Dust removal air pipe structure and laser processing dust removal structure

Abstract

This utility model discloses a dust removal duct structure and a laser processing dust removal structure, including a shell, which includes a side plate 1 and a side plate 2 arranged on both sides, and a spiral shell portion connecting the side plate 1 and the side plate 2. Dustproof laser glass is embedded in the side plate 1, and the middle of the side plate 2 forms an exhaust port, which is directly facing the object or area to be dusted. The spiral shell portion extends along the spiral direction and together with the side plate 1 and the side plate 2 forms a pipe opening, which is connected to external dust removal equipment through a pipe section. Through the setting of the spiral shell portion, combined with the pipe opening and the exhaust port, dust can be drawn from the object or area to be dusted by the exhaust port through the negative pressure. Under the action of wind, the airflow will generate vortices. The centrifugal effect of the rotation of the vortex causes the dust particles to be briefly detained and then drawn away by the inner cavity of the duct, effectively reducing or even avoiding the falling of dust, preventing the dust from spreading, and helping to improve and ensure the dust removal, especially suitable for use in situations with high cleanliness requirements.

Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a dust removal duct structure and a laser processing dust removal structure. Background Technology

[0002] Laser processing is widely used in production processes such as cutting, engraving, and drilling. During the processing, a large amount of impurities and dust are easily generated, so the dust in the processing environment needs to be treated before being discharged.

[0003] In existing technologies, a circular tube-shaped exhaust duct is typically installed at the processing location. This duct connects to external dust removal and filtration equipment, and negative pressure is maintained by the duct to draw away smoke and dust. However, existing exhaust ducts are not effective at removing smoke and dust, and there is a risk of smoke and dust falling during the extraction process, making them particularly unsuitable for industries with high cleanliness requirements. Utility Model Content

[0004] To address the aforementioned issues, this application provides a reasonably structured dust removal duct and a laser-processed dust removal structure, thereby effectively reducing or even preventing the falling of smoke and dust, preventing the dispersion of smoke and dust, and helping to improve and ensure the extraction of smoke and dust, especially suitable for use in situations with high cleanliness requirements.

[0005] The technical solution adopted in this utility model is as follows: A dust removal duct structure includes a housing, which includes a first side plate and a second side plate arranged on both sides, and a spiral shell portion connecting the first side plate and the second side plate. The first side plate is fitted with dustproof laser glass, and the middle of the second side plate forms an exhaust port that runs through the inside and outside, with the exhaust port facing the object or area to be dusted. The spiral shell portion extends along the spiral direction and together with the first side plate and the second side plate forms a duct opening, which is connected to external dust removal equipment via a duct section.

[0006] As a further improvement to the above technical solution: The spiral shell includes a logarithmic spiral section, the outer end of which extends tangentially to form a straight section; the inner end of the logarithmic spiral section bends and extends, together with the straight section, side plate one, and side plate two to form a circular opening.

[0007] The exhaust vent has a circular structure and occupies more than half of the area of ​​the side panel.

[0008] The dustproof laser glass can be detachably and sealedly installed on the outer side of the side panel, or the dustproof laser glass can be fixedly embedded in the side panel.

[0009] It also includes pressing components, which include pressing strips and pressing plates, both of which are annular structures. A fitting hole is opened on the side plate, and the pressing strip and pressing plate are sequentially attached to the outer wall of the side plate along the circumference of the fitting hole. The inner diameter of the pressing strip is larger than the inner diameter of the pressing plate and the diameter of the fitting hole. The outer diameter of the dustproof laser glass is adapted to the inner diameter of the pressing strip. The outer diameter of the dustproof laser glass is larger than the inner diameter of the pressing plate and the diameter of the fitting hole. The dustproof laser glass covering the fitting hole is located inside the pressing strip between the side plate and the pressing plate.

[0010] The dustproof laser glass is press-fitted with sealing rings along its edge circumferentially and between the outer wall of the side plate and the pressure plate; a stud extends outward from the outer wall of the side plate surrounding the mounting hole, and a locking nut is locked after the stud passes through the press-fitting part.

[0011] The two edges of the side plate extend outward to form two or more lugs, and the external locking member installs the dust removal air duct onto the object through the lugs.

[0012] A laser processing dust removal structure includes the dust removal duct structure described above, and further includes a laser installed outside the dustproof laser glass, with the laser emission end facing the dustproof laser glass. The laser emitted by the laser passes through the dustproof laser glass and processes the object located outside the exhaust port.

