Any suggestions locker for a bulky luggage at Baiyun Airport

I and my family (6 pax with 12 bulky luggage) will arrive at 3 pm at the airport and will stay at Guangzhou Hotel for a couple of day.

I prefer to put all the luggage at airport locker. Is there any locker for me in the airport? If there's any, how much it cost for 1 day? Because after 2 Days we will continue our traveling to another destination.
