Description

Technical Field

[0001] This utility model relates to the field of colored yarn dyeing technology, and in particular to a multi-channel uniform dyeing mechanism for colored yarn. Background Technology

[0002] Yarn dyeing equipment is commonly used in the textile industry. It involves placing the yarn to be dyed or colored yarn into a dye bath, where the yarn surface and internal fibers fully absorb the dye through immersion and dye penetration, thus achieving overall coloring or color correction of the yarn. As an important dyeing process in the textile industry, yarn dyeing directly affects the color uniformity, appearance quality, and stability of subsequent products. Currently, yarn dyeing typically uses single-channel or multi-channel dyeing equipment. Colored yarn enters the dyeing bath through a single or multiple channels for dyeing. With multiple channels, different dyes can be poured into different channels, allowing different colors of yarn to be dyed in the same batch.

[0003] Traditional dyeing facilities often use static immersion or simple unidirectional movement of yarn to immerse the yarn in the dye bath. However, when dyeing large batches, multi-strand or high-density yarns, the dye absorption of the internal fiber layer of the yarn is insufficient, resulting in insufficient contact between the dye liquor and the yarn. This leads to differences in the dyeing effect between the yarn surface and the internal fibers, which can easily cause color differences. The dye liquor cannot penetrate into the yarn, resulting in an undesirable phenomenon of "lighter inside and darker outside," which affects the uniformity of dyeing. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a multi-channel uniform dyeing mechanism for colored yarn, so as to solve the problems of insufficient contact between dye liquor and yarn, difference in dyeing effect between yarn surface and internal fiber, easy formation of color difference, and difficulty in dye liquor penetrating into the yarn.

[0005] To achieve the above objectives, this utility model provides a multi-channel uniform dyeing mechanism for colored yarn, including a dyeing tank. Fixed plates are fixedly connected to both sides of the dyeing tank. A rotating rod is rotatably connected between the opposing surfaces of the fixed plates. Multiple evenly distributed spools are fixedly connected to the outer walls of the rotating rod. A servo motor is fixedly connected to the side walls of the fixed plates. The output end of the servo motor is fixedly connected to one end of the rotating rod. Multiple evenly distributed dyeing troughs are opened at the top of the dyeing tank. A uniform dyeing mechanism for dyeing colored yarn is provided inside the dyeing tank.

[0006] Preferably, the uniform dyeing mechanism includes a stirring rod, one end of which penetrates the inner wall of multiple equally spaced and uniformly distributed dyeing tanks and extends out of the outer wall of the dyeing tank. A sealing ring is provided between the stirring rod and the dyeing tank. Stirring blades are fixedly connected to the outer wall of the stirring rod inside the multiple equally spaced and uniformly distributed dyeing tanks. A belt is provided between the outer wall of one end of the stirring rod and the outer wall of one end of the rotating rod through a pulley.

[0007] Preferably, the uniform dyeing mechanism further includes support plates fixedly connected to both sides of the top of the dyeing tank. Each support plate has a through groove on its sidewall. A sliding plate is slidably connected between two through grooves. Multiple equally spaced and uniformly distributed lower pressure plates are fixedly connected to the bottom of each sliding plate. These lower pressure plates are located inside multiple equally spaced and uniformly distributed dyeing tanks. Lower pressure rollers are rotatably connected to the bottom sides of each lower pressure plate. A rotating plate is fixedly connected to the outer wall of one end of the stirring rod. A rotating block is fixedly connected to the top of the rotating plate. Reciprocating rods are slidably connected to the outer walls of both sides of the dyeing tank. The top of the reciprocating rods is fixedly connected to the sidewall of the sliding plate. An inner sliding groove plate is fixedly connected to the bottom of the reciprocating rods. The rotating block is slidably connected inside the inner sliding groove plate.

[0008] Preferably, two sets of horizontal plates are fixedly connected to the top of the dyeing tank on both sides. A connecting rod is rotatably connected to the side wall of each set of horizontal plates. An upper pressure roller is rotatably connected between the opposite sides of the connecting rods on the side walls of the two sets of horizontal plates. A spring telescopic rod is rotatably connected between the side wall of the connecting rod and the side wall of the horizontal plate.

[0009] Preferably, both ends of the top of the dyeing tank are rotatably connected to guide rollers for guiding the colored yarn.

[0010] Preferably, the outer wall of the stirring blades is provided with perforations.

