[0002] Food packaging is an integral part of food products. It protects food from damage by biological, chemical, and physical external factors during the circulation process from the factory to the hands of consumers. It can also maintain the stable quality of the food itself, facilitate the consumption of food, and is the first to show the appearance of the food and attract consumers. It has value beyond the material cost.

[0003] Instant Liuzhou river snail rice noodles usually have a staple food package, a side dish package, and a sauce package outside the packaging bag. There are outward creases on both sides of the bag body of the packaging bag. During the bagging operation, the following steps are required: 1. Open the bag mouth of the packaging bag; 2. Load the staple food package outside the packaging bag and then push the staple food package to the bottom of the packaging bag; 3. Load the side dish package and the sauce package in sequence; 4. Level the bag mouth of the packaging bag and then seal it. Currently, the bagging is carried out manually, and then sealed by a sealing machine. The efficiency of bagging and sealing is low, so it is necessary to make improvements.

[0110] In this embodiment of the present application, due to the adoption of the above structure, several staple food bags are placed in the staple food bag storage slot 63 and are individually placed on the input conveyor belt 62 by manual feeding. The staple food bags are moved by the input conveyor belt 62 to a position corresponding to the conveying slot 67, that is, below the pushing slide rail 64. The conveying conveyor belt 1 pauses operation. The lateral movement driving member 66 (which can be one of a cylinder, a hydraulic cylinder or an electric push rod) causes the pushing slider 65 to push the staple food bag at one end on the conveyor belt 1 to the outer end of the conveying slot 67. After the rotatable suction cup 69 sucks the staple food bag, it rotates clockwise to move the staple food bag between the pair of bag-supporting frames 612. The pair of bag-supporting frames 612 are driven by corresponding lateral movement cylinders to close, so that the position of the staple food bag is aligned with the bag mouth of the packaging bag on the lower fixture 4. Subsequently, the suction cup releases the fixation of the staple food bag and flips counterclockwise to reset. At the same time, the filling block 610 is driven by the filling cylinder 611 to fill the staple food bag between the pair of bag-supporting frames 612 into the lower packaging bag.

[0128] In this embodiment of the present application, due to the adoption of the above structure, the bag mouth moves between a pair of fixed frames 42 under the action of the packaging bag conveying device 5, and the outer and inner sides of the folded edges 5132 on both sides of the bag mouth respectively move between a corresponding pair of clamping plates 463 and the ends of the corresponding clamping rods 465 and between a pair of clamping grooves 453 and the outer ends of the corresponding inner sliding rods 456. At this time, each clamping block 452 and each end block 462 are separated from each other, and an external air source supplies air into the inner cavities of each inner sliding sleeve 451 and each outer sliding sleeve 461, so that the outer ends of each outer sliding rod 467 and each inner sliding rod 456 extend out. When the outer ends of each outer sliding rod 467 extend out, the corresponding clamping rod 465 is pushed to rotate around its hinge point with the end block 462 through the corresponding connecting rod 466, and the outer side of the folded edge 5132 of the packaging bag is clamped between the bent end of the clamping rod 465 and the corresponding clamping block 452.

At this time, the bag mouth remains open, and each folded edge 5132 is in an open state;

[0129] When the packaging bag filled with the staple food bag, side dish bag and sauce bag moves away from the sauce packaging bag device 8 under the movement of the rotatable machine table 2 and moves to the lower part of the alignment box 112, the rotatable machine table 2 pauses. Each alignment rotating shaft 113 rotates relatively under the cooperation of the alignment driving motor and the gear, so that a pair of fixed blocks 114, a pair of alignment rods 115 and a pair of alignment thin plates 116 approach each other. A pair of alignment plates extend into the hems 5132 on both sides of the packaging bag opening. Subsequently, the clamping driving motor acts, and cooperates with the gear to drive a pair of swing arms 41 to swing simultaneously, so that the outer ends of the pair of swing arms 41 move away from each other, increasing the length and decreasing the width of the packaging bag opening. At the same time, the pushing cylinders 47 cooperating with the respective clamping blocks 452 and end blocks 462 act, so that the clamping blocks 452 and the corresponding end blocks 462 on the same side approach each other until the adjacent outer walls are in contact, reducing the width of the packaging bag opening. Subsequently, the alignment rotating shaft 113 rotates under the cooperation of the alignment driving motor and the gear, so that a pair of fixed blocks 114, a pair of alignment rods 115 and a pair of alignment plates move away from each other, and each alignment plate disengages from the corresponding hem 5132. At this time, the packaging bag opening closes, and each hem 5132 is also aligned, which helps to keep the packaging bag opening flat during the next heat sealing.
