This utility model discloses a barrel cooling oil branching system for a twin-screw extruder, comprising a barrel, a compressor, an oil separator, a condenser, a dryer, an economizer and an evaporator. The oil outlet end of the barrel is fixedly connected with the oil inlet end of the compressor, the oil outlet end of the compressor is fixedly connected with the oil inlet end of the oil separator through a conduit, and the oil outlet end of the oil separator is fixedly connected with the oil inlet end of the condenser. The oil outlet end of the condenser is fixedly connected with the oil inlet end of the dryer through a conduit. The cooling oil inside the barrel of the utility model is compressed by the compressor and then separated by the oil separator. After condensation, drying and economizer treatment, the separated cooling oil is condensed twice by the evaporator and then flows back to the inside of the barrel again, which effectively ensures the cooling effect of the cooling oil inside the barrel, improves the stability of the screw extruder, and avoids the influence of excessive temperature on the service life of the screw extruder.
