the first air cylinder 13 drives the lower template 12 to move to one end of the linear track, and at the moment, the lower template 12 is positioned right below the lower film pressing plate 14;

the telescopic rod of the second cylinder 18 extends towards the direction of the bottom plate 10, and drives the heat-sealing template 17, the knife rest plate 16, the upper film pressing plate 15 and the lower film pressing plate 14 to descend at the moment;

when the lower die plate 14 contacts the lower die plate 12, the lower die plate 12 is clamped by the lower die plate 14 and does not descend any more, and at the moment, the heat-seal die plate 17, the knife rest plate 16 and the upper die plate 15 continue to descend; when the upper film pressing plate 15 contacts the lower film pressing plate 14, the upper film pressing plate 15 stops descending, at the moment, the coiled film is pressed, and the heat-sealing template 17 and the knife rest plate 16 continue descending; when the knife rest plate 16 is close to the upper film pressing plate 15, the cutter 162 of the knife rest plate 16 enters the first opening hole, the second opening hole and the accommodating groove to cut the rolled film outside the accommodating groove; when the second spring is compressed to a certain distance (namely, the limit column 172 reaches the limit position), the knife rest plate 16 stops descending, at this time, the cutter 162 cuts the coiled film, and the heat-sealing template 17 continues descending; the heat-seal die 173 of the heat-seal die plate 17 enters the first opening, the second opening, the third opening and the containing groove, after the heat-seal die 173 of the heat-seal die plate 17 is pressed and rolled up the film, the cut rolled film is sealed in the bottle mouth of the article at the moment, then the film sealing is completed, then the second cylinder 18 stops working to enable the heat-seal die plate 17, the knife rest plate 16, the upper film pressing plate 15 and the lower film pressing plate 14 to stop, after the film sealing is completed, the telescopic rod of the second cylinder 18 retracts, and at the moment, the heat-seal die plate 17, the knife rest plate 16, the upper film pressing plate 15 and the lower film pressing plate 14 retract in sequence.

Finally, the telescopic rod of the first air cylinder 13 extends to bring the lower template 12 to the other end of the linear track, at the moment, the lower template 12 is positioned right above the third air cylinder 107, and then the telescopic rod of the third air cylinder 107 is controlled to extend to eject the article from the accommodating groove.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
