Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment for metal processing, and in particular to a two-stage dynamic collection device for cutting fumes. Background Technology

[0002] When using a gantry CNC cutting machine for material cutting, the dust spreads rapidly. Plasma cutting of metal composite plates (such as titanium plates and stainless steel composite plates) generates high-temperature, high-concentration dust (containing metal particles, oxides, and toxic gases). Traditional bottom-filled dust collection devices and fixed dust collection devices cannot collect dust in real time along with the cutting point, resulting in low collection efficiency and limited coverage of a single dust collection port. Dust easily escapes into the workshop, leading to a deterioration of the working environment and harming the health of operators. Secondary pollution and residual dust settle in the workshop, making cleaning difficult. Long-term accumulation affects equipment lifespan and product cleanliness. It is necessary to solve the problem of cutting dust. Therefore, a two-stage dynamic collection device for cutting dust was designed. Utility Model Content

Therefore, one objective of this invention is to propose a dual-stage dynamic collection device for cutting smoke and dust, achieving dual-stage capture of smoke, improving smoke cleaning efficiency, and protecting the working environment.

The gantry-type CNC cutting machine is externally arranged with a frame. Multiple crossbeams are movably mounted on the surface of the frame. Connecting rods are movably installed between the crossbeams. A roof is commonly mounted on the exterior of the multiple crossbeams. A support frame is fixed on one side of the frame. An air duct is fixed on the top of the support frame. Multiple air guide pipes are fixed on the surface of the air duct. Multiple suction pipes are fixed on the surface of each air guide pipe. The suction pipes penetrate the roof and extend below the roof.

[0005] An air hood is fixed to the cutting end surface of the gantry CNC cutting machine, and a fan is fixed to the lower surface of the support frame. The input end of the fan is fixed to the air hood and connected to an exhaust hose, and the output end of the fan is fixed to the air duct and connected to an exhaust pipe.

[0006] Preferably, a guide rod is fixedly installed through the surface of the ceiling, a movable component is movably mounted on the surface of the guide rod, and an elastic connector is provided between the movable component and the exhaust hose.

[0007] Preferably, the elastic connector includes an elastic rope, and a first set of rings and a second set of rings are fixed to both ends of the elastic rope.

[0008] Preferably, the first set of rings is fitted onto the surface of the movable part, and the second set of rings is movably fitted onto the surface of the exhaust hose.

[0010] Preferably, a negative pressure pump is installed at the end of the air duct.

Detailed Implementation

[0021] Reference Figure 1-4A dual-stage dynamic collection device for cutting fumes includes a gantry-type CNC cutting machine 1. The gantry-type CNC cutting machine 1 is externally arranged with a frame 2. Multiple crossbeams 3 are movably mounted on the surface of the frame 2. Connecting rods 4 are movably installed between the crossbeams 3. The multiple crossbeams 3 are collectively mounted with a roof 5. A support frame 6 is fixed on one side of the frame 2. An air duct 7 is fixed on the top of the support frame 6. Multiple air guide pipes 8 are fixed on the surface of the air duct 7. Multiple suction pipes 9 are fixed on the surface of each air guide pipe 8. The suction pipes 9 pass through the roof 5 and extend to the bottom of the roof 5. The roof 5 is arc-shaped to improve the gas collection effect and guide the cutting fumes to gather at the top of the roof 5. The fumes are then extracted by the suction pipes 9. This arrangement can maximize the absorption of cutting fumes and prevent the fumes from escaping. The suction pipes 9 are distributed in a herringbone pattern, with the density decreasing from the center to both sides.

[0022] Unlike movable sheds, this dual-stage dynamic collection device is more suitable for cutting small and medium-sized plates. It is suitable for table mounting, with the shed frame 2 and the gantry CNC cutting machine 1 fixed together on the same horizontal plate, which can realize integrated assembly and transportation, and the structure is lighter.

[0023] A gas hood 10 is fixed to the surface of the cutting end 101 of the gantry CNC cutting machine 1. The cutting end 101 is a structure inherent in the gantry CNC cutting machine 1 itself, used for cutting materials. It is a structure inherent in the existing technology. A fan 11 is fixed to the lower surface of the support frame 6. The input end of the fan 11 is fixed to the gas hood 10 and connected to an exhaust hose 12. The output end of the fan 11 is fixed to the air duct 7 and connected to an exhaust pipe 13. By assembling the fan 11, the suction is increased, and the cutting fumes generated near the cutting end 101 are sucked up.

[0024] A guide rod 14 is fixedly fixed through the surface of the ceiling 5. A movable part 15 is movably installed on the surface of the guide rod 14. An elastic connector 16 is provided between the movable part 15 and the exhaust hose 12. The elastic connector 16 includes an elastic rope 161. A first set of rings 162 and a second set of rings 163 are fixed at both ends of the elastic rope 161, respectively. The first set of rings 162 is fitted on the surface of the movable part 15, and the second set of rings 163 is movably fitted on the surface of the exhaust hose 12.

[0025] The guide rod 14 has threads at both ends, and the canopy 5 has symmetrical mounting holes on its side. The guide rod 14 is passed through the mounting holes at both ends of the canopy 5, and locking nuts are then threaded onto the surface of the guide rod 14 and located at both ends of the canopy 5. The canopy 5 can be made of fabric cut and sewn, such as canvas, which has high strength.

[0026] The movable part 15 can slide on the surface of the guide rod 14, and the second set of rings 163 can slide on the surface of the exhaust hose 12. The installation position of the fan 11 can be set close to the center line of the gantry CNC cutting machine 1. This arrangement minimizes the length of the exhaust hose 12. When the gantry CNC cutting machine 1 is operating, the exhaust hose 12 moves with the position of the cutting end 101 and the air hood 10. At this time, the second set of rings 163 slides on the surface of the exhaust hose 12, the movable part 15 slides on the surface of the guide rod 14, and the elastic rope 161 adapts to the extension and contraction. Through the flexible position adjustment of the second set of rings 163, the movable part 15, and the elastic rope 161, the exhaust hose 12 is placed in a suitable spatial position. The exhaust hose 12 will not fall into the gantry CNC cutting machine 1 and affect the cutting operation. It also realizes that the air hood 10 follows the cutting end 101 as the cutting position is adjusted, and realizes the extraction of cutting fumes.

[0027] The scaffold 2 has multiple support rods 201 fixed inside for mounting the crossbeams 3.

[0028] A negative pressure pump and a main exhaust system are installed at the end of the duct 7 to provide negative pressure inside the duct 7, thereby extracting the cutting flue gas. A filtration system can also be installed at the end of the duct 7 to centrally treat the collected flue gas. The treated flue gas that meets the emission standards is then discharged into the atmosphere.

[0029] When using this device, the worker moves the sheet metal to the cutting base surface of the gantry CNC cutting machine 1. First, the negative pressure pump and fan 11 are started. At this time, negative pressure is generated in the air duct 7. The suction pipe 9 draws out the accumulated cutting fumes to achieve primary dust collection. Simultaneously, the fan 11 draws out the cutting fumes around the air hood 10 to achieve secondary dust collection and introduces the fumes into the air duct 7. The air hood 10 cannot completely extract the fumes, and the escaping fumes accumulate in the ceiling 5. The suction pipe 9 draws the fumes into the air duct 7. The fumes collected by the primary and secondary dust collection are collected through the air duct 7. The dual extraction of fumes improves the fumes cleaning effect, protects the working environment, and ensures the health of the operator.
