A clamping plate 74 is also fixed to one side of the plug-in plate connecting plate 72 by a fastener. The plug-in plate connecting plate 72 and the clamping plate 74 clamp the belt 52. By adjusting the position of the plug-in plate connecting plate 72 and the clamping plate 74 on the belt 52, the distance between the two groups of inner plug-in plates 9 and outer plug-in plates 8 at the plug-in position can be adjusted, further adapting to the bag opening size of different packaging bags, so that the device can To organize the packaging bags of different types, the outer insert plate 8 and the inner insert plate 9 are respectively located on both sides of the straight slot, the two inner insert plates 9 are respectively arranged on the inner sides of the two ends of the packaging bag opening, and the two outer insert plates 8 are respectively arranged on the outer sides of the two ends of the packaging bag opening. The belt 52 rotates, and the two sides of the belt 52 will move relative to each other. The outer insert plate 8 is inserted into the inner insert plate 9 to form the bag opening into an M shape. The installation position of the outer insert plate 8 and the inner insert plate 9 can be controlled by the position of the clamping plate 74 and the insert plate connecting plate 72. When the clamping plate 74 and the insert plate connecting plate 72 clamp the belt 52, the inner insert plate 9 and the outer insert plate 8 moves along with the belt 52, and the positions of the inner insert plate 9 and the outer insert plate 8 are fixed. When changing to a different type of packaging bag, the positions of the inner insert plate 9 and the outer insert plate 8 on the belt 52 can be adjusted by loosening the fasteners, so that the distance between the two different plug-in positions can be adjusted, so that the distance can meet the bag opening requirements of different packaging bags, thereby enabling the device to sort out the bag openings of different types of packaging bags.
