Description

[Detailed description of the invention] Industrial field of application This invention is used to cut various fish flakes such as bonito flakes, mackerel flakes, and processed flakes made of fish or livestock meat shaped into stick-shaped bonito flakes. This cutting device is capable of cutting fish flakes as thin as possible (for example, 1/100 mm or less) and having a uniform thickness.

Prior Art It is desirable that bonito flakes be as thin as possible and uniform in thickness and shape in terms of meltability and texture when used in cooking. To cut thinly, it is necessary to prevent the rotating blade from swinging laterally during cutting.

In addition, kerifobushi is obtained by cutting the ikobushi, but in this case, the purpose of cutting the ikobushi is not to adjust the shape or dimensions of the ikobushi, but rather to obtain cut pieces, that is, kerifobushi. In addition, it is desirable to cut the kebushi as thinly as possible and to a uniform thickness, so in order to obtain the desired thin kebushi, the rotary cutter must be rotated at high speed to cut the kebushi. It must not be tilted, wobbling, or off-axis.

By the way, as shown in Figs. 1 and 2, a conventional bonito flakes cutting device for obtaining shaved bonito flakes has a plurality of planer blades c attached to a rotary plate b attached to a rotating shaft s, and rotates the rotary plate b. The bonito flakes A are pressed against the blade c to cut them.

Problems with the prior art However, in this cutting device, the plate-shaped planer blade c is not attached directly to the rotating shaft d, but is attached to a rotating plate b, and the rotating plate b is attached to the rotating shaft d. The mounting position of the rotating plate b may be eccentric or the rotating plate b may be distorted.
As a result, it is difficult for all of the planer blades c to contact the solid food A in a constant state, and therefore, there is a drawback that the thickness and shape of the cut pieces become non-uniform.

Furthermore, since it uses a planer blade c, there are various drawbacks as described below.

(1) Severe wear due to high cutting resistance. Therefore, in order to consistently cut the kerifubushi to a thickness of, for example, 2/100 mm, it is necessary to adjust the protrusion of the planer blade approximately every 10 minutes. To do this, it is necessary to stop the milling machine and stop the cutting operation, and the more the number of planer blades attached to the rotary plate, and the longer the length of the planer blades, the longer it takes to adjust. As a result, work efficiency and productivity are significantly reduced.

(3) If the planer blade is long, it is difficult to make it protrude uniformly over its entire length. As a result, the thickness and shape of the kerifobushi become uneven.

(4) If there are a large number of blades, only one blade may protrude extremely, resulting in uneven thickness and shape of the kerifobushi. In addition, the excessive force applied to the extremely protruding blade causes the disk to become distorted, making the thickness and shape of the karebushi even more uneven.

(4) Even if the person is an expert, the protrusion size of the blade is adjusted by intuition, so there is considerable variation in the adjustment time depending on the sharpening machine, and even more so, even if the person making the adjustment changes, it will be difficult to adjust the protrusion of the blade using the same sharpening machine. However, variations occur. As a result, the thickness of the cut pieces varies. The thickness of the shaved bushi currently on the market is 2/100 to 1
The reality is that it varies over a wide range of 0/100mm.

Purpose of the invention The purpose of the invention is to cut the dried bonito flakes as thinly as possible by rotating the rotary knife at high speed to cut the dried bonito flakes A by preventing the rotating knife from swinging sideways, wobbling, or misaligning. (for example, 1/100 mm or less), and also to be able to cut to a uniform thickness and uniform shape.

Means for Solving the Problems The fish cutting device of the present invention consists of a rotary blade 2 having shaft holes 1 and a rotary shaft 3 inserted into the shaft holes 1. A number of protruding blades 6 are formed on the outer circumferential surface so as to be oblique with respect to the axial direction, all or part of the protruding blades 6 are formed as intermittent cutting edges 5, and the shaft hole 1 is formed at the insertion end. A large-diameter portion 15 is formed in a tapered shape that gradually becomes thinner from the side to the tip end, and has a larger diameter than other parts of the shaft hole 1 in the longitudinal center of the shaft hole 1 and does not come into contact with the rotating shaft 3. The outer circumferential surface of the rotating shaft 3 is formed into a taper corresponding to the taper of the shaft hole 1, and a screw 20 for fixing the rotary cutter 2 is provided on the tip side of the rotating shaft 3.
A screw hole 19 is formed into which the screw is inserted.

Effect of the invention To use the device of the invention, the shaft hole 1 of the rotary cutter 2 is fitted onto the rotating shaft 3, and the nut 20 is screwed into the screw hole 19 of the rotating shaft 3 as shown in FIG. A rotary cutter 2 is fixed to a rotating shaft 3. In this state, the rotating shaft 3
is rotated to rotate the rotary cutter 2, and the bonito flakes A are pressed against the rotary cutter 2 from one end in the longitudinal direction as shown in FIG. 4B and FIG. 7B.

