The knife sleeve 6 is arranged on the bean grinding adjusting seat 8 through the knife sleeve frame 7 and is static relative to the main shaft 13. When the motor 1 drives the spindle 13 to rotate, the coffee beans are ground between the cutter head 10 and the sleeve 6. The ground coffee powder falls into the lower powder throwing disc 12 through the gap between the cutter head 10 and the cutter sleeve 6. An impeller 20 is arranged on a powder throwing disc 12 fixed on the main shaft 13, and the powder falling into the coffee powder grinding bean box 4 is thrown out from a powder outlet thereof through the rotation of the impeller 20. The fineness of the ground coffee powder can be adjusted by adjusting the gap between the cutter head 10 and the cutter sleeve 6. A spiral bean stirring head 9 is arranged above the cutter head 10 and the cutter sleeve 6. The spiral stirring bean head 9 is used for stirring the coffee beans entering the bean grinder, so that the coffee beans enter a gap between the cutter head 10 and the cutter sleeve 6.
The big gear 11 for adjusting the thickness is arranged outside the bean grinding adjusting seat 8. The inside of the thickness adjusting large gear 11 is provided with a distance adjusting thread 18. The outer part of the bean grinding adjusting seat 8 is provided with a distance adjusting flange 19.
