[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] See also Figure 1-Figure 4 A blade disc adjustment structure of a bean grinder, comprising a bean grinding container 10, wherein a bean grinding chamber 110 with an upper opening is arranged in the bean grinding container 10, a lower blade disc element 30 is arranged in the bean grinding chamber 110, an upper blade disc assembly 20 is arranged above the lower blade disc element 30, an adjustment element 40 is rotatably arranged on the bean grinding container 10, a driven groove 410 with an upper opening is arranged on the adjustment element 40, a driven block 250 is arranged on the upper blade disc assembly 20, and the driven block 250 is movably inserted in the driven groove 410, an adjustment track groove 120 is arranged on the inner wall of the bean grinding chamber 110, the adjustment track groove 120 is gradually inclined downward from one end to the other end, and one end of the adjustment track groove 120 is opened to form an opening 130, and a track element 200 is arranged on the upper blade disc assembly 20, and the track element 200 can pass through the opening 130 and be screwed into the adjustment track groove 120;

[0024] When the adjusting element 40 rotates radially, it pushes the driven block 250 through the driven groove 410 to drive the upper cutter head assembly 20 and the adjusting element 40 to rotate radially in the same direction;

[0025] The driven block 250 can move relative to the driven slot 410 along the axial direction of the upper cutter disc assembly 20, and the two can move relative to each other along the axial direction of the upper cutter disc assembly 20, so that the adjusting element 40 will not affect the upper cutter disc assembly 20 when axial movement occurs.

[0026] The adjusting element of the utility model is rotatably arranged on the bean grinding container, and through the cooperation of the driven groove and the driven block, the adjusting element and the upper blade disc assembly can be moved synchronously, so that when disassembling, it is only necessary to rotate the upper blade disc assembly to screw the track element into the opening of the adjusting track groove, and then the upper blade disc assembly can be taken up. Compared with the prior art, there is no need to disassemble the adjusting element, which avoids the workload caused by repeated disassembly and assembly of the tooth-engaging elements, optimizes the disassembly and assembly process, and improves efficiency.

[0027] In the present invention, the adjusting element 40 is rotatably provided on the bean grinding container 10, so that there is a gap in the assembly relationship between the adjusting element 40 and the bean grinding container 10. At the same time, the upper blade disc assembly 20 is assembled in the adjusting track groove 120 through the track element 200, so that there is a gap in the assembly relationship between the upper blade disc assembly 20 and the bean grinding container 10. The gap between the upper blade disc assembly 20 and the bean grinding container 10 will cause an error in the upper and lower adjustment process of the upper blade disc assembly 20. In the utility model, the upper blade disc assembly 20 cooperates with the track element 200 and the adjusting track groove 120, and adopts the cooperation between the driven block 250 and the driven groove 410. The adjusting element 40 will not constrain the longitudinal movement of the upper blade disc assembly 20, so that when the upper blade disc assembly 20 is longitudinally adjusted, it is only constrained by the cooperation between the track element 200 and the adjusting track groove 120, so that the upper blade disc assembly 20 will only be affected by the matching clearance between the track element 200 and the adjusting track groove 120, so that the upper blade disc assembly 20 will not be affected by the clearance between the adjusting element 40 and the grinding container 10, so as to avoid the existence of two or more clearances. The reduction of the clearance can effectively reduce the distance error between the upper blade disc assembly 20 and the lower blade disc element 30, so as to effectively ensure the stability of the upper blade disc assembly 20.

[0028] See also Figure 3 The adjusting element 40 is provided with a clearance groove 420 corresponding to the track element 200. The clearance groove 420 is provided to allow the track element 200 to pass through the clearance groove 420 and enter the adjusting track groove 120.

[0029] See also Figure 3A slide rail 140 is provided on the outer wall of the bean grinding container 10, and a slider 430 is provided on the adjusting element 40. The slider 430 slidably cooperates with the slide rail 140. The cooperation between the two can effectively constrain the longitudinal position of the upper blade disc assembly 20 to prevent the upper blade disc assembly 20 from moving upward or downward.

[0030] Furthermore, the slide rail 140 is a convex rib, and the slider 430 is L-shaped. The slider 430 is screwed into the bottom of the slide rail 140 from one end of the slide rail 140, and is hooked on the lower end surface of the slide rail 140 through the L-shaped slider 430 to achieve position constraint.

[0031] See also Figure 3 The grinding container 10 is provided with an ear seat 610, and the ear seat 610 is provided with an adjustment shaft 600 that can rotate relative to the ear seat 610 and move up and down. The adjustment shaft 600 on the upper and lower sides of the ear seat 610 is respectively provided with a driving gear 650 and a locking gear 630, and the driving gear 650 is drivingly connected to the adjustment element 40;

[0032] The ear seat 610 is provided with a gear rack 611 meshing with the locking gear 630 , and a spring 640 is provided on the adjustment shaft 600 between the driving gear 650 and the ear seat 610 .

[0033] Under normal conditions, the driving gear 650 is in transmission connection with the adjusting element 40, and the locking gear 630 and the gear frame 611 are meshed with each other to achieve locking of the adjusting element 40. When unlocking is required, the adjusting shaft 600 is pressed to move the adjusting shaft 600 downward, so that the locking gear 630 is separated from the gear frame 611, and then the adjusting shaft 600 is rotated, so that the adjusting shaft 600 drives the driving gear 650 to drive the adjusting element 40 to rotate, thereby driving the upper cutter head assembly 20 to rotate, and under the action of the adjusting track groove 120, the longitudinal position adjustment of the upper cutter head assembly 20 can be achieved.

[0034] The function of the spring 640 is to apply a force to the driving gear 650 so that the locking gear 630 can maintain meshing with the gear frame 611 .

[0035] See also Figure 3 The adjusting shaft 600 is provided with a rotating knob 660 .

[0036] In the present invention, the adjusting element 40 is a ring gear, and the driving gear 650 and the adjusting element 40 are meshed with each other.

[0037] See also Figure 2The upper cutter disc assembly 20 includes an adjusting knob 210 and an upper cutter disc element 220 fixedly disposed below the adjusting knob 210 , and the follower block 250 and the track element 200 are fixedly disposed on the outer wall of the adjusting knob 210 .

[0038] See also Figure 2 A sealing ring 230 is provided between the upper cutter disc element 220 and the adjusting knob 210 , and the upper cutter disc element 220 is fixedly connected to the adjusting knob 210 by a plurality of bolts 240 .
