the right two through holes 31 are driven to rotate through the right two tenth transmission shafts 69, the right two sixth gears 54 are driven to rotate through the through holes 31, the metal rod is fed into the metal rolling cavity 12 from the outside through the metal rod inlet 18 under the extrusion of the second gear 14 and the first gear 16, the metal rod is rolled to the right under the extrusion of the second gear 14 and the first gear 16, the metal rod is driven to move to the conveyor belt 29, the clockwise rotating fourth belt wheel 74 drives the metal rod to enter the grinding cavity 70 through the left through hole 31 through the conveyor belt 29, and the metal rod rotates around the central axis of the through hole 31 and moves rightwards under the clamping of the sixth gear 54 and the fifth gear 32, the rotating grinding wheel 52 grinds the metal rod, an oxide layer on the metal rod is taken out, finally the metal rod moves out of the outside through the through hole 31 at the right side, the rolling grinding work is completed, in the process, the generated metal powder enters the collection cavity 71 through the connecting hopper 48 and falls into the first collection container 45 placed on the sliding disc 37, when the weight of the first collection container 45 is increased, the sliding disc 37 is driven to move downwards, the first spring 40 accumulates elastic potential energy, the sliding disc 37 moving downwards sequentially passes through the fixed connecting rod 39, the connecting rod 22 and the twelfth transmission shaft 21 to drive the fifth bevel gear 23 to move downwards until the fifth bevel gear 23 is simultaneously meshed with the seventh bevel gear 24 and the sixth bevel gear 20, and the rotating fifth transmission shaft 19 sequentially passes through the fifth bevel gear 23, the fourth, The seventh bevel gear 24, the seventh transmission shaft 25, the first belt pulley 27 and the first belt 28 drive the second belt pulley 33 to rotate, the rotating second belt pulley 33 sequentially passes through the fourth transmission shaft 38 and the fixed support 34 to drive the limit rotary table 35 to rotate, the torsion spring 36 accumulates elastic potential energy, then the first collecting container 45 filled with metal powder is moved to the outlet slide way 60 through the limit groove 79 and is moved out of the outside through the container outlet 59, at the moment, the first spring 40 releases the elastic potential energy to drive the sliding disc 37 to reset, at the moment, the fifth bevel gear 23 is not meshed with the sixth bevel gear 20 and the seventh bevel gear 24 any more, the limit rotary table 35 loses power, the torsion spring 36 releases the elastic potential energy to drive the limit rotary table 35 to reset, the electromagnet 61 detects that the collecting container 45 does not exist on the sliding disc 37 any more, so that the electromagnet is electrified and magnetic, the limit rod 42 is attracted to move backwards, and the, at this moment, the second collecting container 45 on the inlet slide way 44 slides into the sliding disc 37 under the action of gravity, the limiting groove 79 limits the second collecting container 45 at this moment, when the electromagnet 61 senses that the collecting container 45 exists on the sliding disc 37, the power failure does not have magnetism, the second spring 80 releases elastic potential energy at this moment, the limiting rod 42 is driven to reset, the limiting rod 42 is abutted against the third empty collecting container 45 at this moment, the third collecting container 45 is not contacted with the second collecting container 45, the steps are repeated, and uninterrupted work is realized.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
