You can use the Luxury Ball and the Soothe Bell together to increase the boost. Each one boosts Friendship gained by 1 point, and combined will increase Friendship by 2 points each time it is raised.
Try to do all of your healing at a Pokémon Center or healing with normal healing items, which won’t have any effect on Chansey’s Friendship level.
If the evolution into Blissey does not happen, Chansey’s Friendship is not high enough. Continue increasing its Friendship.
