Description

Technical Field

[0001] This invention relates to the field of slag removal device technology, specifically to a slag removal device and method for a laser cutting machine rack. Background Technology

[0002] Laser cutting machines have several support racks on their worktables to support the steel plates and other parts being cut during the cutting process. During use, slag accumulates on these racks. For laser cutting machines with slag removal capabilities, this is achieved through a built-in slag removal mechanism. For example, Chinese patent document CN 117921205B discloses a laser cutting machine that not only performs dust extraction in the area surrounding the laser cutting head during cutting, but also removes slag adhering to the support racks. Simultaneously, it separates and recycles dust, waste, and slag generated during cutting and slag removal, thus ensuring a good production environment, improving cutting accuracy, and facilitating subsequent waste recycling.

[0003] However, existing laser cutting machines without slag removal functions tend to accumulate slag on the support racks during use. If the slag is not cleaned in time, excessive accumulation can render the support racks unusable, requiring replacement with new laser cutting machine racks, which is costly and reduces work efficiency. Manually removing slag with a scraper is inconvenient, time-consuming, and labor-intensive. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of waste residue accumulation on the racks of existing laser cutting machines without slag removal functions, leading to rack scrapping, high costs, and labor-intensive and inefficient manual slag removal. The invention provides a slag removal device and method for laser cutting machine racks, which can easily and quickly remove waste residue generated during the laser cutting process that adheres to the supporting racks. The device is easy to move without jamming, has a simple structure, and is applicable to various types of racks, making it widely applicable and highly adaptable.

[0005] The technical solution adopted by this invention to achieve its first objective is: a slag removal device for a laser cutting machine rack, comprising a movable base, a support fixed on the movable base, and at least one set of slag removal mechanisms hinged to the support. The slag removal mechanism includes a pressure rod and a slag removal cleaning component connected to the pressure rod and driven to rotate by the pressure rod. A slag removal cleaning slot is provided on the slag removal cleaning component, and a corresponding movable slot for the slag removal cleaning component is provided on the movable base. This laser cutting machine rack slag removal device, by providing a movable base that can be placed on and moved on a supporting rack, and a support on the movable base, hinges a slag removal mechanism. The slag removal mechanism includes a pressure rod and a slag removal cleaning component. The pressure rod drives the slag removal cleaning component to be positioned around the support in a high-pressure lever structure, thereby allowing the slag removal cleaning slot on the slag removal cleaning component to be inserted into the supporting rack to be slag removed, and rotating it from bottom to top to remove the accumulated slag from the supporting rack. To facilitate the insertion of the slag removal and cleaning components and the supporting rack, a movable slot for the slag removal and cleaning components is provided on the movable base. This laser cutting machine rack slag removal device is specifically designed for slag removal on existing laser cutting machine supporting racks that do not have a slag removal mechanism. It can operate individually on the supporting rack to be slag removed, quickly removing accumulated slag. After cleaning, the entire laser cutting machine rack slag removal device can be removed. It is easy to operate, and the device has a simple structure. By cooperating with the rack through the slag removal and cleaning slot on the slag removal component, lever-type slag removal can be achieved through the pressure rod. It is applicable to various rack slag removal applications, has wide applicability, strong adaptability, and low manufacturing cost.

[0006] Preferably, the slag removal and cleaning component is equipped with a rotating shaft, which is rotatably connected to the support base via a bearing. The pressure rod is coaxial with the slag removal and cleaning component and perpendicular to the rotating shaft, forming a lever structure. The pressure rod rotates around the rotating shaft as the rotation center along the support base, driving the slag removal and cleaning component to rotate and remove slag. To enable the pressure rod to drive the slag removal and cleaning component to achieve lever-type slag removal operation, a rotating shaft is directly installed on the slag removal and cleaning component. The rotating shaft is rotatably connected to the support base via a bearing. Using the rotating shaft as a fulcrum, the slag removal and cleaning groove is blocked by the accumulated slag on the support rack, which becomes the compression point, ultimately forming a lever with a strong arm. This allows the accumulated slag to be easily removed from the support rack of the laser cutting machine along both sides of the support rack.

