Abstract

This invention discloses a twin-screw structure for continuous polymer reaction molding, relating to the field of twin-screw extruders. To address the problems of existing devices being bulky during use and prone to polymer residue buildup during stirring, making cleaning difficult, this invention provides a twin-screw structure for continuous polymer reaction molding. The structure includes a cylindrical body with a top plate mounted on it. A rotating mechanism is mounted on the top plate and connected to a twin-screw mechanism via the top plate. The twin-screw mechanism is mounted on a moving mechanism, which is mounted on a base plate. A lifting mechanism is mounted on the lower surface of the base plate and fixed to the bottom of a mounting slot, which is located on a base. This twin-screw structure for continuous polymer reaction molding is simple in structure, allowing for continuous polymer reaction during rotation, improving reaction efficiency, facilitating the cleaning of polymer residue adhering to the helical blades, and utilizing the soft rubber material to prevent damage to the helical blades.
