[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. This laser cutting equipment for aluminum alloy ladder production clamps the workpiece onto an electric rotating clamp and lowers the main body of the laser cutting machine. The main body of the laser cutting machine can then be used to cut the workpiece. At the same time, the workpiece rotates together with the clamping plate on the electric rotating clamp, facilitating the completion of the cutting operation. Air is blown through the air hose, and the air nozzle blows air towards the cutting point of the workpiece to blow away the molten material at the cutting point, allowing the cutting point to be smoothly broken.

[0018] 2. This laser cutting equipment for aluminum alloy ladder production can achieve automatic cleaning. During the air blowing process at the workpiece cutting area, molten liquid will splash onto the lens inside the laser head. After the cutting operation is completed, the main body of the laser cutting machine can be raised. When the rangefinder detects that the distance between the main body of the laser cutting machine and the workpiece reaches a certain value, it triggers the extension of the second electric telescopic column. The first piston, moving plate and the first extrusion frame move down as a whole. The toothed plate moves down and drives the third air blowing pipe and air blowing hose to rotate 180 degrees as a whole. The air blowing hose is aligned with the lens inside the laser head. The rotating frame, opening and closing parts and dust collection screen rotate 180 degrees as a whole. The dust collection screen is located on the right side of the opening and closing parts. At the same time, the first rotating rod and the second rotating rod rotate and close. The two clamping rods clamp the air blowing hose into a duckbill shape. The air blowing hose blows air towards the lens, which facilitates the automatic blowing away of dust and splashed liquid.

[0019] 3. The laser cutting equipment for aluminum alloy ladder production can be easily disassembled and replaced. When the dust and splashed liquid on the inner lens of the laser head are removed by the air blowing hose, the dust and splashed liquid will adhere to the dust collection screen. After removing the sleeve, the dust collection screen can be removed for cleaning or replacement. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 11 The present invention provides a technical solution: a laser cutting equipment for aluminum alloy ladder production, including a base 1, a support plate 2 and a bracket 4 fixed on the upper end surface of the base 1, an electric rotating clamping component 3 fixed on the support plate 2, a first electric telescopic column 5 fixed on the inner top of the bracket 4, a laser cutting machine body 6 fixed on the bottom of the first electric telescopic column 5, a rangefinder 7 and a laser head 8 fixed on the bottom of the laser cutting machine body 6, an air nozzle 9 threadedly connected to the bottom of the laser head 8, a first through hole 10 opened on one side of the laser head 8, and a dust collection mechanism 11 passing through the first through hole 10.

[0034] An air blowing mechanism 18 is fixed to one side of the laser cutting machine body 6. The air blowing mechanism 18 includes an air cooling channel 1801. The air cooling channel 1801 is fixed to one side of the laser cutting machine body 6 by a third bolt 1802. A first air blowing pipe 1805 is fixed to the bottom of the air cooling channel 1801. The end of the first air blowing pipe 1805 is connected to a second air blowing pipe 1806 by a pipe clamp. The end of the second air blowing pipe 1806 passes through the other side of the laser head 8 and is rotatably connected to a third air blowing pipe 1807. An air blowing hose 1809 is fixed to the end of the third air blowing pipe 1807.

[0035] In this embodiment, as Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 9 As shown, the dust collection mechanism 11 includes a sleeve 1101, which passes through the first through hole 10. The sleeve 1101 is fixed to the laser head 8 by the first bolt 1102. Two second through holes 1103 are opened on one side of the sleeve 1101, and a first spring 1104 is fixed in one of the second through holes 1103. A first movable block 1105 is fixed to one end of the first spring 1104. The sleeve 1101 can be fixed to the laser head 8 under the action of the first bolt 1102, which is convenient for disassembly and assembly. When the first movable block 1105 is squeezed and moves to the right, it can drive the corresponding component to move to the right. The first spring 1104 can assist the first movable block 1105 to reset.

[0036] In this embodiment, as Figure 3 , Figure 4 , Figure 6 and Figure 9As shown, a movable rod 1107 extends through both the top and bottom of the sleeve 1101, and a second movable block 1106 is fixed to the inner end of the movable rod 1107. One of the second movable blocks 1106 is wedge-shaped and fitted to the top of the first movable block 1105, and the other second movable block 1106 is wedge-shaped and fitted to the bottom of the first movable block 1105. The movable rod 1107 at the bottom of the sleeve 1101 and the corresponding second movable block 1106 provide a supporting and blocking effect on the first movable block 1105. When the movable rod 1107 at the top of the sleeve 1101 moves downward, it can drive the corresponding first movable block 1105 to move downward, which facilitates squeezing the second movable block 1106 to move to the right.

