[0038] Working principle:

[0039] When in use, the peeled fish skin is spread on the convex plate 2233. Since the structure of the convex plate 2233 cooperates with the V-shaped groove 2223, it is a structure with a middle convexity. A knife groove 2234 is provided on the upper surface of the convex plate 2233, which can cooperate with the knife strip 2222 on the one hand, and is also used to prevent the fish skin from sliding on the other hand.

[0040] The water pump 301 is started by the controller 5, and the water valve 2 303 and the water valve 1 2123 are opened at the same time. The water pump 301 pumps water out, passes through the water supply pipe 1 2124 and the water supply pipe 1 2124 into the connecting pipe 2121, enters the water delivery pipe 2122 through the connecting pipe 2121, and flows out from the water outlet; then, the controller 5 controls the mobile motor to start, drives the mobile screw to rotate, drives the mobile block 1 2114 to move through the mobile screw, and drives the water delivery pipe 2122 to move by the mobile block 1 2114, so as to clean the fish skin, and the water flows into the water guide groove 2302 from both sides, enters the discharge groove 2301 through the water guide groove 2302, and receives the leaked water through the waste water tank 4.

[0041] After the cleaning is completed, the lifting electric cylinder 2211 is started by the controller 5, and the lifting electric cylinder 2211 drives the lifting plate 2212 to move downward, and the lifting plate 2212 drives the cutter plate 2221 and the knife strip 2222 to move downward, and the fish skin is cut by the knife strip 2222.

In this process, the water guide 2302 rotates downward with the bearing plate 2231, and the waste water in the water guide 2302 can be quickly introduced into the discharge tank 2301.

[0042] Then, the controller 5 controls the flipping motor 2241 to flip, and the flipping motor 2241 drives the tool plate 2221 to reverse to a horizontal state, and then continues to rotate, at which time the water guide groove 2302 drives the discharge groove 2301 to move, so that the discharge groove 2301 is higher than the collection groove 2403.
