The alignment shell 130 is arranged in the chassis 10. The bottom of the alignment shell 130 contacts the conveyor belt surface of the conveyor belt 110. Along the conveying direction of the conveyor belt 110, the port of the alignment shell 130 gradually narrows. The chassis 10 is provided with a device for processing the surimi. The extruding mechanism 30 is close to the conveying end of the conveyor belt 110. The chassis 10 is provided with a turning and flipping mechanism 20. The turning and flipping mechanism 20 is above the conveyor belt 110 and close to the discharge port of the squaring shell 130. The fish after being divided into two halves are put into the conveyor belt 110 in the chassis 10 through the feed hopper 120, and then the fish are squaring through the squaring shell 130 and moved to the turning and flipping mechanism 20, and then after being adjusted by the turning and flipping mechanism 20, they enter the extruding mechanism 30 for fish paste processing.

[0039] More specifically, the turning mechanism 20 includes a support plate 210, a motor 211, a connection cover 212, an image sensor 213, and a turning rod 214.

There are four rods 214 evenly arranged around the bottom of the connecting cover 212. The image sensor 213 is arranged on the wall of the connecting cover 212. The bottom of the turning rod 214 contacts the conveyor surface of the conveyor belt 110. When the fish is conveyed to the bottom of the connecting cover 212, if the image sensor 213 detects that the head of the fish is close to the conveying end of the conveyor belt 110, the motor 211 is started to drive the connecting cover 212 to rotate. When the connecting cover 212 rotates 180°, the turning rod 214 drives the head and tail of the fish to be swapped, so that the tail of the fish is close to the conveying end of the conveyor belt 110.

[0040] like Figure 3-Figure 8As shown, the turning and flipping mechanism 20 also includes a shift mechanism 220, a shift plate 1 221, a shift plate 222, a blanking plate 223, and a flipping assembly 240. The shift mechanism 220 (which is the prior art and will not be described in detail) is horizontally arranged on the wall of the connecting cover 212, the shift plate 1 221 is arranged at the end of the shift mechanism 220, the shift plate 222 is fixedly connected to the bottom of the shift plate 1 221, the shift plate 222 is horizontally arranged and contacts the conveyor belt surface of the conveyor belt 110, the blanking plate 223 is fixed to the end of the shift plate 222, the blanking plate 223 is inclined, the flipping assembly 240 is arranged opposite to the blanking plate 223, and the shift plate 1 221 is provided with a trigger assembly 230 for triggering the flipping assembly 240 to work.

[0041] More specifically, the trigger assembly 230 includes an air cylinder 231, an air pushing column 232, and an exhaust pipe 233. The air cylinder 231 is close to the wall of the connecting cover 212, and the air cylinder 231 is parallel to the shift plate 222. The air cylinder 231 is fixed to the wall of the connecting cover 212, one end of the air pushing column 232 is fixedly connected to the plate surface of the shift plate 1 221, and the other end of the air pushing column 232 is matched and extends into the air cylinder 231, one end of the exhaust pipe 233 is connected to the end of the air cylinder 231, and the other end of the exhaust pipe 233 is connected to the flip assembly 240. The exhaust pipe 233 is connected to a valve 234, and the valve 234 is close to the end of the air cylinder 231. The bottom of the valve 234 is matched and inserted with a baffle 235. In the initial state, the valve 234 is in an open state.

[0042] More specifically, a guide plate 250 is horizontally arranged on the plate surface of the shift plate 1 221, and the end of the guide plate 250 extends horizontally and is at the bottom of the baffle 235. A guide groove 251 is opened on the plate surface of the guide plate 250, and the guide groove 251 is close to the end of the guide plate 250. The guide groove 251 includes an inclined groove 1, a horizontal groove, and an inclined groove 2. The horizontal groove is between the inclined groove 1 and the inclined groove 2 and is at the bottom of the inclined groove 1 and the inclined groove 2. A guide column 236 is fixedly connected to the bottom of the baffle 235, and the guide column 236 is arranged horizontally. In the initial state, the guide column 236 matches the inclined groove 1 and is close to the top of the inclined groove 1. When the shift mechanism 220 drives the shift plate 1 221 to move in the direction close to the connecting cover 212 , the air-pushing column 232 moves in the air cylinder 231, thereby squeezing the gas in the air cylinder 231. When the guide plate 250 moves toward the direction close to the connecting cover 212, the guide groove 251 drives the guide column 236 to move downward, and the guide column 236 is in the horizontal groove of the guide groove 251. The baffle 235 moves downward, and the valve 234 is in a closed state. The gas in the air cylinder 231 is pressurized, and then the guide plate 250 continues to move toward the direction close to the connecting cover 212, and the guide column 236 is in the inclined groove 2 of the guide groove 251. The baffle 235 is reset, and the valve 234 is in an open state. The gas in the air cylinder 231 can be discharged to the flip assembly 240 through the exhaust pipe 233, thereby driving the flip assembly 240 to work.

