Description

Technical Field

[0001] This utility model relates to the field of textile manufacturing technology, specifically to a textile dyeing device that facilitates color fixing. Background Technology

[0002] Textiles are various types of fabrics made through textile processes, typically including materials such as cotton, wool, silk, and synthetic fibers. These fabrics can be used to make clothing, home furnishings, decorations, and other textile products. Textiles have a wide range of uses and are ubiquitous in daily life. After textiles are made, they need to be dyed. The dyeing process mainly includes two key stages: the first stage is "dyeing," which is the transfer of dye from the dye bath to the fiber surface and diffusion into the fiber interior; the second stage is "color fixation," which is the use of chemical or physical methods to firmly fix the dye onto the fiber, thereby improving its color fastness. The quality of the color fixation directly determines the quality and durability of the final product.

[0003] A textile dyeing apparatus disclosed in publication number CN222226841U, although the utility model uses a stirring rod and a suction plate, and a heating plate to heat the pigment inside the chamber, during heating, a motor drives a fixed rod to rotate through a transmission structure, the fixed rod drives the stirring rod to rotate, the stirring rod mixes and stirs the pigment inside the chamber, and a liquid pump draws the pigment from the chamber through a suction pipe and a suction plate, and then transports the pigment into the chamber through an outlet pipe, thus achieving the effect of stirring and circulating the pigment inside the chamber during heating, making the pigment temperature uniform, and ensuring the dyeing quality.

[0004] However, this textile dyeing device has the following disadvantages: the textile is placed directly into the dyeing device, and during dyeing, it mainly relies on the circulation and convection of the dye liquor to achieve contact between the dye and the textile. However, for thick or tightly structured textiles, the dye liquor is difficult to penetrate into the fabric fully and evenly. During the color fixing stage, it may lead to inconsistent color fixing in different parts of the fabric, resulting in a "color spot" phenomenon, which seriously affects the product quality. Utility Model Content

[0005] The purpose of this invention is to provide a textile dyeing apparatus that facilitates color fixing, thereby solving the problem mentioned in the background art of not being able to improve the dyeing quality of textiles.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A textile dyeing apparatus for easy color fixing includes a dyeing tank, a feeding mechanism, a winding mechanism, and two sets of circulating pumps. The feeding mechanism is located at the feeding end of the dyeing tank, and the winding mechanism is located at the discharge end of the dyeing tank. The two sets of circulating pumps are installed on the side of the dyeing tank. A hollow central shaft is connected to the dyeing tank via an adjusting mechanism. An array of microwave generating units for color fixing is installed inside the hollow central shaft. A ceramic driven roller is rotatably connected to the hollow central shaft via a sealed bearing. A color fixing extrusion mechanism is located on one side of the dyeing tank, and two auxiliary mechanisms are located on the other side of the dyeing tank. A dyeing liquid extrusion assembly and a rotating extrusion roller are located at the discharge end of the dyeing tank. Multiple guide rollers are located inside the dyeing tank.

[0008] The color-fixing extrusion mechanism includes a second motor disposed on one side of the dyeing tank, and the output end of the second motor is connected to a main rotating roller.

[0009] The auxiliary mechanism includes a first motor installed on the other side of the dyeing tank, the output end of the first motor is connected to a connecting roller, and two flipping blades are connected to the connecting roller.

[0010] As a further embodiment of this utility model: the microwave generating unit array consists of multiple microwave generators and waveguides, and the power supply line and control line of the microwave generating unit array are introduced from the end of the hollow central shaft and pass through the internal space of the hollow central shaft to connect with the microwave generator.

[0011] As a further embodiment of this utility model: the microwave generating unit array is electrically connected to a microwave source controller, and the microwave generating unit array is also electrically connected to an external high-voltage power supply device.

[0012] As a further embodiment of this utility model: the adjustment mechanism includes a cylinder connected to the dyeing tank, a connecting plate fixedly connected to the top of the cylinder, a hollow adjusting rod connected to the bottom surface of the connecting plate, the hollow adjusting rod being connected to a hollow central shaft, and the interior of the hollow adjusting rod serving as a cable channel.

[0013] As a further embodiment of this utility model: a travel groove is provided on the inner side of the dyeing tank, and the travel groove allows the hollow adjusting rod to move within it.

