Description

Technical Field

[0001] This utility model relates to fabric dyeing equipment, and more specifically, to a pressure dyeing device for fluorescent fabrics. Background Technology

[0002] Fluorescent fabrics offer a striking visual effect and are well-suited for specific environments, such as outdoor workwear, warning clothing, and waterproof jackets. Currently, the dyeing process typically involves immersing the fabric in dye to allow the dye to adhere to the surface, followed by processes like color fixing and drying to achieve the desired color. However, because the inner layers of the fabric contain some voids that may contain water or other reagents, the dye cannot adhere to these layers, resulting in most of the dyeing effect remaining on the surface. This leads to poor dyeing results in fluorescent fabrics, and after use, the surface is prone to wear and tear, further hindering color adhesion.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

Detailed Implementation

[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This embodiment discloses a pressure dyeing apparatus for fluorescent fabrics, referring to... Figure 1-3 As shown, it includes a pool body 1 and two sets of pressure rollers 7. The two sets of pressure rollers 7 can squeeze the fluorescent fabric to be dyed. After squeezing, the air and reagents remaining in the fabric will be squeezed out. After the fabric leaves the squeezing position, it will expand again. The dyeing reagent in the pool body 1 can be absorbed into the fabric, which can increase the amount of reagent adhering to the fabric, especially for the dyeing effect in the center of the fabric.

[0027] Reference Figure 2 , 3 As shown, in this embodiment, the pressure roller assembly 7 includes a support frame 70, a first pressure roller 71, a second pressure roller 72, and a third pressure roller 73. The first pressure roller 71, the second pressure roller 72, and the third pressure roller 73 are installed sequentially on the support frame 70 from bottom to top. The axes of the first pressure roller 71, the second pressure roller 72, and the third pressure roller 73 are vertically aligned and can abut against each other in the vertical direction to compress the fabric being passed through.

[0028] Specifically, the lower side of pressure roller 2 72 can abut against the upper side of pressure roller 1 71, and the upper side of pressure roller 2 72 can abut against the lower side of pressure roller 3 73. When the fabric is wound around, it first passes between pressure roller 1 71 and pressure roller 2 72, then around pressure roller 2 72, passes between pressure roller 2 72 and pressure roller 3 73, and then is output backward.

[0029] During the fabric re-winding process, pressure rollers 71, 72, and 73 work together to squeeze the fabric. The pressure is primarily concentrated on the upper and lower pressure points of pressure roller 72, creating a double-squeezing and re-adsorption effect. Furthermore, pressure rollers 71 and 72 are located within the tank 1 and submerged below the liquid surface, ensuring that the reagent in the tank 1 can be re-absorbed during the fabric's recovery process after squeezing. Through repeated squeezing, air and other reagents adhering to the fabric are effectively expelled, ensuring that the dye reagent can be effectively absorbed into the fabric.

[0030] In this embodiment, pressure roller 1 71 and pressure roller 3 73 are metal rollers, and pressure roller 2 72 has a rubber layer covering its outer periphery, giving it a certain degree of elasticity. During the pressing process between the outer periphery of pressure roller 2 72 and the metal roller, pressure roller 2 72 can undergo slight deformation, thereby increasing the compression area between pressure roller 2 72 and the corresponding metal roller, effectively applying a compression effect to the fabric. Moreover, in this embodiment, the diameter of pressure roller 3 73 is smaller than that of pressure roller 2 72 and pressure roller 3 73, while the shape and size of pressure roller 2 72 and pressure roller 3 73 are basically the same.

[0031] Reference Figure 2 As shown, a brush roller 77 is also installed on the outside of the pressure roller 72. The brush roller 77 can brush the fabric that passes around the pressure roller 72 to remove impurities attached to the surface of the fabric on that side, and prevent impurities from adhering to the fabric surface during repeated squeezing.

[0032] In pressure roller group 7, pressure roller 2 (72) and pressure roller 3 (73) exert pressure through gravity, further compressing the fabric being passed through. (Refer to...) Figure 3As shown, the pressure roller 71 has a rotating shaft 711, the two ends of which are rotatably mounted on the support frame 70. The axis of the pressure roller 71 is fixed to the support frame 70 and can only rotate.

