Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tear-opening machine for tearing open fish, especially dried sub-ice fish such as pollock cod, and pushing it open like a butterfly.

Generally, one head and internal organs are removed and only the original part is dried naturally or using a method such as a hot air dryer.

On the other hand, ice fish such as walleye pollack become wavy or curved as they dry, so they are shaped into a straight shape using a shaping roller, and then these ice fish and walleye pollack are processed by hand (cottage industry). Then, using a specially shaped knife tube, we split several slices of ice fish, walleye pollock, etc., stacked on top of each other, then folded them and pushed them open like butterflies. ing.

Processing in this way is done by hand, which does not increase production volume and is inefficient, and also increases costs as processing fees rise year by year.

In addition, since mass production is impossible because it is done manually, it is an expensive process and hinders its widespread use.

In addition, injuries caused by fish bones during manual machining have become a safety issue.

``The technical problem of the present invention is to automatically tear pieces of fish such as sub-ice fish and pollock into a rotary cutter, and then automatically push the torn pieces open like a butterfly using upper and lower rollers. The purpose is to provide functions. The structure of the present invention, that is, the technical means for solving the above technical problem is as follows.

A pair of driving pulleys are arranged in parallel at the front and rear of the base plate, and a clamping belt is hooked on each guide pulley. a pressure automatic centripetal roller, a rotary cutter that splits the center of the dry fish in the fish axis force direction between the clamping belts pressed and centripeted by the pressure automatic centripetal roller, and a shaft disposed parallel to the rotary cutter axis. The rotating butterfly opening machine is comprised of a pressure roller attached thereto and a pressure receiving roller attached to a shaft disposed opposite to the pressure roller.

The above technical means work in the following ways.

The dry fish that travels between the left and right gripping belts is moved vertically by a rotary cutter, which has a tearing function in which the center is torn straight in the direction of the fish meal, and the dried fish that has been torn can be opened. At the same time, the back side of the dried fish is supported by the annular recess of the pressure receiving roller, which is disposed directly below the pressure roller, and the chute side is pressed by the annular projection of the pressure roller. In order to feed the dried fish, a uniform pressing force is applied to the open abdominal side and dorsal side of the dried fish, and it has the function of pushing the fish open like a butterfly with its wings spread, and has two functions in one machine. can be set.

Since the dry fish is automatically compressed and centripeted depending on the size (thickness or thinness) of the dry fish, the dry fish can be opened straight.

In addition, since the rotary cutter can be adjusted to be able to move up and down depending on the size of the dry fish, it has an exceptional effect in that the dry fish can always be torn to the appropriate depth regardless of the size of the torn fish.

In addition, the dried fish is automatically torn and opened by simply feeding it between the table and the clamping belt, which has the effect of increasing production and reducing processing costs.

Next, an embodiment of the technical means of the present invention will be explained based on the drawings.

About the action.

The rolling pin 51 running while being held between the left and right holding belts 40 and 40 is torn by the rotating counter 12 and fed between the pressure roller 50 and the pressure receiving roller 26, and is then rotated once by the pressure receiving roller 26 and the pressure □ The torn tip between the rollers 50 is pressed by the annular protrusion of the suppressing roller 50 from the abdominal side, and at the same time, the annular circumference S of the pressure receiving roller supports the dorsal side and shoots the tip. Send it to the side.

Therefore, a uniform pressing force acts on the open abdominal side and the dorsal side of the tip, pushing them open like a butterfly with one wing spread out.

Depending on the size and thickness of the dried fish, a pair of pressure automatic centripetal rollers automatically expands or contracts left and right via a pair of gears, so the dried fish is always held between the clamping belts with a constant pressure. , the abdomen is opened directly. In addition, the height of the υ rotary cutter can be adjusted by operating the nozzle depending on the size of the dried fish, so the depth at which the dried fish is torn is adjusted to the appropriate depth, and the fish will not be split into two when separating the lines.

In addition, the endless belt that clamps dry fish has an annular convex S on its inner surface, and concave S that corresponds to the convex are formed on each of the pair of drive pulley and guide pulley, so that the vertical movement of the clamping belt is prevented. It can be prevented.

In addition, in order to prevent contact between the running clamping belt and the rotating cutter, the shape of the automatic pressure centripetal roller is approximately I-shaped in cross section. There was no belt damage during the formation and roll tear.
