Description

Technical Field

[0001] This utility model relates to a dust removal device, specifically a follow-up dust removal device suitable for large-format laser cutting machines. Background Technology

[0002] The mainstream dust removal method for existing laser cutting machines is zoned dust removal. This involves controlling the flue dampers, which open and close as the gantry moves to ensure optimal smoke extraction. However, this method is less adaptable to larger-format laser cutting machines. If the cut plate is not a single piece, the overall dust removal effect will be significantly affected. Alternatively, the performance of the dust collector or dust collector fan may need to be improved to ensure sufficient suction power and achieve the desired effect. However, even then, some smoke may still escape, resulting in a less than ideal outcome.

[0003] Currently, a utility model patent with publication number CN222626482U discloses a follow-up smoke exhaust structure for a laser cutting machine, including a machine tool, a gantry, and a machine head. A mounting assembly is detachably connected to the lower part of the machine head, and a horizontally sliding smoke exhaust assembly is movably connected to the mounting assembly. The smoke exhaust assembly includes a smoke exhaust duct with its opening facing directly below the machine head. A filter box communicating with the smoke exhaust duct is bolted to one side of the gantry, and an air pump for exhausting gas from inside the filter box is located on one side of the filter box. This design, by detachably connecting the mounting assembly to the lower part of the machine head, allows the device to better adapt to different types of laser cutting machines. The smoke exhaust assembly is movably connected below the mounting assembly, and the smoke exhaust duct in the smoke exhaust assembly is connected to the filter box via a connecting pipe, thereby increasing the airflow velocity and improving the absorption effect of external smoke.

[0004] As can be seen from the above-disclosed technical content, as prior art, the utility model with announcement number CN222626482U, by detachably connecting and installing components below the machine head, allows the device to better adapt to different types of laser cutting machines. The smoke exhaust component is movably connected below the installation component, and the smoke exhaust duct in the smoke exhaust component is connected to the filter box through the connecting pipe, thereby increasing the airflow velocity and improving the absorption effect of external smoke. However, the overall structure of this patent is complex and the cost is high, making it difficult to promote on a large scale. At the same time, the smoke is mainly discharged through the connecting pipe, the connecting screw sleeve, and the air pipe. During use, the particulate dust in the smoke will gradually accumulate in the connecting pipe, the connecting screw sleeve, and the air pipe, reducing the dust collection capacity and thus increasing its maintenance and use costs. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a follow-up dust removal device suitable for large-format laser cutting machines. It can be easily inspected and maintained, and can operate more reliably and for longer periods of time. It can also achieve better dust removal results and is suitable for large-format laser plate cutting machines.

[0006] To achieve the above objectives, this utility model is applicable to a follow-up dust removal device for a large-format laser cutting machine, comprising a gantry frame and a laser cutting head. The laser cutting head is movably mounted on the gantry frame, which is movably mounted on the machine bed. A control console is mounted on the side of the machine bed via a bracket. A dust removal device is fixedly mounted on the lower surface of the gantry frame. The dust removal device also includes an air duct housing and an axial flow fan. Multiple through holes are equally spaced on the lower surface of the air duct housing, and axial flow fans are installed in the through holes. The central axis of the axial flow fan is inclined towards one side of the laser cutting head, and the central axes of the multiple axial flow fans are parallel to each other. A control switch and an axial flow fan speed adjustment knob are provided on the side of the control console.

[0007] As a further improvement of this utility model, the cross-section of the air duct shell is a right trapezoid, with the inclined side of the right trapezoid facing down and having a through hole, into which an axial fan is installed.

[0008] As a further improvement of this utility model, the air duct housing is installed on the lower surface of the gantry frame by screws or brackets.

[0009] As a further improvement of this utility model, the air duct shell is made of metal.

[0010] As a further improvement of this utility model, the axial fan is installed in the air duct housing by screws or brackets.

[0011] As a further improvement of this utility model, the midpoint section of the inner side of the air duct shell is closed by a central partition.

[0012] By employing the above-described solution, this utility model possesses at least the following advantages: A dust removal device is installed under the gantry frame. The duct housing of this dust removal device is separated by a central partition. Axial flow fans are symmetrically installed on both sides of the duct housing, with one side installed in opposite directions within the duct housing. Due to the inclined surface of the duct housing, the installed axial flow fans face the laser cutting head. When the axial flow fans are turned on, the flue gas near the center of the cutting surface enters the flue gas duct within the duct housing due to the suction force of the axial flow fans. It then moves to both sides along the flue gas direction. Upon reaching the end face, the flue gas is again drawn out by the suction force of the axial flow fans and blown to the partitioned dust removal duct openings of the bed, where it is drawn away by the dust collector, achieving a better dust removal effect.

[0014] The following description, in conjunction with the accompanying drawings, describes the following utility model of a follow-up dust removal device suitable for large-format laser cutting machines.

