Knife sharpening mechanism

Abstract

The invention discloses a knife sharpening mechanism comprising a knife sharpening mechanism body, a polishing mechanism and an electric power control system. A clamping device, a horizontal X-axis driving rail, a driving wheel, a horizontal Y-axis driving rail, a base, a driving wheel rail, a polishing mechanism, a pressure sensor, a motor mounting bracket, a lifting bracket, a grinding wheel motor, a coarse grinding wheel, a horizontal movement guide rail and a fine grinding wheel are arranged on the knife sharpening mechanism body; the electric control system is arranged inside the knife sharpening mechanism body; and an intelligent control chip, a single chip microcomputer, a main control circuit, a photosensitive module, a time setting module, a frequency control module, a driving circuit and a pressure sensing module are arranged on the electric power control system. The knife sharpening mechanism is reasonable in design, simple in structure, small in occupied space, and good in knife sharpening effect; and the pressure between a detection grinding wheel and a blade is detected through the pressure sensing module, wear of the blade is reduced, and a knife can be sharpened quickly in the condition of small knife piece wear.

Description

technical field [0001] The invention relates to the technical field of mechanical knife sharpening, in particular to a knife sharpening mechanism. Background technique [0002] In daily life, knives are indispensable to people’s lives. Whether it is cutting vegetables, meat, etc., they are inseparable from knives. Knives will become blunt after a long time and need to be polished. The existing household grinding Knives are mostly used in the kitchen. Most of them are electric and have a complicated structure. They can only work after being powered on. It is more common in the meat market. Before the meat is cut, the butcher will grind it several times on two different grindstones. One is rough grinding, and then it is finely ground. Grinding, now there are both coarse and fine grinding stones on the same grinding stone, but when manually grinding, the distinction is not accurate, which inevitably makes the tool grinding uneven, affecting the grinding accuracy and the servic...
