Abstract

The utility model relates to a sharpening machine suitable for sharpening various cutters, which is composed of a motor, abrasive wheels, knife supporting wheels, a bracket, a pressing spring and a backplane. The abrasive wheels and the knife supporting wheels are arranged on a rotary shaft. The pressing spring is arranged between the two knife supporting wheels between the two abrasive wheels. The positions near shaft holes on the knife supporting wheels are provided with convex disks tightly fitted with concave disks on the corresponding positions on the abrasive wheels. A gap is formed between the circular arc surface on a knife supporting wheel and the surface of an abrasive wheel. The utility model has the advantages of labor saving and high speed, and the utility model can also lighten labour intensity of sharpening.

Description

Knife sharpener

The utility model is a kind of knife sharpener.

Family kitchen is more and more cleaner and tidier at present, kitchen utilities is modernization more and more, people spend at the labour intensity of cooking a meal on burning and have alleviated greatly, give the very big convenience of having brought in life, the kitchen has something also not make us break away from heavier work in cooking a meal and burning, whet a knife exactly and still continue to use original sharpening method method, adopt the mudstone bar, sandstone piece or oilstone instrument are whetted a knife.Can grind not only time-consuming but also require great effort, simultaneously careful again.Particularly woman and aging people really cut the dish easily, whet a knife " difficulty " so a lot of people are afraid of to whet a knife very much!

The utility model design is adopted slightly, fine sand is taken turns and the cutter support roller reasonably makes up, by driven by motor, and the barreling cutter.It includes motor, emery wheel, cutter support roller, top pressure spring, support and base plate, its feature is that long key is installed in the rotating shaft on emery wheel, the cutter support roller, and can move axially, in two cutter support rollers between thick, the fine grinding wheel, dispose top pressure spring, the cutter support roller has outstanding garden face by the axis hole position, and there is recessed garden face at the position that the emery wheel lining is corresponding with it, and both match.Being a bit larger tham apart from length of its protrusion is recessed apart from length, and the garden cambered surface of cutter support roller forms a tiny space with plane of grinding wheel.

The utility model biggest advantage is to replace manual the sharpening, and the space between cutter support roller and the emery wheel makes in the middle of blade is close to, and can not fall to running into rotating shaft, and is during use, safe, reliable, light, laborsaving, save time.

Now in conjunction with the accompanying drawings, embodiment of the present utility model is further specified.

Fig. 1 is a topology view.

Fig. 2 is the structure zoomed-in view at A position.

Fig. 3 is the shape end view of rotating shaft and emery wheel, cutter support roller junction.

Fig. 4 is the axis hole shape view of emery wheel, cutter support roller.

Two emery wheels 3 in the utility model structure, one is coarse plain emery wheel, another is fine grinding wheel and four cutter support rollers 2, be contained in the same rotating shaft 4 by long key 6, rotating shaft 4 is with a left side, right support flexibly connects, one end is connected in motor 7 rotating shafts by shaft coupling, drive

emery wheel

3 and 2 rotations of cutter support roller, two thick, fine grinding wheel 3 and two cutter support rollers 2 in the centre can move axially, two cutter support roller 2 activity orientation on both sides are on a left side, on the right support 1, device has top pressure spring 5 between the wherein middle two cutter support rollers 2, realizes two slightly, fine grinding wheel 3 and four cutter support roller 2 tight fits.Two emery wheels 3 are socketed in the rotating shaft 4 by lining 9, the outer garden of lining 9 has recessed garden face near axis hole 10 positions are corresponding with it protrusion garden face to be arranged with cutter support roller 2, both tight fits, protrusion garden face protrude apart from length a be a bit larger tham recessed garden face recessed apart from length b, the garden cambered surface of cutter support roller 2 and emery wheel 3 planes form a thin space, the blade of cutter matches with the space, avoids blade to fall to contacting rotating shaft 4.Emery wheel 3, cutter support roller 2, motor 7 and rotating shaft 4 are installed on the base plate 8 by left and right support 1 and motor bearing.The protrusion that the cutter support roller 2 of this knife sharpener protrudes the garden faces adopts different sizes apart from the recessed distance b of the recessed garden face on a and the emery wheel 3, can be suitable for the various large and small cutters of mill.
