Protective roof of fiber laser cutting machine

This is applicable to the new technology platform of the fiber laser cutting machine. It is a protective ceiling for the fiber laser cutting machine. It includes a U-shaped frame and a card board that is fixed at both ends of the U-shaped frame through screws; the U-shaped frame is vertical. The inner side wall of the directional section continuously has multiple guides that are continuously assembled, and the guide rods continue to the inner side wall of the U-shaped frame vertical section, the other end of the baffle is against the card board, and the two adjacent guide rods slide continuously in behavior In the sliding grooves provided at both ends of the board, the vertical section of the U-shaped frame is provided with a horizontal through hole that facilitates the sliding of the behavior board, and the length of the behavior board is greater than the length of the constant board. Simply push the one-sided behavior board 3 and it is unnecessary to destroy all the ceilings, which is more convenient to operate; it can effectively prevent the laser from diffuse reflection and ensure the safety of work staff.

A closed-type fiber laser cutting machine includes a body, the top of the body is continuously provided with a top cover, and the side wall of the top cover is continuously provided with a sliding door. The new layout of this application is simple, start the exhaust fan, the exhaust fan generates wind, and the wind squeezes the exhaust gas generated in the top cover through the air duct and suction pipe. During this process, the filter disc can filter the fine particles in the exhaust gas. Squeezing and contaminating the atmosphere. At the same time, the wind drives the fan blades to roll. The fan blades undergo belts and pulleys to mobilize the filter disc to roll, bringing impurities filtered on the filter disc into the water in the water tank, purifying the filter disc and improving filtration compliance.
