Abstract

The utility model relates to a knife sharpener, particularly a knife sharpener for sharpening kitchen knives suitable for families, restaurants, and dining rooms. Primarily, a housing is provided with a knife slotting frame with a radial locating narrow groove. A motor set is fixed on an inner wall of the housing. A pair of coarse sharpening wheels and a pair of fine sharpening wheels are respectively connected with a left and a right cantilevering shafts of the motor by endwise slip. Compression springs supported in axial direction of the left and the right cantilevering shafts are respectively abutted on both of the outer sides of the pair of coarse sharpening wheels and the pair of fine sharpening wheels. Thereby, the utility model has the advantages of assuring knife sharpening quality, shortening knife sharpening operation time, and meanwhile preventing environmental pollution.

Description

Knife sharpener

The utility model relates to a kind of knife sharpener, is particularly suited for the sharpen a kitchen knife knife sharpener of usefulness of family, restaurant and dining room.

At present, traditional method that sharpens a kitchen knife is that hand-held kitchen knife repeatedly rubs mill on whetstone, and the quality of sharpening is mainly with sharpening people's experience, and the process of grinding also can pollution clothes and environment, and in addition, sharpening efficient is extremely low.

In view of this, the purpose of this utility model provides a kind of knife sharpener, can make the location automatically of being whetted a knife, and keeps the locking device of grinding blade size.

The purpose of this utility model is achieved in that it mainly comprises casing, group of motors, corase grind wheel, fine grinding wheel and several compression springs, wherein casing is provided with the slotting tool frame of the narrow groove of band radial location, group of motors is to connect a left cantilevered axle and a right cantilevered axle respectively at the axle two ends of a motor, this group of motors is fixed on the casing inner wall, a pair of corase grind wheel and a pair of fine grinding wheel be connected axially slidably respectively left and right cantilevered axle, on, again be supported in left and right cantilevered axle, axial compression spring is taken turns the 3 liang of outsides and a pair of fine grinding wheel two outsides against a pair of corase grind respectively.

The cylinder wheel that above-mentioned corase grind wheel is an end outer rim Duan Weiyi taper seat.

Above-mentioned fine grinding wheel is that an end outer rim section is the cylinder wheel of homogeneous phase convex-concave taper seat at interval.

Owing to adopt such scheme: can guarantee the quality of whetting a knife and shorten the operating time of whetting a knife, also prevent the particle contamination environment of grinding simultaneously.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1, the utility model exemplary embodiments schematic diagram;

Fig. 2, the utility model exemplary embodiments fine grinding wheel cross-sectional schematic;

Fig. 3, the horizontal schematic diagram of the utility model exemplary embodiments fine grinding wheel.

Among the figure: 1, casing 11, slotting tool frame 2, group of motors 21 left cantilevered axle 22, right cantilevered axle

3, corase grind wheel 4, fine grinding wheel 5, compression spring

Present embodiment mainly comprises casing 1, group of motors 2, a pair of corase grind wheel 3, a pair of fine grinding wheel 4 and several compression springs 5, shown in Fig. 1～3, wherein:

Casing 1 is except that both sides are respectively equipped with slotting tool frame 11, and its whole positions all are the plastics shell block of closed state, and wherein slotting tool frame 11 is the shell framves with the narrow groove of radial location, adjusting position slidably, be screwed then on casing 1, the offerings cutter inserts, and makes its blade contact emery wheel.

Group of motors 2 is to connect a left cantilevered axle 21 and a right cantilevered axle 22 respectively at the axle two ends of a motor, and this group of motors (motor and electrical equipment thereof) is fixed in the casing 1, and left and right cantilevered axle 21,22 also supports (rolling bearing is arranged) on casing 1 endoseptum.

Corase grind wheel 3 is cylinder wheels of an end outer rim Duan Weiyi taper seat, and a pair of taper seat is relative and the contacted corase grind wheel of inner segment is right; Its edge section forms V shaped sections annular groove, blade for the grinding kitchen knife, this a pair of corase grind is taken turns 3 usefulness square holes or key is engaged on the left cantilevered axle 21 and be respectively equipped with the compression spring 5 that is supported on the left cantilevered axle 21 end shoulders in the both sides of two corase grind wheels 3 respectively, all the time making two corase grind take turns 3 keeps in touch (compensating the slit that the emery wheel wearing and tearing cause automatically) and keeps certain cutting force (adjusting the axial elastic force of spring), this corase grind wheel 3 also can be formed two groups on thick, middle mill by three emery wheels, and an only middle emery wheel two ends outer rim section is all the cylinder wheel of taper seat.

Fine grinding wheel 4 is that an end outer rim section is the cylinder wheel of homogeneous phase convex-concave taper seat at interval, and a pair of convex-concave taper seat relatively, inner segment contacts and inside and outsidely intersegmentally have the fine grinding wheel in space right; The blade of grinding kitchen knife is not limited by the depth, can guarantee the sharpening quality, this a pair of fine grinding wheel 4 usefulness square holes or key is engaged on the right cantilevered axle 22 and be respectively equipped with the compression spring 5 that is supported on the right cantilevered axle 22 axle head shoulders in the both sides of two fine grinding wheels 4 respectively, two fine grinding wheels 4 are kept in touch and keep certain cutting force, shown in Fig. 2,3.
