By oscillating and adsorbing bags through the bag-standing mechanism 21, it ensures that only one bag is fed at a time, changing the bag from a horizontal to a vertical position before feeding it into the turntable mechanism. The bag-feeding mechanism 22, with its forward and backward movement, prevents interference with the turntable and avoids damage to the equipment.

[0056] The upright bag mechanism 21 includes: an upright column 211; a fixed base plate 212 mounted on the upright column 211; an upright bag shaft 213 rotatably mounted on the fixed base plate 212; a bag clamping arm 214, the first end of which is fixedly connected to the upright bag shaft 213; a bag clamping cylinder 216 mounted on the second end of the bag clamping arm 214, which can clamp the bag body; and an upright bag power mechanism that can drive the upright bag shaft 213 to rotate. The upright bag swing arm 215 drives the upright bag shaft 213 to rotate, and the upright bag shaft 213 drives the bag clamping arm 214 to swing, switching between a horizontal state and a vertical state. In the horizontal state, the bag clamping arm 214 moves to below the bag body, the bag clamping cylinder 216 clamps the bag body and sucks it out, and the bag clamping arm 214 rotates to the vertical state, thereby converting the bag body to a vertically placed position.

The first end of the stand-up bag swing arm 215 is fixedly connected to the stand-up bag rotating shaft 213, and the second end of the stand-up bag swing arm 215 is provided with a stand-up bag pull rod.
