Abstract

The invention relates to a vegetable cutter with synchronous function, which belongs to the food processing machinery. The invention provides a novel vegetable cutter series, and various diced vegetables, shredded vegetables and vegetable slices can be cut out and molded at one time. The vegetable cutter adopts the technical proposal that the theory of relativity is applied, and three-dimensional cutting is completed by using one cutter head. (Refer to appended drawings in abstract), all cutting tools are arranged on the identical cutter head, a cutter head (5) and a charging barrel (3) are rotated synchronously relative to each other, two vertical knife assemblies are installed at certain angle intervals, and therefore, the charging barrel carried with material is rotated for a certain angle when the vertical knife assemblies (6) and (7) cut by the charging barrel in sequence. Two groups of mutually intercrossed longitudinal notches are cut out; and then a layer of material with a longitudinal notch is cut off by a flat knife, namely, diced vegetables. The shredded vegetables or the vegetable slices can be respectively cut out when one or two vertical knife assemblies are positioned in the nonoperative position. The invention has the advantage that the problem that the shredded vegetables and the diced vegetables are molded at one time is solved.

Description

Function synchronizing vegetable cutter

Affiliated technical field

But the invention of this reality is the food processing machinery of a kind of edible dish sheet of cutting all size, dish silk (bar), dish fourth (comprising dumpling farcing).Also can be applicable to green forage processing.

Background technology

Cognitive at present vegetable-chopper is divided into three major types substantially.One class vegetable-chopper is reciprocating type.Need pass through multiple clamping with this mechanical cutting dish silk, dish fourth, repeatedly feed, efficient is low, and finished form is irregular, and the size difference is big.Second class is to adopt the grid cutter, makes bar and then cuts into the dish fourth with fashion of extrusion earlier.Also adopted hydraulic pressure and the computer that have are controlled.This class machinery can not continuous operation, and mechanism is cumbersome, the cost height, and goods that can not the cutting reduced size, and also the loss of dish juice is serious.The 3rd class vegetable-chopper adopts the cutting knife of rotation at a high speed, random cutting, and similar beater, the finished product after the cutting do not have definite shape and the most of loss of dish juice, can only be used for feed processing.

Summary of the invention

Develop a kind of high-performance vegetable-chopper, it both can cutting dish delivery sheet, dish bar, dish fourth, can add many special shapes again, as wave bar, sphere piece, four sides piece, five pieces, octahedral piece etc., and, can both directly process bulk, wide leaf, bar shaped leaf vegetables.Need only once drop into vegetables, a feed, promptly go out finished product.

Cutting mode

Vegetables fixing after, select a machined surface.On this same machined surface, cutting out two groups earlier has certain depth, the cross one another longitudinal cut of direction, then the vegetables that this one deck had a longitudinal cut with horizontal cutting knife downcut the dish fourth.

Mechanism is provided with analysis

Set a rotating cutter-head, with two vertically (vertical cutterhead planes) the upright cutter group of installing respectively be installed in across a certain distance mutually on this same cutterhead with a flat cutter of installing with the cutterhead plane parallel and (see Figure of description 1), allow all cutters with this cutterhead synchronous operation, to simplify mechanism.If material is motionless, during the work of the cutterhead of this spline structure, two upright cutter groups on the dish are along same orbiting motion, and in other words, two cutter groups can only play a cutter group, only cut out one group of longitudinal cut.For this reason, must allow material after being cut by previous upright cutter group RelativelyCutting knife turns over after the angle, again by back one upright cutter group cutting.Like this, two found the otch intersection that the cutter groups are done.Then, this one deck has and intersects the flat cutter that the material of longitudinal cut cut subsequently and downcut, and is the dish fourth.

Should be emphasized that: should note the front said ' Relatively', it is emphasized might not be the absolute movement of material as long as material has one to relatively rotate to cutting knife, certainly, absolute movement also is the same effect.

