Fix the filter plates inside the grinding bottom cylinder through the fixing assembly, and connect the guide hopper to the internal threaded cylinder by rotating it; S2, start the grinding motor, the grinding motor drives the grinding rod and the grinding roller to rotate, the particles roll between the grinding roller and the raised strips on the grinding cylinder, generating a sliding friction effect, and the ground particles fall into the processing cylinder through the filter plate and the guide hopper; S3. The electric heating plate inside the inner wall of the processing cylinder has a certain drying effect on the particles falling into the processing cylinder. The scattering motor drives the rotating rod to rotate, thereby driving the scattering rod to scatter the particles accumulated in the processing cylinder. The particles after grinding inside are scattered and dried by the processing cylinder to avoid agglomeration of the grinding particles. The particle raw materials passing through the processing cylinder finally fall from the discharge pipe. S4, separating the stirring barrel and the top cover, mixing the ground granular raw materials and putting them into the stirring barrel, and adding production raw materials such as starch aqueous solution into the stirring barrel.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention movably connects the filter plate and the grinding cylinder by installing a fixing assembly.

[0016] 2. The present invention is equipped with an electric telescopic push rod and a pressure plate.

[0017] 3. The present invention is equipped with a processing cylinder to break up and dry the ground raw materials. The breaking up motor drives the rotating rod to rotate. The breaking up rod rotates in the processing cylinder to break up the accumulated particles. At the same time, the electric heating plate inside the inner wall of the processing cylinder dries the particles being broken up in the processing cylinder to avoid breaking up and drying the ground particles, avoid agglomeration of the ground granular raw materials, and ensure the use effect of the ground granular raw materials.

[0018] 4. The present invention is equipped with a driving motor, a cam and a telescopic spring. During the process of drying the spun fibers, the driving motor drives the rotating shaft and the cam to rotate together.

[0038] Working principle: according to the production requirements, appropriate production raw materials are weighed, and according to the specific raw material particle size requirements, the filter plate 14 with the appropriate mesh size is fixed to the inside of the grinding bottom cylinder 3 through the fixing assembly, and the guide hopper 21 is connected to the internal threaded cylinder 20 by rotating it, and the grinding motor 7 is started, and the grinding motor 7 drives the grinding rod 8 and the grinding roller 9 to rotate, so as to grind the particles in the grinding cylinder 4; During the grinding process, the electric telescopic push rod 17 drives the pressing plate 18 to move downward, and the pressing plate 18 presses downward the raw materials to be ground accumulated on the top of the grinding roller 9, so that the raw materials to be ground can fall into the grinding roller 9 and the raised strips on the inner wall of the grinding cylinder 4 more quickly for grinding, thereby improving the grinding rate. The ground particles pass through the filter plate 14 and the guide hopper 21 and fall into the processing cylinder 22. The processing cylinder 22 breaks up and dries the ground particles to avoid agglomeration of the ground particles. The particle raw materials passing through the processing cylinder 22 finally fall from the discharge pipe 27. The stirring barrel 5 and the top cover 28 are separated, the ground granular raw materials are mixed and put into the stirring barrel 5, and the production raw materials such as starch aqueous solution are added into the stirring barrel 5. After the raw materials are put in, the stirring motor 29 is started, and the stirring motor 29 drives the stirring rod 35 to rotate, and the mixed raw materials in the stirring barrel 5 are stirred until the mixed raw materials form a uniform mixed solution. After the mixing is completed, the discharge pipe 36 is opened by the control valve 37 to discharge the mixed solution from the discharge pipe 36, and the mixed solution is poured into the electrostatic spinning machine, and the ceramic raw material mixed solution is spun to obtain spun fibers; Open the door 38 of the drying box 6, place the spun fibers in the storage frame 46, and the fan 42 on the partition 41 blows the heat emitted by the electric heating network 43 to the surface of the spun fibers in the storage frame 46. The driving motor 47 drives the rotating shaft 48 and the cam 49 to rotate together. The irregular circular motion of the cam 49 applies pressure to the storage frame 46, so that the storage frame 46 swings up and down under the support of the telescopic spring 45. The water contained in the spun fibers in the storage frame 46 is separated from the spun fibers more quickly under the action of inertia, so that the moisture in the spun fibers drips through the storage frame 46 into the interior of the drying box 6 and is discharged from the drain pipe 50, thereby achieving the purpose of drying the spun fibers.
