[0025] A grinding device with feedback provides a solution for achieving stable grinding and output of coffee beans or other materials to be ground, and its structure includes: a grinding drive motor feedback device 1, a grinding drive motor 2, a coupling 3, a grinding wheel fixing part 4, a grinding wheel concentric bearing 5, a grinding wheel supporting bearing 6, a grinding active wheel 7, a grinding adjustment wheel (idle wheel) 8, a grinding container 9, a container dust-proof component (static electricity pressing component) 10, a powder output guide component 11, and a grinding gear fixing / adjusting device 12.

[0026] The bottom of the grinding driving wheel is connected to the grinding container through a grinding wheel supporting bearing, so that the grinding driving wheel can be rotatably set in the grinding container, and the lower part of the moving wheel transmission shaft 71 located at the center of the grinding driving wheel is movably connected to the grinding container through a grinding moving wheel fixing piece and a grinding moving wheel concentric bearing. The centering of the grinding driving wheel is improved by an independent concentric bearing, and the flatness of the grinding driving wheel is optimized by an independent planar thrust bearing (grinding wheel supporting bearing) to improve the stability of grinding.

[0027] The grinding drive motor is connected to the lower end of the driving wheel transmission shaft through a coupling to drive the grinding driving wheel to rotate and grind in the grinding container. The output shaft of the grinding drive motor and / or the grinding driving wheel are provided with a sensor 21 that cooperates with the feedback device. The sensor can also be the output shaft itself, the grinding driving wheel or the driving wheel 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.

[0028] Further preferably, the grinding drive motor feedback device includes a grating feedback device, a position feedback device, etc. During the grinding process, the output shaft of the grinding drive motor and / or the grinding driving wheel are detected by the grinding drive motor feedback device to collect the operating conditions of the grinding device in real time, such as the running time / speed / stroke (number of turns & angle), etc.

[0029] A plurality of powder pushing parts 72 are evenly distributed on the outer circumference of the grinding driving 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 91 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 of the material. Among them, the static electricity-removing powder pressure part can be made of SUS metal sheet, which will pre-press the powder and at the same time guide the powder box to remove static electricity.

[0030] The grinding adjustment wheel is arranged above the grinding driving wheel and is movably connected to the grinding container. The grinding gear fixing / adjusting device 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.

When the adjustment gear is driven to rotate by rotating the adjustment rod 122 in the grinding gear fixing / adjusting device, the adjustment gear synchronously drives the grinding adjustment wheel to rotate to adjust the degree of connection between the grinding adjustment wheel and the grinding container, thereby achieving adjustment of the upper and lower position (height) of the grinding adjustment wheel.

[0034] The grinding driving wheel is fixed in the grinding container in the center and horizontally through the grinding wheel fixing part, grinding wheel concentric bearing and grinding wheel support bearing, ensuring the stability of the movement process; the grinding adjustment wheel cooperates with the grinding gear fixing / adjusting device to adjust and control the grinding gear. When in use, the grinding driving motor drives the coupling and the grinding driving wheel, so that the grinding driving 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.

[0035] The beneficial effects of the grinding device with feedback of the utility model are: the stability of the grinding device and the system feedback direction are improved, the structure is stable, the feedback is direct and efficient, and more stable grinding products and more timely and accurate status monitoring of coffee machines, bean grinders and other equipment with grinding requirements are achieved.
