Transporting the product to be packaged to a paperboard 8 positioning machine 3 through a feeding machine 1 and a conveyor 2; the flat paper boards 8 are transported to the paper board 8 positioning machine 3 through the paper board 8 lifter 5; grabbing the paper board 8 onto the paper board 8 positioning machine 3 through the grabbing machine 4, grabbing and placing a product to be packaged onto the paper board 8 positioned on the paper board 8 positioning machine 3, wherein the product to be packaged is placed on the paper board portion 81 of the paper board 8; the cardboard 8 with the product to be packaged is moved towards the carton folder 6 by means of the cardboard 8 positioning machine 3.

On the carton folding machine 6, the first pushing component 66 is firstly utilized to limit the second carton parts 82 at the front end and the rear end of the carton 8, then the first contact piece 664 of the first pushing component 66 is utilized to fold the second carton parts 82 upwards and inwards, and meanwhile, the second carton parts 82 drive the second folding lugs 821 to lift; after the second portion 82 of the blank is folded over; the second first contact member 667 moves to turn over the second folding lug 821 inwards; while maintaining the state of the first pushing member 66, the second pushing member 63 is actuated to push the third portion 83 of the paper sheet upward and inward by the second contact member 635, and the third portion 83 of the paper sheet is used to hold the second tab 821; while the three paper boards 83 are folded, the four paper boards 84 are lifted, and the third pushing assembly 64 is used for pushing the four paper boards 84 to be folded inwards; while the four portions 84 of the paper board are folded, the first pushing assembly 66 and the second pushing assembly 63 are slightly loosened, so that a space is generated between the two portions 82 of the paper board and the product to be packaged, the four folding lugs 841 are folded downwards and inwards by the fourth pushing assembly 65 and are inserted between the two portions 82 of the paper board and the product to be packaged, and the first pushing assembly 66, the second pushing assembly 63, the third pushing assembly 64 and the fourth pushing assembly 65 apply force to tighten the carton, so that the folding of the paper board 8 into the carton under the condition of placing the product is completed.

Then, the first pushing unit 66, the second pushing unit 63, and the fourth pushing unit 65 are reset, and the carton folding machine 6 conveys the folded carton to the capper while the third pushing unit 64 presses the four cardboard portions 84, and the capper bonds the three cardboard portions 83 of the folded carton with an adhesive tape while the carton is moving.

And finally, the carton is conveyed by the sealing machine to move towards the bag turning machine 7, and the carton is clamped by the bag turning machine 7 and leaves the packaging production line.
