摘要： A composite filament melt impregnation device with an automatic lifting channel for additive manufacturing includes a mechanical lifting device, a heating device, a curved resin impregnation channel, a filament guide block, a single screw extruder, a replaceable combination die nozzle, and a resin riser. The composite filament melt impregnation device can significantly improve the efficiency of replacing filaments and treating broken filaments in a forming process of continuous fiber filaments, reduce the operation difficulty of a production process, and ensure the safety of operators. The design of the resin riser can achieve slight dynamic adjustment of pressure in a melt cavity in the production process, improve the stability of product quality, and ultimately achieve continuous production and rapid replacement of high-performance continuous fiber composites.
