When the powder pressing component 32 rotates in the other direction (clockwise direction in the top view of fig. 9), the powder falling on the powder guide surface 3222 falls into the powder receiver 31 from the powder guide channel 323 under the inertia effect of the rotation of the powder pressing block 322, and the powder pressing block 322 can compact the powder falling into the powder receiver 31, so that the powder pressing component 32 can rotate in one direction to press powder.

Specifically, in some embodiments, the first spiral track and the second spiral track rotate in opposite directions, such that the abrasive member 22 grinds the powder and the powder pressing member 32 idles when the driver 41 rotates in one direction, and the powder pressing member 32 presses the powder and the abrasive member 22 idles when the driver 41 rotates in the other direction.

Specifically, in some embodiments, the handle 312 is disposed on the powder receiving device 31, and the main body 10 further defines a powder receiving cavity, which is located below the blanking channel 4621 of the output gear 462. Be equipped with a plurality of supporting shoes on the inner wall that connects the powder chamber, connect to be equipped with a plurality of hangers on the powder ware 31, the supporting shoe upper surface be equipped with the shape assorted recess of hanger, the hanger butt card is established in the recess after on the supporting shoe, when the powder part 32 rotates, prevents through the spacing of recess that to connect powder ware 31 also to rotate because the frictional force drive of powder part 32, guarantees the effect of powder compaction.

The supporting blocks and the hanging lugs are arranged at intervals along the circumferential direction of the powder collector 31, and a shuttling gap is formed between every two adjacent supporting blocks. The opening of the powder receiving cavity is located at the lower end of the main body 10, when the powder receiving device 31 is installed, the handle 312 of the powder receiving device 31 is held, so that the powder receiving device 31 moves upwards from the opening of the powder receiving cavity, the hanging lugs of the powder receiving device 31 pass through the shuttle gap and move to the upper portion of the supporting block, then the powder receiving device 31 is horizontally rotated, so that the hanging lugs are located right above the supporting block, and finally the powder receiving device 31 is placed on the supporting block through the hanging lugs.

The working principle of the grinding machine is as follows:

adding raw materials into an abrasive channel of the abrasive device 20, wherein the raw materials are coffee bean all particle raw materials, starting a driver 41 to rotate along a first direction, driving a first transmission shaft 42 to rotate along the first direction by the driver 41, and driving an abrasive part 22 to rotate by the first transmission shaft 42 to grind the raw materials in the abrasive channel into powder;

after the abrasive member 22 grinds for a preset length of time, the driver 41 stops;

starting the driver 41 to drive the first transmission shaft 42 to rotate along a second direction opposite to the first direction, driving the powder pressing part 32 to rotate by the first transmission shaft 42 through the second transmission shaft 43, enabling the ground raw materials to sequentially fall into the powder storage groove 311, and compacting the ground raw materials in the powder storage groove 311 while rotating the powder pressing part 32;

as the height of the pulverized material in the powder storage tank 311 increases, the powder pressing member 32 gradually rises and pushes the second transmission shaft 43 to slide in a direction away from the powder storage tank 311;

after the powder pressing member 32 is rotated to compact for a preset time, the driver 41 is stopped;

finally, the powder receiver 31 is taken down, and the powder pressing part 32 falls down under the action of gravity and a spring until the powder pressing part descends to the initial position.

The above examples are not intended to be exhaustive list of the present invention, and there may be many other embodiments not listed. Any replacement and improvement made on the basis of not violating the conception of the utility model belong to the protection scope of the utility model.
