Description

Multifunctional knife grinder

Technical Field

The utility model relates to a knife sharpening device, in particular to a multifunctional knife sharpener.

Background

After the cutter is chopped for a long time, the cutter point becomes blunt, so that the chopping quality is reduced, and the cutter point needs to be polished. The knife point of the grinding tool of the prior art still continues to be grinded by a manual method of grinding by a knife stone, and the method is clumsy, low in efficiency and high in labor intensity. Although the electric grinding wheel knife grinder is also adopted to improve the efficiency and reduce the labor intensity, for different cutters, due to various complex problems such as different cutter blade radians, angles and widths, the inclination angle of the cutter blade is often mastered inaccurately by a knife grinder operator, and the phenomena of eccentric wear and excessive wear of the cutter blade are frequently caused.

The patent application publication No. CN102233529A discloses a knife sharpening device, which comprises a sharpening table, an angle adjusting component, a fixing component for fixing a knife on the angle adjusting component, a grinding wheel and a driving component. The polishing table comprises a connecting surface and a reference surface which are vertically arranged; the angle adjusting assembly is fixed on the connecting surface and comprises an arc-shaped plate, a bearing plate for bearing a cutter, an adjusting bolt and a positioning column arranged at the position corresponding to the circle center of the arc-shaped plate. The arc plate is provided with a chute penetrating through the arc plate along the extending direction of the arc plate. One end of the bearing plate is arranged in the arc-shaped plate chute in a sliding way through the adjusting bolt, and the other end of the bearing plate is provided with a through hole which is movably arranged on the positioning column. The grinding wheel is movably arranged at a position adjacent to the reference surface and used for polishing the knife edge. The driving assembly is used for driving the grinding wheel to rotate and polish the blade. The angle adjusting component of the knife sharpening device rotates the knife on the sharpening table, and the knife edge and the reference surface can be located on the same plane by adjusting the adjusting bolt, so that the knife sharpening device can sharpen the knife with different knife edge inclination angles. The knife sharpening device can not move relative to the axial direction due to the fact that the bearing plate and the driving assembly can not move relative to the axial direction, so that a sharpened knife can only be a straight knife point, and cannot work on a knife point with radian.

At present, no ideal special equipment for solving the problem of polishing the knife-edge cutter with radian exists in the market.
