Conical parallel dual-screw extruding machine

Abstract

The invention discloses a conical co-rotating twin-screw extruder, which consists of a drive motor (1), a coupling (2), a deceleration distribution box (3), a feeding system (4), and a barrel (5) , conical twin-screw (6), exhaust system (7), pelletizing system (8), hopper (9), etc., and there are two main conical screws rotating in the same direction in the barrel (5) (6-1) and secondary conical screw (6-2), which are respectively connected with the driving gear (11) and the driven gear (13) in the deceleration distribution box (3), there is also a gear below the second gear Intermediate gear (12), so that the conical twin-screws keep rotating in the same direction during work, and the helixes of the conical twin-screws also rotate in the same direction; this will improve the plasticizing performance of the present invention, and the good extrusion performance, so that the present invention has both good extrusion force and good plasticity, suitable for extrusion and granulation in plastic processing, which improves output and reduces energy consumption. It is suitable for various plastics and rubber processing. new extruder.

Description

technical field [0001] The invention discloses a conical twin-screw extruder suitable for extrusion and granulation used in plastic or rubber processing. Background technique [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 disadvantage is that the extrusion force is small, the structure of the deceleration distribution box is complex and the power consumption is large; while the parallel counter-rotating twin-screw extruder is not good in plasticizing performance and extrusion force; 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 sat...

[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
