Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dry fish butterfly opening machine that splits dried fish, especially dried sub-ice fish pollock cod, etc., and pushes it open like a butterfly.

Generally, only the head and internal organs are removed, and the animal is dried naturally or by using a hot air dryer.

However, as ice fish and Alaska pollack dry, their entire bodies become wavy or curved, so they are shaped into straight shapes using shaping rollers, and then these ice fish and Alaska pollack are processed by hand (cottage industry). , using a specially shaped knife to tear pieces of ice fish, walleye pollock, etc., stacked on top of each other, then folded and pressed open like a butterfly.

Dried fish processed in this way is done by hand, which does not increase the production volume and is inefficient, and the processing fee increases year by year, resulting in high costs.

In addition, since it is impossible to mass-produce it by hand, it becomes an expensive dry fish and hinders its widespread use.

In addition, during manual processing, fish bones can cause injuries, which poses a safety problem.

The technical problem of the present invention is that dry fish such as sub-ice fish and pollock are automatically torn apart by a rotating cutter, and then the torn dry fish is automatically pushed open like a butterfly by 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 drive pulley and a guide pulley are arranged parallel to each other at a required distance from the front and rear of the base plate, and a clamping belt is hung between the pulleys. A pair of pressure automatic centripetal rollers are disposed sandwiching the clamping belt from the left and right in order to spread the fish, and are arranged at right angles to the traveling direction of the clamping belt so that the center of the dried fish between the clamping belts is torn in the direction of the fish axis. A rotary cutter is attached to the provided shaft, the lower part of the rotary cutter is located between the left and right gripping belts, the rear of the rotary cutter is approximately between the pressure automatic centripetal rollers, and the front of the rotary cutter is located between the left and right gripping belts. A pressure receiving roller is disposed on the side of a pressure roller attached to a shaft disposed perpendicularly to the traveling direction of the belt, and is disposed parallel to the axis of the pressing roller and directly below it. The protrusion of the pressure roller is fitted into the recess of the pressure roller.

The above technical means works as follows.

The dry fish that travels while being held between the left and right holding belts has a splitting function in which the center is torn straight in the direction of the fish axis by a rotating cutter that can move up and down, and the opening side of the torn dry fish is cut in the annular shape of a pressing roller. At the same time as the dried fish is pressed by the protrusion, the annular recess of the pressure receiving roller disposed opposite to the pressure roller supports the back side of the dried fish and sends it to the chute side.
Uniform pressing force acts on the abdomen side and dorsal side of the dried fish, and the function of pushing the fish open like a butterfly with its wings spread can be combined with one machine.

Then, since the pressure is automatically centripeted depending on the size (thickness or thinness) of the dry fish, the dry fish is 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 dried fish, it has an exceptional effect in that the dried fish can always be torn to an appropriate depth regardless of its size.

Furthermore, the dried fish is simply fed between the clamping belts from the table and is automatically torn and butterfly-opened, which has the effect of increasing production and reducing processing costs.

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

The butterfly opening machine of the present invention is comprised of a prime mover side A and a butterfly opening mechanism B on the left and right sides of an L-shaped partition wall 10.

(See FIG. 7) Reference numeral 50 denotes a pressing roller rotatably fitted onto a shaft 55 disposed parallel to the axis of the rotary cutter 12. The pressing roller 50 is used to spread the torn dried fish 51 left and right. It has a generally egg-shaped cross section, and a slit 52 into which a part of the rotary cutter 12 can be inserted is formed in the center, and a disc 53 is integrally formed on the side of the pressing roller 50. Spur gear 5
4 is installed.

Both ends of the shaft 55 of the pressing roller 50 are fitted and supported by receiving metals 56, 56, and a vertical screw shaft 5 is inserted into the through hole of the receiving metals 56, 56.

A roller located on the side that suppresses the spread of the clamping belts 40, 40, and can be replaced with a general rolling bearing.

72, 72 move forward and backward (loosen or tighten) to adjust the position of the guide pulleys 39, 39.
The support plate is fixed to the base plate 23 by screwing into adjustment bolts 41, 41, respectively.

Regarding the operation, when the dry fish 51 running while being held between the left and right holding belts 40 and 40 is torn by the rotating cutter 12 and sent between the pressure roller 50 and the pressure receiving roller 26, the dry fish 51 is separated between the rotating pressure receiving roller 26 and the pressure roller 50. The torn dried fish is pressed on the open abdominal side by the annular protrusion of the pressing roller 50, and at the same time, the annular recess of the pressure receiving roller supports it from the back side and sends the dried fish out to the chute side.

Therefore, a uniform pressing force acts on the open abdominal side and dorsal side of the dried fish, and the dried fish is pushed open like a butterfly with its wings spread.

Depending on the size and thickness of the dried fish, a pair of pressure automatic centripetal rollers automatically expand or contract 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 rotary cutter can be adjusted by operating the handle depending on the size of the dried fish, so the depth at which the dried fish is torn is appropriate, and the cutter does not split into two when the fish is opened.

In addition, the endless belt that clamps dried fish has an annular convex part on its inner surface, and a pair of drive pulleys and guide pulleys each have a concave part that matches the convex part, which prevents the clamping belt from moving up and down. I can do that.

In addition, in order to prevent contact between the running clamping belt and the rotating cutter, the automatic pressure centripetal roller has an approximately I-shaped cross section, so even if the lower side of the clamping belt is pressed from the left and right, a gap is formed on the upper side. , there was no belt damage during cracking of dried fish.
