Description

Technical Field

[0001] This utility model relates to the field of laser cutting machines, specifically a dust removal structure for laser cutting machines. Background Technology

[0002] The dust collection system of a laser cutting machine is mainly used to collect and process the fumes and waste generated during the cutting process. Its core component is the suction port, which is usually located near the cutting head. It can collect the fumes as soon as they are generated because the fumes produced by laser cutting are very fine and easily disperse in the air. The suction pipe connects the suction port to the dust collection equipment, transporting the collected fumes there.

[0003] The announcement number CN215999097U relates to a zoned dust removal structure for a laser cutting machine, including a base, a placement plate, an electric telescopic rod, and a fixed plate. A first support column is provided between the base and the placement plate, and the placement plate is provided between the placement plate and the fixed plate, and the second support column is provided between them, and the second support column is also provided, and the two are fixedly connected. Currently, with the rapid development of the manufacturing industry, laser cutting technology, due to its high precision and efficiency, is widely used in metal processing and other fields. Cutting generates a large amount of dust, smoke, and slag. Laser cutting machines are generally equipped with dust removal structures, typically with a suction head that moves up and down with the cutting head. When cutting plates of different thicknesses or cutting along complex curves, the cutting head moves, and the suction head follows synchronously, expanding the dust collection range compared to a fixed suction device. However, traditional dust removal structures have significant shortcomings. On the one hand, the spread of pollutants generated during cutting often exceeds the coverage area of ​​the suction head that moves with the cutting head, especially when cutting large plates at high speed. Due to structural limitations, the suction head has a small air outlet, so even if it moves with the cutting head, the effective dust collection range is still limited. The suction head only moves up and down, making it difficult to form a strong and uniform negative pressure field around the cutting area. Dust that is slightly further away cannot be sucked in due to insufficient pressure difference, and some of it remains suspended in the air, which not only affects air quality but may also cause dust to settle on the material surface, affecting the subsequent cutting accuracy and quality.

[0021] Please see Figures 1-5 The present invention provides a technical solution: a dust removal structure for a laser cutting machine, comprising a base 1, a first support plate 2 fixedly connected above the base 1, a first cylinder 3 fixedly connected above the first support plate 2, a first air rod 4 fixedly connected to the output end of the first cylinder 3, a laser cutting machine 5 fixedly connected to the lower end of the first air rod 4, a second cylinder 6 fixedly connected to one side of the first support plate 2, a second air rod 7 fixedly connected to the output end of the second cylinder 6, the second air rod 7 and the first air rod 4 being connected by a vertical sliding connection, a reciprocating mechanism 8 being provided on the inner side of the first support plate 2, and a pushing mechanism 9 being provided below the reciprocating mechanism 8;

[0022] The reciprocating mechanism 8 includes a second support plate 801 vertically slidably connected to the inner side of the first support plate 2. The second support plate 801 has a first guide groove 802 inside, and a first guide rod 803 is provided inside the first guide groove 802. A third support plate 804, fixedly connected to the first air rod 4, is slidably connected laterally below the second support plate 801. A fourth support plate 805 is slidably connected laterally to one side of the second support plate 801. A first guide hole 806 is provided inside the fourth support plate 805. The first guide groove 802 has a wavy shape, and the first guide groove 802 and the first guide rod 803 are fitted with a clearance fit. The first guide hole 806 has a vertical straight shape, and its inner surface fits against the outer surface of the second guide rod 808. The second guide rod 808 has a cuboid shape. This allows the fourth support plate 805 to move horizontally, driving the first guide rod 803 and the second guide rod 808 to move vertically. A second guide rod 808, fixedly connected to the first guide rod 803, is provided inside the first guide hole 806. A first fixed cylinder 809 is fixedly connected to the other end of the second guide rod 808. A second fixed cylinder 810, rotatably connected to the first air rod 4, is provided inside the first fixed cylinder 809. A second guide groove 811 is provided on the outer wall of the second fixed cylinder 810. A third guide rod 812, fixedly connected to the first fixed cylinder 809, is provided inside the second guide groove 811. The second guide groove 811 has a spiral shape, and the second guide groove 811 and the third guide rod 812 are fitted with a clearance fit, allowing the third guide rod 812 to rotate when moving vertically.

[0023] The pushing mechanism 9 includes a fixed plate 901 fixedly connected to the lower end of the second fixed cylinder 810. A second guide hole 902 is provided on the inner side of the fixed plate 901, and a fourth guide rod 903 is provided on the inner side of the second guide hole 902. A third guide groove 904 is provided on the inner side of the third support plate 804, and a fifth guide rod 905 is fixedly connected to the fourth guide rod 903 on the inner side of the third guide groove 904. A connecting block 906 is slidably connected to the lower part of the third support plate 804, and a connecting rod 907 is hinged to the lower part of the connecting block 906. An air intake head 908 is fixedly connected to the lower end of the connecting rod 907 for air intake. The outer side of the head 908 is connected to the air pipe 909. The inner side of the connecting rod 907 is provided with a sliding groove 910. The inner side of the sliding groove 910 is provided with a slider 911 that is hinged to the fourth guide rod 903. The appearance structure of the second guide hole 902 is a horizontal straight line, and the inner side of the second guide hole 902 is in contact with the outer side of the fourth guide rod 903. The appearance structure of the fourth guide rod 903 is a cuboid. The third guide groove 904 consists of multiple arc grooves facing inward and outward, so that when the fourth guide rod 903 rotates, the fifth guide rod 905 is pushed by the edge of the third guide groove 904 to reciprocate.

[0024] During cutting, the second cylinder 6 is activated, driving the second air rod 7 to move laterally. This causes the first cylinder 3 and the first air rod 4 to move laterally, resulting in the laser cutting machine 5 moving laterally alongside the third support plate 804 and the fourth support plate 805. This, in turn, causes the first fixed cylinder 809 and the second fixed cylinder 810 to move laterally, and consequently, the first guide rod 803 and the second guide rod 808 to move laterally. Because the first guide groove 802 has a wavy shape and its fit with the first guide rod 803 is a clearance fit, and the first guide hole 806 has a vertical straight shape with its inner surface fitting against the outer surface of the second guide rod 808 (which is cuboid), the first guide rod 803 and the second guide rod 808 reciprocate up and down, causing the first fixed cylinder 809 to move up and down. This, in turn, causes the third guide rod 812 to move up and down. The guide groove 811 has a spiral shape, and the second guide groove 811 and the third guide rod 812 are fitted with a clearance fit, which allows the second fixed cylinder 810 to rotate, driving the fixed disk 901 and the second guide hole 902 to rotate. The second guide hole 902 has a horizontal straight shape, and its inner surface is in contact with the outer surface of the fourth guide rod 903. The fourth guide rod 903 has a cuboid shape. The third guide groove 904 has multiple arc grooves facing inward and outward, which allows the fifth guide rod 905 to move inside the third guide groove 904 when the fourth guide rod 903 rotates. This causes the fourth guide rod 903 and the fifth guide rod 905 to be pushed by the third guide groove 904 to reciprocate, which causes the fourth guide rod 903 to pull the slider 911, the connecting rod 907, and the suction head 908 to swing, allowing the suction head 908 to rotate and swing, thereby increasing the suction range and improving dust removal efficiency.
