Dust hood device for main roller laser processing

The invention provides a dust hood device for laser processing of a main roller, which is characterized by comprising a laser head, a dust hood is arranged between the laser head and the main roller, the dust hood comprises a hood body, one end of the hood body is a connecting end, and the other end of the hood body is an open end. The connecting end is fixedly connected with the laser head and is kept to be coaxially connected with a laser path of the laser head, a light beam emitted by the laser head reaches the surface of the main roller through a cavity formed in the cover body, and the opening outline of the opening end is suitable for being in butt joint with or wrapping the roller surface on the periphery of an instant laser processing area of the main roller. 本发明提供了一种用于主辊激光加工的吸尘罩装置，其特点为，包括一激光头，所述激光头与主辊间设有一吸尘罩，所述吸尘罩包括一罩体，所述罩体的一端为连接端，另一端为开口端，所述连接端与所述激光头连接固定并保持与激光头光路同轴连接，所述激光头发出的光束经所述罩体内部形成的腔室到达主辊表面，所述开口端的开口轮廓适宜于对接或包覆所述主辊即时激光加工区域外围的辊面。
