Automatic knife sharpener

Abstract

The invention discloses an automatic knife sharpener. The automatic knife sharpener comprises a frame, a platform, a first driving mechanism,a second driving mechanism, a slide base, an optical shaft, a clamping base, an oil stone and a knife post, wherein the knife post clamps a cutter, so that the cutter is transversely placed; the oil stone is strip-shaped, and is longitudinally arranged on the clamping base; the clamping base is fixed on the slide base; the slide base is slidingly arranged on the optical shaft; the optical shaft is longitudinally arranged, and is pivoted to the platform in an up-down turnover manner; the first driving mechanism is arranged on the platform, and drives the slide base to slide; and the second driving mechanism is arranged on the frame, and drives the platform to perform transverse translation. The automatic knife sharpener is suitable for polishing various cutters, and can enable the cutters to become sharper.

Description

technical field [0001] The invention relates to a knife sharpening machine, in particular to an automatic knife sharpening machine suitable for grinding various knives and making the knives sharper. Background technique [0002] There are generally two types of traditional knife sharpening methods. The first is manual knife sharpening. Although the speed of sharpening can be controlled according to needs, and the angle and direction of sharpening can be adjusted in time, but the technical content is high, and experience accumulation is difficult. Intensive, time-consuming and labor-intensive. The second is automatic knife sharpening, which drives the grinding wheel to rotate through the motor, so that the edge of the knife is close to the grinding wheel, and the grinding wheel grinds the cutting edge of the tool during high-speed rotation. Although this method is automatic and saves time and effort, the grains on the surface of the grinding wheel are not fine enough because...

Problems solved by technology

Although this method is automatic and saves time and effort, the grains on the surface of the grinding wheel are not fine enough because the speed of the grinding wheel is too fast, and the angle and pressure between the grinding wheel and the tool cannot be controlled, so a smoother edge cannot be ground. The edge of the knife will appear in the shape of teeth, and it is still not sharp enough after sharpening

If a high-speed knife grinder is used to sharpen the knife with a finer-grained grinding wheel, due to the high output speed of the traditional motor, the finer-grained grinding wheel is not easy to dissipate heat when it is close to the knife, and it is easy to burn the knife. After the knife is broken, the hardness of the knife will become soft and cannot be used many times, so the sharpening effect is not good

In addition, traditional automatic sharpeners can only sharpen knives with straight edges, but cannot sharpen knives with curved edges, which has poor adaptability
