[0002] Compared with traditional cutting methods, laser cutting has the advantages of smaller gaps, high precision, fast cutting speed, smooth incisions and low processing costs. With the further improvement of the requirements for laser processing efficiency, exchangeable table laser cutting machines came into being. The exchangeable table laser cutting machine includes two processing tables. During the processing of the first processing table, the second table can be loaded and unloaded to make full use of the processing waiting time and improve the processing efficiency.

[0003] The laser will generate a large amount of smoke and dust during the cutting process, which affects the laser cutting effect and cutting accuracy. This smoke has a strong pungent smell and seriously endangers the health of the operator. In the prior art, the laser cutting machine is provided with a large enclosure structure, and a dust removal bin is provided at the lower part of the bed. Air ducts are provided on both sides of the dust removal bin. The air ducts are connected to the exhaust equipment through air ducts, and the smoke and dust generated by the cutting are collected through the exhaust equipment.

[0004] Since the two processing tables of the exchangeable table laser cutting machine move at the same time, in order to leave enough layout space for rollers, rails and other components, there is a certain distance between the processing table and the bed in the vertical direction, especially the distance between the upper processing table and the bed is larger, causing smoke and dust to overflow from the space between the processing table and the bed, directly polluting the workshop environment. At the same time, this space is not conducive to the formation of negative pressure inside the large enclosure, affecting the collection effect of smoke and dust. Utility Model Content

[0012] The utility model installs the sealing plate on the bed body, which can prevent the sealing plate from turning over to generate force on the installation plate, and prevent the installation plate from being deformed and the connection from failing.

[0013] Furthermore, dust removal chambers are arranged on both sides of the bed, and a plurality of flap valves are arranged at the openings of the dust removal chambers.

[0014] The utility model can further improve the dust removal effect of the exchangeable double-table laser cutting machine by arranging multiple flap valves.

When the piston rod is extended, the sealing plate 6 rotates to a vertical state for sealing. When the piston rod is retracted, the sealing plate 6 rotates to a position close to the mounting plate 7 to avoid interference with the processing table 8.

[0029] In order to ensure the normal operation of the cylinder 4, a displacement sensor is provided on the cylinder 4. The displacement sensor can detect the extension distance of the piston rod. When the piston rod is not extended into place, the displacement sensor can send an electrical signal to the control system of the laser cutting machine, and then monitor whether the sealing plate 6 is flipped into place every time, so as to detect the failure of the cylinder 4 in time.

The flap valve 2 includes a pneumatic actuator mechanism, which can control the opening and closing of the flap valve 2 respectively. During processing, the flap valve 2 near the crossbeam is opened, and the flap valves 2 at other positions are closed, which can ensure that negative pressure is formed in the dust removal chamber to ensure the dust removal effect. In this specific embodiment, five flap valves 2 are arranged on each side.

[0032] like Figure 1As shown, preferably, an air duct 3 is provided at one end of the bed 5 and located at the lower part of the mounting plate 7, the two ends of the air duct 3 are connected with the two dust removal chambers, and the air duct 3 is connected with the exhaust fan; by arranging the air duct 3 at the lower part of the mounting plate 7, the protective effect of the mounting plate 7 on the air duct 3 can be exerted, thereby extending the service life of the air duct 3.
