The second dyeing component includes a second dyeing box, a third pressure roller, and a fourth pressure roller.

[0004] The fabric dyeing device described in the above patent has problems such as uneven dye temperature and inconsistent fabric heating during the dyeing process. This leads to uneven adhesion of dye molecules to the fabric fibers, which affects the dyeing effect of the fabric and causes the fabric to have uneven dyeing depth. Therefore, a dyeing device that can dye fabric evenly is needed. Utility Model Content

[0005] The main objective of this invention is to provide a dyeing apparatus for uniform fabric dyeing, which can effectively solve the problems mentioned above.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A fabric dyeing apparatus for uniform dyeing includes a heating chamber. Four rotating rollers are rotatably mounted on the front and right walls of the heating chamber. A smoke generator is fixedly mounted on the middle of the front and rear ends of the heating chamber. A high-pressure pump is fixedly mounted on the lower middle side of the rear end of the heating chamber. Guide rollers are fixedly mounted on the upper left and right sides of the front and rear ends of the heating chamber. A steam device is fixedly mounted on the middle of the upper end of the heating chamber. A stirring device is rotatably mounted on the left and right sides of the front and rear walls of the heating chamber.

[0008] Preferably, the steam device includes two fixed brackets, which are respectively fixedly installed on the front and rear sides of the upper middle part of the heating box. A steam outlet pipe is fixedly installed on both fixed brackets. A plurality of steam outlet holes are opened on the upper part of the outer surface of the steam outlet pipe. A heating pipe is fixedly installed at both the front and rear ends of the steam outlet pipe.

[0009] Preferably, the two heating tubes are respectively connected to the two smoke generator outlets.

[0010] Preferably, the stirring device includes a gas supply pipe and two transmission rods. The gas supply pipe is installed at the output end of the high-pressure pump. The two transmission rods are rotatably installed on the left and right sides of the front and rear walls of the heating box, respectively. Three stirring blades are fixedly installed on the outer surface of each of the two transmission rods. A drive mechanism is installed on the rear part of the inner surface of the two transmission rods and the gas outlets on both sides of the gas supply pipe.

[0011] Preferably, the two transmission rods are respectively connected to three stirring blades, and each of the three stirring blades has several air outlet holes on one side.

[0012] Preferably, the drive mechanism includes an air intake plate and an air intake ring. The air intake plate is fixedly installed at the air outlet on one side of the air supply pipe.

[0013] Preferably, the intake ring is connected to the transmission rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model, through its designed stirring device, can effectively agitate the dye in the heating chamber, making the temperature distribution of the dye more uniform during the heating process and avoiding local overheating. While agitating, the stirring device can also aerate the dye. High-pressure gas flows into the dye through the aeration holes on the stirring blades, causing a large number of bubbles to be generated in the dye. As these bubbles rise, they will cause the dye to tumble, promoting the mixing of the dye and the uniformity of color distribution, making the dyeing of fabric more uniform.

[0016] 2. This device can generate high-temperature steam through its designed steam device, and evenly transfer it to the fabric through the steam outlet. When the steam comes into contact with the fabric, it liquefies and releases a large amount of latent heat. The heat can quickly and evenly penetrate to all parts of the fabric, avoiding uneven dyeing due to local temperature differences, making the fabric dyed more evenly and with brighter colors.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Example 1, as Figure 1 , Figure 2 and Figure 3 As shown, a dyeing apparatus for uniform fabric dyeing includes a heating box 1. Four rotating rollers 7 are rotatably installed on the front and right walls of the heating box 1. Smoke generators 2 are fixedly installed at the front and rear middle of the heating box 1. A high-pressure pump 6 is fixedly installed on the lower middle side of the rear end of the heating box 1. Guide rollers 4 are fixedly installed on the upper left and right sides of the front and rear ends of the heating box 1. A steam device 3 is fixedly installed at the upper middle of the heating box 1. A stirring device 5 is rotatably installed on the left and right sides of the front and rear walls of the heating box 1.

[0028] This device is powered by 380V DC. The heating box 1 in this device can be a constant temperature water tank of the existing technology model DISOFOO DH-W420.

[0029] Before implementing this device, firstly:

[0030] Place the unwinding roller with the fabric wound on it on the left side of the device, and then place the rewinding roller that pulls the fabric on the right side of the heating box 1. The operator then arranges the fabric according to... Figure 3As shown, the dye is wound around the guide roller 4, rotating roller 7 and steam device 3. Then, the worker pours the dye into the heating box 1 and starts the heating box 1 to heat the dye. The heating provides energy to the dye molecules, which increases their movement speed. The dye molecules can diffuse more actively into the fabric fibers, thereby improving the dyeing efficiency and uniformity.

[0031] The staff can adjust the temperature of the dye inside the heating box 1 to make the temperature of the dye suitable for the current fabric. The control method is a conventional operation in the existing technology, and will not be described in detail in this article.

[0032] In the above process, the staff will start the high-pressure pump 6, the steam device 3 and the smoke generator 2. When the high-pressure pump 6 is running, it will drive the stirring device 5 to rotate, so that the dye in the heating box 1 is stirred by the rotation of the stirring device 5, making the dye more uniformly mixed in the heating box 1 and avoiding local overheating. At the same time, the stirring device 5 can also aerate the dye, so that the color of the dye can be evenly distributed and avoid local color being too dark.

