Description

Motor-driven cutter grinder

The utility model relates to daily living article, is specifically related to a kind of electric household knife sharpener.

Existing knife sharpening device, or be to drive with manpower, be not easy to physical weak person and use, or be to adopt dc source, very uneconomical, and also sharpening efficient is not high, is difficult to be accepted by more people.

The purpose of this utility model be to provide a kind of overcome the prior art shortcoming, the electrically driven (operated) electric knife sharpener of efficient, wieldy interchange.

The purpose of this utility model is to realize like this, construct a kind of electric knife sharpener, comprise: plastic feet 19, can be contained on the described plastic feet 19, the surrounding, top is along being provided with the convex edge and center of top has the plastic casing 4 of a circular-shaped, concave cavity, the transparent plastic outer cover 1 that can cooperate with the described convex edge of described plastic casing 4, be fixed on the power transformer 14 on the described plastic feet 19, be fixed on the permanent magnet direct current motor 13 of the described circular-shaped, concave cavity bottom surface of described plastic casing 4 by screw 9, be fastened on and turn 8 on 13 on the described motor, turn 8 and the grinding carriage 7 that is slidingly installed of described motor reel by stage clip 6 with described, by resin-bonded emery wheel 5 on described grinding carriage 7, and the baffle plate 2 that is installed in described emery wheel 5 end faces.

Electric knife sharpener of the present utility model has following characteristics: 1) applicable to the grinding blade of the various cutters of family such as kitchen knife, scissors, broadsword, fruit knife etc., widely applicable, grinding speed is fast, and is time saving and energy saving; 2) be provided with multiple positioner, grinding blade unanimity, easy operating; 3) this knife sharpener uses 220V, 50HZ Alternating Current Power Supply, and power is big, and the linear velocity height is easy to use; 4) this knife sharpener adopts slotted wheel interrupted grinding method, the grinding speed height, and highly polished, blade is sharp, and is unannealed.

In conjunction with the accompanying drawings, further specify embodiment of the present utility model.

Fig. 1 is the front section view of the utility model electric knife sharpener.

Fig. 2 is the side sectional view of the utility model electric knife sharpener.

As depicted in figs. 1 and 2, electric knife sharpener of the present utility model, comprise: plastic feet 19, can be contained on the described plastic feet 19, the surrounding, top is along being provided with the convex edge and center of top has the plastic casing 4 of a circular-shaped, concave cavity, the transparent plastic outer cover 1 that can cooperate with the described convex edge of described plastic casing 4, be fixed on power transformer 14 on the described plastic feet 19 by screw 11, attaching plug 18, switch 17 also are installed on described plastic feet 19; Permanent magnet direct current motor 13 is fixed on the described circular-shaped, concave cavity bottom surface of described plastic casing 4 by screw 9, tighten on 13 on described motor and intrinsicly to turn 8, turn and be provided with stage clip 6 in 8 the groove, grinding carriage 7 covers described through stage clips 6 turns on 8, and and described motor reel be slidingly installed, by resin emery wheel 5 is bonded on the described grinding carriage 7, and baffle plate 2 is installed in the end face of described emery wheel 5.Also be provided with diode 10 at described transformer 14 end faces, form the circuit part of the utility model electric knife sharpener by switch 17, button 12, plug 18, diode 10 etc.

The operation principle of electric knife sharpener of the present utility model is such, and 220V, 50HZ power supply are delivered to transformer 14 through switch 17, and 220V voltage is become 12V voltage, again through diode 10 full-wave rectifications becoming 12V DC powered motor 13.When pressing the button 12, connect switch 17, motor 13 is with 15000 rev/mins of rotations at a high speed, by turn 8, grinding carriage 7, drive emery wheel 5 and make the motion of 20 meter per second linear velocities, grinding blade.

For making blade sharp, must keep the cutting angle of cutting edge, electric knife sharpener of the present utility model is by the location of baffle plate 2, makes that the smear metal angle remains in the 10-30 degree angle when grinding kitchen knife, broadsword, fruit knife etc., is about 75 degree angles during the grinding scissors.This knife sharpener has adopted slotted wheel interrupted grinding method, makes grinding resistance little, and scrap rate increases, and is time saving and energy saving, and, behind the abrasion of grinding wheel, can adjust the emery wheel height to best grinding position by screw 3.In order to control the pressure that contacts of cutter and emery wheel, stage clip 6 is set, pressure can be adjusted within the specific limits automatically, prevent that artificial pressure is excessive and shut down.Electric knife sharpener integral body of the present utility model is the egg-pair circle of 150X76X100, good looking appearance, small and exquisite.

During use, open outer cover 1, hold shell 4 and press the button 12 and make emery wheel 5 rotation at a high speed; Desire is whetted a knife actinal surface to emery wheel, and scissors is put into by the slit, top, and kitchen knife, fruit knife etc. is put into by two side clearances, the contact emery wheel; At the uniform velocity cutter is pulled out from inside to outside and get final product.
