NOVELTY - The utility model relates to a PU graphene moisture-permeable film production technology field, and claims a quantitative feeding device for producing PU graphene comprising a mixing tank, the outer surface of the first feeding port is connected with a cylinder, the inner part of the cylinder is movably provided with a sponge floating plate, the outer surface of the top part of the sponge floating plate is fixedly connected with a supporting rod, the outer surface of the top part of the supporting rod is fixedly connected with a trapezoidal blocking block, the inner surface of the feeding box is movably connected with a rotating plate, the outer surface of the top part of the rotating plate is fixedly connected with a rotating rod, the inner surface of the rotating plate is provided with a through hole. The quantitative feeding device for producing PU graphene moisture-permeable film, the floating plate drives the supporting rod and the trapezoidal block, so as to quantify the chloroform, through the rotating rod to rotating plate, and then matched with the second feeding port through the through hole, so as to measure the amount of the anti-ultraviolet agent, It reaches the effect of quantitative feeding and can adjust the amount of the raw material according to the need.
