Technical Field
[0001] The utility model relates to the technical field of dyeing devices, in particular to a uniform dyeing vat for ammonia-polyurethane core-spun yarn. Background Art
[0002] In the field of textile printing and dyeing, ammonia-polyurethane core-spun yarn, as a fiber material with excellent elasticity and softness, is widely used in products such as clothing, shoes, hats, and luggage. With the increasing demand of consumers for the color diversity of textiles, as one of the important textile raw materials, ammonia-polyurethane core-spun yarn can be dyed to endow it with rich colors to meet the pursuit of colorful and fashionable textiles in the market. Through dyeing treatment, ammonia-polyurethane core-spun yarn can present more vivid and saturated colors, improving the visual effect of products.
[0003] The uniform dyeing vat for ammonia-polyurethane core-spun yarn is a comprehensive textile dyeing device integrating functions such as dyeing, color fixation, and cleaning. It adopts a specific structural design and process flow to ensure that ammonia-polyurethane core-spun yarn can uniformly absorb dyes during the dyeing process, achieving an ideal dyeing effect.
[0004] However, ammonia-polyurethane core-spun yarn is composed of multiple fibers, and there are differences in the dye absorption ability and dyeing speed of different fibers, resulting in easy occurrence of color difference and uneven dyeing during the dyeing process. Summary of the Utility Model
[0005] Based on this, the purpose of the utility model is to provide a uniform dyeing vat for ammonia-polyurethane core-spun yarn to solve the technical problem that ammonia-polyurethane core-spun yarn is composed of multiple fibers, and there are differences in the dye absorption ability and dyeing speed of different fibers, resulting in easy occurrence of color difference and uneven dyeing during the dyeing process.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A uniform dyeing vat for ammonia-polyurethane core-spun yarn, including a dyeing barrel, a color fixation barrel is fixedly connected to the top of the dyeing barrel, a top plate is arranged on the top of the color fixation barrel, multiple groups of support rods are fixedly installed on the top of the top plate, a fixing plate is connected to the top of the support rods, multiple groups of electric telescopic rods are installed on the fixing plate, the output end of the electric telescopic rod is fixedly connected to a movable plate, multiple groups of connecting rods are arranged at the bottom of the movable plate, an inner barrel is fixedly connected to the bottom of the connecting rod, a motor is arranged on the top of the movable plate, a stirring structure is fixedly connected to the output end of the motor, a dyeing solution is filled in the dyeing barrel, a gas guide ring is arranged on the outside of the color fixation barrel, multiple groups of air guide pipes are snap-connected in the color fixation barrel, multiple groups of the air guide pipes are fixed inside the gas guide ring, multiple groups of nozzles are arranged on the inner side of the air guide pipe, an air inlet pipe is arranged on the outside of the gas guide ring, and multiple groups of filter holes for the use of dyeing solution and steam are opened on the inner barrel.
[0007] By adopting the above technical solution, during use, by driving the electric telescopic rod, the movable plate moves downward until the connecting rod drives the inner barrel into the dyeing barrel. After the core-spun yarn is soaked in the dyeing barrel, the movable plate and the connecting rod are driven upward by driving the electric telescopic rod, so that the inner barrel moves into the fixing barrel. Then, steam is efficiently transported into the fixing barrel through the air guide ring and the air guide pipe, and the nozzle is responsible for evenly spraying the steam on the fabric or fiber. This design ensures that the steam can fully contact and penetrate into the core-spun yarn. The even spraying of the steam accelerates the fixing chemical reaction, thereby shortening the fixing time and improving the production efficiency. With this structure, during the dyeing process of the core-spun yarn, the practice of taking it out of the dye liquor several times, performing steam treatment with high-temperature steam, and then re-immersing it in the dye liquor for dyeing is repeated. The electric telescopic rod drives the inner barrel to move up and down through the movable plate. The dyeing barrel is specifically used for the penetration and dyeing process of the dye, while the fixing barrel is used for subsequent fixing treatment. The high-temperature steam treatment can make the fibers of the core-spun yarn expand, increasing the gaps between the fibers, which is beneficial for the dye to better penetrate into the fiber interior, thereby improving the uniformity of dyeing. The multiple groups of filter holes opened on the inner barrel allow the dye liquor and steam to pass through. The design of these holes enables the dye liquor and steam to more easily penetrate into the core-spun yarn interior, enhancing the dyeing and fixing effects. The filter holes also improve the air permeability of the inner barrel, helping to reduce the moisture accumulation generated by the fabric or fiber during the dyeing and fixing processes and maintaining its dry state, thereby improving the dyeing quality and enhancing the practicality and flexibility of the entire ammonia-polyurethane core-spun yarn uniform dyeing vat.
