The present utility model discloses a temperature measuring device for a twin-screw extruder, belonging to the field of extruders. The technical solution adopted is a temperature measuring device for a twin-screw extruder, comprising an extrusion mechanism with a feed end and a discharge end. Several groups of sealed shells are arranged on the outer wall of the extrusion mechanism at intervals from the feed end to the discharge end, a sealed heat exchange chamber is provided between the sealed shells and the outer wall of the extrusion mechanism, exhaust holes penetrating into the sealed heat exchange chamber are arranged on the sealed shells, an air duct is arranged on the extrusion mechanism, the air duct is connected with the exhaust holes through exhaust pipes, a temperature measuring component is arranged on the air duct, and an air guiding mechanism is arranged on the sealed shells. The present utility model is installed outside the extrusion mechanism through the sealed shells, facilitating later maintenance and protection of the extrusion mechanism, improving the service life of the extrusion mechanism, reducing the failure rate of the extrusion mechanism and lowering maintenance costs.
