It has the characteristics of simple and reliable structure and high production efficiency. Since there are many applicable products for the screw extruder, and the enterprise arranges production according to order requirements, the products produced by the screw extruder will also change with the order requirements. When the screw extruder encounters material change, the cavity and the screw need to be cleaned. At present, the common method in the industry is to use cleaning materials to clean the extruder. If necessary, the screw needs to be removed and cleaned separately to ensure the cleaning effect and avoid the residual materials on the surface of the cavity and the screw from affecting the production quality of the product. Compared with the smooth inner wall of the cavity, the screw is easy to clean. Due to the complex surface structure and the location inside the cavity, and the parts (drive motor and forming mold) are blocked in front and behind, the screw is difficult to disassemble and the process is slow. In addition, because the screw is a precision component in the extruder, in order to avoid damage from bumps, it requires the cooperation of multiple people during disassembly, and the whole process requires a lot of manpower costs. Therefore, there is a certain market demand for designing a screw extruder that can be easily cleaned. Summary of the invention
