Description

Technical Field

[0001] This utility model relates to the technical field of fabric dehydration equipment, and more specifically to a dehydration equipment for fabric dyeing. Background Technology

[0002] In the fabric dyeing process, the dehydration stage is crucial. Fabric dyeing is the process of fixing dyes onto the fabric through chemical methods or physical-mechanical actions, resulting in a uniform and durable color. This process not only endows the fabric with rich colors and aesthetic appeal but also enhances its added value and market competitiveness. However, dyed fabrics often contain a large amount of moisture, which, if not removed promptly, will have many adverse effects on subsequent processing and use. Therefore, dehydration treatment is necessary after fabric dyeing.

[0003] As shown in the prior art published in CN220503430U, although this prior art achieves dyeing by setting up a dyeing box and then moving the warp-knitted fabric within the dyeing box under external force, and simultaneously squeezing out excess dye from the warp-knitted fabric under the action of the water-pressing component, which is both time-saving and labor-saving and avoids dye waste, this technical solution still leaves moisture on the fabric during the squeezing and dehydration process, and cannot effectively dehydrate the fabric, resulting in certain limitations of this technical solution. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides a dehydration device for fabric dyeing. Air delivered to the heating chamber by a first fan is heated by an electric heating plate and then transported to the interior of hollow tubes via a connecting pipe for further heating. Because the multiple hollow tubes are wavy, they can achieve double-sided contact with the fabric and extend the fabric's travel path, allowing for full contact between the fabric and the hot air. Furthermore, the connection between the air vents and the support frame allows the hot air in the heating chamber to circulate into the support frame, thereby heating the temperature inside the support frame and improving the drying and dehydration efficiency of the fabric, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dehydration device for fabric dyeing, comprising a dyeing box for fabric dyeing, and a drying component for fabric dehydration provided on the front side of the dyeing box;

[0006] The drying component includes a support frame installed on the front side of the top of the dyeing box. The support frame has multiple hollow tubes arranged in a wave-like pattern inside, and each hollow tube has a connecting tube installed at both ends through a bearing.

[0007] A heating box is embedded inside the top of the support frame, and the end of the connecting pipe away from the hollow tube passes through the support frame and is fixedly connected to the heating box.

[0008] The heating box has two spaced-apart electric heating plates installed inside the top of the heating box, and multiple spaced-apart air holes opened inside the bottom of the heating box. The top of the heating box is fixedly connected to an air duct, and a first fan is installed inside the air duct.

[0009] In a preferred embodiment, the bottom end of the support frame is fixedly connected to an output pipe, and a second fan is installed inside the top end of the output pipe.

[0010] The output tube extends from the end away from the support frame to the rear side of the dyeing box, and the top of the rear end of the output tube is fixedly connected to the box body, and the top of the box body has multiple output holes distributed at intervals.

[0011] In a preferred embodiment, the dyeing box has an inlet and an outlet on the front and rear sides of its top, respectively. The outlet is located in front of the inlet and is connected to the support frame.

[0012] The dyeing box has a feed pipe and a discharge pipe fixedly connected to its top and bottom, respectively, with the feed pipe located at the top of the discharge pipe.

[0013] In a preferred embodiment, multiple guide rollers are movably mounted inside the dyeing box via a rotating shaft. The multiple guide rollers are distributed in a wave-like pattern, and an extrusion element is provided on the top of the guide rollers near the discharge port.

[0014] In a preferred embodiment, the extrusion member includes two electric push rods mounted on the top front end of the dyeing box, and the top of the two electric push rods is equipped with the same movable plate. The bottom of the movable plate is equipped with two spaced-apart pillars, the bottom ends of which penetrate the dyeing box and extend into the interior of the dyeing box.

[0015] The two support columns are equipped with the same extrusion roller at their bottom ends, and both ends of the extrusion roller are fitted with fixed rings that are movably connected by bearings. The top of the fixed rings is equipped with a telescopic rod for connecting the support columns, and the bottom end of the telescopic rod is fitted with a spring.

[0016] In a preferred embodiment, fixed supports are installed at both the front and rear ends of the dyeing box, and the end of the fixed support away from the dyeing box is sleeved on the outside of the output pipe.

[0017] In a preferred embodiment, a dustproof net is installed inside the top of the duct, and the dustproof net is located on the top of the first fan.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] 1. The air delivered to the heating box by the first fan is heated by the electric heating plate, and then delivered to the hollow tube through the connecting pipe for heating. Because the multiple hollow tubes are wavy, they can achieve double-sided contact with the fabric and extend the running path of the fabric, so that the fabric can fully contact the hot air. The hot air in the heating box can also flow into the support frame through the air holes, thereby heating the temperature inside the support frame and improving the drying and dehydration efficiency of the fabric.

[0020] 2. The water vapor in the support frame is transported to the inside of the box through the output pipe by the second fan, and then discharged through the output hole on the box. In this way, the high-temperature water vapor can be used to humidify the fabric that has not yet been transported to the dyeing box, so that the dye can come into full contact with the fabric in the subsequent dyeing process, allowing the dye to penetrate into the fabric better and improve the dyeing effect of the fabric.

[0027] 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.

