Mechanism capable of automatically feeding outer packaging bags and automatically printing codes at same time

The utility model discloses a mechanism capable of automatically feeding outer packaging bags and automatically printing codes at the same time, outer bags to be packaged in batches are flatly placed inside an outer bag placing assembly, a 90-degree grabbing assembly is pushed by a linear module to turn over by 90 degrees along a 90-degree turnover groove to slide downwards, a vacuum suction cup sucks the outer bags, and the outer bags are placed on the outer bag placing assembly. The straight line module pulls the 90-degree grabbing assembly to overturn upwards by 90 degrees along the 90-degree overturning groove, an outer bag is placed into the code printing rolling system, after the code printing contact system presses the outer bag, a set bar code is printed on the outer bag, the whole action process is automatic, the mechanism is ingenious in overall conception and efficient and smooth in action rhythm, a large amount of manpower of traditional packaging is reduced, and the production efficiency is impro
