The terms used in the specification of the utility model herein are only for the purpose of describing the specific embodiments and are not intended to limit the utility model.

[0030] Reference is made to Figures 1-7The utility model discloses a cutter head adjusting assembly, including first adjusting ring 10, second adjusting ring 20 and rotation stop piece, first adjusting ring 10 can rotate under the action of external force, and first adjusting ring 10 is equipped with first guide portion 12. The second adjusting ring 20 of the above-mentioned and first adjusting ring 10 rotate and cooperate, and second adjusting ring 20 is equipped with second guide portion 22 and rotation stop portion, when first adjusting ring 10 rotates, second guide portion 22 can be movable with first guide portion 12, and when second guide portion 22 is movable with first guide portion 12, can guide second adjusting ring 20 along an axial movement, and second adjusting ring 20 is connected with cutter head 40.

[0031] In addition, the rotation stop piece can abut against the rotation stop portion to limit the rotation of the second adjusting ring 20, and the rotation stop piece and the rotation stop portion are axially slidingly connected.

[0032] It should be noted that the cutter head adjusting assembly in the embodiment can be used on a coffee machine or a bean grinder, and is used for adjusting the position of the cutter head 40 on the coffee machine or the bean grinder. Two cutter heads 40 can be arranged on the coffee machine, and the second adjusting ring 20 is connected with one of the cutter heads 40, so that the distance between the cutter heads 40 can be adjusted, and the grinding gap is adjusted.

[0033] Based on the above structure, when the cutter head adjusting assembly of the utility model is used, the cutter head 40 is installed on the base of the coffee machine or the bean grinder, the first adjusting ring 10 and the second adjusting ring 20 are rotatably connected, and when adjustment is performed, the first adjusting ring 10 is rotated, the rotation of the first adjusting ring 10 can drive the first guide portion 12 to movably connect with the second guide portion 22 on the second adjusting ring 20. At this time, the rotation stop piece can be close to the rotation stop portion of the second adjusting ring 20 under the action of external force, so that the rotation movement of the second adjusting ring 20 can be limited by the rotation stop piece, and the rotation stop piece and the rotation stop portion are slidingly connected. The second guide portion 22 and the first guide portion 12 are slidingly connected, and the sliding of the rotation stop piece and the rotation stop portion is simultaneously connected, so that the second adjusting ring 20 can move axially, and further drive the cutter head 40 to move, so that the distance between the cutter heads 40 is adjusted.

[0034] In the embodiment, the rotation stop piece can be assembled to the rotation stop portion of the second adjusting ring 20 after the first adjusting ring 10 and the second adjusting ring 20 are assembled, so as to limit the rotation movement of the second adjusting ring 20 and allow the second adjusting ring 20 to move axially. In this way, the rotation stop piece can be separately disassembled, and there is no need to additionally arrange a rotation stop part on the first adjusting ring 10 to cooperate with the second adjusting ring 20, so that the internal structure is not affected.

[0035] Of course, the first guide part 12 and the second guide part 22 can be a threaded structure, specifically, a first threaded segment is arranged on the first adjusting ring 10, and a second threaded segment corresponding to the first threaded segment is arranged on the second adjusting ring 20, when the position of the cutter head 40 is adjusted, the first adjusting ring 10 is rotated, the first threaded segment and the second threaded segment are threadedly matched, the axial position of the second adjusting ring 20 is adjusted, and the distance between the two cutter heads 40 is adjusted.

[0036] In addition, the first guide part 12 can also be a guide column, and the second guide part 22 can be a spiral groove or an arc-shaped groove, when the first adjusting ring 10 is rotated, the guide column of the first adjusting ring 10 slides in the spiral groove or the arc-shaped groove, and the up and down movement of the second adjusting ring 20 is guided, the movement of the cutter head 40 is realized, and the distance between the two cutter heads 40 is adjusted. The structure of the first guide part 12 of the first adjusting ring 10 and the second guide part 22 of the second adjusting ring 20 is not limited in the present application.

[0037] Further, the second adjusting ring 20 can be provided with a rotation-stopping groove 21 extending in the axial direction, and the rotation-stopping part is inserted into the rotation-stopping groove 21 and is in sliding fit with the rotation-stopping groove 21 when the rotation-stopping action is performed. After the rotation-stopping part is inserted into the rotation-stopping groove 21 of the second adjusting ring 20, the rotational movement of the second adjusting ring 20 is limited, the rotation-stopping part slides in the axial direction of the rotation-stopping groove 21, and thus the second adjusting ring 20 can move in the axial direction of itself, and the position of the cutter head 40 is adjusted.

