Transfer from domestic flight to international one in Pudong, T2

Hello, I will arrive from Shenyang by domestic flight (CZ) and my next flight to Frankfurt is planned 2 h20min later. It's enough time to clear all formalities? I guess that I need to pick-up my baggage from baggage claim and after that to go for an international check-in and that takes a lot a time . The good news is that both flights are scheduled in T2.
Thanks for your answer
