[0006] By adopting the above technical scheme, the coffee powder grinding device comprises a corresponding circular inner grinding disc body and an outer grinding disc body, the inner grinding disc is arranged in the outer grinding disc body, the inner grinding disc is provided with multiple protrusions, the outer grinding disc is provided with grooves corresponding to the protrusions, and the protrusions cooperate with the grooves. The outer grinding disc body is provided with a material inlet and a material outlet, the material to be ground enters through the material inlet, the ground material flows out from the material outlet, the protrusions and the grooves between the inner grinding disc and the outer grinding disc cooperate to realize the grinding of the material to be ground, the structure is simple, convenient to carry, and the production cost is effectively reduced under the premise of ensuring the uniformity of the ground powder particles. BRIEF DESCRIPTION OF DRAWINGS
[0007] Figure 1 It is a schematic diagram of the coffee powder grinding device of the present application; Figure 2 is a schematic view of the inner grinding disc body; Figure 3 is a schematic view of the outer grinding disc body; Figure 4 is the periodic engagement motion trajectory of the inner grinding disc protrusions and the outer grinding disc concave recesses; Figure 5 is the left-right alternating regular back-and-forth swinging trajectory of the inner grinding disc protrusion bevels and the outer grinding disc concave recess bevels. DETAILED DESCRIPTION
[0008] The specific embodiments of the present application are further described below in conjunction with the accompanying drawings.
[0009] See Figure 1 , Figure 3 and Figure 3 , a coffee powder grinding device, which comprises a corresponding circular inner grinding disc body 1 and an outer grinding disc body 2, the outer grinding disc body 1 is provided with a material inlet 3 and a material outlet 4, the inner grinding disc body 1 is arranged in the outer grinding disc body 2, the inner grinding disc 1 is provided with a plurality of protrusions 5, the outer grinding disc 2 is provided with a plurality of recesses 6 corresponding to the protrusions 5, the protrusions 5 and the recesses 6 are matched, coffee bean material enters through the material inlet, and the ground material flows out from the material outlet, the matching of the protrusions and the recesses between the inner grinding disc and the outer grinding disc realizes the grinding of the coffee bean material, the structure is simple, convenient to carry, and the production cost is effectively reduced under the premise of ensuring uniform distribution of coffee powder particles.
[0010] The inner grinding disc body 1 is connected to a center shaft 7, the center shaft 7 is a eccentric shaft structure, the center shaft 7 is inclined to the center 8 of the inner grinding disc body, preferably the center shaft 7 is at a certain angle with the center 8 of the inner grinding disc body, the center shaft of the inner grinding disc is not completely centered, but is offset by a certain amount and has a certain angle with the theoretical center shaft, the angle between the center shaft and the center of the inner grinding disc body is determined according to the angle of the protrusion and the recess slope surface matched by the inner grinding disc and the outer grinding disc, to ensure the normal rotation of the inner grinding disc body. Thus, the inner grinding disc has relative periodic motion with the outer grinding disc on the X and Y axes, first, the periodic engagement motion of the inner grinding disc protrusions and the outer grinding disc concave recesses ( Figure 4 ), second, the left-right alternating regular back-and-forth swinging of the inner grinding disc protrusion bevels and the outer grinding disc concave recess bevels ( Figure 5 ).
[0011] Because the size, shape and hardness of the material are not the same, in order to ensure a certain grinding efficiency, the protrusions 5 on the inner grinding disc body 1 are conical protrusions, but not limited to conical protrusions (semicircular, sharp angle, trapezoidal, rectangular, etc.), and the outer grinding disc body (relatively fixed) has a concave recess corresponding thereto, forming a concave-convex matching working surface, to ensure the grinding effect of coffee.
[0012] The bottom groove of the outer grinding disc body 1 is connected with the material outlet 4 through the formed discharge groove 9, so that the multi-groove simultaneous discharge is realized, the overall structure of the coffee powder grinding and milling device is simplified, and the production cost is further reduced.
[0013] In the present application, the inner grinding disc body center shaft is supported through a support, and the coffee powder grinding and milling device is arranged in the shell, and the shell can also be used as a support for the inner grinding disc body center shaft.
[0014] The above is the preferred embodiment of the present application, and is not any form of limitation on the present application. Any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present application are within the scope of the technical solution.
