NOVELTY - The utility model claims a modified extruding device for preparing graphene colour master batch. The modified extruding device for preparing graphene color master batch comprises a base; the top of the base is fixedly connected with a processing box through a first mounting base; the top of the processing box is fixedly connected with a mixing barrel through a second mounting base; the bottom of the mixing barrel is connected with a discharging pipe; one end of the discharging pipe passes through the processing box and extends to the inner part of the processing box. The modified extruding device for preparing graphene color master batch provided by the utility model uses the air pressure to push the sealing rubber pad to extrude the material, then using the negative pressure to reset the sealing rubber pad to repeatedly use, improving the production efficiency, and will not cause the retention of the material, will not affect the device for multiple times, When the material production is uniformly mixed, the material attached on the inner wall of the mixing barrel can be scraped down and stirred again; the raw material is fully mixed, which improves the production quality and improves the production efficiency.
