[0066] Working principle:

[0067] The first motor 2 is started to drive the first sprocket 3 to rotate and then drive the first belt (not shown) to run. After the first belt (not shown) runs, it drives the first moving plate 6 to move and then drives the feed plate 7 to move. The movement of the feed plate 7 drives the food above the feed plate 7 to move until the feed plate 7 moves to the lifting plate 9. Then the lifting member is started to drive the lifting plate 9 to move up to the packaging station, so as to achieve the purpose of feeding. The support plate 8 and the lifting plate 9 are arranged at intervals so that the support plate 8 can move to a state where it is in a cross state with the lifting plate 9. Before the food is sent to the packaging station, the cling film will be pre-moved to the top of the food under the action of the mobile clamping member, and then the food will be pushed up under the action of the lifting plate, so that the cling film wraps the food, and then the cling film is cut by the horizontal cutting plate and the longitudinal cutting plate, and then it returns to its original position for the next video packaging.

[0068] The start-up driving member drives the lifting block 40 to move and then drives the movable plate 39 to move up and down. The movement of the movable plate 39 drives the pressing plate 38 to move until the pressing plate 38 can press the cling film above the pressing plate 38 .

[0069] The roller of the cling film is put on the fixed shaft 60, and one end of the cling film is pulled to be placed on the fixed clamping piece 59. Then, the mobile driving piece is started to drive the mobile clamping piece 58 to the fixed clamping piece 59 to clamp one end of the cling film. Then, the mobile clamping piece 58 clamps one end of the cling film. Under the action of the mobile driving piece, the cling film is pulled to the middle of the workbench 56. After completing the packaging of the cling film, the mobile clamping piece 58 moves back to the fixed clamping piece 59 to continue clamping the cling film, thereby realizing repeated and efficient film feeding. When powered on, the electromagnetic block 62 is magnetic and moves toward the direction of the positioning magnetic block 63, thereby clamping the cling film between the electromagnetic block 62 and the positioning magnetic block 63. It is worth noting that the cling film is squeezed and fixed when it is at the fixed clamping piece 59. Under the pull of the mobile clamping piece 58, the cling film can be moved.
