Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 An embodiment of this utility model provides an automatic mixing tank for oxidized starch sizing solution, including a shell 1.

At the same time, it drives the gear 4 to rotate through the meshing of the gear 4. At the same time, the elastic function of the spring 10 reduces the impact force of the protruding tooth 11. The metering box 2 has a through hole 12 inside. The through hole 12 is a single channel and can only correspond to one metering groove 5, thus achieving the metering effect. The bottom of the metering box 2 is fixedly connected to the conveying pipe 13. The conveying pipe 13 is used to discharge the metered oxidized starch sizing solution into the interior of the shell 1 to prepare for subsequent stirring. The top of the shell 1 is fixedly connected to the cleaning component.

[0035] Reference Figure 1 , Figure 4 and Figure 5The cleaning component includes a second motor 14, which serves as the power source for the cleaning component. A drive rod 15 is fixedly connected to the drive end of the second motor 14. The drive rod 15 can rotate by receiving force from the second motor 14. Multiple connecting rings 16 are fixedly connected to the outside of the drive rod 15. When the drive rod 15 rotates, it can drive a connecting plate 17 to rotate through the connecting rings 16. Two connecting plates 17 are fixedly connected to the outside of the connecting rings 16, providing support for the rotating plate 18. One of the connecting plates 17 has a front and rear... Rotating plates 18 are rotatably connected to both sides, providing support for the connecting block 19 and T-shaped block 20 above. The top of one rotating plate 18 is rotatably connected to the connecting block 19, which provides space for the T-shaped groove 21. The top of the other rotating plate 18 is rotatably connected to the T-shaped block 20, which can be inserted into the inner wall of the T-shaped groove 21, so that the outside of the T-shaped block 20 and the connecting block 19 can be smoothly engaged with the inner wall of the connecting groove 27, thereby completing the splicing. Cleaning components can be added as needed.

[0036] The connecting block 19 has a T-slot 21 inside, which is used to cooperate with the T-block 20 to complete the connection between the T-block 20 and the connecting block 19. A connecting box 22 is fixedly connected to the right side of the connecting plate 17. The connecting box 22 provides space for the connecting groove 23.

The connecting plate 17 has a connecting groove 27 inside. The T-shaped block 20 can be inserted into the inner wall of the T-shaped groove 21, so that the outside of the T-shaped block 20 and the connecting block 19 can be smoothly engaged with the inner wall of the connecting groove 27, thereby completing the splicing. Cleaning components can be added as needed.

[0037] Reference Figure 2 , Figure 4 and Figure 5 The outer surface of the protruding tooth 11 is slidably connected to the inside of the driven groove 9. The driven groove 9 provides a limiting and guiding function for the protruding tooth 11. The outer surface of the protruding tooth 11 is meshed with the outer surface of the gear 4. Through the meshing connection, the protruding tooth 11 can drive the gear 4 to rotate. The bottom of the conveying pipe 13 is fixedly connected to the top of the housing 1. The conveying pipe 13 can transport the metered oxidized starch sizing solution to the inside of the housing 1. The through hole 12 corresponds to one of the metering grooves 5. When the gear 4 rotates, only one metering groove 5 can correspond to the through hole 12, and then the oxidized starch sizing solution flows down, thereby achieving the metering effect.

[0038] The outer side of T-block 20 contacts the inner wall of T-slot 21. T-block 20 is used to snap into the inner wall of T-slot 21, thereby completing the splicing and fixing of T-block 20 and connecting block 19. The outer side of T-block 20 and the outer side of connecting block 19 respectively contact the inner wall of connecting groove 27. After the outer side of T-block 20 and connecting block 19 are engaged, they can be smoothly snapped into the interior of connecting groove 27, thereby completing the limiting and fixing of rotating plate 18, thereby completing the limiting and fixing of connecting plate 17, and thus achieving splicing. The outer side of cleaning plate 26 is slidably connected to the interior of connecting groove 23. Connecting groove 23 provides limiting and guiding function for cleaning plate 26. The opposite sides of multiple cleaning plates 26 contact the inner wall of housing 1. Cleaning plates 26 can clean the inner wall of housing 1. Multiple sets of rotating plates 18 are staggered. The staggered distribution can better complete the splicing. The bottom of motor 2 14 is fixedly connected to the top of housing 1. Housing 1 provides fixing and support for motor 2 14.

[0039] Working principle: During use, when quantitative mixing of oxidized starch sizing solution is required, motor 6 drives cam 7 to rotate, which in turn drives connecting blocks 8 on both sides to rotate synchronously. The protruding teeth 11 inside connecting block 8, supported by spring 10, mesh with gear 4, causing gear 4 to rotate intermittently. When the quantitative groove 5 aligns with the through hole 12 at the bottom of the quantitative box 2, the oxidized starch sizing solution flows through the through hole 12 into the conveying pipe 13 and then into the housing 1. Since only one quantitative groove 5 corresponds to the through hole 12 at a time, and the volume of the quantitative groove 5 is fixed, precise quantitative delivery is achieved. The buffering effect of spring 10 reduces the impact force between the protruding teeth 11 and gear 4, extending service life.

[0040] When the inner wall of the shell 1 needs to be cleaned, the motor 14 is started, and the drive rod 15 drives the connecting plate 17 to rotate through the connecting ring 16, so that the cleaning plate 26 slides along the inner wall of the shell 1 to scrape off the adhering material. The rotating plate 18 is spliced ​​by the engagement of the T-block 20 and the connecting block 19, and the spring 24 provides elastic support for the cleaning plate 26 to ensure that the cleaning plate 26 fits tightly with the tank wall. Multiple sets of rotating plates 18 are staggered to facilitate splicing and installation. The number of splices can be adjusted through the connecting groove 27 to flexibly adapt to different tank sizes. The entire cleaning process is automated, which improves cleaning efficiency and hygiene standards.
