AI Technical Summary
The electronic detection devices of existing FDM printing equipment are susceptible to the effects of printing environment temperature and dust, which can lead to detection failures and failure to provide timely feedback on abnormalities in the printhead material. This can result in material breakage and gaps in the printed layer, reducing the yield.
The device employs a mechanical structure with a baffle plate, push rod, and compression spring working in tandem. The detection is directly driven by the extrusion pressure of the molten material, enabling instantaneous feedback of material shortages and interruptions, thus avoiding signal transmission delays. This includes the baffle plate rotating inside the print head, which in turn drives the push rod and indicator plate, providing intuitive visual detection.
It can achieve stable and durable material shortage detection without the need for circuits and sensors, improving the continuity of the printing process and the yield rate, and avoiding detection failure caused by electronic equipment failure.