Brief summary: the characteristics of above mechanism and work thereof are---two Synchronously, two RelativelyTwo are synchronously--1. all cutters all are contained in synchronous operation on the same cutterhead; 2. relatively rotating of cutter and material is synchronous.Two are relatively--1. when supposing that material is static, the relative material of cutting knife relatively rotates, to finish the cutting to material; 2. when supposing that cutting knife is static, material relatively rotates the cutting knife group, to change the cut direction between the two upright cutter groups.

The technical solution used in the present invention is:

By principle described above, type can have multiple, and existing is that example describes with a kind of the most two dead axle function lazy-tongs.

(consulting Figure of description 1) power is imported by power input pulley (1); Driving wheel (2) is connected by synchronous band (4) with barrel (being embedded with synchronous pulley) (3), and (2) (3) pulley diameters is identical.Belt pulley (1), (2) and cutterhead (5) are coaxial and be fastenedly connected by key.So barrel in the course of work (3) and the equidirectional rotation of cutterhead (5).Material is packed into and is rotated with barrel behind the barrel.Two upright cutter groups are installed on the cutterhead (5) by knife rest (9) separately, its blade can pass the bar hole of cutterhead when the operating position, reach the above certain altitude of cutterhead upper surface (consulting Figure of description 4), by direction of rotation shown in Figure 1, upright cutter group-2 (7) lags behind upright cutter group-1 (6) certain angles, every certain angle flat cutter is fixed on the cutterhead and (consults Figure of description 3,5).Upright cutter knife rest is adjustable, and they all respectively have an operating position and an off-position (consulting Figure of description 4,6).The two structure is identical, all is equidistantly to be fixed on the cutter shaft by some blades perpendicular to cutterhead.So, when upright cutter group-1 (6) was cut the cut material of exposing barrel (3) lower end, just on cut material, cut out one group of longitudinal cut (identical) that certain depth is arranged with feedstock direction, when barrel turned over 90 °, cutterhead also turned over 90 °.So upright cutter group-2 (7) was cut the material of barrel lower end just, therefore cut out another the perpendicular group longitudinal cut of otch that cuts out with upright cutter group-1 (6).When flat cutter (8) was cut the material of barrel lower end, make transverse cuts (vertical) with feedstock direction, will have and intersect one deck material of longitudinal cut and downcut, be the dish fourth.

Directions for use

(1) when cutting dish fourth, upright cutter group-1 (6) all places the operating position with upright cutter group-2 (7).At this moment, two upright cutter groups and flat cutter are all worked.

(2) when cutting dish silk, dish bar, place off-position to get final product one of two upright cutter groups.This moment, upright cutter group-1 (6) moved down, and its blade is lower than the cutterhead end face, had only upright cutter group-2 (7) and flat cutter work.

(3) when cutting dish sheet, two upright cutter groups are all placed off-position, have only flat cutter work.

Below, be example with the said mechanism, with the feasibility of the above design of mathematical analysis method demonstration.

Two upright cutter group otch angles are analyzed

Consult Figure of description 1, the rotating speed of establishing the relative material of cutter is ω ₁, the rotating speed of the relative cutter of material is ω ₂, ω again ₂=K ω ₁, it is α (consulting Figure of description 1) that two upright cutter groups are installed angle, and the working time is t, and the angle that material turns in the t time is θ,

θ=ω then _2t

So θ=K ω ₁t

Work as ω ₁During t=α, (angle that two upright cutter groups are just successively passed through)

θ=K α (angle that same time material turns over) then

As can be seen: 1. when K=1

θ=α then

In other words: during K=1, the angles of two upright cutter otch equal the angle α between the installation site of two upright cutter groups.When α=90 °, just can cut out square dish silk and dish fourth, otherwise be rhombus.

2. when K ≠ 1, θ=K α

Promptly the angle of two upright cutter group otch is its K times that angle α is installed, and adjustment K α value makes it equal 90 ° can cut out square dish fourth; Otherwise be rhombus dish fourth.

