[0003] Traditional dyeing machines are commonly used in the dyeing of linen and its blended fabrics. These machines suffer from significant resource waste and dyeing quality issues during operation. Due to the specific characteristics of linen fibers, traditional dyeing machines often require large amounts of water to improve fabric softness and even dye penetration, resulting in significant water consumption, increased dyeing costs, and increased burdens on subsequent wastewater treatment. Furthermore, traditional dyeing machines often rely on mechanical agitation or simple circulation to drive the dye liquor, making it difficult to tailor the dyeing process to the specific characteristics of linen and its blended fabrics. This can easily lead to uneven dyeing, noticeable color differences, and lower the yield rate of finished products. Summary of the Invention

The ice water immersion chamber can perform low-temperature pretreatment on dyed fabrics, inhibit the fibers from adsorbing dyes prematurely, reduce dye waste, and help reduce overall water consumption; the shaking chamber improves the fabric state through shaking operations, loosens the fiber structure, and allows subsequent dyes to penetrate the fiber more evenly, thereby effectively improving dyeing uniformity; the high-temperature airflow injection chamber preheats the dyed fabrics through high-temperature airflow, thereby increasing the fiber's affinity for dyes, and can reduce the use of traditional liquid media under gaseous conditions, further saving water; the dyeing chamber sets reasonable temperature control conditions for linen and its blended fabrics to improve the dye fixation efficiency and ensure dyeing quality; the airflow drying chamber utilizes high-efficiency airflow drying technology to quickly remove moisture while reducing energy consumption, avoiding the waste of large amounts of water resources and energy in traditional drying; the washing chamber washes the dyed fabrics in steps, further reducing water consumption during the washing process, improving dyeing uniformity and quality, and fully adapting to the characteristics of linen and its blended fabrics that are coarse and difficult to color evenly.

[0016] 2.

The spray pipes are connected to a high-temperature steam generator to continuously provide high-temperature steam to the atomizing nozzles. Through the rapid penetration of the high-temperature airflow, the dyed fabric can complete the preheating treatment without relying on a large amount of liquid immersion, which not only improves the activation degree of the dyed fabric fibers and enhances the subsequent dyeing effect, but also significantly reduces the consumption of water resources in the traditional pretreatment process. At the same time, the fine mist steam injection from the atomizing nozzle avoids the local wet weight unevenness of the fabric caused by direct contact of water droplets, helps to maintain the stability of the overall fabric state, and lays a good foundation for achieving subsequent efficient and uniform dyeing.

DETAILED DESCRIPTION

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0020] Example: Refer to the following Figures 1-6As shown, and further described with reference to specific embodiments, this embodiment provides an energy-saving dyeing machine, comprising a dyeing machine body 1. The dyeing machine body 1 is provided with a plurality of chambers arranged sequentially from the inlet side to the outlet side (i.e., from left to right) of the dyed fabric. These chambers are arranged sequentially to allow the dyed fabric to pass through each processing stage according to a predetermined process, achieving efficient and continuous dyeing operations. The chambers include an ice water immersion chamber 11, a shaking chamber 12, a high-temperature airflow injection chamber 13, a dyeing chamber 14, an airflow drying chamber 15, and a cleaning chamber 16. Each chamber is independent yet interconnected, ensuring the independence and specificity of each processing step while facilitating continuous transport of the dyed fabric during processing, thereby avoiding energy consumption and losses associated with multiple handling.

[0021] Among them, the ice water immersion chamber 11 is used to perform low-temperature pretreatment on the dyed fabric, by lowering the temperature of the dyed fabric to improve the fiber structure state and improve the subsequent dyeing uniformity; the shaking chamber 12 is used to shake the dyed fabric, by mechanically shaking off the fibers on the surface of the fabric, and further improving the looseness and flatness of the fabric; the high-temperature airflow injection chamber 13 is used to preheat the dyed fabric through high-temperature airflow to stimulate fiber activity and increase the dyeing reaction rate; the dyeing chamber 14 is used to dye the dyed fabric to ensure that the dye fully penetrates into the fiber; the airflow drying chamber 15 is used to dry the dyed fabric with airflow to quickly evaporate moisture and maintain the softness of the fabric; the cleaning chamber 16 is used to clean the dyed fabric to remove excess dye and chemical additives to ensure the quality of the finished product.

[0022] Reference Figure 1 and Figure 3 As shown, the ice water immersion chamber 11, shaking chamber 12, high-temperature airflow injection chamber 13, dyeing chamber 14, airflow drying chamber 15, and cleaning chamber 16 are all adjacently arranged. Each chamber has an inlet and outlet 17 near the top, forming a connecting passage between each inlet and outlet 17 to facilitate smooth conveyance of the dyed fabric between the chambers. Furthermore, a first guide roller 171 is rotatably mounted at each inlet and outlet 17. The first guide roller 171 is positioned above the chamber and, through its rotational guidance, allows the dyed fabric to smoothly transition between the different chambers, avoiding problems such as folding, tangling, or jamming, thereby improving conveyance smoothness.

