[0033] Please see the appendix Figure 1 Appendix Figure 4 Appendix Figure 5 This utility model provides an embodiment of an inner-outer capsule raw material mixing and stirring device, comprising a hollow shell 1, a protective cover 3 fixedly connected to the top of the hollow shell 1, a motor 4 fixedly connected to the top of the inner wall of the protective cover 3, a rotating shaft 5 fixedly connected to the output end of the motor 4, a driving wheel 6 fixedly connected to the top of the outer wall of the rotating shaft 5, a driven wheel 7 meshing with the outer wall of the driving wheel 6, a rotating shaft 8 fixedly connected to the inner wall of the driven wheel 7, and a driven wheel 9 fixedly connected to the outer wall of the rotating shaft 8.

A feed valve 16 is connected to the inner wall of the feed pipe 15. An anti-blocking mechanism 2 is connected to the bottom of the hollow shell 1. The anti-blocking mechanism 2 is used to prevent the outlet from being blocked.

[0034] Specifically, feed valve 14 and feed valve 26 can quantitatively feed solid powder materials, making it convenient to mix materials. Rotary shaft 28 provides support for driven wheel 17 and driven wheel 29 and drives driven wheel 29 to rotate. The mesh holes of filter screen 2 12 can filter solid powder materials, and due to its inclined setting, it can play the role of stirring and breaking up lumpy materials when rotating.

[0035] Please see the appendix Figure 1 and attached Figure 3 The anti-blocking mechanism 2 includes a discharge pipe 201. The middle of the inner wall of the discharge pipe 201 is connected to the left side of the inner wall of the hollow shell 1. A discharge valve 202 is connected to the left side of the inner wall of the discharge pipe 201. A funnel 207 is connected to the right side of the inner wall of the discharge pipe 201. A filter screen 208 is fixedly connected to the inner wall of the funnel 207. A circulation pipe 203 is connected to the bottom of the inner wall of the hollow shell 1. A circulation valve 206 is connected to the middle of the inner wall of the circulation pipe 203. A water pump 204 is connected to the right side of the inner wall of the circulation pipe 203. A second circulation pipe 205 is connected to the output end of the water pump 204.

[0036] Specifically, the inlet of circulation pipe 203 is located at the lowest point of the hollow shell 1 to ensure that the sediment can be completely sucked up. When circulation valve 206 is open, water pump 204 will start to pump the material at the bottom through circulation pipe 203 to the top of the hollow shell 1, thereby realizing the re-stirring and mixing of the material. In addition, the discharge valve 202 is set to facilitate the control of the material discharge process and ensure smooth and accurate discharge.

[0037] Please see the appendix Figure 1 and attached Figure 2 Multiple brackets 26 are fixedly connected to the bottom edge of the outer wall of the hollow shell 1. A control box 25 is fixedly connected to the middle of the outer wall of the hollow shell 1. A feed pipe 3 20 is connected to the top left of the inner wall of the hollow shell 1. A feed valve 3 21 is connected to the middle of the inner wall of the feed pipe 3 20. A feed port 22 is connected to the top of the inner wall of the feed pipe 3 20. A top cover 23 is slidably connected to the top of the outer wall of the feed port 22. A feed port 17 is connected to the top of the inner wall of the feed pipe 13. A top cover 18 is slidably connected to the outer wall of the feed port 17.

[0038] Specifically, feed inlet 17 and feed inlet 22 are used for adding different raw materials, top cover 18 and top cover 23 can be used for dust prevention, control box 25 facilitates operator monitoring and adjustment of the mixing process, and bracket 26 is used to support the equipment, ensuring the stability and support of the entire equipment.

[0039] Please see the appendix Figure 2 and attached Figure 5 A sealing sleeve 19 is fixedly connected to the middle of the outer wall of the rotating shaft 1 5. Multiple stirring paddles 24 are fixedly connected to the bottom of the outer wall of the rotating shaft 1 5. The bottom of the inner wall of the feed pipe 2 15 is connected to the top right side of the inner wall of the hollow shell 1. The bottom end of the rotating shaft 2 8 is rotatably connected to the top right side of the outer wall of the hollow shell 1.

[0040] Specifically, the sealing sleeve 19 ensures the seal between the rotating shaft 5 and the hollow shell 1 when rotating, preventing raw material leakage during the stirring process. The stirring paddle 24 is evenly distributed at the bottom of the rotating shaft 5, and as the rotating shaft 5 rotates, it efficiently stirs and mixes the raw materials in the hollow shell 1.

[0041] Working principle: After the operator completes the material proportioning, the motor 4 is turned on first. Liquid material is added from feed inlet 22, and solid powder material is added from feed inlet 17. Feed valves 3 21, 14, and 2 16 are opened according to the material addition process. After the motor 4 is turned on, the drive wheel 6 will rotate. Through transmission, the driven wheel 3 10 and the mixing chamber 11 will rotate. When feed valve 1 14 is opened, the solid powder material enters the mixing chamber 11. Non-lumpy material is filtered out by filter screen 2 12 in the mixing chamber 11 and enters the hollow shell 1 for mixing. Since filter screen 2 12 is set at an angle in the mixing chamber 11, it can stir the material when it rotates, breaking up the lumpy material, so that it is not easy for lumps to form in the subsequent mixing in the hollow shell 1.

[0042] When the material is stirred in the hollow shell 1, high concentration sedimentation is likely to occur at the bottom. At this time, the discharge valve 202 is closed, and the material that does not meet the requirements is blocked by the filter screen 208. After opening the circulation valve 206, the water pump 204 is turned on to transport the bottom material through the pipeline to the top of the inner wall of the hollow shell 1 for stirring again, so as to prevent large pieces of material from appearing at the bottom and to prevent the discharge pipe 201 from being blocked.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
