Therefore, they cannot be understood as limiting the present invention.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] Example 1,

[0031] See Figures 1-6 The utility model discloses a cutterhead mounting structure, including a cutterhead assembly and an adjustment assembly. The cutterhead assembly includes a cutterhead seat 10, a first cutterhead 20, and a second cutterhead 30. A first connecting portion is provided on the first cutterhead 20. The adjustment assembly includes a first adjustment ring 40 and a second adjustment ring 50. The first adjustment ring 40 is connected to the cutterhead seat 10. The first adjustment ring 40 is provided with a first guide portion; the second adjustment ring 50 is rotatably engaged with the first adjustment ring 40. The second adjustment ring 50 is provided with a second guide portion 52 and a second connecting portion. The second connecting portion is detachably connected to the first connecting portion to allow the second adjustment ring 50 to be detachably connected to the first cutterhead 20; the second guide portion 52 is movably engaged with the first guide portion to guide the second adjustment ring 50 to move along its own axial direction to adjust the distance between the first cutterhead 20 and the second cutterhead 30.

[0032] When the second cutter disc 30 is in the working state, the first cutter disc 20 is rotated and the second ...

[0033] In this embodiment, the first adjustment ring 40 and the second adjustment ring 50 are assembled on the cutter disc holder 10, so the assembly accuracy and relative position between the two are not affected by the assembly of the first cutter disc 20. When the first cutter disc 20 is installed, the first connection portion of the first cutter disc 20 is connected to the second connection portion of the second adjustment ring 50. During the assembly process, the second adjustment ring 50 does not rotate due to the installation of the first cutter disc 20. Therefore, after the first cutter disc 20 is installed, the relative position of the first adjustment ring 40 and the second adjustment ring 50 is the preset starting position. When the first cutter disc 20 is removed, the first connection portion of the first cutter disc 20 is disconnected from the second connection portion of the second adjustment ring 50. Even if it is installed again, the relative position of the second adjustment ring 50 and the first adjustment ring 40 does not need to be adjusted to the starting position, which facilitates operation.

[0034] It should be emphasized that the cutter disc seat 10 in this embodiment is used as an assembly base for structures such as the first cutter disc 20, the second cutter disc 30, the first adjustment ring 40, and the second adjustment ring 50. When used in a coffee machine, the cutter disc seat 10 can be a machine base. When used in a bean grinder, the cutter disc seat 10 can be a bean grinding knife seat. There is no specific limitation.

[0035] Of course, the above-mentioned first guide part and the second guide part 52 can be a threaded structure, specifically, a first thread segment is set on the first adjustment ring 40, and a second thread segment is correspondingly set on the second adjustment ring 50 to cooperate with it. When adjusting the position of the cutter disc, by rotating the first adjustment ring 40 or the second adjustment ring 50, in this embodiment, by rotating the first adjustment ring 40, when the first adjustment ring 40 rotates, the first thread segment and the second thread segment are threadedly matched to realize the axial position adjustment of the second adjustment ring 50, thereby adjusting the distance between the first cutter disc 20 and the second cutter disc 30.

[0036] Furthermore, the first guide portion may also be a guide post, and the second guide portion 52 may be a corresponding spiral groove or arcuate groove. When the first adjustment ring 40 rotates, the guide post of the first adjustment ring 40 slides within the spiral groove or arcuate groove structure, thereby guiding the second adjustment ring 50 up and down, thereby achieving movement of the first cutter disc 20 and adjusting the distance between the first cutter disc 20 and the second cutter disc 30. The specific structures of the first guide portion of the first adjustment ring 40 and the second guide portion 52 of the second adjustment ring 50 are not limited in this application.

[0037] Furthermore, a clamping block 23 can be provided on the first cutter disc 20, and a corresponding clamping groove 51 can be provided on the second adjustment ring 50. When the first cutter disc 20 is assembled to the second adjustment ring 50, the clamping block 23 on the first cutter disc 20 corresponds to the clamping groove 51 of the second adjustment ring 50, and the clamping block 23 is clamped into the clamping groove 51. Based on this structure, the clamping block 23 is the above-mentioned first connecting part, and the clamping groove 51 is the above-mentioned second connecting part.

[0038] The first cutter head 20 and the second adjustment ring 50 are detachable by means of a snap connection. During assembly, the first cutter head 20 is directly snapped into the snap-in slot 51 with the snap-in block 23. The snap-in slot 51 and the snap-in block 23 are locked in position, making assembly and disassembly convenient. Furthermore, after the snap-in block 23 is snapped into the snap-in slot 51, it can fill the slot, making the assembly structure more stable.

[0039] Of course, a snap can be directly provided on the first cutter disc 20, and a corresponding snap can be provided on the second adjustment ring 50, so that the snap and the snap can achieve a snap connection. Alternatively, a spring pin can be provided on the first cutter disc 20, and a spring pin hole can be provided on the second adjustment ring 50, and the spring pin can be inserted into the spring pin hole to achieve detachable assembly. More specifically, a snap interface is provided in the snap groove 51, and the opening of the snap interface is arranged circumferentially toward the second adjustment ring 50. When the first cutter disc 20 is assembled, when the first cutter disc 20 is installed into the second adjustment ring 50, the snap block 23 on the first cutter disc 20 is first staggered circumferentially with the snap interface of the snap groove 51, so that the first cutter disc 20 is not blocked during installation. Then, the snap block 23 aligns with the snap interface of the snap groove 51. Then, the first cutter disc 20 is rotated, and the snap block 23 of the first cutter disc 20 snaps into the snap groove 51 via the snap interface, achieving a snap connection between the first cutter disc 20 and the second adjustment ring 50.