[0008] The present utility model is further configured such that the stirring structure includes a transmission rod and multiple groups of stirring rods. The transmission rod is fixedly connected to the output end of the motor, and multiple groups of the stirring rods are fixed to the outer side of the transmission rod.
[0009] By adopting the above technical solution, the mutual cooperation between the set transmission rod and the stirring rods enables the core-spun yarn to be fully stirred in the dyeing barrel. The fixed connection between the transmission rod and the output end of the motor ensures that the power output by the motor can be directly transmitted to the transmission rod, reducing the loss during the power transmission process, thereby improving the stirring efficiency.
[0010] The present utility model is further configured such that an installation groove for cooperating with the air guide pipe is opened on the outer side of the fixing barrel, and fixing blocks are fixedly connected to the outer side of the fixing barrel in a symmetrical structure. The air guide ring is fixedly connected to the fixing blocks.
[0011] By adopting the above technical solution, the provided installation groove is conducive to stably fixing the air guide pipe. The tight connection between the air guide ring and the fixing block helps maintain the smoothness of the air guide pipe, ensuring that the steam required during the color fixation process can be stably and efficiently transported into the color fixation barrel, thereby improving the color fixation effect. Moreover, the fixed connection between the air guide ring and the fixing block makes the installation and disassembly process of the air guide pipe simpler and faster, reducing the operation difficulty and time cost.
[0012] The present utility model is further configured such that a liquid inlet pipe is provided on one side of the dyeing barrel, and a drain pipe for cooperating with the liquid inlet pipe is provided at the bottom of the dyeing barrel.
[0013] By adopting the above technical solution, the mutual cooperation between the provided liquid inlet pipe and the drain pipe is conducive to flexibly injecting the dye into the dyeing barrel for dyeing the core-spun yarn. When the dye solution needs to be replaced, the waste liquid can be discharged through the drain pipe, so as to flexibly replace the dye solution in the dyeing barrel.
[0014] The present utility model is further configured such that a plurality of support legs are fixedly installed at the bottom of the dyeing barrel, and rubber pads are provided at the bottoms of the support legs.
[0015] By adopting the above technical solution, the provided support legs can stand the entire dyeing device on the ground for use, and the rubber pads at the bottoms of the support legs are beneficial to maintaining the stability of the dyeing device.
[0016] The present utility model is further configured such that a card slot for cooperating with the color fixation barrel and the air guide pipe is provided at the bottom of the top plate.
[0017] By adopting the above technical solution, the provided card slot is conducive to enabling the top plate to be flexibly connected and fixed to the top of the color fixation barrel.
[0018] The present utility model is further configured such that a sealing ring is provided in the card slot.
[0019] By adopting the above technical solution, the sealing ring provided in the card slot is beneficial to maintaining the sealing performance inside the dyeing barrel and the color fixation barrel, so that the core-spun yarn can be better dyed in the dyeing device.
[0020] In summary, the present utility model mainly has the following beneficial effects:
[0021] 1. The utility model controls the up-and-down movement of the movable plate and the inner barrel through an electric telescopic rod, realizing the conversion of the core-spun yarn between the dyeing barrel and the color-fixing barrel. The dyeing barrel is used for dye penetration, and the color-fixing barrel evenly sprays high-temperature steam on the fabric through an air guide ring, an air guide pipe and a nozzle, accelerating the color-fixing reaction, shortening the color-fixing time and improving the production efficiency. In this process, the core-spun yarn undergoes multiple dye liquor immersions and steam treatments to optimize the dyeing effect. The multi-group filter hole design of the inner barrel enhances the permeability of the dye liquor and steam, improves the dyeing uniformity and color-fixing quality, and at the same time promotes the discharge of moisture, keeps the fabric dry, and improves the practicability and flexibility of the core-spun yarn dyeing vat;

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.