[0011] The beneficial effects of this utility model are:

[0012] 1. This multi-channel uniform dyeing mechanism effectively solves the problems of uneven dyeing and "lighter inside, darker outside" coloring in existing technologies. By installing the roll on the outer wall of the rotating rods at both ends of the dyeing tank, and cooperating with the servo motor to drive the colored yarn to circulate and transport within the dyeing tank, it ensures that the colored yarn is fully immersed in the dye liquor, improving the initial dyeing effect. At the same time, through the linkage of the stirring rod with the rotating plate, rotating block, inner sliding plate, reciprocating rod, sliding plate, lower pressure plate, and lower pressure roller, the colored yarn achieves continuous up-and-down reciprocating motion within the dyeing tank, dynamically increasing the contact area between the colored yarn and the dye liquor, promoting the rapid penetration of the dye liquor into the inner fiber layer of the yarn, significantly improving the uniformity of yarn dyeing, avoiding the phenomenon of "lighter inside, darker outside" coloring, and further accelerating the dyeing reaction rate, shortening the dyeing time, and improving dyeing production efficiency and product quality.

[0013] 2. This multi-channel uniform dyeing mechanism for colored yarn uses a rotating rod to drive a stirring rod to rotate, which in turn drives the stirring blades to rotate at high speed. During the rotation of the stirring blades, the perforated structure on its outer wall allows the dye liquor to flow smoothly from inside and outside the perforations, forming a good circulation effect, improving stirring efficiency, effectively preventing dye liquor stratification and sedimentation, maintaining the uniformity of the dye liquor, and further promoting the uniform distribution of the dye liquor on the yarn surface.

[0024] like Figures 1 to 5 As shown, a multi-channel uniform dyeing mechanism for colored yarn includes a dyeing tank 1, fixed plates 2 fixedly connected to both sides of the dyeing tank 1, rotating rods 3 rotatably connected between opposite surfaces of the fixed plates 2, multiple evenly distributed rolls 4 fixedly connected to the outer walls of the rotating rods 3, servo motors 5 fixedly connected to the side walls of the fixed plates 2, the output end of the servo motors 5 fixedly connected to one end of the rotating rods 3, multiple evenly distributed dyeing tanks 6 are opened at the top of the dyeing tank 1, and a uniform dyeing mechanism for dyeing colored yarn is provided inside the dyeing tank 1.

[0025] Further, see attached document. Figures 2 to 4 As shown, the uniform dyeing mechanism includes a stirring rod 7. One end of the stirring rod 7 penetrates the inner wall of multiple equally spaced and uniformly distributed dyeing tanks 6 and extends out of the outer wall of the dyeing pool 1. A sealing ring is provided between the stirring rod 7 and the dyeing pool 1. Stirring blades 8 are fixedly connected to the outer wall of the stirring rod 7 inside the multiple equally spaced and uniformly distributed dyeing tanks 6. A belt 9 is fitted between the outer wall of one end of the stirring rod 7 and the outer wall of one end of the rotating rod 3 through a pulley. The uniform dyeing mechanism also includes support plates 10 fixedly connected to both sides of the top of the dyeing pool 1. The side walls of the support plates 10 are provided with through grooves 11, and a sliding plate 12 is slidably connected between two through grooves 11. Multiple equal-distance and evenly distributed lower pressure plates 13 are fixedly connected to the bottom of the slide plate 12. The multiple equal-distance and evenly distributed lower pressure plates 13 are all inside the multiple equal-distance and evenly distributed dyeing tanks 6. Lower pressure rollers 14 are rotatably connected to the bottom sides of the lower pressure plates 13. A rotating plate 15 is fixedly connected to the outer wall of one end of the stirring rod 7. A rotating block 16 is fixedly connected to the top of the rotating plate 15. Reciprocating rods 17 are slidably connected to the outer walls of both sides of the dyeing tank 1. The top of the reciprocating rod 17 is fixedly connected to the side wall of the slide plate 12. An inner sliding groove plate 18 is fixedly connected to the bottom of the reciprocating rod 17. The rotating block 16 is slidably connected inside the inner sliding groove plate 18.

[0026] When using this uniform dyeing mechanism, firstly, the roll 4 is installed on the outer wall of the rotating rod 3 at one end of the dyeing tank 1, and an empty roll 4 is installed at the other end of the dyeing tank 1. Then, one end of the colored yarn is passed around the outer wall of the upper pressure roller 21, the guide roller 23 and the lower pressure roller 14 in sequence and fixed on the empty roll 4. Then, the servo motors 5 at both ends are started. The servo motors 5 drive the rotating rods 3 at both ends of the dyeing tank 1 to rotate in the same direction, so that the colored yarn is circulated in the dyeing tank 6 and the dye in the dyeing tank 6 dyes the colored yarn.

