When the automatic food bagging machine works, the automatic food bagging machine is processed through the following steps in sequence:

feeding in a packaging bag: the lifting frame 23 is driven by a cam to lift, and the packaging bag is sucked by the suction cup 22 on the lifting frame 23 and then taken out downwards; then, the swing rod 263 on the first four-bar mechanism 26 swings through a cam, and drives the common V-shaped rod 261 to swing; the first four-bar mechanism 26 drives the second four-bar mechanism 27 to work, so that the swing of the common V-shaped rod 261 is combined with the telescopic motion of the telescopic cylinder 272, the motion track of the fixed clamping plate 281 is driven to be connected with the sucking disc 22 and the feeding position, the clamping cylinder 29 extends at the sucking disc position, the movable clamping plate 282 is driven to press the packaging bag on the fixed clamping plate 281, and the packaging bag is moved backwards to the feeding position, so that the packaging bag is vertical and is clamped by the clamp;

(II) opening the packaging bag: the bag opening cylinder 39 extends to drive the first rack 331 and the second rack 332 to move in opposite directions, so that the inner suction pipe 36 sucks one surface of the packaging bag, the outer suction pipe 37 sucks the other surface of the packaging bag, the packaging bag is pulled open, then the upper blowing pipe 38 blows air from above, and the air is blown into the packaging bag to open the bag;

(III) food filling: the lower end of the conical cylinder 41 is blocked by the opening plate 43, then the lifting rod 48 descends, the rocker 46 drives the central rod 42 to descend, the conical cylinder 41 is close to the packaging bag, and food to be packaged is arranged in the conical cylinder 41; then the cam swing link 44 swings to drive the lateral plate 45 to rotate, so that the opening plate 43 moves laterally, and the food to be packaged falls off from the conical barrel 41 smoothly; the driving rod 54 is lifted by the cam, and the clamping plates 53 are driven to approach each other to clamp the packaging bag filled with food for exhausting in the descending process of the driving rod 54.
