When the first driving member drives the first heat-sealing device in the reverse X direction, the first pusher can separate the lightweight packaging bag from the first heat-sealing plate on the first heat-sealing device. When the second driving member drives the second heat-sealing device in the X direction, the second pusher can separate the lightweight packaging bag from the second heat-sealing plate on the second heat-sealing device. Compared with the existing technology, this can solve the problem of lightweight packaging bags sticking to the heat-sealing edge after cutting;

[0003] When the current packaging bag sealing machine cutting mechanism is in use, by providing a first pushing part and a second pushing part, the first driving member and the first heat sealing device move in the X direction. The first pushing part can separate the lightweight packaging bag from the first heat sealing plate on the first heat sealing device. The second driving member drives the second heat device to move in the X direction. The second pushing part can separate the lightweight packaging bag from the second heat sealing plate on the second heat sealing device.

The packaging bag is then cut using a cutting mechanism. Since the height of the cutting mechanism cannot be adjusted, it cannot cut packaging bags of different heights, thereby reducing the scope of application of the packaging bag sealing and cutting mechanism.

[0021] During the use of the traditional packaging bag sealing machine cutting mechanism, the packaging bag is placed on the inner side of the two heat sealing plates. The heat sealing plates move inward to fit the packaging bag. At the same time, the heat sealing plates heat and melt the packaging bag to complete the sealing of the packaging bag. The packaging bag is then cut using the cutting mechanism.
