[0005] 2. Inefficient dust and smoke treatment: Molten particles and harmful gases (such as hydrogen cyanide produced by polyurethane combustion) generated during cutting are not discharged in time, polluting the working environment and affecting the life of equipment. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a laser cutting device for processing waterproof and heat-insulating materials.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The laser cutting device for processing waterproof and thermal insulation materials described in this utility model addresses the issue of material displacement during laser cutting. Since waterproof and thermal insulation materials are often low-density and porous, conventional fixtures can easily cause surface damage or displacement, leading to deviations in cutting accuracy. The adsorption mechanism below the worktable, connected to a vacuum pump (pumping speed 20m³ / h) via a solenoid valve assembly (model SMC VQZ315), generates an adsorption force of 0.02-0.08MPa. This force is directed through the adsorption pipe to the array of vacuum adsorption holes (diameter Φ5-8mm, spacing 50-100mm). Simultaneously, a liftable rubber strip (height 20-30mm) is installed at the edge of the worktable, driven by a telescopic cylinder (stroke 50mm, model Airtac SC63×50). This, combined with the adsorption mechanism, secures the material edges. This vacuum adsorption + elastic edge-pressing combination fixture solves the problem of easy displacement of low-density materials and improves positioning accuracy.

[0016] 2. In the laser cutting device for processing waterproof and thermal insulation materials described in this utility model, during the process of moving the laser module for cutting, the molten particles and harmful gases (such as hydrogen cyanide produced by the combustion of polyurethane) generated during cutting are not discharged in time, polluting the working environment and affecting the life of the equipment. The end of the dust collection pipe is connected to a multi-stage filtration mechanism, which includes a metal mesh primary filter (pore size 0.5mm), an activated carbon fiber adsorption layer (thickness 10mm) for adsorption, and an integrated fan (air volume 150-300m³ / h, model Schlebel GR280-2EK.6N) to form a negative pressure field (pressure -500Pa to -1000Pa) to ensure real-time collection of cutting fumes. The multi-stage filtration system improves the collection efficiency of cutting fumes and the removal rate of harmful gases, which meets the occupational exposure limits for hazardous factors in industrial workplaces as specified in GBZ 2.1-2019. Clean air is discharged to the outside through an external exhaust pipe (diameter Φ100mm) connected to the multi-stage filtration mechanism. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 2 , Figure 3 As shown in the figure, a laser cutting device for processing waterproof and thermal insulation materials according to an embodiment of the present invention includes a laser cutting mechanism 1, which includes an adjustment mechanism 12. A cutting component 3 is slidably connected to the outer track of the adjustment mechanism 12. A transmission seat 13 is fixedly connected to the opposite side of the rear end of the cutting component 3. A mating base 11 is slidably connected to the bottom of the adjustment mechanism 12. A processing table 14 is threadedly connected to the side of the mating base 11 near the cutting component 3. A processing module 2 is fixedly connected to the inner wall of the processing table 14. The processing module 2 includes an installation worktable 21. Telescopic cylinders 25 are fixedly connected to the back of both horizontal ends of the mounting table 21. The output end of the telescopic cylinder 25 is fixedly connected to the telescopic rod 23 that is slidably connected inside the mounting table 21. A rubber strip 24 is fixedly connected to the other end of the telescopic rod 23. A linear array of vacuum adsorption holes 22 is opened inside the mounting table 21. An adsorption mechanism 26 is fixedly connected to the other end of the vacuum adsorption hole 22. The adsorption mechanism 26 includes an adsorption pipe 27. A solenoid valve group 28 is fixedly connected to the other end of the adsorption pipe 27. A vacuum pump 29 is fixedly connected to the input end of the solenoid valve group 28.

[0025] When installing the waterproof and thermal insulation material, the board is placed above the workbench 21, and then the telescopic cylinders 25 at both ends are activated, causing the telescopic cylinders 25 to retract the telescopic rod 23, pressing the rubber strip 24 onto the surface of the board. After fixing, the vacuum pump 29 is activated. The vacuum pump 29 is driven by the solenoid valve group 28 and adsorbs into the vacuum adsorption hole 22 through the adsorption pipe 27, generating an adsorption force on the board above, so that the rubber strip cooperates with the vacuum adsorption to fix the edge of the material.

[0026] During the laser cutting process of waterproof and thermal insulation materials, when fixing the waterproof and thermal insulation material sheets, the materials are mostly low-density and porous structures. Conventional fixtures are prone to surface damage or displacement, resulting in deviations in cutting accuracy. However, the adsorption mechanism 26 under the installation workbench 21 is connected to a vacuum pump 29 (pumping speed 20m³ / h) through a solenoid valve group 28 (model SMC VQZ315). The adsorption force is 0.02-0.08MPa, which is generated by the adsorption pipe 27 to the array of vacuum adsorption holes 22 (diameter Φ5-8mm, spacing 50-100mm). At the same time, the liftable rubber pressure strip 24 (height 20-30mm) set on the edge of the workbench is driven by a telescopic cylinder 25 (stroke 50mm, model Airtac SC63×50). Together with the adsorption mechanism 26, the material edge is fixed. The vacuum adsorption + elastic edge pressing combination fixture solves the problem of easy displacement of low-density materials and improves positioning accuracy.