[0033] Pressure rollers 72 and 73 are located above pressure roller 71 and can be adjusted upwards to accommodate fabrics of different thicknesses. Specifically, pressure roller 72 has a rotating shaft 721, with sliders 722 rotatably connected to both ends of the rotating shaft 721. Slider 722 is slidably mounted vertically on the support frame 70. Pressure roller 73 has a rotating shaft 731, with sliders 732 rotatably mounted to both ends of the rotating shaft 731. Slider 732 is slidably mounted vertically on the support frame 70. The support frame 70 has vertically oriented grooves 701, within which sliders 722 and 732 are slidably mounted, providing stable guidance for the vertical movement of pressure rollers 72 and 73.

[0034] In addition, a spring 75 is elastically pressed against the upper side of the second slider 732. The spring 75 applies additional downward pressure to the second slider 732, which can adjust the pressure of the pressure roller group 7 and ensure that the fabric can be squeezed by sufficient pressure.

[0035] A slider three 74 is slidably connected within the slide groove 701. Slider three 74 is located above slider two 732, and spring 75 elastically presses against slider two 732 and slider three 74. Furthermore, a limiting part 702 is fixed to the upper end of the slide groove 701, and an adjusting screw 76 is threadedly connected to the limiting part 702. The adjusting screw 76 is vertically oriented. The lower end of the adjusting screw 76 extends into the slide groove 701 and abuts against the upper side of the limiting part 702. By adjusting the screw 76 threaded up and down, the squeezing effect of slider three 74 on spring 75 can be adjusted, thereby adjusting the pressure on the fabric to meet the fabric's pressure requirements.

[0036] In addition, a limiting groove 741 is provided on the lower side of slider 3 74, and the upper end of spring 75 is embedded in the limiting groove 741, which can limit the position of spring 75 to maintain the positional stability of spring 75 and ensure that a stable pressure supplement can be formed on slider 3 74.

[0037] In this embodiment, the pool body 1 is provided with vertical partition 1 2 and partition 2 3. Partition 1 2 and partition 2 3 can divide the pool body 1 into an output chamber 4, an intermediate chamber 5 and an input chamber 6. The intermediate chamber 5 is located between the output chamber 4 and the input chamber 6. Both sets of pressure rollers 7 are installed in the intermediate chamber 5.

[0038] Several output guide rollers 41 are installed in the output chamber 4, and the fabric sequentially wraps around each output guide roller 41. Several input guide rollers 61 are installed in the input chamber 6, and the fabric sequentially wraps around each input guide roller 61. During the wrapping process, the fabric forms a curved serpentine structure, which can extend the length of the fabric immersed in the reagent, especially in the reagent within the output chamber 4. After being squeezed multiple times by two sets of pressure rollers 7, the fabric will pass through the output chamber 4, continuously contacting and adhering to the reagent within the output chamber 4, thereby extending the contact time between the fabric and the reagent and increasing the amount of reagent adhering to the deeper layers of the fabric.

[0039] The reagent in pool 1 can flow between the three chambers. Specifically, a gap 21 is formed between partition 2 and the bottom of pool 1, and a gap 31 is formed between partition 3 and the bottom of pool 1. Both gaps are located approximately at the bottom of pool 1, which allows the chambers in pool 1 to communicate with each other and prevents suspended flocculent impurities in the chambers from contaminating the output side.

[0040] Reference Figure 4 As shown, the output chamber 4 is equipped with a reagent inlet 8, which is connected to the dyeing reagent inlet pipeline, enabling an input state within the output chamber 4. Meanwhile, the input chamber 6 is equipped with a reagent outlet 9, which is connected to the dyeing reagent outlet pipeline, allowing the reagent at outlet 9 to be discharged outwards, thus creating reagent flow. The reagent flow direction is roughly opposite to the fabric flow direction, ensuring that the reagent encountered by the fabric during its backward flow is relatively cleaner. This results in better dyeing effect on the subsequent fabric after adsorbing the dye reagent, and also reduces impurity adhesion to the output fabric.

[0041] A heater is installed inside pool 1. The heater can appropriately raise the temperature of the dyeing reagent inside pool 1 to meet the process requirements of different dyeing processes.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
