Description

Technical Field

[0001] This utility model relates to the field of wool processing technology, and in particular to a wool fiber reactive dyeing device. Background Technology

[0002] Wool fiber, as a natural protein fiber, is widely used in the textile industry due to its excellent properties such as softness, warmth, and good moisture absorption. However, the dyeing process of wool fiber is relatively complex. Its surface has a scaly structure, and there are many air gaps within the fiber. These characteristics make it difficult for dyes to penetrate evenly, easily leading to problems such as uneven dyeing and color differences. Traditional wool dyeing methods typically employ immersion or spray dyeing processes, but these methods often suffer from drawbacks such as low dye utilization, high energy consumption, and significant environmental pollution. Especially in the dyeing process with reactive dyes, it is difficult to effectively guarantee the dye fixation rate and uniformity.

[0003] Furthermore, existing dyeing equipment does not adequately exhaust air from wool fibers during the dyeing process, resulting in incomplete removal of air from the fiber gaps, which further affects dye penetration and fixation. Simultaneously, the temperature and pressure control during the dyeing process is not precise enough, easily causing fiber damage or unsatisfactory dyeing results. Therefore, developing a reactive dyeing device for wool fibers that can efficiently exhaust air, uniformly dye, and is environmentally friendly and energy-saving has become a pressing technical problem for the textile industry.

[0004] Therefore, it is essential to invent a device for dyeing wool fibers with reactive dyes. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a wool fiber reactive dyeing device, which solves the existing wool dyeing structures that still suffer from the inability to effectively and quickly penetrate the wool, resulting in ineffective dyeing and easy dispersion of dye and wool. The wool fiber reactive dyeing device includes a dyeing tank, support legs, a cover, a connecting seat, a lifting cable, an exhaust structure, a discharge port, and wool. The support legs are fixedly installed below the dyeing tank, and the cover is fixedly installed on top of the dyeing tank. The connecting seat is fixedly installed on top of the cover. The lifting cable is suspended above the connecting seat, and the exhaust structure is fixedly installed inside the cover. The discharge port is fixedly installed at the bottom of the dyeing tank. The wool is placed inside the dyeing tank.

[0006] The cap includes a cap body, an installation port, a sealing plate, an exhaust pipe, and a dye inlet pipe. The cap body is fixedly installed on the top of the dyeing tank, and the installation port is fixedly installed in the middle position above the cap body. The sealing plate is fixedly installed above the installation port, and the exhaust pipe is fixedly installed on the sealing plate. The dye inlet pipe is fixedly installed on the cap body.

[0007] The exhaust structure includes a mounting base, a hydraulic cylinder, a telescopic rod, a pressure plate, and a through-hole. The mounting base is fixedly installed inside the cover, and the hydraulic cylinder is fixedly installed inside the mounting base. The telescopic rod is slidably installed below the hydraulic cylinder, and the pressure plate is fixedly installed at the bottom end of the telescopic rod. The through-hole is opened inside the pressure plate.

[0008] The inner cover of the cap is a steel metal cap that seals the top of the dyeing tank. One end of the air extraction pipe is connected to an air pump. The air extraction pipe can extract air from inside the dyeing tank and also extract air from the gaps between the wool fibers. The dye inlet pipe is a steel metal pipe that can introduce dye into the interior of the dyeing tank.

[0009] The pressure plate inside the exhaust structure is a circular steel plate with several through holes. The pressure plate can move back and forth vertically inside the dyeing tank. The pressure plate can compress the wool and squeeze out the air inside.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The sealing cap of this utility model is used to seal the dyeing tank, preventing dye and wool leakage and ensuring the stability of the dyeing environment. It has an internal air extraction pipe that can be connected to an air pump to extract air from inside the tank and from the gaps between the wool fibers, allowing the dye to penetrate more quickly to the center of the wool, improving dyeing uniformity. Simultaneously, the dye inlet pipe on the cap introduces dye into the tank, ensuring efficient dye distribution. Furthermore, the cap also supports an exhaust structure, which compresses the wool fibers and expels air via a pressure plate, further optimizing the dyeing effect.

[0012] 2. The exhaust structure of this invention is designed to expel air from the gaps between wool fibers inside the dyeing tank, ensuring that the dye can penetrate the wool fibers evenly. It is driven by a hydraulic cylinder to extend a telescopic rod, which in turn moves a pressure plate vertically in a reciprocating motion, compressing the wool fibers and squeezing out the internal air. Simultaneously, the perforations on the pressure plate further promote air expulsion. This exhaust structure not only improves the uniformity and efficiency of dyeing but also reduces the interference of air on the dyeing effect, making it a key device for ensuring the quality of wool fiber dyeing.
