This utility model discloses a screw structure for an extruder, belonging to the field of extruder technology. The structure includes a screw housed within a casing, comprising a first rod and a second rod rotatably connected to each other. A first gear set is connected to one side of the screw, and a second gear set is correspondingly located on one side of the first gear set. The second gear set is driven by a first cylinder to achieve displacement. The advantage of this utility model is that by driving the second gear set to displacement with the first cylinder, its meshing connection with the first gear set can be changed, thereby allowing the first and second rods to rotate independently at different speeds. This design can precisely optimize the speed matching of each section of the screw, effectively improving extrusion speed and yield, significantly enhancing the adaptability of the equipment to different production needs, and expanding its application range.
