The lower end of the adjusting ring 21 is provided with a coarse gear ring 213 and a fine gear ring 214; the lower cutter assembly 30 includes a lower cutter seat 31 for mounting the lower cutter 33, the upper end of the lower cutter seat 31 is provided with a guide block 34, and the upper cutter seat 11 is provided with a guide groove 14 that cooperates with the guide block 34 to guide the upper cutter seat 11 in the up and down movement direction; the adjusting assembly 20 also includes an adjusting rod 22, a first gear 23 engaging the coarse gear ring 213 and a second gear 24 engaging the fine gear ring 214, the adjusting rod 22 can move along its own length direction to control the rotation of the first gear 23. The first gear 23 rotates or the second gear 24 rotates; the adjusting rod 22 is provided with a first driving wheel 221 and a second driving wheel 222 spaced apart along its length. The adjusting rod 22 drives the first gear 23 to rotate through the first driving wheel 221, and drives the second gear 24 to rotate through the second driving wheel 222; a first through hole 231 is opened on the axis of the first gear 23, and a second through hole 241 is opened on the axis of the second gear 24; a first limiting groove 232 corresponding to the shape of the first driving wheel 221 is opened on the inner side wall of the first through hole 231, and the second gear 24 rotates. The inner wall of the through hole 241 is provided with a second limiting groove 242 corresponding to the shape of the second drive wheel 222; by setting a coarse gear ring 213 and a fine gear ring 214, the moving adjustment rod 22 controls the first gear 23 or the second gear 24 to rotate, thereby driving the first adjustment ring 21 to rotate at different speeds. This can achieve both rapid adjustment of the tool holder and fine adjustment of the distance between the upper tool holder 11 and the lower tool holder 31 at different speeds, thus solving the problem that the existing tool holder adjustment mechanism cannot simultaneously meet the requirements of rapid adjustment and fine adjustment of the tool holder.

[0032] The adjustment assembly 20 also includes a knob seat 41 fixedly installed on the grinding machine frame 40. The end of the adjustment rod 22 away from the first gear 23 passes through the knob seat 41. A first sleeve 42 protrudes from the knob seat 41. The first sleeve 42 has a third limiting groove 421 corresponding to the second gear 24. A knob 43 is provided on the side of the knob seat 41 away from the second drive wheel 222. The knob 43 is sleeved on the adjustment rod 22. The knob 43 can drive the adjustment rod 22 to rotate around its own length axis and move along its own length direction. By setting the third limiting groove 421, the position of the second gear 24 can be limited to avoid deviation and reduce the equipment failure rate. By setting the knob 43, it is easier to better control the rotation and movement of the adjustment rod 22.

[0033] The inner wall of the first adjusting ring 21 has a protruding ring 212, and the coarse gear ring 213 is disposed on the lower side of the protruding ring 212; the fine gear ring 214 is disposed on the lower end face of the first adjusting ring 21, and a limiting space 215 is formed between the inner wall of the first adjusting ring 21 and the coarse gear ring 213 to block the first gear 23; by setting the limiting space 215, the first gear 23 can be limited to avoid the first gear 23 from running off-center and reduce the equipment failure rate; at the same time, by setting the protruding ring 212, the minimum distance between the upper cutter 12 and the lower cutter 33 can also be controlled to avoid the upper cutter 12 and the lower cutter 33 from colliding and being damaged.

[0034] The lower blade holder 31 is provided with a second sleeve 32 protruding from its periphery. The second sleeve 32 has a fourth limiting groove 321 corresponding to the first drive wheel 221. During assembly, the first drive wheel 221 is located in the fourth limiting groove 321. By setting the fourth limiting groove 321 in conjunction with the knob seat 41, the adjusting rod 22 can be limited.

[0035] In this invention, the first drive wheel 221 is fixedly connected to the end of the adjusting rod 22 near the first gear 23. By setting the first drive wheel 221 at the end of the adjusting rod 22 near the first gear 23, the length of the adjusting rod 22 can be further shortened, thereby achieving the effect of reducing the overall size of the equipment.

[0036] The upper tool holder 11 is fitted with a second adjusting ring 13 on its outer side, and the second thread 211 is provided on the outer side wall of the second adjusting ring 13; the guide groove 14 is provided on the inner side wall of the second adjusting ring 13; by providing the second adjusting ring 13, the upper tool holder 11 can be easily disassembled, thereby improving the speed of subsequent maintenance.

[0038] In this invention, the upper knife holder 11 is also provided with a placement block for placing the handle 111; by setting the placement block, it is easier to grasp the handle 111.

[0039] In this invention, both the first gear 23 and the second gear 24 are conical. By setting the first gear 23 and the second gear 24 to be conical, the first gear 23 and the second gear 24 can more easily mesh with the coarse gear ring 213 and the fine gear ring 214 to drive the first adjusting ring 21 to rotate.

[0040] In this invention, the diameter of the first gear 23 is larger than the diameter of the second gear 24, and the number of teeth of the first gear 23 is smaller than the number of teeth of the second gear 24; by setting gears of different sizes, the moving speed of the upper tool holder 11 assembly can be better controlled.

[0041] The method of using this utility model is as follows: When using, pour coffee beans into the funnel opening of the upper knife holder 11, grasp the knob 43 and pull the adjusting rod 22 outward so that the first drive wheel 221 is inserted into the first through hole 231 and the second drive wheel 222 is disengaged from the second through hole 241. Then, rotate the knob 43 to make a coarse adjustment to the position of the upper knife holder 11. After the coarse adjustment is completed, grasp the knob 43 and push the adjusting rod 22 inward so that the second drive wheel 222 is inserted into the second through hole 241 and the first drive wheel 221 is disengaged from the first through hole 231. Then, rotate the knob 43 to make a fine adjustment to the position of the upper knife holder 11.

[0042] This invention, by setting a coarse gear ring 213 and a fine gear ring 214, and moving the adjusting rod 22 to control the rotation of the first gear 23 or the second gear 24, enables the first adjusting ring 21 to rotate at different speeds, thereby adjusting the distance between the upper tool holder 11 and the lower tool holder 31 at different speeds. This allows for both rapid and fine adjustment of the tool holder, meeting market demands and enhancing market competitiveness.
