A movable support is mounted on the guide rail and driven by a drive mechanism to move horizontally back and forth along the guide rail. The movable support has an upper crossbar and a lower crossbar, which are perpendicular to the support plate and parallel to each other. The upper and lower crossbars are moved up and down by a lifting mechanism. Suction cups are mounted on the upper and lower crossbars respectively to hold the opening of the packaging bag fed by the bag feeder and open the bag opening by the lifting mechanism.

[0006] A further aspect of the solution is as follows: a rectangular slot is provided on the support plate, and two guide rails are respectively located at the upper and lower ends of the rectangular slot on one side of the support plate. The driving mechanism includes a toothed belt, gears, and a drive motor.

One of the gears 5 is sleeved on the rotating shaft of the drive motor 6. A clamp 7 is clamped on the toothed belt 4 and is connected and fixed to the movable support 3. The rotating shaft of the motor 6 drives the toothed belt 4 to rotate through the gear 5. The rotating toothed belt 4 drives the movable support 3 to move horizontally back and forth along the guide rail 2 through the clamp 7.

[0014] Wherein: the suction cup 303 has at least two suction cups arranged side by side on each of the upper and lower crossbars.

[0015] In this embodiment, the movable support 3 is an upright plate, and the lifting mechanism includes a vertical guide rail 304, an upper mounting base plate 305, a lower mounting base plate 306, and a clamping guide block 307 mounted on the upright plate.