[0013] As a further improvement to the above technical solution: It also includes a hollow housing, with the side plate of the dust removal duct structure attached to the inner wall of the housing, and through holes on the wall of the housing that are directly opposite the exhaust port.

[0014] The two edges of the side plate extend outward to form two or more lugs, and the lugs are provided with slots. The inner wall of the accommodating box extends inward to form a protruding post passing through the slot. It also includes a locking member fitted to the end of the protruding post, which fixes the lugs toward the accommodating box.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This utility model, through the setting of the spiral shell, combined with the pipe opening and the exhaust port, can draw dust from the object or area to be cleaned by maintaining negative pressure. Under the action of wind, the airflow will generate vortex. The centrifugal effect of the vortex causes the dust particles to be drawn away from the inner cavity of the air duct after a short stay, effectively reducing or even avoiding the falling of dust and preventing the dust from spreading. It helps to improve and ensure the dust is removed, and is especially suitable for use in situations with high cleanliness requirements. This utility model also has the following advantages: The laser emission end and the object to be processed are located on both sides of the dust removal duct structure. The laser passes through the dustproof laser glass and the dust removal duct structure to process the object. At the same time, the dust removal duct structure, together with external dust removal equipment, removes dust. The overall layout is not only compact and ingenious with a small footprint, but also effectively ensures the dust removal effect during laser processing, thus helping to guarantee the quality of laser processing.

[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0026] like Figure 1 and Figure 2As shown, a dust removal duct structure of this embodiment includes a housing 1. The housing 1 includes a first side plate 12 and a second side plate 13 arranged on both sides, and a spiral shell portion 11 connecting the first side plate 12 and the second side plate 13. A dustproof laser glass 3 is embedded on the first side plate 12. The middle part of the second side plate 13 forms an exhaust port 16 that runs through the inside and outside. The exhaust port 16 is directly facing the object or area to be dusted. The spiral shell portion 11 extends along the spiral direction and together with the first side plate 12 and the second side plate 13 forms a pipe opening 15. The pipe opening 15 is connected to the external dust removal equipment through the pipe section 6.

[0027] In this embodiment, by setting the spiral shell 11, combined with the pipe 15 and the exhaust port 16, the exhaust port 16 can draw dust from the object or area to be cleaned by maintaining negative pressure. Under the action of wind, the airflow will generate vortex. The centrifugal effect of the vortex rotation causes the dust particles to be drawn away from the inner cavity of the air duct after a short stay, effectively reducing or even avoiding the falling of dust and preventing the spread of dust.

[0028] The spiral shell 11 includes a logarithmic spiral portion 111, the outer end of which extends tangentially to form a straight portion 112; the inner end of the logarithmic spiral portion 111 bends and extends, together with the straight portion 112, side plate one 12, and side plate two 13, to form a tube opening 15 with a circular structure.

[0029] A logarithmic spiral, also known as a logarithmic spiral or equiangular spiral, is a curve in a polar coordinate system in which the polar radius and polar angle have an exponential relationship. Its core characteristic is that the angle between the tangent at any point on the curve and the radius remains constant. It is widely used in nature and engineering fields. For example, the shell of a snail in nature is in the shape of a logarithmic spiral.

[0030] In this embodiment, by setting the logarithmic spiral part 111 and extending it to form a pipe opening 15 at its outer end, it effectively matches the vortex formed by the airflow under the action of wind. It can effectively and completely draw away the smoke and dust along the vortex, thus cleverly utilizing the attraction between fluid molecules to achieve reliable and dead-angle smoke and dust suction, ensuring the smoke and dust removal effect.

[0031] In this embodiment, the logarithmic spiral portion 111 can be configured as a left-handed or right-handed structure according to actual needs, and a nozzle 15 can be formed at its outer end extension.

[0032] In this embodiment, the circular opening 15 facilitates pipe connection with the pipe section 6 and external dust removal equipment.

[0033] The exhaust vent 16 has a circular structure and occupies more than half of the area of ​​the side plate 13; thus, the exhaust vent 16 with a large opening area can effectively ensure the intake of smoke and dust from the object to be dusted or the area to be dusted.

[0034] In one embodiment, the dustproof laser glass 3 is detachably and sealed to the outer side of the side plate 12 to facilitate maintenance of the dust removal duct structure and replacement of the dustproof laser glass 3.

[0035] In another embodiment, the dustproof laser glass 3 is fixedly embedded in the side plate 12.

