Abstract

An electric sharpening device for cutting edges is principally used for sharpening kitchen knifes and household small knife tools, capable of resolving trouble of manpower sharpening. In a plastic casing having a V-shaped opening, a series excitation type motor is connected with two coaxial worm shafts which screw threads are opposite; and the two worm shafts cross a bearing and are extended as the driving shafts of two sharpening wheels. Each sharpening wheel is composed of a column-shaped abrasion wheel, a spring and a I-shaped support, two sharpening wheels are arranged on two sides of the V-shaped opening to sharpen the cutting edges. The worm shafts cross a bearing and are extended outside the casing, a wafer-shaped abrasion wheel is arranged on one end of the worm shaft to sharpen small knife tools with short edges.

Description

Electric knife grinder
Technical field: the utility model relates to a kind of electronic knife sharpening device, is mainly used in the polishing of kitchen kitchen knife and the little cutter of family expenses.
Background technology: the known mode that sharpens a kitchen knife mainly is that manpower is whetted a knife at present.Manpower mill power not only wastes time and energy, and sharpening person is had certain technical requirements, and main points there are not grasp to be difficult to grind suitable receipts sharp angle degree and sharp cutting edge.
Summary of the invention: reach time saving and energy saving in order to make to whet a knife, purpose simple to operate, the utility model is achieved in that in the plastic casing that has " V " shape mouth, the reverse each other worm shaft of a single-phase series excitation type motor and two snail lines is to stressed joint.The other end of worm shaft passes a bearing and extends to outside the casing, and a disk shape emery wheel is installed in its end; Two worm screws respectively cooperate a worm gear; Column emery wheel, spring, " worker " shape are propped up and are configured to grinding wheel, two worm-wheel shafts pass bearing and extend as two grinding wheel driving shafts, the two grinding wheels blade that is placed in is put into " V " shape mouth both sides, the centre-to-centre spacing of two grinding wheels is less than the diameter of grinding wheel, the column emery wheel of two grinding wheels is as the tooth of two interlock gears, staggers mutually in its position.Blade is put into two ends, " V " shape mouth bottom respectively " V " shape groove pulley, and " V " shape trench bottom angle of pulley is less than the receipts sharp angle of kitchen knife, so that edge does not touch " V " shape bottom land.Because two worm screw snail lines on the same axle are reverse each other, cooperate worm gear drives two sharpening crop rotation " pair roller " shapes rotations respectively, the column emery wheel on two grinding wheels then respectively the two sides of tool setting do from blade to the polishing of edge direction because the effect of spring makes the column emery wheel is about 2 centimetres to the polishing depth width of blade.Blade dragged from " V " shape mouth, and just by polishing one time, another effect of spring is, when the column emery wheel still can effectively be whetted a knife when to a certain degree wearing and tearing on the blade two sides.Disk shape emery wheel is mainly used in the polishing of the little cutter of short sword.In addition, because worm screw tool auto-lock function when changing the column emery wheel, must be stirred disk shape emery wheel and the column emery wheel on the grinding wheel could be adjusted to the position that is fit to replacing.
Description of drawings: the utility model is further specified below in conjunction with accompanying drawing.
Fig. 1 is the utility model complete machine structure schematic diagram.
Fig. 2 is among Fig. 1 " worker " shape support schematic diagram.
Fig. 3 is among Fig. 1 Column grinding wheel shape figure.
Fig. 4 is among Fig. 1 Sharpening wheel shaft schematic diagram.
Fig. 5 is among Fig. 1 Spring shape figure.
1. series excitation type motor among the figure; 2. machine base; 3. right line worm screw; 4. dextrorotation worm gear; 5. " V " shape groove pulley; 6. grinding wheel bearing mounting; 7. left line worm screw; 8. left-handed worm gear; 9. worm shaft; 10. worm bearing mounting; Disk shape emery wheel; Plastic casing; Spring; The column emery wheel; " worker " shape support; The sharpening wheel shaft; Sharpening wheel shaft pilot hole; Spring movable end slide slot; The spring fixed screw holes; The spring movable end; Column emery wheel pilot hole; Spring fixed end; The emery wheel holddown groove.
The specific embodiment: in Fig. 1, series excitation type motor 1. power is 50 watts, joins a button power switch and is contained on the plastic casing.The speed reducing ratio of worm and wormwheel is 20: 1, and modulus is 1.5.The grinding wheel diameter is 60 millimeters, and two grinding wheel centre-to-centre spacing are 50 millimeters, and " worker " shape support length and width all are 40 millimeters, spring fixed hole Front end when being in motion, spring Making steel wire diameter is 0.8 millimeter.The column abrasive wheel end face is the square of 10 millimeters of the length of sides, highly is 18 millimeters, on the distance top 10 millimeters locate two relative sides respectively open one wide 0.9 millimeter, dark 2.5 millimeters groove is in order to be fixed on spring The place, column emery wheel groove is coated with one deck resin glue, prevents the damage of emery wheel to spring, with corresponding bottom chamfering of fluting, be convenient to emery wheel is inserted spring emery wheel pilot hole Just turn 90 degrees and it easily can be dialled down as long as the column emery wheel revolved, be convenient to replacing.The sheet emery wheel 30 millimeters of diameters, 6 millimeters of thickness; In the tapping of worm shaft top, with fixed by nut sheet emery wheel The plastic casing top is respectively established one and is fastened lid in the position of two grinding wheels, be convenient to change the column emery wheel.

Claims (1)
