Transiting at Shanghai Pudong on separate airline tickets

I plan to transit at Shanghai Pudong in November using two separate airline tickets. 1) Madrid/ Shanghai Pudong & then Shanghai Pudong/Auckland. The two flights are paid for and ticketed separately - both are confirmed with confirmed seats.

This means I will need to enter China, collect my luggage, catch a few hours sleep in a airport hotel room (if possible) and then proceed to departures to check-in for the second flight.

I am travelling on a Spanish passport.

Can you please confirm that I am eligible for either a 72 hour or 144 hour transit visa that I can apply for on arrival?

I require confirmation as there are forums on other websites saying that as of late Chinese immigration has been refusing entry to passengers in this situation.
