The invention discloses a bundling and plastically-enveloping AIO (all-in-one) machine for paper currency used for automatically bundling and plastically-enveloping the paper currency, aiming at the different face values of paper currency in a financial system. The AIO machine mainly comprises an automatic bundling unit and an automatic plastically-enveloping unit, and is composed of a lower film rolling mechanism, a heat transfer printing printer, a paper currency adjusting mechanism, a primary pushing mechanism, an upper film rolling mechanism, a heat-seal bundling mechanism, a side pushing mechanism, an overturning mechanism, a film plastically-enveloping mechanism, a forming mechanism, a U-shaped sealing mechanism, a lifting mechanism, a material receiving mechanism, a thermoshrinking furnace mechanism and a PLC (Programmable Logic Controller) control system. The working principle of the AIO machine is that a start button is pressed and the primary pushing mechanism is controlled to push the paper current into the bundling mechanism for bundling through the PLC after 10 bundles of paper currency are placed into a paper currency entrance, and the paper currency is sent to a side push position through the overturning mechanism, the paper current is sent into the U-shaped sealing mechanism for plastically enveloping by the side pushing mechanism, and a packaging film is shrunk by the thermoshrinking furnace after the plastic envelope. The AIO machine has the advantages of being reasonable in structure, compact in mechanism, simple to operate, convenient to maintain, and realizing stability and reliability.
