The working principle is as follows: when particulate matter raw materials are poured into the feeding hole 101, the whole device starts to work, firstly, the particulate matter raw materials enter the particle screening mechanism 5 through the raw material box 102 and the raw material buffer box 103, along with the falling of the particulate matter raw materials to the filter screen II 501, the powder raw materials are filtered by the filter screen II 501 and fall to the radian powder pipe 104, then the lower air cylinder 108 drives the die seat 107 to move upwards, so that the concave rail 601 and the convex semicircle II 604 collide with each other, further frequent oscillation force is generated, the powder attached to the inner walls of the radian powder pipe 104 and the raw material pipe 500 slides along the trend, further the powder attachment residue is reduced, at the moment, the baffle 602 turns downwards under the elastic deformation action of the arc-shaped elastic sheet 605, further the auxiliary oscillation mechanism 7 is driven to operate, further, so that the arc-shaped baffle rod 701 deforms, moves downwards in the groove, then the convex semicircle IV 704 and the convex semicircle III 702 continuously dislocate and collide, further generate oscillation, meanwhile, the powder flowing into the die holder 107 is vibrated similarly, the problem that the tabletting effect is affected due to the fact that the powder is fed in a valley pile shape is avoided, when the powder raw material is filtered by the second filter screen 501, the larger particle raw material can be forced to rapidly roll to the low point to flow into the arc-shaped pipeline 503 to enter the grinding box 200 under the action of the second filter screen 501 designed by the inclination angle and matched with the subsequent powder vibrating mechanism 6, then the powder baffle 502 can guide the falling of the material in the falling process of the raw material, the probability and the falling amount of the powder material mistakenly entering the arc-shaped pipeline 503 are reduced, when the particle raw material slides to the grinding box 200 along the trend, the servo motor 402 drives the conical frustum prism 204 to rapidly rotate, the particle raw material is ground to be powdered to gradually flow to the first filter screen 202 arranged at the bottom of the conical frustum prism 204 under the action of the grinding saw teeth 201, and the first filter screen 202 is arranged to prevent the particle raw material which is not ground to be powdered from entering the material suction pipe 3, thereby influence the efficiency of shaping preforming, the particulate matter raw materials in filter screen 202 finally becomes powder or qualified little particulate matter under the effect of grinding sawtooth 201, and the material pipe 3 is inhaled to the flow direction, then carries to the inside continuation circulation of raw materials tank 102 through inhaling material pipe 3 and gets into above-mentioned corresponding mechanism, and cylinder 108 drives the mould seat 107 and rises under final, goes up cylinder 105 and drives the powder of flaking board 106 decline in with the mould seat 107 and press into comparatively even preforming.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; the present invention has been described in detail with reference to the foregoing embodiments, and it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
