[0022] The technical solution of the present utility model will be described below in conjunction with the drawings and embodiments.

[0023] As Figures 1 to 4 shown, an environment-friendly laser cutting machine of the present utility model includes a frame 1, on which a material roller 11 for assisting in loading and unloading of plates and a processing platform 12 for positioning plates are provided; during loading, the plate is manually pushed onto the processing platform 12 for positioning through the material roller 11; a laser cutting assembly 2, which is driven by a driving device to be movably located above the frame 1 and is used for cutting the plate located on the processing platform 12; a smoke and dust suction device 3, which includes a hose 33, an exhaust fan 34 and a smoke and dust filtering assembly 35. The exhaust fan 34 is fixed on one side of the frame 1. The inlet of the exhaust fan 34 is connected to the first end of the hose 33. The second end of the hose 33 is provided with a suction port 31, and the suction port 31 is correspondingly arranged with the laser cutting head of the laser cutting assembly 2. The outlet of the exhaust fan 34 is connected with an exhaust port 36, and a smoke and dust filtering assembly 35 is arranged between the outlet of the exhaust fan 34 and the exhaust port 36. With such a setting, the smoke and dust suction device 3 replaces the machine cover of the prior art. It has a small volume, occupies little space, is convenient to install, and has a low cost, and the suction effect is better; more specifically, when the laser cutting head of the laser cutting assembly 2 cuts the plate, the exhaust fan 34 is turned on, so that the smoke and dust generated during the cutting process can be quickly sucked in by the suction port 31 in real time, guided through the hose 33 to the outlet of the exhaust fan 34, and then discharged harmless gas from the exhaust port 36 after being filtered by the smoke and dust filtering assembly 35.

[0024] In this embodiment, the suction port 31 is fixedly connected to the laser cutting head of the laser cutting assembly 2. With such a setting, the suction port 31 moves synchronously with the laser cutting head of the laser cutting assembly 2, so that the smoke and dust during the cutting process can be quickly sucked in by the suction port 31 in real time.

[0025] In this embodiment, a mesh grille 311 is installed on the suction port 31. With such a setting, the mesh grille 311 can be used to increase the suction force of the suction port 31, thereby improving the efficiency of sucking smoke and dust.

[0026] In this embodiment, there are multiple air suction openings 31, and the multiple air suction openings 31 are symmetrically arranged on both sides of the laser cutting head of the laser cutting assembly 2. The multiple air suction openings 31 are respectively connected to the second end of the hose 32 through a shunt pressure pipe 32. With this arrangement, the two air suction openings 31 can be used to improve the effect of sucking smoke and dust. At the same time, the smoke and dust sucked by the two air suction openings 31 are gathered in the hose 32 after passing through the shunt pressure pipe 32.

[0027] In this embodiment, a support frame 37 is slidably arranged on the frame 1, and the support frame 37 is fixedly connected to the hose 33. With this arrangement, on the one hand, the support frame 37 supports the hose 33 to prevent the hose 33 from falling onto the processing platform 12 and affecting the cutting effect; on the other hand, it enables the hose 33 to slide relative to the frame 1. Preferably, the support frame 37 is an L-shaped bracket, with one end sliding vertically on the frame 1 and the other end parallel to the upper part of the frame 1.

[0028] In this embodiment, the driving device includes an X-axis moving assembly 21, a Y-axis moving assembly 22, and a Z-axis moving assembly 23. The X-axis moving assembly 21 is used to drive the laser cutting assembly 2 to move left and right in the X-axis direction relative to the processing platform 12, the Y-axis moving assembly 22 is used to drive the laser cutting assembly 2 to move forward and backward in the Y-axis direction relative to the processing platform 12, and the Z-axis moving assembly 23 is used to drive the laser cutting assembly 2 to move up and down in the Z-axis direction relative to the processing platform 12. With this arrangement, it is convenient to drive the laser cutting assembly 2 to displace relative to the processing platform 12 to cut the plate located on the processing platform 12. More specifically, the X-axis moving assembly 21 and the Y-axis moving assembly 22 cooperate to drive the laser cutting assembly 2 to move relative to the processing platform 12 so as to cut the plate located on the processing platform 12 at any position. When moving to the cutting position, the Z-axis moving assembly 23 drives the laser cutting assembly 2 to lift and lower to cut the plate and reset after cutting.

[0029] In this embodiment, a plurality of toothed plates for positioning the plate are provided on the processing platform 12. With this arrangement, the plate can be positioned on the processing platform 12 and will not slide during the cutting process, making the cutting more stable.

[0030] In this embodiment, a plurality of limiting blocks 38 for limiting the wide side and long side of the plate are provided on the frame 1.

[0031] In this embodiment, it further includes an upper controller for controlling the operation of the laser cutting machine.

However, the present utility model is not limited to the above specific embodiments. The above specific embodiments are merely illustrative rather than restrictive. Under the inspiration of the present utility model, those of ordinary skill in the art can also make many forms without departing from the purpose of the present utility model and the scope protected by the claims. All of these fall within the protection scope of the present utility model.
