NOVELTY - The utility model claims a pre-treatment clamp for graphene, belonging to the technical field of clamp, the device comprises an inner drum, and an upper shell and a lower shell sleeved on the outer side of the inner drum; the inner winding drum is provided with two first circulating liquid interfaces; the upper shell and the lower shell are both provided with two second circulating liquid interfaces; the first circulating liquid interface is set through the upper shell or the lower shell; an inner reel, the upper shell and the lower shell are provided with air holes; by injecting the liquid with constant temperature into the inner drum sleeved with each other, the inner part of the upper shell and the lower shell, namely can provide a constant temperature condition for the graphene material wound on the inner drum, and then matched with the vent hole, the gas generated in the pre-processing can be discharged; effectively solves the problem that the pre-processing clamp, easy temperature fluctuation is large, and the gas discharge is not smooth and caused by the graphene of cracking and layering.
