Care About Components of Rubber Extruder Machine


a screw rod 4 having an inner section 45 that extends co-axially through the opposite end 212 of the cylindrical barrel 21 and into the cylindrical barrel 21 and that has an abutting end 41 adapted to abut against the rubber material

.

 

The rubber extruder machine includes: a fixed cylindrical barrel 21 adapted to receive a rubber material and having a die end 211 and an opposite end 212 opposite to the die end 211; an extrusion die 25 mounted in the die end 211 of the cylindrical barrel 21; a screw rod 4 having an inner section 45 that extends co-axially through the opposite end 212 of the cylindrical barrel 21 and into the cylindrical barrel 21 and that has an abutting end 41 adapted to abut against the rubber material, and an outer section 47 that extends axially from the inner section 45 and that is disposed outwardly of the cylindrical barrel 21, the screw rod 4 being movable in an axial direction relative to the cylindrical barrel 21 so as to extrude the rubber material through the extrusion die 25; a coupling unit 3 including a threaded sleeve 33 that is sleeved rotatably on and that engages threadedly the outer section 47 of the screw rod 4; a fixed limiting member 51 in constant engagement with the screw rod 4 in such a manner that rotation of the threaded sleeve 33 results in axial movement of the screw rod 4 relative to the cylindrical barrel 21; and a driving unit 6 for rotating the threaded sleeve 33.