[0037] In this embodiment, as Figure 3 , Figure 4 , Figure 6 and Figure 9 As shown, a movable frame 1108 is fixed to one side of the first movable block 1105. Slide grooves 1109 are provided in the top and bottom of the sleeve 1101. The movable frame 1108 is slidably connected in the two slide grooves 1109. A rack 1110 is symmetrically fixed on both sides of the front end face of the movable frame 1108. When the first movable block 1105 is squeezed and moves to the right, the movable frame 1108 moves to the right accordingly. The two slide grooves 1109 limit the movement of the movable frame 1108.

[0038] In this embodiment, as Figure 3 , Figure 4 , Figure 6 and Figure 9 As shown, gears 1111 are rotatably connected to both the inner top and bottom of sleeve 1101, and gears 1111 are meshed with the front side of rack 1110. A rotating frame 1112 is fixed between the two gears 1111, and opening and closing elements 1113 are symmetrically rotatably connected to the two inner walls of the rotating frame 1112. The opening and closing elements 1113 are connected to the rotating frame 1112 through torsion springs, and a dust collection screen 1114 is fixed to one side of the rotating frame 1112 by a second bolt 1115. Because gears 1111 and rack 1110... When the moving frame 1108 and the rack 1110 move left and right, they can drive the gear 1111 to rotate, thereby driving the rotating frame 1112 to rotate, which facilitates the adjustment of the position of the dust collection screen 1114. When the dust collection screen 1114 is on the left side of the opening and closing part 1113, the opening and closing part 1113 is blocked by the dust collection screen 1114 and cannot be rotated open. When the dust collection screen 1114 is on the right side of the opening and closing part 1113, the opening and closing part 1113 can be automatically rotated open under the action of airflow, and the gas can be discharged through the two second through holes 1103.

[0039] In this embodiment, as Figure 6 , Figure 9 and Figure 11As shown, a second electric telescopic column 12 and a first hydraulic cylinder 13 are fixed inside the laser head 8. A first piston 14 is fixed to the bottom of the second electric telescopic column 12. The first piston 14 is slidably connected inside the first hydraulic cylinder 13 and passes through the bottom of the first hydraulic cylinder 13 and is connected to the moving plate 15. A first extrusion frame 16 is fixed on the moving plate 15 and is slidably connected inside the laser head 8. The first piston 14 can move up and down under the telescopic action of the second electric telescopic column 12 to facilitate the pumping of hydraulic oil in the first hydraulic cylinder 13. At the same time, the up and down movement of the first piston 14 can drive the moving plate 15 and the first extrusion frame 16 to move up and down as a whole. When the first extrusion frame 16 moves down, it can extrude the movable rod 1107 at the top of the sleeve 1101.

[0040] In this embodiment, as Figure 1 , Figure 3 and Figure 5 As shown, an electric air intake valve 1803 is fixed on one side of the air-cooling channel 1801, and guide plates 1804 are fixed at equal intervals on the inner wall of the air-cooling channel 1801. When the electric air intake valve 1803 is opened, air can be introduced into the air-cooling channel 1801, and the guide plates 1804 can guide the air onto the laser cutting machine body 6, which facilitates the cooling and heat dissipation of the laser cutting machine body 6.

[0041] In this embodiment, as Figure 3 , Figure 5 , Figure 6 , Figure 8 and Figure 10 As shown, a gear ring 1808 is fixed to the outer side of the third air blowing pipe 1807, and shafts 1810 are symmetrically fixed to both sides of the third air blowing pipe 1807. The outer ends of the shafts 1810 are rotatably connected to a first rotating rod 1811 and a second rotating rod 1812. The first rotating rod 1811 is connected to the outer side of the second rotating rod 1812 through a second spring 1813. Clamping rods 1814 are fixed between the two first rotating rods 1811 and between the two second rotating rods 1812. The second spring 1813 provides support for the first rotating rods 1811 and the second rotating rod 1812. When the first rotating rod 1811 and the second rotating rod 1812 are squeezed, the first rotating rod 1811 and the second rotating rod 1812 will rotate and close together, and the two clamping rods 1814 will approach each other and clamp the air hose 1809 into a duckbill shape, which facilitates increasing the blowing intensity of the air hose 1809. When the squeezing of the first rotating rod 1811 and the second rotating rod 1812 is released, the first rotating rod 1811 and the second rotating rod 1812 will automatically rotate and open under the action of the second spring 1813, and the two clamping rods 1814 will release the air hose 1809, and the air hose 1809 will return to a round tube shape.

[0042] In this embodiment, as Figure 10As shown, second oil cylinders 1815 are symmetrically fixed on both sides of the third air blowing pipe 1807, and a second piston 1816 is slidably connected inside the second oil cylinder 1815. The second piston 1816 passes through one end of the second oil cylinder 1815 and is connected to the second extrusion frame 1817. The second extrusion frame 1817 is sleeved on the outside of the first rotating rod 1811 and the second rotating rod 1812. When oil is pressed into the second oil cylinder 1815, the second piston 1816 slides to the right, thereby driving the second extrusion frame 1817 to move to the right, so as to extrude the first rotating rod 1811 and the second rotating rod 1812. When oil is drawn out of the second oil cylinder 1815, the second piston 1816 and the second extrusion frame 1817 move to the left, so as to release the extrusion on the first rotating rod 1811 and the second rotating rod 1812.

