Near-infrared dyes have unique absorption and emission characteristics, giving them broad application potential in multiple fields. These dyes usually have high fluorescence intensity and photostability, and can maintain stable performance in complex environments.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] See also Figure 1-4 , the utility model provides a technical solution:
[0025] A near-infrared dye preparation and mixing device includes a reactor 1, a fixing box 2 is fixedly connected to the top of the reactor 1, and a plurality of injection holes 3 are installed on the top of the reactor 1. The device also includes:
[0026] A stirring assembly, located inside the reactor 1, for fully mixing the near-infrared dye inside the reactor 1;
[0027] The driving assembly is located inside the fixed box 2 and is used to drive the stirring assembly to stir in two directions simultaneously;
[0028] The heating component is located on the outer surface of the reactor 1 and is used to provide the temperature required for the reaction to ensure that the reaction is carried out at a suitable temperature. The required near-infrared dye raw material is injected into the reactor 1 through the injection hole 3.
[0029] Furthermore, the stirring assembly includes a first rotating shaft 8, a second rotating shaft 9, a connecting ring 10, a stirring blade 11 and a stirring shaft 12. The bottom of the fixed box 2 is rotatably connected to the first rotating shaft 8, and the second rotating shaft 9 is sleeved inside the first rotating shaft 8. The bottoms of the first rotating shaft 8 and the second rotating shaft 9 are fixedly connected to the connecting ring 10. The two connecting rings 10 are distributed up and down. The outer surfaces of the two connecting rings 10 are fixedly connected to multiple annular equidistant stirring shafts 12. The outer surfaces of the multiple stirring shafts 12 are fixedly connected to multiple equidistant stirring blades 11. The bottoms of the first rotating shaft 8 and the second rotating shaft 9 are fixedly connected to the connecting ring 10, and the outer surface of the connecting ring 10 is fixedly connected to multiple annular equidistant stirring shafts 12. When the first rotating shaft 8 and the second rotating shaft 9 rotate, the stirring shaft 12 and the stirring blades 11 thereon will be driven to rotate in opposite directions, thereby fully mixing the near-infrared dye in the reactor 1.
[0030] Furthermore, the driving assembly includes a driving motor 5, a support frame 13, a driving bevel gear 14, a first bevel gear 15 and a second bevel gear 16. The interior of the fixed box 2 is fixedly connected to the support frame 13, and the outer surface of the support frame 13 is rotatably connected to the driving bevel gear 14. The outer surface of the driving bevel gear 14 is vertically meshed with the first bevel gear 15 and the second bevel gear 16. The outer surface of the fixed box 2 is fixedly installed with the driving motor 5, and the output end of the driving motor 5 passes through the fixed box 2 and is fixedly connected to the driving bevel gear 14. When the driving motor 5 is started, its output end drives the driving bevel gear 14 to rotate, and the driving bevel gear 14 is vertically meshed with the first bevel gear 15 and the second bevel gear 16 at the same time. Therefore, when the driving bevel gear 14 rotates, it will drive the first bevel gear 15 and the second bevel gear 16 to rotate in opposite directions respectively. The first bevel gear 15 is fixedly connected to the second rotating shaft 9, so the second rotating shaft 9 will rotate with the rotation of the first bevel gear 15.
[0031] Furthermore, the first bevel gear 15 is located above the second bevel gear 16, the first bevel gear 15 is rotatably connected to the top inner wall of the fixed box 2 and is fixedly connected to the second rotating shaft 9, the second bevel gear 16 is rotatably connected to the top of the reactor 1 and is fixedly connected to the first rotating shaft 8, and the second bevel gear 16 is fixedly connected to the first rotating shaft 8, so that the first rotating shaft 8 will also rotate with the rotation of the second bevel gear 16. Since the rotation directions of the first bevel gear 15 and the second bevel gear 16 are opposite, the first rotating shaft 8 and the second rotating shaft 9 will rotate in opposite directions.
[0032] Furthermore, the heating component includes a heating power supply 4 and a heating tube 7. The inner wall of the reactor 1 is wrapped with the heating tube 7, and the heating tube 7 is distributed in a spiral shape. The outer surface of the reactor 1 is fixedly installed with a heating power supply 4, and the heating power supply 4 is electrically connected to the heating tube 7. After the heating power supply 4 is started, the current passes through the heating tube 7 to generate heat. The heating tube 7 is distributed in a spiral shape on the inner wall of the reactor 1 to ensure that the heat is evenly transferred to the inside of the reactor 1, providing a suitable temperature environment for the dye reaction.
[0033] Furthermore, a steam inlet pipe 6 is fixedly installed on the outer surface of the reactor 1, and steam is introduced into the reactor 1 through the steam inlet pipe 6 to assist in heating or adjust the reaction environment.
[0034] Working principle: When the staff needs to use the near-infrared dye to prepare a mixing device, the required near-infrared dye raw materials are injected into the reactor 1 through the injection hole 3, the heating power supply 4 is turned on to provide power for the heating component, and steam can be introduced into the reactor 1 through the steam inlet pipe 6 to assist in heating or adjust the reaction environment. After the heating power supply 4 is started, the current passes through the heating tube 7 to generate heat. The heating tube 7 is spirally distributed on the inner wall of the reactor 1 to ensure that the heat is evenly transferred to the inside of the reactor 1, providing a suitable temperature environment for the dye reaction. The driving motor 5 is started, and its output end drives the active bevel gear 14 to rotate. The active bevel gear 14 is vertically meshed with the first bevel gear 15 and the second bevel gear 16 at the same time. Therefore, when the active bevel gear 14 rotates, it will drive the first bevel gear 15 and the second bevel gear 16 to rotate in opposite directions respectively. The first bevel gear 15 is fixedly connected to the second rotating shaft 9, so the second rotating shaft The driving shaft 9 will rotate with the rotation of the first bevel gear 15, and the second bevel gear 16 is fixedly connected to the first rotating shaft 8, so that the first rotating shaft 8 will also rotate with the rotation of the second bevel gear 16. Since the rotation directions of the first bevel gear 15 and the second bevel gear 16 are opposite, the first rotating shaft 8 and the second rotating shaft 9 will rotate in opposite directions. The bottoms of the first rotating shaft 8 and the second rotating shaft 9 are fixedly connected with a connecting ring 10, and the outer surface of the connecting ring 10 is fixedly connected with a plurality of annular stirring shafts 12 distributed equidistantly. When the first rotating shaft 8 and the second rotating shaft 9 rotate, the stirring shaft 12 and the stirring blades 11 thereon will be driven to rotate in opposite directions, thereby fully mixing the near-infrared dye in the reactor 1. When the dye is fully mixed at an appropriate temperature and reaches a predetermined reaction time, the reaction is completed. At this time, the heating power supply 4 and the drive motor 5 can be turned off to stop heating and stirring.
