[0030] In this embodiment, the flow of fabric is guided by the guide roller 8 to ensure that the fabric moves smoothly between the dyeing tank 2, the filter press tank 3 and the dust removal tank 4. The stirring mechanism 5 is connected to the dyeing tank 2, and the dyeing liquid is stirred evenly during the dyeing process to avoid dye precipitation or uneven penetration. The filter press mechanism 6 is used to press out the excess dyeing liquid carried on the surface of the dyed fabric, thereby reducing the waste of dye and improving the utilization rate of dye. It also helps the subsequent drying process and reduces energy consumption. The dust and impurities on the surface of the fabric are sucked away by the dust suction mechanism 7 to avoid stains or impurities affecting the dyeing effect. The cooperation of the stirring mechanism 5 and the dust suction mechanism 7 ensures that the dyeing liquid penetrates evenly and there are no impurities on the surface of the fabric, thereby achieving a better dyeing effect. The filter press mechanism 6 effectively removes excess dyeing liquid, reduces dye waste, and reduces energy consumption during drying. Resource consumption is reduced through multiple mechanisms such as filter pressing and dust suction, which meets modern environmental protection standards and effectively reduces waste emissions in the production process.

[0031] like Figure 1 and Figure 3 As shown, the stirring mechanism 5 includes a driving component 51, and the driving component 51 is connected to the driving shaft 52. The lower part of the driving shaft 52 is connected to the bulk material component 53, and the driving shaft 52 is connected with a stirring cross bar 55 and an auger 54; through the operation of the driving component 51, the auger 54 and multiple stirring cross bars 55 can be driven to rotate, and the dyeing liquid in the dyeing tank 2 can be lifted and stirred by the auger 54, so that the dyeing liquid can be turned up and down, and the dyeing liquid can be stirred horizontally in conjunction with multiple stirring cross bars 55, thereby enhancing the stirring effect.

[0032] The driving shaft 52 is a hollow shaft.

The upper part of the pressing plate 61 is connected to the first electric lifting rod 63, and the lower part of the filter plate 62 is connected to the support seat 64. A filter screen 65 is arranged inside the filter plate 62. The pressing plate 61 and the filter plate 62 have the same length. The first electric lifting rod 63 works to drive the pressing plate 61 to descend, squeeze the fabric between the pressing plate 61 and the filter plate 62, and press out the excess dyeing liquid carried on the surface of the fabric, which helps to reduce the waste of dyes and improve the utilization rate of dyes. It also helps the subsequent drying process and reduces energy consumption.

[0034] Among them, the cross-sections of the pressure plate 61 and the filter plate 62 are both in an eight-shape; the eight-shaped cross-section can form a more uniform pressure distribution between the pressure plate 61 and the filter plate 62, ensuring a more thorough separation of liquid and solid during the filtration process and reducing the risk of liquid leaking through the filter screen. The eight-shaped design enables the two plates to distribute force more evenly when under pressure, thereby improving the overall strength and stability of the system, enhancing the durability of the structure, and adapting to high-pressure environments.

[0036] Among them, the upper vacuum pipe 73 and the lower vacuum pipe 74 are respectively located above and below the fabric, responsible for vacuuming the fabric in all directions. The two pipes provide a flexible vacuuming area, which can clean different surfaces of the fabric respectively. Multiple vacuum heads 75 are in contact with the fabric, responsible for sucking dust, fibers and other impurities on the surface of the fabric into the system. The vacuum head 75 can be equipped with a cushion, bristle or suction nozzle suitable for various fabrics to ensure that the surface of the fabric can be cleaned gently and effectively without damaging the fabric. Through the combined action of the upper and lower vacuum pipes and the vacuum head, the dust and impurities on the surface of the fabric can be fully cleaned, ensuring that the fabric reaches the best cleaning state before dyeing, and avoiding impurities affecting the dyeing quality.

The material shaft 532 will drive the first bevel gear 533 to rotate, the first bevel gear 533 will drive the second bevel gear 534 and the rotating shaft 535 to rotate, and the rotating shaft 535 will drive the stirring vertical rod 536 and the bulk rod 537 to rotate. The vertical stirring by the stirring vertical rod 536 and the horizontal stirring by the stirring cross bar 55 can enhance the stirring effect. The bulk rod 537 can rotate and the horizontal stirring by the stirring cross bar 55 can further enhance the stirring effect. At the same time, the bulk rod 537 will hit the fabric, and can also ensure that the fabric is fully in contact with the dye during the dyeing process, avoid uneven dyeing, and improve the stability and consistency of the dyeing effect.

