Technical Field
[0001] The invention relates to the technical field of dyeing devices, in particular to a cationic polyester composite yarn dyeing device. Background Art
[0002] Cationic polyester composite yarn, also known as Wulong yarn or Yilongsha, is a fabric made from cationic dyeable polyester and conventional polyester through a ply-stranded and texturized process. Its characteristics include: A unique two-color effect: Through uneven air entanglement, varying pitch lengths are produced, allowing the fabric surface to exhibit two alternating tones, adding a rich visual dimension. Different cationic ratios can achieve different two-color effects, such as contrasting colors, varying shades, and white space. Excellent performance: It exhibits excellent drape, a rich hand feel, an elegant luster, a delicate surface effect, and multiple textures. The fabric is soft, fade-resistant, wrinkle-resistant, and wear-resistant, making it breathable and comfortable to wear. Wide range of applications: It can be used in the production of a variety of garments, including long skirts and suits, jackets and sportswear, trousers, and thick fabrics. It is also suitable for home textile decorative fabrics and anti-static product design.
[0003] When dyeing cationic polyester composite yarn, in traditional dyeing technology, the dyeing process is mostly static. In the common intermittent dyeing tank, the dye liquid flow rate is slow, and the contact time and concentration of the dye liquid between different parts of the fiber are different, resulting in different shades of color and obvious color difference in the dyed composite yarn. This uneven dyeing not only affects the appearance quality of the product, but also increases the subsequent sorting and rework costs, reducing production efficiency; the dehydration and drying process after dyeing is also inefficient. In the past, it relied on natural drying or simple squeezing to remove moisture, which was time-consuming and difficult to dry thoroughly. This not only limited the production cycle, but also required a large amount of space for drying for large-scale production, increasing operating costs; the inspection process mostly relied on manual sampling, which was highly subjective and easy to miss. Manual inspection was affected by factors such as fatigue and experience differences, and it was difficult to detect minor dyeing defects. To address the above problems, a cationic polyester composite yarn dyeing device is proposed. Summary of the Invention

A first motor 16 for driving the rotating shaft 14 is fixedly installed in the middle of the rear side of the immersion tank 2. The stirring blades 15 rotate under the drive of the first motor 16, which can promote the circulation of the dye solution, so that the cathodic-polyester composite yarn is fully in contact with the dye solution, ensure uniform dyeing depth, avoid uneven dyeing, and improve dyeing quality. At the same time, the speed of the stirring blades 15 can be automatically adjusted according to the material of the composite yarn to meet the dyeing requirements of composite yarns of different materials.
[0023] Specifically, the lower end of the front side of the dyeing tank 2 is fixedly connected to the sewage pipe 9, and a valve is installed on the sewage pipe 9.

Two second rotating seats 12 are fixedly connected to the right side of the marking assembly 8 above the second stand 4, and a guide roller 13 is rotatably connected between the two second rotating seats 12. The tension detection roller 11 can adopt the detection roller of German Honigmann CSW. The guide roller 13 can guide the dyed cathodic polyester composite yarn, so that the composite yarn can smoothly enter the subsequent winding or other processes, thereby ensuring the smoothness of the entire production process.
[0024] Specifically, the pretreatment component 1 includes a first stand 101, which is fixedly connected to a steam box 102 on the top. A feed port 103 is provided on the left side of the steam box 102, and a discharge port 104 is provided on the right side of the steam box 102.

Steam of different temperatures is introduced through the first steam inlet pipe 105 and the second steam inlet pipe 106 respectively. For example, the high-temperature steam in the upper section can effectively soften the fiber, and the medium-temperature steam in the lower section can be evenly preheated. This segmented steam treatment method can make the fiber structure more fluffy, thereby increasing the affinity of the cationic polyester composite yarn to the dye, creating good conditions for subsequent dyeing processes, and improving the dyeing quality.

The mounting strips 306 are slidably connected to the guide rods 301 through guide sleeves. The first cylinder 303 serves as a power source and can accurately control the up and down movement of the connecting plate 304, thereby adjusting the height of the first adjusting roller 307 to achieve dynamic adjustment of the tension of the cationic polyester composite yarn.
[0026] Specifically, the tension adjustment assembly 3 also includes three first adjusting rollers 307 and two second adjusting rollers 308.

The first adjusting rollers 307 and the second adjusting rollers 308 are staggered with each other. The cationic polyester composite yarn forms an "S"-shaped path through the first adjusting rollers 307 and the second adjusting rollers 308 to be immersed in the immersion tank 2. This path design can increase the residence time of the composite yarn in the dye solution and improve the dyeing effect. At the same time, by adjusting the height of the first adjusting roller 307, the tension of the composite yarn can be accurately controlled to ensure the stability of the dyeing process.
[0027] Specifically, the extrusion assembly 5 includes four mounting columns 501, and the four mounting columns 501 are fixedly connected to the front and rear sides of the second platform 4 in groups of two.

