Then the material moves until it contacts the fixed plate. The rotating plate resets to limit the material position, thereby limiting the material's range of motion.

[0016] (2) The laser cutting device for steel structure production and processing drives the rotating rod 2 to rotate through the rotation of the gear, and the rotating rod 2 drives the protective plate to rotate until the protective plate rotates to cover the working area of ​​the cutting machine, effectively isolating the laser cutting area from the surrounding environment, preventing the laser beam from directly irradiating the eyes or skin of the operator, and reducing the safety risks caused by laser radiation. It can also prevent the heat and sparks splashed during metal cutting from injuring the operator. The protective plate contacts and squeezes the pull rod during rotation, and the pull rod opens under the action of the protective plate. Then the jet mechanism sprays the gas to the working area of ​​the cutting machine through the jet pipe, which helps to improve the cutting quality. It can also reduce the deposition of slag by cooling and cleaning the laser cutting head, effectively protect the laser cutting head and its lens, and extend the service life of the equipment. At the same time, under the action of the protective plate, it can prevent gas escape, maintain the gas environment of the cutting part, and improve the cutting effect.

[0017] (3) The laser cutting device used in the production and processing of steel structures drives the cleaning plate to move toward the conveyor belt by moving the cleaning rod. The cleaning plate uses the cleaning brush to brush off the welding slag on the surface of the conveyor belt, and promptly removes metal dust, welding slag and other residues generated during the laser cutting process to keep the surface of the conveyor belt clean. Then the scraper scrapes off the welding slag or impurities attached to the surface of the conveyor belt, effectively removing the welding slag and spatter generated during the cutting process, preventing them from accumulating on the surface of the conveyor belt and falling into the waste drawer. The waste is then processed by the staff in a centralized manner, avoiding the workers from being distracted to clean up the waste scattered in the work area during the busy work process. The centralized collection method can also improve the waste treatment efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
