Technical Field
[0001] The utility model relates to the technical field of twin-screw extruders, in particular to a novel twin-screw extruder. Background Art
[0002] A twin-screw extruder is a device used for extrusion processing of materials such as plastics, rubber, and food. It plasticizes and extrude materials by rotating two screws at the same time. Twin-screw extruders usually have higher production capacity and better mixing effect than single-screw extruders. There are at least the following disadvantages in the use of existing twin-screw extruders: 1. During the use of existing twin-screw extruders, the feed port is mostly set above the barrel, resulting in the feed port being too high. When adding materials, the staff needs to climb up and then move the materials to the feed port before adding them. This is not only cumbersome to operate, but also poses a safety risk; 2. During the use of existing twin-screw extruders, the discharge port is mostly a fixed structure, which cannot be adjusted according to the size of the discharge material according to the use requirements, affecting the convenience of use. Therefore, we have launched a new type of twin-screw extruder. Utility Model Content
