Description

[Detailed description of the invention]

[0001]

Industrial Applicability The present invention is suitable for mass-cutting various types of fish knots such as fish knots such as bonito and saba-knots, or processed knots obtained by processing fish meat or animal meat into bonito flakes. The present invention relates to a device for adjusting the width of a cut-off node passage in a fish cut-off device.

[0002]

2. Description of the Related Art Sharp knots obtained by cutting fish knives are preferably soft so that they can be easily melted when they are contained in the mouth, and are easy to melt. For that purpose, the thinner the cut-knot, the better, and the pieces of fish-knots and shreds (remaining cut)
It is preferable that no such material is mixed.

Conventionally, a cutting device as shown in FIG. 17 has been considered as a cutting device for obtaining such a cut node. This is such that the fish segments A are transported in the direction of the arrow and pressed against the rotary blade B for cutting, so that the cut nodes C fly out of the cutting node passage G between the side wall F of the transfer path D and the rotary blade B. It was made.

[0004] In this case, if the shaving node path G is too wide, the fish knots A are caught between the path and the rotary knife during the cutting, and are crushed, or sway or vibrate due to the rotating force of the rotary knife B. It may become powder, cannot be cut thinly, cannot be cut to the end, and as a result, fragments or fish pieces of the fish knot A may fly out of the cut node passage G together with the cut node and enter the cut node. For this reason, the shaving node passage G
Is desired to be as narrow as possible.

Therefore, conventionally, the tip H of the side wall F and the rotary blade B are arranged so as to be as close as possible. However, there is a limit to the approach, and even if the approach is possible as much as possible, When the knots A are cut, the cutting of the rotary blade B becomes worse. If the blade of the rotary blade B is sharpened every time the cutting becomes bad, the blade is worn, the outer diameter of the rotary blade B becomes small, and the cutting node path G becomes wide.

In addition, since both the side wall F and the rotary blade B are fixed, even if the outer diameter of the rotary blade B becomes small, it is not possible to shift the positions of the rotary blade B to narrow the cutting node passage G. For this reason, in order to narrow the cutting node passage G, the rotary blade B must be replaced with a new one. However, since the outer diameter dimension of the rotary blade B varies strictly one by one, the width of the cutting path G varies even if the rotary blade B is replaced with a new rotary blade B.

Conventionally, to solve these problems, FIG.
A device for adjusting the width of the cut-off passage has been considered. This is because the distance adjusting body I is opposed to the outer peripheral surface side of the rotary blade B which cuts the fish segment A transferred on the transfer path from one end in the longitudinal direction thereof and cuts the same. Coordinator I
A cutting node path G through which the cutting node cut by the rotary blade B passes is formed between the rotary blade B and the space forming member I, which is rotated in the direction of the arrow in FIG. 8, moved toward the rotary blade B, or replaced. Thus, the width of the scraping node passage G can be adjusted.

[0008]

However, in the device for adjusting the width of the scraping passage shown in FIG. 18, the space adjusting member I is installed outside the transfer path D, so that there is a problem that the space is taken up and the structure becomes complicated. .

An object of the present invention is to provide an apparatus for adjusting the width of a shaving node passage in a fish segment cutting device which has a simple structure, requires no space for installation, and can easily adjust the width of the shaving node passage. is there.

[Effects of the Invention] The width adjusting device of the shaving passage in the fish knot cutting device of the present invention has the following effects. The width of the cut-off node passage K can be easily adjusted only by sliding the interval adjuster 3 back and forth in the transport direction of the fish segments A. Since the width of the cut-off node passage K can be easily narrowed, there is almost no possibility that fish knots are caught between the passage and the rotary blade, and are crushed, chipped, or clogged. It is difficult for them to come out, and it is difficult for them to be mixed into the cut nodes of good products. In addition, since the fish segments A can be cut during cutting, the yield can be improved. Further, since the remaining shavings of the fish knives A cut into the shaving node passage K during the cutting, the rotary blade B is hardly damaged, and the rotation of the rotary blade B is hardly stopped, so that continuous cutting becomes possible. Work efficiency is improved, and stable production of cut nodes, and inexpensive cut nodes can be provided. According to the width adjusting device of the sharpening node passage of claim 2, the protrusion 3c
The width of the cut node passage K can be freely changed without being restricted by the shape of the gap adjusting body 3 only by changing the shape, dimensions, and the like of the gap adjusting member 3. According to the width adjusting device of the sharpening passage, the interval between the sharpening passages K can be arbitrarily adjusted only by sliding the projection 3c. In the width adjusting device of the scraping passage according to the fourth aspect, the gap between the scraping passages K can be arbitrarily adjusted only by sliding the protrusion 3c without providing the interval adjusting body 3.