[0038] Of course, the second adjusting ring 20 can also be provided with a protruding rotation-stopping structure extending in the axial direction of the second adjusting ring 20, and the rotation-stopping part abuts against the rotation-stopping structure in the circumferential direction and slides in the axial direction, which can also achieve the rotation-stopping action and guide the axial sliding.

[0039] The rotation-stopping groove 21 is used as the rotation-stopping part, and when the rotation-stopping action is performed, the rotation-stopping part only needs to be inserted into the rotation-stopping groove 21, which prevents the rotation-stopping part from being separated during the rotation-stopping process, and the rotation-stopping action is more stable.

[0040] Further, the rotation-stopping part includes a rotation-stopping block 31 and an elastic component, and the rotation-stopping teeth 311 are arranged on the rotation-stopping block 31. The elastic component can provide an elastic stress, and under the action of the elastic stress, the rotation-stopping block 31 can be close to the rotation-stopping groove 21, so that the rotation-stopping teeth 311 are inserted into the rotation-stopping groove 21. In this way, when the rotation-stopping part is assembled, the rotation-stopping part is inserted into the rotation-stopping groove 21 by the elastic stress provided by the elastic component, and the force acting on the rotation-stopping part is an elastic force. Therefore, when the second adjusting ring 20 is driven by the first adjusting ring 10, the second adjusting ring 20 can have a tendency to move in the axial direction, and will not be stuck under the action of a hard force.

[0041] The specific rotation-stopping piece can be assembled based on the base of the coffee machine or the bean grinder, the rotation-stopping block 31 is connected to the base of the coffee machine or the bean grinder through the elastic component instead of being assembled to the first adjusting ring 10, and the rotation-stopping structure of the second adjusting ring 20 is additionally arranged on the base, so that the assembly space between the first adjusting ring 10 and the second adjusting ring 20 is not increased, and internal interference is reduced.

[0042] In addition, the rotation-stopping block 31 is engaged with the rotation-stopping groove 21 of the second adjusting ring 20 through the rotation-stopping teeth 311, so that the rotation-stopping groove 21 and the rotation-stopping teeth 311 are limited after the rotation-stopping teeth 311 of the rotation-stopping block 31 are inserted, and the rotation-stopping structure is more stable.

[0043] Further, a plurality of rotation-stopping grooves 21 are arranged in the circumferential direction of the second adjusting ring 20, at least two rotation-stopping teeth 311 are arranged on the rotation-stopping piece, and the rotation-stopping teeth 311 are inserted into the rotation-stopping grooves 21. A plurality of rotation-stopping grooves 21 are arranged in the circumferential direction, so that when assembled, the rotation-stopping teeth 311 of the rotation-stopping piece can be inserted into one of them, and it is not necessary to assemble one by one, so that the assembly difficulty is reduced.

[0044] Further, the end face of the rotation-stopping block 31 away from the rotation-stopping teeth 311 is provided with an abutting groove 312, the elastic component includes an elastic metal rod 32, the elastic metal rod 32 includes an elastic protruding section 321 and an elastic connecting section 322, both ends of the elastic protruding section 321 are connected with the elastic connecting section 322, and the elastic protruding section 321 is abutted into the abutting groove 312. On the basis of this structure, when the rotation-stopping piece is assembled, the rotation-stopping piece is assembled to the base, then the elastic connecting sections 322 at both ends of the elastic metal rod 32 are connected to the base respectively, so that the elastic protruding section 321 in the middle can be inserted into the abutting groove 312 of the rotation-stopping block 31, and is elastically pressed on the rotation-stopping block 31, so that the rotation-stopping piece can be stably pressed in the rotation-stopping groove 21 of the second adjusting ring 20.

[0045] Further, the rotation-stopping block 31 in the embodiment is a rubber block, and in other cases, the rotation-stopping block 31 can also be a silica gel block or a plastic block, etc., so that the elastic stress applied by the rubber block in cooperation with the elastic protruding section 321 is more flexible. The rubber block assembly can also increase the friction of the rotation-stopping groove 21 of the second adjusting ring 20, and can also prevent the disengagement.

[0046] Of course, the above-mentioned elastic component can also be selected as a spring in the prior art, compared with the spring which exerts elastic force in the length direction of itself, it is easy to shake, which leads to the instability of the elastic force. In the embodiment, the elastic connecting sections 322 at both sides are connected to the base respectively, and are limited at both sides of the elastic protruding section 321, so that the loosening of the elastic metal rod 32 is prevented.