[0030] Next, the embodiments of the present utility model will be described according to its overall structure.

The output end of the electric telescopic rod 13 is fixedly connected to a movable plate 14. A plurality of connecting rods 18 are arranged at the bottom of the movable plate 14. The bottom of the connecting rod 18 is fixedly connected to an inner barrel 22. A motor 15 is arranged at the top of the movable plate 14. The output end of the motor 15 is fixedly connected to a stirring structure. The dyeing barrel 1 is filled with dye liquor. A gas guide ring 7 is arranged outside the fixing barrel 2.

A plurality of nozzles 16 are arranged on the inner side of the gas guide pipe 8. An air inlet pipe 9 is arranged outside the gas guide ring 7. A plurality of filter holes for the use of dye liquor and steam are opened on the inner barrel 22.
[0032] During use, by driving the electric telescopic rod 13, the movable plate 14 moves downward until the connecting rod 18 drives the inner barrel 22 into the dyeing barrel 1. After the core-spun yarn is soaked in the dyeing barrel 1, then by driving the electric telescopic rod 13, the movable plate 14 and the connecting rod 18 move upward, so that the inner barrel 22 moves into the fixing barrel 2. Then, the steam is efficiently conveyed into the fixing barrel 2 through the gas guide ring 7 and the gas guide pipes 8, and the nozzles 16 are responsible for evenly spraying the steam on the fabric or fiber. This design ensures that the steam can fully contact and penetrate into the core-spun yarn. The even spraying of the steam accelerates the fixing chemical reaction, thereby shortening the fixing time and improving the production efficiency. With this structure, during the dyeing process of the core-spun yarn, repeat the operation of taking out from the dye liquor, performing steam treatment with high-temperature steam, and then re-immersing in the dye liquor for dyeing several times. The electric telescopic rod 13 drives the inner barrel 22 to move up and down through the movable plate 14. The dyeing barrel 1 is specifically used for the penetration and dyeing process of the dye, while the fixing barrel 2 is used for the subsequent fixing treatment. The high-temperature steam treatment can make the fibers of the core-spun yarn expand, increasing the gaps between the fibers, which is beneficial to the better penetration of the dye into the fiber interior, thereby improving the uniformity of dyeing. The plurality of filter holes opened on the inner barrel 22 allow the dye liquor and steam to pass through. The design of these holes enables the dye liquor and steam to more easily penetrate into the core-spun yarn, enhancing the dyeing and fixing effects. The filter holes also improve the air permeability of the inner barrel 22, helping to reduce the moisture accumulation generated by the fabric or fiber during the dyeing and fixing processes and keeping it in a dry state, thereby improving the dyeing quality and enhancing the practicality and flexibility of the entire uniform dyeing vat for spandex core-spun yarn.
[0033] The further cooperation between the transmission rod 20 and the stirring rod 21 can ensure that the core-spun yarn can be fully stirred in the dyeing barrel 1. The fixed connection between the transmission rod 20 and the output end of the motor 15 ensures that the power output by the motor 15 can be directly transmitted to the transmission rod 20, reducing the loss during the power transmission process and thus improving the stirring efficiency. The provided installation groove 17 is beneficial for stably fixing the air guide pipe 8. The tight connection between the air guide ring 7 and the fixing block 6 helps to maintain the smoothness of the air guide pipe 8, ensuring that the steam required during the color fixation process can be stably and efficiently delivered into the color fixation barrel 2, thereby improving the color fixation effect. Moreover, the fixed connection between the air guide ring 7 and the fixing block 6 makes the installation and disassembly process of the air guide pipe 8 more simple and fast, reducing the operation difficulty and time cost.
[0034] In this embodiment, the cooperation between the liquid inlet pipe 5 and the liquid discharge pipe 4 is beneficial for flexibly injecting the dyeing solution into the dyeing barrel 1 to cooperate with the core-spun yarn for dyeing. When the dyeing solution needs to be replaced, the waste liquid can be discharged through the liquid discharge pipe 4 to facilitate the flexible replacement of the dyeing solution in the dyeing barrel 1. The provided support legs 3 can stand the entire dyeing device on the ground for use, and the rubber pads at the bottom of the support legs 3 are beneficial for maintaining the stability of the dyeing device.
