Carton sealing machines are mechanical devices used for sealing and packaging cardboard boxes, widely applied in industries such as home appliances, textiles, food, and pharmaceuticals. They can operate independently or integrate into assembly lines.

This equipment employs a continuous conveying system comprising a transport mechanism, sealing mechanism, and adjustment mechanism. It features a gravity-driven longitudinal centering bar for automatic carton alignment. The design incorporates a patented clamping device, buckle-style belt, and spring-driven blade holder, supporting integrated top and bottom sealing operations. Adjustable via a lifting handle and clamping rollers, it accommodates various carton dimensions. The first floating head folds the front flap, while the second floating head, equipped with a tape dispenser, performs adaptive sealing and strapping.
