Full-automatic knife sharpener

Abstract

The invention discloses a full-automatic knife sharpener. The full-automatic knife sharpener comprises an outer shell and a sliding frame; two knife sharpening assemblies are arranged in the sliding frame; each knife sharpening assembly comprises a knife sharpening pipe and a knife sharpening gear; the sharpening pipes in the two sharpening assemblies are arranged in a crossed mode; a driving motor is fixedly connected in the outer shell; two climbing assemblies are arranged in the sliding frame; each climbing assembly comprises climbing wheels; the peripheries of the climbing wheels abut against the inner wall of the outer shell; a pressing assembly is arranged in the outer shell; and the pressing assembly comprises a rhombic telescopic frame, a pressing block and a pressing motor. When the knife sharpening gear rotates, the sliding frame slides longitudinally, and meanwhile the knife sharpening pipe is driven to rotate in the circumferential direction. The full-automatic knife sharpener can automatically and uniformly grind the knife; various types of knives can be ground, and higher compatibility is achieved; a plurality of sharpening blocks with different purposes are arranged; and automatic operation is mostly adopted, excessive manual participation is not needed, and time and labor are saved.

Problems solved by technology

[0003] When the above-mentioned patent is in use, the user needs to press the cutting edge against the sharpening wheel, and the friction between the sharpening wheel and the cutting edge makes the knife have a certain movement tendency, thereby increasing the strength of holding the knife, which is very inconvenient. It is also difficult to control the pressing force between the cutting edge and the grinding wheel, so that the grinding of the cutting edge is uneven, which may easily cause the cutting edge to break and cause damage to the knife. The above-mentioned patents cannot meet the needs of use to a certain extent.
