Beneficial Effects

[0007] 1. The present invention assists the high-temperature metal vapor generated during the laser cutting process to move downward by using the negative pressure generated inside the main support platform, so that the high-temperature metal vapor generated during the metal cutting process is less likely to accumulate at the bottom of the metal plate to cause slag, thereby improving the cutting effect.

The main support platform 1 is provided with a cleaning mask block 26 on the upper part, and a waste residue recovery pipe 28 is provided on the top of the cleaning mask block 26. The end of the waste residue recovery pipe 28 is connected to an exhaust fan. The cleaning mask block 26 has a waste residue recovery hole 27 inside, and the cleaning mask block 26 has gear mounting plates 18 on both sides, wherein the gear mounting plate 18 on the side away from the lower recovery cover 13 has a limiting wheel mounting platform 62 at the bottom, and the gear mounting plate 18 The outer side is provided with a cleaning motor slot 36, and a cleaning drive motor 37 is inserted into the cleaning motor slot 36 and fixed therein. A transmission shaft of the cleaning drive motor 37 passes through the gear mounting plate 18 and is fixedly connected to a swing drive gear 49. A travel gear mounting shaft 46 is provided on one side of the gear mounting plate 18. The travel gear mounting shaft 46 is rotatably connected to the travel drive gear 39. The bottom of the travel drive gear 39 is meshed with the travel rack 38, and the side of the travel drive gear 39 is meshed with the swing drive gear 49. A main support wheel connecting shaft 47 is provided on the side of the travel gear mounting shaft 46. The main support wheel connecting shaft 47 is rotatably connected to the main support wheel 48. The supporting wheel 48 is pressed against the upper surface of the main supporting platform 1, and a secondary supporting wheel mounting platform 54 is provided on the other side of the gear mounting plate 18. A secondary supporting wheel mounting platform 54 has a secondary supporting wheel connecting shaft 52 on the side thereof, and the secondary supporting wheel connecting shaft 52 is rotatably connected to the secondary supporting wheel 53. The secondary supporting wheel 53 is pressed against the upper surface of the main supporting platform 1, and a limiting wheel mounting platform 62 has a limiting wheel mounting groove 63 inside thereof, and the limiting wheel mounting groove 63 is rotatably connected to the limiting wheel 64. The limiting wheel 64 is pressed against the lower side of the traveling rack 38 at the corresponding position, and a waste residue cleaning knife 25 is provided inside the cleaning mask block 26. A laser cutting sword grating 14 is provided on the top of the main supporting platform 1. An exhaust gas passage hole 43 is arranged between adjacent laser cutting sword grids 14, the laser cutting sword grid 14 is adapted to the waste slag cleaning knife 25, the laser cutting sword grid 14 is connected to the waste slag cleaning knife 25, the waste slag cleaning knife 25 slides on the outside of the laser cutting sword grid 14, the waste slag cleaning knife 25 has swing column connecting blocks 44 on both sides, the swing column connecting blocks 44 have swing column connecting grooves 45 inside, the swing drive gear 49 has a swing drive column 51 on the side, the swing drive column 51 is adapted to the swing column connecting groove 45, the swing drive column 51 is connected to the swing column connecting groove 45, and the swing drive column 51 slides inside the swing column connecting groove 45.

[0028] Furthermore, the high-temperature metal vapor generated during the laser cutting process is blown into the main support platform 1 through the exhaust gas hole 43, and the vacuum pump connected to the lower exhaust gas recovery pipe 12 is started to generate negative pressure inside the main support platform 1, so that the high-temperature metal vapor blown into the main support platform 1 passes through the waste slag collection net 24 and the cooling net 23 and enters the lower exhaust gas recovery pipe 12. At the same time, the coolant is injected into the cooling net 23 from the coolant carrying pipe 17 on one side and flows out from the coolant carrying pipe 17 on the other side, so that the cooling net 23 cools the waste slag collection net 24, so that the high-temperature metal vapor directly condenses on the surface of the waste slag collection net 24 when passing through the waste slag collection net 24, and the remaining waste gas is subsequently recovered by the lower exhaust gas recovery pipe 12.

[0029] Furthermore, after the laser cutting is completed, the cleaning drive motor 37 is started, and the cleaning drive motor 37 drives the swing drive gear 49 to rotate, and the swing drive gear 49 drives the traveling drive gear 39 to rotate, so that the waste slag cleaning mechanism 3 moves in a straight line on the traveling rack 38. While moving, the swing drive column 51 of the swing drive gear 49 slides inside the swing column connecting groove 45 of the waste slag cleaning knife 25, so that during the advancement of the laser cutting mechanism 4, the waste slag cleaning knife 25 continues to slide left and right at high speed on the surface of the laser cutting sword fence 14, thereby completing the cleaning of the waste slag on the surface of the laser cutting sword fence 14. At the same time, the vacuum pump connected to the positioning drive gear 66 is started to generate negative pressure inside the cleaning mask block 26, and the waste slag is recovered through the waste slag recovery hole 27.

[0030] It should be noted that the negative pressure generated inside the main support platform 1 assists the high-temperature metal vapor generated during the laser cutting process to move downward, making it less likely for the high-temperature metal vapor generated during the metal cutting process to accumulate at the bottom of the metal plate to cause slag, thereby improving the cutting effect.

[0031] It should also be noted that the coolant flowing through the cooling net 23 cools the waste slag collection net 24, so that the high-temperature metal vapor passing through the waste slag collection net 24 is cooled and condensed on the waste slag collection net 24, which is convenient for the subsequent centralized recovery of waste slag. At the same time, it also avoids excessive accumulation of waste slag on the laser cutting sword grating 14, which is convenient for the subsequent cleaning of the laser cutting sword grating 14. The cutting section is neat and has good flatness, which prevents bumps and concavities below the cutting surface.

[0032] It should also be noted that during the forward movement of the laser cutting mechanism 4, the waste slag cleaning knife 25 inside the laser cutting mechanism 4 continues to swing left and right. Through the left and right swing of the waste slag cleaning knife 25, the waste slag cleaning knife 25 can clean the same position of the laser cutting sword fence 14 multiple times during the forward movement of the laser cutting mechanism 4, thereby improving the cleaning effect of this device.

[0033] It should also be noted that the cleaning mask block 26 itself is an inverted U-shaped design, so that the cleaning mask block 26 always covers the outside of the waste cleaning knife 25 during the cleaning process, thereby avoiding secondary pollution caused by waste overflow during the cleaning process. At the same time, the waste residue cleaned will also be recovered through the waste recovery hole 27, making the cleaning process more efficient and tidy.
