The heating device adopts a structure in the prior art, such as a heating plate, and the specific structure is not repeated here. The vibrating screen 61 is connected with a vibrating motor, and the vibrating screen 61 is driven to continuously vibrate for screening when the vibrating motor is started.
The lower grinding disc 4 is located above the vibrating screen 61 in the vibrating screen assembly 6, the lower grinding disc 4 is in transmission connection with the driving mechanism 5, the lower grinding disc 4 is driven to rotate through the driving mechanism 5, specifically, the driving mechanism 5 comprises a driving motor 51 and a transmission rod 52, the driving motor 51 is located outside the box 61, an output shaft of the driving motor 51 is in transmission connection with one end of the transmission rod 52, the other end of the transmission rod 52 stretches into the box 61 to be fixedly connected with the lower grinding disc 4, and when the driving motor 51 is started, the transmission rod 52 is driven to rotate through the output shaft, so that the lower grinding disc 4 is driven to rotate.
The upper grinding piece 3 is arranged above the lower grinding disc 4, a grinding gap is formed between the lower surface of the upper grinding piece 3 and the upper surface of the lower grinding disc 4, and when the lower grinding disc 4 rotates, the upper grinding piece 3 and the lower grinding disc 4 are matched with each other to grind powder in the grinding gap. Specifically, the upper grinding member 3 includes an upper grinding disc 31 and a hollow connecting sleeve 32, the connecting sleeve 32 is fixedly connected to the middle part of the upper grinding disc 31, and through holes in the connecting sleeve 32 penetrate through the upper and lower surfaces of the upper grinding disc 31 and then are communicated with the grinding gap between the upper grinding member 3 and the lower grinding disc 4. In this embodiment, the upper grinding member 3 is communicated with the discharge port of the storage tank 1, and powder can flow out from the discharge port of the storage tank 1 and enter the grinding gap between the upper grinding member 3 and the lower grinding disc 4 through the through hole of the connecting sleeve 32. Specifically, the discharge gate department intercommunication of storage case 1 is provided with discharging pipe 2, and adapter sleeve 32 slidable suit is in the outside of discharging pipe 2, and is connected between adapter sleeve 32 and the storage case 1 to be equipped with lifter 8, lifter 8 is used for driving adapter sleeve 32 to reciprocate rectilinear motion along discharging pipe 2 axial to drive the grinding disc 31 and keep away from or be close to lower grinding disc 4. In this embodiment, the lifting member 8 is preferably a lifting air rod or an electric push rod, which has the advantages of flexible response, reliable structure and long service life.
In order to enable the powder to smoothly leave the lower grinding disc 4 and the upper grinding disc 31 and fall on the vibrating screen 61 after grinding, the embodiment designs the lower grinding disc 4 and the upper grinding disc 31 to be in conical disc structures with narrow upper part and wide lower part, so that when the powder enters a grinding gap, the powder gradually moves downwards under the action of gravity to the outer edge of the lower grinding disc 4 until the powder falls on the vibrating screen 61 after falling off the lower grinding disc 4. And the taper of the upper grinding disc 31 is smaller than that of the lower grinding disc 4 in this embodiment, with this structure, the included angle between the generatrix of the upper grinding disc 31 and the generatrix of the lower grinding disc 4 is larger than zero, i.e. the grinding gap formed between the lower grinding disc 4 and the upper grinding disc 31 gradually becomes smaller from inside to outside. The gap at one end close to the discharging pipe 2 is large, so that powder is easier to enter the grinding gap; the gap at one end far away from the discharging pipe 2 is small so as to grind powder more carefully and sufficiently. In addition, in this embodiment, the projection surface of the lower grinding pan 4 on the horizontal plane is positioned in the projection surface of the upper grinding pan 31 on the horizontal plane, and with this structure, when the powder moves to the outer edge of the lower grinding pan 4, the powder does not accumulate on the edge of the lower grinding pan 4, does not fly above the vibrating screen 61 due to centrifugal force, and falls into the vibrating screen 61 more quickly.
In order to avoid that the powder material which is formed into a block by the plate is stuck in the through hole of the connecting sleeve 32 due to the large volume, the powder material cannot smoothly enter the grinding gap.

In particular, in the present embodiment, three stirring rods 72 (see fig. 4) are provided, and the three stirring rods 72 are uniformly distributed along the circumferential direction of the mounting post 71. One end of the stirring rod 72 is fixedly connected to the mounting column 71, and the other end is inclined upward by 15-45 degrees. Compared with the stirring rod 72 which is horizontally arranged, the inclined structure of the embodiment is adopted, so that the stirring efficiency is higher, and the stirring effect is better.
In order to enhance the grinding effect of the lower grinding disc 4 and the upper grinding disc 31 on the powder, in this embodiment, a plurality of protrusions 311 with hemispherical sections are respectively protruded on two opposite sides of the lower grinding disc 4 and the upper grinding disc 31, the protrusions 311 are spirally distributed from top to bottom, and the protrusions 311 spirally distributed on the lower grinding disc 4 are staggered with the protrusions 311 spirally distributed on the upper grinding disc 31. The spiral distribution mode can drive the powder to move towards the outer edge of the grinding disc 4 during grinding, so that the powder is prevented from being accumulated in a grinding gap.
When in use, the discharge port of the storage box 1 is opened, so that powder can continuously enter the connecting sleeve 32 of the upper grinding disc 31 through the discharge pipe 2. Then, the driving motor 51 is started to drive the lower grinding disc 4 to rotate, and when the lower grinding disc 4 rotates, the stirring piece 7 rotates along with the lower grinding disc, so that the hardened powder in the connecting sleeve 32 is primarily scattered, and the powder smoothly enters the grinding gap. The powder entering the grinding gap is ground into fine powder particles in the process of rotating the lower grinding disc 4, gradually moves towards the edge of the lower grinding disc 4 under the action of centrifugal force and gravity until the powder falls off the lower grinding disc 4 and falls onto the vibrating screen 61, is subjected to vibrating screening through the vibrating screen 61, falls into the bottom of the box 62, and is dried by the heating device to prevent the powder from hardening again.
When the use is accomplished, in order to clear up the powder that remains on lower grinding plate 4 and the last grinding plate 31, can control lifting piece 8 start drive go up grinding plate 31 and keep away from lower grinding plate 4 along discharging pipe 2 axial movement, until possess sufficient space between lower grinding plate 4 and the last grinding plate 31 and conveniently clear up the operation, after the clearance is accomplished, control lifting piece 8 drive go up grinding plate 31 along discharging pipe 2 axial reverse movement reset can.