Single upright cutter cutting movement trajectory analysis

Shown in Figure of description 7, cutterhead (5) is around XO ₀The O of Y coordinate system ₀Point is with ω ₁Speed rotates counterclockwise, and barrel (3) is around coordinate system X ₁O ₁Y ₁Initial point O ₁Do dead axle and rotate, rotating speed is ω ₂O ₁Point is at XO ₀Coordinate in the Y coordinate system be (0, b).We will found any one blade B in the cutter group _nWith the relative motion of material as object is discussed.

Suppose B at a time _nCutter moves to the C point, and cutter was actually by two components the absolute cutting speed of material and formed this moment: one is to suppose that material is motionless, B _nCutter is with the speed V of cutterhead motion _oAnother is supposition B _nCutter is motionless, the relative B of barrel _nThe moving cutting speed V that forms of swivel ₁The two direction of motion as shown in Figure 7.In order to make cut surface is the plane, necessarily requires V _oAnd V ₁Resultant motion be zero at the component of Y direction, thereby resultant motion is zero in the displacement component of Y direction.

Because B _nBlade is to be fixed on the cutterhead, and its radius of turn is definite value R.

We ask V earlier _oComponent V in the Y direction _Oy

B _nCutter is for XO ₀The track side of Y coordinate system becomes:

X ²+Y ²＝R ²———————————①

General side becomes 1. to turn to parameter side and becomes:

∵X＝R?cos?φ

φ＝ωt

∴X＝Rcosωt

Formula turns to so 1. the side becomes:

Y ²＝R ²-(Rcosωt) ²

Y ²R ²Sin ²ωt

Y＝R?Sinωt --------②

(because the operating position only limits to XO ₀Y coordinate system I, II quadrant, thus only get on the occasion of.)

2. formula is B _nCutter is for XO ₀The displacement equation of Y coordinate system.Therefore, incite somebody to action 2. formula

Be written as:

Y ₀＝R?Sin?ωt ---——-----③

If V ₀Component along Y direction is V _Oy,

V then _Oy=(y _o) '

V _oy＝Rω?conωt

Ask V below ₁Component V along Y direction _1y:

If C (material) point is around O ₁The radius of gyration be r.At right angle trigonometry type △ O ₁Among the DC,

r ²＝O ₁D ²+DC ²

O again ₁D=b-R Sin ω t

DC＝R?conωt

∴ $r=\sqrt{{(b-\mathrm{RSin\ωt})}^2+{\left(R\cos \mathrm{\ωt}\right)}^2}$

$r=\sqrt{b^2-2\mathrm{bRSin\&omega;t}+{\mathrm{<figure-callout\; id="2"\; label="R"\; filenames="A200810098923E00161.png"\; state="\{\{state\}\}">R</figure-callout>}}^2}$

More than analyze as can be seen: r also is the function of ω t

If K is the gearratio between cutterhead and the barrel,

V then ₁=r ω ₁

ω ₁＝Kω

V ₁＝rKω

Cross the C point and be the parallel lines of X, Y-axis, then ψ respectively ₁=ψ ₂(corresponding sides are vertical mutually).

So V _1y=V ₁Cos (π-Ψ ₁) (because V ₁With the angle of Y-axis positive direction greater than 90 °)

V _1y＝-KrωcosΨ ₁

∵ cosΨ ₁＝cosΨ ₂

Again at right angle trigonometry type △ O ₁Among the DC,

$\cos {\mathrm{\&Psi;}}_2=\frac{\mathrm{DC}}{r}$

∴ $\cos {\mathrm{\&Psi;}}_1=\frac{\mathrm{DC}}{r}$

cosΨ ₁＝R?cosωt/r

∴V _1y＝-Krω?Rcosωt/r

V _1y＝-Kω?Rcosωt

So B _nCutter to the aggregate velocity of material along the component of Y direction is:

V _y＝V _oy+V _1y＝Rωcosωt-KRωcosωt

V _y＝Rω(1-K)cosωt --------④

Therefore, B _nThe resultant motion of cutter and material becomes the displacement side of Y-axis:

Y＝∫Vydt

Y＝∫Rω(1-K)cosωtdt

$Y=\mathrm{R\&omega;}(1-K)\&CenterDot;\frac{1}{\mathrm{\&omega;}}\&CenterDot;\mathrm{Sin\&omega;t}+C$

Y＝R(1-K).Sinωt+C----—-⑤

Discuss:

(1) as can be seen by 5. formula, when K=1,

Y＝C

Y is the straight line that is parallel to the x axle.

