An electric sharpener

Abstract

The invention discloses an electric knife sharpener which comprises a knife rest and a knife stone device. The knife stone device comprises a height compensation mechanism and a mounting base supporting device. The mounting base supporting device comprises isosceles-trapezoid wedge blocks arranged at the two ends of a knife stone mounting base in a 180-degree inverted mode. Multiple rotatable supporting arms are arranged at the positions, located outside the two ends of the knife stone mounting base, on a sharpener base and are symmetrically distributed along the outer sides of the two edges of the isosceles-trapezoid wedge blocks, and the multiple rotatable supporting arms on any side are distributed in the vertical direction. The rotating axle center of each rotatable supporting arm is located at the lower end of the rotatable supporting arm. When the knife stone mounting base is located at any height position in the lifting range, the isosceles-trapezoid wedge blocks form an arch supporting structure through the at least one rotatable supporting arm on each edge. The knife rest and the knife stone device are driven through longitudinal circulation moving chain links and circulation moving chain links respectively and carry out back and forth movement in the longitudinal direction and the transverse direction respectively. The electric knife sharpener has the advantages that the height of a knife stone can be compensated, the knife stone is supported stably, and the whole electric knife sharpener is compact in structure and low in fault rate.

Description

technical field [0001] The patent of the present invention relates to a knife sharpener, in particular to an electric knife sharpener for grinding kitchen knives. Background technique [0002] The main variety of kitchen knives is kitchen knives. There are usually two grinding methods for existing kitchen knives. One is to use a whetstone and the sharpener directly moves the knife on the whetstone by hand. This grinding method is inefficient, labor-intensive, and the grinding quality Unevenness, that is, the sharpness of the tool after grinding, the service life after grinding once, and the loss of the tool per grinding are all affected by the skill level of the sharpener. The second is to use a knife grinder composed of a rotating grinding wheel for grinding, and its tool feeding method includes manual feeding of a manual hand-held tool and mechanical feeding by a feeding mechanism. However, existing knife sharpeners all use rotating emery wheels as grinding tools for kni...