[0028] Refer to the instruction manual appendix Figure 1-5 This utility model provides a dehydration device for fabric dyeing, including a dyeing box 1 for dyeing fabric. The dyeing box 1 has an inlet 14 and an outlet 15 on the front and rear sides of its top. The outlet 15 is located in front of the inlet 14 and is connected to the support frame 2. The top and bottom of the dyeing box 1 are respectively fixedly connected to an inlet pipe 16 and an outlet pipe 17. The inlet pipe 16 is located at the top of the outlet pipe 17. The fabric is transported into the dyeing box 1 through the inlet 14 for dyeing treatment, and then sent to the subsequent drying unit through the outlet 15 for dehydration treatment. At the same time, the dye is replenished and discharged through the inlet pipe 16 and the outlet pipe 17.

[0029] At the same time, to improve the dyeing effect of the fabric, it is necessary to ensure that the fabric and dye are in full contact, such as... Figure 2 As shown, multiple guide rollers 18 are movably mounted inside the dyeing box 1 via a rotating shaft. These guide rollers 18 are arranged in a wave-like pattern. An extrusion element is located at the top of the guide roller 18 near the discharge port 15. The multiple guide rollers 18 guide the fabric into the dyeing box 1, ensuring sufficient contact between the fabric and the dye. The extrusion element includes two electric push rods 19 mounted at the top front of the dyeing box 1, with a single movable plate 20 mounted on top of the two electric push rods 19. Two spaced-apart support pillars 21 are mounted at the bottom of the movable plate 20, with the bottom ends of the support pillars 21 penetrating the dyeing box 1 and extending into it. Inside; the bottom ends of the two support columns 21 are provided with the same squeezing roller 22, and both ends of the squeezing roller 22 are fitted with fixed rings 27 that are movably connected by bearings. The top of the fixed rings 27 is equipped with a telescopic rod 23 for connecting the support column 21. The bottom end of the telescopic rod 23 is fitted with a spring 24, so that the extension and retraction of the electric push rod 19 can drive the support column 21 on the movable plate 20 to move down and make the squeezing roller 22 on the support column 21 contact the fabric. At the same time, by means of the squeezing force of the spring 24, the squeezing roller 22 can make full contact with the fabric, thereby squeezing out the water in the fabric and realizing the initial dehydration of the fabric.

[0030] like Figure 1 , 2As shown in Figures 4 and 5, the front side of the dyeing box 1 is provided with a drying component for fabric dehydration; the drying component includes a support frame 2 installed on the front side of the top of the dyeing box 1, the support frame 2 has multiple hollow tubes 3 arranged in a wave-like pattern inside, and each hollow tube 3 has a connecting pipe 4 installed at both ends through a bearing; a heating box 5 is embedded inside the top of the support frame 2, and the end of the connecting pipe 4 away from the hollow tube 3 passes through the support frame 2 and is fixedly connected to the heating box 5; two spaced electric heating plates 6 are installed inside the top of the heating box 5, multiple spaced air holes 7 are opened inside the bottom of the heating box 5, and an air duct 8 is fixedly connected to the top of the heating box 5, and a first fan 9 is installed inside the air duct 8.

[0031] In use, the first fan 9 delivers air through the air duct 8 to the interior of the heating box 5, and then the electric heating plate 6 heats the air inside the heating box 5, raising the air temperature. Due to the fluidity and heat transfer properties of air, hot air can flow through the connecting pipe 4 into the hollow tube 3 under the action of the first fan 9. When the hot air flows inside the hollow tube 3, it transfers heat to the hollow tube 3, raising its temperature. This allows for the drying and dehydration of the fabric. The multiple hollow tubes 3, arranged in a wavy pattern, can perform double-sided drying and dehydration of the fabric and extend the fabric's travel path, ensuring full contact between the fabric and the hot air, thereby improving dehydration efficiency. Simultaneously, through the connection between the air vent 7 and the support frame 2, hot air from the heating box 5 can also flow into the support frame 2, thereby heating the temperature inside the support frame 2 and improving the drying and dehydration efficiency of the fabric. Since a dustproof net 26 is installed inside the top of the air duct 8 and is located on top of the first fan 9, the dustproof net 26 can block dust in the air, thus preventing dust and other impurities from entering the support frame 2 and the hollow tube 3 and causing pollution.

[0032] At the same time, to prevent the water vapor released during fabric dehydration from condensing back onto the fabric, it is necessary to remove the water vapor promptly, such as... Figure 1 and 2As shown, the bottom end of the support frame 2 is fixedly connected to an output pipe 10, and a second fan 11 is installed inside the top end of the output pipe 10. The end of the output pipe 10 away from the support frame 2 extends to the rear side of the dyeing box 1, and the top of the rear end of the output pipe 10 is fixedly connected to a box body 12. The top of the box body 12 has multiple spaced output holes 13. The water vapor in the support frame 2 is transported to the inside of the box body 12 through the output pipe 10 by the second fan 11, and then discharged through the output holes 13 on the box body 12. In this way, the fabric that has not yet been transported to the dyeing box 1 can be humidified with high-temperature water vapor, so that the dye can fully contact the dye in the subsequent dyeing process, and the dye can better penetrate into the fabric, thereby improving the dyeing effect of the fabric. Furthermore, the dyeing box 1 is equipped with fixed brackets 25 at both the front and rear ends, and the end of the fixed bracket 25 away from the dyeing box 1 is sleeved on the outside of the output pipe 10. Thus, the fixed brackets 25 can support and fix the output pipe 10, thereby ensuring the stability of the output pipe 10 and preventing the output pipe 10 from shaking.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