[0014] As a further embodiment of this utility model: the extrusion dyeing liquid assembly includes two mounting seats connected to the discharge end of the dyeing tank, and a pneumatic push rod is fixedly connected to each of the two mounting seats. One end of the pneumatic push rod is connected to a driven extrusion roller.

[0015] As a further embodiment of this utility model: one end of the circulating pump is connected to the inside of the dyeing tank, and the other end of the circulating pump is connected to a delivery pipe, with several nozzles connected to the delivery pipe.

[0016] The beneficial effects of this utility model are:

[0017] 1. This textile dyeing device, which facilitates color fixation, achieves simultaneous compression and instantaneous microwave heating of the textile immersed in dye liquor during the dyeing process through the adjustment mechanism, hollow central shaft, microwave generator array, and ceramic driven roller. In use, the height of the hollow central shaft and ceramic driven roller is adjusted according to the thickness of the textile, allowing the textile to pass between the ceramic driven roller and the main rotating roller, thus compressing it. The textile immediately absorbs the surrounding dye liquor upon leaving the main rotating roller and driven roller, achieving "forced exchange" and maintaining a dynamic balance of dye liquor concentration inside and outside the fabric. Subsequently, the microwave generator array integrated inside the hollow central shaft heats the compressed area, causing the dye and water molecules inside the textile to heat up uniformly in a short time, rapidly achieving and completing the color fixation reaction. This effectively solves the "color mottled" problem caused by slow heat conduction and uneven dye liquor penetration in traditional dyeing devices, significantly improving the uniformity, efficiency, and color fastness of the finished product.

[0018] 2. This textile dyeing device, which facilitates color fixation, features an auxiliary mechanism. When in use, starting the first motor and connecting rollers drive the rotating blades to gently agitate the dye liquor, effectively breaking the temperature and concentration boundary layer of the dye liquor. This ensures the uniformity of temperature and composition of the dye liquor throughout the dyeing tank, providing a stable fluid environment for uniform dyeing and color fixation, and further guaranteeing the dyeing quality.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-5 As shown, a textile dyeing apparatus for easy color fixing includes a dyeing tank 1, a feeding mechanism 2, a winding mechanism 3, and two sets of circulating pumps 4. The feeding mechanism 2 is located at the feeding end of the dyeing tank 1, and the winding mechanism 3 is located at the discharge end of the dyeing tank 1. The two sets of circulating pumps 4 are installed on the side of the dyeing tank 1. A hollow central shaft 6 is connected to the dyeing tank 1 via an adjusting mechanism 5. A microwave generating unit array 7 for color fixing is installed inside the hollow central shaft 6. A ceramic driven roller 16 is rotatably connected to the hollow central shaft 6 via a sealed bearing. A color fixing extrusion mechanism 8 is provided on one side of the dyeing tank 1, and two auxiliary mechanisms 9 are provided on the other side of the dyeing tank 1. A dyeing liquid extrusion assembly 10 and a rotating extrusion roller 11 are provided at the discharge end of the dyeing tank 1. Multiple guide rollers 12 are provided inside the dyeing tank 1.

[0028] The color-fixing extrusion mechanism 8 includes a second motor 801 located on one side of the dyeing tank 1. The output end of the second motor 801 is connected to a main rotating roller 802. By adjusting the mechanism 5, the hollow central shaft 6, the microwave generating unit array 7, and the ceramic driven roller 16, the textiles immersed in the dye liquor are simultaneously extruded and instantaneously microwave heated during the dyeing process. This effectively solves the problem of "color spots" caused by slow heat conduction and uneven dye liquor penetration in traditional dyeing devices, and significantly improves the uniformity, efficiency, and color fastness of the finished product.

[0029] The auxiliary mechanism 9 includes a first motor 901 installed on the other side of the dyeing tank 1. The output end of the first motor 901 is connected to a connecting roller 902. Two flipping blades 903 are connected to the connecting roller 902. By setting up the auxiliary mechanism 9, the temperature and concentration boundary layer of the dye solution is effectively broken, ensuring the uniformity of the temperature and composition of the dye solution in various parts of the dyeing tank 1, providing a stable fluid environment for uniform dyeing and color fixing, and further ensuring the dyeing quality.

