[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figure 2 , Figure 4 and Figure 5, an embodiment provided by the present utility model: a precise chemical metering and filling device, including a conveyor belt 1. A fixed frame 2 is fixedly connected to the upper part of the conveyor belt 1. A fixed box 4 is fixedly connected to the left part of the fixed frame 2. A motor 1 5 is fixedly connected to the front part of the fixed box 4. The output end of the motor 1 5 is fixedly connected to a gear 6. The right part of the gear 6 is meshed and connected to a rack plate 7. Both sides inside the fixed frame 2 are slidably connected with connecting plates 8. The upper part of the left connecting plate 8 is fixedly connected to the rack plate 7. Limiting components are fixedly connected to both sides of the left connecting plate 8. The limiting components are used to limit the connecting plate 8. Support frames 12 are fixedly connected to the opposite sides of the two connecting plates 8. Electric push rods 13 are fixedly connected to both outer sides of the support frames 12. The output ends of the two electric push rods 13 are fixedly connected to movable plates 14. Connecting columns 15 are fixedly connected to the opposite sides of the two movable plates 14. The other ends of the connecting columns 15 are fixedly connected to clamping members 16.

The limiting columns 29 are slidably connected to the inside of the support frame 12.

[0025] First, the containers to be filled need to be placed inside the special fixed frame 3. Once the containers are in place, start the conveyor belt 1 to make the containers move along a predetermined path. As the conveyor belt 1 starts slowly, the containers will gradually move to the position below the support frame 12. At this time, activate the motor 1 5. The output end of the motor 1 5 starts to rotate, thereby driving the gear 6 to rotate regularly. The rotation of the gear 6 will cause the rack plate 7 to move along a specific trajectory. The movement of the rack plate 7 will cause the connecting plate 8 to slide along the set path. The sliding of the connecting plate 8 drives the slider 9 to slide smoothly on the outside of the slide rod 10. The sliding of the slider 9 acts on the connecting plate 8, thereby causing the support frame 12 to move downward. When the support frame 12 drives the clamping member 16 to reach the periphery of the container during the movement, then start the two electric push rods 13. The output ends of the electric push rods 13 start to act, pushing the movable plate 14 to move along the established trajectory. The movement of the movable plate 14 will drive the connecting column 15 and the clamping member 16 to move together. The clamping member 16 will push the limiting column 29 to slide inside the electric push rod 13 during the movement. In this way, the two clamping members 16 will gradually approach and finally firmly fix the container.

[0026] Refer to Figures 1-3, the upper part of the fixing frame 2 is fixedly connected with a tank body 17, the inside of the tank body 17 is fixedly connected with an inner tank 23, the upper part of the inner tank 23 is fixedly connected with a second motor 18, the output end of the second motor 18 is fixedly connected with a rotating shaft 19, the outside of the rotating shaft 19 is fixedly connected with a limiting frame 20, the inside of the limiting frame 20 is rotatably connected with a stirring blade 21, the inside of the tank body 17 is fixedly connected with a heating pipe 24, the outside of the tank body 17 is fixedly connected with a water inlet pipe and a water outlet pipe, the upper part of the fixing frame 2 is fixedly connected with a feeding pump 25, the input end of the feeding pump 25 is fixedly connected with the inner tank 23, the output end of the feeding pump 25 is fixedly connected with a feeding hose 26, the other end of the feeding hose 26 is fixedly connected with a fixed pipe 27, the opposite sides of the two connecting plates 8 are fixedly connected with cross plates 11, the inside of the cross plates 11 are fixedly connected with discharge pipes 28, the upper part of the discharge pipes 28 is fixedly connected with the fixed pipe 27, the upper part of the conveyor belt 1 is fixedly connected with fixing frames 3 around the perimeter, the support frame 12 is arranged on the upper part of the fixing frame 3, the discharge pipe 28 is arranged on the upper part of the support frame 12, one side of each of the plurality of limiting frames 20 close to the inner wall of the inner tank 23 is fixedly connected with a scraping plate 22, and each of the plurality of scraping plates 22 is slidably connected to the inside of the inner tank 23.

[0027] Through the water inlet pipe provided on the tank body 17, the required amount of water can be injected into the inside of the tank body 17. Subsequently, using the heat energy of the heating pipe 24, these waters are heated. After being heated, the temperature of the water rises, which can effectively transfer heat to the inner tank 23, and then heat the chemicals stored in the inner tank 23. This heating process helps to increase the temperature of the chemicals and make them reach the ideal reaction conditions. At the same time, start the second motor 18. The operation of the second motor 18 outputs power to the rotating shaft 19. The rotating shaft 19 starts to rotate under the drive of the motor. Its rotational movement is transmitted to the limiting frame 20, causing the limiting frame 20 to also start to rotate. During the rotation of the limiting frame 20, the stirring blade 21 inside is driven to perform a corresponding rotational movement. The rotation of the stirring blade 21 can effectively stir and mix the materials in the tank, ensuring that the materials are evenly heated during the heating process and avoiding the occurrence of local overheating or insufficient heating. In addition, while the limiting frame 20 is rotating, it also drives the rotation of the scraping plate 22. The rotation of the scraping plate 22 acts on the inner wall of the inner tank 23, which can scrape off the materials that may adhere to the inner wall, keep the inner wall clean, and avoid the materials affecting the heating effect or causing coking during the heating process.

[0028] Working principle: First, place the container to be filled inside the fixed frame 3, start the conveyor belt 1 to move the container. When the container moves to the lower part of the support frame 12, start the first motor 5. The output end of the first motor 5 drives the gear 6 to rotate. The rotation of the gear 6 drives the rack plate 7 to move. When the rack plate 7 moves, it drives the connecting plate 8 to move. The movement of the connecting plate 8 drives the slider 9 to slide outside the slide bar 10. Under the action of the slider 9, the connecting plate 8 drives the support frame 12 to move downward. When the support frame 12 drives the clamping member 16 to move to the outside of the container, start the two electric push rods 13. The output ends of the electric push rods 13 drive the movable plate 14 to move. The movement of the movable plate 14 drives the connecting column 15 and the clamping member 16 to move. When the clamping member 16 moves, it drives the limiting column 29 to slide inside the electric push rod 13, so that the two clamping members 16 approach each other to fix the container. This realizes effective clamping and fixing of the container, can prevent chemicals from overflowing due to the movement or shaking of the container, can maintain stability, speed up the filling speed, and improve production efficiency. Add water into the tank body 17 through the water inlet pipe. Under the action of the heating pipe 24, the water is heated. The heated water can heat the inner tank 23, thereby heating the chemicals inside the inner tank 23. At the same time, start the second motor 18. The output end of the second motor 18 drives the rotating shaft 19 to rotate. The rotation of the rotating shaft 19 drives the limiting frame 20 to rotate. While the limiting frame 20 rotates, the stirring blades 21 rotate inside the limiting frame 20 to stir the internal materials. This realizes effective stirring and heating of the solution, can increase the kinetic energy of the pinacolone molecules, make them more easily dissolve in the solvent, and improve the uniformity of the solution.
