sequence of mechanical actions of the whole device:

when the working is started, the motor 29 is started, the ceramic to be processed is added from the top conical cavity 38, the motor 29 drives the left driving belt wheel 30 to rotate through the motor shaft 15, the left driving belt wheel 30 drives the upper driven belt wheel 33 to rotate through the belt 31, the upper driven belt wheel 33 drives the lower driving conical tooth 48 to rotate through the driving conical tooth shaft 49, the lower driving conical tooth 48 drives the conical tooth shaft 46 to rotate through the lower side conical tooth 47, the conical tooth shaft 46 drives the rotating conical tooth 50 to rotate around the conical tooth shaft 46 through the rotating shaft 51, because the rotating conical tooth 50 is meshed with the inverted conical tooth 45, the inverted conical tooth 45 and the conical tooth shaft 46 rotate under the interaction of the rotating conical tooth 50 and the inverted conical tooth 45, the rotating conical tooth 50 rotates around the rotating shaft 51 while rotating around the conical tooth shaft 46, the rotating conical tooth 50 drives the rotating stub shaft 52 to rotate around the rotating shaft 51 while rotating around the rotating shaft 51, the rotating short shaft 52 can reciprocate up and down relative to the rotating shaft 51, because the rotating short shaft 52 is connected with the annular cavity 44 in a sliding fit manner, the rotating short shaft 52 can drive the sliding sleeve 36 to reciprocate up and down through the annular cavity 44, meanwhile, because the inverted cone teeth 45 rotate reversely, the inverted cone teeth 45 drive the upper grinding disc 43 and the cone-shaped block 40 to rotate through the top shaft 39, because the upper grinding disc 43 is abutted against the top cone-shaped cavity 38, the friction force between the upper grinding disc 43 and the top cone-shaped cavity 38, the upper grinding disc 43 can drive the side grinding wheel 58 to rotate by taking the side grinding wheel shaft 57 as the center, and because of the existence of the slider spring 55, when the sliding sleeve 36 reciprocates up and down, the slider spring 55 can provide the downward pressure to the side grinding wheel shaft 57 through the slider 53, so that the side grinding wheel 58 is always engaged with the upper;

due to the reciprocating motion of the sliding sleeve 36 and the rotation of the conical block 40, the lower end surface of the conical block 40 is matched with the top conical cavity 38 to extrude and grind the ceramic entering the top conical cavity 38, and the ceramic is preliminarily processed into powder;

when the ceramic powder is processed to enter the grinding cavity 59 through the top conical cavity 38 and fall into the upper end face of the upper grinding disc 43, the upper grinding disc 43 rotates to drive the ceramic powder to be in contact with the side grinding wheel 58, the upper grinding disc 43 is in contact with the side grinding wheel 58 to grind and process the ceramic powder again, and due to the sliding characteristic among the ceramic powder, the ceramic powder slides along the upper end face of the upper grinding disc 43 and falls into the semicircular arc cavity 13 after being ground to a target state;

at the same time, the motor shaft 15 will drive the fan blades 14 to rotate, and the fan blades 14 generate air flow to blow the powder entering the semi-circular arc cavity 13 into the end wall of the semi-circular arc cavity 13

In the upper belt wheel cavity 12, if the quality state of the ceramic powder does not meet the requirement, the ceramic powder is accumulated on the lower end wall of the semicircular arc cavity 13 under the self gravity and enters the inclined block cavity 67, when unqualified powder in the inclined block cavity 67 is accumulated to a certain degree, the inclined block 61 overcomes the elasticity of the inclined block spring 62 to move downwards under the action of the powder gravity, and when the lower end face of the inclined block 61 is contacted with the pressure switch 66, the pressure switch 66 triggers the electromagnet 20 to start;

the electromagnet 20 generates suction to attract the coupler 22 to move leftwards against the pulling force of the coupler spring 23 and to be in spline fit with the gear shaft 19, the coupler 22 connects the gear shaft 19 with the coupler shaft 24, the right driving pulley 28 drives the lower driven pulley 26 to rotate through the lower belt 27, the lower driven pulley 26 drives the coupler 22 to rotate through the coupler shaft 24, the coupler 22 drives the gear 65 to rotate through the gear shaft 19, the gear 65 drives the rack 64 to move upwards, the bevel gear shaft 46 drives the bevel block 61 to move upwards, the bevel block 61 drives the storage block 60 to move upwards through the bevel block spring 62, when the storage block 60 moves to the lower side of the middle cavity 41, as the diameter of the middle cavity 41 just can only pass through the bevel block 61, the storage block 60 is abutted against the upper end wall of the semicircular arc cavity 13, the bevel block 61 pushes the unqualified powder above to continue to move upwards along the middle cavity 41 until leaving the middle cavity 41, at this time, the powder can enter the top conical cavity, meanwhile, the electromagnet 20 is closed, the coupler 22 is pulled by the coupler spring 23 to move rightwards, the gear shaft 19 is separated from the coupler 22, and the inclined block 61 and the storage block 60 are descended and reset;

acceptable powder will travel upward through the left side chamber 42 and be collected.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention.
