[0044] The working principle of the utility model of the automatic packaging device for frozen crayfish is as follows:

[0045] The automatic packaging system for frozen crayfish is used to load the frozen crayfish into tanks 71 for packaging. The automatic packaging system is located in a cold storage room to ensure that the frozen crayfish remain at a low temperature during the packaging process, thereby preserving their freshness. The frozen crayfish to be packaged are placed in a storage hopper 31.

[0046] When packaging, see Figure 1, the empty tank body 71 is conveyed forward along with the conveyor belt 2, and the disc 1 rotates intermittently in the clockwise direction. When the tank body 71 enters the arc notch 11 at position A, the arc notch 11 drives the tank body 71 to slide onto the surface of the arc-shaped supporting piece 82 and rotate clockwise along with the arc notch 11 along the arc-shaped guiding strip 81. The inner side of the arc-shaped guiding strip 81 abuts against the side wall of the tank body 71, keeping the tank body 71 within the arc notch 11.

[0047] When the empty tank body 71 is aligned with the discharge tube 35, the disc 1 stops rotating. Subsequently, the spiral blade 34 rotates several turns, conveying a certain quantity of frozen crayfish in the storage hopper 31 to the discharge tube 35 and then into the tank body 71. Immediately afterwards, the cutting shovel 361 moves forward to seal the discharge opening of the discharge tube 35 (refer to Figure 3 ).

[0048] Subsequently, the tank body 71 already filled with frozen crayfish continues to move along with the disc 1. When its tank opening is aligned with the notch of the cover body temporary storage groove 421, the disc 1 stops rotating. See Figure 4 , the cover body conveying device (not shown in the figure) used in conjunction with this automatic packaging device will intermittently feed the cover body 72 into the cover body temporary storage groove 421. The supporting convex strips 4211 provided at the bottom side edges of the two groove walls of the cover body temporary storage groove 421 jointly support the edge of the cover body 72 to temporarily store the cover body 72. When the tank opening of the tank body 71 already filled with frozen crayfish is aligned with the notch of the cover body temporary storage groove 421, the cover body placing vertical sliding seat 42 moves downwards so that the cover body 72 slightly covers the tank opening of the tank body 71. Subsequently, the cover body pushing air cylinder 43 pushes the cover body 72 downwards out of the cover body temporary storage groove 421 (when being pushed out, the cover body 72 undergoes elastic deformation), enabling the cover body 72 to be perfectly covered on the tank opening of the tank body 71. Subsequently, the cover body placing vertical sliding seat 42 moves upwards to reset.

[0049] Subsequently, the tank body 71 already covered with the cover body 72 continues to move along with the disc 1. When the tank body 71 moves to align the cover body 72 with the capping cover body 551, the capping vertical sliding seat 54 moves downwards, causing the capping cover body 551 to contact the cover body 72. Subsequently, the capping air cylinder 55 presses the cover body 72 downwards and maintains the pressure for a period of time, so that the snap ring (not shown in the figure) on the inner wall edge of the cover body 72 is pressed into the annular slot on the outer wall edge of the opening of the tank body 71, achieving the sealed capping of the cover body 72.

[0050] The automatic packaging device for frozen crayfish of the present utility model can automatically perform the processes of filling, capping, and sealing, enabling each process to be efficiently and seamlessly connected, thereby improving the packaging efficiency and ensuring the freshness of the crayfish. The canned frozen crayfish is protected by the tank body and can avoid being squeezed during transportation, which is beneficial to maintaining the texture of the crayfish. In addition, the filled crayfish can also avoid bacterial contamination, etc., and thus can better maintain the quality of the crayfish.

[0051] The above are only the preferred embodiments of the present utility model and do not impose any formal limitations on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to equivalent embodiments with equivalent changes within the scope of the technical solution of the present utility model by using the above-disclosed technical content. However, as long as it does not depart from the content of the technical solution of the present utility model, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
