The invention discloses automatic blanking packing bag continuity machining equipment. The automatic blanking packing bag continuity machining equipment comprises a pressing-type platform, a first pressing strip, a second pressing strip, a third pressing strip, an upper pressing plate, a material discharging roller set, a waste material wind-up roller, a rack, an output mechanism, a first driving mechanism, a second driving mechanism and a third driving mechanism. An edge sealing groove and a punching blanking groove are formed in the pressing-type platform in sequence. The material discharging roller set and the waste material wind-up roller are located at the two ends of the pressing-type platform respectively, are arranged on the rack and are both driven by the third driving mechanism. The material discharging roller set comprises a first material discharging roller and a second material discharging roller. The first pressing strip, the second pressing strip and the third pressing strip are all located above the pressing-type platform and are all driven by the first driving mechanism. The upper pressing plate is located above the pressing-type platform and is driven by the second driving mechanism. A pressing head and a punching head are arranged at one end, closing to the pressing-type platform, of the upper pressing plate. The output mechanism is located below the punching blanking groove and is used for gathering falling materials punched by the punching head and conveying the falling materials out. According to the automatic blanking packing bag continuity machining equipment, the production efficiency of packing bags is improved greatly.
