Follow-up smoke exhaust device of laser cutting machine

The invention relates to the technical field of laser cutting, in particular to a laser cutting machine follow-up smoke exhaust device which comprises a cutting machine body, a supporting frame, a laser cutting end and a smoke exhaust mechanism. The cutting machine body is arranged on the ground, and the upper end of the cutting machine body is connected with the supporting frame of an inverted-U-shaped structure through a longitudinal electric sliding block; according to the laser cutting machine, the design concept of removing smoke through multi-flushing and multi-suction is adopted, the whole laser cutting machine is of a housing structure, the cutting point of a cutting material is always located in the housing structure, and the cutting point of the cutting material is located in the housing structure; by means of the housing structure, smoke generated by laser cutting cannot be quickly and massively scattered into the working environment, workers can be effectively prevented from inhaling the smoke, th
