Description

Flexible planer knife

The present invention relates to a kind of planing tool that is used to cut the melon and fruit epidermis, particularly relate to a kind of cutting tip that can make by melon and fruit surface configuration continuous bend, and can in working angles, change with the melon and fruit surface configuration, realize planing tool to the flexibility (flexible slightly) of pericarp large tracts of land, quick, smooth cutting.

When being to use, the characteristics of existing Fruit peeler (fruit knife, planing tool) must carry out Multiple Cycle (or coming and going) cutting along the melon and fruit surface, the track in cutting face is a curve on the two dimensional surface each time, the shortcoming of this cutting element at first is that stock removal action repeats, and spended time is many; Next is to be difficult to grasp, and causes waste easily.The repeatedly contact of hand during simultaneously owing to cutting, the melon and fruit surface is also contaminated easily, and the cutting face is also rough, not attractive in appearance.

The present invention is made up of flexible (promptly flexible slightly, the also available chain of being convenient to bending) knife rest, blade support, elastic blade.Characteristics are to make knife rest together with blade, press melon and fruit surface configuration continuous bend, make it the smooth shaped form blade contact melon and fruit epidermis that is formed by connecting of the circular arc of different curvature.So the cutting face is more smooth, attractive in appearance than former melon and fruit surface.Around melon and fruit axis rotation firmly, when blade and knife rest rotated to each footpath line position, the curvature of each section circular arc changed during cutting, and knife rest and blade can change with surface configuration, revolve the three-sixth turn cutting and finish, blade is deviate from from pericarp, and this moment, pericarp still wrapped in the melon and fruit surface.Need only hand when edible pinch melon and fruit axis two ends and erase pericarp gently, just expose cleaning, bright and clean, mellow and full, pure white cutting face, thus realize to pericarp large tracts of land, smooth, at a high speed, the working angles of cleaning.Because cutting the cutting face of gained each time is a three-dimensional curved surface (blade support is divided into several piece with pericarp simultaneously), this cutting beyond doubt efficiently.

The present invention can be according to difformity, Intensity Design.Be used for the cutting of all kinds of melons and fruits.

The present invention also can make up with other cutter, forms multi-functional melon and fruit cutting tool.

The present invention compares with existing cutter as mentioned above, have easy and simple to handle, peel thin and evenly, advantage such as sanitation and hygiene, cutting face are smooth, attractive in appearance.Make that small product size is little, in light weight, easy to carry, cost is low, trial production cycle weak point, small investment, technology are simple, draw materials conveniently (major part of drawing materials is plastics, or other flexible material and light sheet on a small quantity).Be easy to produce in enormous quantities,, also can save a large amount of non-ferrous metals from macroscopic perspective.

Referring to Fig. 1-6, figure intermediate slide 1 usefulness flexible (the flexible slightly also available chain of being convenient to bending) material is made, can be by melon and fruit surface configuration continuous bend.Be embedded with blade support 3 on the knife rest 1, have tool bore 8, elastic blade 2 on the bearing, from each tool bore, run through, the gap (blade single face opening) that can make the moving displacement of blade string is arranged between tool bore 8 and the blade 2.Cutter groove 9 is protected at the tip of tool bore 8, and the effect of protecting cutter groove 9 is to prevent that the edge of a knife from directly contacting with blade support 3 and the cutting edge of a knife or a sword mouth of consulting and hindering blade 2.Blade support 10 fuses each blade support 3 in knife rest 1 in flakes, and blade support 3 has branch dermatotome mouth in cutting direction (right side).

The back side of knife rest 1 has is convenient to push away the projection of holding 6, and its inner face that contacts with pericarp is a sphere shape spigot surface 5.For the variation (in the certain limit) that knife rest 1 is convenient to adapt to various curvature, spigot surface 5 and projection 6 all have distortion groove 4 and 7.

When spigot surface 5 and pericarp were fitted, blade 2 was along with knife rest 1 distortion and parallel with spigot surface 5 all the time, and the distance between these two horizontal line circular arc lines is exactly the peel thickness when cutting.If regulate the distance between the two, peel thickness is just different.If designs fix spigot surface 5, each cutting all is the pericarp of thickness basically identical; If design activity spigot surface 5 makes it and can move up and down, then can cut peel thickness as required.Distance h between blade 2 and the knife rest can make pericarp withdraw from glibly greater than when cutting peel thickness, reduces cutting resistance.