[0007] Preferably, the slag removal and cleaning component has an overall U-shaped trough structure, including an integrally formed cleaning component trough bottom, end trough opening, two trough side walls, and a trough connecting wall opposite to the end trough opening. The slag removal and cleaning slot is opened on the cleaning component trough bottom and extends from the end trough opening towards the trough connecting wall.

[0008] Preferably, the groove walls on both sides of the slag removal and cleaning slot are configured with a scraper blade structure. To facilitate the removal of waste slag accumulated on the supporting rack, the groove walls on both sides of the slag removal and cleaning slot can be configured with a scraper blade structure.

[0009] Preferably, a guide member is provided on the inner side of the tank connecting wall along the same axis as the slag removal and cleaning slot, and the guide member is provided with an inclined guide surface. The guide member serves two purposes: firstly, it allows the waste slag to move towards the pressure rod end during the removal process, avoiding the slag removal and cleaning slot, facilitating subsequent continuous slag removal; secondly, it enhances the overall strength of the slag removal and cleaning component.

[0010] Preferably, a guide assembly is provided on the lower plate of the movable base; the guide assembly includes a drive shaft and a guide wheel rotatably mounted on the drive shaft; the guide wheel has meshing teeth recessed on it. The guide assembly on the lower plate of the movable base facilitates its movement during the slag removal process. Preferably, the guide assembly can be a guide wheel, whose meshing teeth engage with the support rack on the laser cutting machine. During the slag removal process driven by the pressure rod and the slag removal components, the movable base moves. The scraping force generated by the pressure rod and the slag removal components pressing against the slag accumulation points on the support rack during slag removal is transmitted to the guide wheel through the pressure rod and the rotating shaft, thus creating a meshing transmission between the guide wheel and the support rack. Alternatively, when meshing with the support rack is not required, the guide wheel can be used as a smooth wheel, with the gearless surface on its outer side forming a rolling wheel, which can also drive the movement of the movable base.

[0011] Preferably, the movable base has an embedding groove, and the support base has a mounting groove corresponding to the embedding groove. The embedding groove and mounting groove are provided to facilitate the installation of the guide wheel.

[0012] As another preferred embodiment, a guide assembly is provided on the lower surface of the movable base; the guide assembly is a drive rack provided on the lower surface of the base plate. Alternatively, a drive rack can also be provided on the lower surface of the movable base, which can also achieve meshing motion with a supporting rack.

[0013] Preferably, a toothed groove is formed on the lower plate of the movable base, and the drive rack is integrally set inside the toothed groove.

[0014] Preferably, a guide portion is provided on the movable base along the direction of the slag removal and cleaning slot opening; the guide portion is set at an angle of 45° to 70° with the horizontal plane of the movable base. The guide portion is provided to prevent the movable base from getting stuck during the slag removal process.

[0015] The technical solution adopted by the present invention to achieve its second objective is: a slag removal method, which utilizes the aforementioned laser cutting machine rack slag removal device, comprising the following steps: S1: Place the laser cutting machine rack slag removal device on the support rack and insert the slag removal cleaning slot into the support rack to be slag removed; S2: Drive the pressure rod, using the rotating shaft 7 as the fulcrum, to make the slag removal and cleaning slot 55 rotate upward, using the waste slag as the squeeze point, to perform a large arm lever slag removal, removing the waste slag from the support rack and upward along the surface of the support rack.

[0016] Preferably, in step 1, the slag removal device of the laser cutting machine rack is placed on the supporting rack. While the pressure rod is pressed down, the guide component drives the moving base to move along the length of the supporting rack to remove slag from the entire supporting rack.

[0017] The guide wheel or drive rack can mesh with the support racks on both sides of the support rack to be descaled. When the pressure rod presses down, it meshes with the support rack, driving the moving base to move along the length of the support rack, thus performing descaling operation on the entire support rack to be descaled. Alternatively, the guide wheel can be used as a rolling wheel to drive the moving base, or the moving base can be moved by directly forming a moving surface on its lower plate.

