[0024] like Figures 1 to 3 As shown, through the above arrangement, the automatic sealing and cutting machine in this embodiment respectively completes the process of article conveying, automatic packaging and waste film recycling through the conveying unit, the sealing and cutting unit and the recycling unit; the articles to be packaged are conveyed from the input conveyor belt 200 to the hot cutting zone, and after the articles arrive at the hot cutting zone, they are wrapped by the packaging film, and at the same time, the packaging film is cut by the hot cutting tool to quickly complete the sealing and cutting operation, and after being packaged by the sealing and cutting unit, the packaged articles are output by the output conveyor belt 300, and since the end of the output conveyor belt 300 is provided with a telescopic section, it can be telescoped toward the side of the input conveyor belt 200 when the articles are conveyed, so as to efficiently receive the packages. The finished items can be prevented from falling off in small-sized packages; in this embodiment, the unfolding frame 400 of the sealing and cutting unit is used to unfold the output packaging film, which can ensure that the items are completely wrapped by the packaging film after being transported to the hot-cutting area, and the packaging film is cut by the hot-cutting tool 500 to complete the sealing and cutting operation, and finally the packaged items are output; in the packaging process, the packaging film will be cut by the L-shaped hot-cutting tool 500. The waste generated after the packaging film is cut is recycled and wound on the recycling roller 700 through the rotation of the recycling roller 700, so as to realize automatic recycling, improve packaging efficiency, and reduce manual workload.

[0025] like Figures 1 to 3As shown, in order to ensure smooth transportation of the packaging film and avoid the generation of wrinkles and waste, a tensioning roller 800 for the packaging film to bypass is provided at the output end of the machine body 100 corresponding to the winding module in this embodiment, and the tensioning roller 800 is rotatably mounted on a tensioning frame provided on the machine body 100.
