Description

Technical Field

[0001] The invention relates to the technical field of aquatic product primary processing machinery, in particular to an adjustment mechanism for a fish machine with eight blades and three starts. Background Art

[0002] With the development of the aquatic product processing industry and the increase in labor costs, the gradual reduction of the labor force has put forward the demand for mechanization in fisheries. High-quality and efficient mechanized processing has become an inevitable requirement. Therefore, the research and development of key technologies and equipment for aquatic product processing to achieve high-quality and efficient production of aquatic products is of great practical significance.

[0003] Cutting is a key step in the primary processing of fish, primarily involving dorsal and ventral cuts, as well as splitting into two or three pieces. Cutting the fish body produces fillets, facilitating subsequent processing. Domestic research on fish cutting technology primarily focuses on dorsal and ventral cuts. Huazhong Agricultural University has developed chain-type fish cutters and belt-type, clamp-feed freshwater fish cutters, enabling freshwater fish cuts and gutting. To reduce fish meat damage and increase visceral removal rates during the gutting process, the Fisheries Machinery and Instrument Research Institute conducted experimental research on optimizing cutting tools for horse mackerel gutting. Currently, research on splitting into three pieces of fish is limited in China, and no practical equipment has been developed. Research on multifunctional cutting technology is underway internationally. Japan has developed the FSS series of cutters, which can perform dorsal, dorsal, split into two pieces, and split into three pieces. However, splitting into three pieces presents significant fish meat loss.

[0004] Therefore, the high meat yield of three-piece opening is a difficulty in the primary processing of fish. There are problems such as lack of key equipment, large fish meat loss, and low meat yield. The market needs practical equipment that can reduce fish meat loss, increase fish meat yield, and have strong adaptability.

The feeding mechanism 5 and the feeding posture maintaining mechanism 6 cooperate with each other to press and limit the fish meat to maintain the posture of the fish body when moving.

[0044] There are two conveying mechanisms 7, which are installed on both sides of the frame 1, and the feeding mechanism 5 is located in the middle of the conveying mechanism 7. The conveying mechanism 7 is used to clamp the fish body for movement; multiple free adjustment mechanisms 3 are symmetrically installed on one side of the two frames 2, and a first driving member 41 is rotatably installed on one side of the free adjustment mechanism 3. The first driving member 41 is a vertical motor. The output end of the vertical motor is connected to the knife shaft, and the other end of the knife shaft is installed at the central axis of the cutting knife 4. The vertical motor drives the cutting knife 4 to rotate.

[0045] The free adjustment mechanism 3 adjusts the position angle of the cutting knife 4 in multiple directions, and the vertical motor drives the cutting knife 4 to rotate to cut the fish body.

[0046] The beneficial effects obtained by the frame 1, two frames 2, multiple free adjustment mechanisms 3, multiple cutting knives 4, feeding mechanism 5, feeding posture maintaining mechanism 6 and conveying mechanism 7 are as follows: the free adjustment mechanism 3 can adjust the five degrees of freedom of the cutting knife 4, thereby realizing position adjustment of the cutting knife 4 in the X, Y and Z axis directions and angle adjustment in the X and Z axis directions, thereby achieving the effect of multi-directional and accurate adjustment of the parameters of the cutting knife 4, and improving the adaptability and reliability of the cutting knife 4.

The threaded adjustment rod 54 is threadedly installed on the bottom of the bracket 53, and the guide groove 55 is installed on the top of the bracket 53. When the threaded adjustment rod 54 is turned, the threaded adjustment rod 54 drives the bracket 53 to move vertically up and down, and the guide groove 55 follows the bracket 53 to move up and down, thereby achieving adjustment according to the width and height of the fish body.

Depending on the size of the fish, and during the backward conveying process of the fish, the upward thrust of the two pressing plates 65 is different at different positions of the fish. The two pressing plates 65 can be changed in position according to the shape and adjusted to a suitable height to ensure the conveying posture of the fish. The side shape of the two pressing plates 65 is based on the external structure and size of the fish spine and abdominal cavity, and adopts a long strip shape with a pointed mouth on the left and a circular arc on the right.
