Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric dyeing, in particular to a non-woven fabric dyeing device for a framework. Background Art

[0002] As the most core component for capturing solid-phase substances in an air purification system, the filter material plays a decisive role in the purification effect. Currently, the mainstream high-efficiency filter materials on the market include PP melt-blown non-woven fabric, PTFE membrane material, nanofiber material, etc. Since the high-efficiency filter material is soft and has poor strength, it is generally used in combination with a framework non-woven fabric.

[0003] During the production process of the framework non-woven fabric, a dyeing device is sometimes required for dyeing treatment. The patent with the patent number CN220846664U discloses a continuous dyeing device for non-woven fabric production. When in use, the fabric to be dyed is sequentially passed through the inside of the first conveying roller and the second conveying roller. Through the drive of the drive motor, the first conveying roller at the end is controlled to rotate, so that the rotatably arranged first conveying roller and the second conveying roller can convey the fabric, and the fabric can always be kept in a spread state inside the dyeing tank body.

[0004] When the above dyeing device dyes, the fabric continuously passes through the dyeing tank body, lacking extrusion of the fabric, which may make it difficult for the dyeing liquid to quickly and completely penetrate the fabric, resulting in uneven local dyeing. If, for example, the penetration effect is to be improved, the time for the fabric to pass through the dyeing tank body needs to be increased, that is, the contact time between the fabric and the dyeing liquid is increased, but this will lead to a long dyeing time and a decrease in production efficiency.

Specific embodiments

[0021] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0022] Please refer to Figures 1 to 5 , the embodiment of the present application provides a skeleton non-woven fabric dyeing device, including a frame 1 and a guide roller group installed on the frame 1. A dyeing tank 2 is fixed on the frame 1, and two extrusion coloring rollers 3 distributed up and down are rotatably installed in the dyeing tank 2. Two extrusion dewatering rollers 4 are rotatably installed on the frame 1 and above the dyeing tank 2;

[0023] The guide roller set includes a first guide roller 21, a second guide roller 22, a third guide roller 23, and a terminal guide roller 6. The first guide roller 21, the second guide roller 22, the third guide roller 23, and the terminal guide roller 6 are all rotatably connected to the frame. The skeletal non-woven fabric 5 sequentially passes through the gaps between the first guide roller 21, the second guide roller 22, the third guide roller 23, the terminal guide roller 6, the two extrusion coloring rollers 3, and the two extrusion dewatering rollers 4. The first guide roller 21, the second guide roller 22, the third guide roller 23, and the terminal guide roller 6 guide the skeletal non-woven fabric 5. The two extrusion coloring rollers 3 cooperate to extrude the skeletal non-woven fabric 5, and the pressure is used to make the dye quickly, fully, and evenly enter the interior of the skeletal non-woven fabric 5, thereby improving the dyeing uniformity and the dyeing efficiency. The two extrusion dewatering rollers 4 cooperate to extrude the skeletal non-woven fabric 5, and the excess dyeing liquid on the skeletal non-woven fabric 5 is extruded by the pressure, facilitating the subsequent drying treatment of the skeletal non-woven fabric 5.

[0024] The terminal guide roller 6 is located above the extrusion coloring rollers 3. Baffles 7 are provided on both sides of the gap between the terminal guide roller 6 and the dyeing pool 2, and the baffles 7 are fixedly connected to the dyeing pool 2. A circulation pump 8 and a pre-dyeing pipe 9 are fixed on the frame 1. The input end of the circulation pump 8 is connected to the bottom of the dyeing pool 2 through a circulation feed pipe 10, and the output end of the circulation pump 8 is connected to the pre-dyeing pipe 9 through a circulation supply pipe 11. The pre-dyeing pipe 9 is located between the two baffles 7, and a plurality of nozzles 12 with the jet direction facing the conveying path of the skeletal non-woven fabric 5 are provided on the pre-dyeing pipe 9. The circulation pump 8 pumps the dyeing liquid into the dyeing pool 2 through the circulation feed pipe 10 and continuously conveys the dyeing liquid to the pre-dyeing pipe 9 through the circulation supply pipe 11. When the skeletal non-woven fabric 5 passes between the terminal guide roller 6 and the extrusion coloring rollers 3, the pre-dyeing pipe 9 sprays the dyeing liquid onto the skeletal non-woven fabric 5 through the nozzles 12 to wet and pre-dye the skeletal non-woven fabric 5, improving the dyeing effect on the skeletal non-woven fabric 5. The baffles 7 can prevent the dyeing liquid sprayed by the nozzles 12 from splashing. After the dyeing liquid sprayed by the nozzles 12 contacts the skeletal non-woven fabric 5, the excess dyeing liquid on the skeletal non-woven fabric 5 drips downward and re-enters the dyeing pool 2, realizing the circulating flow of the dyeing liquid, avoiding the static precipitation and stratification of the dyeing liquid in the dyeing pool 2, improving the dyeing uniformity, and improving the dyeing effect on the skeletal non-woven fabric 5.

