Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a blowfish skin thorn removal machine.

Conventional technology When cooking blowfish, the peeled skin is separated into a thick skin with thorns (outer skin) and a thin skin (inner skin). The thorns are removed with the tip of a knife, then washed and soaked in hot water before eating, making it a favorite among foodies. Removing thorns from thick skin requires a lot of effort and advanced technique, and the cutting edge tends to get worn out, so it has to be polished many times. Therefore, the applicant developed a device that deploys and locks the thick skin of blowfish on a guiding cart and cuts the thorns using a cutting blade that reciprocates in a direction perpendicular to the direction of movement of the guiding cart, or a rotating cutter. They developed and filed an application for a device that cuts splinters by deploying thick skin on a drum and using it in combination with a rotating cutter.

Problems to be Solved by the Invention However, the guide cart requires a wide space for its reciprocating operation, and the rotary cutter may cut the surface skin deeply along with the thick skin thorns. It was easy to cut and the cutting debris could easily fly off.

In order to solve these problems, the present invention is a stripping machine that combines a rotating drum that spreads and locks thick skin and a cutting blade that reciprocates in a direction perpendicular to the rotation direction of the rotating drum. It is characterized by the fact that cutting chips do not fly away, the cutting thickness is constant and thin, and it is small and easy to transport.

Means for Solving the Problems Hereinafter, the configuration of the present invention will be explained with reference to the drawings.

As shown in the front center vertical cross-sectional view of FIG. 1, the rotating drum 1 has a groove 2 parallel to the axis of the drum on its outer peripheral surface, and screw shafts 3, located near both ends of the inner wall surface of the front part of the groove 2. 3 is installed protrudingly. A holding plate 4 provided with a screw hole that fits into the screw shafts 3, 3 is inserted into the screw shafts 3, 3. A knob nut 5, 5 is screwed onto the screw shafts 3, 3 to lock one end of the blowfish skin between the front inner wall surface of the groove 2 and the presser plate 4.

As shown in the front view of FIG. 2 and the plan view of FIG. are doing. The shaft 9 is interlocked with a drum motor 11 installed on a pedestal 10 protruding from the outer surface of the right side plate.

As shown in FIG. 3, a cutting blade motor 22 is secured to a pedestal 21 protruding from the lower end of the right bearing plate 18. The crank disk 23 provided on the rotating shaft of the cutting blade motor 22 and one end of the front support rod 15 are loosely connected by a connecting rod 24, and the upper part of the rotating drum 1 is connected via the support rod 15 and the mounting plate 14. The cutting edges 13 of the cutting blades 12 are opposed to each other at the rear position so as to be guided back and forth in the left and right direction.

Further, screw bearings 25, 25 are provided to protrude outward from the upper ends of the left and right guide plates 16, 16. Adjustment bolts 26, 26 with knobs for vertically adjusting the left and right bearing plates 18, 18 are screwed onto the screw bearings 25, 25, and their lower ends abut against the upper ends of the left and right bearing plates 18, 18. The adjusting bolts 26, 26 with knobs also adjust the cutting edge 1 of the cutting blade 12 via the left and right bearing plates 18, 18.
3 and the rotating drum 1 is adjusted.

As shown in Fig. 1 and Fig. 3, the left and right side plates 7, 7
Bearings 27, 27 are provided at positions corresponding to the upper part of the rotating drum 1 on the inner surface of the rotary drum 1. The bearings 27, 2
7, left and right hanging shafts 28 fitted with springs at their lower ends;
28 is pivotally supported. A front press roller 29 is mounted on the lower ends of the left and right hanging shafts 28, 28. Bearings 30, 30 are provided on the left and right side plates 7, 7 corresponding to the lower part of the mounting plate 14 of the cutting blade 12. The bearings 30, 30 pivotally support horizontal shafts 31, 31 each having a spring fitted at its tip. A rear presser roller 3 is provided at the tip of the horizontal shafts 31, 31.
2 constitutes a blowfish skin stripping machine 33 which is mounted on a shaft. In the figure, 34 indicates blowfish skin, 35 indicates a front cover plate, and 36 indicates a rear side plate.

Function In the blowfish skin stripping machine 33 according to the present invention,
Loosen the adjustment bolts 19, 19 of the left and right bearing plates 18, 18, and rotate the adjustment bolts 26, 26 with knobs counterclockwise to raise them slightly.
The cutting edge 13 of the cutting blade 12 is separated from the outer peripheral surface of the rotating drum 1 by sliding it upward, and then the butt part of the thick skin 34 of the blowfish is held between the front wall of the groove 2 and the holding plate 4. After being attached and locked, the thick skin 34 is spread on the front surface of the rotating drum 1. and,
Rotating drum 1 is manually rotated backwards to remove cutting blade 12.
Adjust the left and right bearing plates 18, 18 downward while rotating the adjusting bolts 26, 26 with knobs clockwise, and after setting the position of the cutting edge 13, adjust the adjusting bolts 19, 19. Tighten the left and right bearing plates 18, 18 to the left and right guide plates 16, 16.
It is to be tightened. So, turn on the start switch
When turned ON, the cutting blade motor 22 rotates at high speed and the drum motor 11 rotates at low speed, and the rotation of the crank disc 23 of the cutting blade motor 22 causes the support rods 15, 15 to move left and right through the connecting rod 24. The cutting blade 12 reciprocates back and forth, and the cutting blade 12 reciprocates left and right at high speed together with the mounting plate 14 fixed to the support rods 15, 15, and the rotary drum 1 rotates at a low speed as shown by the arrow in FIG.
The thick skin 34 spread on the outer peripheral surface of the rotating drum 1 is pressed by the front pressing roller 29, and the cutting edge 13 of the cutting blade 12 is in contact with the surface of the thick skin 34 while pushing the thick skin 0.1 to 0.3 mm from the upper surface. It is about the same thickness as the thorns and cuts together with the thorns. The thick skin 34 is cut by the cutting edge 13 while the front and back positions of the cutting edge 13 are pressed by the front presser roller 29 and the rear pressing roller 32. Therefore, even if the cutting edge 13 moves back and forth, the thick skin 34 remains on the rotating drum 1.
When the thick skin 34 with the thorns cut out rotates to the front again without slipping from the surface, the switch is turned OFF and the rotating drum 1 and the cutting blade 12 stop, which means loosening the nuts 5, 5. The thick skin that has been cut is removed, a new thick skin is attached, and the cutting operation is started again.

Effects As mentioned above, in the present invention, the rotating drum 1
By combining this with the reciprocating cutting blade 12, the chips from cutting the thick skin 34 of the blowfish do not fly away, and the chips accumulated on the top surface of the cutting blade 12 fall one after another onto the top surface of the substrate 6. , shall be disposed of in a timely manner. Since the thick skin is guided by the rotating drum 1, it does not require space compared to a guiding cart, the thickness to be cut is thin and constant, and the shape is compact and convenient for transportation. This produces the remarkable effects described above.
