The present utility model relates to the field of twin-screw extruders, and specifically discloses a twin-screw extruder for coating production, comprising a barrel. A feeding hopper is arranged on one side of the barrel, two extrusion screws are arranged in the barrel, extrusion screw flights are fixed outside the extrusion screws, a driving disc is fixed outside each extrusion screw, a first driving groove and a second driving groove are formed in the driving disc, a driving wheel is arranged at the top of the driving disc, a driving belt is sleeved outside the driving wheel and one of the driving discs, a driven belt is sleeved outside the two driving discs, the driving belt is located in the first driving groove, and the driven belt is located in the second driving groove. One motor drives the two driving discs to rotate simultaneously, realizing synchronous rotation of the two driving discs with consistent rotating speed and start-stop time. Compared with the conventional two sets of motors, the structure is simple and the control is efficient and stable. Moreover, the driving belt and driven belt produce lower noise during operation than conventional gears, and the replacement cost is lower.
