Abstract
A coupling device includes a pipe including at least pipes through which a molten resin passes, in which the coupling device couples an output device that outputs the molten resin to be recycled and an injection molding machine that performs injection molding of the molten resin with each other by connecting an upstream end part of the pipe to the output device and connecting a downstream end part of the pipe to the injection molding machine, and the coupling device includes, on a downstream side of the pipe, a removal dissolution unit that removes or dissolves a solid foreign matter mixed in the molten resin.
