The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of this utility model, and should not be construed as limiting the utility model.

Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0033] In one embodiment of this utility model, such as Figures 1-4 As shown, a multi-stage mixer for material mixing and processing includes a drive mechanism 1 and a mixing mechanism 2. The mixing mechanism 2 is disposed on the drive mechanism 1, and the drive mechanism 1 drives the mixing mechanism 2 to rotate.

[0034] The drive mechanism 1 includes a drive motor 11 and a drive shaft 12. The drive shaft 12 is mounted on the drive motor 11, and the stirring mechanism 2 is mounted on the drive shaft 12. The drive motor 11 drives the drive shaft 12 and the stirring mechanism 2 to rotate.

[0035] The mixing mechanism 2 includes a mixing shaft 21, a primary mixing blade 22, a secondary mixing blade 23, and a tertiary mixing blade 24. One end of the mixing shaft 21 is connected to the drive shaft 12. The primary mixing blade 22, secondary mixing blade 23, and tertiary mixing blade 24 are sequentially arranged on the mixing shaft 21. A first heating pipe 211 is installed at the bottom of the mixing shaft 21 and is located inside the mixing shaft 21. A second heating pipe 233 is installed inside the secondary mixing blade 23. The first heating pipe 211, located at the bottom of the mixing shaft 21 and inside the shaft, can directly heat the material in the lower layer of the mixing tank. The lower layer of material is prone to sedimentation due to gravity, especially plastic materials, which are highly viscous at low temperatures and easily clump together. Heating reduces the viscosity of the material, reduces sedimentation and clumping, and makes the lower layer of material easier to be lifted and dispersed by the tertiary mixing blade 24, participating in the overall material circulation and avoiding the problem of insufficient mixing due to long-term retention of the lower layer of material. The second heating element 233 is located inside the secondary agitator 23 and can precisely heat the material in the middle layer of the mixing tank. Heating can improve the fluidity of the material in the middle layer, allowing the material pushed by the primary agitator 22 and the material lifted by the tertiary agitator 24 to penetrate and mix more easily in the middle layer, further improving the uniformity of mixing.

[0036] The multi-stage mixer for material mixing provided in this application covers materials at different depths in the mixing tank through the layered arrangement of primary mixing blade 22, secondary mixing blade 23 and tertiary mixing blade 24 (distributed at intervals along the mixing main shaft 21), thereby increasing the radial mixing range and making the material mixing more thorough.

[0037] In another embodiment of this utility model, two primary stirring paddles 22 are provided and arranged in parallel and symmetrically. Each primary stirring paddle 22 includes a primary stirring rod 221 and primary stirring teeth 222. One end of the primary stirring rod 221 is fixedly connected to the stirring main shaft 21. Multiple primary stirring teeth 222 are provided and uniformly fixedly connected to the bottom side of the primary stirring rod 221, with adjacent primary stirring teeth 222 spaced apart. When the multiple primary stirring teeth 222 uniformly spaced on the bottom side of the primary stirring rod 221 rotate, the primary stirring teeth 222 can "cut" the aggregated materials (such as plastic granules and powders), breaking up the material agglomerates and allowing the cut materials to diffuse in all directions under the action of stirring force, thereby improving the overall mixing efficiency.

[0038] In another embodiment of this utility model, two secondary stirring paddles 23 are provided and arranged in parallel and symmetrically. Each secondary stirring paddle 23 includes a secondary stirring rod 231 and secondary stirring teeth 232. One end of the secondary stirring rod 231 is fixedly connected to the stirring main shaft 21. A second heating tube 233 is fixedly connected inside the secondary stirring rod 231. Multiple secondary stirring teeth 232 are provided and uniformly fixedly connected to the bottom side of the secondary stirring rod 231, with adjacent secondary stirring teeth 232 spaced apart. When rotating, the multiple secondary stirring teeth 232, evenly spaced on the bottom side of the secondary stirring rod 231, can "cut" aggregated materials (such as plastic granules or powder), breaking up material agglomerates and allowing the cut materials to diffuse outwards under the stirring force, thus improving overall mixing efficiency.

[0039] In another embodiment of this utility model, two three-stage stirring paddles 24 are provided, arranged in parallel and symmetrically. Each three-stage stirring paddle 24 includes a three-stage stirring rod 241 and three-stage stirring teeth 242. One end of the three-stage stirring rod 241 is fixedly connected to the stirring shaft 21. Multiple three-stage stirring teeth 242 are provided and uniformly fixedly connected to the bottom side of the three-stage stirring rod 241, with adjacent teeth spaced apart. When rotating, the multiple uniformly spaced teeth 242 on the bottom side of the three-stage stirring rod 241 can "cut" aggregated materials (such as plastic granules or powder), breaking up material agglomerates and allowing the cut materials to diffuse outwards under the stirring force, thus improving overall mixing efficiency.

[0040] The multi-stage mixer for material mixing provided in this application covers materials at different depths in the mixing tank through the layered arrangement of primary mixing blade 22, secondary mixing blade 23 and tertiary mixing blade 24 (distributed at intervals along the mixing main shaft 21), thereby increasing the radial mixing range and making the material mixing more thorough.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
