[0006] Each of the dust removal components includes a duct, a damper, a drive unit, and a protective cover. The duct has an air inlet surface on the side facing the processing area, and the air inlet surface has a first air hole. The damper is slidably disposed on the air inlet surface and has a second air hole. The drive unit can drive the damper to slide to connect or disconnect the second air hole from the first air hole.

[0007] A baffle is provided on the top of the air duct; the protective cover is provided on the outer side of the air duct and is connected to the side of the baffle away from the processing area.

[0034] During the cutting process of a cutting machine, a large amount of smoke and pungent odors are generated, which endangers the health of operators and pollutes the working environment. Currently, dust removal devices are mainly used to clean up the smoke and odors generated during the cutting process. However, in actual production, researchers have found that traditional dust removal devices usually install the drive unit inside the air duct. This means that the chips and sparks generated during the cutting process can easily fall onto the drive unit, causing damage and affecting the service life of the dust removal device. Furthermore, because the drive unit is installed inside the air duct, it usually requires multiple access ports to be opened on the air duct, which increases the difficulty of installation and maintenance of the drive unit.

[0035] This utility model proposes a dust removal device and a cutting equipment, aiming to solve the technical problems of short service life, difficult installation and maintenance of dust removal devices.

[0036] Please see Figures 1 to 5 In one embodiment of this utility model, the dust removal device includes two dust removal components 1 spaced apart, with a processing area 2 between the two dust removal components 1; each dust removal component 1 includes a duct 100, a damper 200, a drive component 300, and a protective cover 400. The side of the duct 100 facing the processing area 2 is provided with an air inlet surface 110, and the air inlet surface 110 is provided with a first air hole 111. The damper 200 is slidably disposed on the air inlet surface 110, and the damper 200 is provided with a second air hole 210; the drive component 300 can drive the damper 200 to slide, so as to connect or disconnect the second air hole 210 from the first air hole 111; a baffle 120 is provided on the top of the duct 100; the protective cover 400 is disposed on the outer side of the duct 100 and connected to the side of the baffle 120 away from the processing area 2. The protective cover 400, the baffle 120, and the outer side of the duct 100 surround to form an installation cavity, and the drive component 300 is disposed in the installation cavity.

[0037] The technical solution of this utility model, by installing the drive component 300 within the mounting cavity formed by the protective cover 400, the outer side of the air duct 100, and the baffle 120, can prevent the chips and sparks generated during the cutting process from falling onto the drive component 300, thereby better protecting the drive component 300 and extending the service life of the dust removal device. In this embodiment, the air inlet surface 110 of the air duct 100 has a first air hole 111, and the air damper 200 has a second air hole 210; the drive component 300 can drive the air damper 200 to slide during the cutting operation to open the first air hole 111 and the second air hole 210, thereby cleaning up the smoke and pungent odor generated during the cutting process, and disconnecting the first air hole 111 and the second air hole 210 when no cutting operation is being performed, thereby cutting off the internal space of the air duct 100 from the external environment. By installing the drive component 300 within the mounting cavity formed by the protective cover 400, the baffle 120, and the outer side of the duct 100, the drive component 300 can be isolated, thus preventing chips and sparks generated during the cutting process from falling onto it, better protecting the drive component 300, and extending the service life of the dust removal device. The baffle 120 extends upwards from the top of the duct 100, blocking flying chips and sparks during the cutting process, further protecting the drive component 300. Simultaneously, the drive component 300, the protective cover 400, and the baffle 120 are all installed on the outer side of the duct, reducing the difficulty of installation and maintenance of the drive component 300.

[0038] It should be noted that during the cutting operation, the exhaust fan needs to be connected to the air duct 100, and the exhaust fan provides suction to draw the chips and sparks generated during cutting into the air duct 100. In this embodiment, the driving component 300 can be a driving cylinder or a driving hydraulic cylinder.

[0039] In one embodiment of this utility model, the air inlet surface 110 is provided with a plurality of first air holes 111 spaced apart along the length direction of the air duct 100, and the damper 200 is provided with a plurality of second air holes 210 spaced apart along the length direction of the air duct 100, and the number of second air holes 210 is equal to the number of first air holes 111; the driving member 300 can drive the damper 200 to slide, so as to connect or disconnect each second air hole 210 from the corresponding first air hole 111. In this embodiment, by setting the number of both first air holes 111 and second air holes 210 to a plurality, more air intake channels can be provided, thereby improving the dust removal efficiency of the dust removal device.

