Eccentric wheel 3 constitutes revolution mechanic through first gear 4 and blanking post 1, and first gear 4 and second gear 5 intermeshing, and second gear 5 drives first gear 4 synchronous revolution, reduces the use of motor.
The diameter of the first through hole 6 is the same as that of the hole 14, and the rotating gear 8 and the support plate 7 form a rotating structure through the half gear 10, so that gap blanking is realized.
The support plate 7 is of an isosceles trapezoid structure, and the first through holes 6 formed in the support plate 7 are uniformly distributed, so that particles cannot be left above the support plate 7.
The diameter of the half gear 10 is smaller than that of the rotating gear 8, and the rotating gear 8 and the blanking column 1 form a rotating structure through the half gear 10, so that the half gear 10 can drive the rotating gear 8 to rotate conveniently.