[0027] like Figure 1 , Figure 4As shown, the cutting assembly 3 includes a laser module 31, a laser cutting head 32 fixedly connected to the bottom of the laser module 31, an air pump 34 fixedly connected to the contact surface at the front end of the laser module 31, an air blowing pipe 33 fixedly connected to the output end of the air pump 34, the airflow direction of the air blowing pipe 33 is at an angle of 15°-30° with the beam of the laser cutting head 32, a multi-stage filtration mechanism 36 fixedly connected to the right contact surface of the laser module 31, a dust suction pipe 35 fixedly connected to the output end of the multi-stage filtration mechanism 36, the multi-stage filtration mechanism 36 includes a metal mesh primary filter, an activated carbon fiber adsorption layer, and a filter device integrated fan, a horizontal adjustment module 17 fixedly connected to the inner side of the slot of the adjustment mechanism 12, a transmission threaded column 15 meshingly connected to the inner side of the transmission seat 13, a drive motor 16 fixedly connected to the top of the transmission threaded column 15, and the lower part of the transmission seat 13 is slidably connected to the upper track of the adjustment mechanism 12.

[0028] During the cutting process, the molten particles and harmful gases (such as hydrogen cyanide produced by polyurethane combustion) generated during the cutting process are not discharged in time due to the adjustment mechanism 12 driving the laser module 31 to move. This pollutes the working environment and affects the life of the equipment. The end of the dust collection pipe 35 is connected to a multi-stage filtration mechanism 36. The multi-stage filtration mechanism 36 includes a metal mesh primary filter (pore size 0.5mm) and an activated carbon fiber adsorption layer (thickness 10mm) to adsorb the dust. The filtration device integrates a fan (air volume 150-300m³ / h, model Ziehl-Robbins GR280-2EK.6N) to form a negative pressure field (pressure -500Pa to -1000Pa) to ensure real-time collection of cutting fumes. The multi-stage filtration system improves the collection efficiency of cutting fumes and the removal rate of harmful gases, which meets the occupational exposure limits for hazardous factors in industrial sites. Clean air is discharged to the outside through the external exhaust pipe of the multi-stage filtration mechanism.

[0029] Air blowing pipe 33 (orifice diameter Φ3-5mm), air blowing pipe 33 is connected to high-pressure air pump 34 (pressure 0.5-1.0MPa), the airflow direction is at an angle of 15°-30° with the laser beam, used to blow away molten residue and assist in cooling;

[0030] The processing table 14 adopts a rectangular steel pipe welded frame, and the workbench 21 is fixedly installed on the inner wall of the processing table 14. The surface of the workbench is covered with an anti-slip rubber layer (thickness 3-5mm).

[0031] Working Principle: During the laser cutting of waterproof and thermal insulation materials, when fixing the waterproof and thermal insulation material sheets, the materials are mostly low-density porous structures. Conventional fixtures are prone to surface damage or displacement, leading to deviations in cutting accuracy. The adsorption mechanism 26 under the mounting table 21 is connected to a vacuum pump 29 (pumping speed 20m³ / h) via a solenoid valve group 28 (model SMC VQZ315). The adsorption force is 0.02-0.08MPa, which is generated by the adsorption pipe 27 to the array of vacuum adsorption holes 22 (diameter Φ5-8mm, spacing 50-100mm). At the same time, the liftable rubber pressure strip 24 (height 20-30mm) set on the edge of the worktable is driven by a telescopic cylinder 25 (stroke 50mm, model Airtac SC63×50), which works with the adsorption mechanism 26 to fix the material edge. The vacuum adsorption + elastic edge pressing combination fixture solves the problem of easy displacement of low-density materials and improves positioning accuracy.

[0032] During the cutting process, the laser module 31 is moved and cut by the adjustment mechanism 12. Molten particles and harmful gases (such as hydrogen cyanide produced by polyurethane combustion) generated during cutting are not discharged in time, polluting the working environment and affecting the life of the equipment. The end of the dust collection pipe 35 is connected to a multi-stage filtration mechanism 36. The multi-stage filtration mechanism 36 includes a metal mesh primary filter (pore size 0.5mm) and an activated carbon fiber adsorption layer (thickness 10mm) to adsorb the dust. The filtration device integrates a fan (air volume 150-300m³ / h, model Ziehl-Robbins GR280-2EK.6N) to form a negative pressure field (pressure -500Pa to -1000Pa) to ensure real-time collection of cutting fumes. The multi-stage filtration system improves the collection efficiency of cutting fumes and the removal rate of harmful gases, which meets the occupational exposure limits for hazardous factors in industrial sites. Clean air is discharged to the outside through the external exhaust pipe of the multi-stage filtration mechanism.
