The interval width between the side groove parts 8 is slightly larger than the self width of the side groove parts 8, and under the condition that the position relation of the two groups of milling roller bodies 5 is adjusted to be that the interval between the side groove parts 8 and the side groove parts 8 alternately correspond, the two groups of milling roller bodies 5 rotate at the same speed and in opposite directions, so that grains carried on the negative pressure milling box 6 can be ensured to squeeze the other group of milling roller bodies 5 for milling; the problem that grains carried by the two groups of negative pressure milling boxes 6 are contacted and mutually affected does not occur.
The negative pressure grinding box 6 consists of a square part 9 and a fan-shaped part 10, wherein the edge of the square part 9 is provided with an arc-shaped hard edge 11 which is anastomotic with the grinding roller body 5, ratchet-shaped meshes 12 are arranged on the arc-shaped hard edge 11 in an array manner, fan-shaped extension parts 13 are symmetrically arranged at two ends of the fan-shaped part 10, the fan-shaped extension parts 13 are clamped and arranged in the neck tube part 7, a fan-shaped opening 14 is arranged at the fan-shaped extension part 13 at one end, and a fan-shaped sealing plate 15 is arranged at the fan-shaped extension part 13 at the other end.
The combined type grinding roller mechanisms 1 are provided with two groups, the two groups of combined type grinding roller mechanisms 1 are arranged in a transverse array, and a preset gap exists between the two groups of combined type grinding roller mechanisms 1; the negative pressure grinding boxes 6 on the two sets of grinding roller bodies 5 are alternately distributed, and when the negative pressure grinding boxes 6 rotate to the middle transverse position, the side wall of the other set of grinding roller bodies 5 is correspondingly arranged.
Through the suction of the negative pressure flow distribution mechanism 2 to the air flow in the negative pressure grinding box 6, negative pressure can be formed in the negative pressure grinding box 6, so that the technical purpose of adsorbing grains is realized at the ratchet-shaped mesh 12, and because continuous air flow exists in the negative pressure grinding box 6 in the grinding area, dust and particles with too small volume in the grinding process can enter the negative pressure grinding box 6 and the flow distribution pipe 17 through the ratchet-shaped mesh 12, and the grain size of a finished product can be ensured not to be too small in this way.
By designing the gap between the two sets of milling roller bodies 5 and designing the aperture of the ratchet-shaped mesh 12, the grain size range of the milled product can be determined, and the product grains are ensured not to be too large or too small, so that the product can meet the relatively higher product grade requirement.

In the automatic feed assembly 21, the material is stacked on the material carrying plate 25, and the load variation of the feed spring 26 during the material consumption is equal to the variation of the material:
wherein: g-load, m-mass, G-gravitational acceleration, ρ -material density, V-material volume, S-cross sectional area of the loading plate 25, h-elevation height of the loading plate 25.
Whereas for the feed spring 26, the spring force formula can be expressed as:
wherein: the spring force variation of F-spring, the k-stiffness coefficient, the length variation of the fatx-spring.
In the above two formulas, since G and F are equal in the equilibrium state, and (ρ×s×g) and (k) are fixed constants, by designing the values of (ρ×s×g) and (k), the two parameters of x and h can be kept equal, so that the technical purpose that the rising amplitude of the loading plate 25 along with the material consumption is equal to the material consumption amplitude is achieved, and the top of the material is ensured to be always closely attached to or close to the outer contour of the grinding roller body 5.
When the automatic rolling machine is specifically used, firstly, a user needs to load materials on a material loading plate 25, the top of the materials is tightly attached to or close to the outer contour of a rolling roller body 5 in an initial state, then, when external negative pressure is started to extract air in a negative pressure rolling box 6 through a flow distribution pipe 17, a driving motor 30 is started, and two groups of rolling roller bodies 5 are simultaneously rotated at the same speed and in opposite directions through a driving gear 31, a driven gear I32 and a driven gear II 33;
because negative pressure is formed in the negative pressure grinding box 6, external air can continuously enter the negative pressure grinding box 6 through the ratchet-shaped mesh 12, then flows through the fan-shaped extension part 13, the fan-shaped opening 14 and the flow distribution joint 18, and finally is conveyed to the outside through the flow distribution pipeline 19 and stored;
under the action of negative pressure, grains near the arc-shaped hard edge 11 are adsorbed and blocked on the ratchet-shaped mesh 12 and rotate along with the negative pressure grinding box 6, when the grains rotate to a position nearest to the other group of grinding roller bodies 5, the grains are ground into small particles under the extrusion of the arc-shaped hard edge 11 and the side walls of the other group of grinding roller bodies 5, and the size of the particles is mainly determined by the size of a gap between the two groups of combined grinding roller mechanisms 1;
the broken grains are mainly divided into two categories:
firstly, the crushing is completed and the size is proper, as the crushing increases the number of particles, a part of qualified particles continue to be adsorbed and move upwards, and the other part of qualified particles drop back onto the material carrying plate 25 and are picked up in the following circulation, and the other group of grinding roller bodies 5 are not contacted when passing through the gap due to the fact that the qualified particles are crushed, and therefore, the qualified particles directly follow the movement to the top;
secondly, dust and fine scraps generated in the crushing process can influence the quality grade of the product if the scraps are mixed in the finished product, and under the continuous negative pressure of the negative pressure grinding box 6, the fine scraps can be sucked into the negative pressure grinding box 6 through the ratchet-shaped mesh 12 and then conveyed out and stored;
through the design of the stiffness coefficient of the feed spring 26 and the area of the material carrying plate 25, the technical aim that the rising amplitude of the material carrying plate 25 along with the consumption of materials is equal to the consumption amplitude of the materials can be realized; and because the negative pressure grinding box 6 adopts a negative pressure adsorption mode and has a certain effective action range, certain errors and delays can be allowed to exist in the following motion of the automatic feeding assembly 21.
After the material which is crushed and moves along with the negative pressure grinding box 6 passes through the highest point, the grains are separated from the ratchet-shaped mesh 12 after the continuous negative pressure is lost due to the blocking of the fan-shaped flow distribution plate 16 to the negative pressure grinding box 6, and roll down onto the collecting plate 23 along the combined grinding roller mechanism 1, so that the grinding and sorting of the grains are completed.