[0018] Compared with existing technologies, the advantages of this invention are: This laser cutting machine rack slag removal device is made using levers, making it simple to manufacture. It allows for individual operation of the supporting rack to be slag removed, quickly removing accumulated slag. After cleaning, the entire laser cutting machine rack slag removal device can be removed. It is easy to operate, applicable to various rack slag removal methods, and has wide applicability and strong adaptability. The pressure rod transmits the slag removal reverse force, driving the moving base through the guide assembly, eliminating the need for an additional drive device and reducing manufacturing costs. The guide part of the moving base ensures smooth slag removal movement and prevents jamming. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Components not specifically described in the present invention are all existing components or general components.

[0034] Example 1:

[0035] In Figure 1, Figure 2 , Figure 3 , Figure 4 , Figure 5 In the illustrated embodiment, a slag removal device for a laser cutting machine rack includes a movable base 1, a support base 2 fixed on the movable base 1, and a slag removal mechanism 3 hinged to the support base 2. The slag removal mechanism 3 includes a pressure rod 4 and a slag removal cleaning component 5 connected to the pressure rod 4 and driven to rotate by the pressure rod. A slag removal cleaning slot 55 is provided on the slag removal cleaning component 5, and a slag removal cleaning component movable slot 11 is provided on the movable base corresponding to the slag removal cleaning component 5. The slag removal mechanism can be provided in one set, or two or more sets, depending on actual needs.

[0036] The slag removal and cleaning component 5 is equipped with a rotating shaft 7, which is rotatably connected to the support base 2 via a bearing 8. The pressure rod 4 is coaxially arranged with the slag removal and cleaning component and perpendicular to the rotating shaft 7 to form a lever structure. The rotating shaft 7 is directly mounted on the slag removal and cleaning component and is fixed as one piece. The rotating shaft is rotatably connected to the support base via a bearing, making the rotating shaft a fulcrum. The slag removal and cleaning groove is blocked by the accumulated slag on the support rack, which becomes the squeezing point, ultimately forming a lever with a strong arm. This allows the accumulated slag to be easily removed from the support rack of the laser cutting machine along both sides of the support rack.

[0037] See Figure 6 The slag removal and cleaning component 5 has an overall U-shaped trough structure, including an integrally formed cleaning component trough bottom 51, end trough opening 52, two trough side walls 53, and a trough connecting wall 54 opposite to the end trough opening 52. The slag removal and cleaning slot 55 is opened on the cleaning component trough bottom 51 and extends from the end trough opening to the trough connecting wall 54.

[0038] In another embodiment, the side walls of the slag removal and cleaning groove 55 can be configured as a scraper blade structure 58. This scraper blade structure facilitates the removal of waste slag.

[0039] A guide member 56 is provided on the inner side of the tank connecting wall 55 along the same axis as the slag removal and cleaning slot 55. An inclined guide surface 57 is provided on the guide member 56. The guide member and the inclined guide surface are provided for two purposes: firstly, to allow the waste slag to move towards the pressure rod end during the removal process, avoiding the slag removal and cleaning slot, thus facilitating subsequent continuous slag removal; and secondly, to enhance the strength of the entire slag removal and cleaning component.

[0040] A movable base guide 12 is provided on the movable base 1 along the opening direction of the slag removal and cleaning groove 55; the movable base guide 12 is set at an angle of 45~70° with the horizontal plane of the movable base, so that it can move forward without obstruction during the slag removal process. In this embodiment, the movable base guide 12 is set at an angle of 45° with the horizontal plane of the movable base.

[0041] See Figure 7 A slag removal method, which utilizes the aforementioned laser cutting machine rack slag removal device, includes the following steps: S1: Place the laser cutting machine rack slag removal device on the support rack and insert the slag removal cleaning slot 55 into the support rack to be slag removed; In this embodiment, the lower plate of the movable base 1 directly contacts and supports the support racks on both sides to be slag removed.

[0042] S2: Drive the pressure rod, using the rotating shaft 7 as a fulcrum, to rotate the slag removal and cleaning groove 55 upwards. Using the waste slag as the squeeze point, perform a large-arm lever slag removal, removing the waste slag from the support rack and upwards along its surface. Simultaneously, as the pressure rod presses downwards, it drives the movable base to move along the length of the support rack, performing slag removal on the entire support rack to be slag removed.

