The working principle of the invention is explained below, firstly, a tin salt block for preparing tin powder is put into a rectangular bin 2, then a first screw 12 is driven by a motor to rotate, the first screw 12 drives a first driving seat 14 and a movable block 6 to move through threads, meanwhile, the first screw 12 drives a first bevel gear 22 and an intermediate shaft to rotate through a second bevel gear 21, the intermediate shaft drives the first screw 12 on the other side to rotate through the bevel gear, the first screws 12 on the two sides rotate in opposite directions, so that the movable blocks 6 move in opposite directions, and a sealing tape connecting the two movable blocks 6 can move along a sliding groove 66 through a roller 5 due to the opposite moving directions of the movable blocks 6, so that the rectangular hole 3 can be always sealed, and dust or powder is prevented from entering the rectangular hole 3; in the moving process, the first motor 11 drives the first chain 19 to rotate through the second chain wheel 18, the first chain 19 drives the first chain wheel 13 to rotate, so that the rolling shaft 7 and the roller 8 are driven to rotate, the roller 8 rolls on the first filter plate 23 to crush the tin salt blocks, and the roller 8 is driven to move back and forth through the first screw 12, so that the tin salt blocks are fully crushed, and the powder enters the grinding mechanism through the first filter holes 24 to be fully ground for the second time;
powder falls onto the two grinding wheels and the baffle 40 along the discharge pipe 25, and then the motor II drives the bevel gear V42 and the inner shaft 27 to rotate through the bevel gear V44; at the moment, under the action of the one-way bearing, the bevel gear six 43 rotates relative to the outer shaft 26, and the outer shaft 26 does not move; at the moment, the inner shaft 27 drives the first straight gear 31, the first grinding shaft 29 and the second grinding shaft 30 to rotate through the second straight gear 32, so that the first grinding wheel 33 and the second grinding wheel 34 rotate, the first grinding wheel 33 and the second grinding wheel 34 rotate in opposite directions, the first grinding wheel 33 and the second grinding wheel 34 grind powder firstly, and when the powder is ground to enter a space between the first groove 331 and the second groove 35, the first groove 331 and the second groove 35 cut powder particles left and right, so that the diameter of the reduced powder particles is further increased; the particles meeting the requirements fall onto the semicircular plate 41 from the horizontal plate 361 through the second filtering hole 37, and finally enter the storage box through the third filtering hole; the first transition plate 38 and the second transition plate 39 prevent the unground powder from entering the bottom; the first transition plate 38 and the second transition plate 39 can also be provided with a first groove 331 and a second groove 35 which are matched with the first grinding wheel 33 and the second grinding wheel 34 for grinding; because part of the powder can directly fall onto the semicircular plate 41 along the discharge pipe 25, the motor II is required to drive the bevel gear six 43 and the outer shaft 26 to rotate through the bevel gear seven 44, and the bevel gear five 42 rotates relative to the inner shaft 27 under the action of the one-way bearing; baffle 40 can paste half-round plate 41 and rotate, and on the one hand baffle 40 can push the granule on the half-round plate 41 and get into the receiver along filtering hole three, and on the other hand part granule that meets the requirements can be shoveled by baffle 40, and after baffle 40 rotated a week, the granule that shovels up can get into again and grind between grinding wheel 33 and the grinding wheel 34.
The foregoing shows and describes the general principles, principal features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
