[0026] The following is combined with Figure 1-2 This application is described in further detail.

[0027] A mixing paddle, such as Figure 1 As shown, it includes a shaft body 1 and stirring blades 2. The interior of the shaft body 1 is hollow, which effectively reduces the overall weight. The stirring blades 2 are arranged at intervals along the axial direction of the shaft body 1, and each stirring blade 2 is at a different angle in the circumferential direction of the shaft body 1, that is, each stirring blade 2 is in a different area on the axial projection. In addition, the inclination angle of each stirring blade 2 is also different, so that the mixing effect produced by each stirring blade 2 during the rotation process is different, achieving a better mixing effect, and better ensuring the uniformity and sufficiency of the material stirring and mixing. In addition, the stirring blade 2 rotates to drive the material forward more slowly, and the material can be stirred and mixed in the mixer for a longer time.

[0028] like Figure 1 As shown, the stirring blade 2 includes a mounting portion 3 and a blade portion 4, and the inclination direction of each blade portion 4 is different. At the same time, a mounting strip 5 is fixedly provided on the shaft body 1, and the mounting strip 5 is arranged one-to-one corresponding to each stirring blade 2. The mounting portion 3 and the mounting strip 5 are detachably connected, and mounting holes 6 are provided on the mounting portion 3 and the mounting strip 5. The mounting portion 3 is fixed to the mounting strip 5 by inserting screws into the mounting holes 6, so that the stirring blade 2 can be independently detachable. In actual use, it can be repaired or replaced separately to reduce unnecessary waste. In this embodiment, the mounting strip 5 is in the shape of an arc strip, and multiple mounting holes 6 are evenly distributed around the circumference to improve the stability of the connection and installation; in addition, adjacent stirring blades 2 are installed and fixed on different sides of the corresponding mounting strips 5, which can effectively reduce the risk of interference and collision between adjacent stirring blades 2.

[0029] like Figure 1As shown, a reinforcement block 7 connecting the mounting portion 3 and the blade portion 4 is provided at the connection between the two. The reinforcement block 7 is fixed to the mounting portion 3 and the blade portion 4, which effectively improves the structural strength of the connection and avoids the phenomenon of easy breakage at the connection between the blade portion 4 and the mounting portion 3. The width of the mounting portion 3 gradually decreases from one end close to the shaft body 1 to the other end, so that the width of the end where the mounting portion 3 is connected to the shaft body 1 is larger and then gradually decreases. The mounting portion 3 is tapered as a whole, which ensures the structural strength of the connection while reducing the contact area between the mounting portion 3 and the material, thereby reducing the axial resistance when the mixing blade 2 rotates, achieving a certain energy-saving purpose.

[0030] Example 2

[0031] A mixing mechanism, such as Figure 2 As shown, it includes a shell 8 and embodiment 1. The interior of the shell 8 is hollow to form a mixing chamber. The mixing paddle is located in the mixing chamber. Both ends of the mixing paddle are rotatably connected to the shell 8. A feed port 9 is provided at the top of one end of the shell 8, and a discharge port 10 is provided at the bottom of the other end. The material enters from the feed port 9 and is then mixed under the rotation and stirring of the mixing paddle. At the same time, the rotation of the mixing paddle continuously transports the material toward the discharge port 10, and finally discharged from the discharge port 10.

[0032] like Figure 2 As shown, a vertical baffle plate 11 is provided on the side of the bottom inner wall of the shell 8 corresponding to the discharge port 10, and the baffle plate 11 is located on the side of the discharge port 10 close to the feed port 9. The baffle plate 11 is used to partially block the material. A discharge port 12 is also provided at the bottom of the shell 8, and the discharge port 12 is located on the side of the baffle plate 11 facing away from the discharge port 10. The diameter of the discharge port 12 is much smaller than the diameter of the discharge port 10, so that only part of the material is discharged from the discharge port 12 in actual use. As the material in the shell 8 becomes more and more, when the accumulated height of the material exceeds the baffle plate 11, the material is finally discharged from the discharge port 10 through the baffle plate 11, so that the material is stirred and mixed in the shell 8 for a longer time, thereby achieving a better mixing effect. After the mixing is completed, the material in the shell 8 can be completely discharged through the discharge port 12 to avoid material residue.

[0033] like Figure 2 As shown, a discharge connector 13 is provided at the corresponding discharge position at the bottom of the shell 8, and the discharge port 10 and the discharge port 12 are both located in the discharge connector 13, so that the discharge structure is integrated. It is only necessary to connect the discharge connector 13 to the external material receiving mechanism to realize the unified discharge of the shell 8.

[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
