Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a shredding device for shredding noodle strips into strips during the production of noodles.

(Prior Art) The forming grooves of conventional shredding rollers are formed so that the cross section of the rolled wire passing through the forming grooves is rectangular or approximately cross-shaped.

(Problems to be Solved by the Invention) Therefore, in the conventional rolled wire formed by a shredding roller or by hand, when the same rolled wire is boiled, the cross section of the rolled wire is rectangular or almost circular.

In addition, in order to give the rolled wire a characteristic cross-sectional shape, by pressing the cut wire as described above with one or both blade surfaces of the cutting blade, the wire is plastically deformed and shaped into a rhombus or other shape. Some attempts have been made to form it into a cross-sectional shape. However, the rolling wire used for cutting is made of dough that has both a certain degree of plasticity and a certain degree of elasticity. Therefore, even if plastic deformation is caused by instantaneous pressing force as described above, some degree of return to the shape is unavoidable. In particular, when noodles are boiled, they often return to their original shape. For this reason, it was not possible to satisfy consumers.

Therefore, an object of the present invention is to obtain a wire having a diamond-shaped cross section that does not undergo the above-mentioned shape reversion.

(Means for Solving the Problems) A means for solving the above problems is that in a shredding device for slitting strips into strips, the diameter of each cutting edge circle changes from one end of the roller shaft to the other end. A pair of conical shredding rollers each having blade groups arranged so as to gradually increase and decrease toward the sides are brought into contact with each other so that the large diameter side and the small diameter side of each shredding roller face each other. The cutting edge of each blade of these shredding rollers is made to protrude thinly into a pointed shape in the direction perpendicular to the roller axis, so as to face the cutting edge of the blade of the other shredding roller installed oppositely, and , a space of a predetermined width that allows the cut wire to pass through is formed between the cutting edge portions of each blade, and a tangential portion of both shredding rollers is set at an angle with respect to the roller axis of the shredding roller. It is to pass through the nimen belt.

(Function) The noodle strip passes between the two shredding rollers along the tangent line between the two shredding rollers, while the cutting edge of each blade of the shredding roller protrudes in a direction perpendicular to the roller axis. The obi is cut diagonally. Therefore, the rolled wire is cut into a diamond-shaped cross-section.

The cutting edge of the blade is thin and protrudes into a pointed shape, and a space is formed between the cutting edges to allow the cut wire to pass through, so the rhombic cross-sectional shape of the cutting wire resists pressure from the blade surface, etc. Therefore, there is no risk of plastic deformation.

Since the rolled wire is formed into a rhombic cross-sectional shape by cutting, the cross-sectional shape is maintained even after cutting and even when the rolled wire is boiled.

(Example) Hereinafter, an example embodying the present invention will be described in detail with reference to the drawings.

There is a noodle strip W on the top of the machine body 1 of the noodle strip shredding device S.
a pair of feed rollers 2L for adjusting the thickness of the
2R is rotatably mounted horizontally, and both feed rollers 2L, 2
Below R, a pair of vertical cutter rollers 4L and 4R are rotatable and horizontal, dividing the noodle strip W whose thickness is adjusted into six in the width direction of the same noodle strip W, and distributing the divided noodle strips W alternately. The rotation of a pulley 3, which is rotationally driven by a motor M1, is transmitted to the feeding rollers 2L, 2R and the vertical cutter rollers 4L, 4R. An inverted V-shaped guide plate 5 for guiding the divided noodle strip W is installed below the vertical cutter rollers 4L, 4R, and the top of the guide plate 5 is opposed to the vertical cutter rollers 4L, 4R.

The guide plate 5 has a plurality of (three in this example) guide surfaces 5a to 5a that tilt downward toward the left in the figure, and a plurality of guide surfaces (three in this example) that tilt downward toward the right in the figure. Guide surfaces 5a to 5a are respectively formed, and the guide surfaces 5a to 5a on both sides are connected in a substantially sawtooth shape via connecting surfaces 5b to 5b, respectively, and are formed in opposite directions and staggered.

Each pair of shredding rollers 6 to 6, each formed in a substantially conical shape, is mounted on two pairs of roller shafts 6a, 6a, which are rotatably suspended horizontally between the machine body 1, facing the lower end of the guide plate 5, respectively. They are fitted with a gap between them, and are arranged oppositely so that the small diameter side and the large diameter side face each other. The pair of shredding rollers 6, 6 on the left side and the pair of shredding rollers 6, 6 on the right side are respectively arranged in a staggered manner.

Each cutting roller 6 has cutting edge circles 7a to 7 on its outer periphery.
Blades 7 to 7 groups are arranged so that the diameter of a gradually increases and decreases, and each pair of left and right shredding rollers 6 to 6 has opposing cutting edge circles 7a, 7a.
are arranged in parallel so that they are facing each other (second
(see figure).

As shown in FIG. 3, each blade 7 has a pair of thin pointed cutting edges 7C projecting in a direction perpendicular to the roller shaft 6a. Therefore, the cutting edge portion 7C
The protruding direction is inclined by a predetermined angle with respect to the tangent L of both shredding rollers 6, 6 as shown in the figure, and the blade surface 7A of each blade 7 is inclined with respect to the roller axis a of the shredding roller 6, respectively. formed at right angles.

First grooves 8a to 8a are circumferentially formed near the tip of each blade 7, and a groove width equal to the thickness of the blade 7 is formed between the blade surfaces 7A to 7A of each blade 7. Second grooves 8b to 8b are circumferentially surrounded. Each first groove 8a of one shredding roller 6 and each second groove 8b of the other shredding roller 6 are opposed to each other (see FIG. 3),
As shown in the figure, a space of a predetermined size is formed by both the grooves 8a and 8b.

The belt conveyor 9 is disposed below the shredding rollers 6, 6, and the belt conveyor 9 has a conveyor belt 9a on the flow end side (the right side in FIG. 1) that guides the rolled wire W downward. A horizontal cutter roller 11 for cutting the rolled wire W into predetermined lengths is installed via a wall body 10. The cut wire W is cut by the horizontal cutter roller 11 at the lower part of the machine body 1.
It is carried out from the outlet 12 provided at the end of the outlet guide wall 13 erected below.

Next, the operation of the embodiment configured as described above will be explained.

First, the thickness is adjusted by the feed rollers 2L and 2R, and the noodle strip W fed from the feed rollers 2L and 2R hangs down due to its own weight and is fed between the vertical cutter rollers 4L and 4R. The vertical cutter rollers 4L and 4R divide the guide plate 5 into left and right alternately.
It flows down along the left and right guide surfaces 5a, 5a, respectively, and is sent between each pair of shredding rollers 6, 6. When the strip W is slit by the opposing blades 7, 7, it passes between the shredding rollers 6, 6 along the tangent L in an inclined state with respect to the roller axis a, as described above. It is diagonally cut by opposing cutting edge portions 7C that are protruded at a predetermined angle with respect to the tangent line L, and is formed into a rhombic cross-sectional shape.

Since the cutting edge part 7C is formed into a thin pointed shape, the cut wire W cut into a rhombic cross-sectional shape does not undergo plastic deformation due to the pressing force on the cutting edge part 7C, and the double concave groove 8a, It passes through the space between 8b.

Since each of the slit wires W is originally cut into a rhombic cross-sectional shape, it does not deform even after being shredded or boiled, and can maintain its deformed cross-sectional shape.

(Effect of the invention) This invention has the effect of cutting the mentai diagonally.
It is possible to obtain a wire having a rhombic cross-sectional shape, and the cross-sectional shape can be maintained even after being shredded or boiled.
