[0017] Referring to Figs. 1-3 As shown in the figure, a kind of ventilation structure for laser cutting machine bed, including two cross beams 1, two cross beams 1 between both sides are connected with connecting beam 2, several support beams 3 are connected between two connecting beams 2 between two cross beams 1, cross beam 1 and connecting beam 2 and support beam 3 are all hollow, connecting beam 2 and support beam 3 are all through connection with connecting beam 2, one connecting beam 2 side is equipped with suction port 4, air cylinder 5 is installed in support beam 3, air cylinder 5 top is connected with sealing plate 6, support beam 3 top is provided with air inlet matched with sealing plate 6.

[0018] Suction port 4 side is circumscribed with suction equipment, can effectively discharge hot air and waste gas generated inside machine tool. This

[0019] Cross beam 1 bottom is equipped with several support feet 7, increase the stability of machine tool. Support foot can effectively bear the gravity and vibration when machine tool runs, prevent machine tool from tilting or unstable during operation.

[0020] Support beam 3 top is equipped with protective screen cover 8 above sealing plate 6, can effectively prevent sundries from entering the ventilation system of machine tool, to guarantee the normal operation of ventilation system.

[0021] Cross beam 1 is equipped with several reinforcing ribs 9, can enhance the structural strength of cross beam 1, improve the stability and carrying capacity of overall frame.

[0022] Working principle: the ventilation system of the laser cutting machine tool is composed of two cross beams 1, a plurality of connecting beams 2 and a plurality of supporting beams 3. The cross beam 1 and the connecting beam 2 are hollow structures, and the ventilation channel is formed by penetrating connection. The supporting beam 3 is connected between the cross beam 1 and the connecting beam 2, and the supporting beam 3 is also hollow and connected with the connecting beam 2 to form a through ventilation channel system. During the ventilation process, air enters through the air inlet at the top of the supporting beam 3. The arrangement of the air inlet ensures that air can flow into the channel in the supporting beam 3, and then the air flows through the channel between the supporting beam 3 and the connecting beam 2, and finally flows to the air outlet 4. The air outlet 4 is connected with the air extraction equipment to extract the hot air and waste gas generated inside the machine tool, so as to maintain the stability of the temperature inside the machine tool. During the laser cutting process, when the laser cutting head works at a certain position, the air cylinder 5 is started to push the sealing plate 6 located in the supporting beam 3 to open, so as to allow more air to flow into the ventilation system of the position. The sealing plate 6 of other positions remains closed to ensure that the air flow is concentrated in the cutting position and the heat dissipation effect of the area is enhanced. The air cylinder 5 controls the opening and closing of the sealing plate 6, so as to accurately adjust the ventilation volume and air extraction effect of each area. When the power of the air extraction equipment is fixed, the number and size of the air inlets directly affect the air extraction effect. According to the ventilation principle, the fewer or smaller the air inlets are, the greater the resistance of air inflow is, thereby enhancing the negative pressure effect of the air outlet and improving the exhaust efficiency. Therefore, by controlling the size and number of the air inlets, the performance of the air extraction equipment can be effectively improved.
