[0021] Reference Figure 1-Figure 7 A textile cloth dyeing device comprises a mounting seat 1, a dyeing pool 3 is fixedly connected to the upper end of the mounting seat 1, a plurality of unpowered rollers 7 are rotatably connected to the inner surface of the dyeing pool 3 through a rotating shaft, an inlet and outlet 11 are provided at both side ends of the dyeing pool 3, a fixing frame 17 and two mounting frames 8 are fixedly connected to the inner surface of the dyeing pool 3, a dyeing auxiliary mechanism for extracting and spraying dyes and assisting cloth dyeing is arranged in the fixing frame 17, a plurality of powered rollers 9 are rotatably connected to the inner surfaces of the two mounting frames 8 through bearings, and a filtering mechanism 14 for filtering the dyes extracted by the dyeing auxiliary mechanism is arranged in the dyeing pool 3.

[0022] The working principle of the device is as follows: the cloth enters and leaves the dyeing tank 3 through the inlet and outlet 11 opened at both sides of the dyeing tank 3. During the dyeing process, the cloth first passes through the unpowered rollers 7, which are connected to the inner surface of the dyeing tank 3 through the rotating shaft. They are mainly used to support and guide the path of the cloth so that the cloth can smoothly enter and leave the dyeing area. The cloth will then contact the power rollers 9 supported by the mounting frame 8. These power rollers 9 are connected to the mounting frame 8 through bearings and can actively rotate to push the cloth forward. The outer surface of each power roller 9 is sleeved with a limit seat, which is fixedly connected to the inner walls of the mounting frame 8 on both sides to ensure that the power roller 9 can run stably while keeping the position of the cloth accurate to avoid deviation. During the dyeing process, in order to ensure the uniform distribution and continuous supply of the dye solution, the device is equipped with a filter device 14, a water pump 15 and a spring hose 16. The filter device 14 is installed on the inner walls of both sides of the dyeing tank 3, which is responsible for filtering impurities in the dye solution to prevent problems such as nozzle clogging. The water pump 15 transmits the filtered dye solution to the dyeing nozzle 27 through the spring hose 16 for cyclic spraying and dyeing, ensuring that the dye solution can form a closed cycle within the system.

[0023] In particular, the present invention also includes a dyeing-assisting mechanism, and each group of dyeing-assisting mechanisms includes a mounting shell 22, a second motor 24, a fixed seat 25, a rotating seat 26, a dyeing nozzle 27 and a rotating rod 28. A mounting shell 22 is provided in the dyeing pool 3, and the fixed seat 25 is fixedly connected to the inner surface of the mounting shell 22. One end of the rotating rod 28 movably passes through one side end of the fixed seat 25, and the rotating seat 26 is fixedly connected to the circumferential surface of the rotating rod 28. The inner surface of the fixed seat 25 and the outer surface of the rotating seat 26 match each other. The second motor 24 is fixedly connected to one side end of the mounting shell 22, and the output end of the second motor 24 movably passes through one side end of the mounting shell 22 and is fixedly connected to the other end of the rotating rod 28. The dyeing nozzle 27 is fixedly connected to the lower end of the rotating seat 26.

[0024] The working principle of the dyeing aid mechanism is as follows: the second motor 24 is used as a power source and is fixedly connected to one side end of the mounting shell 22. Its output end moves through one side end of the mounting shell 22 and is fixedly connected to one end of the rotating rod 28. When the second motor 24 is running, it drives the rotating rod 28 to rotate. The dyeing nozzle 27 is fixedly connected to the lower end of the rotating seat 26. Since the rotating seat 26 can change its position as the rotating rod 28 rotates, the angle of the dyeing nozzle 27 can also be dynamically adjusted as needed. This allows the dyeing nozzle 27 to flexibly adjust the spray direction and coverage range according to actual dyeing needs, ensuring that the dye can be evenly distributed on the entire fabric surface. The dyeing aid mechanism works in coordination, and by controlling the start and stop of the second motor 24 and the rotation speed, the position and angle of each dyeing nozzle 27 can be accurately adjusted.

