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.
Claims11
A coupling device comprising:
- a pipe including at least pipes through which a molten resin passes,
- wherein 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,
- 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,
- the coupling device further comprises a coupling disposed in the pipe and configured to absorb relative movement between the output device and the injection molding machine, and
- the removal dissolution unit is disposed in the pipe on a downstream side of the coupling and on an upstream side of the injection molding machine.
A molten resin supply system comprising:
- an output device that includes an output port of which a position is fixed and that outputs a molten resin to be recycled from the output port;
- an injection molding machine that includes an input port of which a position is movable and that molds a molding product using the molten resin input through the input port;
- and
- a coupling device that includes a pipe through which the molten resin passes, that couples the output device and the injection molding machine with each other by connecting an upstream end part of the pipe to the output port and connecting a downstream end part of the pipe to the input port, and that 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,
- wherein the coupling device further includes a coupling disposed in the pipe and configured to absorb relative movement between the output device and the injection molding machine, and
- the removal dissolution unit is disposed in the pipe on a downstream side of the coupling and on an upstream side of the injection molding machine.
