Active high-speed carton opening mechanism suitable for large carton and control method

The invention proposes an active high-speed carton opening mechanism suitable for a large carton and a control method. The carton opening mechanism comprises a fixing frame, a driving control mechanism and a forming mechanism, wherein the driving control mechanism is installed on a rail at the top of the fixing frame through screws, and the forming mechanism is installed on the lower surface of the driving control mechanism; a speed reduction motor is used for driving, the speed is high, and 90-degree completion from carton suction to carton opening only needs about 2 seconds; active carton opening and carton sucking and opening are achieved in one step through suction cups, the automatic carton opening requirement of large cartons can be met, the problems that traditional equipment is unstable in carton opening, and cartons are opened incorrectly are solved, the carton damage rate is reduced, the enterprise production and maintenance cost is saved, meanwhile, the carton opening speedis remarkably increased,
