Document Type and Number:
WIPO Patent Application WO/2022/228199
Kind Code:
A1
Abstract:
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.
