AI Technical Summary
In existing 3D printer filament buffer mechanisms, the elastic telescopic component loses support during the maximum stroke of the filament, which can cause it to bend significantly, leading to filament accumulation and making it difficult to automatically stop feeding.
The design of inserting the inner material tube into the outer material tube ensures that the wire is always supported within the inner and outer material tubes, preventing excessive bending curvature. Friction is reduced by the guide tube and the limiting ring, and a detection component controls the feeding assembly to stop.
It effectively prevents the filament from accumulating in the buffer mechanism, ensures that the feeding component can stop in time, avoids excessive stretching or loosening of the filament, and improves printing stability.
