At this time, the second roller 13 has a gathering structure, which can make the two sides of the packaging bag gradually curl up when the packaging bag slides. At this time, the pressure rod 14 will press down on the middle of the packaging bag and cooperate with the second roller 13 to make the packaging bag curl up, so that the packaging bag can be folded. This step, by setting the pressure rod 14 and the second roller 13, can make the two sides of the packaging bag gather towards the middle during the packaging bag conveying process. At this time, the packaging bag can be automatically folded, which can reduce the manual folding of the packaging bag, which can lead to unevenness and affect the finished product effect. This improves the folding effect of the packaging bag and also improves the folding efficiency of the packaging.

[0028] like Figure 2 As shown, a groove 2 is provided in the middle of the pressure rod 14; a spring telescopic rod 21 is fixedly connected to the side wall of the groove 2; a roller 22 is fixedly connected to the end of the spring telescopic rod 21; the roller 22 is located near the side wall of the fixed rod 12; during operation, when the pressure rod 14 presses down on the packaging bag during folding, the roller 22 will contact the packaging bag and rotate with the packaging bag, which can reduce the friction between the pressure rod 14 and the packaging bag. This step, by setting the spring telescopic rod 21 and the roller 22, can contact the packaging bag and rotate with it when folding the packaging bag, which can reduce the friction of the pressure rod 14 when pressing down on the packaging bag and improve the stability of folding the packaging bag.

[0029] like Figure 4 As shown, a vacuum pump 3 is fixedly connected to the bottom of the fixed plate 1; a gas guide pipe 31 is connected to the top of the vacuum pump 3; multiple gas guide covers 32 are connected to the side wall of the gas guide pipe 31; when working, starting the vacuum pump 3 can drive the airflow from the gas guide cover 32 into the gas guide pipe 31 and then out of the vacuum pump 3. At this time, the gas guide cover 32 is located between two close first rollers 11, which allows the airflow to flow between the first rollers 11. When the packaging bag is conveyed on the surface of the first roller 11, the packaging bag can fit more tightly with the first roller 11. This step, by setting the vacuum pump 3 to connect the gas guide pipe 31 and the gas guide cover 32, allows the airflow to flow between the two close first rollers 11, and the packaging bag fits more tightly with the first roller 11 when it is conveyed, so as to improve the stability of the position of the packaging bag during conveying.

[0030] like Figure 1 As shown, the first roller 11 has multiple connecting grooves 4 in the middle; belts 41 are connected in the connecting grooves 4; the belts 41 are staggered; during operation, when the first roller 11 rotates, it can drive the connecting grooves 4 to rotate simultaneously. At this time, the belts 41 are connected between two close first rollers 11, which can increase the contact surface between the packaging bag and the first roller 11, making the packaging bag more stable during transportation. This step, by setting the belts 41 to connect two close first rollers 11, can increase the contact surface between the packaging bag and the first roller 11, reduce the situation of the packaging bag falling between the first rollers 11, improve the stability of the packaging bag when being transported on the surface of the first roller 11, and at the same time increase the friction between the packaging bag and the first roller 11 to reduce slippage.

[0031] like Figures 4 to 5 As shown, multiple third rollers 5 are rotatably connected to the side wall of the fixed plate 1; multiple bristles 51 are fixed to the side wall of the third rollers 5; during operation, when the first roller 11 rotates, the bristles 51 contact the surface of the first roller 11 from below, and the third rollers 5 can rotate simultaneously with the first roller 11. At this time, the bristles 51 can clean the surface of the first roller 11, removing the dust and particulate impurities adhering to the surface of the first roller 11. This step, by setting the third rollers 5 and the bristles 51 to rotate simultaneously with the first roller 11, can clean the surface of the first roller 11, thereby reducing the dust adhering to the surface of the first roller 11 from sticking to the surface of the packaging bag and causing dirt, and at the same time reducing the possibility of particulate impurities scratching the packaging bag.

