Under the drive of the circulating driving cylinder 532, the two hot pressing sealing plates 533 can move towards and away from each other in a cycle; the cutting knife 535 is arranged inside any one of the hot pressing sealing plates 533, and the cutting driving cylinder 536 is arranged at one end of the cutting knife 535 away from the other hot pressing sealing plate 533. The cutting driving cylinder 536 can drive the cutting knife 535 to move inside the corresponding hot pressing sealing plate 533.
[0049] When the two hot-pressing sealing plates 533 are fitted together, the cylindrical packaging materials on the outside of two adjacent materials can be sealed, and the cutting drive cylinder 536 drives the cutting knife 535 to move to cut off the cylindrical packaging materials on the outside of two adjacent materials; the independent discharge mechanism 6 includes a rotating bracket 61 and a rotating wheel 62, the rotating bracket 61 is arranged at the rear end of the hot-sealing mechanism 53, the rotating wheel 62 is rotatably arranged inside the rotating bracket 61, the rotating wheel 62 can rotate freely under the limit of the rotating bracket 61, and a plurality of rotating plates 621 are arranged on the outside of the rotating wheel 62; when each packaged material falls on the rotating plate 621, the entire rotating wheel 62 can be driven to rotate, and the next packaged material falls on the next rotating plate 621, and is discharged one by one through the rotation and guidance of the rotating plate 621.
[0050] Therefore, by setting the two sealing conveying belts 52 of the sealing and cutting mechanism 5, while the cylindrical packaging material outside the material inside the two sealing conveying belts 52 and the material continue to be conveyed at the speed of the front end, the expansion degree of the cylindrical packaging material outside the material can be adjusted by adjusting the two sealing conveying belts 52, so as to control the inflation amount inside the formed packaging bag, effectively ensuring that the inflation amount inside the formed packaging bag meets the specified requirements, and when the cylindrical packaging material outside the material and the material continue to move, the two hot pressing sealing plates 533 are driven by the circulating driving cylinder 532 to approach and close to each other. Away from the movement of the cycle, when the two hot-pressing sealing plates 533 are fitted together, the outer cylindrical packaging materials of two adjacent materials are sealed, and the cutting drive cylinder 536 drives the cutting knife 535 to move, and the outer cylindrical packaging materials of two adjacent materials are cut off to complete the packaging and sealing of the previous material; then when each packaged material falls onto the rotating plate 621, the entire rotating wheel 62 can be driven to rotate, and the next packaged material falls onto the next rotating plate 621, and is discharged one by one through the rotation and guidance of the rotating plate 621, which can effectively prevent stacking and ensure the effectiveness of counting.