Moment when blade 2 has just advanced pericarp as can be seen from Fig. 3,4, (sphere that promptly leads has a knife angle α between the circular arc tangential line of this point for the following edge of a knife of blade 1 and melon and fruit ₁+ α, the α angle disappears when entering cutting state, remaining cutting angle α ₁, α ₁More approach null value, cutting is more fluent, and the cutting face is more smooth, required cutting thrust F ₁Also little; And work as α ₁Cutting tip 2 cuts out from pericarp 12 during for negative value, and cutting can not be proceeded; Secondly if α ₁Very big then cutting resistance is also very big, and the cutting face is also rough, and blade also is easy to split off (blade 2 is thinner during design, and certain degree of hardness is arranged, and just the sharp edge of a knife can be arranged, and cutting resistance is reduced, and reduces the quantity of blade support 3).And the curvature of in fact all kinds of melons and fruits has the variation of certain limit, and we can not remove to manufacture and design a cutter for the fruit of a fixed dimension, so should have 3 ° with interior cutting angle α ₁, cutting resistance can't increase like this, the cutting face is also comparatively smooth.

Among Fig. 3-7, thrust F ₁Power thrusts (promptly rotating the direction of relative movement of broaching power around the melon and fruit axis) for promoting knife rest 1 produces a F during blade 2 incision pericarps 12 ₂Pulling force make the spigot surface 5 of knife rest 1 more be adjacent to the melon and fruit surface.Tool support 3 stays equally distributed minute skin groove 13 of broadwise on pericarp, pericarp 12 is divided into some rectangular, and pericarp 12 relies on the bonding force of its elastic force that resiles and fruit juice, still is attached to the surface of melon and fruit 11, and the cutting face is still a sphere to outer closure.Knife rest 1 can not contact the cutting face with hand, need only erase pericarp lightly when edible, will expose smooth, cleaning, pure white cutting face.Because the cutting face is the sphere of the smooth connection of each piece, so more more regular, mellow and full than former melon and fruit surface.(we carefully observe the melon and fruit surface configuration and are actually rough).

See Fig. 5, top S ₁Be the shape of existing Tool in Cutting pericarp, S ₂Be the shape of the cutting pericarp of planing tool of the present invention, obvious S ₁Area＞S ₂Area, cutting face also are S ₂Smooth.

See Fig. 6,7, the curvature of knife rest 1 is greater than melon and fruit 11 surface curvatures, and knife rest 1 and melon and fruit are fitted.And after entering cutting state, knife rest 1 just is subjected to interlock figure F ₂And F ₃Force action, make the spigot surface 5 of knife rest 1 inner face more be adjacent to the melon and fruit surface, pericarp is controlled to be made thinlyyer, also is difficult for blade 2 during cutting and skids off pericarp 12, but can not be too thin, thinner F ₂Also little, and there is certain concave-convex on melon and fruit 11 surfaces, the part cutting is so just arranged easily less than concave surface, so should make during design pericarp still one the thickness of deciding be arranged between 0.3～1mm.

Fig. 8, Fig. 9 are the left front views that does not have grooved around fruit axle rotary cutting, and its cutting principle as before.Difference is that blade 2a and blade support 3a are an integral body, the strap 16 that is embedded in knife rest 1 in each bearing hole 15, strap 16 and with holes between have can displacement the gap, blade support 3a is not staying the broadwise vestige on the cutting face at melon and fruit during cutting.

More than two kinds be around 360 ° of cutters that disposable cutting finishes of fruit axle rotation.See Figure 11, the 12nd, be applicable to rectangular easy cylindrical melon and fruit cutting tool, its cutting principle is with noted earlier consistent, and difference is that spigot surface 5a is half-cylindrical, cutting thrust F _1aAlong melon and fruit axis direction horizontal drawing, rather than pivot,

Flexible planer tool of the present invention can be according to difformity, requirement of strength, be designed to the various uses flexible planer tool of (comprising specific use), be used for all kinds of melons and fruits (as essentially smooth melons and fruits in surface such as apple, pears, gold melon, pears melon, peach, snake melon, Hu Lu, watermelon peel, cucumber, potatoes) epidermis cutting.

The flexible knife rest material therefor of flexible planer tool of the present invention is: flexible knife rest 1 can be nontoxic to material requirements with plastics or other flexible material, is difficult for wearing out, and flex capability is subjected to variation of ambient temperature less; Elastic blade 2 and blade support 3 usefulness stainless steels or other stalloy of handling through surface anticorrosion are made, and certain rigidity is arranged.
