Title:
FILAMENT MELT IMPREGNATION DEVICE HAVING AUTOMATICALLY-LIFTABLE FLOW CHANNEL USED FOR ADDITIVE MANUFACTURING
Document Type and Number:
WIPO Patent Application WO/2023/216421
Kind Code:
A1
Abstract:
Disclosed in the present invention is a composite material filament melt impregnation device having an automatically-liftable flow channel used for additive manufacturing, which comprises a mechanically lifting device, a heating device, a curved resin impregnation flow channel, a filament-guiding block, a single-screw extruder, a replaceable combined mold nozzle and a resin riser. The present invention can greatly improve the efficiency of replacing filaments and dealing with broken filaments during a continuous fiber filament forming process, thereby reducing the operation difficulty in the production process and guaranteeing the safety of operators. By designing the resin riser, the internal pressure of a melt cavity can be dynamically adjusted within a small range during the production process, so that the product quality stability is improved, and finally, the continuous production and rapid replacement of high-performance continuous fiber composite material filaments are achieved.
