When the plastic packing bag passes between the two sealing wheels 110, the two sealing wheels 110 seal the plastic packing bag after heating, and the sealed plastic packing bag passes between the two embossing wheels 120 along with the continuous running of the conveyor belt 300, and the two embossing wheels 120 press stripes or reticulate patterns at the sealing position of the plastic packing bag. Since the interval between the two embossing rollers 120 is smaller than the interval between the two sealing rollers 110, the two embossing rollers 120 roll the plastic packing bag sealed by the sealing rollers 110 again, thereby ensuring the sealing of the plastic packing bag to be tight.
The device seals the plastic packaging bag in a rolling way by using the heated sealing wheel 110, and the device can seal the plastic packaging bag no matter whether the bag mouth of the plastic packaging bag is long or short.