[0040] In one embodiment of this utility model, the air inlet surface 110 is provided with a guide rod 112, and the damper 200 is provided with a guide groove 220, with the guide rod 112 slidably disposed in the guide groove 220. In this embodiment, by slidably disposing the guide rod 112 in the guide groove 220, it can provide guidance for the sliding of the damper 200, thereby improving the stability of the damper 200 during sliding. In a specific embodiment, to further improve the stability of the damper 200 during sliding, the number of guide rods 112 can be set to multiple, and all multiple guide rods 112 can be slidably disposed in the guide groove 220.

[0041] In one embodiment of this utility model, a limiting block 1121 is provided at the end of the guide rod 112 away from the air inlet surface 110, and the limiting block 1121 can abut against the damper 200. In this embodiment, the limiting block 1121 can abut against the damper 200 to restrict the position of the damper 200, thereby reducing the risk of the guide rod 112 disengaging from the guide groove 220. In this embodiment, the first air hole 111 and the second air hole 210 have the same shape and size, and the distance between two adjacent first air holes 111 is greater than or equal to the width of the corresponding second air hole 210, and correspondingly, the distance between two adjacent second air holes 210 is greater than or equal to the width of the corresponding first air hole.

[0042] In one embodiment of this utility model, a bending plate 230 is provided on the top of the damper 200, and the driving member 300 is disposed on the top of the duct 100, with the output end of the driving member 300 connected to the bending plate 230. In this embodiment, the damper 200 is connected to the output end of the driving member 300 through the bending plate 230 at the top, which simplifies the structure of the dust removal device and reduces the manufacturing difficulty of the dust removal device. It should be noted that when the output end of the driving member 300 is connected to the bending plate 230 at the top of the damper 200, the output end of the driving member 300 is located outside the mounting cavity. At this time, the baffle 120 can block the chips and sparks splashed during the cutting process, thereby preventing the chips and sparks generated during the cutting process from falling onto the output end of the driving member 300, better protecting the driving member 300, and extending the service life of the dust removal device.

[0043] In one embodiment of this utility model, the baffle 120 is provided with a strip-shaped hole 121, and the bending plate 230 is provided with a limiting plate 231, which is slidably disposed in the strip-shaped hole 121. The baffle 120 is also provided with a clearance hole 122 for the bending plate 230 to be inserted, and the clearance hole 122 communicates with the strip-shaped hole 121. When the limiting plate 231 abuts against one end of the strip-shaped hole 121, the second air hole 210 is connected to the first air hole 111; when the limiting plate 231 abuts against the other end of the strip-shaped hole 121, the second air hole 210 is disconnected from the first air hole 111. In this embodiment, the strip-shaped hole 121 is used to limit the range of motion of the limiting plate 231, thereby limiting the range of motion of the damper 200. Specifically, when the limiting plate 231 moves to one end of the strip hole 121, the second air hole 210 of the damper 200 is connected to the first air hole 111 of the air inlet surface 110. At this time, controlling the operation of the exhaust fan can clean up the smoke and pungent odor generated during the cutting process. When the limiting plate 231 moves to the other end of the strip hole 121, the second air hole 210 of the damper 200 is disconnected from the first air hole 111 of the air inlet surface 110, that is, the damper 200 blocks the first air hole 111. At this time, the internal space of the duct 100 and the external environment can be cut off.

[0044] In one embodiment of this utility model, both the first air hole 111 and the second air hole 210 are elongated. In this embodiment, both the first air hole 111 and the second air hole 210 are elongated and extend along the height direction of the duct 100. Designing both the first air hole 111 and the second air hole 210 as elongated structures extending along the height direction of the duct 100 allows for more air holes to be opened on the air inlet surface 110, thereby improving dust removal efficiency. Alternatively, the first air hole 111 and the second air hole 210 can also be square, circular, etc.

[0045] In one embodiment of this utility model, the side of the air duct 100 facing the processing area 2 is provided with multiple air inlet surfaces 110. The number of air dampers 200, driving components 300, baffles 120 and protective covers 400 are all multiple. The number of air dampers 200, driving components 300, baffles 120 and protective covers 400 is equal to the number of air inlet surfaces 110, and the air dampers 200, driving components 300, baffles 120, protective covers 400 and air inlet surfaces 110 are arranged in a one-to-one correspondence.
