The present invention discloses a structure for a co-rotating parallel twin-screw extruder, comprising a base. Above the base is mounted a barrel assembly, which includes an open barrel, a closed barrel, a side feed barrel, and an extrusion barrel. The barrels are positioned by locating pins and connected by connecting bolts. The barrel assembly is connected to a gear reducer via a barrel connector. The gear reducer is mounted above the base. Its input shaft connects to the motor output shaft via a coupling. Two parallel screws are installed within the barrel assembly. The screw shafts feature replaceable threaded sleeves and meshing blocks. The rear ends of the screw shafts connect to the gear reducer's dual output shafts via spline sleeves. This structure facilitates disassembly and assembly. The main components of the barrel assembly and screw assembly exhibit good interchangeability. Their combination and mounting positions can be adjusted according to the process requirements for modifying, polymerizing, reacting, and extruding polymer materials, thereby achieving the objectives of enhancing operational efficiency and boosting enterprise production benefits.
