Description

Technical Field

[0001] This utility model relates to the field of pregelatinized starch production technology, specifically a mixing device. Background Technology

[0002] Pregelatinized starch is a modified starch obtained by partially or completely breaking down starch granules through chemical or mechanical methods. It is commonly used in tablets as a binder, diluent, and disintegrant, and has a self-lubricating effect. Pregelatinized starch has stronger water absorption and smaller granules. During the production and processing of pregelatinized starch, chemical agents need to be added, and the starch and chemical agents are reacted through a mixing device to produce pregelatinized starch.

[0003] Utility model patent application publication number 20231437241.3 discloses a mixing device for producing starch, belonging to the technical field of starch mixing.

This device incorporates a stirring step before mixing, improving the quality of the mixed starch, resulting in more uniform mixing and strong practicality.

[0004] According to the above device, there is a mixing device, but it still has shortcomings in actual use. The most obvious one is that when mixing starch, a single roller is usually used for mixing, which is not convenient to mix the powder thoroughly. In addition, the powder that is contacted by the mixing roller is usually in a relatively restricted state, which affects the starch mixing effect. Therefore, this utility model provides a mixing device to solve the above problems. Summary of the Invention

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.

[0019] Example 1: Please see Figure 1-4 A mixing device, comprising: Support 1, bearing box 2 is fixedly connected to the top of support 1, support shaft 3 is rotatably connected to the top of bearing box 2, and material tank 4 is fixedly connected to the top of support shaft 3; The upright plate 5 is fixedly connected to one end of the top of the support 1.

[0020] Please see Figure 3 and Figure 4 In this embodiment, the mixing component 8 includes: The sealing cover 10 is fixedly connected between the bottoms of the two extension frames 7. The center shaft 11 is vertically rotatably connected to the middle of the sealing cover 10, and the bottom end of the center shaft 11 is fixedly connected to the mounting plate 12. Multiple mixing shafts 13 are vertically rotatably connected to the mounting plate 12. Each mixing shaft 13 has a linkage spur gear 14 fixedly connected to its top end.

Please see Figure 2 In this embodiment, the bottom end of the sealing cap 10 is provided with an assembly hole, and the top end of the outer side of the material tank 4 is also rotatably connected to the inside of the assembly hole. More specifically, by setting the assembly hole, when the sealing cover 10 is fixed, the top of the material tank 4 can be supported by the sealing cover 10 to prevent the top of the material tank 4 from shaking uncontrollably when it rotates. In addition, the presence of the sealing cover 10 can also seal the top of the material tank 4 to prevent the powder and the agent from being directly exposed to the environment during the mixing process. Secondly, the presence of the sealing cover 10 can also prevent dust and debris from entering the material tank 4. At the same time, the dust during mixing is also restricted by the sealing cover 10 and will not be scattered, so it will not cause pollution to the environment. Furthermore, the sealing cap 10 helps to control the humidity inside the material tank 4, ensuring the moisture content and component stability of the starch. Please see Figure 2 In this embodiment, a feeding pipe is fixedly connected to the top of the sealing cap 10. Through the setting of the feeding pipe, the powder and medicine can be fed from the top of the sealing cap 10 into the material tank 4. In order to prevent dust and debris from entering the material tank 4 through the feeding pipe, a sealing cover can also be provided on the feeding pipe in this embodiment; Please see Figure 2 In this embodiment, a discharge pipe is also provided at the bottom of the outer side of the material tank 4, and a manual valve is provided on the discharge pipe. Through the setting of the discharge pipe, the starch inside the material tank 4 can be conveniently drawn out of the material tank 4. Please see Figure 3 In this embodiment, a stirring disc is fixedly connected to the outside of each mixing shaft 13, and there are no less than three stirring discs on each mixing shaft 13; More specifically, by setting up the mixing disc, when the mixing shaft 13 rotates, the mixing disc can come into contact with the powder and agents inside the material tank 4 over a larger range, reducing the blind spot of the mixing shaft 13. Furthermore, each mixing disc is equipped with no fewer than three mixing fan blades, and the mixing fan blades are set at an angle; Example 2: Please see Figure 2 This embodiment provides a technical solution based on Embodiment 1: the transmission assembly 9 includes: The reducer 17 is fixedly connected to the top of the horizontal plate 6, and the power output end of the reducer 17 is also fixedly connected to the central shaft 11. The top of the reducer 17 is fixedly connected to the transmission motor 18, and the output end of the transmission motor 18 is fixedly connected to the power input end of the reducer 17. Linkage shaft 19 is rotatably connected between the horizontal plate 6 and the support 1. The top of the outer side of the linkage shaft 19 and the outer side of the central shaft 11 are both fixedly connected to the transmission sprocket 20, and the two transmission sprockets 20 are connected by a chain. The reversing spur gear 21 is fixedly connected to one end of the linkage shaft 19 located inside the bearing box 2. The support shaft 3 is fixedly connected to one end of the bearing box 2 with a reduction spur gear 22, and the reduction spur gear 22 meshes with the reversing spur gear 21. Please see Figure 2 In this embodiment, a stabilizing seat is fixedly connected to the side of the upright plate 5 near the linkage shaft 19. Stabilizing holes are provided at the top and bottom of the stabilizing seat, and the middle part of the linkage shaft 19 is connected to the inside of the stabilizing hole through a ball bearing. More specifically, by setting up the stabilizing seat, the middle part of the linkage shaft 19 can be supported when the linkage shaft 19 is set with a large span, so as to ensure the stability of the linkage shaft 19 rotating between the support 1 and the horizontal plate 6. Furthermore, the use of ball bearings reduces the friction of the linkage shaft 19 rotating inside the stabilizing hole, allowing the linkage shaft 19 to transmit power more smoothly. Please see Figure 2 In this embodiment, the diameter of the reversing spur gear 21 is smaller than the diameter of the reduction spur gear 22; More specifically, by changing the diameter of the reversing spur gear 21 and the reduction spur gear 22, the rotation speed of the support shaft 3 can be effectively reduced to ensure the stability of the material tank 4 application.

[0021] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0022] Working principle: First, the starch powder and chemical agents are poured into the loading tank 4. Then, the drive motor 18 is started, and the power of the drive motor 18 is transmitted to the central shaft 11 through the reducer 17. The mixing shaft 13 is driven to rotate along the support ring 15 by the mounting plate 12. In conjunction with the connection between the mixing shaft 13 and the linkage spur gear 14, the linkage spur gear 14 will move at the drive spur gear 16 during the rotation of the mixing shaft 13, thereby enabling the mixing shaft 13 to rotate. This stirs the powder and chemical agents inside the loading tank 4, allowing the chemical agents and powder to react fully. With the help of the chain, the power of the central shaft 11 can be transmitted to the linkage shaft 19. With the connection between the linkage shaft 19 and the reversing spur gear 21, the reversing spur gear 21 can follow the rotation of the linkage shaft 19 and drive the reduction spur gear 22. In turn, the material tank 4 is driven to rotate by the support shaft 3, thereby forming a multi-mixing of chemical agents and powders with the mixing shaft 13.