[0036] It also includes press-fit component 4, such as Figure 3 and Figure 4 As shown, the pressing component 4 includes a pressing strip 42 and a pressing plate 41, both of which are annular structures. A fitting hole is provided on the side plate 12. The pressing strip 42 and the pressing plate 41 are sequentially attached to the outer wall of the side plate 12 along the circumference of the fitting hole. The inner diameter of the pressing strip 42 is larger than the inner diameter of the pressing plate 41 and the diameter of the fitting hole. The outer diameter of the dustproof laser glass 3 is adapted to the inner diameter of the pressing strip 42. The outer diameter of the dustproof laser glass 3 is larger than the inner diameter of the pressing plate 41 and the diameter of the fitting hole. The dustproof laser glass 3 covering the fitting hole is located inside the pressing strip 42 between the side plate 12 and the pressing plate 41.

[0037] In this embodiment, the pressure strip 42 and pressure plate 41 on the outer wall of the side plate 12 are fitted together to form a reliable installation space for the dustproof laser glass 3, so that the dustproof laser glass 3 can be effectively fitted and covered at the mounting hole of the side plate 12.

[0038] A sealing ring 9 is press-fitted between the dustproof laser glass 3 and the outer wall of the side plate 12 and the pressure plate 41 along the circumferential edge, so as to achieve effective, reliable and sealed installation of the dustproof laser glass 3 on the outer side of the side plate 12. A stud 17 is formed by extending outward from the outer wall of the side plate 12 around the mounting hole. After the stud 17 passes through the press-fitting part 4, a locking nut 5 is locked in place, which makes the installation operation convenient.

[0039] The edge of the second side plate 13 extends outward to form two or more lugs 14. The external locking member 2 installs the dust removal duct onto the object through the lugs 14. Thus, the dust removal duct structure is relatively fixed relative to the object through the lugs 14 and the external locking member 2, which helps to ensure the dust removal effect.

[0040] In this embodiment, the locking component 2 can be a conventional bolt or other fastener, or it can be a standard product such as a quick-release handle that is easy to operate, so as to achieve quick assembly and disassembly between the lug 14 and the object.

[0041] This embodiment also proposes a dust removal structure for laser processing, such as... Figure 5 and Figure 6 As shown, the dust removal duct structure includes any of the above-mentioned features, and also includes a laser 7 installed outside the dustproof laser glass 3. The light-emitting end of the laser 7 faces the dustproof laser glass 3. The laser emitted by the laser 7 passes through the dustproof laser glass 3 and processes the object located outside the exhaust port 16.

[0042] In this embodiment, the laser 7 output end and the object to be processed are located on both sides of the dust removal duct structure. The laser passes through the dustproof laser glass 3 and the dust removal duct structure to process the object. At the same time, the dust removal duct structure, combined with external dust removal equipment, removes dust. The overall layout is not only compact and ingenious with a small volume, but also effectively ensures the dust removal effect during laser processing, thus helping to ensure the effect of laser processing.

[0043] It also includes a hollow housing 8, with a side plate 13 of the dust removal duct structure attached to the inner wall of the housing 8, and a through hole 81 on the wall of the housing 8 that is directly opposite the exhaust port 16.

[0044] In actual use, the object to be processed is located outside the through hole 81 of the housing 8, and the exhaust port 16 of the dust removal duct structure is located inside the through hole 81 and faces the outer processing area to remove dust.

[0045] In this embodiment, the housing 8 not only enables the fixed installation of the dust removal duct structure, but also allows the laser 7 and the dust removal duct structure to be arranged together inside the housing 8, serving as a dustproof cover and isolating the product production area from other institutions to ensure relative cleanliness of the product production area during processing.

[0046] In this embodiment, the housing 8 also serves to protect the laser 7, thereby increasing its service life.

[0047] like Figure 7 and Figure 8 As shown, the edge of the second side plate 13 extends outward to form two or more lugs 14, and the lugs 14 are provided with slots. The inner wall of the accommodating box 8 extends inward to form a protruding post 82 passing through the slot. It also includes a locking member 2 fitted to the end of the protruding post 82, and the locking member 2 fixes the lugs 14 toward the accommodating box 8.

[0048] In this embodiment, the locking component 2 can be an existing standard product, such as a quick-release handle, or other conventional products. After the protrusion 82 passes through the groove of the lug 14, the locking component 2 can quickly fix it, which is convenient for disassembly and cleaning.

[0049] This invention effectively reduces or even avoids the falling of smoke and dust, prevents the dispersion of smoke and dust, and helps to improve and ensure the removal of smoke and dust, especially suitable for use in situations where high cleanliness is required.

[0050] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
