Method and device for preparing consumable material of continuous fiber bundles

Abstract

The invention discloses a method and device for preparing a 3D printing linear material of a continuous fiber bundle reinforced composite material. The device comprises a motor, a feeding device, an extrusion molding device, a cooling device, a traction machine and a wire winding device, wherein an extrusion head forming mold of the extrusion molding device comprises a mold sleeve, a mold core and a mold head which are sequentially arranged in the feeding direction, continuous fiber bundles are arranged inside a center cavity after the mold core and the mold head are nested, the heated molten polymer raw material are fed from a feeding hole of the mold sleeve through extrusion so as to wrap the continuous fiber bundles, the diameter of an extruding object is adjusted by adjusting the traction force and the traction speed of the traction machine, and then the extruding object is collected through the air cooling device and the winding device to obtain the continuous fiber bundle 3D printing linear consumable material. The preparation device of the continuous fiber bundle 3D printing linear material is reasonable in structure and can realize industrial production of the 3D printing linear material of the continuous fiber bundle reinforced composite material, the processing technology is simple, the structures of the continuous fiber bundles cannot be damaged, the linear material forming effect is good, the operation is convenient, the production efficiency is improved, and the production cost is saved.

Problems solved by technology

At present, 3D printing consumables are mainly engineering plastics, photosensitive resins, rubber materials, metal materials, ceramic materials, gypsum materials and other wire materials. Currently, ABS and PLA are generally two types of printing wire materials. For short fiber 3D Printing consumables are relatively mature, but the mechanical properties of all consumable molding components are still limited, which limits their industrial application range and cannot meet the needs of 3D printing technology market development
