Description

Technical Field

[0001] The utility model relates to the technical field of flavor grinders, in particular to an electric flavor grinder. Background Art

[0002] Existing manual grinders need to be operated with both hands, which is inconvenient. For dry battery grinders, the batteries need to be frequently replaced during use.

[0003] Working Principle:

[0004] It is controlled by a stepless speed regulation system, and the grinding speed suitable for grinding various parts can be easily adjusted. The electro-pneumatic proportional valve closed-loop feedback pressure control is adopted to independently control the pressure device. The upper plate is provided with a slow descent function, effectively preventing the breakage of brittle workpieces. Through a time relay and a grinding counter, the grinding time and the number of grinding circles can be accurately set and controlled according to the processing requirements. The pressure mode can be adjusted during work. When the set grinding time or the number of grinding circles per speed is reached, it will automatically stop and give an alarm prompt, realizing semi-automatic operation.

[0005] A grinding machine speed control method. The grinding process has three stages, namely the starting stage, the formal stage and the ending stage. In the starting stage, the grinding tool rotates at an increasing speed, in the formal stage, the grinding tool rotates at a constant speed, and in the ending stage, the grinding tool rotates at a decreasing speed. It is characterized in that, in the starting stage of the grinding process, the acceleration of the grinding tool speed is artificially controlled to increase from zero slowly to quickly. When the grinding tool speed rises to half of the formal grinding speed, there is an inflection point in the change of the acceleration. The acceleration of the grinding tool speed is controlled to decrease from the maximum value quickly to slowly until the grinding tool speed reaches the formal grinding speed, and the acceleration of the grinding tool speed drops to zero.

[0006] Utilizing this characteristic of fixed abrasive grinding, according to the relative motion trajectory density distribution between the workpiece and the grinding tool, the abrasive density distribution on the grinding tool is reasonably designed, so that the wear of the grinding tool during the grinding process does not affect the surface profile accuracy of the grinding tool, thereby significantly improving the surface profile accuracy of the workpiece and avoiding the trouble of dressing the grinding tool. In planar fixed abrasive grinding, the rotational motion of the grinding tool is the main motion, and the motion of the workpiece is the auxiliary motion. In most cases, the workpiece is floatingly pressed on the grinding tool, and its motion law is unknown. Therefore, it is necessary to analyze the force on the workpiece to obtain its force state and motion law. Taking the workpiece as the separated body of the entire grinding system, establishing the differential equation of the workpiece force balance, and solving this equation can obtain the motion law of the workpiece.

[0007] The comparative document (publication number: CN201922228138.8) discloses a ceramic seasoning grinder, which includes a bottle body, a grinding unit, a feeding unit and positioning holes. Bottle body: Positioning holes are provided at both the front and rear ends on the outer side of the bottle body, and a feeding unit is provided inside the bottle body. Grinding unit: The grinding unit includes a turntable, grinding lines, a thickness adjustment block, a ceramic grinding head, a screw rod, a return spring and a mounting rod. The right end of the turntable is rotatably connected to the left side surface of the bottle body. A circular groove is provided inside the turntable, and grinding lines are arrayed on the inner side of the circular groove. The mounting rod is arranged in the mounting groove in the middle of the left side surface of the bottle body. The middle of the left side surface of the mounting rod is connected to the right end of the screw rod. The screw rod is located inside the circular groove of the turntable and is threadedly connected to the screw hole in the middle of the ceramic grinding head. The screw hole on the side of the thickness adjustment block is threadedly connected to the screw rod and is located on the left side of the ceramic grinding head. This ceramic seasoning grinder is simple to use, has a good grinding effect, and is convenient for replacing seasonings.
