Electric knife sharpener

Abstract

The invention discloses an electric knife sharpener. The electric knife sharpener comprises a rack, a drive motor, a knife rest and a knife sharpening stone device, wherein the knife rest is connected to a base; a first screw rod and a second screw rod which are provided with reciprocating spiral grooves are rotationally supported on the rack respectively, a first slide sleeve and a second slide sleeve are installed on the first screw rod and the second screw rod respectively in a sleeving manner, a first pin shaft which is in slide fit in the reciprocating spiral groove of the first screw rod is fixedly connected to the first slide sleeve, and the first slide sleeve is fixedly connected to the base of the knife rest; a second slide sleeve is installed on the second rod in a sleeving manner, a second pin shaft which is in slide fit in the reciprocating spiral groove of the second screw rod is fixedly connected to the second slide sleeve, and the second slide sleeve is fixedly connected to the knife sharpening stone device; the drive motor is controlled by a control system and used for driving the first screw rod and the second screw rod to rotate according to set directions respectively by virtue of a transmission box with rotary power output. The electric knife sharpener disclosed by the invention has the beneficial effects of simple structure, low manufacturing cost, convenient installation and debugging, and few fault hidden dangers.

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...

AI Technical Summary

Problems solved by technology

The transmission structure of the movement of the knife holder and the movement of the whetstone is complicated, and there are deficiencies in manufacturing difficulties and many hidden troubles

In addition, the whetstone is equipped with a strip-shaped whetstone installation part that automatically compensates for the height of the whetstone. The height of the whetstone is automatically compensated to maintain the sharpening pressure of the knife and ensure the efficiency and effect of sharpening. However, the bar-shaped whetstone installation part also has a defect of complex structure
