The centering of the grinding wheel is improved by an independent concentric bearing, and the flatness of the grinding wheel is optimized by an independent planar supporting bearing to improve the stability of grinding.

[0028] A plurality of powder pushing parts A72 are evenly distributed on the outer circumference of the grinding wheel to effectively output the grinding powder and prevent the occurrence of abnormalities such as powder blockage. The powder outlet guide part is connected to the powder outlet A91 on the side wall of the grinding container, and a static electricity-removing powder pressure part is provided at the inner end of the powder outlet guide part and / or the upper part of the powder outlet, which can effectively prevent the powder from being scattered and flying, so as to facilitate the discharge. The static electricity-removing powder pressure part can be made of SUS metal sheet, which will pre-press the powder and guide out the static electricity by connecting with the powder box.

[0029] The grinding adjustment wheel is arranged above the grinding wheel and is threadedly connected to the grinding container. The grinding degree adjustment mechanism is connected to the grinding adjustment wheel to adjust the upper and lower positions of the grinding adjustment wheel on the grinding container to meet different grinding requirements. The upper part of the grinding wheel and the lower part of the grinding adjustment wheel are relatively provided with mutually matching grinding knives A12, wherein the grinding knives can be connected by fasteners such as bolts, plug-in or clamping.

[0030] The grinding drive motor is connected to the lower end of the transmission shaft through a coupling to drive the grinding wheel to rotate and grind in the grinding container. The output shaft and / or the grinding wheel of the grinding drive motor are provided with a sensor A21 that matches the grinding drive feedback device. The sensor can also be the output shaft itself, the grinding wheel or the transmission shaft itself. By monitoring the grinding (motor) state, the state of grinding execution can be monitored more directly and accurately, and the operating status of the grinding system can be identified in combination with the feedback information, so as to manage and control the operating status of the grinding system more accurately and efficiently.

[0031] Further preferably, the grinding adjustment feedback ring and the grinding drive feedback include a grating feedback, a position feedback, etc. During the grinding process, the output shaft of the grinding drive motor and / or the grinding wheel are detected by the grinding drive feedback to collect the operating conditions of the grinding device in real time, such as the running time / speed / stroke (number of turns & angle), etc.

[0032] Further preferably, the grinding adjustment wheel is provided with a feed port connected to the grinding container.

[0033] The grinding wheel is fixed in the grinding container in the center and horizontally through the grinding wheel fixing part, grinding wheel concentric bearing and supporting bearing, ensuring the stability of the movement process; the grinding adjustment wheel cooperates with the grinding degree adjustment mechanism to adjust and control the grinding gear. When in use, the grinding drive motor drives the coupling and the grinding wheel, so that the grinding wheel and the grinding adjustment wheel move relative to each other to grind coffee beans or other materials to be ground into powder, and the powder is discharged to the powder outlet and powder guide part of the grinding container through the powder pushing part; the discharge process is discharged after the static electricity of the powder is removed by the anti-static powder pressing part and the powder is compacted.

[0034] The grinding degree adjustment mechanism B can realize grinding degree adjustment during use and feedback the operating status of the grinding degree adjustment component. Its structure includes a grinding adjustment motor B1, a grinding adjustment feedback device B2, an adjustment motor fixing seat B3, an auxiliary fixing part B4, and a high-pair transmission part.

[0035] The adjusting motor fixing seat is movably connected to the grinding container, the high-pair transmission member is rotatably connected to the auxiliary fixing member on the adjusting motor fixing seat, the grinding adjusting motor is arranged on the adjusting motor fixing seat, and its output end is connected to the high-pair transmission member to drive it to rotate, and the grinding adjusting feedback device is connected to the output shaft / high-pair transmission member of the grinding adjusting motor to monitor and feedback the status of the motor / high-pair transmission member, such as running time / speed / stroke (number of turns & angle), etc.

[0036] Further preferably, the adjusting motor fixing seat is assembled on the grinding container along the vertical direction through an elastic buckle B31.

[0039] When in use, insert the guide rib B32 on the adjusting motor fixing seat into the guide groove B33 on the grinding container, and press the adjusting motor fixing seat down in the vertical direction until the female buckle B311 of the elastic buckle on the adjusting motor fixing seat is engaged with the male buckle B312 on the grinding container, thereby completing the installation of the motor fixing seat. At this time, the thread on the worm B5 is engaged with the gear ring A81 on the outer periphery of the grinding adjustment wheel. When the grinding adjustment motor drives the worm forward / reverse to rotate on the adjusting motor fixing seat, the worm synchronously drives the grinding adjustment wheel to rotate to adjust the connection degree between the grinding adjustment wheel and the grinding container, that is, the adjustment of the upper and lower positions (height) of the grinding adjustment wheel, thereby achieving the adjustment of the grinding coarseness (the smaller the distance between the grinding wheel and the grinding adjustment wheel, the finer the grinding). At the same time, when performing grinding adjustment, the grinding adjustment feedback device detects the changing state of the adjustment mechanism in real time and provides feedback to achieve precise control and timely error reporting or triggering countermeasures when abnormal.
