[0031] The operation process of this embodiment is as follows: During the production process, stacks of neatly stacked packaging boxes are produced and conveyed from right to left by the conveyor 5, so that the whole stack of packaging boxes is conveyed to the left end of the conveyor 5. The strapping paper on the strapping tape roller 304 is unfolded, and the strapping paper passes through the guide roller 306 and the rectangular frame 308 in sequence, so that the end of the strapping paper is located between the electromagnetic iron plate 215 and the pulling plate 207. Then, the electromagnetic iron plate 215 is powered on, so that the electromagnetic iron plate 215 generates suction force, and then drives the electromagnetic iron plate 215 to move towards the pulling plate 207, so that the electromagnetic iron plate 215 presses the strapping paper, thereby completing the fixation of the end of the strapping paper. Then, control the whole stack of packaging boxes to move into the L-shaped positioning plate 102 on the base 101, so that the whole stack of packaging boxes is closely attached to the inside of the L-shaped positioning plate 102. Then, the electromagnetic iron plate 215 is powered off, and under the elastic force of the spring 217, the electromagnetic iron plate 215 is driven to move away from the pulling plate 207, so that the electromagnetic iron plate 215 is separated from the strapping paper. Then, the first electric telescopic rod 212 is started, and the first electric telescopic rod 212 drives the push-pull plate 213 to move to the left, so that the push-pull plate 213 drives the first L-shaped fixing plate 206 and the second L-shaped fixing plate 209 to move towards each other through the rotating rod 210, and then drives the pressing plate 204 and the pulling plate 207 to move towards each other.

When the pressing plate 204 abuts against the base 101, the strapping of the whole stack of packaging boxes is completed. Subsequently, the second electric telescopic rod 103 is started, so that the second electric telescopic rod 103 drives the L-shaped discharging plate 104 to move backward, thereby driving the whole stack of strapped packaging boxes to move backward, completing the alignment and discharging operation. At the same time, the cutting knife 205 on the pressing plate 204 moves into the cutting groove 106, thereby completing the cutting of the strapping paper.

[0032] Meanwhile, the pulling plate 207 moves upward. At this time, the electromagnetic iron plate 215 is electrified again, driving the electromagnetic iron plate 215 to move in the direction close to the pulling plate 207, so as to complete the clamping of the electromagnetic iron plate 215 on the bundling paper at the cutting place. Subsequently, the first electric telescopic rod 212 is controlled to drive the push-pull plate 213 to move to the right to reset, and then the first L-shaped fixing plate 206 and the second L-shaped fixing plate 209 are driven to move away from each other through the rotating rod 210, and further drive the pressing plate 204 and the pulling plate 207 to move away from each other.
