[0002] An extruder is a type of production equipment used to extrude materials into strips or specific shapes. It is widely used in industries such as food processing, plastic products, and ceramic manufacturing. An extruder usually consists of a feeding device, an extrusion screw, a heating system, and a mold. By controlling the temperature and pressure of the material, it ensures that the extruded strip products have uniform size and good molding effect.
[0003] The nut and lead screw in the extruder are key components for achieving precise control and stable operation of the extruder. They constitute the transmission system of the extruder and are responsible for converting rotational motion into linear motion, thereby realizing the feeding and adjustment functions of the extruder. However, the existing nut and lead screw will wear out after long-term use, resulting in an increase in the transmission gap, affecting the accuracy and stability of the extruder, and replacing severely worn nut or lead screw requires high cost and time investment.

[0006] As an improvement, the outer diameter of the mounting platform is smaller than the outer diameter of the main body;
[0007] As an improvement, the outer diameter of the boss 1 is larger than the outer diameter of the main body 1;
[0008] As an improvement, the inner diameter of the thread 1 is larger than the outer diameter of the main body 1, and the outer diameter is smaller than the outer diameter of the boss 1, and spaces are left between the ends of the main body 1 and the side of the boss 1 respectively;
[0009] As an improvement, one side of the socket matches the outer diameter of thread one, and the other side matches the outer diameter of body one;
[0010] As an improvement, the outer diameter of the boss 2 is larger than the outer diameter of the body 2;
[0011] As an improvement, the outer diameter of the reinforcing platform is larger than the outer diameter of the main body 2 and smaller than the outer diameter of the boss 2;
[0012] As an improvement, the inner diameter of the second thread is larger than the outer diameter of the second body, and the outer diameter is smaller than the outer diameter of the reinforcing platform;
[0013] As an improvement, the outer diameter of the thread three is smaller than the outer diameter of the body two.