[0040] It should be noted that compared with the card interface of the card slot 51 being set in the axial direction, although the first cutter disc 20 can be directly installed from above, it is more convenient and simple for the card block 23 to be directly inserted into the card slot 51 from top to bottom. However, during use, the first cutter disc 20 is also prone to detachment from the second adjustment ring 50.

[0041] Therefore, in this embodiment, the clamping block 23 of the first cutter disc 20 is rotated into the clamping groove 51 from the circumferential direction, and the top wall of the clamping groove 51 can be limited above the clamping block 23. After installation, the clamping block 23 is not easy to detach from the top, and the assembly structure is more stable.

[0042] More specifically, a limiting rib 511 can be provided in the clamping groove 51, and a corresponding limiting groove 231 is provided on the clamping block 23. After the clamping block 23 is rotated to the clamping groove 51, the limiting rib 511 in the clamping groove 51 can be clamped into the limiting groove 231. In this way, the limiting rib 511 and the limiting groove 231 are clamped together to prevent the clamping block 23 from being separated from the clamping groove 51 in the circumferential direction. That is, after the clamping block 23 is clamped into the clamping groove 51, the limiting rib 511 and the limiting groove 231 are used to limit the clamping block 23 in the circumferential direction, and the top wall of the clamping groove 51 is used to limit the clamping block 23 in the axial direction, so that the assembly is more stable.

[0043] Furthermore, if a limiting rib 511 and a limiting groove 231 structure are set, the clamping block 23 is easily blocked by the limiting rib 511 during the clamping process. In order to prevent the clamping block 23 from getting stuck, the limiting groove 231 is an arc groove, and the outer surface of the limiting rib 511 is an arc surface. During the clamping process, a smooth transition is made with the arc surface, and it is not easy to get stuck.

[0044] Of course, the above-mentioned limiting ribs 511 can also be realized by an elastic rubber structure. The elastic rubber is easy to deform after being compressed, and can avoid it during the process of the clamping block 23 being clamped in, so that it can be smoothly clamped in or out.

[0045] Furthermore, a first guiding bevel can be provided on the top wall of the snap-in groove 51, corresponding to a second guiding bevel at the top end of the snap-in block 23. When the snap-in block 23 is snapped into the snap-in groove 51, the first guiding bevel and the second guiding bevel slide together. Specifically, the first guiding bevel gradually tilts downward from one side of the card interface to the side away from the card interface. In this way, the second guiding bevel is gradually pressed during the snap-in process of the snap-in block 23, thereby tightening the snap-in block 23. In this way, the structure is more stable after snapping.

[0046] Furthermore, the outer surfaces of both sides of the above-mentioned first cutter disc 20 are provided with clamping blocks 23, and the inner surface of the second adjustment ring 50 is provided with clamping grooves 51 on both sides. When the first cutter disc 20 is assembled, when the first cutter disc 20 and the second adjustment ring 50 are assembled, the first cutter disc 20 is inserted into the inner side of the second adjustment ring 50, that is, the second adjustment ring 50 is mounted on the outer surface of the first cutter disc 20, and the connection structure between the clamping block 23 and the clamping groove 51 is located on the inner side to prevent the assembly structure from being exposed.

[0047] The two clamping blocks 23 of the first cutter disc 20 are clamped one by one with the two clamping grooves 51 of the second adjustment ring 50, realizing clamping limitation on both sides. The first cutter disc 20 and the second adjustment ring 50 form two connection points, which are evenly distributed and the assembly structure is more stable.

[0048] Of course, during assembly, the first cutter disc 20 can also be mounted on the outside of the second adjustment ring 50. Based on this structure, the second guide portion 52 for cooperating with the first guide portion of the first adjustment ring 40 can be set on the inner side of the second adjustment ring 50.

[0049] Furthermore, in this embodiment, the first cutter disc 20 is provided with a connecting seat 21 and a metal cutter seat 22, that is, the first cutter disc 20 is composed of a two-part structure. The connecting seat 21 can be made of hard plastic material, which is convenient for processing the clamping block 23 or other connecting structures on the connecting seat 21, and the cost is low. The metal cutter seat 22 is provided with a plurality of blades 221, and the structure for setting a plurality of cutter discs is made of metal material, which has better strength.

[0050] During assembly, the metal knife seat 22 and the connecting seat 21 can be assembled using structures such as screws. After the blades 221 of the metal knife seat 22 are worn, the metal knife seat 22 can be replaced.

[0051] Furthermore, since the first cutter disc 20 is detachably mounted to the second adjustment ring 50, a rotatable handle 211 is rotatably provided on the connecting base 21 to facilitate installation or removal. When installing or removing the first cutter disc 20, the rotatable handle 211 can be rotated to a vertical position, and the user can hold the rotatable handle 211 to operate the first cutter disc 20. After the first cutter disc 20 is installed in place, the rotatable handle 211 can be stored in a horizontal position.

[0052] Example 2,

[0053] This embodiment also provides a coffee machine, including the cutter disc mounting structure of the above-mentioned embodiment 1, and the cutter disc mounting structure is installed on the base of the coffee machine. The cutter disc seat 10 of the above-mentioned cutter disc mounting structure can be fixedly connected to the base, or can be formed by the base of the coffee machine. After the cutter disc mounting structure is assembled to the coffee machine, the second cutter disc 30 can be set on the base of the coffee machine, and driven by the driving structure of the coffee machine to rotate, cooperating with the first cutter disc 20 to grind the coffee beans.

[0054] It should be noted that the function structure and principle of the specific blade disc mounting structure for the coffee machine are the same as those in Example 1, and the other structures of the coffee machine are all existing technologies and will not be described in detail here.

[0055] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features.
