Davies had a chat with Earnshaw on Monday and is confident the player will soon be making a key contribution.
"Rob is a 'box striker' but you know when you go to these places the chances you get will be few and far between.
"I spoke to him and explained the situation. He has not been brought to this club just to play in the first seven games, he has been brought here to take part in the club's progression over the next number of years.
"He is finding his feet, but I am totally convinced that the lad will very soon be firing on all cylinders and scoring goals.
"Looking at the run of games coming up, I certainly see him starting to come more into frame."