[0043] In this embodiment, as Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, a third hydraulic cylinder 1818 is fixed inside the laser head 8, and a third piston 1819 is slidably connected inside the third hydraulic cylinder 1818. A toothed plate 1820 is fixed to the bottom of the third piston 1819, and the toothed plate 1820 passes through the bottom of the third hydraulic cylinder 1818 and is engaged with the rear side of the toothed ring 1808. Two second hydraulic cylinders 1815 are connected to the third hydraulic cylinder 1818 through a second connecting pipe 1821, and the third hydraulic cylinder 1818 is connected to the first hydraulic cylinder 13 through a first connecting pipe 17. The first connecting pipe 17 serves to connect the first hydraulic cylinder 13 and the third hydraulic cylinder 1818. The function of 818 is to connect the third oil cylinder 1818 and the two second oil cylinders 1815. When the first piston 14 moves downward, the third piston 1819 can move downward under the action of oil pressure, and the toothed plate 1820 moves downward, thereby driving the third air blowing pipe 1807 and the air blowing hose 1809 to rotate 180 degrees as a whole, so as to facilitate the adjustment of the direction of the air blowing hose 1809. At the same time, when the third piston 1819 moves downward, the two second pistons 1816 move to the right under the action of oil pressure, and the two second extrusion frames 1817 move to the right accordingly.

[0044] The method of use and advantages of this invention: The laser cutting equipment for producing aluminum alloy ladders operates as follows:

[0045] like Figures 1 to 11As shown: The electric air inlet valve 1803 is connected to the external air supply pipe. First, the workpiece is clamped and fixed using the electric rotating clamping member 3, and the position of the workpiece to be cut is directly below the laser head 8. The first electric telescopic column 5 extends and lowers the laser cutting machine body 6, bringing the air nozzle 9 close to the workpiece. The laser cutting machine body 6 then operates, the laser head 8 emits a laser, and the clamping plate on the electric rotating clamping member 3 rotates, causing the workpiece to rotate, thus performing the laser cutting operation. At the same time, the electric air inlet valve 1803 is opened to allow air to enter the air-cooling channel 1801. As the air passes through the air-cooling channel 1801, it can cool and dissipate heat from the laser cutting machine body 6. The guide plate 1804 can guide the air onto the laser cutting machine body 6, so that... For better heat dissipation, air is then blown out sequentially through the first air blowing pipe 1805, the second air blowing pipe 1806, the third air blowing pipe 1807, and the air blowing hose 1809, and finally the air nozzle 9 blows air downwards, thereby blowing away the molten material at the cutting point and completely breaking the cut. During the process of blowing air onto the workpiece cutting point, liquid substances may splash onto the lens. After the workpiece is cut, the first electric telescopic column 5 retracts and raises the laser cutting machine body 6. The rangefinder 7 is a CF-1000PRO model. When the rangefinder 7 detects that the distance between the laser cutting machine body 6 and the workpiece exceeds the specified value, the second electric telescopic column 12 automatically extends, the first piston 14 moves downwards, and the moving plate 15 and the second... The compression frame 16 moves downward as a whole, thereby causing the movable rod 1107 at the top of the compression sleeve 1101 to move downward. The corresponding second movable block 1106 moves downward and compresses the first movable block 1105. The first movable block 1105, the moving frame 1108, and the rack 1110 move to the right as a whole. The two gears 1111, the rotating frame 1112, and the dust collection screen 1114 rotate 180 degrees as a whole. The dust collection screen 1114 is located to the right of the opening and closing part 1113. The third piston 1819 and the toothed plate 1820 move downward. The third air blowing pipe 1807 and the air blowing hose 1809 rotate 180 degrees as a whole. The air blowing hose 1809 is aligned with the lens inside the laser head 8. At the same time, the two second pistons 1816 move to the right under the action of hydraulic pressure. As the laser moves, the two second compression frames 1817 move to the right. The first rotating rod 1811 and the second rotating rod 1812 rotate and converge under the compression of the second compression frames 1817. The two clamping rods 1814 approach each other and clamp the air blowing hose 1809 into a duckbill shape. The air blowing hose 1809 blows air into the lens inside the laser head 8 to remove dust and splashed liquid from the lens. The dust and splashed liquid are blown onto the dust collection screen 1114. The opening and closing part 1113 will automatically rotate and open under the action of airflow. The gas is discharged through the two second through holes 1103. The sleeve 1101 can be removed by loosening the first bolt 1102. Then the dust collection screen 1114 can be removed by loosening the second bolt 1115 for easy cleaning or replacement.
