Export Artworks per Batch/Droplet

Have any idea how can export the artworks/canvas in photoshop automatically per batch/droplet/script function?

I created a script what import a multiple layer document, create another multiple layers and update an other multiple artworks/canvas photoshop document. The last part to export the artworks/canvas is not possible because this not exist in photoshop. I can put the menu ("Export as ...) but this open only the dialog and do not export the artworks. 

Which would be great too if I have a function that save the name of the first psd and put this in the artworks as suffix or as a prefix.

Background:

My client needs an automation per one click to generate jpgs of a multiple artworks/canvas photoshop document. I created for a client basically two files. The first psd has many designs in one photoshop document what has multiple artworks/canvas. The second psd is a smart object and it is connect with the first document. This smart object paste and generate per script from client the multiple layer photoshop document an create different design versions what then update the multiple artworks/canvas.
