A carton erecting machine is an automated packaging device designed for unfolding and forming folded cartons, primarily used to open, shape, and seal the bottom of boxes. It is widely applied in production lines across industries such as food, pharmaceuticals, electronics, and consumer goods. The standard workflow involves manually or automatically placing flat carton blanks into the machine's hopper, where the device performs suction, unfolding, side flap folding, and bottom sealing (with tape or hot melt glue) to rapidly form empty cartons for subsequent filling and sealing processes.

By automation level, carton erecting machines are classified into semi-automatic (requiring manual feeding/adjustment, suitable for small-to-medium output) and fully automatic (integrated with conveyor systems for automated blank feeding, forming, and sealing, significantly improving efficiency). Utilizing pneumatic or mechanical transmission, these machines ensure precise positioning, high-speed operation, and uniform carton formation, adaptable to various carton sizes (with mold changes) while reducing labor intensity and errors.

With smart manufacturing advancements, advanced models now incorporate intelligent detection (e.g., blank absence alerts, sealing defect recognition) and servo motor drives, enhancing stability and compatibility. As a critical front-end automation solution in modern packaging lines, they optimize logistics and packaging workflows.