[0033] In the above process, when the smoke generator 2 moves, it delivers water mist into the steam device 3. The steam device 3 then heats the delivered water mist and transfers the heated steam to the fabric wrapped around the surface. When the steam comes into contact with the fabric, it releases a large amount of latent heat through liquefaction. The heat can quickly and evenly penetrate into all parts of the fabric, avoiding uneven dyeing due to local temperature differences and making the fabric dyed more evenly.

[0034] In the above, the heating box 1 is divided into left and right compartments, so that the fabric first passes through the left compartment and is heated by the steam generated by the steam device 3, and then enters the right compartment of the heating box 1 for secondary dyeing, so that the dyeing is more uniform.

[0035] In the above, the guide roller 4 is used to guide the fabric, and the external take-up roller stretches the fabric so that it can proceed to the next process.

[0036] In Example 2, further, in order to achieve the purpose of applying steam to the fabric using the steam device 3, see [reference needed]. Figure 4 The steam device 3 includes two fixed brackets 33, which are respectively fixedly installed on the front and rear sides of the upper middle part of the heating box 1. A steam outlet pipe 31 is fixedly installed on both fixed brackets 33. Several steam outlet holes 32 are opened on the upper part of the outer surface of the steam outlet pipe 31. A heating pipe 34 is fixedly installed at both the front and rear ends of the steam outlet pipe 31.

[0037] Furthermore, the two heating tubes 34 are respectively connected to the air outlets of the two smoke generators 2.

[0038] In the above process, the smoke generator 2 and the heating tube 34 are started to operate. The smoke generator 2 can be a water mist generator of the existing technology model JC-YW-6. The smoke generator 2 then transmits water mist to the heating tube 34 through the output end, so that the heating tube 34 heats the water mist. The heating tube 34 can be a heating tube of the existing technology model TS CC.T22. The water mist heated by the heating tube 34 will turn into steam and then enter the steam outlet pipe 31. The steam will be transmitted to the fabric through the steam outlet hole 32 on the steam outlet pipe 31, heating the fabric and making the dyeing on the fabric more uniform.

[0039] Furthermore, in order to achieve the purpose of stirring and aerating the dye in the heating box 1 by the stirring device 5, refer to... Figures 5-8 The stirring device 5 includes a gas supply pipe 54 and two transmission rods 52. The gas supply pipe 54 is installed at the output end of the high-pressure pump 6. The two transmission rods 52 are rotatably installed on the left and right sides of the front and rear walls of the heating box 1, respectively. Three stirring blades 51 are fixedly installed on the outer surface of each of the two transmission rods 52. The drive mechanism 53 is installed on the rear part of the inner surface of the two transmission rods 52 and the gas outlets on both sides of the gas supply pipe 54.

[0040] Furthermore, the two transmission rods 52 are respectively connected to the three stirring blades 51, and each of the three stirring blades 51 has several air outlet holes on one side.

[0041] Furthermore, the drive mechanism 53 includes an air intake plate 531 and an air intake ring 537. The air intake plate 531 is fixedly installed at the air outlet on one side of the air supply pipe 54. Three oblique flow holes 532 are opened on the outer ring of the front end of the air intake plate 531. A rotating blade 533 is rotatably installed in the middle of the front end of the air intake plate 531. A rotating plate 534 is fixedly installed at the front end of the rotating blade 533. The air intake ring 537 is fixedly installed on the rear part of the inner surface of the transmission rod 52. A sealing plate 536 is slidably installed on the inner surface of the air intake ring 537. A compression spring 535 is installed on the end of the sealing plate 536 and the rotating plate 534 that are close to each other.

[0042] Furthermore, the intake ring 537 is connected to the transmission rod 52.

[0043] In the above process, the high-pressure pump 6 is started to operate, which inputs high-pressure gas into the gas delivery pipe 54. The gas then enters the position of the air inlet plate 531 through the gas delivery pipe 54. The air inlet plate 531 is designed with oblique flow holes 532 on its surface, which allows the gas to be delivered forward at an oblique angle and come into contact with the rotating blade 533. Because the gas becomes oblique flow through the oblique flow holes 532, the gas pushes the rotating blade 533 to rotate after contacting it. When the rotating blade 533 rotates, it drives the rotating plate 534 to rotate as well. The rotating plate 534 then transmits the power to the transmission rod 52, which drives the stirring blade 51 to rotate, so that the stirring blade 51 agitates the dye and makes the dye heated more evenly by the heating box 1.

[0044] In the above description, after the gas enters the transmission rod 52 through the inclined flow hole 532, it continues to flow forward through the through hole on the rotating plate 534. At this time, the high-pressure gas pushes the sealing plate 536 to slide forward in the inner cavity of the air intake ring 537, causing the sealing plate 536 to slide out of the air intake ring 537 and release the sealing plate 536 from the air intake ring 537. Then the gas will enter the depth of the transmission rod 52. Through the design of the transmission rod 52 communicating with the stirring blade 51, the gas will enter the stirring blade 51. Then the gas will flow out from the aeration hole on the stirring blade 51 into the dye, causing bubbles to be generated in the dye, thus achieving a more uniform color distribution of the dye.

[0045] It should be noted that the specific installation method, circuit connection method, and control method of the smoke generator 2, heating tube 34, and high-pressure pump 6 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
