[0044] The second set of extrusion devices is located between the third set of extrusion devices and the first set of extrusion devices.

[0045] The other end of the central shaft of the first driving wheel 10 is connected to the end of the shaft of the first gear positioning seat 8. The rotation of the driving gear 7 can drive the first driving wheel 10 to rotate. The other end of the central shaft of the second driving wheel 11 is connected to the end of the shaft of the second gear positioning seat. The rotation of the driven gear 9 can drive the second driving wheel 11 to rotate.

[0046] The first feed belt at the first driven pulley 14 and the second feed belt at the second driven pulley 15 form an inlet. The first feed belt at the first driving pulley 10 and the second feed belt at the second driving pulley 11 form an outlet.

[0047] The working process of the fish filleting machine described above is as follows:

[0048] refer to Figure 1 The feeding drive motor 5, the first blade drive motor 37, and the second blade drive motor 38 are started. The fish to be processed is placed at the inlet of the equipment. The support rail 32 provides support for the fish. The first feeding belt 12 and the second feeding belt 13 rotate. Driven by the first feeding belt 12 and the second feeding belt 13, the fish is fed according to... Figure 3 and 6The fish moves from right to left along the support track 32, between the first feeding belt 12 and the second feeding belt 13. When the fish passes the first set of extrusion devices, the left support 21-1 and the right support 21-2 open outwards, and the left extrusion wheel 18-1 and the right extrusion wheel 18-2 apply extrusion force under the tension of the tension spring 24, thus making the first feeding belt and the second feeding belt fit tightly against the fish. When the fish moves to the first set of extrusion devices, the left support 22-1 and the right support 22-2 open outwards, and the left extrusion wheel 19-1 and the right extrusion wheel 19-2 apply extrusion force under the tension of the tension spring 25, thus making the first feeding belt and the second feeding belt fit tightly against the fish. In this way, under the action of the first set of extrusion devices and the second set of extrusion devices, the first feeding belt and the second feeding belt can accommodate fish of different sizes.

[0049] As the fish continues to move forward, it reaches the first circular blade 39 and the second circular blade 40, where it is cut into three pieces: the middle piece is the fish bone, and the two side pieces are the fish meat. Thus, the fish is cut into two pieces of fish meat and one piece of fish bone. One piece of fish bone is located between the first circular blade 39 and the second circular blade 40, one piece of fish meat is located between the first circular blade 39 and the first feeding belt, and the other piece of fish meat is located between the second circular blade 40 and the second feeding belt. The left extrusion roller 30-1 and the right extrusion roller 30-2 in the third extrusion device apply extrusion pressure, ensuring that the two pieces of fish meat continue to move along with the first and second feeding belts under pressure, and are finally output from the outlet.

[0050] It is evident that the first and second feeding belts clamp the fish tightly during the fish transport process and can accommodate fish of different sizes.

[0051] It should be noted that the conveying device can also be connected to the frame 1.

[0052] It should be noted that the feeding drive motor 5 can also be connected to the drive gear 7 through other transmission mechanisms. The operation of the feeding drive motor 5 drives the drive gear 7 to rotate through the transmission mechanism.

[0053] To facilitate blade maintenance, the first blade drive device is installed as follows: a first motor bracket 41 and a first handle 43 are provided. The first motor bracket 41 is hinged to the rear side of the frame 1, and the first handle 43 is connected to the edge of the first motor bracket 41. The first blade drive motor 37 and the first transmission mechanism 45 are both mounted on the first motor bracket 41. Thus, when the first motor bracket 41 is moved, the first blade drive motor 37 and the first transmission mechanism 45 also move, and the first circular blade 39 is moved accordingly.

[0054] Similarly, the second blade drive device is installed in the same way: a second motor bracket 42 and a second handle 44 are provided. The second motor bracket 42 is hinged to the rear side of the frame 1, and the second handle 44 is connected to the edge of the second motor bracket 42. The second blade drive motor 38 and the second transmission mechanism 46 are both mounted on the second motor bracket 42. Thus, when the second motor bracket 42 is moved, the second blade drive motor 38 and the second transmission mechanism 46 also move, and the second circular blade 40 is moved.

[0055] In addition, a first motor cover 35 and a second motor cover 36 can be provided. The first motor cover 35 is mounted on the first motor bracket 41, and the second motor cover 36 is mounted on the second motor bracket 42.

[0056] To facilitate equipment maintenance, the connection structure between the central shaft of the first drive wheel 10 and the end of the shaft of the first gear positioning seat 8 can be a detachable connection, such as a detachable connection via a plug-in method. Similarly, the connection structure between the central shaft of the second drive wheel 11 and the end of the shaft of the second gear positioning seat can be a detachable connection, such as a detachable connection via a plug-in method.
