Description
Technical field
The present invention relates to a kind of knife sharpener, particularly relate to and a kind of be applicable to the various cutter of polishing, and cutter is ground sharper automatic knife grinder.
Background technology
Traditional sharpening mode generally divides two kinds, and the first is manually whet a knife, although can control the speed of whetting a knife as required, and can adjust angle and the direction of sharpening in time, with high content of technology, experience accumulation is difficult, and labour intensity is large, wastes time and energy.The second is automatic grinding, and it drives emery wheel to rotate by motor, makes the edge of a knife of cutter press close to emery wheel, the blade of emery wheel milling cutter in the process of high-speed rotation.Although this mode is automatic, time saving and energy saving, because the rotating speed of emery wheel is too fast, the particle on the surface of emery wheel is thin not, further, between emery wheel and cutter angle and pressure uncontrollable, therefore, can not grind more smooth cutting edge, blade there will be the shape of tooth of crouching, still sharp not after sharpening.If adopt the knife sharpener of biography rate to coordinate the thinner emery wheel of particle to whet a knife, because traditional motor output speeds is higher, the thinner emery wheel of particle when whetting a knife and cutter press close to not easy heat radiation, the easy phenomenon that burning cutter occurs, after burning cutter generation, the hardness of cutter can cannot repeatedly use in deliquescing, therefore, sharpening effect is also bad.In addition, traditional automatic knife grinder can only grind the cutter of straight cutting edge, and can not grind the cutter of curved cutting edge, adaptability is poor.
Summary of the invention
The object of the present invention is to provide and a kind of be applicable to the various cutter of polishing, and cutter is ground sharper automatic knife grinder.
To achieve these goals, automatic knife grinder provided by the invention comprises frame, platform, the first driving mechanism, the second driving mechanism, sliding seat, optical axis, deck, oilstone and knife rest; Described knife rest clamps described cutter, makes described cutter horizontally set; Described oilstone is elongated and be longitudinally installed on described deck, described deck is fixed on described sliding seat, described sliding seat is arranged on described optical axis slidably, described optical axis is in longitudinally arranging and being upper and lowerly articulated in described platform turningly, described first driving mechanism to be arranged on described platform and to drive described sliding seat to slide, and described second driving mechanism to be arranged in described frame and to drive described platform transverse translation.
