands of small-batch, multi-variety production. In the yarn dyeing process, the yarn cones are usually assembled on a cone holder, which is then placed into a dyeing tank, where the dyeing tank performs the dyeing of the yarn cones. However, existing technologies still have some shortcomings when dyeing yarn cones: Currently, as the yarn packages enter the dyeing tank along with the yarn package frame, the yarn packages are stationary in the dyeing tank, making it difficult for the yarn on the yarn packages to fully contact the dyeing liquid in the dyeing tank, thus affecting the dyeing effect of the yarn packages. At the same time, after the yarn packages are placed on the insertion rods of the yarn package frame, it is necessary to limit the yarn packages at the upper end of each insertion rod. Since there are multiple insertion rods, the limiting of the yarn packages is relatively inconvenient and the labor intensity is high.

[0003] To address the aforementioned problems, the inventors have proposed a method and apparatus for efficient and uniform yarn dyeing based on a hollowed-out flow guiding structure. Summary of the Invention

First, install the yarn package to be dyed on the dyeing package frame, and then use an overhead crane to hoist the dyeing package frame into the dyeing vat. S2. Add a dispersant to the staining tank. The dispersant reacts with the staining solution to prevent the staining solution from agglomerating. S3. The honeycomb perforations on the dyeing bobbin rack form an interlaced flow path, causing the dyeing solution to flow turbulently between multiple yarn bobbins, thereby improving the penetration ability of the dyeing solution. S4. Control the dyeing parameters of the dyeing vat in stages to ensure uniform dyeing of the yarn on each yarn package.

[0006] Preferably, the staining parameters include a penetration stage, a fixation stage, and a rinsing stage.

[0025] 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.

[0026] Example: Figure 1-7 As shown, this invention provides a method for efficient and uniform dyeing of yarn based on a hollowed-out flow-guiding structure, comprising the following steps: S1. First, install the yarn package to be dyed on the dyeing package frame, and then use an overhead crane to hoist the dyeing package frame into the dyeing vat. S2. Add a dispersant to the staining tank. The dispersant reacts with the staining solution to prevent the staining solution from agglomerating. S3. The honeycomb perforations on the dyeing bobbin rack form an interlaced flow path, causing the dyeing solution to flow turbulently between multiple yarn bobbins, thereby improving the penetration ability of the dyeing solution. S4. Control the dyeing parameters of the dyeing vat in stages to ensure uniform dyeing of the yarn on each yarn package.

[0027] The staining parameters include the penetration stage, the fixation stage, and the rinsing stage. The temperature of the penetration stage is 40~45℃, the time is 6~8min, and the flow rate of the staining solution is 0.3~0.5m / s. The temperature of the fixation stage is 75~85℃, the time is 12~15min, and the flow rate of the staining solution is 0.4~0.5m / s. The temperature of the rinsing stage is 55~60℃, the time is 3~5min, and the flow rate of the staining solution is 0.8~1m / s.

[0028] This invention also provides an apparatus for a highly efficient and uniform yarn dyeing method based on a hollowed-out flow guiding structure, including a dyeing tank 1 and a yarn package frame 2. The yarn package frame 2 is disposed inside the dyeing tank 1 and includes a base 21. The upper end face of the base 21 is provided with an equipment disk 22. A fixed shaft 23 is provided at the axial center of the equipment disk 22. A plurality of insert rods 24 arranged in a ring array are fixedly disposed on the upper surface of the equipment disk 22. A plurality of flow guiding holes 25 are provided on the insert rods 24. By setting the insert rods 24 and the flow guiding holes 25, the yarn package 10 to be dyed can be sleeved on the insert rods 24. During dyeing, When the bobbin 2 enters the dyeing tank 1, the dyeing liquid flows in from one end of the insertion rod 24 and then flows through the guide hole 25 to the inner ring of the bobbin 10, so that the dyeing liquid can fully contact the yarn on the bobbin 10 and improve the dyeing effect of the yarn. The lower end face of the base 21 is provided with an end cap 26. Several fixing bolts 27 arranged in a ring array are threaded between the end cap 26 and the lower end face of the base 21. By setting the fixing bolts 27, the end cap 26 can be fixed to the lower end face of the base 21, and the end cap 26 can be disassembled for easy maintenance. One end of the fixed shaft 23 is provided with a limiting component 3. By setting the limiting component 3, the limiting component 3 can conveniently limit the yarn package 10 on the insertion rod 24, improve the convenience of the yarn package 10 limiting operation, and reduce the labor intensity of the operators. The base 21 is provided with a rotating component 5 and a vibration component 6 respectively. By setting the rotating component 5 and the vibration component 6, the rotating component 5 can rotate the insertion rod 24 through the equipment plate 22, thereby rotating the yarn package 10 on the insertion rod 24. The vibration component 6 can make the yarn package 10 on the insertion rod 24 vibrate slightly through the equipment plate 22, so that the yarn on the yarn package 10 is evenly contacted with the dyeing liquid, thereby improving the dyeing effect of the yarn.

