The blocking curtains on both sides of the smoke suction pipe will stretch in and out of the opening along with the movement of the smoke suction pipe, no matter which side the smoke suction pipe moves to, the blocking curtains on both sides will block the first opening 105, ensuring that the smoke will not float out of the first opening 105, avoiding damage to the surrounding environment, making it difficult to clean and causing lung disease when inhaled by the staff, and realizing more comprehensive and efficient treatment of the smoke generated in laser cutting.

[0027] Specifically, the cutting table body is a box structure, further comprising a square bottom plate, four side plates vertically arranged on the four sides of the bottom plate, and a cavity between the bottom plate and the four side plates, which is a cavity for the smoking pipe to enter and suck smoke. The second opening is arranged at the top of the cutting table body, and the bearing part 2 is arranged at the top of the cutting table body. The opening is arranged on one of the side plates. The curtain can be an elastic curtain made of high-temperature-resistant elastic material, or a foldable curtain. When the curtain is an elastic curtain, the smoking pipe will be continuously compressed and rebounded when moving back and forth at the opening, and will follow the smoking pipe to make a contraction movement at the opening, so as to keep the first opening 105 closed except for the smoking pipe, thereby avoiding smoke from flowing out of the opening. When the curtain is a foldable curtain, a positioning frame can be provided outside the smoking pipe, and two curtains are connected to the two sides of the positioning frame. The relative movement of the smoking pipe and the cutting table body causes the positioning frame to move with the smoking pipe, and the positioning frame drives the two foldable curtains to stretch and contract in the opening, so that the opening is always kept sealed, thereby avoiding smoke from flowing out of the opening. The cutting table and the smoking pipe can move relative to each other, that is, the cutting table can be arranged on the driving device to change the position of the smoking pipe in the cavity by moving the cutting table, or the smoking pipe can be arranged on the driving device to change the position of the smoking pipe in the cavity by moving the smoking pipe.
