[0031] The packaging production line structure and the conveying structure of the upstream equipment are used in cooperation, the soft cushion product is conveyed to the rolling structure 1 through the conveying structure of the upstream. In the initial use, the rolling film 35 is installed first, then the rolling film is pulled out and pulled between the fixed pressing beam 38 and the driving pressing beam 37, and the rolling film is pressed and fixed through the film pressing cylinder 36, and then the rolling and boxing operation is started.

[0032] Firstly, the film pulling telescopic rod 31 drives the electric film clamp 33 to descend and clamp the rolling film, the film pressing cylinder 36 drives the rolling film to be released, and then the film pulling telescopic rod 31 drives the rolling film to be pulled up, so that the rolling film is intercepted in front of the soft cushion product. When the soft cushion product moves from the upstream to the rolling structure 1, the soft cushion product first contacts the rolling film, and then pushes the rolling film during the continuous forward movement. Since one side of the rolling film is clamped and fixed, the pushing of the soft cushion product will make the rolling film form a U shape and cover the upper surface and the lower surface of the soft cushion product. When the soft cushion product covered with the rolling film moves below the upper pressing structure 14, the second lifting motor 26 drives the closed-loop conveying belt 19 and the conveying roller to descend and cooperate with the closed-loop conveying belt 19 and the conveying roller of the lower pressing structure 16 to press and clamp the soft cushion product. The cooperation of the upper pressing structure 14 and the lower pressing structure 16 provides power to drive the soft cushion product to continue to move forward. At this time, the discharge electric telescopic rod 23 drives the lower rolling frame 20 to swing upward, so that the lower rolling structure 17 cooperates with the upper rolling structure 15 to form a rolling cavity. The soft cushion product enters the rolling cavity under the conveying of the upper pressing structure 14 and the lower pressing structure 16 and contacts the toothed roller 22. Under the driving of the toothed roller 22, the soft cushion product bends upward and contacts the upper rolling structure 15. Under the driving of the upper rolling structure 15, the soft cushion product starts to bend and wind until the rolling is completed. During the rolling process, the mounting frame 11 drives the upper rolling structure 15 to gradually move backward and upward to adapt to the gradually increasing soft cushion roll. After the rolling is completed, the film pressing cylinder 36 drives the rolling film to be clamped and fixed again. The film cutting telescopic rod 39 drives the heating roller 41 to approach the rolling film and heat seal and cut off the rolling film. Finally, the film cutting telescopic rod 39 and the discharge electric telescopic rod 23 are reset in sequence. The lower rolling structure 17 swings downward, and the completed soft cushion roll automatically rolls down to the boxing table of the box pushing assembly 2.

[0033] When the box pushing assembly 2 is used, the position of the guide frame 49 is adjusted according to the size of the soft cushion roll, so that the guide frame 49 and the soft cushion roll are located on the same axis, and then the soft cushion roll falls on the boxing table. At the same time, the mechanical arm 3 sucks up the carton through the cooperation of the first box grabbing plate 42 and the second box grabbing plate 43 and moves to insert one end of the guide frame 49 into the carton. The pushing motor 47 is started and drives the pushing plate 48 to move, and at the same time, the goods are pushed to the guide frame 49 and enter the carton under the guidance of the guide frame 49. Then the carton is moved to the carton sealing structure for sealing, and the carton packaging process is completed.

[0034] The above-described embodiment only expresses one implementation manner of the utility model, and the description is relatively specific and detailed, but cannot be understood as a limitation on the utility model patent scope. It should be noted that, for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