[0029] The limiting component 3 includes a limiting disk 31, which is movably sleeved on one end of the fixed shaft 23. The limiting disk 31 has several annularly arranged insertion holes 32. One end of the insertion rod 24 passes through the insertion holes 32 into the limiting disk 31. By providing the insertion holes 32, the limiting disk 31 can be sleeved on the insertion rod 24. A rubber sleeve 33 is fixedly provided on the inner wall of the insertion holes 32. The outer wall of one end of the insertion rod 24 is in movable contact with the inner wall of the rubber sleeve 33. By providing the rubber sleeve 33, wear on the outer wall of the insertion rod 24 can be prevented. A rubber pad 34 is fixedly provided on the lower surface of the limiting disk 31. By providing the rubber pad 34, direct contact between the limiting disk 31 and the yarn package 10 can be prevented, thus avoiding damage to the yarn. Above the limiting disc 31, there is a sleeve 35. The sleeve 35 is movably sleeved on one end of the fixed shaft 23. A sliding sleeve 36 is rotatably installed on one end of the sleeve 35. The sliding sleeve 36 is movably sleeved on one end of the fixed shaft 23. Several connecting frames 37 are fixedly installed on the outer wall of the sliding sleeve 36. One end of the connecting frame 37 is fixedly connected to the upper surface of the limiting disc 31. By vertically raising and lowering the sleeve 35 at the top of the fixed shaft 23, the sleeve 35 can make the limiting disc 31 rise and fall synchronously through the sliding sleeve 36 and the connecting frame 37. When the sliding sleeve 36 rises and disengages from the top of the fixed shaft 23, the limiting disc 31 can be disengaged from the fixed shaft 23 and the insertion rod 24, so as to remove the yarn package 10 on the insertion rod 24. A threaded rod 38 is fixedly provided on the top wall of the sleeve 35, and a threaded hole 39 is provided at one end of the fixed shaft 23. The threaded rod 38 and the inner wall of the threaded hole 39 are rotatably connected by threads. By providing the threaded rod 38 and the threaded hole 39, when the sleeve 35 is rotated, the threaded rod 38 can rotate and rise and fall within the threaded hole 39, so that the sleeve 35 can rotate and rise and fall at the top of the fixed shaft 23. At the same time, the lowering height of the limiting plate 31 can be adjusted, that is, the downward pressure of the limiting plate 31 on the yarn package 10 can be adjusted according to the actual situation. A rotating seat 4 is fixedly provided at the other end of the sleeve 35. By providing the rotating seat 4, the sleeve 35 can be manually rotated through the rotating seat 4.

[0030] A U-shaped lifting ring 41 is rotatably installed on the outer wall of the other end of the sleeve 35. By setting the U-shaped lifting ring 41, it is convenient for the crane hook to lift and transfer the tube frame 2.

[0031] The rotating assembly 5 includes a rotating shaft 51 located inside the base 21 and coaxial with the fixed shaft 23. A hollow rod 52 is fixedly mounted on the other end of the fixed shaft 23. One end of the rotating shaft 51 is slidably mounted inside the hollow rod 52. By driving the rotating shaft 51 to rotate, the rotating shaft 51 can cause the fixed shaft 23 to rotate through the hollow rod 52. A through hole 53 is provided at the axial center of the equipment disk 22. The other end of the fixed shaft 23 is inserted into the through hole 53. Several slots 54 are provided on the peripheral wall of the through hole 53. Several retaining strips 55 are fixedly mounted on the other end of the fixed shaft 23. The locking strip 55 is slidably locked in the slot 54. By setting the slot 54 and the locking strip 55, when the fixed shaft 23 rotates, the fixed shaft 23 can rotate the equipment disk 22 through the locking strip 55 and the slot 54, thereby enabling the insertion rod 24 to rotate. A U-shaped fixing frame 56 is fixedly installed on the top wall of the base 21. A servo motor 57 is fixedly installed in the middle of the U-shaped fixing frame 56. The servo motor 57 is a waterproof motor. The drive output end of the servo motor 57 is fixedly connected to the other end of the rotating shaft 51. By starting the servo motor 57, the drive shaft of the servo motor 57 can make the rotating shaft 51 rotate.

