DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1-Figure 4 As shown, in this embodiment, a metal laser cutting machine includes an operating table 1, a transmission groove 6 is provided inside the operating table 1, a driven roller 7 and an active roller 8 are rotatably connected between the inner walls of the transmission groove 6, a conveyor belt 5 is provided between the outer sides of the driven roller 7 and the active roller 8, two vertical plates 2 are fixedly connected to the top of the operating table 1, a horizontal plate 3 is fixedly connected between the two vertical plates 2, a chute 4 is provided inside the horizontal plate 3, a displacement block 13 is slidably connected to the outer side of the horizontal plate 3, a displacement component is provided inside the chute 4, the displacement component is used to drive the displacement block 13 to move, and the bottom of the displacement block 13 is fixedly connected There is a connecting plate 21, and the two sides of the connecting plate 21 are respectively fixedly connected with a first L-shaped mounting plate 23 and a second L-shaped mounting plate 24, a laser cutter 10 is fixedly installed on the outer side of the first L-shaped mounting plate 23, a cutting head 11 is arranged at the bottom of the laser cutter 10, and a dust collection assembly is arranged on the outer side of the second L-shaped mounting plate 24, a power motor 18 is fixedly installed on one side of the operating table 1, the output end of the power motor 18 extends to the inside of the transmission groove 6 and is fixedly connected to the active roller 8, a buffer plate 9 is fixedly connected between the inner walls of the transmission groove 6, and the top of the buffer plate 9 contacts the inner side of the conveyor belt 5.

[0022] When performing metal laser cutting, the metal piece to be cut is placed above the conveyor belt 5, and the power motor 18 is used to drive the active roller 8 to rotate, so that the conveyor belt 5 moves inside the transmission trough 6 and drives the driven roller 7 to rotate, and further the metal piece is moved above the operating table 1 through the conveyor belt 5. When the metal piece moves below the cutting head 11, the laser cutter 10 is started by the controller, so that the cutting head 11 cuts the metal piece. At this time, the displacement component is used to cooperate with the laser cutter 10, so that the cutting head 11 can cut the metal piece in multiple places, which greatly improves the efficiency of the cutting work. At the same time, the dust and odor generated after laser cutting are absorbed by the dust suction component, thereby improving the cutting efficiency while reducing the impact of dust and odor on the working environment, and further reducing the risk of damage to the respiratory system, eyes and skin of the staff.

[0023] like Figure 1-Figure 4 As shown, the dust collection assembly includes a fan 15 and a dust collecting box 14, the fan 15 is fixedly mounted on the bottom of the second L-shaped mounting plate 24, the dust collecting box 14 is fixedly connected to the top of the displacement block 13, the input end of the fan 15 is fixedly connected to the second connecting pipe 20, the other end of the second connecting pipe 20 is fixedly connected to the dust collection head 19, the output end of the fan 15 is fixedly connected to the first connecting pipe 16, the other end of the first connecting pipe 16 is fixedly connected to the dust collecting box 14, the top of the dust collecting box 14 is fixedly connected to the exhaust pipe 25, the interior of the exhaust pipe 25 is provided with an air purification filter element, and the air purification filter element is an activated carbon filter element.

[0024] The fan 15 is started by the controller, and the dust and odor generated in the cutting area are absorbed by the dust suction head 19. The absorbed dust and odor are then transferred to the dust collecting box 14 through the first connecting pipe 16 and the second connecting pipe 20. The inhaled dust is collected by the dust collecting box 14, and the gas passing through the exhaust pipe 25 is filtered by the activated carbon filter element, thereby further reducing the impact of dust and odor on the working environment.

[0025] like Figure 1-Figure 4 As shown, the displacement assembly includes a threaded rod 12, which is rotatably connected between the inner walls of the slide groove 4, and the outer side of the threaded rod 12 is threadedly connected to the displacement block 13. A servo motor 17 is fixedly installed on one side of the vertical plate 2, and the output end of the servo motor 17 extends to the interior of the slide groove 4 and is fixedly connected to the threaded rod 12.

[0026] The threaded rod 12 is driven to rotate by the servo motor 17, and the rotation of the threaded rod 12 further drives the displacement block 13 to slide on the outside of the cross plate 3, so that the staff can drive the laser cutter 10 to cut different positions of the metal plate by adjusting the movement of the displacement block 13, thereby further improving the cutting efficiency.

[0027] like Figure 1-Figure 4 As shown, buffer pads 22 are fixedly connected to both sides of the connecting plate 21 .

[0028] By fixing the connection buffer pads 22 on both sides of the connection plate 21, the buffer pads 22 can be used to reduce the contact between the connection plate 21 and the vertical plate 2 when the displacement block 13 moves, thereby avoiding collision and affecting the service life of the laser cutter 10.

[0029] The utility model provides a metal laser cutting machine, and the specific working principle is as follows: when performing metal laser cutting, the metal piece to be cut is placed above the conveyor belt 5, and the power motor 18 is used to drive the active roller 8 to rotate, so that the conveyor belt 5 moves inside the transmission groove 6 and drives the driven roller 7 to rotate, and further the metal piece is moved above the operating table 1 through the conveyor belt 5. When the metal piece moves to the bottom of the cutting head 11, the laser cutter 10 is started by the controller, so that the cutting head 11 cuts the metal piece. At this time, the servo motor 17 is used to drive the threaded rod 12 to rotate, and the displacement block 13 is further driven by the rotation of the threaded rod 12. Sliding on the outside of the horizontal plate 3, the laser cutter 10 moves with the displacement block 13, so that the cutting head 11 can cut the metal part in multiple places. While the cutting operation is being performed, the fan 15 is started by the controller, and the dust and odor generated in the cutting area are absorbed by the dust suction head 19. Then, the absorbed dust and odor are transmitted to the dust collection box 14 through the first connecting pipe 16 and the second connecting pipe 20. The inhaled dust is collected by the dust collection box 14, and the gas passing through the exhaust pipe 25 is filtered by the activated carbon filter element. After the cutting is completed, the cut metal part is sent away from the metal laser cutting machine through the conveyor belt 5.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