[0047] Further, the cutter disc adjusting assembly further comprises a cutter disc seat 50, which can be used as an assembling base of the cutter disc 40. The cutter disc seat 50 can be mounted on the base of the coffee machine or the bean grinder.

[0048] Specifically, the first adjusting ring 10 is arranged at the bottom end of the cutter disc seat 50, and the second adjusting ring 20 is rotatably arranged on the first adjusting ring 10. The first adjusting ring 10 is provided with a connecting frame 11, which can protrude from the cutter disc seat 50. The connecting frame 11 is provided with a connecting groove 111. Correspondingly, the top end of the cutter disc seat 50 is provided with an adjusting ring 51, which is rotatably arranged on the top end of the cutter disc seat 50. The adjusting ring 51 is provided with a connecting arm 511, which is inserted into the connecting groove 111. The connecting arm 511 is used to drive the connecting frame 11 to rotate when the adjusting ring 51 rotates, so as to drive the first adjusting ring 10 to rotate.

[0049] Based on the above structure, when the distance between the cutter discs 40 is adjusted, the adjusting ring 51 at the top end of the cutter disc seat 50 can be rotated. Since the adjusting ring 51 is connected to the connecting frame 11 of the first adjusting ring 10 through the connecting arm 511, the rotation of the adjusting ring 51 can drive the first adjusting ring 10 to rotate, and further drive the second adjusting ring 20 to move up and down.

[0050] It should be noted that since the cutter disc seat 50 is used for mounting the cutter disc 40 structure, the cutter disc 40 is usually arranged inside the coffee machine or the bean grinder, and the top end of the cutter disc seat 50 is used for connecting with the bean bin structure for storing coffee beans. Therefore, the adjusting ring 51 structure arranged at the top end of the cutter disc seat 50 can be exposed, that is, the adjusting structure for adjusting the gap between the cutter discs 40 is exposed, which is convenient for operation.

[0051] More specifically, the second adjusting ring 20 is rotatably arranged on the cutter disc seat 50 and can slide along the axial direction. The second adjusting ring 20 is sleeved outside the first adjusting ring 10, so that the second guide part 22 is movably connected with the first guide part 12. Based on this structure, the rotation stopping part of the second adjusting ring 20 can be arranged outside the second adjusting ring 20, and the second guide part 22 is arranged inside the second adjusting ring 20. The second adjusting ring 20 is arranged outside the first adjusting ring 10, and the first guide part 12 of the first adjusting ring 10 is movably arranged.

[0052] Specifically, the cutter disc seat 50 is provided with a rotation stopping opening 52, and the rotation stopping part of the second adjusting ring 20 can be arranged at the position of the rotation stopping opening 52 of the cutter disc seat 50. In this way, the rotation stopping part can extend into the rotation stopping opening 52 to be connected with the rotation stopping part. That is, the rotation stopping part structure is arranged outside the cutter disc seat 50, which is convenient for disassembly and assembly. In addition, the rotation stopping part is not arranged inside the cutter disc seat 50, so as not to interfere with other structures inside the cutter disc seat 50.

[0053] Of course, if the first adjusting ring is assembled outside the second adjusting ring during assembly, the first guide part of the first adjusting ring can be arranged inside the first adjusting ring, and the second guide part of the second adjusting ring can be arranged outside the second adjusting ring, on the basis of the structure, the rotation-stopping part of the second adjusting ring can be separately arranged as a rotation-stopping ring, which is distributed with the second guide part of the second adjusting ring in the axial direction, and the rotation-stopping part of the rotation-stopping ring can correspond to the rotation-stopping opening. In addition, if the rotation-stopping opening is not arranged, the rotation-stopping part can be assembled inside the cutter holder through the elastic part.

[0054] Further, since the adjusting ring 51 is used to drive the first adjusting ring 10 to rotate, the adjusting ring 51 is connected and matched with the connecting arm 511 and the connecting frame 11 to realize linkage, in order to prevent relative rotation of the two after insertion, a limiting tooth groove 112 can be arranged in the connecting groove 111, and a limiting tooth is arranged on the connecting arm 511, and after the connecting arm 511 is assembled into the connecting groove 111, the limiting tooth is engaged with the tooth groove, so that when the connecting arm 511 drives the connecting frame 11 to rotate, the limiting tooth and the tooth groove are limited and matched, so that relative rotation of the two is reduced, and the linkage structure between the adjusting ring 51 and the first adjusting ring 10 is more stable.