[0032] The vibration assembly 6 includes two rotating rods 61, which are rotatably mounted on the side wall of the base 21. Each rotating rod 61 has a fixed cam 62, which are mirror images of each other. Driving the rotating rods 61 causes the cams 62 to rotate. A convex ring 63 is fixedly mounted on the lower surface of the equipment disk 22, with the two cams 62 located below it. By using the convex ring 63, when the protruding part of the cam 62 contacts the lower surface of the convex ring 63, the equipment disk 22 can rise through the convex ring 63, thereby causing the insertion rod 24 to... The yarn package 10 rises, and the retaining strip 55 slides up along the retaining groove 54. When the protruding part of the cam 62 disengages from the lower surface of the convex ring 63, the equipment disk 22 falls under its own weight, thereby realizing the vibration of the yarn package 10. A first bevel gear 64 is fixedly installed at the other end of the rotating shaft 51, and a second bevel gear 65 is fixedly installed at one end of each of the two rotating rods 61. The first bevel gear 64 meshes with the two second bevel gears 65. When the rotating shaft 51 rotates, the rotating shaft 51 can make the two rotating rods 61 rotate synchronously in opposite directions through the first bevel gear 64 and the two second bevel gears 65.

[0033] Working principle: When dyeing the yarn on the yarn package 10, firstly, each yarn package 10 is placed on multiple insert rods 24 one by one. Then, the sliding sleeve 36 is aligned with the top of the fixed shaft 23, and the insertion hole 32 is vertically aligned with the insert rod 24. Then, the rotating seat 4 is manually rotated, and the threaded rod 38 rotates into the threaded hole 39. The sliding sleeve 36 descends at the top of the fixed shaft 23, and the sleeve 35 rotates and descends at the top of the fixed shaft 23. The sliding sleeve 36 causes the limiting plate 31 to descend vertically through the connecting frame 37. The limiting plate 31 is placed on the insert rod 24 through the insertion hole 32 until the limiting plate 31 presses on the upper yarn package 10 (the yarn package 10 retains a certain upward movement space), thus limiting the yarn package 10 on the insert rod 24. This conveniently realizes the rapid limiting of the yarn package 10 during the dyeing process, effectively improving the convenience of the yarn package 10 limiting operation, and reducing the labor intensity of the operators. After the bobbin frame 2 is hoisted into the dyeing tank 1 by the overhead crane, the yarn on the bobbin 10 is dyed inside the dyeing tank 1 as the tank cover is closed. At the same time, the operator can start the servo motor 57 as needed, so that the drive shaft of the servo motor 57 rotates slowly. The drive shaft of the servo motor 57 causes the rotating shaft 51 to rotate. The rotating shaft 51 causes the fixed shaft 23 to rotate through the hollow rod 52. The fixed shaft 23 causes the equipment disk 22 to rotate through the clamping strip 55 and the clamping groove 54. The equipment disk 22 causes the bobbin 10 on the insertion rod 24 to rotate slowly through the insertion rod 24. Simultaneously, the rotating shaft 51 causes the two rotating rods 61 to rotate synchronously via the first bevel gear 64 and the two second bevel gears 65. The two rotating rods 61 cause the two cams 62 to rotate. When the protruding part of the cam 62 contacts the lower surface of the convex ring 63, the equipment disk 22 can be raised vertically through the convex ring 63, and the yarn package 10 on the insertion rod 24 rises synchronously. When the protruding part of the cam 62 disengages from the lower surface of the convex ring 63, the equipment disk 22 automatically descends under its own weight, and the yarn package 10 descends synchronously. As the cam 62 rotates, the yarn package 10 reciprocates up and down, generating slight vibrations. This conveniently realizes the rotation and vibration during the dyeing process of the yarn package 10, allowing the dyeing liquid in the dyeing tank 1 to fully contact the yarn on the yarn package 10, thereby improving the dyeing effect of the yarn.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
