Problems solved by technology

[0002] In the process of plastic processing, it is necessary to use an extruder to squeeze the plastic into the mold. The extruder relies on the pressure and shear force generated by the rotation of the screw, which can fully plasticize and mix the material, and then shape it through the die. , but the working efficiency of the traditional extruder is low, and the speed of the screw is lower than the preset speed due to the accumulation of raw materials at the discharge port
[0003] In order to solve the above problems, the existing patent announcement number is CN105881867A patent has announced a kind of extruder, but this kind of device has disadvantages in the process of implementation, which causes the material to be delivered with hysteresis. In the second extrusion chamber, after the operation of the first extrusion chamber is completed, the material in the second extrusion chamber needs to be squeezed into the first extrusion chamber before the second extrusion can be carried out, so that there will be more in the middle A procedure, which in turn reduces the output speed