[0015] In Embodiment 1 of this application, as Figures 1 to 4 As shown, this invention, applicable to large-format laser cutting machines, includes a gantry frame 1, a dust removal device body 2, and a laser cutting head 7. The laser cutting head 7 is movably mounted on the gantry frame 1, and the gantry frame 1 is movably mounted on the bed 6. A control console 5 is mounted on the side of the bed 6 via a bracket. The dust removal device body 2 is fixedly mounted on the lower surface of the gantry frame 1. The dust removal device body 2 also includes a duct housing 21 and an axial flow fan 22. Multiple through holes are equally spaced on the lower surface of the duct housing 21, and axial flow fans 22 are installed in the through holes. When the equipment is running, the axial flow fan 22 near the central partition 23 draws the dust into the duct housing 21, and the axial flow fans 22 at both ends of the duct housing 21 blow the flue gas outward for easy recovery by the flue gas recovery device. The central axis of the axial flow fan 22 is inclined towards one side of the laser cutting head 7, and the central axes of the multiple axial flow fans 22 are parallel to each other. A control switch 3 and an axial flow fan speed adjustment knob 4 are provided on the side of the control console 5. The cross-section of the air duct housing 21 is a right-angled trapezoid, with the inclined side of the right-angled trapezoid facing downwards and having a through hole. An axial flow fan 22 is installed inside the through hole. When the central baffle 23 is not installed inside the air duct housing 21, the axial flow fan 22 on the surface of the air duct housing 21 draws the cutting fumes into the air duct housing 21. Only the axial flow fan 22 at the end of the air duct housing 21 is used to blow the fumes inside the air duct housing 21 to the partition dust removal damper on one side of the bed 6, so that the dust removal duct behind the partition dust removal damper can draw away the fumes. This arrangement can reduce the number of partition dust removal dampers and dust removal ducts required for the equipment, thereby saving costs.

[0016] A laser cutting machine follow-up smoke exhaust structure (hereinafter referred to as "the patent") with utility model announcement number CN222626482U, through a detachable mounting component connected below the machine head, allows the device to better adapt to different types of laser cutting machines. The smoke exhaust component is movably connected below the mounting component, and the smoke exhaust duct in the smoke exhaust component is connected to the filter box through a connecting pipe, thereby increasing the airflow velocity and improving the absorption effect of external smoke. However, the overall structure of the patent is complex and the cost is high, making it difficult to promote on a large scale. At the same time, the smoke is mainly discharged through the connecting pipe, the connecting screw sleeve and the air pipe. During use, the particulate dust in the smoke will gradually accumulate in the connecting pipe, the connecting screw sleeve and the air pipe, reducing the dust collection capacity and thus increasing its maintenance and use costs. In contrast, the dust removal device body 2 of the present invention has a right-angled trapezoidal cross-section of the air duct shell 21 and is equipped with a maintenance window, which makes maintenance convenient, and the installation and use costs are very low, making it easy to promote on a large scale.

[0017] This embodiment is basically the same as the first embodiment in structure. The difference is that the midpoint section of the inner side of the air duct shell 21 is closed by the central partition 23, which shortens the length of the air duct shell 21 on both sides of the central partition 23, thereby reducing the pressure of the axial fan 22 and allowing the dust removal flue behind the partition dust removal dampers on both sides of the bed 6 to draw away the flue gas. This arrangement can effectively improve the flue gas absorption and treatment capacity and cope with environments with a large amount of flue gas.

[0018] To further optimize the working efficiency of this application and facilitate maintenance, the air duct housing 21 is mounted on the lower surface of the gantry frame 1 using screws or brackets. To improve durability, the air duct housing 21 is made of machined metal. To facilitate adjustment of the direction of the axial fan 22, the axial fan 22 is mounted in the air duct housing 21 using screws or brackets.

[0019] When using this device, simply install the follow-up dust removal device suitable for large-format laser cutting machines and connect the corresponding wiring equipment to put it into use.

[0020] When this utility model is used, its specific operation is as follows: like Figures 1 to 4 As shown, when the laser cutting head 7 is driven by the gantry 1 to cut, the dust removal device body 2 moves with the gantry 1. Because the air duct housing 21 has an inclined surface, the installed axial fan 22 faces the laser cutting head 7. When the axial fan 22 is turned on, the flue gas near the middle of the cutting surface enters the air duct housing 21 from direction C due to the suction force of the axial fan 22. The flue gas moves towards direction D in the air duct housing 21. When it reaches the end face of the air duct housing 21, the flue gas is also drawn out by the suction force of the axial fan 22 and blown towards direction E to the partitioned dust removal air duct opening of the bed 6, where it is drawn away by the dust collector, achieving a better dust removal effect.

[0021] In summary, the following embodiment of the present invention provides a follow-up dust removal device for large-format laser cutting machines. By installing a dust removal device 2 under the gantry frame 1, the air duct housing 21 of the dust removal device body 2 is separated by a central partition 23. Axial flow fans 22 are symmetrically installed on both sides of the air duct housing 21, with one side installed in a reverse orientation within the air duct housing 21. Because the air duct housing 21 has an inclined surface, the installed axial flow fans 22 face the laser cutting head 7. When the axial flow fans 22 are turned on, the flue gas near the center of the cutting surface enters the flue gas duct of the air duct housing 21 due to the suction force of the axial flow fans 22. The gas moves to both sides along the flue gas duct direction, and upon reaching the end face, it is again drawn out by the suction force of the axial flow fans 22 and blown to the partitioned dust removal air duct opening of the bed 6, where it is drawn away by the dust collector, achieving a better dust removal effect.