[0030] like Figure 3 As shown, the microwave generating unit array 7 consists of multiple microwave generators and waveguides. The power supply and control lines of the microwave generating unit array 7 are introduced from the end of the hollow central shaft 6 and pass through the internal space of the hollow central shaft 6 to connect with the microwave generators. The microwave generating unit array 7 is electrically connected to a microwave source controller 17 and is also electrically connected to an external high-voltage power supply. By setting up the microwave generating unit array 7, multiple miniaturized microwave generators are arranged axially along the hollow central shaft 6 and guided by the waveguides, which generates a uniform and powerful microwave field at the compression point, and performs instantaneous and efficient bulk heating of the fabric, directly stimulating the color-fixing chemical reaction.

[0031] like Figure 3 As shown, the adjustment mechanism 5 includes a cylinder 501 connected to the dyeing tank 1. A connecting plate 502 is fixedly connected to the top of the cylinder 501. A hollow adjustment rod 503 is connected to the bottom surface of the connecting plate 502. The hollow adjustment rod 503 is connected to the hollow central shaft 6. The interior of the hollow adjustment rod 503 serves as a cable channel. The adjustment mechanism 5 is designed to precisely control the gap between the ceramic driven roller 16 and the main rotating roller 802 to accommodate fabrics of different thicknesses and materials and to ensure a stable extrusion effect. At the same time, the hollow adjustment rod 503 serves as a cable channel, providing a safe and concealed path for the power supply and control of the microwave generating unit array 7.

[0032] like Figure 2 As shown, a stroke groove 13 is provided on the inner side of the dyeing tank 1. The stroke groove 13 allows the hollow adjusting rod 503 to move inside. By setting the stroke groove 13, the movement trajectory of the hollow adjusting rod 503 is guided and restricted, ensuring that the ceramic driven roller 16 moves smoothly in the vertical direction and preventing the mechanism from jamming.

[0033] like Figure 5 As shown, the dyeing liquor assembly 10 includes two mounting seats connected to the discharge end of the dyeing tank 1. A pneumatic push rod 1001 is fixedly connected to each of the two mounting seats. One end of the pneumatic push rod 1001 is connected to a driven extrusion roller 1002. By setting up the dyeing liquor assembly 10, controllable pressure is applied to the fabric before it leaves the dyeing tank 1, and excess dye liquor is squeezed out, thereby improving dye utilization and reducing the subsequent drying load.

[0034] like Figure 4 As shown, one end of the circulation pump 4 is connected to the inside of the dyeing tank 1, and the other end of the circulation pump 4 is connected to the delivery pipe 14. Several nozzles 15 are connected to the delivery pipe 14. Through the setting of the circulation pump 4, the dye liquor is drawn from the bottom of the dyeing tank 1 and sprayed back onto the fabric surface or into the dye liquor through the nozzles 15, so as to realize the forced circulation and mixing of the dye liquor and maintain the dynamic uniformity of temperature and concentration of the entire system.

[0035] The working principle of this utility model is as follows: During operation, the textile is drawn out from the feeding mechanism 2 and guided by multiple guide rollers 12, and fully immersed in the dyeing liquid in the dyeing tank 1. The circulating pump 4 continuously circulates the dye liquid through the conveying pipe 14 and the nozzle 15, while the rotating blade 903 of the auxiliary mechanism 9 rotates slowly to help maintain the uniformity of the dye liquid. The fully immersed textile first enters the color-fixing extrusion area composed of the main rotating roller 802 and the ceramic driven roller 16, which forces the exchange and uniform distribution of the dye liquid inside the textile. The microwave generating unit array 7 integrated inside the hollow central shaft 6 is activated, and the generated microwave energy penetrates the wall of the ceramic driven roller 16 and acts directly on the extruded textile. The microwave energy causes the water molecules and dye molecules inside the textile to vibrate and rub at high speed, raising the entire fabric to the temperature required for color fixing in a very short time, thereby completing the rapid and uniform fixation of the dye. After color fixing is completed, the fabric continues to move to the discharge end, where it is squeezed for the last time by the dyeing liquid extrusion assembly 10 and the rotating extrusion roller 11 to recover the excess dye liquid. Finally, it is wound up by the winding mechanism 3.

[0036] It should be noted that the device structure and accompanying drawings of this utility model mainly describe the principle of this utility model.
