Title:
CHAOTIC SINGLE-SCREW EXTRUSION INJECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/021146
Kind Code:
A1
Abstract:
A chaotic single-screw extrusion injection device, comprising a machine barrel (100) and a screw (200). The screw (200) is arranged in the machine barrel (100); and screw flights (210), first disturbance members (220) and second disturbance members (230) are arranged on the outer surface of the screw (200). The screw flights (210) spirally extend in the axial direction of the screw (200). One end of each first disturbance member (220) is connected to a thrust surface (201) of a screw flight (210); and the other end of each first disturbance member (220) extends in the direction towards a dragging surface (202) of a screw flight (210). One end of each second disturbance member (230) is connected to the dragging surface (202) of a screw flight (210); and the other end of each second disturbance member (230) extends in the direction towards the thrust surface (201) of a screw flight (210). The device can generate a longitudinal extrusion drawing flow field, and superpose a transverse circular flow effect in the cross section of screw channels, so as to induce a chaotic mixing enhancing effect, thus effectively enhancing the melt plasticizing and mixing efficiencies of materials while ensuring smooth flow channels. In addition, the first disturbance members (220) and the second disturbance members (230) generate a wedge-shaped pressurization enhancing effect in the axial section of the screw (200), so as to form an enhanced melting and mixing mechanism, thereby more effectively improving the melting and plasticizing efficiency of the screw (200).
