Description

Technical Field

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

[0002] A spandex fiber dyeing device is a machine specifically designed for dyeing spandex fibers. It uses a specific process and apparatus to evenly apply dye to the spandex fibers, achieving fiber coloring. A search reveals that Chinese Patent Publication No. CN212895395U discloses a dyeing device for cotton-nylon-spandex fabrics. This device utilizes a combination of ropes and springs. The spring's elasticity causes the connecting plate to press downwards, resulting in deeper immersion of the yarn in the dyeing agent. This makes the yarn more taut during threading, leading to more even dyeing and higher dyeing quality. However, this device cannot achieve rapid dye penetration into the yarn simply by soaking, requiring a prolonged soaking time to fully dye the fibers. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a device for dyeing spandex fibers, which solves the problem mentioned in the background art that existing devices cannot allow dye to quickly penetrate into the yarn through soaking, thus requiring a long soaking time to fully dye the fibers.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a device for dyeing spandex fibers, comprising a water tank, a pressure assembly, and a tension adjustment mechanism. The water tank is filled with dye, and a spandex fiber cloth is placed inside the water tank, passing through the pressure assembly. Two pressure assemblies are provided, and a nozzle is provided between the two pressure assemblies. The nozzle is connected to a water pump via a connecting pipe, and the input end of the water pump is connected to the inside of the water tank via a pipe. A tension adjustment mechanism is provided on one side of the nozzle, and a drain outlet is provided on the outside of the water tank.

[0005] Preferably, the pressure assembly includes a second column, one end of which is welded to the bottom of the water tank, and the second column is rotatably connected to both ends of the support roller. A pressure roller is provided above the support roller, and both ends of the pressure roller are rotatably connected to a second slider. The second slider is slidably connected to the inside of the second column, and the top of the second slider is rotatably connected to the bottom end of the second threaded rod. The outer wall of the second threaded rod is threadedly connected to the top end of the second column. By rotating the second threaded rod, the second threaded rod can drive the second slider to move downward, thereby driving the pressure roller to move downward, so that the pressure roller can adjust the pressure on the spandex fiber cloth.

[0006] Preferably, the outer walls of both the pressure roller and the support roller are made of sponge material, and the pressure roller and the support roller are tightly fitted together. During compression, the dye inside the sponge can be squeezed into the spandex fiber cloth by external force, thereby enabling the dye to quickly penetrate into the spandex fiber cloth.

[0007] Preferably, the tension adjustment mechanism includes a first column, the bottom of which is welded to the bottom of the water tank. The inside of the first column is slidably connected to a first slider. The first slider is rotatably connected to the end of the tension roller, and the top of the first slider is rotatably connected to the bottom end of a first threaded rod. The outer wall of the first threaded rod is threadedly connected to the top end of the first column. When both ends of the spandex fiber cloth are fixed in the fabric feeding and taking-up equipment, the downward movement of the tension roller will increase the tension of the spandex fiber cloth, thereby increasing the internal voids of the spandex fiber cloth, making it easier for the dye to penetrate into the interior.

[0008] Preferably, the nozzle outlet is flat and the nozzle is located above the spandex fiber cloth. The dye is sprayed at high pressure onto the surface of the spandex fiber cloth through the nozzle, which helps to further promote the dye penetration into the interior of the spandex fiber cloth.

[0009] This invention provides a device for dyeing spandex fibers. It has the following beneficial effects:

[0010] (1) The device for dyeing spandex fibers, when the device is in use, the spandex fiber cloth is soaked in the dye inside the water tank. Under the action of the external traction device, the spandex fiber cloth is conveyed between the pressure roller and the support roller. The pressure roller and the support roller will squeeze the spandex fiber cloth between them. Through the sponge material outside the pressure roller and the support roller, the dye inside the sponge can be squeezed into the interior of the spandex fiber cloth by external force during the squeezing, so that the dye can quickly penetrate into the interior of the spandex fiber cloth, thereby improving the dyeing efficiency.

