The invention relates to the field of plastic recycling and reuse, in particular to a method and a device for separating ink from plastic recycled materials with an ink layer. The ink separation method is characterized by comprising the following steps: Step 1: heating the recycled material of thermoplastic material with an ink layer to destroy the adhesion of binders in the ink layer, obtaining a liquid recycled material mixed with ink and thermoplastic material; Step 2: filtering the liquid recycled material obtained in Step 1 through a filter to obtain a recycled material from which binders, partial colorants and other additives have been removed. Aiming at the deficiencies of the prior art, the invention designs an ink separation method and device for heavily dyed recycled plastics, which have low requirements on the pigment composition of recycled materials, no obvious requirements on the product color, or are suitable for recycled materials with single color composition that can be remade into products of the same color.