[0023] At the same time, the ice water immersion chamber 11, shaking chamber 12, high-temperature airflow injection chamber 13, dyeing chamber 14, airflow drying chamber 15, and cleaning chamber 16 are all rotatably provided with second guide rollers 2 near the bottom wall. The second guide rollers 2 play an auxiliary supporting and guiding role relative to the first guide rollers 171. In particular, when the dyed fabric enters the bottom area of each chamber, it can effectively maintain the fabric tension and prevent the dyed fabric from sagging or wrinkling due to gravity, further improving the overall conveying quality and subsequent processing effects. The first guide rollers 171 and the second guide rollers 2 work in conjunction, allowing the dyed fabric to be continuously conveyed in each chamber along a predetermined path and in a stable state.

[0024] Reference Figure 3 and Figure 5 As shown, a pair of shaking rollers 121 are installed inside the shaking chamber 12. The pair of shaking rollers 121 are arranged parallel to each other and are respectively connected and fixed to the opposite side walls of the shaking chamber 12 through a vibration motor 122. The vibration motor 122 is preferably a waterproof motor to adapt to the working requirements of the high humidity or liquid environment in the shaking chamber 12, thereby extending the service life of the motor and improving the reliability of the equipment operation. In terms of the specific installation method, the vibration motor 122 can be directly installed on the inner side wall of the shaking chamber 12, or the vibration motor 122 can be installed outside the shaking chamber 12 and connected to the shaking roller 121 through a linkage mechanism to further improve the convenience of maintenance and inspection. The shaking roller 121 is configured to be able to directly abut the surface of the passing dyed fabric. The high-speed vibration generated by the vibration motor 122 causes the shaking roller 121 to apply continuous slight impact to the dyed fabric, thereby effectively relaxing and stretching the fabric fiber structure, eliminating wrinkles and local deformation that may be formed during the weaving process, optimizing the state of the dyed fabric, and creating a good foundation for subsequent high-temperature airflow preheating and dyeing treatment.

[0025] Of course, in other embodiments, multiple pairs of shaking rollers 121 may be added according to actual process requirements to further improve the uniformity and thoroughness of the shaking treatment of the dyed fabric through multi-point and multi-frequency coordinated vibration, so as to better adapt to the processing requirements of different types of dyed fabrics.

[0026] Reference Figure 3 and Figure 5As shown, the high-temperature airflow injection chamber 13 includes a plurality of spray pipes 131, which are arranged in pairs along the transverse direction of the high-temperature airflow injection chamber 13 and are reasonably spaced apart from each other to ensure that the airflow injection effect covers the entire width of the dyed fabric. In the present embodiment, a plurality of atomizing nozzles 1311 are evenly spaced and connected and installed on each spray pipe 131, and the spray direction of the atomizing nozzle 1311 is set toward the dyed fabric conveying path to ensure that the high-temperature steam can act evenly on the surface of the dyed fabric. Each spray pipe 131 is connected to a high-temperature steam generator 132 through a pipeline. The high-temperature steam generator 132 is configured to continuously and stably generate high-temperature and high-pressure steam for use by the atomizing nozzle 1311, and the steam generator can be provided with a temperature regulating mechanism to facilitate adjusting the steam temperature and pressure according to different fabric materials and processing requirements. The high-temperature steam generator 132 is prior art and is not described in detail here.

[0027] In practice, high-temperature steam is sprayed onto the surface of the dyed fabric in the form of a fine mist through atomizing nozzle 1311, quickly and evenly preheating the fabric in a short period of time. This helps to open up the fabric fiber structure, improve the permeability and adhesion of dye molecules in the subsequent dyeing process, and enhance overall dyeing uniformity and quality. Furthermore, the high-temperature steam can effectively kill bacteria and microorganisms on the surface of the dyed fabric, providing a certain disinfecting effect and further optimizing the fabric treatment effect.

[0028] Reference Figure 3 and Figure 4 As shown, multiple pairs of second guide rollers 2 are provided within the dyeing chamber 14, with each pair of second guide rollers 2 positioned opposite each other and arranged sequentially along the conveying direction of the dyed fabric. These multiple pairs of second guide rollers 2 not only effectively guide and support the conveyance of the dyed fabric within the dyeing chamber 14, but also allow for flexible adjustment of their arrangement. For example, they can be arranged in a single row, double row, or multiple rows in a serpentine pattern depending on actual spatial conditions, thereby increasing the fabric's residence time and movement trajectory within the dyeing chamber 14, thereby ensuring sufficient contact between the fabric and the dyeing liquid and improving dyeing uniformity. The dyeing chamber is equipped with a silo (not shown) to supply dye to it. Multiple silos can be provided depending on dye demand, and the dye is pumped into the dyeing chamber or automatically fed by gravity.