[0025] To facilitate driving the rotation of the two extrusion and coloring rollers 3 and the two extrusion and dehydration rollers 4 and maintaining the synchronous conveyance of the skeletal non-woven fabric 5, a drive motor 13 is installed on the frame 1. The drive motor 13 is a reduction motor. A third sprocket 14 is installed at the output end of the drive motor 13. One end of each of the two extrusion and dehydration rollers 4 is installed with a first gear 15, and the two first gears 15 are meshed and connected. A first sprocket 16 is installed at one end of one of the extrusion and dehydration rollers 4. One end of each of the two extrusion and coloring rollers 3 is installed with a second gear 17 and a second sprocket 18, and the two second gears 17 are meshed and connected. The third sprocket 14 is in transmission connection with the second sprocket 18 on the lower extrusion and coloring roller 3 through a first chain 19. The first sprocket 16 is in transmission connection with the second sprocket 18 on the upper extrusion and coloring roller 3 through a second chain 20.

[0026] The drive motor 13 drives the third sprocket 14 to rotate. The third sprocket 14 drives the second sprocket 18 on the lower extrusion and coloring roller 3 to rotate through the first chain 19, and then drives the lower extrusion and coloring roller 3 to rotate. The lower extrusion and coloring roller 3 drives the upper extrusion and coloring roller 3 to rotate through the second gear 17, thereby realizing the synchronous reverse rotation of the two extrusion and coloring rollers 3. The upper extrusion and coloring roller 3 drives the first sprocket 16 to rotate through the second sprocket 18 and the second chain 20. The extrusion and dehydration roller 4 connected to the first sprocket 16 rotates accordingly, and drives the other extrusion and dehydration roller 4 to rotate through the first gear 15, thereby realizing the synchronous reverse rotation of the two extrusion and dehydration rollers ”. The extrusion and dehydration rollers 4 and the extrusion and coloring rollers 3 rotate in the same direction at the same speed, which can maintain the stable traction of the skeletal non-woven fabric 5.

[0027] To prevent the skeletal non-woven fabric 5 from swinging too much when the nozzle 12 sprays water on the skeletal non-woven fabric 5, a first anti-deviation rod 24 and a second anti-deviation rod 25 are also provided. The first anti-deviation rod 24 and the second anti-deviation rod 25 are both fixedly connected to the frame 1. The first anti-deviation rod 24 is obliquely above the second anti-deviation rod 25. The first anti-deviation rod 24 is directly below the end guide roller 6. The vertical projection parts of the first anti-deviation rod 24 and the second anti-deviation rod 25 overlap. The skeletal non-woven fabric 5 passes through the end guide roller 6 and then passes through the first anti-deviation rod 24 and the second anti-deviation rod 25 in sequence. The first anti-deviation rod 24 and the second anti-deviation rod 25 are respectively in contact with the two side surfaces of the skeletal non-woven fabric 5 to limit the swing of the skeletal non-woven fabric 5 and ensure the stability of the conveyance of the skeletal non-woven fabric 5.

[0028] To facilitate the straight upward entry of the skeletal non-woven fabric 5 into the gap between the two squeezing and dewatering rollers 4, a guiding roller 26 is rotatably installed in the dyeing tank 2. The guiding roller 26 is located on one side of the squeezing and coloring roller 3. After the skeletal non-woven fabric 5 passes through the gap between the two squeezing and coloring rollers 3, it successively passes through the guiding roller 26 and the gap between the two squeezing and dewatering rollers 4. After passing through the guiding roller 26, the skeletal non-woven fabric 5 will vertically enter the gap between the two squeezing and dewatering rollers 4, which facilitates the squeezing of the skeletal non-woven fabric 5 by the squeezing and dewatering rollers 4 and the return of the squeezed dyeing liquid to the dyeing tank 2.

[0029] To facilitate the detection of the liquid level in the dyeing tank 2, an upper liquid level switch 27 and a lower liquid level switch 28 are installed on the dyeing tank 2. The upper liquid level switch 27 is located above the lower liquid level switch 28. The upper liquid level switch 27 detects the highest liquid level of the dyeing tank 2, and the lower liquid level switch 28 detects the lowest liquid level of the dyeing tank 2; the upper liquid level switch 27 and the lower liquid level switch 28 are electrically connected to the controller on the production line of the skeletal non-woven fabric 5 to realize the monitoring of the liquid level.
