Description

Technical Field

[0001] This utility model relates to the field of composite fiber dyeing technology, and specifically to a composite fiber dyeing device. Background Technology

[0002] Composite fibers are made by separating two or more polymers through a special distribution plate and then forming them through a spinneret. Polyester-nylon composite microfiber not only has the good elasticity, shape retention, crispness and wrinkle-free properties of polyester, but also retains the advantages of nylon such as wear resistance, high strength, easy dyeing and moisture absorption. Polyester-nylon composite microfiber has a very low density but a very large specific surface area, which is usually several times or even dozens of times that of conventional fibers. As people's needs change, the color requirements of composite fibers also change, and dyeing composite fibers requires the use of dyeing machines.

[0003] Chinese Patent No. CN220318160U discloses a double-layer fiber fabric composite processing device, including a dyeing tank. First fixing plates are fixedly connected to the outer surfaces of both sides of the dyeing tank. A first gantry frame is fixedly connected to the top outer surfaces of the two first fixing plates. A threaded rod is threaded through the top outer surface of the first gantry frame. A knob is fixedly connected to the top outer surface of the threaded rod. An upper scraper is fixedly installed on the bottom outer surface of the first mounting plate, and a lower scraper is fixedly connected to the top outer surface of the second mounting plate. This double-layer fiber fabric composite processing device, by setting up upper and lower scrapers, in conjunction with threaded rods and knobs, solves the problem in existing technologies where, after dyeing, the dye adhering to the surface of the fiber fabric cannot be removed, leading to dye waste and poor subsequent drying efficiency.

[0004] However, the above technical solution has the following shortcomings: the dye on the fabric surface is scraped off by the cooperation between the upper and lower scrapers. If the distance between the upper and lower scrapers is too small, it will easily damage the fabric. If the distance between the upper and lower scrapers is too large, it will be difficult to scrape off the dye on the fabric surface. This not only easily leads to waste of dye, but also increases the workload of the subsequent drying unit. Utility Model Content

[0034] Example 2

[0035] like Figure 4 As shown, the present invention discloses a composite fiber dyeing device. Compared with Embodiment 1, this embodiment further discloses the structure of the bonding component. The bonding component includes a movable frame 431 and bonding springs 432. The movable frame 431 is slidably disposed in the support frame 2. One end of the driven shaft 46 is rotatably connected to the inner wall of the movable frame 431, and the other end of the driven shaft 46 passes through the movable frame 431 and the support frame 2 and extends to the outside of the support frame 2.

[0036] Example 3

[0037] like Figure 4As shown, the present invention discloses a composite fiber dyeing device. Compared with Embodiment 2, this embodiment further discloses the structure of the drive assembly.
