NOVELTY - The utility model relates to the technical field of sizing sleeve, especially relates to a sizing sleeve for producing graphene floor heating pipe, the technical solution comprises: a lower sleeve, a water distributing ring and an upper sleeve, the upper end of the lower sleeve is connected with an upper sleeve, the outer wall of the upper sleeve is clamped with a flange, the flange is annularly arranged with a second through hole, the inner part of the second through hole is inserted with a fixing bolt, the upper surface of the flange is installed with a water distributing ring through the fixing bolt, the outer wall of two ends of the water distributing ring is provided with a connecting pipe, the outer wall of the upper sleeve is embedded with a spiral pipe, the central distance of the spiral pipe is provided with a water outlet hole. The utility model can make the cooling water in the spiral pipe enter between the water distribution ring and the upper sleeve through the water outlet hole, so that the cooling water in the spiral pipe is quickly and circularly replaced, at the same time, the two connecting pipes can synchronously introduce cooling water to the spiral pipe, so that the cooling water temperature at two ends of the water distribution ring in the sizing sleeve is the same, The cooling effect of the device is greatly improved.
