[0025] Refer to Figure 1 - Figure 5As shown in the figure, the present utility model provides a technical solution: a new type of high-speed dry powder mixing device, which includes a mixing cylinder 1. A discharge pipe 2 is installed at the bottom end of the mixing cylinder 1. A feed pipe 3 is installed on the right side of the mixing cylinder 1. A conveying pipe 4 is installed at the top end of the feed pipe 3. A rotating rod 5 is installed at the top end of the mixing cylinder 1. A rotating motor 6 is installed at the top end of the rotating rod 5. Two mixing plates 7 are installed on the surface of the rotating rod 5. An L-shaped plate 8 is installed on the left side of the conveying pipe 4. A fixing plate 9 is fixed at the top end of the L-shaped plate 8. An adjusting plate 10 is slidably connected inside the fixing plate 9. A first slot 11 is opened at the top end of the adjusting plate 10. Square slots 12 are opened at the front and rear ends of the first slot 11. A sliding slot 13 is opened on the surface of the conveying pipe 4. A flow-limiting plate 14 is slidably connected inside the sliding slot 13. One end of the flow-limiting plate 14 close to the adjusting plate 10 is fixedly connected to the adjusting plate 10. A fixing block 15 is fixed at the top end of the fixing plate 9. A second slot 16 is opened inside the fixing block 15. The number of the second slots 16 is two and a pressing plate 17 is slidably connected inside each of them. A elastic spring 18 is installed inside the second slot 16. One end of the elastic spring 18 close to the pressing plate 17 is fixedly connected to the pressing plate 17. A through slot 19 is opened at the top end of the fixing plate 9. The size of the through slot 19 is adapted to the square slot 12. A clamping block 20 is installed at the bottom end of the pressing plate 17. When the staff needs to adjust the flow rate of the material feeding, press the pressing plate 17 inward to move the clamping block 20 out of the square slot 12, so that the adjusting plate 10 is released from the limit. At this time, move the position of the adjusting plate 10 to move the flow-limiting plate 14 to a position suitable for the dry powder feeding. Then release the pressing plate 17. At this time, the elastic spring 18 drives the pressing plate 17 to quickly pop into the square slot 12 to limit the adjusting plate 10, so as to achieve the rapid control of the flow rate during the dry powder feeding, effectively improve the flow rate control during the mixing of various dry powders, and improve the accuracy during the proportioning.
[0026] Referring to Figure 4 As shown in the figure, in this implementation scheme: first sliding grooves 21 are opened on both sides inside the fixing block 15. First sliding blocks 22 are fixed on both sides of the pressing plate 17. The first sliding blocks 22 are slidably connected inside the first sliding grooves 21. Through the setting of the first sliding grooves 21 and the first sliding blocks 22, a stable limiting effect can be formed during the pressing or popping of the pressing plate 17, so that the pressing plate 17 moves more stably, thereby improving the adjusting effect of the flow-limiting plate 14.
[0027] Referring to Figure 6 As shown in the figure, in this implementation scheme: second sliding grooves 23 are opened on both sides inside the fixing plate 9. Second sliding blocks 24 are fixed on both sides of the adjusting plate 10. The second sliding blocks 24 are slidably connected inside the second sliding grooves 23. Through the setting of the second sliding grooves 23 and the second sliding blocks 24, the adjusting plate 10 can be limited when moving inside the fixing plate 9, preventing the adjusting plate 10 from being pulled off due to excessive pulling, thereby affecting the dry powder flow limiting.
[0028] Referring to Figure 6 as shown, in this embodiment: a reset spring 25 is fixed to one end of the adjusting plate 10 away from the conveying pipe 4, and the end of the reset spring 25 away from the adjusting plate 10 is fixed inside the fixing plate 9.

[0030] Referring to Figure 7 as shown, in this embodiment: an installation groove 26 is opened at one end of the mixing plate 7 close to the mixing cylinder 1. A cleaning plate 27 is slidably connected inside the installation groove 26. A connecting plate 28 is installed at the top of the mixing plate 7. A threaded rod 29 is threadedly connected inside the connecting plate 28. A rotating plate 30 is installed at one end of the threaded rod 29 close to the connecting plate 28. A limiting plate 31 is fixed to the top of the cleaning plate 27. A limiting hole 32 adapted to the threaded rod 29 is opened on the surface of the limiting plate 31. When the staff needs to clean the inside of the mixing cylinder 1, the cleaning plate 27 is aligned with the installation groove 26 and slid in, and the threaded rod 29 is aligned with the limiting hole 32. The rotating plate 30 is rotated to make the threaded rod 29 turn in to fix the cleaning plate 27. At this time, the rotating motor 6 is started again, and the mixing plate 7 drives the cleaning plate 27 to clean the dry powder remaining on the inner wall of the mixing cylinder 1, thus avoiding the need for the staff to clean manually and improving work efficiency.
[0031] Referring to Figure 7 as shown, in this embodiment: third sliding grooves 33 are opened at the front end and the rear end inside the installation groove 26. Third sliding blocks 34 are fixed to the front end and the rear end of the cleaning plate 27. The third sliding blocks 34 are slidably connected inside the third sliding grooves 33. Through the setting of the third sliding grooves 33 and the third sliding blocks 34, a stable guiding effect can be formed when the cleaning plate 27 is installed inside the installation groove 26, making the installation of the cleaning plate 27 more time-saving and labor-saving, and further improving the use experience.
[0032] Working principle: When the staff needs to adjust the flow rate of the blanking, press the pressing plate 17 inward to move the clamping block 20 out of the square groove 12, so that the limiting of the adjusting plate 10 is released. At this time, move the position of the adjusting plate 10 to move the current-limiting plate 14 to a position suitable for the dry powder blanking, and then release the pressing plate 17. At this time, the elastic spring 18 drives the pressing plate 17 to quickly pop into the square groove 12 to limit the adjusting plate 10, so as to achieve the rapid control of the flow rate during the dry powder blanking, effectively improve the flow rate control during various dry powder mixing, and improve the accuracy during the proportioning. Through the setting of the first chute 21 and the first slider 22, a stable limiting effect can be formed during the pressing or popping of the pressing plate 17, making the movement of the pressing plate 17 more stable, thereby improving the adjustment effect of the current-limiting plate 14. Through the setting of the second chute 23 and the second slider 24, the adjusting plate 10 can be limited when moving inside the fixing plate 9, preventing the adjusting plate 10 from being pulled off due to excessive pulling, which affects the current limiting of the dry powder. Through the setting of the return spring 25, when the current-limiting plate 14 is used up, the limiting of the adjusting plate 10 is released. At this time, the return spring 25 drives the adjusting plate 10 to quickly reset, so as to achieve the convenient reset after the use of the current-limiting plate 14, which is convenient for the staff to clean and use next time. Through the setting of the sealing plate 35, the dry powder will not leak during the blanking process, thus significantly improving the sealing performance during the blanking.