[0029] Each pair of second guide rollers 2 is sheathed with a deformable bladder 3. Made of elastic material, the bladder 3 expands and contracts by filling or draining a medium (such as gas or liquid). This periodic expansion and contraction provides a gentle, continuous kneading effect on the dyed fabric, enhancing the dye's penetration and adhesion to the fibers and further improving the dyeing process. This design is particularly suitable for high-end fabric dyeing processes requiring precise dyeing uniformity.

[0030] Reference Figure 4As shown, the deformable sacs 3 installed on the outside of the second guide roller 2 in the dyeing chamber 14 are all eccentrically set, that is, the expansion center axis of the deformable sacs 3 is slightly offset from the rotation center axis of the second guide roller 2. Through the eccentric design, non-uniform rubbing force can be generated on the dyed fabric during the expansion of the deformable sacs 3, thereby generating different degrees of squeezing and release in local areas, which helps to better break up the fiber bundles and improve dyeing uniformity. A plurality of elastic plates 31 are further provided inside the deformable sacs 3. The elastic plates 31 are made of a preferred rubber material and divide the internal space of the deformable sacs 3 into a plurality of independent compartments 311. Each compartment 311 can expand individually or collaboratively, thereby more finely controlling the deformation shape and rubbing effect of the sac. The second guide roller 2 itself adopts a hollow structure and is provided with a plurality of perforations 312 on the surface. These perforations 312 are connected to the plurality of compartments 311 inside the deformable sacs 3 in a one-to-one correspondence. By controlling the supply of the medium inside the second guide roller 2, each compartment 311 can be independently inflated and deflated or inflated simultaneously, further refining the dynamic changes of the deformable bag 3 and improving the controllability and precision of the dyeing fabric processing.

[0031] Reference Figure 3 As shown, the inner cavity of the dyeing chamber 14 is a U-shaped structure as a whole, and a pair of partitions 141 arranged in an inverted eight shape are installed at both ends of the U-shaped structure. The partitions 141 cooperate with the U-shaped cavity to form a certain restriction on the flow of the dyeing liquid during the dyeing process. An arc-shaped plate 142 is installed directly above the pair of partitions 141, and the arched surface of the arc-shaped plate 142 is arranged toward the top of the dyeing chamber 14. When the deformable bag 3 expands and causes the liquid level of the dyeing liquid to rise, the partition 141 and the arc-shaped plate 142 form a local narrow channel, which instantly hinders the flow of the dyeing liquid, causing the local dyeing liquid pressure to rise rapidly in a short time, thereby accelerating the penetration of dye molecules into the interior of the dyed fabric and improving dyeing efficiency and uniformity.

[0032] In addition, multiple third guide rollers 143 are installed near the partition 141 and the curved plate 142. The third guide rollers 143 are reasonably distributed and are used to guide the movement path of the dyed fabric to prevent the dyed fabric from being offset and misplaced due to liquid impact or bag expansion, thereby ensuring the continuity and stability of the dyeing process.

[0033] As an optional embodiment, a hot air blower 151 is installed at the bottom wall of the airflow drying chamber 15, and the air outlet 152 of the hot air blower 151 is arranged toward the top wall of the drying chamber to form a hot air flow field from bottom to top. The high-speed hot air flow generated by the hot air blower 151 can quickly penetrate the dyed fabric structure, effectively remove the residual moisture in the fabric, and achieve rapid drying. A plurality of exhaust ports are provided at the top of the drying chamber near the air outlet 152 to discharge the hot and humid air flow in time, to prevent water vapor from being retained and affecting the drying efficiency and fabric quality. Through the reasonable coordination of the hot air blower 151 and the exhaust port, a good airflow circulation system can be formed, which can improve the drying uniformity and overall energy efficiency and reduce energy consumption.

[0034] Reference Figure 3 As shown, the interior of the cleaning chamber 16 is divided into a plurality of water baffles 161, and each water baffle 161 is arranged in a stepped manner along the length direction of the cleaning chamber 16. The lowest water baffle 161 is provided at one end close to the airflow drying chamber 15, and adjacent water baffles 161 are separated by an isolation plate 160. A sealing strip is installed at the connection between the isolation plate 160 and the cleaning chamber 16 to ensure a good sealing effect between each water baffle 161 and avoid mutual contamination between different water qualities. The isolation plate 160 is driven horizontally or vertically by the cylinder 162, and can open the corresponding water baffle 161 as needed, so that the water in the water baffle 161 with a higher water level automatically flows to the water baffle 161 with a lower water level. In other embodiments, the cylinder 162 can also be replaced by an electric cylinder or other types of drive structures to adapt to different process requirements.

