[0028] Example 1: As Figures 1-3 ,include:

[0029] A dye bin 110 is fixedly installed on the bottom inner wall of a workbench 100.

[0030] The take-up and unwinding assembly has two sets. The take-up and unwinding assembly includes bushings 220, which are arranged in pairs on the left and right sides. The inner wall of the bushing 220 is rotatably connected to the wire roller 300.

[0031] The spray dyeing assembly includes a self-priming pump 500 and a nozzle 560. The output end of the self-priming pump 500 is connected to the nozzle 560, and the nozzle 560 faces the yarn sleeve.

[0032] The specific application scenario of this embodiment is as follows: The dye bin 110, which is fixedly installed on the inner wall of the bottom, is used to store dye. In the two sets of take-up and unwinding assemblies, the bushings 220 are arranged in pairs on the left and right sides. The yarn roller 300 rotates on the inner wall of the bushing 220 to realize the unwinding and take-up of the yarn bundle. The self-priming pump 500 of the spray dyeing assembly draws the dye from the dye bin 110 and applies the dye to the yarn bundle in the form of a spray through the nozzle 560 connected to the output end, thereby realizing the dyeing operation of the yarn bundle. This embodiment constructs the basic architecture of the yarn bundle dyeing equipment. The take-up and unwinding assembly provides the basis for the transmission of the yarn bundle, and the spray dyeing assembly completes the dyeing function. The nozzle 560 includes an electric heating tube, which generates heat by passing electricity through the internal resistor to circulate and heat the dye flowing through it.

[0033] Example 2: Figures 1-3 Two sets of winding and unwinding assemblies are fixedly installed at the top of both ends of the workbench 100. These assemblies are used to unwind the yarn sheath to be dyed and to wind up the dyed yarn sheath. Each winding and unwinding assembly includes a bearing seat 200, which is fixedly installed on the top of the workbench 100. A first arc-shaped cover plate 210 is inserted into the top of the bearing seat 200. First screws 211 are fixedly installed at the top of both ends of the bearing seat 200. The first screws 211 pass through the inner wall of the first arc-shaped cover plate 210 and are fixedly installed by first horn nuts. The outer wall of the bushing 220 is rotated by a hinge. The second arc-shaped cover plate 230 is dynamically connected. A U-shaped notch 231 is opened on the outer wall of the second arc-shaped cover plate 230 away from the hinge. The second screw 221 is fixedly installed on the outer wall of the bushing 220. The second arc-shaped cover plate 230 flips to cover and fix the end of the wire roller 300. The U-shaped notch 231 on the outside of the second arc-shaped cover plate 230 is engaged with the second screw 221. The top of the second screw 221 is threadedly connected to the second horn nut 222. The servo motor 240 is fixedly installed on the outer wall of the bearing seat 200. The outer wall of the output shaft of the servo motor 240 is connected to the bushing 220 for transmission.

[0034] The specific application scenario of this embodiment is as follows: the unwinding and winding components at the top of both ends of the workbench 100 are responsible for the unwinding and winding of the yarn sleeve. The bearing seat 200 is fixed to the top of the workbench 100. The second arc-shaped cover plate 230 on the outer wall of the bushing 220 rotates through a hinge. The U-shaped notch 231 cooperates with the second screw 221. The second horn nut 222 is used to firmly fix the end of the yarn roller 300, ensuring that the yarn roller 300 is stable and does not deviate during rotation. The servo motor 240 is fixed to the outer wall of the bearing seat 200. Its output shaft is connected to the bushing 220 for transmission, providing power for the rotation of the yarn roller 300. It precisely controls the unwinding and winding speed and tension of the yarn sleeve, ensuring stable and efficient transmission of the yarn sleeve during the dyeing process.

[0035] Example 3: Figure 1 and Figure 2 Tensioning assemblies are installed on the outer walls of the workbench 100 near the input and output ends of the dye bin 110. The tensioning assemblies include a base 400, which is fixedly installed on the top outer wall of the workbench 100. The top of the base 400 is connected to the roller seat 410 via a telescopic rod 420. A spring is sleeved on the outer wall of the telescopic rod 420. The two ends of the spring are connected to the roller seat 410 and the base 400. The inner wall of the roller seat 410 is rotatably connected to the tensioning roller 430 via a bearing. The inner wall of the dye bin 110 is rotatably connected to the guide roller 120 via a bearing. Several guide rollers 120 are provided. The guide rollers 120 are used to guide and convey the yarn sleeve to the tensioning roller 430 on the output side of the dye bin 110.

[0036] The specific application scenario of this embodiment is as follows: The tensioning components installed on the outer walls of the workbench 100 near the input and output ends of the dye chamber 110 mainly function to maintain the tension stability of the yarn sleeve during the transmission process. The base 400 is fixed to the top of the workbench 100, and the top is connected to the roller seat 410 through the telescopic rod 420. The spring sleeved on the outer wall of the telescopic rod 420 pushes the roller seat 410 up and down by its own telescopic deformation when the tension of the yarn sleeve changes, thereby driving the tension roller 430 to adjust the pressure on the yarn sleeve, thereby maintaining the constant tension of the yarn sleeve. Several guide rollers 120 on the inner wall of the dye chamber 110 provide guidance for the yarn sleeve by rotating the bearings, guiding the yarn sleeve to be accurately transported from the input end of the dye chamber 110 to the tension roller 430 on the output end side, ensuring the stability of the transmission path of the yarn sleeve before and after dyeing, and avoiding problems such as entanglement and deviation.

[0037] Example 4: Figure 4 and Figure 5A self-priming pump 500 is fixedly installed on the outer wall of the dye chamber 110.

The output end of the second conduit 520 is fixedly connected to a third conduit 540. The two ends of the third conduit 540 are respectively connected to a nozzle 560 via a fourth conduit 550.

[0038] The specific application scenario of this embodiment is as follows: The self-priming pump 500 is fixed on the outer wall of the dye chamber 110. Its input end is connected to the inner wall of the dye chamber 110 through the first conduit 510 to extract the dye from the dye chamber 110. The heater 530 installed on the second conduit 520 connected to the output end can heat the extracted dye to make the dye reach a suitable dyeing temperature, thereby improving the dyeing effect and quality. The heated dye is transferred through the second conduit 520 to the third conduit 540, and then distributed to the nozzle 560 through the fourth conduit 550. Finally, it is sprayed out from the nozzle 560 at a suitable temperature and pressure, acting evenly on the yarn sheath to complete the dyeing process. This embodiment focuses on ensuring the dye delivery, heating and distribution process, providing a stable dye supply that meets the process requirements for dyeing the yarn sheath.

[0039] The working principle of this utility model is as follows: When used by those skilled in the art, after startup, the unwinding assembly, driven by the servo motor 240, drives the yarn roller 300 to unwind the yarn sleeve. The tensioning assembly cooperates with the guide roller 120 to ensure that the yarn sleeve is stably transmitted to the dye chamber 110. The self-priming pump 500 extracts the dye from the dye chamber 110 and delivers it through the first conduit 510 and the second conduit 520. During the process, the heater 530 heats the dye. Subsequently, the dye reaches the nozzle 560 through the third conduit 540 and the fourth conduit 550. The nozzle 560 sprays the heated dye onto the yarn sleeve to complete the dyeing. Finally, the unwinding assembly pulls the dyed yarn sleeve and is wound up by the winding end roller 300 to achieve automated dyeing.