[0039] The bulk material shaft 532 is located inside the driving shaft 52 , and the bulk material shaft 532 passes through the driving shaft 52 and is connected to the driving motor 538 .

[0040] like Figure 1 and Figure 2 As shown, an upper squeezing roller 9 and a lower squeezing roller 10 are arranged inside the filter press tank 3, a second electric lifting rod 11 is connected above the upper squeezing roller 9, and a guide plate 12 is arranged inside the filter press tank 3; the dyed fabric can be pre-extruded by the upper squeezing roller 9 and the lower squeezing roller 10, and the dyed fabric can be pre-extruded while the pressing plate 61 and the filter plate 62 are working, thereby improving the squeezing efficiency.

[0041] Among them, the filter press mechanism 6 is provided with upper squeezing rollers 9 and lower squeezing rollers 10 in front and behind. Pre-squeezing is performed by the upper squeezing rollers 9 and lower squeezing rollers 10 in front, and the pressurized fabric can be flattened by the upper squeezing rollers 9 and lower squeezing rollers 10 in the rear.

[0042] like Figure 1 and Figure 2 As shown, the bottom of the filter press tank 3 is connected to one end of a liquid pump 14 through a liquid extraction pipe 13, and the other end of the liquid extraction pump 14 is connected to the dyeing tank 2 through a liquid discharge pipe 15; when the liquid extraction pump 14 works, the dyeing liquid collected at the bottom of the filter press tank 3 can be extracted through the liquid extraction pipe 13, and discharged into the dyeing tank 2 again through the liquid discharge pipe 15 for use, and the dyeing liquid at the bottom of the filter press tank 3 can be directly discharged through the set discharge pipe.

[0043] A multifunctional and environmentally friendly dyeing method is used for the four-piece sea island cotton fabric with high color fastness. S1. The fabric to be dyed is sent into the box 1 through the guide roller 8, and the dust is first removed from the fabric through the dust suction mechanism 7 in the dust removal tank 4; S2. The dust-removed fabric enters the dyeing tank 2 for dyeing, and the stirring mechanism 5 is started to stir the dyeing liquid and beat the fabric at the same time; S3. After dyeing, the fabric enters the filter press tank 3, and the filter press mechanism 6 works to squeeze out the dyeing liquid carried on the fabric, which is convenient for subsequent drying treatment.

The stirring mechanism 5 and the beating mechanism not only help to evenly stir the dye, but also ensure that the fabric is fully in contact with the dye during the dyeing process, avoid uneven dyeing, and improve the stability and consistency of the dyeing effect. The filter press mechanism 6 effectively squeezes out the excess dyeing liquid on the fabric, reducing the residual and waste of the dye. This not only reduces production costs, but also reduces environmental pollution. Through efficient dyeing and filtering processes, the use of dyeing liquid and energy consumption can be reduced. Since the excess dyeing liquid can be quickly squeezed out and processed, the fabric does not need too much heat energy consumption during the drying process, and the overall process is more energy-efficient. The method not only improves the dyeing quality and optimizes the dyeing process, but also effectively saves resources, improves production efficiency, and meets modern environmental protection requirements.

[0045] Working principle: the flow of fabric is guided by the guide roller 8 to ensure that the fabric moves smoothly between the dyeing tank 2, the filter press tank 3 and the dust removal tank 4. The stirring mechanism 5 is connected to the dyeing tank 2 to stir the dyeing liquid evenly during the dyeing process to avoid dye precipitation or uneven penetration. The filter press mechanism 6 presses out the excess dyeing liquid carried on the surface of the dyed fabric, which reduces the waste of dye and improves the utilization rate of dye. It also helps the subsequent drying process and reduces energy consumption. The dust and impurities on the surface of the fabric are sucked away by the dust suction mechanism 7 to avoid stains or impurities affecting the dyeing effect. The cooperation of the stirring mechanism 5 and the dust suction mechanism 7 ensures that the dyeing liquid penetrates evenly and there are no impurities on the surface of the fabric, thereby achieving a better dyeing effect. The filter press mechanism 6 effectively removes excess dyeing liquid, reduces dye waste, and reduces energy consumption during drying. Resource consumption is reduced through multiple mechanisms such as filter pressing and dust suction, which meets modern environmental protection standards and effectively reduces waste emissions in the production process.