[0043] Example 2:

[0044] exist Figure 8 , Figure 9 In the embodiment shown, a slag removal device for a laser cutting machine rack includes a movable base 1, a support base 2 fixed on the movable base 1, and at least one set of slag removal mechanisms 3 hinged to the support base 2.

[0045] The slag removal mechanism 3 includes a pressure rod 4 and a slag removal cleaning component 5 connected to the pressure rod 4. The pressure rod 4 is connected to the slag removal cleaning component 5 via a support plate 6 and drives the slag removal cleaning component 5 to rotate. The slag removal cleaning component 5 is provided with a rotating shaft 7, which is rotatably connected to the support base 2 via a bearing 8.

[0046] The slag removal and cleaning component 5 is configured as a trough structure, comprising a trough bottom 51, an end opening 52, two side walls 53, and a connecting wall 54 at the end opposite to the end opening 52. The outer side of the connecting wall 54 is fixedly connected to the support plate 6. A slag removal and cleaning groove 55 is formed on the trough bottom 51 of the slag removal and cleaning component 5, extending inward from the end opening. The width of the slag removal and cleaning groove 55 is slightly larger than the width of the rack on the laser cutting machine, facilitating the engagement of the slag removal and cleaning groove 55 with the rack to achieve slag removal. The length of the slag removal and cleaning component is slightly larger than the height of the supporting rack, thus facilitating the removal of accumulated slag in the height direction of the supporting rack in one go. In other embodiments, the side walls of the slag removal and cleaning groove 55 can be configured as scraper blades to facilitate scraping of accumulated slag, improve efficiency, and ensure thorough removal of slag.

[0047] A guide member 56 is provided on the inner side of the tank connecting wall 55 of the slag removal and cleaning component, along the same direction and coaxial axis as the slag removal and cleaning slot 55. The guide member 56 has an inclined guide surface 57, which is positioned upwards and backwards along the bottom 51 of the cleaning component's tank. Specifically, the lower end of the inclined guide surface 57 corresponds to the tail end of the slag removal and cleaning slot 55, while the higher end of the inclined guide surface 57 faces the tank connecting wall 55 and is at the same height. The guide member 56 also serves to strengthen the overall strength of the slag removal and cleaning component.

[0048] The movable base 1 has a U-shaped movable groove 11 for the slag removal and cleaning component. This groove 11 is located inside the two support seats 2 and accommodates the slag removal and cleaning component, providing space for its movement. A guide portion 12 is provided at the end of the movable base facing the opening of the movable groove 11, allowing for smooth forward movement during the slag removal process and reducing obstruction. The guide portion 12 is set at an angle of 45° to 70° with the horizontal plane of the movable base; in this embodiment, the guide portion 12 is set at a 60° angle with the horizontal plane of the movable base.

[0049] Two support seats 2 are provided on the upper plate of the movable base 1. The support seats 2 are used to support the force of the entire slag removal process. The support seats 2 and the slag removal cleaning component 3 are rotatably connected via a rotating shaft 7. The rotating shaft 7 and the slag removal cleaning component 3 are fixedly connected, for example, by welding, and there should be no left or right movement between the rotating shaft 7 and the slag removal cleaning component 3. The rotating shaft 7 and the support seats 2 are connected by bearings 8, which promotes no wear and low resistance during long-term rotation.

[0050] A guide component 9 is detachably provided on the lower plate of the mobile base 1. The guide component 9 can be provided in one set or in two sets, one in front and one in back.

[0051] The guide assembly 9 includes a bearing housing 91, a drive shaft 92, and guide wheels 93 rotatably mounted on the drive shaft. Each set of guide wheels 93 consists of two symmetrically arranged guide wheels on the left and right sides, and the two guide wheels 93 are rotatably connected through the drive shaft and the bearing housing. Correspondingly, an opening 13 is provided on the movable base 1.

[0052] A mounting groove 21 is provided at the bottom of the support base 2. The guide wheel 93 is rotatably mounted on the drive shaft 92 and is partially inside the mounting groove. The part of the guide wheel extending out of the mounting groove can meet the requirements of meshing and transmission with the support rack.

