Abstract

This utility model discloses an automatic fume extraction welding machine, including a welding head, a fume extraction assembly, and a fume extraction pipe. The fume extraction assembly achieves efficient airflow acceleration through magnetic drive of a vortex impeller and an excitation assembly. The cooperation of a fixed-rotation ring and a shaft sleeve guides the airflow and accelerates fume emission. A grid ring and a heat-insulating kit further improve fume filtration efficiency, ensuring effective removal of harmful substances from welding fumes. This utility model, by employing vortex impeller and magnetic drive technology, not only improves the fume extraction effect but also significantly reduces energy consumption and noise, offering advantages such as high efficiency, energy saving, and environmental friendliness. Simultaneously, it simplifies the equipment structure, facilitating cleaning and maintenance, and is suitable for various welding operations, especially in environments with strict requirements for welding fume extraction.
