[0047] The working process of the automatic packaging device for packaging bags of the present invention is as follows: Figure 3 Initially, the first flap 222 and the second flap 223 are both in a horizontal state, the height of the first bracket 21 is higher than the top surface of the first flap 222, the conveyor belt 6 conveys the packaging bag to the top of the first flap 222 and the second flap 223, the first bracket 21 limits the packaging bag to prevent the packaging bag from flying out, when the conveyor belt 6 rotates one circle or half a circle, that is, after conveying a certain number of packaging bags, the conveyor belt 6 stops conveying, and the folding motor 26 starts. Please refer to Figure 4The folding motor 26 drives the first flap 222 to rotate, and the second flap 223 rotates accordingly, and stops moving after hitting the stopper 24. The first flap 222 continues to rotate until it is horizontal. At this time, the torsion spring is squeezed, and the first flaps 222 on both sides fold the two ends of the packaging bag successively. The rotating shaft 221 on one side is higher than the rotating shaft 221 on the other side. The height difference of the rotating shaft 221 is determined by the overall thickness of the packaging bag. Please refer to Figure 5 After the winding is completed, the clamping motor 575 rotates, and the third clamping plate 573 moves down and contacts the packaging bag under the drive of the second cam 576. The clamping motor 55 starts, and drives the sliding frame 56 through the first gear 53, the second gear 54 and the clamping screw 52 to drive the clamping device 57 to extract the rolled packaging bag. After a part of the packaging bag is extracted, the lifting motor 332 drives the guide frame 32 to rise through the lifting screw 331. The cut baling line 4 is placed on the guide frame 32. The baling line 4 can be a metal wire. The baling line 4 is wrapped around the packaging bag under the guidance of the guide frame 32. The telescopic cylinder 341 is started to drive the first clamping plate 345 to move down close to the baling line 4. The strapping driver 35 is started to make the two first clamping plates 345 approach and clamp the two ends of the baling line 4. The strapping motor 343 is started to drive the first clamping plate 345 to rotate, so that the two ends of the baling line 4 are entangled together, and the baling line 4 and the packaging bag are tied in place. Please refer to Figure 7 After bundling is completed, the third clamping plate 573 is separated from the packaging bag, releasing the restriction on the packaging bag, and the sliding frame 56 moves away from the packaging bag. At the same time, the guide frame 32 moves down away from the packaging bag, and the bundled packaging bag automatically falls down along the guide slope 7 and slides into the recycling box 8. After completing the bundling of this part of the packaging bags, the bundling of the next part of the packaging bags continues, and the work is cyclical.
