[0002] Non-aqueous medium salt-free and low-water dyeing technology is an innovative textile dyeing process. It achieves highly efficient and environmentally friendly dyeing results by replacing most of the water used in traditional dyeing processes with non-aqueous media and reducing or eliminating the use of salt compounds. This technology not only significantly saves water but also avoids environmental pollution caused by salt compounds, while ensuring high dye utilization and excellent dyeing results. This technology has broad application prospects in the textile industry and helps promote its sustainable development.

[0003] To rapidly and continuously dye textiles and improve dyeing efficiency, a continuous waterless dyeing equipment is needed.

[0004] In current continuous waterless dyeing equipment, after the non-aqueous, salt-free, low-water dye from the dye pan is applied to the textile material by the dyeing roller, the textile material needs to be removed and subjected to high-temperature steam fumigation to fix the color and increase color fastness. However, this process of removing the textile material and then subjecting it to high-temperature steam fumigation is cumbersome. Furthermore, the textile material cannot be fixed immediately after pad-dyeing, which can lead to color fading and uneven product color. Therefore, a continuous waterless dyeing equipment for textile printing and dyeing processes is proposed to solve the above problems. Utility Model Content

The bottom end of the dyeing roller 2 contacts the top end of the dyeing roller 3, so that the dye on the dyeing roller 3 is applied to the inside of the dyeing roller 2. A dye tray 4 is fixedly connected inside the fixed base 1, and salt-free and low-water dye is placed inside the dye tray 4. The bottom end of the dyeing roller 3 is located inside the dye tray 4. When the dyeing roller 3 rotates, the dye inside the dye tray 4 can adhere to the dyeing roller 3. A rotating sleeve 5 is rotatably connected inside the fixed base 1, two sets of rotating sleeves 5 symmetrically arranged on the front and rear sides of the fixed base 1. A steam roller 6 is fixedly connected to the inner side of the rotating sleeve 5. Several sets of through holes are evenly opened on the outer circumference of the steam roller 6 to allow high-temperature steam to pass through the steam roller 6. A fixed component is rotatably connected inside the rotating sleeve 5.

[0033] Reference Figures 2-4 The fixing assembly includes a fixing cylinder 7, which is rotatably connected to the inside of a rotating sleeve 5. A fixing bracket 8 is fixedly connected to the outside of the fixing cylinder 7 for fixing. The fixing bracket 8 is fixedly connected to the outside of the fixing base 1 to fix the fixing cylinder 7. A steam sleeve 9 is fixedly connected to the inside of the fixing assembly. The inside of the fixing cylinder 7 is fixedly connected to the outside of the steam sleeve 9. An exhaust port 10 is opened on the inside of the steam sleeve 9. The exhaust ports 10 on the left and right sides of the steam sleeve 9 are opposite to each other and face the inner textile material. A steam engine 11 is installed inside the steam sleeve 9. There is a gap between the outer periphery of the steam engine 11 and the steam sleeve 9. The steam outlet of the steam engine 11 is located at the top. When the steam engine 11 is turned on, it can spray high-temperature steam from the top.

[0034] Reference Figure 1 and Figure 5 A threaded post 12 is rotatably connected to the outer side of the dye tray 4. A rotating handle is provided on the outer side of the threaded post 12 for easy rotation. A connecting plate 13 is threadedly connected to the outer circumference of the threaded post 12. Rotation of the threaded post 12 can drive the connecting plate 13 to move along the outer wall of the threaded post 12. A sliding post 14 is fixedly connected to the inner side of the connecting plate 13. Two sets of sliding posts 14 are provided, symmetrically arranged on the right side of the connecting plate 13. The outer circumference of the sliding posts 14 is slidably connected to the inside of the dye tray 4. The two sets of sliding posts 14 prevent the connecting plate 13 from rotating. An abutment block 15 is fixedly connected to the inner side of the sliding post 14. A scraper 16 is in contact with the inner side of the abutment block 15. The abutment block 15 will push the scraper 16 to move left and right. A rotating shaft 17 is rotatably connected to the top of the scraper 16. The scraper 16 will rotate around the rotating shaft 17. Both ends of the rotating shaft 17 are rotatably connected to the inner side of the dye tray 4.

[0035] Working principle: When it is desired to quickly fix the color of the dyed fabric, the dyeing roller 3 rotates, dips the dye from the dye tray 4 and applies it to the surface of the dyeing roller 2. The rotating dyeing roller 2 squeezes and transfers the fabric from the middle, applying the dye to the fabric surface. The dyeing roller 2 is then transferred to the steam roller 6 at the bottom. At the same time, the steam engine 11 is turned on, emitting high-temperature steam. The high-temperature steam fills the interior of the steam sleeve 9 and is discharged from the exhaust port 10. Finally, the high-temperature steam is transferred to the fabric through the steam roller 6, thus enabling the fabric to be fixed at high temperature in time after dyeing, ensuring the color fastness of the dye and preventing color fading. After dyeing is completed, rotate the threaded column 12. The threaded column 12 drives the connecting plate 13 to move inward. The connecting plate 13 drives the sliding column 14 to move inward. The sliding column 14 drives the abutting block 15 to move inward. The abutting block 15 pushes the scraper 16 inward. The scraper 16 abuts against the dyeing roller 2 inward. At this time, the dyeing roller 2 rotates, and the scraper 16 scrapes off the dye on the outer periphery of the dyeing roller 2, thereby recovering the dye and increasing the utilization rate of the dye.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
