After the envelope paper bag is broken, it enters the paper bag conveying assembly 200. The rotation speed of the paper bag conveying assembly is faster than the breaking speed. Each envelope paper bag is pulled apart and sent to the upper pressing roller assembly 300 and the lower roller assembly 400. A notch is opened on the outer circumferential surface of the upper pressing wheel 302 (see Figure 3). When the paper bag enters the upper and lower pressing rollers, the upper pressing wheel does not contact the paper bag. When the paper bag reaches the positioning plate 509, the front edge of the paper bag stops moving, and the pressure strip 510 presses the front edge of the paper bag to prevent the paper bag from bulging. When the cam 408 rotates to the high point of the roller, the positioning plate 509 extends out of the upper plane of the support plate 508 to block the paper bag. When the cam is at the low point,

Under the action, the rotating shaft 501 swings and drives the positioning plate 509 to extend under the supporting plate. When the positioning plate 509 extends under the supporting plate, the outer circle notch of the upper pressing wheel 302 rotates, and the outer circle of the upper pressing wheel contacts the outer circle of the lower roller to press the paper bag and move it smoothly on the paper bag machine.
