[0001] This utility model relates to the field of printing and dyeing equipment technology, specifically to a high-efficiency and energy-saving cold dyeing machine. Background Technology

[0002] In recent years, with the continuous development of the textile industry, people have increasingly higher requirements for the color and comfort of clothing, resulting in a surge in the sales of knitted fabrics. Cold dyeing machines are an indispensable piece of equipment in the dyeing process of knitted fabrics. These machines can be used for cold-batch dyeing processes with reactive dyes, offering advantages such as convenient processing, good even dyeing, and washability.

[0003] During the fabric dyeing process, the dye inside the dyeing box is prone to sedimentation, resulting in uneven dyeing of the fabric. Furthermore, when the fabric is removed from the dyeing box, it carries a large amount of excess dye liquor. As the fabric moves, the dye liquor drips, causing pollution and further wasting the dye liquor, thus affecting the actual use effect. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a high-efficiency and energy-saving cold dyeing machine, including a dyeing box 1, a support frame 2 on the outside of the dyeing box 1, and a plurality of guide rollers 3 rotating at both ends on the inner wall of the support frame 2. The top of the dyeing box 1 is welded and fixed to a transmission roller 4. The dyeing box 1 is connected and fixed to a fixed frame 16. A take-up roller is set below the fixed frame 16. Fabric is placed on the outside of the guide rollers 3. The fabric enters the dyeing box 1 through the guide rollers 3 and the transmission rollers 4, is pulled by the dyeing roller 5, and then wound up on the outside of the take-up roller.

[0021] The dyeing box 1 is fitted with three dyeing rollers 5 at both ends, which rotate in a triangular arrangement to extend the immersion time of the fabric and ensure the best dyeing effect.

[0022] A motor is fixedly installed on the side of the dyeing box 1. The drive shaft 6 is connected and fixed to the output end of the motor. The outer side of the drive shaft 6 is welded and fixed to the stirring blade 7. The drive shaft 6 drives the stirring blade 7 to rotate, creating turbulence, thereby accelerating the uniformity of the dyeing box 1. The stirring blades 7 are symmetrically distributed on both sides of the inner wall of the dyeing box 1, reducing the generation of dead zones. The rotation of the stirring blades 7 can prevent the lint from the dyeing fabric from easily getting tangled on the stirring plate during mixing, ensuring the long-term effectiveness of the stirring blades 7.

[0023] The dyeing chamber 1 is bolted to the side of a circulating pump 8. The output end of the circulating pump 8 is connected to a water pipe 9. One end of the water pipe 9 is connected to the bottom of the dyeing chamber 1, and the other end is welded to a water conveying plate 10. The interior of the dyeing chamber 1 is welded to the water conveying plate 10. The water conveying plate 10 is located above the dyeing roller 5, and the water pipe 9 is located between the stirring blades 7. The dye liquor is pumped into the water conveying plate 10 through the water pipe 9 by the circulating pump 8. A nozzle is provided at the bottom of the water conveying plate 10, through which the dye liquor is sprayed out at high speed for dyeing, thereby improving dyeing efficiency.

[0024] The dyeing box 1 is fixedly connected to both ends of the mating roller 11. The upper part of the mating roller 11 is in contact with the outer side of the extrusion roller 12. Both ends of the extrusion roller 12 are welded and fixed to the connecting plate 13. The side of the connecting plate 13 is welded and fixed to the rotating shaft 14. One end of the rotating shaft 14 is rotatably connected to the inner wall of the dyeing box 1. A torsion spring 15 is sleeved on the outer side of the rotating shaft 14. The elastic force of the torsion spring 15 ensures that the connecting plate 13 drives the extrusion roller 12 to rotate, ensuring that the extrusion roller 12 is always in contact with the outer side of the mating roller 11.

[0025] Support frame 2 is welded and fixed to fixed frame 16. Fixed frame 16 is hinged to adjusting frame 17. Adjusting frame 2 19 is installed below adjusting frame 17.

[0026] The inner wall of the fixed frame 16 is hinged to one end of the adjusting frame 17 and the adjusting frame 19, respectively. Telescopic rod 18 and telescopic rod 20 are fixedly installed on the side of the fixed frame 16. The output end of telescopic rod 18 is hinged to the adjusting frame 17, and the output end of telescopic rod 20 is hinged to the adjusting frame 19. The inner wall of the adjusting frame 17 is rotatably connected to both ends of the adjusting roller 1, and the inner wall of the adjusting frame 19 is rotatably connected to both ends of the adjusting roller 2.

[0027] Working Principle: During operation, one end of the fabric is passed through guide roller 3, transmission roller 4, dyeing roller 5, adjusting frame 2 19, and adjusting frame 17 until it is collected on the take-up roller. The motor drives the drive shaft 6 to rotate the stirring blade 7, which mixes the dye liquor inside the dyeing box 1, preventing dye sedimentation and uneven dyeing. A circulating pump 8 directs the dye liquor from the dyeing box 1 through water pipe 9 into the water conveying plate 10. The water conveying plate 10 sprays the dye liquor at high speed onto the fabric surface of the dyeing roller 5 through nozzles at its bottom, promoting dyeing effect and improving dyeing efficiency. The circulating flow of the dye liquor creates convection, ensuring uniformity of the dye liquor inside the dyeing box 1. The torsion spring 15 causes the connecting plate 13 to move the extrusion roller 12 towards the mating roller 11. The mating roller 11 and the extrusion roller 12 squeeze out excess dye liquor from the fabric, preventing dripping and waste, and improving the energy efficiency of the cold dyeing machine.

[0028] In addition, the tension of the surface fabric is adjusted by using the telescopic rod 18 to swing the adjusting frame 17 and the telescopic rod 20 to swing the adjusting frame 19. The tension of the fabric is adjusted by changing the position of the adjusting roller 1 and the adjusting roller 2, so as to ensure that the tension of the fabric is constant.
