Since the support plate 3 is threadedly connected and slidably connected with the threaded shaft 6 and the vertical shaft 7 respectively, the support plate 3 can be driven to move vertically, adjust the height of the grinding roller 16, and thus adjust the distance between the grinding roller 16 and the inclined surface 17 on the inner wall of the grinding cylinder 2, so as to adjust the grinding particle size.

[0030] Refer to Figure 2-3 , Both inner walls on both sides of the main body 1 are fixedly installed with blowers 19. Both sides of the bottom of the grinding cylinder 2 are communicated with air inlet pipes 23. The lower end of the air inlet pipe 23 is communicated with a one-way valve 24. The lower end of the one-way valve 24 is pipe-connected with the output end of the blower 19. Exhaust holes 20 are symmetrically opened on both sides of the upper part of the grinding cylinder 2. A filter cloth 21 matching the exhaust holes 20 is fixedly installed inside the exhaust holes 20; The blower 19 can transport air into the grinding cylinder 2 through the air inlet pipe 23. The air passes through the grinding roller 16 and the inclined surface 17, and finally is discharged through the exhaust holes 20, so as to blow up the accumulated ground milk powder at the grinding roller 16 and the inclined surface 17, and prevent the situation of unsmooth feeding after grinding is completed.

[0031] Refer to Figure 3 , The flow direction of the one-way valve 24 is from bottom to top; The one-way valve 24 prevents the ground milk powder from entering the blower 19.

[0037] Working principle: During use, the milk powder raw material to be ground is transported into the grinding cylinder 2 through the feeding pipe 14, and the driving motor 4 drives the grinding roller 16 through the rotating shaft 5, so that the milk powder at the grinding roller 16 and the inclined surface 17 can be ground. The ground milk powder falls to the bottom of the grinding cylinder 2 and is finally collected into the collection box 18 through the discharge pipe 15; by driving the first bevel gear 9 to rotate through the adjusting motor 8, the first bevel gear 9 drives the threaded shaft 6 to rotate through the second bevel gear 10. Since the support plate 3 is threadedly connected and slidably connected to the threaded shaft 6 and the vertical shaft 7 respectively, the support plate 3 can be driven to move vertically, adjusting the height of the grinding roller 16, thereby adjusting the distance between the grinding roller 16 and the inclined surface 17 of the inner wall of the grinding cylinder 2, so that the grinding particle size can be adjusted, which is flexible and convenient to use. And when the ground milk powder at the grinding roller 16 and the inclined surface 17 accumulates and cannot be discharged, the blower 19 can send air into the grinding cylinder 2 through the air inlet pipe 23. The air passes through the grinding roller 16 and the inclined surface 17 and is finally discharged through the exhaust hole 20, so that the accumulated ground milk powder at the grinding roller 16 and the inclined surface 17 can be blown up to prevent the situation of unsmooth discharging after grinding.