[0025] It should be noted that the upper inner walls of the two mounting shells 22 are fixedly connected with a plurality of connecting seats 31, the outer surface of the rotating rod 28 is sleeved with a supporting ring 32, the inner surfaces of the plurality of connecting seats 31 and the outer surfaces of the two supporting rings 32 are rotatably connected through a rotating shaft, one side end of the dyeing tank 3 is fixedly connected with a fixing shell 6, the inner surface of the fixing shell 6 is fixedly connected with a first motor 18, the inner wall of one side of the fixing frame 17 is rotatably connected with a bidirectional screw rod 19 through a bearing, the output end of the first motor 18 movably passes through the inner wall of one side of the dyeing tank 3 and is fixedly connected with one end of the bidirectional screw rod 19, the outer surface of the bidirectional screw rod 19 is threadedly connected with two nuts 21, the two mounting shells 22 are respectively fixedly connected to the circumferential surfaces of the two nuts 21, the inner walls on both sides of the fixing frame 17 are fixedly connected with two limiting rods 20, the two mounting shells 22 are respectively slidably connected to the circumferential surfaces of the two limiting rods 20, and the plurality of connecting seats 31 are set The two supporting rings 32 are installed and fixed in conjunction with the internal rotating shaft. The supporting ring 32 is arranged against one end of the rotating seat 26 away from the dyeing nozzle 27. The supporting ring 32 can play a role of elastic support for the rotating seat 26 through deformation, thereby providing auxiliary support for the dyeing nozzle 27. The internal first motor 18 is installed and fixed according to the set fixed shell 6, and the output end of the first motor 18 and the bidirectional screw rod 19 are fixed. When the first motor 18 is started, the bidirectional screw rod 19 is driven to rotate, and at the same time, the two nuts 21 are driven to slide left and right according to the rotation direction of the bidirectional screw rod 19. The two mounting seats 22 are respectively fixed on the surfaces of the two nuts 21, so that the two mounting seats 22 are driven to slide on the surfaces of the two limit rods 20 under the action of force, which plays a role of limiting the two sliding mounting seats 22, thereby driving the dyeing auxiliary mechanism to move left and right.

[0026] In the present invention, a sedimentation tank 12 is provided at the bottom of the dyeing tank 3, and a filter plate 13 is slidably connected to the upper end of the sedimentation tank 12. A plurality of fixing holes 30 are provided on the inner surface of the sedimentation tank 12. A plurality of drain pipes 4 are provided in the sedimentation tank 12, and one end of the drain pipes 4 passes through the sedimentation tank 12 and the dyeing tank 3 and extends to the outside of the dyeing tank 3. An electric valve 5 is provided on the drain pipes 4. The sedimentation tank 12 allows larger particles in the wastewater to settle to the bottom by gravity to achieve preliminary solid-liquid separation. The filter plate 13 is located on the outer surface of the sedimentation tank 12 to further filter fine particles in the wastewater and improve the water quality cleanliness. The electric valve 5 is installed on the outer surface of the drain pipe 4 to control the discharge amount of wastewater, which helps to optimize the operation efficiency of the entire system. The fixing holes 30 are provided on the inner surface of the sedimentation tank 12 to facilitate disassembly and cleaning of the internal structure of the sedimentation tank 12. The protective seat 29 provides a limiting and supporting function for the internal rotating rod 28 to reduce the risk of damage caused by external impact or misoperation. The base 2 provides a solid support foundation for the entire device to ensure the stability of the equipment during operation.

[0027] In particular, in the present invention, the filtering mechanism 14 is divided into two groups and cooperates with two dyeing nozzles 27. The filtering mechanism 14 includes a water pump 15, a filter shell 1401, two filter screens 1402 and a spring hose 16. The water pump 15 is fixedly connected to the inner wall of one side of the dyeing tank 3. The filter shell 1401 is arranged on the lower inner wall of the sedimentation tank 12. The two filter screens 1402 are both arranged inside the filter shell 1401. The two ends of one spring hose 16 are respectively connected and communicated with one end of the water inlet of the water pump 15 and the filter shell 1401, and the two ends of the other spring hose 16 are respectively connected and communicated with one end of the water outlet of the water pump 15 and the dyeing nozzle 27.

[0028] The working principle of the filtering mechanism is as follows: the two filter screens 1402 arranged inside are contained and protected by the filter shell 1401, and the dyeing liquid in the sedimentation tank 12 flows into the filter shell 1401 at the same time, and the inflowing dyeing liquid is filtered twice according to the two filter screens 1402 to prevent the impurities in the dyeing liquid from clogging the dyeing nozzle 27, and the filter shell 14, the water pump 15 and the dyeing nozzle 27 are connected by two fixed spring hoses 16. When the water pump 15 is started, the dyeing liquid in the filter shell 14 is transmitted to the inside of the dyeing nozzle 27 for spraying. The working principle of the present invention is as follows: first, the cloth enters and leaves the dyeing tank 3 through the inlet and outlet 11 opened at the two side ends of the dyeing tank 3. During the dyeing process, the cloth passes through the path of the unpowered roller 7 and the powered roller 9 for supporting and guiding the cloth, pushing the cloth to smoothly enter and leave the dyeing area. By controlling the first motor 18 to rotate, the two nuts 21 on the surface of the screw rod 19 are driven to slide left and right, and at the same time, the auxiliary dyeing mechanism arranged on the lower side is driven to adjust the position. During the dyeing process, the rotation of the two second motors 24 is controlled to drive the two rotating rods 28 to rotate respectively, thereby driving the rotating seat 26 and the dyeing nozzle 27 fixed on the lower side to perform multi-angle adjustment, flexibly adjusting the spraying direction and coverage range, and ensuring that the dye can be evenly distributed on the entire cloth surface.

[0029] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
