Problems solved by technology

[0002] As we all know, the extruders currently used in plastic or rubber processing include parallel co-rotating twin-screw extruders, parallel counter-rotating twin-screw extruders and conical counter-rotating twin-screw extruders; parallel co-rotating twin-screw extruders The advantage of the extruder is that it has good plasticizing performance, but its disadvantages are that the extrusion force is small, the structure of the deceleration distribution box is complicated, and the power consumption is large; while the parallel counter-rotating twin-screw extruder is not good in plasticizing performance and extrusion force; and The advantage of the conical counter-rotating twin-screw extruder is that the extrusion force is large, and the disadvantage is that the plasticizing performance is poor, so it is not satisfactory in actual use. It seems that the plasticizing performance and the extrusion force in the extruder become the same Contradiction
We know that poor plasticizing performance will directly affect the quality of the plasticized product, and the extrusion force will affect the output and cost. Therefore, can we design an extruder that integrates the above advantages and eliminates its disadvantages? , to break through the defects of the current extruder and update the processing capacity of the equipment, it seems to have very important economic value and application value
