[0002] In production, it is often necessary to evenly mix multiple powdered raw materials, which requires the use of a mixing device. Currently, the most common mixing device is a V-shaped mixer. When the V-shaped barrel rotates, the raw materials move up and down and left and right inside the V-shaped barrel under the action of gravity to mix. This achieves good mixing uniformity. However, since it mainly relies on gravity for mixing, the movement speed of the raw materials caused by gravity is slow, resulting in slow mixing speed and long mixing time. Utility Model Content

[0015] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.
[0016] Specific implementation method: Figure 1-3As shown, a mixing device comprises a base 1, both sides of which are provided with pillars 11, and a cylindrical mixing barrel 3, both ends of which are closed, a feeding port is provided on the mixing barrel 3, and a cover is detachably connected to the feeding port, and the feeding port is preferably provided on the outer circumference of the mixing barrel 3, and the mixing barrel 3 is rotatably connected to a stirring shaft 31 coaxial therewith, the stirring shaft 31 passes through the mixing barrel 3 and its two ends are located outside the mixing barrel 3, a rotating sealing ring is provided between the stirring shaft 31 and the mixing barrel 3 to prevent leakage, and the two ends of the stirring shaft 31 are rotatably connected to the two pillars 11 respectively, and a stirring shaft 31 is provided on the stirring shaft There is a first blade 312, which is located in the mixing barrel 3. One end of the mixing barrel 3 is provided with an inner gear ring 32 coaxial therewith. A third gear 311 is provided on the stirring shaft 31. One of the pillars 11 is rotatably connected to the first gear 111, and the first gear 111 is meshed with both the inner gear ring 32 and the third gear 311. A motor 2 is provided on one of the pillars 11, and a second gear 21 is provided on the rotating shaft of the motor 2. The second gear 21 is meshed with either the inner gear ring 32 or the third gear 311. That is, the second gear 21 can mesh only with the inner gear ring 32 or only with the third gear 311. The rotation of the motor 2 can drive the stirring shaft 31 and the mixing barrel 3 to rotate in opposite directions, and the rotation speed of the stirring shaft 31 is greater than the rotation speed of the mixing barrel 3. The fast rotation of the first blade 312 increases the mixing speed and shortens the mixing time. The length of the first blade 312 should be significantly smaller than the radius of the mixing barrel 3. The amount of raw materials in the mixing barrel 3 should be limited, and the top surface of the raw materials should be lower than the stirring shaft 31. Furthermore, as the materials brought to the upper portion of the mixing barrel 3 fall under the action of gravity (the rotation speed of the mixing barrel 3 should be appropriate so that the raw materials are lifted and then fall from the upper portion), a portion of the materials will be pushed away by the faster-rotating first blade 312, changing the landing point and promoting mixing of the raw materials.
[0017] Preferably, the second gear 21 is meshed with the inner gear ring 32 . In this case, the top of the pillar 11 can be set lower than the top of the inner gear ring 32 , and the motor 2 can be set on the top of the pillar 11 , which is more convenient.
[0018] The plurality of first blades 312 are spaced apart in the axial direction of the stirring shaft 31 to form a first blade group. The plurality of first blade groups are symmetrically distributed about the axis of the stirring shaft 31 .
[0019] The stirring shaft 31 is also provided with a plurality of second blades 313. The plurality of second blades 313 are spaced apart in the axial direction of the stirring shaft 31 to form a second blade group. In the axial direction of the stirring shaft 31, the second blades 313 of the second blade group are respectively located between two adjacent first blades 312 of the first blade group. The plurality of second blade groups are symmetrically distributed about the axis of the stirring shaft 31, and the second blade groups are spaced apart from the first blade groups in the circumferential direction of the stirring shaft 31. The second blades 313 promote mixing of the raw materials.
[0020] The side of the first blade 312 and the second blade 313 facing the rotation direction is an arc surface, and the axis of the arc surface is located on the side of the arc surface facing away from the rotation direction. After being pushed away by the first blade 312 and the second blade 313, the raw materials diverge to both sides. After being pushed away by a single first blade 312 or the second blade 313, the raw materials move in a direction perpendicular to the axis of the stirring shaft 31 and in the axial direction of the stirring shaft 31, thereby promoting the mixing of the raw materials.
[0021] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention. In addition, the appended claims of the present invention are intended to cover all variations and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents thereof.
