By arranging the heat preservation mechanism 53, the side wall of the branch pipe 5 is heated through the work of the heat preservation mechanism, so that the temperature of the side wall of the branch pipe 5 is increased, the water vapor is prevented from being liquefied into liquid after entering the branch pipe 5, and the yield of resin plate sheets is improved.
