double-layer automatic bagging machine for packaging hollow plastic containers is involved.

It comprises two sets of conveying modules arranged front-to-back, with each set consisting of two conveying structures distributed left-to-right. Each conveying structure includes a bow-shaped fixed frame, inside which two conveyor shafts are rotatably mounted on the upper and lower sides. Conveyor belts are laid over the two conveyor shafts. Two sets of gripping structures are arranged on the outer surface of the conveyor belts, positioned diagonally relative to each other. By performing automatic dual-bag packaging of plastic containers, this system effectively simplifies the packaging process, reduces labor requirements, and enhances operational efficiency. It also prevents tearing or damage to packaging bags that may occur during manual packaging, thereby improving packaging quality.
