[0022] ​On the basis of the above embodiment, the packing support 1 is filled with a sealing strip 11; both sides of the sealing strip 11 are provided with photoelectric sensors 12; the area enclosed by the sealing strip 11 is provided with a communicating air flow hole 13; one side of the air flow hole 13 is provided with a deformation assembly 14, which is deformed and lifted up along the height direction under the action of an electric field. The sealing strip on the packing support improves the sealing property of the negative pressure cavity, ensuring the vacuum packaging effect. The photoelectric sensor can detect the placement of eels, realizing automatic control process. The air flow hole cooperates with the negative pressure mechanism to draw air, enhancing the vacuum effect. The deformation assembly under the action of the electric field can lift up the eels, making their position more appropriate during packaging, avoiding the influence of improper position of eels on the appearance of the package during packaging, and improving the regularity of the package.

[0023] On the basis of the above embodiment, the deformation assembly 14 comprises a first deformation layer, an insulating layer and a second deformation layer which are sequentially adhered; the first deformation layer, the insulating layer and the second deformation layer are all inserted in the mounting sleeve; the first deformation layer and the second deformation layer are both strip-shaped piezoelectric ceramics which are deformed along the vertical direction. The deformation assembly adopts the structure composed of the first deformation layer, the insulating layer and the second deformation layer, and the first and second deformation layers are strip-shaped piezoelectric ceramics, which makes the deformation assembly accurately deformed along the vertical direction under the action of the electric field. The characteristics of piezoelectric ceramics ensure the stability and repeatability of deformation, which can reliably lift up the eels, providing stable support for the position adjustment of eels during packaging, and improving the stability of packaging quality.

[0024] On the basis of the above embodiment, the negative pressure cover 4 comprises a hollow cover 41; the bottom of the cover 41 extends outward to form a sealing surface; the top of the cover 41 is sealingly inserted with a socket 42, and the socket 42 and the cover 41 are connected by a spring; one side of the socket 42 is detachably installed with a heat sealing head 43; the height of the heat sealing head 43 is much smaller than the height of the cover 41. The hollow cover structure of the negative pressure cover is conducive to forming a negative pressure space.

[0027] The specific working process of the utility model is as follows: the eel to be packaged is placed in the area enclosed by the sealing rubber strip on the packaging support. At this time, the photoelectric sensor detects the placement of the eel and triggers the subsequent action. The driving cylinder is started, and the negative pressure cover is pushed to the negative pressure mechanism. In the process of approaching, the heat sealing assembly on the negative pressure cover descends with the negative pressure cover. When the negative pressure cover is tightly attached to the packaging support, a sealed negative pressure cavity is formed.

At the same time of vacuumizing, the electric field is applied to the deformation assembly, and the first deformation layer and the second deformation layer are deformed along the vertical direction under the action of the electric field, and the eel is lifted to make its position more appropriate, which is convenient for packaging. At the same time, the whole packaging bag can be evenly in the negative pressure, and the packaging will not be affected by the existence of gas in the local part. When the set vacuum degree is reached, the heat sealing assembly further descends and heat seals the packaging material under the continuous action of the driving cylinder. After heat sealing, the driving cylinder drives the negative pressure cover to rise and leave the packaging support, completing a packaging process.
