Anti-blocking device for exhaust port of double-screw extruder

Abstract

The utility model relates to anti -blocking device technical field discloses a kind of exhaust port anti -blocking device of double-screw extruder, including double-screw extruder, fixed cover is fixedly installed on the double-screw extruder, the top of fixed cover is fixedly connected with connecting cover. The utility model can drive rotating rod drive control shaft rotation by starting drive motor, control shaft rotation can control connecting block to drive movable rod to do up-down reciprocating motion in limiting groove, movable rod can drive dredging block to move up and down, when dredging block moves down, it will be inserted into exhaust groove, when there is processing object in exhaust groove and causes blockage, processing object will be pushed back into double-screw extruder by dredging block to dredge exhaust groove, when cleaning operation is carried out in dredging block, three exhaust grooves are not blocked simultaneously, ensure the stable discharge of excess gas in double-screw extruder, so as to avoid the exhaust port being blocked by processing object, gas cannot be discharged from machine, affect the quality of product.
