Abstract

The invention discloses a circulating water loading device for high-speed optical fiber secondary coating. The circulating water loading device comprises a cold water machine used for active refrigeration, a cold water tank and a plurality of cold water interfaces which are matched with cooling water tanks in number of a plastic extruding machine for high-speed optical fiber secondary coating, wherein the cold water machine is provided with a water inlet, a refrigerator and a water outlet, cooling water flowing into the water inlet flows out from the water outlet after being cooled through therefrigerator, and the water outlet communicates with an water inlet of the cold water tank; and the cold water tank communicates with the cooling water tank through the plurality of cold water interfaces. The invention further provides a secondary coating cooling method. The cooling method is characterized in that when the temperature of the cooling water tank is higher than the corresponding preset temperature range, cold water is supplied through the corresponding cold water interface, and the temperature of the cooling water tank is controlled to be within a corresponding preset temperature range. The circulating water loading device for high-speed optical fiber secondary coating is low in equipment investment, low in research and development cost, good in cooling effect and flexible to apply.