The output ends of the two groups of second cylinders 503 pass through the two support bars 502 and are fixedly connected to the moving bar 504. A dovetail groove 506 is provided on the side of the four mounting columns 501 close to the moving bar 504. The second cylinder 503 can drive the moving bar 504 to move up and down, thereby controlling the clamping force between the first extrusion roller 507 and the second extrusion roller 509, thereby realizing the effective extrusion and removal of excess dye liquid of the cationic polyester composite yarn.
[0028] Specifically, at least five first squeezing rollers 507 are rotatably connected between the two moving bars 504, and dovetail sliders 505 are fixedly connected to the left and right ends of the two moving bars 504. The dovetail sliders 505 are slidably connected to the inside of the dovetail chute 506. A fixed bar 508 is fixedly connected between the front and rear two sets of mounting columns 501. At least five second squeezing rollers 509 are rotatably connected between the two fixed bars 508. The first squeezing rollers 507 and the second squeezing rollers 509 are arranged corresponding to each other. A drainage groove 510 is fixedly connected between the front and rear mounting columns 501. The drainage groove 510 The lower end of the dovetail chute 506 extends into the interior of the dyeing tank 2. The cooperation of the dovetail slide 506 and the dovetail slider 505 makes the moving bar 504 more stable and precise during the movement, reduces shaking and deviation, and ensures the consistency of the extrusion effect. The cooperation of multiple first extrusion rollers 507 and second extrusion rollers 509 can increase the extrusion area of the composite yarn, improve the extrusion efficiency, remove excess dye, and reduce the waste of dye. The drainage trough 510 can return the extruded dye to the dyeing tank 2 in time for recycling, realize dye recovery, reduce production costs, and avoid dye pollution to the environment.
[0029] Specifically, the air-drying component 6 includes an air-drying hood 601, which is fixedly connected to the leftmost side of the upper surface of the second stand 4.

At least three axial flow fans 604 are fixedly connected to the upper part of the air-drying hood 601. The air-drying hood 601 provides a relatively closed space for drying the cationic polyester composite yarn, reducing the influence of the external environment on the drying effect. The heating rods 603 raise the internal temperature of the air-drying hood 601 to 80-100°C, and the axial flow fan 604 blows on the surface of the composite yarn to quickly evaporate the moisture on the surface of the composite yarn, thereby improving the drying efficiency and meeting the requirements of subsequent detection and marking.
[0030] Specifically, the detection component 7 includes a light shield 701, the bottom of the light shield 701 is fixedly connected to the upper surface of the second stand 4, and a second slot 702 is provided on the lower ends of the left and right sides of the light shield 701. A light bar 703 is fixedly connected to the lower part of the light shield 701, and at least three groups of visual detection CCD704 are fixedly connected to the top surface of the light shield 701.

The output end of the electric telescopic rod 806 is fixedly connected to a fixed plate 807, and the bottom surface of the fixed plate 807 is fixedly connected to a marking pen 808. The pigment of the marking pen 808 is gouache pigment, which is easily soluble in water and can be easily washed off after encountering water. The second motor 804 drives the threaded rod 802 to rotate, and drives the moving block 805 to move along the limit column 803 to achieve precise adjustment of the position of the marking pen 808. The electric telescopic rod 806 can control the up and down movement of the marking pen 808, so that the marking pen 808 can accurately print the qualified mark on the surface of the composite wire, thereby marking qualified products.
[0032] Working principle: According to Figure 1In the direction shown, the cationic polyester composite yarn is drawn through the pretreatment component 1, the tension adjustment component 3, the bottom of the tension detection roller 11, the extrusion component 5, the air-drying component 6, the detection component 7 and the marking component 8 in sequence, and is connected to the external winding mechanism, so that the cloth is in contact with the dye solution inside the dyeing tank 2. The cationic polyester composite yarn enters the steam box 102 from the feed port 103, and the first steam inlet pipe 105 and the second steam inlet pipe 106 are respectively fed with steam of different temperatures (such as high-temperature steam in the upper section to soften the fiber, and medium-temperature steam in the lower section to evenly preheat it), so that the fiber structure is fluffy and the dyeing affinity is improved. The pretreated composite yarn is output from the discharge port 104, and the composite yarn passes through the tension adjustment component 3. The first adjusting roller 307 and the second adjusting roller 308 form an "S"-shaped path and immerse the composite yarn in the dyeing tank 2. The first motor 16 drives the rotating shaft 14 and the stirring blade 15 to rotate, promoting the circulation of the dye solution so that the composite yarn is fully in contact with the dye solution. The temperature of the dye solution is maintained at 60-90°C by the temperature control system (adjusted according to the type of dye). The speed of the stirring blade 15 is automatically adjusted according to the material of the composite yarn to ensure uniform dyeing depth. The dyed composite yarn enters the extrusion assembly 5 through the guide roller 13. The second cylinder 503 drives the moving bar 504 to move downward. The first extrusion roller 507 and the second extrusion roller 509 clamp the composite yarn to remove 70% to 80% of the excess dye solution. The extruded dye solution The dye is recycled through the drainage trough 510 to the dyeing tank 2 for dye recovery. The composite yarn enters the air drying hood 601 through the first notch 602. The heating rod 603 raises the internal temperature to 80-100°C. The axial flow fan 604 blows on the surface of the composite yarn to quickly evaporate the moisture on the surface of the composite yarn. The air-dried composite yarn meets the requirements of subsequent inspection and marking. The composite yarn enters the inspection component 7 through the second notch 702. The light bar 703 in the light shield 701 provides uniform lighting. The visual inspection CCD 704 performs real-time scanning of the dyeing quality. The inspection items include color uniformity, stains, and breakage. The qualified products send signals to the marking component 8 through the control box 705. The second motor 804 drives the threaded rod 802 to rotate, and the moving block 805 drives the marking pen 808 to move to the specified position. The electric telescopic rod 806 descends, and the marking pen 808 prints a qualified mark on the surface of the composite yarn. Unqualified products are marked as defective and are manually rejected or re-dyed. The sewage pipe 9 at the bottom of the immersion and dyeing tank 2 regularly discharges sediment, and the valve controls the discharge speed to avoid large-scale loss of dye solution. During the entire process, the tension detection roller 11 monitors the tension of the composite yarn in real time. If the tension fluctuation exceeds the preset range, the control system automatically adjusts the stroke of the first cylinder 303 and realizes dynamic tension compensation by adjusting the height of the first adjusting roller 307 to ensure a stable dyeing process.