[0043] like Figure 5 , Figure 8 As shown, the flip assembly 240 includes a connecting sleeve 241, a bearing plate 242, a push rod 243, and a top plate 244. Two connecting sleeves 241 are provided and arranged in parallel. One end of the connecting sleeve 241 is connected to the exhaust end of the exhaust pipe 233, and the other end of the connecting sleeve 241 is connected to the bottom of the bearing plate 242. The connecting sleeve 241 is arranged obliquely, and the bearing plate 242 is arranged obliquely. The bottom of the bearing plate 242 contacts the belt surface of the conveyor belt 110. The bearing plate 242 is arranged opposite to the blanking plate 223. The top plate 244 is matched and sleeved in the connecting sleeve 241 and is at the bottom of the connecting sleeve 241. The push rod One end of 243 is fixedly connected to the top plate 244, and the other end of the push rod 243 passes through the end of the connecting sleeve 241. An avoidance hole is opened on the plate surface of the supporting plate 242, and the end of the push rod 243 passes through the avoidance hole of the supporting plate 242. A spring is sleeved on the push rod 243, one end of the spring contacts the plate surface of the top plate 244, and the other end of the spring contacts the top inner wall of the connecting sleeve 241. The gas in the gas storage cylinder 231 can be discharged into the connecting sleeve 241 through the exhaust pipe 233, thereby pushing the top plate 244 to move, thereby driving the push rod 243 to be ejected through the plate surfaces of the gas storage cylinder 231 and the supporting plate 242.

[0044] like Figure 2 , Figure 9-10As shown, the extrusion mechanism 30 includes a mounting plate 310, an extrusion roller 1 320, a feeding belt 321, an extrusion roller 2 330, and a pressure ring 340. The mounting plate 310 is vertically arranged in the chassis 10, the pressure ring 340 is fixed in the chassis 10 and close to the conveying end of the conveyor belt 110, and an extrusion hole is opened on the ring surface of the pressure ring 340. The extrusion roller 1 320 and the extrusion roller 2 330 are rotatably mounted on the mounting plate 310. The extrusion roller 1 320 is driven by the motor 2 350 arranged on the mounting plate 310. The feeding belt 321 surrounds the extrusion roller 1 320 and the extrusion roller 2 330. The belt surface of the feeding belt 321 is arc-shaped and matches the pressing ring 340. The extrusion roller 1 320 and the extrusion roller 2 330 are close to the ring surface of the pressing ring 340. The extrusion roller 1 320 is close to the conveying end of the conveyor belt 110. After turning over, the fish meat faces upward and the fish skin faces downward, and the fish tail is close to the conveying end of the conveyor belt 110. Then the fish is conveyed between the feeding belt 321 and the pressing ring 340. The extrusion roller 1 320 squeezes the fish meat. After the fish meat is squeezed, it is formed into fish paste through the extrusion hole of the pressing ring 340. The fish paste falls into the pressing ring 340, and the fish bones and fish skin are conveyed and discharged through the feeding belt 321.

[0045] More specifically, a scraper 316 is provided in the chassis 10. The scraper 316 is located on the inner surface of the pressing ring 340. The bottom of the scraper 316 contacts the inner surface of the pressing ring 340. The scraper 316 is arranged at an angle so that the fish paste on the inner surface of the pressing ring 340 can be scraped and discharged.

[0046] More specifically, a discharge trough 140 is provided on the wall of the chassis 10, and a feed port of the discharge trough 140 is close to the second extrusion roller 330, so as to facilitate the discharge and collection of fish bones and fish skin discharged from the conveying end of the feeding belt 321.

[0047] Working principle:

[0048] During the use of the present invention, when the fish is transported to the bottom of the connection cover 212, if the image sensor 213 detects that the head of the fish is close to the conveying end of the conveyor belt 110, the motor 211 is started to drive the connection cover 212 to rotate. When the connection cover 212 rotates 180 degrees, the reversing rod 214 drives the head and tail of the fish to be reversed, so that the tail of the fish is close to the conveying end of the conveyor belt 110; when the fish is transported to the bottom of the connection cover 212, if the image sensor 213 detects that the fish meat is facing up and the fish skin is facing down, the shifting mechanism 22 0 drives the shift plate 1 221 to move toward the direction close to the connection cover 212, and the shift plate 222 pushes the fish to move and move to the inclined surface of the bearing plate 242, and the air push column 232 moves in the air storage cylinder 231, thereby squeezing the gas in the air storage cylinder 231. When the guide plate 250 moves toward the direction close to the connection cover 212, the guide groove 251 drives the guide column 236 to move downward, and the guide column 236 is in the horizontal groove of the guide groove 251, the baffle 235 moves downward, and the valve 234 is in a closed state. The gas in the air storage cylinder 231 The pressure is increased, and then the guide plate 250 continues to move toward the direction close to the connecting cover 212, the guide column 236 is in the inclined groove 2 of the guide groove 251, the baffle 235 is reset, and the valve 234 is in the open state. The gas in the gas storage cylinder 231 can be discharged into the connecting sleeve 241 through the exhaust pipe 233, thereby pushing the top plate 244 to move, thereby driving the push rod 243 to be ejected through the plate surface of the gas storage cylinder 231 and the supporting plate 242, thereby pushing the fish on the supporting plate 242 to turn over, and the turned fish is pushed to the blanking plate 223, and the fish is moved. The positioning mechanism 220 drives the blanking plate 223 to reset, and the fish slides onto the conveyor belt 110 through the blanking plate 223, thereby completing the turning over of the fish; after turning over, the fish meat faces upward, the fish skin faces downward, and the fish tail is close to the conveying end of the conveyor belt 110, and then the fish is conveyed to between the feeding belt 321 and the pressing ring 340, and the extrusion roller 320 squeezes the fish meat. After the fish meat is squeezed, it is formed into fish paste through the extrusion hole of the pressing ring 340, and the fish paste falls into the pressing ring 340, and the fish bones and fish skin are conveyed and discharged through the feeding belt 321.
