I have a signal with a lot of peaks. what i want to achieve is to get the envelope of inner part of the signal, the one of that part that looks solid in colors not the peaks envelope is it possible to achieve this.

You could try different weights and lengths for the smoothing until you get something that looks like what you'd like. The easiest way however would probably be to ask the person that generated that plot.
To avoid giving much weight to the peaks, you could also try with a median filter:
