Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting equipment, and particularly relates to a ground-rail type bevel laser cutting machine. Background Art

[0002] Existing ground-rail type laser cutting machines (such as the Chinese patent with the publication number CN 211028585U) include two rows of parallel ground rails. The lower part of the ground rails is provided with floor feet. Along the length direction of the ground rails, a rack and a guide rail are arranged on the upper part of the ground rails. The rack and the guide rail are parallel. A cross beam that can move along the length direction of the ground rails is movably arranged on the rack and the guide rail. A laser cutting assembly that can reciprocate along the cross beam is movably arranged on the cross beam. A workbench is arranged between the two rows of ground rails, and support columns are arranged at the lower part of the workbench.

[0003] When the cross beam drives the laser cutting assembly to cut a plate located on the workbench, the high-energy laser emitted by the laser cutting assembly will generate a large amount of heat, and a large amount of dust and fine chips will be generated during cutting. For example, the Chinese patent with the publication number CN213163620U discloses a smoke exhaust system for a ground-rail type laser cutting machine, which includes a smoke exhaust area arranged below the cutting machine body. The smoke exhaust area is divided into multiple independent smoke exhaust area units. Each smoke exhaust area unit is provided with an air extraction port. The outside of the air extraction port is connected to a smoke exhaust mechanism. An opening and closing control valve is arranged between each air extraction port and the smoke exhaust mechanism. By arranging multiple partitions on the machine body to discharge the cutting dust at different positions, and by arranging a separate air extraction port and an exhaust branch pipe for each smoke exhaust area unit, and then controlling through the opening and closing control valve, each partition unit can exhaust smoke separately, which is targeted, can improve the smoke exhaust efficiency, and ensure the smoke exhaust effect. However, the above smoke exhaust system has a large structure and can only extract the dust at the smoke exhaust area unit, and cannot extract dust from the source of the laser cutting assembly.

[0051] The present invention provides a floor - rail type bevel laser cutting machine. To make the purpose, technical solutions and effects of the present invention clearer and more definite, the following further elaborates on the present invention with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the protection scope of the present invention.

[0052] In this embodiment, the X - axis direction is the same as the left - right direction, the Y - axis direction is the same as the front - back direction, and the Z - axis direction is the same as the up - down direction.

[0053] Please refer to Figures 1 - 7, the present invention provides a ground-rail type bevel laser cutting machine, which includes a hollow bed body A, a cutting platform D arranged in the middle of the bed body A, a cross beam A3 slidably arranged on the bed body A, and a laser bevel cutting structure C slidably arranged on the cross beam A3; on any inner side wall of the bed body A, a follow-up air extraction structure B is arranged, and the follow-up air extraction structure B includes an air extraction pipeline B1, an air extraction belt B2 arranged on the air extraction pipeline B1, an air extraction box B3 arranged on the air extraction belt B2, and a jacking assembly B4 arranged in the air extraction box B3; the air extraction pipeline B1 extends along the length direction of the bed body A, and an opening is provided on its upper part, the air extraction belt B2 covers the opening, and both ends of the air extraction belt B2 are connected to the air extraction pipeline B1; the air extraction box B3 is slidably arranged on the air extraction pipeline B1, and an air suction port B31 is arranged on the side wall of the air extraction box B3 facing the laser bevel cutting structure C, and an opening is provided at its lower part, and the jacking assembly B4 is used to jack up the air extraction belt B2 to communicate the air extraction box B3 with the air extraction pipeline B1; a fixing frame B5 is arranged on the air extraction box B3, and the fixing frame is connected to the cross beam A3; one end of the air extraction pipeline B1 is a closed end, and the other end is connected to an air extraction port B32, and the air extraction port B32 is used to connect to an air extraction device; the air extraction device is used to make the air extraction pipeline B1 and the air extraction box B3 form a negative pressure.

[0054] The hollow bed body A and the cutting platform D are of a split structure, so that the heat transferred from the laser bevel cutting structure C to the cutting platform D cannot be transferred to the bed body A, which is beneficial to extending the service life of the bed body A; the cutting platform D is used to carry the plate to be cut. When the cross beam A3 reciprocates on the bed body A, the fixing frame B5 drives the air extraction box B3 to reciprocate in the length direction of the bed body A. During the movement of the air extraction box B3, the jacking assembly B4 jacks up the air extraction belt B2 located in the air extraction box B3 to communicate the air extraction box B3 with the air extraction pipeline B1, so that the dust generated when the laser bevel cutting structure C cuts the plate enters the inside of the air extraction box B3 from the air suction port B31 on the air extraction box B3, then enters the air extraction pipeline B1, and finally gathers in the air extraction device; and the air extraction belt B2 located outside the air extraction box B3 tightly adheres to the air extraction pipeline B1 under the action of negative pressure.

[0055] The ground-rail type bevel laser cutting machine is provided with a bed body A for carrying the cross beam A3, a cutting platform D for carrying the plate to be cut, a laser bevel cutting structure C for cutting the plate, an air extraction pipeline B1 for forming a negative pressure, an air extraction belt B2 for keeping the air extraction pipeline B1 in a sealed state, an air suction port B31 and an air extraction box B3 for sucking the dust generated by the laser bevel cutting structure C, and a jacking assembly B4 for communicating the air extraction box B3 with the air extraction pipeline B1, so that the dust generated when the laser bevel cutting structure C cuts the plate can be timely sucked away by the air extraction device.

[0056] Please refer to Figure 7 , further, in this embodiment, the exhaust box B3 is a cuboid, and the lifting components B4 are provided in four numbers, and the four lifting components B4 are respectively arranged at the four corner positions of the exhaust box B3; each lifting component B4 includes a belt pulley B41 and a belt pulley shaft B42; the belt pulley shaft B42 penetrates through the left and right side walls of the exhaust box B3, and the outer peripheral wall of the belt pulley shaft B42 is rotatably connected with the belt pulley B41; the four belt pulleys B41 are all in contact with the exhaust belt B2, the rotation directions of the two belt pulleys B41 located above are the same, and the rotation directions of the two belt pulleys B41 located below are opposite to the rotation directions of the two belt pulleys B41 located above. Driven by the cross beam A3, the exhaust box B3 moves. Since both ends of the exhaust belt B2 are fixed on the exhaust duct B1, the four belt pulleys B41 are rotated under the action of the exhaust belt B2. The lifting component B4 is used on the one hand to tighten the exhaust belt B2 and play a role in fixing the position of the exhaust belt B2 in the exhaust box B3, and on the other hand to reduce the friction with the exhaust belt B2. Taking the backward movement of the exhaust box B3 as an example in this embodiment, the two belt pulleys B41 located above rotate clockwise, while the two belt pulleys B41 located below rotate counterclockwise.

[0057] Please refer to Figure 7 , further, the lifting component B4 further includes a belt limiting piece B43, and the belt limiting piece B43 is arranged at both ends of the corresponding belt pulley B41. The belt limiting piece B43 is arranged to limit the movement of the exhaust belt B2 to prevent the exhaust belt B2 from contacting the inside of the exhaust box B3 when the belt pulley B41 rotates at a high speed, affecting the normal operation of the follow-up exhaust structure B.

[0058] Please refer to Figure 3 and Figure 4 , further, auxiliary wheel mounting seats B33 are arranged on the front side wall and the rear side wall of the exhaust box B3, and auxiliary rollers B34 are arranged on the auxiliary wheel mounting seats B33, and the auxiliary rollers B34 are in contact with the upper surface of the exhaust belt B2. Through the above setting, it is used to prevent the problem that the exhaust belt B2 outside the exhaust box B3 scratches the lower part of the exhaust box B3 and increases the friction.

During actual use, the position of the auxiliary wheel mounting seat B33 on the air extraction box B3 can be finely adjusted up and down to adjust the tightness of the air extraction belt B2. Specifically, when the auxiliary wheel mounting seat B33 moves downward, the pressure on the air extraction belt B2 in the air extraction box B3 increases, thereby tightening the air extraction belt B2; when the auxiliary wheel mounting seat B33 moves upward, the pressure on the air extraction belt B2 in the air extraction box B3 decreases, thereby reducing the tension of the air extraction belt B2.

[0060] Please refer to Figure 3 , Further, brush bristles B35 are respectively provided on the lower parts of the left and right side walls of the air extraction box B3, and the brush bristles B35 are in contact with the side walls of the corresponding air extraction pipes B1.

Similarly, the other end of the air extraction belt B2 is fixed to the other end of the air extraction pipe B1 to complete the installation; when replacing the air extraction belt B2 or repairing the follow-up air extraction structure B, the air extraction belt B2 can be disassembled.

The exhaust duct B1 can be spliced into different lengths according to the requirements of the customer for the length of the cut plate, with strong applicability and high practicability. The disassembled exhaust duct B1 is also conducive to container loading, improving the utilization rate of the container and reducing the transportation cost. The exhaust support base B14 is provided for supporting the multiple exhaust ducts B1; the lower surface of the height-adjustable foot cup B15 contacts the ground of the workshop, and the height-adjustable foot cup B15 can finely adjust the levelness of the exhaust duct B1 according to the flatness of the workshop floor.

[0064] Please refer to Figure 8 , Further, each exhaust duct B1 is provided with a second waist-shaped hole B111 extending along its width direction, the exhaust support base B14 is provided with a second mounting hole corresponding to the second waist-shaped hole B111, and a second bolt (not shown in the figure) is arranged on the second waist-shaped hole B111 and the second mounting hole. By finely adjusting the relative positions of the exhaust support base B14 and the exhaust duct B1, the exhaust duct B1 is moved towards the laser bevel cutting structure C or away from the laser bevel cutting structure C, so as to improve the dust removal effect of the follow-up exhaust structure B.
