Paper packaging machine

The utility model provides a paper packaging machine comprising a frame, a surface paper wrapping bench, a long side surface paper laminator, a vertical member laminator, a short side surface paper laminator, an interior forming device, and an inside paper laminator. The frame is L-shaped and comprises a transverse plate, a vertical plate, a support plate, and a reinforcing connecting plate. The surface paper wrapping bench is perpendicularly mounted in the middle of the vertical plate. A surface paper wrapping main structure is a multilayer composite structure arranged on the support plate. The interior forming device is arranged below the surface paper wrapping bench and mounted on the upper portion of the vertical plate. An interior forming base is embedded on a guide rail of the vertical plate through a slider. The surface paper wrapping bench is in action fit with laminators for sides of openable boxes/bottom boxes, so that the automatic surface paper wrapping is achieved for the openable boxes/bottom boxes. Meanwhile, the labor consumption is effectively reduced, and the production efficiency is greatly improved. Moreover, the production cost is reduced and the economic benefit is improved.
