A grinding apparatus, comprising: a lower grinding cutter (100), a main body frame (200), a driving electric motor (300), an upper grinding cutter (400), an adjustment structure (500), an angle sensor (600), an adjustment button (700) and a control unit, wherein the driving electric motor (300) is electrically connected to the control unit, and an output shaft of the driving electric motor (300) is in power connection with the lower grinding cutter (100); the upper grinding cutter (400) is cooperatively mounted with the lower grinding cutter (100); the adjustment button (700) is cooperatively mounted with the adjustment structure (500) for rotating the adjustment structure (500) to a target rotation angle; the adjustment structure (500) is rotatably mounted on the main body frame (200) and is sleeved outside the upper grinding cutter (400) for limiting the rotation of the upper grinding cutter (400) and adjusting a matching gap between the upper grinding cutter (400) and the lower grinding cutter (100); the angle sensor (600) is cooperatively mounted with the adjustment structure (500) for sending a sensed rotation angle to the control unit by means of signals; and the control unit determines the target rotation angle according to the rotation angle, determines a target duration corresponding to the target rotation angle according to a preset correspondence relationship between the rotation angle and the duration, and controls the grinding duration of the lower grinding cutter (100) driven by the driving electric motor (300) according to the target duration. The grinding apparatus can automatically output grinding powder with a certain weight and a certain fineness grade each time.

Abrégé

A grinding device, which can automatically output a ground powder (such as coffee powder) of a certain weight and degree of coarseness every time. In the grinding device, a driving electric motor (300) is electrically connected to a control unit. An output shaft of the driving electric motor (300) is dynamically connected to lower grinding blades (100). Upper grinding blades (400) are cooperatively mounted with the lower grinding blades (100). An output shaft of an adjusting electric motor (700) is cooperatively mounted with an adjusting structure (500), and the adjusting electric motor (700) is electrically connected to the control unit. The adjusting structure (500) is rotatably mounted on a body frame (200), is sleeved outside the upper grinding blades (400), and is used to limit the rotation of the upper grinding blades (400) and adjust a cooperative gap between the upper grinding blades (400) and the lower grinding blades (100). An angle sensor (600) is used to send a sensed rotation angle to the control unit by means of a signal. The control unit is used to control the rotation of the adjusting electric motor (700) and drive the adjusting structure (500) to achieve a set target rotation angle. The target duration corresponding to the target rotation angle is determined according to a preset correspondence between the rotation angle and a duration, thereby controlling the duration in which the grinding blades (100) are driven by the driving electric motor (300).

Abrégé

A bean grinder, comprising: a bean grinding blade assembly (1) and a plurality of bean bins (2), the bean grinding blade assembly (1) is arranged at the bottom of the bean bins (2), the bottom of each bean bin (2) is provided with a bean feeding screw, when coffee beans in a certain bean bin (2) need to be ground, the corresponding bean feeding screw rotates to convey the beans to the bean grinding blade assembly (1), when a certain proportion of coffee powder is needed, the feeding amount can be determined by rotating the number of rotations of the bean feeding screw, after the bean feeding is finished, the bean grinding blade assembly (1) should be further operated for a period of time to ensure that the coffee beans in the bean grinding blade assembly (1) are completely ground up and emptied, so as to facilitate the bean grinding operation next time. By means of the combination of different bean bins (2) and the bean feeding screws, not only different coffee beans can be conveyed and ground, but also the grinding operation of coffee beans in different proportions can be realized, in addition, advantages of being simple in structure and low in product production cost are further provided.
