A second cylinder 19 is fixedly installed in the middle of the top of the body 1, and a hot pressing head 20 is fixedly connected to the bottom of the second cylinder 19;

[0022] During use, the packaging structure to be sealed is placed on the upper surface of the middle section of the body 1, and then the set lower pressing plate 18 is used to fully press and limit the packaging structure to ensure its stability during the subsequent sealing process. Then, the second cylinder 19 works to longitudinally push the hot pressing head 20 fixedly connected to its bottom, and the set hot pressing head 20 is used to seal the packaging structure;

[0023] As a further implementation manner of this embodiment, as Figure 1 , Figure 2 and Figure 3 shown, an air intake groove 2 is opened on one side of the bottom of the body 1. The air intake grooves 2 are equidistantly distributed on the side wall of the body 1, and the air intake groove 2 and the body 1 form an integrated structure. A ventilation cavity 3 is opened in the inner cavity of the body 1, and an air outlet hole 4 is opened in the middle of the top of the body 1. A filter cotton stacking plate 5 is arranged inside the ventilation cavity 3, and an adsorption carbon plate 6 is distributed on one side of the filter cotton stacking plate 5. The other side of the adsorption carbon plate 6 is distributed with a partition plate 7, and a flow guide seat 8 is fixedly installed on the side wall of the partition plate 7. A flow guide groove 9 is opened on the inner side of the bottom of the flow guide seat 8, and a cold air blower 10 is installed on the inner side of the top of the flow guide seat 8. A fixed side plate 11 is fixedly installed on the inner side of the middle section of the body 1, and a first cylinder 12 is fixedly installed on the side wall of the fixed side plate 11. One end of the first cylinder 12 is fixedly connected with an adjustment seat 13. A guide rod 14 is distributed on one side of the first cylinder 12. The fixed side plate 11, the first cylinder 12, the adjustment seat 13 and the guide rod 14 form an adjustment structure, and the adjustment structure is arranged on the inner side of the middle section of the body 1. A pressing rod 15 passes through one end of the adjustment seat 13, and one end of the pressing rod 15 is fixedly connected with a movable plate 16. A return spring 17 is sleeved on the outer surface of the pressing rod 15. The bottom of the pressing rod 15 is fixedly connected with a lower pressing plate 18.

[0025] Specific working principle:

[0026] During use, first place the packaging structure to be sealed at the inner surface of the middle section of the machine body 1. First, the first cylinder 12 works to horizontally push the adjustment seat 13, and then the adjustment seat 13 drives the guide rod 14 to move horizontally along the fixed side plate 11, so as to improve the stability of the adjustment seat 13 during the horizontal movement.