[0035] The lowest water tank 161 is connected to the dyeing chamber 14 through the first connecting pipe 4. A water pump 42 is installed on the first connecting pipe 4 to extract the water in the lowest water tank 161 and return it to the dyeing chamber 14 for recycling. An oblique filter plate 145 is provided at the bottom of the dyeing chamber 14. The filter plate adopts a multi-layer filtering structure design, which divides the bottom area into a filter chamber 146. The filter chamber 146 is connected to the highest water tank 161 through the second connecting pipe 41, and a water pump 42 is configured to extract cleaner water to flow into the highest water tank 161, thereby forming a recycling mechanism for cleaning water. Through the above design, the water resources in the cleaning process can be effectively recycled and utilized, while ensuring the cleanliness and stability of the dyeing process.

[0036] It should be noted that since the lowest water trap 161 is closer to the dyeing chamber 14, the water there is most susceptible to dyeing and thickening. Therefore, the liquid in the lowest water trap 161 can be pumped into the dyeing chamber 14 via the water pump 42 for reuse. The liquid in the highest water trap 161 is generally least stained by the dye. The relatively clean liquid in the filter chamber 146, filtered by the oblique filter plates 145 of the dyeing chamber 14, is then pumped into the highest water trap 161 via the water pump 42, thereby cleaning the dyed fabric. The cylinder 162 drives the isolation plates, allowing the water in the higher water trap 161 to automatically flow into the lower water traps 161 step by step, achieving the goal of cleaning the dyed fabric with relatively clean water.

[0037] Reference Figure 4 As shown, a tension roller 5 is rotatably mounted between each pair of adjacent second guide rollers 2 within the dyeing chamber 14. These rollers are used to apply appropriate tension to the fabric during conveyance. The ends of the tension rollers 5 slide within vertical chute 144 defined in the sidewalls of the dyeing chamber 14. These rollers automatically adapt to changes in tension caused by the expansion or contraction of the deformable bladder 3 during fabric conveyance, buffering and absorbing tension. This prevents fabric damage or poor conveyance due to excessive instantaneous tension, ensuring continuous and stable fabric processing.

[0038] As an optional embodiment, refer to Figure 1 and Figure 2 As shown, the ends of each pair of second guide rollers 2 in the dyeing chamber 14 are connected by a hose 6. The hose 6 is connected to the second guide roller 2 via a rotary joint 61, ensuring a normal supply of internal medium while the roller rotates. The hoses 6 adopt a cross-connected layout to form alternating inflation and deflation paths. Each hose 6 ultimately converges into a pump body 63, which can be an air source pump or a water source pump and is connected to the hose 6 system. The cross-connected hose 6 layout design can achieve unbalanced squeezing and kneading actions when the dyed fabric passes through the dyeing chamber 14, further improving the dyeing effect and allowing the dye to more fully penetrate the interior of the fabric fibers, ultimately achieving the goal of high-quality dyeing.

[0039] In addition, the present invention is achieved through the following technical solutions: A dyeing process, applicable to the energy-saving dyeing machine in the above scheme, comprises the following steps: S1: The dyed fabric is fed into the ice water immersion chamber 11, adjust the water temperature in the ice water immersion chamber 11 to 0 ° C-10 ° C, soak the dyed fabric to reduce the initial adsorption of the dye on the dyed fabric, while adjusting the acid-base balance to ensure the acid-base balance of the ice water immersion chamber 11; S2: The dyed fabric is fed into the shaking chamber 12, and the dyed fabric is properly shaken by the shaking roller 121 to loosen the fiber structure of the dyed fabric and ensure uniform dye penetration; S3: The dyed fabric is fed into the high-temperature air jet chamber 13, adjust the temperature of the high-temperature air jet chamber 13 to 90 ° C-120 ° C, the dyed fabric is preheated by the high-temperature air flow to promote better adsorption of the dye; S4: The dyed fabric is fed into the dyeing chamber 14, and the dyeing process is completed under appropriate temperature and humidity conditions. The temperature of the dyeing chamber 14 is controlled between 50 ° C-70 ° C to ensure that the dye is evenly attached to the surface of the dyed fabric; S5: sending the dyed fabric into the airflow drying chamber 15, adjusting the temperature of the airflow drying chamber 15 to 50°C-70°C, and drying the dyed fabric by airflow to remove excess moisture and accelerate the drying process; S6: The dyed fabric is sent to the cleaning chamber 16, where the fabric is cleaned to remove residual dye and other impurities to ensure that the dyeing quality meets the requirements; S7: Finally, the fabric is dried again.

[0040] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