[0032] like Figure 5 As shown, a collection groove 6 is fixedly connected to the side wall of the fixed plate 1; a drawer box 61 is placed in the collection groove 6; the collection groove 6 and the drawer box 61 are in sliding fit; during operation, some dust and particulate impurities swept off the surface of the first rotating roller 11 will fall into the drawer box 61 below and be collected. After collection is completed, the drawer box 61 is taken out from the collection groove 6, the dust and impurities are poured out, and then the drawer box 61 is put back into the collection groove 6. This step can collect the swept dust and impurities by setting the collection groove 6 and the drawer box 61. The removable and repositionable setting of the drawer box 61 can improve the convenience of collecting the swept dust and impurities.

[0033] like Figure 3As shown, the top of the air guide hood 32 is provided with a filter plate 7; the filter plate 7 is detachable; during operation, when the airflow enters the air guide hood 32, it will pass through the filter plate 7. At this time, the filter plate 7 will filter the airflow, removing dust and impurities from the airflow. After filtration, the filter plate 7 can be removed, cleaned, and then reinstalled. This step, by setting the filter plate 7, can filter the airflow entering the air guide hood 32, thereby reducing the accumulation and blockage of dust and impurities in the airflow, which may affect the normal flow of airflow.

[0034] like Figure 1 As shown, a rubber pad 8 is fixed to the side wall of the second roller 13. During operation, when the packaging bag is conveyed to the surface of the second roller 13, the packaging bag will come into contact with the rubber pad 8. This step, by setting the rubber pad 8 to connect the second roller 13, can increase the friction between the packaging bag and the second roller 13 when the packaging bag is conveyed to the surface of the second roller 13, and reduce the situation of the packaging bag sliding when it gathers together.

[0035] Working principle: When the express plastic packaging bag is folded, it is conveyed from the surface of the first roller 11 to the second roller 13. At this time, the second roller 13 has a converging structure, which can make the two sides of the packaging bag gradually curl up when the packaging bag slides. At this time, the pressure rod 14 presses down on the middle of the packaging bag, which works with the second roller 13 to make the packaging bag curl up and fold the packaging bag. When the packaging bag is folded, when the pressure rod 14 presses down on the packaging bag, the roller 22 will contact the packaging bag and rotate with the packaging bag, which can reduce the friction between the pressure rod 14 and the packaging bag. The vacuum pump 3 is started, which can drive the airflow from the air guide hood 32 into the air guide pipe 31 and then out of the vacuum pump 3. At this time, the air guide hood 32 is located between two close first rollers 11, which can allow the airflow to flow between the first rollers 11. When the packaging bag is conveyed on the surface of the first roller 11, it can make the packaging bag fit more tightly with the first roller 11. When the first roller 11 rotates, it can drive the connecting groove 4 to rotate at the same time. At this time, the belt 41 connects the two close first rollers 11. Between the first roller 11, the contact surface between the packaging bag and the first roller 11 can be increased, making the packaging bag more stable during conveying. When the first roller 11 rotates, the bristles 51 contact the surface of the first roller 11 from below. As the first roller 11 rotates, the third roller 5 rotates at the same time. At this time, the bristles 51 can sweep the surface of the first roller 11, sweeping away the dust and particulate impurities adhering to the surface of the first roller 11. Some of the dust and particulate impurities swept away from the surface of the first roller 11 will fall into the drawer 61 below and be collected. After collection, the drawer 61 is taken out from the collection groove 6, the dust and impurities are poured out, and then the drawer 61 is put back into the collection groove 6. When the airflow enters the air guide hood 32, it will pass through the filter plate 7. At this time, the filter plate 7 will filter the airflow, filtering out the dust and impurities in the airflow. After filtration, the filter plate 7 can be removed, cleaned, and then reinstalled. When the packaging bag is conveyed with the surface of the second roller 13, the packaging bag will contact the rubber pad 8.
