Description

Technical Field

[0001] The invention relates to the field of laser cutting equipment, in particular to a laser cutting equipment capable of protecting a cutting environment. Background Art

[0002] Laser cutting equipment is a laser processing machine tool used to cut plates into workpieces of desired shapes. It uses the thermal energy of the laser beam to achieve cutting. Laser cutting is to use the energy released when the laser beam is irradiated onto the surface of the workpiece to melt and evaporate the workpiece to achieve the purpose of cutting and engraving. It has the characteristics of high precision, fast cutting, no restrictions on cutting patterns, automatic typesetting to save materials, smooth incisions, low processing costs, etc. It will gradually improve or replace traditional cutting process equipment.

[0003] Laser cutting equipment can produce strong light that can damage the eyes, cause stinging, and cause retinal damage. When the laser accidentally irradiates the skin, it can also cause burns and scars. When the laser comes into contact with the metal plate for cutting, the high temperature and gas combine to produce a large amount of dust. These smoke and dust contain a large amount of chemical components suspended in the air, causing damage to the human respiratory system. In the current existing technology, workers need to wear filters at all times to protect their eyes. At the same time, a negative pressure adsorption dust removal duct is connected to the inside of the laser cutting equipment material table, which can absorb smoke and dust from the bottom of the cut metal plate to reduce the spread of smoke and dust into the air.

[0004] In actual work, goggles can filter strong light, but the filtering effect of goggles will also make it difficult for workers to observe the slits of metal plates. This causes some workers to violate safety regulations and not wear glasses in order to clearly observe the slits, which will cause eye damage over time. During laser cutting, smoke and dust are mainly concentrated at the bottom of the metal plate, so most of the smoke and dust are absorbed by the dust removal system, but a small amount of smoke and dust is still generated above the metal plate to pollute the environment and cause damage to the human respiratory system. When the laser equipment initially contacts the metal plate, a large amount of high-temperature metal slag will be generated before the slit is formed. The slag splashes into the air, which is dangerous. Summary of the invention

At the same time, the lifting platform will lift up the metal material when it is raised. Therefore, when the staff deducts the material, the inclined plate of the lifting platform is less likely to scratch the material than the sawtooth platform. In addition, dragging the waste material on the inclined plate is more convenient and efficient than the sawtooth platform.

[0036] Embodiment 2 A laser cutting device capable of protecting the cutting environment, such as Figure 1-10 As shown, a plurality of waste boxes 3 are movably mounted inside the material platform frame 1 by setting a first mounting frame 2, and a plurality of hatches 5 are arranged on the side of the material platform frame 1, a plurality of hydraulic telescopic rods 4 are arranged inside the material platform frame 1, and a lifting platform 8 is installed on the top of the plurality of hydraulic telescopic rods 4, the lifting platform 8 includes an outer frame 801, and a plurality of inclined plates 802 are arranged inside the outer frame 801, and the lifting platform 8 can scrape off the slag attached to the sawtooth platform 7, and the lifting platform 8 includes a plurality of inclined plates 802, two sets of which are opposite to each other.

When the inclined plate 802 rises, the slag attached to the saw teeth can be scraped off, and the adjacent inclined plates 802 are located between each group of saw teeth to fill the gaps, thereby reducing the risk of small parts falling into the material table frame 1 when cut by the laser cutting equipment. At the same time, the lifting platform 8 will lift up the metal material when it rises, and the inclined plate 802 of the lifting platform 8 is less likely to scratch the material than the sawtooth platform 7 when the staff deducts the material, and dragging the waste on the inclined plate 802 is more convenient and efficient than the sawtooth platform 7.

[0037] See also Figure 4 , Figure 5 and Figure 6 A sawtooth platform 7 is movably mounted inside the material platform frame 1 by setting a second mounting frame 6, and the saw teeth of the sawtooth platform 7 correspond to the plurality of inclined plates 802. The slag attached to the sawtooth platform 7 can be scraped off by setting a lifting platform 8.

[0038] See also Fig.10 A dust removal duct 9 is arranged on the side of the material platform frame 1, and a connecting port 10 is arranged at one end of the dust removal duct 9, and the connecting port 10 is connected to the dust removal system through a hose. By setting the dust removal duct 9, the smoke and dust at the bottom of the metal plate can be collected from the inside of the material platform frame 1.

[0039] The working principle of the present invention is as follows: when a metal plate needs to be laser cut, the staff first places the metal plate to be cut above the sawtooth platform 7, then opens the dust removal system connected to the connection port 10, starts the moving mechanism 11, and then the crossbeam 1102 moves along the slide 1101 to the top of the metal plate under the action of the driving component, and then the first driving device 1103 starts to drive the first threaded rod 1106 to rotate, and the screw principle is used to make the moving seat 1105 slide outside the first slide rail 1104, so that the position of the moving seat 1105 is adjusted to drive the laser cutting mechanism 13 to further move to the accurate area of ​​the metal plate to be cut.

[0040] Next, the second driving device 1305 is started to drive the second threaded rod 1306 to rotate, and the lifting seat 1304 is slid outside the second slide rail 1303 by using the screw principle, and then the lifting seat 1304 moves to adjust the height of the laser cutter 1307, so that the height of the laser cutter 1307 is reduced to the cutting height, and the laser cutter 1307 is started to cut the metal plate. When the lifting seat 1304 descends, the rack 1308 and the first gear 1312 are engaged, and then the first gear 1312 drives the fixed rod 1309 to rotate, and further the fixed rod 1309 drives the first bevel gear 1310 to rotate through the transmission belt assembly 1311. The rotation of the first bevel gear 1310 will simultaneously drive the second bevel gear 1319 and the third bevel gear 1321 to rotate, and then the second gear 1320 and the third gear 1322 start to rotate. Because the second gear 1320 is engaged with the first half gear ring 1316, the third gear 1322 The first half gear ring 1316 and the second half gear ring 1317 are meshed with each other, so the first half gear ring 1316 and the second half gear ring 1317 extend outward from the inside of the semi-arc clamping plate 1313 respectively, so that the two groups of second filter plates 1318 respectively installed on the sides of the first half gear ring 1316 and the second half gear ring 1317 are close to each other to achieve closure. In the process of the two groups of second filter plates 1318 approaching each other, the scraper 1315 on the side of the first filter plate 1314 will scrape the inner side of the second filter plate 1318, which can clean the inner side of the second filter plate 1318. The slag generated by the laser cutter 1307 when it initially contacts the metal plate will be blocked by the first filter plate 1314 and the second filter plate 1318 to reduce the slag splashing, facilitate later cleaning, and improve the safety of the equipment. The smoke and dust generated by the cutting will be sucked away and concentratedly purified by the dust removal system connected to the top of the protective cover 1323, and the smoke and dust at the bottom of the metal plate will be sucked away and concentratedly purified by the dust removal pipe 9.

[0041] When the metal plate cutting is completed and the staff needs to unload the material, the hydraulic telescopic rod 4 is started to push the lifting platform 8 to rise, and then the inclined plate 802 will scrape off the slag attached to the serrated platform 7, and the scraped slag will fall into the waste box 3. The staff can regularly open the hatch 5 to clean the waste box 3. When the lifting platform 8 rises, the cut metal plate will also rise. The staff will collect all the required materials, and then transport the remaining waste to the designated area.
