Abstract

The invention discloses a filament cutoff device of a continuous fiber reinforced composite 3D printer. The filament cutoff device comprises a filament conveying cylinder, the lower end of the filament conveying cylinder is fixedly connected with a nozzle, the outer surface of the filament conveying cylinder is connected with a cutting assembly in a sleeved manner, the cutting assembly comprises a fixed shaft, the lower end of the fixed shaft is fixedly connected with a base plate, a cutter is fixedly connected to the front side of the base plate, and a cleaning driving piece is arranged on the lower surface of the base plate. The invention relates to the technical field of 3D printers. According to the filament cutoff device of the continuous fiber reinforced composite 3D printer, the cutting assembly is arranged, after printing of the 3D printer is completed, the cutter can automatically cut off filaments on the nozzle under the work of an electric push rod, and therefore subsequent printing work of the 3D printer is facilitated, manual cutting is not needed, the safety performance is improved, under the elasticity of a second spring, after the filaments are cut off, the cutter can automatically return to the original position, and normal printing work of the nozzle of the 3D printer is not hindered.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a fiber filament cutting device for a continuous fiber reinforced composite material 3D printer. Background technique [0002] 3D printer, a machine of rapid prototyping technology, is a technology based on a digital model file, using bondable materials such as powdered metal or plastic, to construct objects by layer-by-layer printing, continuous fiber reinforced composite The material has superior physical and mechanical properties. It not only greatly improves the mechanical properties of composite materials, but also has the advantages of light weight, good overall design, recycling ability and strong absorption of external energy. 3D printers often use continuous fiber reinforcement. Composite materials for printing jobs. [0003] However, after the current 3D printer is printed, the fibers on the 3D printer need to be cut off manually, which is very troublesome. Althoug...
