The invention discloses an integrated automatic bag making machine. Printing template cylinders are arranged on auxiliary printing cylinders, and printing brushes are fixedly arranged on the peripheries of the rotating circumferences of the printing template cylinders. Printing film rolling racks and inner film rolling racks are mounted on the two sides of printing pairs respectively. Film coating cylinder pairs are fixedly connected below the auxiliary printing cylinders, and strip-shaped nozzles are fixedly connected between film coating cylinders and the auxiliary printing cylinders. Heating bodies are arranged in the film coating cylinders, electric conducting slip rings are arranged at the ends of the film coating cylinders, and carbon brushes are pressed on the electric conduction slip rings. A bag making cylinder pair is mounted in the middle below the two sets of film coating cylinder pairs. The circumferences of bag making cylinders are longitudinally and fixedly provided with a cutter higher than the circumference or a cutting groove, the cutter and the cutting groove are oppositely mounted, and an oblique joint plate is mounted below the bag making cylinder pair. After the integrated automatic bag making machine which is simple in structure and convenient to manufacture is adopted, bag making is quick and convenient, and printing, film coating and bag making are coherent; automatic binning can be achieved, so that the bag making cost is reduced, production efficiency is improved, and the integrated automatic bag making machine is suitable for industrial production to make double-bag packing bags.
