Abstract

The invention belongs to the field of 3D printer structural design, and relates to a fiber cutting device for a continuous fiber reinforced composite material 3D printer. The device mainly comprises acutting mechanism and a clamping mechanism. The cutting mechanism drives a four-connecting-rod mechanism through a servo motor to drive blades at the tail ends of connecting rods to move to realize cutting of fibers. The clamping mechanism comprises an upper clamping mechanism and a lower clamping mechanism. When the cutting device works, the upper clamping mechanism and the lower clamping mechanism cooperate to realize clamping and fixation of continuous fibers; and the cutting mechanism realizes cutting of the fibers between the upper and lower clamping mechanisms. The device is simple in structure, can be assembled above a continuous fiber printing head to effectively reduce residues of the fibers after cutting, and improves the printing efficiency.

Description

technical field [0001] The invention belongs to the field of design and manufacture of 3D fusion printers, and in particular relates to a fiber filament cutting device for continuous fiber reinforced composite material 3D printers. Background technique [0002] 3D printing, also known as additive manufacturing, is based on three-dimensional CAD model data, using laser beams, hot-melt nozzles, light curing, etc. to sinter or bond metal powder, plastic and other materials layer by layer, and finally superimpose forming New manufacturing method. Among the 3D printing technologies, the fused deposition modeling technology is the most widely used, but due to the performance limitations of the printing materials, the printed parts often cannot meet the needs of actual use. In order to improve the mechanical properties of 3D printed parts, continuous fiber reinforced composite 3D printing technology has emerged. [0003] Studies have found that continuous fiber reinforced composi...
