The two driving wheels 16 used to drive the two conveyor belts 11 are driven by the bevel gear transmission component 41 to rotate, and the driving wheel 16 is fixed on the frame 5 by the roller base 12 and the limit block 13. The conveyor belt 11 is installed on the driving wheel 16 and the driven wheel at both ends of the frame 5, driven by the transmission motor 23, and the bevel gear transmission component 41 is connected to the driving wheel 16. The bottom of the two driving wheels 16 is connected to the bevel gear transmission component 41, and the bevel gear transmission component 41 is driven by two pairs of bevel gears. The transmission motor 23 provides power for the driving wheel 16, and the bevel gear transmission component 41 is connected to the output shaft of the transmission motor 23 through a coupling and driven by the transmission motor 23 to drive the fish conveying mechanism to operate. The fish supporting plate 15 is fixed in the center at the bottom between the two conveyor belts 11, the fish pressing plate 6 is arranged between the two conveyor belts 11, and the fish pressing plate 6 is installed above the fish body conveying mechanism to prevent the head and tail of the fish body from curling up during processing. The fish pressing plate 6 is provided with a threaded hole, and the fish pressing plate 6 is fixed above the frame 5 by the fish pressing plate fastening bolts 7 and the threaded hole. The fish pressing plate 6 is fixed in the vertical direction slightly above the top of the driving wheel 16, and is fixed in the horizontal direction between the two conveyor belts 11. A conveying channel for conveying fish bodies 40 is formed between the two conveyor belts 11.

[0031] Specifically, the fish body 40 is conveyed forward by the conveyor belt 11, and the initial conveying spacing of the fish body 40 can be adjusted by moving the roller base 12 to ensure the normal introduction of the fish body 40. The driven wheel of the fish body conveying mechanism is fixed to the frame 5 by the limit block below. The conveyor belt 11 is sleeved between the driving wheel 16 and the driven wheel, and the driving wheel 16 is connected to the bevel gear transmission component 41 to ensure the smooth operation of the conveyor belt 11, wherein the fish body to be processed is located between the two conveyor belts 11.

The two triangular connecting pieces 24 with teeth are symmetrically opened and closed under the action of the tension spring 19. The clamping adjustment mechanism 17 is fixed to the crossbeam 21 of the frame 5 through the mounting plate 25 and the fastening screws 20. The multiple clamping adjustment mechanisms 17 press the conveyor belts on the inner sides of the two conveyor belts 11, so that the fish body 40 is closely attached to the conveyor belt 11, ensuring that there is no slipping during the conveying process.

[0033] The structure of the conveyor belt tensioning adjustment mechanism 18 is similar to that of the clamping adjustment mechanism 17. The clamping roller 28 is pressed against the conveyor belts outside the two conveyor belts 11 by the tension spring 19, so that the conveyor belts 11 are kept in a tensioned state to ensure the overall transmission efficiency.

[0034] like Figure 1 , Figure 6 , Figure 7 As shown, the fish body cutting mechanism includes a cutting transmission component and a fish body cutting component 22.

The cutting transmission component transmits the power of the cutting motor 1 through the driving pulley 2, and the power is transmitted to the driven pulley 3 through the transmission belt. The power is transmitted to the driving pulley 35 coaxially arranged with the driven pulley 3 through the rotating shaft installed on the pulley bearing 39, and then transmitted to the cutter disc driving pulley 37 by the transmission belt 36. The tensioning pulley 8 maintains the tension of the transmission belt 36 to ensure the overall transmission efficiency. The cutter disc drive pulley 37 is fixedly mounted on the cutter disc shaft 30, and the cutter disc drive pulley 37 drives the cutter disc shaft 30 to rotate, thereby driving the cutting cutter disc 10 to rotate. The cutting transmission component connects multiple pulleys through a transmission belt, and the tensioning wheel 8 adjusts the transmission belt tension to ensure stable transmission.

[0035] The fish body cutting component 22 is located on one side above the frame 5, and is connected to the fish body transmission component through a transmission belt to drive the cutting disc 30 to rotate. Specifically, the fish body cutting component 22 includes a lead screw 29 rotatably mounted on the frame 5, a disc shaft 30, a bearing seat 31, a lifting slider 32 connected to the frame 5 and sliding up and down, a twisting part 33 fixed on the top of the lead screw 29, and a bearing 34 installed in the bearing seat 31.

Among them, the lifting slider 32 and the lead screw 29 are connected to the threaded part of the lead screw 29 and the threaded hole on the lifting slider 32. The lead screw 29 can rotate relative to the frame 5 but cannot move up and down. The depth adjustment of the fish body cutting component 22 is achieved by twisting the twisting part 33 to drive the lead screw 29 to rotate, thereby adjusting the up and down movement of the lifting slider 32. At the same time, the cutter disc drive pulley 37 fixed on one side of the cutter disc shaft 30 cooperates with the tensioning wheel 8 to adjust the tension state of the drive belt 36, thereby adjusting the required cutting height of the fish body. The fish body cutting component is located on one side of the frame 5, and the lifting slider 32 is adjusted to move up and down by rotating the lead screw 29. The lifting slider 32 moves up and down under the adjustment of the lead screw 29, and the fish body cutting component 22 realizes the lifting and lowering adjustment of the cutting cutter disc 30 through the tensioning wheel 8 and the lifting slider 32.

[0036] The cleaning mechanism includes a plurality of high-pressure nozzles 9 and a sewage collecting component 14 installed on the frame 5, and the high-pressure nozzles 9 are connected to the high-pressure water pump through a pipeline. The sewage collecting component 14 is fixed at an oblique downward angle below the frame 5.

[0037] Below, refer to Figures 1 to 7 Combined with the description of the above structural features, the working process of the clamping and conveying fish body cutting device of the utility model is briefly described:

[0038] The fish body conveying mechanism is started, and the staff puts the fish body 40 to be processed between the fish supporting plate 15 and the fish pressing plate 6, and the fish body 40 is placed in the center of the conveying channel. The two conveyor belts 11 clamp the fish body 40 under the action of the clamping adjustment mechanism 17 to realize the conveying process, and the fish body is introduced into the cutting processing position. The fish body cutting component 22 adjusts the lifting slider 32 by tightening the screwing part 33 according to the different body widths of the fish body 40, thereby realizing the height adjustment of the cutting disc 10. When the fish body 40 moves to the cutting disc 10, the cutting transmission component driven by the cutting motor 1 is transmitted to the cutting disc 10, and the back of the fish body 40 is completely cut open; during the cutting process, four high-pressure nozzles 9 rinse the stains on the fish body 40 and the cutting disc 10, and the sewage is discharged through the sewage collecting component 14; finally, the fish body 40 is transported to the fish outlet 4 by the conveyor belt 11, thereby completing the fish body cutting process.
