Abstract
A double screw cutter for recycled carbon fiber material and a method of cutting recycled carbon fiber material by using the same are provided. The double screw cutter includes a housing and counter-rotating twin screws. A cut channel is formed in the housing while a long-fiber feed inlet, a mid-fiber feed inlet, and a short-fiber feed inlet are disposed on an outer surface of the housing and all communicated with the cut channel. A discharge outlet is arranged at a rear end of the housing and communicated with the cut channel. The counter-rotating twin screws are mounted in the cut channel of the housing and provided with two screw rods rotated in opposite directions simultaneously. Thereby recycled carbon fiber with different lengths is cut into a preset length and thus the following processes and applications of the recycled carbon fiber become more convenient.
