The working principle is as follows:

(1) the driving mechanism drives one of the chain wheels 16 to rotate, and then drives the chain 110 to rotate by means of the other chain wheel 16; when each hang and establish subassembly 19 and flow to the below, insert arc 132 and the one end of stay 14 all in the fish mouth to with the help of a plurality of sword tooth 11 chucking inside the fish head, compress tightly the outside of fish head with the help of bending section 121 simultaneously and prevent it and drop, thereby fix the fish on hanging establishing subassembly 19 and continue the circulation in order to transport next process position department with the help of the fish head.

(2) When a fish moves to the straightening mechanism 2, the fish head firstly passes through the two clamping plates 23 and then enters between the two clamping feet 21, the width of the fish head is larger than the distance between the two clamping feet 21, the two clamping feet 21 are unfolded to stretch the two fifth tension springs 29, and then the fish head is clamped by the resilience of the two fifth tension springs 29, as long as one clamping foot 21 is unfolded, the clamping foot 21 drives the first rotating shaft 211 and the first traction plate 213 to rotate by virtue of the first supporting arm 22, and further drives the other first supporting arm 22 and the clamping foot 21 to unfold by the same angle by virtue of the meshing connection relationship of the two first fan-shaped tooth sheets 212 and the other first traction plate 213, so that the symmetrical clamping is realized; the fish body enters between the two clamping plates 23, the two clamping plates 23 are outwards spread, the fourth tension spring 28 is stretched, the two clamping plates 23 clamp the fish body by means of the resilience of the fourth tension spring 28, and therefore straightening of the fish body is achieved; as long as one of the clamping plates 23 is spread, the clamping plate 23 will drive the second rotating shaft 210 to rotate in the second shaft sleeve 26 by means of the second supporting arm 24, and then drive the second traction plate 27 to rotate, so that the other second supporting arm 24 and the clamping plate 23 are also spread by the same angle by means of the meshing connection relationship of the two second fan-shaped teeth 25 and the other second traction plate 27, and thus, symmetrical clamping is realized.

(3) The straightened fish moves to the position above the belly cutting knife 3 under the driving of the transmission mechanism 1, the driving mechanism drives the belly cutting knife 3 to rotate so as to cut open the belly of the fish, the fish with the belly opened continuously moves to the position below the back cutting knife 4 under the driving of the transmission mechanism 1, and the driving mechanism drives the back cutting knife 4 to rotate so as to cut the fishbone on the back of the fish and separate the fishbone from the fish.

(4) The opened fish is driven by the transmission mechanism 1 to continue to move to the bone removing mechanism 5, the drive mechanism drives the input shaft 53 to rotate in the first shaft sleeve 515, and then drives the left output shaft 513 to rotate by means of the first bevel gear 512 and the fourth bevel gear 521, so as to drive the left third bevel gear 519 and the left blade 514 to rotate, and further drives the second transmission shaft 517 to rotate in the cabin 516 by means of the left second bevel gear 518, so as to rotate by means of the right second bevel gear 518, and further drives the right output shaft 513 to rotate by means of the right third bevel gear 519, so as to drive the right blade 514 to rotate; when the belly moves between the two blades 514, the bones of the belly are cut away from the bones of the back.

The fourth link 823 moves upward to drive the right end of the swing arm 825 and the back knife 4 connected to the right end of the swing arm 825 to swing upward and stretch the second tension spring 87 via the third connector 824, and when the roller 84 is disengaged from the cam 83, the right end of the swing arm 825 swings downward in the same manner, and the back knife 4 connected to the right end of the swing arm 825 swings downward under the action of the resilience of the second tension spring 87.

The up and down movement of the fifth link 834 drives the deboning mechanism 5 up and down via the fourth connector 832 and the traction sleeve 511, thereby adjusting the position of the two blades 514.

The upward movement of the sixth link 827 drives the left end of the swing seat 828 to swing upward via the fifth connector 830, and further drives the seventh link 829 to move upward to the right via the sixth connector 831, thereby driving the separation blade 6 to rise and stretching the third tension spring 836; when the sixth link 827 moves downward, the fifth link 830 will drive the left end of the swing seat 828 to swing downward, and the seventh link 829 will drive the separation blade 6 to move downward, so the resilience of the third tension spring 836 will accelerate the downward swing of the swing seat 828.

The fish cutting device can automatically complete feeding, laparotomy, back cutting and abdominal bone cutting of fish, greatly improve the fish slicing speed and work efficiency, reduce labor intensity, and avoid direct contact of an operator with a cutter and fish meat, thereby protecting the operator from injury and avoiding pollution to the fish meat; two clamping feet 21 and two clamping plates 23 in the straightening mechanism 2 are respectively and symmetrically used for clamping the fish head and the fish body so as to ensure the accurate positions of the abdominal cutter 3 and the back cutter 4; the deboning mechanism 5 improves deboning accuracy; the transmission mechanism 1 can firmly clamp the inside of the fish head, thereby effectively preventing the fish from loosening and even falling; the adjusting mechanism 8 can adjust the positions of the two blades 514 in the separating knife 6, the back cutting knife 4, the abdominal cutting knife 3 and the bone removing mechanism 5 according to different types of fishes, so that the invention has wider application range.
