[0052] Preferably, the first connecting disk 2242 and the second connecting disk 2243 are connected by magnetic attraction based on the magnetic attraction connection method, so that the connection is more convenient, and when the driving member 221 and the stirring device 3 are driven to rise and fall by the lifting device 6 at the same time, the connection between the first connecting disk 2242 and the second connecting disk 2243 can be disconnected when there is no need to drive the adjusting disk 222 to move, so as to avoid affecting the stirring process; at this time, preferably, the limiting cylinder 2245 moves with the lifting device 6, and when the second connecting disk 2243 enters into the limiting cylinder 2245, it completes the docking with the first connecting disk 2242.

[0053] In some preferred embodiments, Figure 5 As shown, it also includes a limiting cylinder 2245; the limiting cylinder 2245 is sleeved on the outside of the first connecting disk 2242 and the second connecting disk 2243, and is gap-matched with the first connecting disk 2242 and the second connecting disk 2243 to guide and limit the moving direction of the first connecting disk 2242 and the second connecting disk 2243; based on the limitation of the limiting cylinder 2245, the moving direction of the connecting member 224 is limited along the axial direction of the first hopper 223, thereby ensuring the consistency of the moving direction of the adjustment disk 222, thereby ensuring the effect of promoting discharge.

[0054] Preferably, the limiting cylinder 2245 is provided with an observation window 22451, and a marking structure 22452 is provided adjacent to the limiting cylinder 2245 and the observation window 22451; the marking structure 22452 is used to indicate the position of the first connecting disk 2242 or the second connecting disk 2243, and the limiting cylinder 2245 can be installed on the cylinder body 1 or connected to the driving member 221; by observing the position of the first connecting disk 2242 or the second connecting disk 2243, the position of the adjustment disk 222 can be judged, thereby, the blocking ratio of the feed port of the first hopper 223 by the adjustment disk 222 can be determined, and the feeding speed can be determined.

[0055] Specifically, marking structure 22452 is a tick mark.

[0056] In some preferred embodiments, Figure 3 and 7 As shown, the stirring device 3 includes a stirring motor 31 and a stirring paddle 32; the stirring motor 31 is used to drive the stirring paddle 32 to rotate; the stirring paddle 32 is used to stir and mix the materials output from the feed port 11; preferably, the stirring paddle 32 has multiple blades, and is arranged perpendicular to the stirring shaft.

[0057] Preferably, the discharge port of the first hopper 223 is located above the rotation range of the stirring paddle 32 and close to the outer periphery of the rotation range; based on this, the materials are stirred and mixed more fully.

[0058] Preferably, the receiving plate 4 is arranged perpendicular to the rotation axis of the stirring paddle 32 .

When the receiving plate 4 rises to form a receiving surface with the annular seat 7, there is no interaction between it and the grinding plate 5, and only stirring and mixing of materials are performed. When the receiving plate 4 descends and forms a material channel with the inner wall of the cylinder 1, the material falls onto the grinding plate 5 under the centrifugal force of the rotation of the receiving plate 4. At this time, the receiving plate 4 and the grinding plate 5 can cooperate in grinding and mixing, or the receiving plate 4 continues to descend and cooperates with the grinding plate 5 to grind and mix the material, and then discharge it through the discharge hole 51.

[0062] Preferably, the lifting device 6 is also used to drive the driving member 221 to move up and down. For example, the driving member 221 and the stirring motor 31 are connected to the lifting device 6 through the mounting plate 102 to facilitate the installation and adjustment of the second connecting plate 2243.

[0063] Preferably, the lifting device 6 detects the lifting height through a height detection element (not shown) so that the lifting and lowering stops when the receiving plate 4 reaches the position of the annular seat 7; specifically, the height detection element can be a laser rangefinder or a sliding resistor combined with a resistance measuring instrument. For example, the sliding piece of the sliding resistor connected to the driving end of the lifting device 6 moves, and then the resistance is measured by the resistance measuring instrument, and the resistance value when the receiving plate 4 reaches the position of the annular seat 7 is recorded, and this value is used as a standard for judging whether the receiving plate 4 has reached the position of the annular seat 7.

[0064] In some preferred embodiments, as shown in the figure, the lifting device 6 includes a lifting component 61 and a guide component 62; the lifting direction of the lifting component 61 is the same as the guiding direction of the guide component 62, and the lifting component 61 and the guide component 62 are fixed at one end and connected to the stirring device 3 at the other end.

[0065] Optionally, the lifting assembly 61 is a linear drive mechanism, such as a cylinder or a motor in conjunction with a lead screw or a gear rack, or other drive mechanisms capable of achieving linear movement.

[0066] Optionally, the guide assembly 62 includes a guide tube 621 and a guide rod 622 .

[0067] In some preferred embodiments, Figure 2 As shown, a controller 9 is also included. The controller 9 is electrically connected to the stirring device 3 and the feeding device 2 to control the stirring device 3 and the feeding device 2 to work or not.

[0068] In some preferred embodiments, Figure 2 As shown, it also includes a base 101, and the cylinder body 1 is installed on the base 101.

[0069] The working process of the mixing device is described below:

[0070] When the device is in use, the lifting device 6 is started to drive the driving member 221, the first connecting plate 2242 and the limiting cylinder 2245 downward, and the second connecting plate 2243 enters the interior of the limiting cylinder 2245, and the first connecting plate 2242 moves until it is magnetically connected to the second connecting plate 2243. When the receiving plate 4 enters the position of the annular seat 7, the lifting device 6 is started to stop moving, and the required material is added to the feeding hopper 211, and the feeding auger 213 is started to rotate and feed. The feeding auger 213 pushes the material into the first hopper 223. After entering the first hopper 223, the driving member 221 can drive the adjusting plate 222 to move to block the discharge port of the feeding pipe 212 to adjust the feeding speed (specifically, the driving member 221 drives and then drives the adjusting plate 222 to move through the second connecting plate 2243 to block the discharge port of the feeding pipe 212). After the material enters the first hopper 223, it falls downward, and then moves to When the material falls, the stirring motor 31 is started, and the stirring motor 31 drives the stirring paddle 32 to rotate, and the falling material is initially stirred, and the material is gradually accumulated on the receiving plate 4; when the feeding is completed, the driving member 221 drives the adjusting plate 222 to move up and down quickly, and the movement generates airflow inside the first hopper 223, and the airflow pushes the residual material inside the first hopper 223 outward. After stirring for a period of time (which can be determined according to the working conditions) and mixing evenly, the lifting device 6 drives the receiving plate 4 to move to a position lower than the annular seat 7. Under the action of the centrifugal force generated by the rotation of the receiving plate 4, the material passes through the annular groove 13 and falls onto the grinding plate 5, and then the receiving plate 4 and the grinding plate 5 cooperate to grind. During the grinding process, the material continues to enter from the side, enters the grinding port through the extrusion grinding between the materials, and falls to the discharge port 12 through the discharge hole 51 on the grinding plate 5, and the discharge device 8 is started to discharge the internal material outward. The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation modes, which are merely illustrative rather than restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are within the protection of the present invention.
