Weld-lie removal device of extrudate produced from two-way twin screw extruder

摘要

The present invention relates to a joint boundary removing device of the extrudate produced from the bidirectional twin screw extruder for preventing the bending caused by the joint boundary shown in the vertical direction on the extrusion sheet.;Conventional bi-directional twin screw extruder is a structure in which the breaker plate 9 is installed in the extruder barrel 7 and the die 10 is stretched to form a longitudinal junction boundary on the extruded molten resin so that the shape of the final product is not beautiful. There was a flaw.;Accordingly, the present invention provides a molten resin by installing a junction boundary removing device of the extrudate in which the molten flow split plate 2 of the twisted structure twisted at a predetermined angle is extruded between the extruder barrel 7 and the die 10. This is to change the flow from vertical to horizontal so that the end product will not bend due to the junction boundary.
