Extrusion cooling mechanism for cable insulation layer

The utility model discloses a cable insulation layer extrusion cooling mechanism, which relates to the technical field of cable processing and comprises a bottom plate, a water storage tank and a cooling assembly are fixedly mounted on the upper surface of the bottom plate, the cooling assembly is used for cooling a cable, a fixing block is fixed at the top of the water storage tank, and a pretreatment channel is fixed at the top of the fixing block. An end plate is fixed to the end, close to the cooling assembly, of the pretreatment channel and provided with a cable outlet groove for a cable to penetrate through. Water in a water storage tank is pumped into a transfer pipe through a water pump, the water is sprayed into a fixed pipe along a water spraying head on the transfer pipe, an air inlet fan guides outside air into the fixed pipe, air flow drives water drops to enter a pretreatment channel, and effective pre-cooling treatment is performed on a cable in the pretreatment channel; therefore, the prelimin
