[0016] A multi-stage yarn dyeing device, such as Figure 1 As shown, it includes a yarn bobbin placement section, a dyeing section, and a steam fixing section; The yarn bobbin placement part includes a pay-off assembly and a take-up assembly. The pay-off assembly and the take-up assembly each include a group of vertical block groups. Each group of vertical block groups includes two vertical blocks 1 placed in front and behind. A rotating motor is fixedly installed in front of the vertical block 1 at the rear, and a support shaft 2 is fixedly installed at the front end of the output shaft of the rotating motor. An array of screw hole groups 3 is provided on the support shaft 2. Each group of screw hole groups 3 consists of two screw holes. The screw hole threads are used to install a threaded rod. An auxiliary support assembly is installed on the vertical block 1 at the front, and the auxiliary support assembly supports the support shaft 2.

[0017] After the yarn bobbin is placed on a set of screw hole groups 3, the two screw holes in the screw hole group 3 are respectively located at the front and rear ends of the yarn bobbin, and several yarn bobbins are sequentially mounted on the support shaft 2 from the front end of the support shaft 2. The yarn bobbin installed on the pay-off assembly is loaded with yarn, and the yarn bobbin installed on the take-up assembly is a blank bobbin, so that each yarn bobbin is located between two screw holes in a set of screw hole groups 3. Then the threaded rod is installed, and the threaded rod passes through the support shaft 2 and is exposed, that is, the front and rear threaded rods limit the yarn bobbin. After installation, the auxiliary support group The component is connected to the support shaft 2 to support the support shaft 2, so that the force is more uniform and the connection is more secure. The yarn on the yarn bobbin is then passed through the dyeing section and the steaming and fixing section in turn, and finally wound onto the yarn bobbin on the take-up assembly. The pay-off operation is then performed on the pay-off assembly, and the take-up assembly performs the take-up operation. The yarn is dyed in the dyeing section and then fixed in the steaming and fixing section. The yarn is dyed. During the dyeing process, multiple strands of different colors can be dyed at the same time to obtain yarns of different colors.

[0018] Specifically, the auxiliary support assembly described in this embodiment includes a through hole opened in front of the vertical block 1 located in the front, and the support rod 4 is slidably installed in the through hole. The outer wall of the rear end of the support rod 4 is opened with an external thread, and the front end of the support shaft 2 is opened with a threaded hole. The rear end of the support rod 4 can be inserted into the threaded hole, and the external thread cooperates with the thread of the threaded hole.

[0019] After the rear end of the support rod 4 is inserted into the threaded hole, the front end of the support rod 4 is still located in the through hole. After the yarn bobbin is installed, the support rod 4 is slid toward the support shaft 2 so that the rear end of the support rod 4 is inserted into the threaded hole, and the external thread on the support rod 4 is matched with the thread of the threaded hole. At this time, the front end of the support rod 4 continues to be located in the through hole. Through the support of the support rod 4, the support shaft 2 can be stably stressed, the structure is firm, and it is more stable during use.

[0020] Furthermore, the dyeing section described in this embodiment includes a long box 5, the top surface of the long box 5 is open, and several legs are fixedly installed at the bottom end of the long box 5. Several long boxes 6 are installed in the long box 5, and an opening is opened on the top surface of the long box 6. A cover body is hingedly installed at the opening. A frame 7 is fixedly installed on one side of the top surface of the long box 6. The upper and lower ends of the frame 7 are through-connected, and the bottom end of the frame 7 is connected to the interior of the long box 6. A horizontal plate 8 is fixedly installed in the frame 7, and several connecting pipes are fixedly installed on the horizontal plate 8. A nozzle is fixedly installed at the bottom end of the connecting pipe, and the top end of the connecting pipe is fixedly connected to the dye delivery pipe. A first guide member and a second guide member are installed in the long box 6, and an overflow pipe 9 is installed on the inner wall of the rear end of the long box 6. The inner walls on both sides of the long box 5 and the inner walls on both sides of the long box 6 are provided with through grooves, and the through grooves are located on the same horizontal plane.

[0021] The dye delivery pipe is connected to the dye storage device, and dyes of different colors are delivered to different dye delivery pipes. The overflow pipe is connected to the recovery equipment. A heating wire is embedded in the long box 6, and the heating wire is connected to the outside. The heating wire heats the dye in the long box 6 to maintain the temperature of the dye and prevent the dye from cooling. A temperature sensor is installed in the long box 6 to detect the temperature inside the long box 6.

[0022] like Figure 1 As shown, the yarn enters the long box 6 from the left side through slot of the long box 5 and the left side through slot of the long box 6, and then passes through the right side through slot of the long box 6 and the right side through slot of the long box 5 under the guidance of the first guide member and the second guide member. The dye sprayed by the nozzle falls onto the yarn, and the dye is stored in the long box 6. The yarn is soaked in the dye, and the yarn is dyed by the dual operation of spraying and soaking to improve the dyeing efficiency; when the height of the dye is higher than the height of the overflow pipe 9, excess dye flows out of the overflow pipe 9 to control the volume of the dye in the long box 6.

[0023] Furthermore, the first guide member described in this embodiment includes two first guide rollers 10, which are respectively located on both sides of the long box 6, and the front and rear ends of the first guide rollers 10 are movably connected to the front and rear inner walls of the long box 6.

[0024] The height of the first guide roller 10 is close to the height of the through groove. The yarn enters the long box 6 and contacts the first guide roller 10, which prevents the yarn from contacting the through groove and causing wear.

[0025] Furthermore, the second guide member described in this embodiment includes two second guide rollers 11, which are located on either side of the elongated box 6 and between the two first guide rollers 10. The front and rear ends of the second guide rollers 11 are movably connected to the front and rear inner walls of the elongated box 6, respectively, and the height of the second guide rollers is lower than that of the first guide rollers. The lowest position of the dye is higher than the height of the second guide rollers 11, and the yarn contacts the bottom ends of the second guide rollers. The yarn is then immersed in the dye due to the restriction of the second guide rollers.

[0026] Furthermore, the steaming and dye-fixing section of this embodiment includes a steam box 12. Several legs are fixedly mounted at the bottom of the steam box 12. Through-holes are defined on both sides of the outer wall of the steam box 12. Several rollers are movably mounted within the steam box 12. A steam delivery pipe is fixedly connected to the top of the steam box 12, and a discharge pipe is fixedly connected to the bottom of the steam box 12. The steam delivery pipe is connected to a steam generator. The dyed yarn passes through the through-holes and contacts the top of the rollers. The yarn then exits the steam box 12 and undergoes a dye-fixing operation through steaming.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
