Abstract
The utility model discloses an electric sharpening device for knives and scissors, which is added with a sharpening guide frame composed of an upper cover and a cutter supporting frame on the basis of the existing electric sharpening device composed of an electric machine, a power supply, and grinding wheels to form three x-shaped sharpening grooves, wherein, one side of the middle groove is vertical, and the other side of the middle groove is sloping. The grinding wheels are arranged under the x-shaped crosspoint, and the sharpening knives and scissors haves fixed blade angles. A shaft connecting plate is movably connected with a grinding wheel seat sticking with grinding wheels and a spring is arranged between the shaft connecting plate and the grinding wheel seat, which can adjust the height of the grinding wheel and control the sharpening single-side and two-side knives, scissors, etc. with lighter force.
Description
The utility model relates to a kind of Sharpening device that is used for cutting edge, relates to a kind of electronic sharper that cutter is cut a class instrument that is used for or rather.
The electronic sharper of existing replacement hand grinding, as Chinese patent CN87213126.2, its basic building block comprises the plastic barrel of motor, battery and profile such as flashlight, the outer motor axis of tube place sets up emery wheel, utilize the Grinding wheel Grinder of energising back rotation, the contact-making surface of blade angle, cutter and emery wheel and pressure thereof are fully by Artificial Control.
But the purpose of this utility model is to design the lighter power sharpening of a kind of usefulness the fixedly sharper of blade angle is arranged, can be used for the sharpening that the sharpening of single, double sword such as kitchen knife, fruit knife, table knife, pencil-knife and sewing scissors, hair scissors, office are cut etc.
Basic building block of the present utility model has increased the sharpening saddle that is combined by holder knife rest and loam cake except that comprising crust of the device, motor, power supply, emery wheel.Holder knife rest and loam cake all have
The shape face forms after both assembly
The shape groove has guaranteed that single, double edge has fixing blade angle when from left and right two grooves insertion of sharpening saddle cutter.On be stamped medial launder, the one side of groove is a vertical plane, another side is the inclined-plane.When scissors inserts from medial launder, the sharp edge of shear blade has just had fixing blade angle against the inclined-plane of medial launder.Three the sharpening grooves in the left, center, right of above-mentioned sharpening saddle are * shape, and its below, crosspoint is an emery wheel.
The rotation of motor drives grinding wheel stand by coupling disc and is bonded at emery wheel rotation on the grinding wheel stand.Adopt active the connection between coupling disc and grinding wheel stand, the centre has spirality to compress spring.Rely on them can regulate the emery wheel height automatically, change emery wheel and carry out sharpening with lighter power.
Describe the utility model in detail below in conjunction with embodiment.
The perspective view of accompanying drawing 1. electronic sharper loam cakes
The perspective view of accompanying drawing 2. electronic sharper holder knife rests
The perspective view of accompanying drawing 3. electronic sharper main bodys
Accompanying drawing 4. electronic sharper complete machine structure schematic diagrames
The method signal that the electronic sharper of accompanying drawing 5. usefulness is whetted a knife
The grind scissors method signal of cutter of the electronic sharper of accompanying drawing 6. usefulness
Fig. 1 shows the stereochemical structure of electronic sharper loam cake 1, loam cake
The shape face, with the angle theta 1 of horizontal plane be 16 °-20 °.Medial launder is arranged, and the one side of groove is vertical, and another side is inclination, and the angle theta 2 of inclined-plane and vertical plane is 15 °.The medial launder front end is a groove, and there is bridge shape holder cutter platform 2 rear end, has dark screw 3 on the holder cutter platform.
Fig. 2 shows the stereochemical structure of electronic sharper holder knife rest 4.Its
The angle theta 3 of shape face and horizontal plane is 16 °.Holder knife rest front end
The shape top bit is equipped with a rectangle by cutter groove 5, is embedded with metal and leans on blade 6 as copper sheet.Holder knife rest rear end
The shape top bit is equipped with by cutter platform 7.The holder cutter platform 2 of loam cake 1 is inserted leaning in the cutter platform 7 on the holder knife rest 4,, loam cake 1 and holder knife rest 4 are assembled together by a self-tapping screw, and forming the sharpening saddle, the sharpening saddle has three the sharpening grooves in left, center, right, is * shape, emery wheel is installed in its below, position, crosspoint.
Fig. 3 shows the stereochemical structure of electronic sharper main body, and wherein 8 is fuselage, and 9 is control button, and 10 is grinding wheel stand, and 11 is emery wheel, and 12 is bottom plate, and wheel face is positioned on the fuselage
The top on shape inclined-plane.
The sharpening saddle that assembles is inserted on this agent structure, holder knife rest 4
On shape face and this main body
The shape inclined-plane overlaps and is adjacent to, and forms structure shown in Figure 4.
13 is guard shield among Fig. 4, and 1 is loam cake, and 4 are the holder knife rest, 8 is fuselage, and 14 is motor, and 15 is the motor axis, 16 is coupling disc, and 10 is grinding wheel stand, and 11 is emery wheel, 17 are spirality compression spring, and 9 is control button, and 2 are holder cutter platform, 7 for leaning on the cutter platform, with 502 glue emery wheel 11 is bonded on the grinding wheel stand 10, grinding wheel stand 10 adopts active the connection with 16 of coupling discs, and there is spring 17 centre.When the sword face that is ground contacts with wheel face, can regulate the height of wheel face by spring, simultaneously also because the cushioning effect of spring force, help controlled pressure and, and grinding wheel stand is connected with the activity of coupling disc and also is convenient to change emery wheel with lighter power sharpening.
When grinding single, double blade, cutter stretches into from the sharpening groove on the left and right both sides of sharpening saddle, the holder knife rest
The shape inclined-plane has formed fixing blade angle naturally.Hold in the palm leaning on the cutter groove and playing the block positioning action by the tool setting of cutter platform on the knife rest simultaneously, make when sharpening, very easily control the motion of cutter, whole sword face comprises that its tip and root all can obtain abundant sharpening.
When grinding the cutter of single, double cutting edge, operation is put into the sharpening saddle with cutter as shown in Figure 5, with the cutter of one side mill single face cutting edge of sharpening saddle, and the cutter that grinds two-sided cutting edge with the left side and the right of sharpening saddle.1 is loam cake among the figure, and 5 for leaning on the cutter groove and leaning on blade, and 4 for the holder knife rest, presses control button, with lighter pressure that cutter is mobile backward, as shown direction.
When grinding scissors the cutting edge of cutter, as shown in Figure 6, a slice blade of scissors is put into the medial launder of sharpening saddle, the sharp edge of blade with the blade angle that guarantees to fix, is pressed control button against the inclined-plane of medial launder, with lighter power to pressing down and pulling back, direction as shown in FIG..
The utlity model has advantages such as simple in structure, in light weight, that sharpening is effective, fuselage, loam cake, holder knife rest, grinding wheel stand, coupling disc, bottom plate etc. all adopt ABS plastic.Do not analyse and observe part among Fig. 4 battery or other form power supplys are installed, as AC/DC convertor etc.
