The lower heat-sealing cutter is arranged on a base, and the base is provided with a first lifting power source. The upper backing plate is arranged at the left end of a first support arm, and the first support arm is provided with a second lifting power source. Its characteristics are that: air guiding plates are arranged on both the front and rear sides of the upper backing plate. The lower end surface of the air guiding plate is slightly higher than the lower end surface of the upper backing plate, and an air discharge hole is arranged on the lower end surface of the air guiding plate. An air inlet hole connecting each air discharge hole is arranged on the right side surface of the air guiding plate, and the air inlet hole is connected with a positive pressure air source.

[0005] The upper backing plate and the two air guiding plates are matched and installed in the notch at the lower end of a connecting seat, and the connecting seat is installed on the first support arm.

[0006] The lower heat-sealing cutter includes a heat-sealing head and a cutter head located in the middle of the heat-sealing head. Correspondingly, the upper backing plate includes a heat-sealing area and a cutter groove located in the middle of the heat-sealing area.

[0007] A guide rod is also arranged on the first support arm. The guide rod is installed on the first support arm through an end seat and is arranged in front of the upper backing plate.

[0008] A first lifting sliding pair is arranged at the right end of the first support arm and is driven by a second lifting power source.

[0009] A second support arm arranged side by side and lifting synchronously is arranged behind the first support arm. A pressing plate is arranged at the left end of the second support arm. A second lifting sliding pair is arranged at the right end of the second support arm and is driven by a second lifting power source.

[0010] The beneficial effect of the utility model is that the improved air-cooled strapping machine heat-sealing and cutting mechanism adopts air cooling in combination with heat-sealing and cutting. Specifically, air guide plates are arranged on the front and rear sides of the upper pad plate, and air blowing holes and air inlet holes are arranged on the air guide plates. By connecting to a positive pressure air source, air is blown to the heat-sealing and cutting position to achieve rapid cooling, reduce waiting time, and improve strapping efficiency.