(2) K ≠ 1 o'clock, Y is a cosine function, its movement locus is a curve.

In sum: above mathematical analysis is summed up as two functions.The angle of (one) two upright cutter group otch is the function that the gearratio K and two of cutting knife and material founds angle α between the cutter group installation sites; (2) curvature of otch is the function of the gearratio K of cutterhead and barrel.

The beneficial effects of the utility model are: solved cutting dish silk, the one-time formed problem of dish fourth.And simplify the internal structure of an organization, reduce cost, improve functional reliability, reduce cutting resistance, energy efficient.There are not extruding, impact cutting (cutting).Protect slurry and protect fragility, the goods mouthfeel is good.

The specific embodiment

Implementing above scheme can have multiple mode, from kinematic angle, can be divided three classes substantially.Division is as follows:

1. two dead axle function lazy-tongs: all relative support with cutter of material is done absolute motion, and promptly material is done the dead axle rotation, and cutting knife is also done dead axle and rotated (kinematic sketch of mechanism is seen Fig. 8,9).

2. cutterhead translation function lazy-tongs: the relative support of material is static, and cutting knife is along being the round translation (kinematic sketch of mechanism is seen Figure 10,11) in the center of circle with the barrel center.

For the ease of understanding, be necessary to present a new concept: (seeing Figure 12) rigid body can be decomposed into when being the round translation in the center of circle with 0: rigid body is with basic point O ₁Do dead axle around fixed point o and rotate, self is again with basic point O simultaneously ₁For axle rotates.Also we can say ' surely round translation ' by two independently dead axle rotate and combine.Among Figure 12, cutterhead (5) is that the round translation in the center of circle promptly is made up of two dead axles rotations along the center 0 with barrel (3): one is that cutterhead is with its garden heart O ₁Dead axle rotation for axle; Another is that cutterhead is with basic point O ₁Rotate in fixed axis around 0.By shown in Figure 12, though barrel is static, 0 dead axle of palette knife coiling rotates this component motion, promptly is equivalent to barrel and rotates in fixed axis around 0.So, motion of mechanism mode and two dead axle function lazy-tongs equivalences.

The 3rd class＜material translation function lazy-tongs〉therewith in like manner.

3. barrel translation function lazy-tongs: the relative support of cutting knife is static, and material is done translation (kinematic sketch of mechanism is seen Figure 13,14) along the circle that with the cutter axis is the center of circle.

Though above variety of way form is different, principle is identical, can be divided into two classes that differ from one another.One class is a belt transmission, and mechanism shown in Fig. 8,10,13 is arranged.Material is identical with the cutterhead direction of rotation.The characteristics of this class mechanism are: the otch curvature of cutting knife on material is less, and the guiding mechanism parameter can be adjusted to straight line with otch; Two classes are gear drive, and the mechanism shown in Fig. 9,11,14 is arranged.Material is opposite with the cutterhead direction of rotation.The characteristics of this class mechanism are: the otch curvature of cutting knife on material is very big, can surpass semicircle.Also can adjust otch curvature on request.More than two class types can optionally select.Also can change type with the method for transposing drive (belt wheel or gear).

It is manual type that the principle of type shown in Figure 13 also is well suited for transplanting.As shown in figure 15, complete machine has only a simple cutterhead and a barrel.As long as material is dropped into barrel, one hand is held barrel and is pinned material and slide along the guide groove of cutterhead during work, output promptly be upright dish fourth or straight dish silk.Operate very simply, effect and motor-driven type are identical.
