[0002] Packaging machines are a type of equipment frequently used in modern industrial production. They can package finished products to facilitate their subsequent storage and transportation. Sealing is an important step in packaging machines. However, different products require different sealing methods. Some products require heat shrink sealing with a horizontal sealing knife, while others require composite sealing. However, existing reciprocating packaging machines can only perform one sealing mode. In the face of different sealing requirements, different packaging machines need to be used for sealing, which is very troublesome.

[0003] At present, most of the existing reciprocating packaging machines have the problem of single cutting and low utilization rate, and cannot achieve dual-use of one end or multiple uses of one machine. Summary of the Invention

[0010] The beneficial effect of adopting the above further solution is that by providing a sliding connection mechanism, the cutting mechanism can be better connected to the belt input mechanism, thereby preventing the cutting mechanism from loosening during operation.

[0015] The beneficial effect of adopting the above further scheme is: the retractable upper tool and the compound upper tool are arranged relative to each other, and the switching between the retractable upper tool and the compound upper tool can be completed by adjusting the rotating tool base, achieving a dual-purpose effect, improving utilization and reducing costs.

[0016] Furthermore, a sliding guide rail is provided on the side wall of the horizontal sealing fixed main frame, and the sliding block and the vertical sliding block are both connected to the sliding guide rail.