[0027] When the rotating rod 3 rotates, the stirring rod 7 rotates in conjunction with the belt 9. The stirring rod 7 then drives the stirring blade 8 to rotate. During the rotation, the stirring blade 8 fully stirs the dye liquor in the dyeing tank 6. With the leakage holes provided on the outer wall of the stirring blade 8, the dye liquor can be effectively circulated and homogeneously stirred, avoiding dye stratification or sedimentation and maintaining the uniformity of the dye liquor.

[0028] At the same time, the stirring rod 7 rotates and drives the rotating plate 15 below to rotate. The rotating plate 15 drives the rotating block 16 to rotate along the circumferential path. The rotating block 16 slides under the guidance of the inner sliding plate 18 and simultaneously pushes the inner sliding plate 18 to achieve up-and-down reciprocating motion. During the movement of the rotating block 16, it also drives the reciprocating rod 17 to move up and down, thereby driving the slide plate 12 to drive the lower pressure plate 13 and the lower pressure roller 14 to move up and down simultaneously, forming a dynamic pressure and release action on the colored yarn, thereby increasing the contact area of ​​the yarn dye liquor, improving the dyeing uniformity, promoting the penetration and diffusion of the dye liquor on the yarn, and also accelerating the dyeing reaction rate and reducing the dyeing time.

[0029] This uniform dyeing mechanism effectively solves the problems of uneven yarn dyeing and "shallow inside and dark outside" in existing technologies. By installing the roll 4 on the outer wall of the rotating rods 3 at both ends of the dyeing tank 1, and cooperating with the servo motor 5 to drive the colored yarn to circulate and transport within the dyeing tank 6, it ensures that the colored yarn is fully immersed in the dye liquor, improving the initial dyeing effect. At the same time, through the linkage of the stirring rod 7 with the rotating plate 15, rotating block 16, inner sliding plate 18, reciprocating rod 17, sliding plate 12, lower pressure plate 13, and lower pressure roller 14, the colored yarn achieves continuous up-and-down reciprocating motion within the dyeing tank 6, dynamically increasing the contact area between the colored yarn and the dye liquor, promoting the rapid penetration of the dye liquor into the inner fiber layer of the yarn, and significantly improving the yarn quality. The uniformity of dyeing is improved, avoiding the phenomenon of "lighter inside and darker outside". At the same time, it can further accelerate the dyeing reaction rate, shorten the dyeing time, and improve the dyeing production efficiency and product quality. Meanwhile, the rotation of the rotating rod 3 drives the stirring rod 7 to rotate, which in turn drives the stirring blade 8 to rotate at high speed. During the rotation of the stirring blade 8, the perforated structure on its outer wall allows the dye liquor to flow smoothly from inside and outside the perforations, forming a good circulation flow effect, improving stirring efficiency, effectively preventing dye liquor stratification and sedimentation, and continuously maintaining the uniformity of the dye liquor. This further promotes the uniform distribution of the dye liquor on the yarn surface and significantly improves the color difference problem during the yarn dyeing process.

[0030] Further, see attached document. Figure 5 As shown, two sets of horizontal plates 19 are fixedly connected to the top of the dyeing tank 1 on both sides. Connecting rods 20 are rotatably connected to the side walls of the two sets of horizontal plates 19. Upper pressure rollers 21 are rotatably connected between the opposite sides of the connecting rods 20 on the side walls of the two sets of horizontal plates 19. Spring telescopic rods 22 are rotatably connected between the side walls of the connecting rods 20 and the side walls of the horizontal plates 19. When the lower pressure roller 14 pushes the colored yarn downward, the upper pressure rollers 21 at both ends of the dyeing tank 1 will rotate to one side due to the tension of the colored yarn through the connecting rods 20. When the connecting rods 20 rotate, they will compress the spring telescopic rods 22, thereby ensuring the length required for the colored yarn to reciprocate in the dyeing tank 6.

[0031] Further, see attached document. Figure 2 As shown, guide rollers 23 for guiding colored yarn are rotatably connected to both ends of the top of the dyeing tank 6. The guide rollers 23 can guide the colored yarn into the dyeing tank 6.