[0011] (2) The equipment for dyeing spandex fibers can drive the first slider to move downward while rotating the first threaded rod, thereby enabling the first slider to drive the tension roller to move downward. When the two ends of the spandex fiber cloth are fixed in the cloth feeding and taking-up equipment, the downward movement of the tension roller will increase the tension of the spandex fiber cloth, thereby increasing the gap inside the spandex fiber cloth, making it easier for the dye to penetrate into the interior.

[0012] This solves the problem that existing devices cannot allow dye to quickly penetrate into the yarn through soaking alone, thus requiring a long soaking time to fully dye the fibers. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1:

[0020] Please see Figure 1-4This utility model provides a technical solution: a device for dyeing spandex fibers, including a water tank 1, a pressure assembly 3, and a tension adjusting mechanism 8. The water tank 1 is filled with dye, and a spandex fiber cloth 2 is placed inside the water tank 1, passing through the pressure assembly 3. There are two pressure assemblies 3, and a nozzle 4 is placed between the two pressure assemblies 3. The nozzle 4 is connected to a water pump 5 through a connecting pipe 6. The input end of the water pump 5 is connected to the inside of the water tank 1 through a pipe. A tension adjusting mechanism 8 is provided on one side of the nozzle 4. A drain outlet 7 is provided on the side; the pressure assembly 3 includes a second column 301, one end of which is welded to the bottom of the water tank 1, and the second column 301 is rotatably connected to both ends of the support roller 302. A pressure roller 303 is provided above the support roller 302, and both ends of the pressure roller 303 are rotatably connected to the second slider 305. The second slider 305 is slidably connected to the inside of the second column 301, and the top of the second slider 305 is rotatably connected to one end of the bottom of the second threaded rod 304. The outer wall of the second threaded rod 304 is connected to the top of the second column 301. One end is threaded. By rotating the second threaded rod, the second threaded rod can drive the second slider downward, which in turn drives the pressure roller downward, allowing the pressure roller to adjust the pressure applied to the spandex fiber cloth. The outer walls of both the pressure roller 303 and the support roller 302 are made of sponge material, and the pressure roller 303 and support roller 302 are tightly fitted together. During compression, the dye inside the sponge is forced into the spandex fiber cloth by external force, allowing the dye to quickly penetrate the spandex fiber cloth. This device... When in use, the spandex fiber cloth 2 is soaked in dye inside the water tank 1. Under the action of the external traction device, the spandex fiber cloth 2 is conveyed between the pressure roller 303 and the support roller 302. The pressure roller 303 and the support roller 302 will squeeze the spandex fiber cloth 2 between them. Through the sponge material outside the pressure roller 303 and the support roller 302, the dye inside the sponge can be squeezed into the interior of the spandex fiber cloth 2 by external force during the squeezing, so that the dye can quickly penetrate into the interior of the spandex fiber cloth 2, thereby improving the dyeing efficiency.

[0021] Example 2:

[0022] Please see Figure 1-4This utility model provides a technical solution: a device for dyeing spandex fibers. The tension adjustment mechanism 8 includes a first column 801, the bottom of which is welded to the bottom of a water tank 1. The inside of the first column 801 is slidably connected to a first slider 802. The first slider 802 is rotatably connected to the end of a tension roller 803, and the top of the first slider 802 is rotatably connected to the bottom end of a first threaded rod 804. The outer wall of the first threaded rod 804 is threadedly connected to the top end of the first column 801. When both ends of the spandex fiber cloth are fixed in the fabric feeding and receiving equipment, the downward movement of the tension roller increases the tension of the spandex fiber cloth, thereby increasing the internal voids of the spandex fiber cloth. The dye can penetrate the interior more easily; the nozzle 4 has a flat outlet and is located above the spandex fiber cloth 2. The dye is sprayed at high pressure onto the surface of the spandex fiber cloth through the nozzle, which helps to further promote the dye to penetrate into the interior of the spandex fiber cloth. By rotating the first threaded rod 804, the first threaded rod 804 can drive the first slider 802 to move downward, which in turn can drive the tension roller 803 to move downward. When the two ends of the spandex fiber cloth 2 are fixed in the fabric taking-up and putting-down equipment, the downward movement of the tension roller 803 will increase the tension of the spandex fiber cloth 2, which will increase the gap inside the spandex fiber cloth 2, making it easier for the dye to penetrate into the interior.
