DETAILED DESCRIPTION

[0019] As Figures 1-4 shown, the bonito peeling device of the application includes a straight slide 1 and a discharge plate 3, the straight slide 1 is connected to an inclined slide 11 away from the discharge plate 3, a rotating disc 4 is installed between the straight slide and the discharge plate 3, a power flange 41 is connected to the center of the rotating disc 4, the rotating disc 4 makes intermittent motion, peeling rings 5 are uniformly distributed on the circumference of the rotating disc 4, and the peeling rings 5 are fixed on the rotating disc 4 by bolts. The peeling ring 5 includes a fixed ring 51, peeling mechanisms 52 are uniformly installed on the fixed ring 51, the peeling mechanism 52 includes a fixed base plate 521 installed on the fixed ring 51, the fixed base plate 521 is fixedly connected to a vertical plate 5211, a through hole 5212 is processed at the vertical plate 5211, a swing arm 524 is movably connected to the vertical plate 5211 through a rotating shaft 523, the swing arm 524 is installed at the vertical plate 5211, a spring 522 is installed at the side of the swing arm 524 away from the peeling knife 525, the peeling knife 525 is installed at the side of the swing arm 524 away from the peeling ring 5, the peeling knife 525 surrounds an oval shape, knife teeth 5251 are processed at the peeling knife 525, the knife teeth 5251 are serrated, and the shape of the oval surrounded by the peeling knife 525 matches the cross-sectional shape of the pectoral fin of the bonito 2.

[0020] The device utilizes the impact of bonito, and when passing through the space surrounded by the skinning knife, the knife teeth contact with the cooked bonito skin, so that most of the skin can be removed, the device is simple, and the skinning effect is good, and the device can replace the current manual skinning.

[0021] In use, for the convenience of understanding the present application, the description is made in combination with the accompanying drawings;

[0022] In work, the bonito enters the straight slide through the inclined slide, and passes through the skinning ring at a certain speed, and the knife teeth form an ellipse to wait for the bonito, since the shape of the knife teeth matches the cross-sectional shape of the chest fin of the bonito, the knife teeth enter the skin of the bonito, since the bonito has been cooked, the adhesion between the skin and the meat is small, the knife teeth act on the skin of the bonito to tear the skin, when the middle part of the fish body enters the hole surrounded by the skinning knife, the fish body passes through the hole with the increased cross-sectional area, the spring is compressed, the skinning knife opens outward, the fish body passes through, the spring resets, then the rotating disc rotates by an angle, the skinning ring with the skin rotates to the lower position to be cleaned, and the clean skinning ring is in place to wait for the next bonito to be skinned.

[0023] The above description is only the preferred embodiment of the present application, and is not used to limit the present application, and the present application can have various changes and variations for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