In this case, the shavings cut by the cutting blade 5 shown in Figs. 4 to 6 have the same width as the cutting blade 5 and a length of about 2 to 3 mm.
It becomes a strip about cm in size.

In the case of cutting with the rotary blade 2 shown in FIG. 7, a cut B is made in the cutter A by the cutting blade 12 as shown in FIG. 8, and then it is cut by the other protruding blade 6. The width of the scraping piece is cutting edge 1
The spacing is the same as in step 2, and the length is about 2 to 3 cm.

Embodiment The fish cutting device of the present invention comprises a rotary blade 2 having a shaft hole 1, and a rotary shaft 3 inserted into the shaft hole 1.

The rotary blade 2 has a number of protruding blades 6 formed on the outer peripheral surface of the base material 4 so as to be oblique to the axial direction thereof, and all or part of the protruding blades 6 are intermittently cut into the cutting blade 5.
is formed.

As an example of the rotary cutter 2 according to the present invention, the rotary cutter 2 shown in FIG. 5 is formed intermittently.

The rotary cutter 2 shown in FIG.
Cutting edges 5 are formed intermittently by providing a plurality of protruding cutouts 8 and providing notches 8 as shown in FIG.

The rotary cutter 2 shown in FIG. 6 has a plate-shaped small cutter 9 attached to the outer periphery of a cylindrical base material 4 having a shaft hole 1 with screws 10 or the like.

The rotary cutter 2 shown in FIG.
A plurality of protrusions are provided, the protrusion size of one of them 6x is larger than the protrusion size of the other protrusion blades 6, and the protrusion blades 6x are provided with equal intervals as shown in the figure C. A curved notch 11 is provided to form a sharp cutting edge 12.

The shaft hole 1 of each rotary cutter 2 is tapered to become gradually narrower from the insertion end 13 toward the tip 14, as clearly shown in FIG. Further, a large-diameter portion 15 is formed in the longitudinal center portion of the shaft hole 1, which has a larger diameter than the other portions and has a larger diameter so as not to contact the rotating shaft 3.

In addition, 16 in FIG. 4A, FIG. 5A, and FIG. 7A is a keyway. As clearly shown in FIG. 3, the rotating shaft 3 is tapered gradually from the insertion end 17 side to the tip end 18 side in correspondence with the shaft hole 1 of the rotary cutter 2, and has a screw hole 19 in the tip end 18. It will be opened.

Effects of the invention The fish cutting device of the invention has the following effects.

(1) Since the rotating blade 2 with the shaft hole 1 tapered is placed over the tapered rotating shaft 3, the rotating blade 2 can be securely attached to the rotating shaft 3. Therefore, even if the rotary cutter 2 is rotated at high speed to cut the fish A, the rotary cutter 2 will not oscillate laterally, wobble, or shift its axis. Therefore, the rotary blade 2 is always in constant contact with the solid food A, and the cut pieces are thin and have a uniform thickness.

(2) In addition to simply tapering the shaft hole 1, there is also a large diameter portion 15 in the longitudinal center of the shaft hole 1 that has a larger diameter than other parts of the shaft hole 1 so as not to contact the rotating shaft 3. As a result, the rotating shaft 3 is supported at two points in contact with only both sides of the large diameter portion 15 of the shaft hole 1. Therefore, even if there is some variation in the diameter of the shaft hole 1 or the outer diameter of the rotary shaft 3, the contact between the shaft hole 1 and the rotary shaft 3 is ensured, and lateral vibration, wobbling, and shaft misalignment occur when the rotary cutter 2 rotates. etc. are less likely to occur, and even thinner kerifobushi can be obtained.

(3) Since the screw hole 19 of the rotary shaft 3 is provided, the rotary cutter 2 can be fixed to the rotary shaft 3 by simply inserting the screw 20 into it, and conversely, the rotary cutter 2 can be fixed by simply removing the screw 20. It can be removed from the rotating shaft 3. Therefore, when the cutting blade 5 becomes worn or damaged, anyone can easily replace the rotary blade 2, whereas the planer blade shown in FIG. 1 can only be replaced by an experienced person.
There have never been any cases where the protrusion dimensions were uneven. Therefore, even if the rotary blade 2 is replaced, the cut pieces are thin and uniform in thickness, and there is no variation.

(4) As the rotary cutter 2, a number of protruding blades 6 are provided on the outer peripheral surface of the base material 4 so as to be oblique to the axial direction of the base material 4.
is formed, and all or part of the protruding blade 6 is formed as an intermittent cutting edge 5, so the drawbacks of the conventional planer blade are eliminated.

Furthermore, the synergistic effect of the above structure of the rotary cutter 2 and the fact that the rotary shaft 3 and the shaft hole 1 of the rotary cutter 2 are tapered and a large diameter portion 15 is formed in the longitudinal center of the shaft hole 1 allows fish to be Can be cut even thinner and with uniform thickness.
