Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, specifically to a high-efficiency laser cutting machine. Background Technology

[0002] A laser cutting machine uses a laser beam emitted from a laser source, which is focused into a high-power-density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a kerf is eventually formed in the material, thus achieving the purpose of cutting.

[0003] According to publication number CN217253683U, a high-efficiency laser cutting machine is described. Before cutting, the guide rod is pulled relative to the cutting table to adjust the distance between the limit bar and the cutting table, effectively isolating and protecting the working area. The workpiece is placed on the surface of the serrated metal support plate of the cutting table, and the laser cutting blade is driven by the cutting blade holder to cut the workpiece. Two sets of filter boxes are installed under the dust collection hood. During laser cutting, the molten or gasified metal waste blown away by high-pressure gas enters the filter box under the negative pressure of the induced draft fan. The high-temperature resistant filter screen filters and removes impurities from the gas mixed with waste waste, effectively purifying the exhaust gas generated during the cutting process.

[0004] The high-temperature resistant filter screen can filter waste residue and purify exhaust gas. However, during the use of laser cutting machines, not only will waste residue be generated, but the materials will also melt, evaporate and decompose under the action of high-temperature laser, thereby releasing various harmful gases. Direct discharge not only pollutes the surrounding air, but also damages the health of workers who inhale them for a long time. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figure 1 and Figure 5As shown in this embodiment, a high-efficiency laser cutting machine includes a movable base 1. A support rod 2 is fixedly connected to the top of the movable base 1. A protective cover 3 is fixedly connected to the top of the support rod 2. A first motor 4 is fixedly connected to the front of the protective cover 3. A rotating block 5 is fixedly sleeved on the output shaft of the first motor 4. A gas collecting plate 6 is fixedly connected to the bottom of the rotating block 5. A filter screen 7 is provided inside the gas collecting plate 6. A connecting pipe 8 is fixedly connected to the side of the gas collecting plate 6 near the rotating block 5. A fan 9 is fixedly connected to the end of the connecting pipe 8 away from the gas collecting plate 6. A conduit 10 is fixedly connected to the side of the fan 9 near the first motor 4. A processing box 11 is fixedly connected to the side of the conduit 10 away from the fan 9. A liquid inlet pipe 12 is fixedly connected to the back of the processing box 11.

[0024] By starting the fan 9, a negative pressure suction is formed inside the gas collection plate 6, thereby collecting the fumes generated during processing into the gas collection plate 6. Foreign objects and dust are filtered and intercepted by the filter screen 7. The fumes enter the duct 10 through the connecting pipe 8 and are absorbed by the treatment liquid inside the treatment box 11, thereby removing harmful gases from the fumes and ensuring the cleanliness of the discharged gas.

[0025] By setting a rotating block 5 on the gas collecting plate 6 and fixing the rotating block 5 to the output end of the first motor 4, the first motor 4 can be started when the gas collecting plate 6 is working, thereby driving the rotating block 5 and the gas collecting plate 6 to rotate and adjust their tilt angle to facilitate the intake of flue gas. The protective cover 3 is located outside the laser cutting head 24 and can collect the generated flue gas so that the gas collecting plate 6 can collect the gas. The protective cover 3 also provides a certain degree of protection for the laser cutting head 24.

[0026] The protective cover 3 is located outside the movable base 1. The fan 9 and the treatment box 11 are fixedly connected to the protective cover 3. A drain pipe is provided on the side of the treatment box 11 away from the protective cover 3. Solenoid valves are installed inside the drain pipe and the liquid inlet pipe 12.

[0027] An air outlet pipe 13 is fixedly connected to the top of the treatment box 11. A pad 14 is fixedly connected to the inner wall of the air outlet pipe 13. A filter element 15 is provided at the top of the pad 14. A connecting spring 16 is provided at the top of the filter element 15.

[0028] The top of the air outlet duct 13 is provided with a fixing groove 17, and a fixing block 18 is provided inside the fixing groove 17. A dustproof net 19 is fixedly connected to the top of the fixing block 18.

[0029] By installing a filter element 15 inside the air outlet duct 13, secondary treatment is achieved after the flue gas is absorbed by the treatment liquid to ensure the treatment effect. A connecting spring 16 is installed between the filter element 15 and the dustproof net 19. The spring force can be used to position the filter element 15. When the filter element 15 needs to be replaced, the dustproof net 19 is rotated, which causes the fixing block 18 to rotate in the fixing groove 17. After rotating a certain angle, the dustproof net 19 is pulled upward to disassemble the fixing block 18 from the fixing groove 17, thereby disassembling and replacing the filter element 15.

[0030] There are four fixing slots 17, which are L-shaped and are fixedly connected to the dustproof net 19 and the connecting spring 16.

[0031] The movable base 1 is internally slidably connected to a first slide rod 20. The front and rear sides of the first slide rod 20 are fixedly connected to a connecting frame 21. The front of the connecting frame 21 is fixedly connected to a second motor 22. The output shaft of the second motor 22 is fixedly connected to a first screw 23. The first screw 23 is threadedly connected to the movable base 1. A laser cutting head 24 is fixedly connected to the side of the movable base 1 near the gas collecting plate 6.

[0032] A support frame 25 is provided at the bottom of the connecting frame 21. A connecting plate 26 is fixedly connected to the top of the support frame 25. A third motor 27 is fixedly connected to the right side of the connecting plate 26. A second screw 28 is fixedly connected to the output shaft of the third motor 27. A second slide rod 29 is fixedly connected to the inner wall of the connecting plate 26. The second slide rod 29 and the connecting frame 21 are slidably connected.

[0033] By activating the second motor 22 and the third motor 27, the first screw 23 and the second screw 28 are rotated, the moving seat 1 slides on the surface of the first slide rod 20, and the connecting frame 21 slides on the surface of the second slide rod 29, thereby adjusting the longitudinal and lateral positions of the laser cutting head 24 to facilitate cutting at different positions of the product. A conical collection plate is provided at the bottom of the support frame 25 to facilitate the collection of waste residue for unified treatment.

[0034] This utility model provides a high-efficiency laser cutting machine, the specific working principle of which is as follows:

[0035] In use, the product to be processed is placed on the support frame 25. By controlling the second motor 22 and the third motor 27, the first screw 23 and the second screw 28 are driven to rotate respectively. The longitudinal and lateral positions of the laser cutting head 24 can be adjusted to facilitate cutting at different positions of the product. At the same time, the fan 9 is started to create a negative pressure suction inside the gas collection plate 6, thereby collecting the fumes generated during processing into the gas collection plate 6. Foreign objects and dust are filtered and intercepted by the filter screen 7. The fumes enter the duct 10 through the connecting pipe 8 and are absorbed by the treatment liquid inside the treatment box 11, thereby removing harmful gases from the fumes. The treated gas moves upward and passes through the filter element 15 for secondary treatment to improve the cleaning effect, and is discharged from the top of the exhaust pipe 13.