[0053] The guide wheel 93 is provided with concave meshing drive teeth 94, which mesh with the support rack 10. In use, the meshing drive teeth 94 mesh with the support rack, thereby pushing the slag removal mechanism 3 to remove slag from the support rack to be removed by the pressure rod 4. At the same time, the meshing drive teeth 94 on the guide wheel mesh with the support racks on both sides of the support rack to be removed, moving forward, thus facilitating slag removal along the length of the support rack.

[0054] The rotating shaft 7 has axial protrusions at both ends, and the protruding parts are just positioned at the thickness of the inner ring of the bearing. The main purpose is to fix the relative position of the rotating shaft 7 and the bearing 8.

[0055] The pressure rod 4 is a solid round rod, and a support plate 6 is provided at one end of the pressure rod 4. The support plate 6 and the pressure rod 4 are welded together. The support plate 6 has 4 through holes for fastening screws to fasten and lock the support plate 6 and the slag removal and cleaning component 3.

[0056] See Figure 10 A method for removing slag using a slag removal device includes the following steps: Step 1: Place the slag removal device on the support rack of the laser cutting machine, and insert the slag removal cleaning slot 55 into one of the support racks of the laser cutting machine that needs slag removal. The meshing drive teeth 94 on the guide wheel 93 mesh with the two adjacent support racks respectively.

[0057] The driving pressure rod 4 is pressed downwards. As the pressure rod 4 presses down, the slag removal and cleaning groove 55, blocked by waste slag, becomes the point of compression through the rotating shaft 7, ultimately forming a lever with a strong arm. This easily removes the waste slag from the support rack of the laser cutting machine, moving it upwards along the surface of the rack. Simultaneously, due to the guide wheel, as the pressure rod presses down, the meshing drive gear 94 engages with the support rack, driving the moving base to move along the length of the support rack, thus facilitating slag removal from the entire support rack. During the meshing and transmission process with the support rack, the meshing drive gear 94 can also remove waste slag from the tooth grooves of the support rack.

[0058] The aforementioned laser cutting machine rack slag removal device eliminates the need for manual slag removal, offering convenient, simple, and easy-to-maintain operation with excellent slag removal results. The removed slag from the laser cutting machine rack provides better support for the steel plate placed upon it, while the laser cutting kerf offers sufficient space for new waste slag to fall off.

[0059] Example 3:

[0060] exist Figure 11 , Figure 12 In the embodiment shown, a slag removal device for a laser cutting machine rack includes a movable base 1, a support base 2 fixed on the movable base 1, and at least one set of slag removal mechanisms 3 hinged to the support base 2.

[0061] The slag removal mechanism 3 includes a pressure rod 4 and a slag removal cleaning component 5 connected to the pressure rod 4. The pressure rod 4 is connected to the slag removal cleaning component 5 via a support plate 6 and drives the slag removal cleaning component 5 to rotate. The slag removal cleaning component 5 is provided with a rotating shaft 7, which is rotatably connected to the support base 2 via a bearing 8.

[0062] The slag removal and cleaning component 5 is configured as a trough structure, comprising a trough bottom 51, an end opening 52, two side walls 53, and a connecting wall 54 at the end opposite to the end opening 52. The outer side of the connecting wall 54 is fixedly connected to the support plate 6. A slag removal and cleaning groove 55 is formed on the trough bottom 51 of the slag removal and cleaning component 5, extending inward from the end opening. The width of the slag removal and cleaning groove 55 is slightly larger than the width of the rack on the laser cutting machine, facilitating the engagement of the slag removal and cleaning groove 55 with the rack to achieve slag removal. The length of the slag removal and cleaning component is slightly larger than the height of the supporting rack, thus facilitating the removal of accumulated slag in the height direction of the supporting rack in one go. In other embodiments, the side walls of the slag removal and cleaning groove 55 can be configured as scraper blades to facilitate scraping of accumulated slag, improve efficiency, and ensure thorough removal of slag.

[0063] A guide member 56 is provided on the inner side of the tank connecting wall 55 of the slag removal and cleaning component, along the same direction and coaxial axis as the slag removal and cleaning slot 55. The guide member 56 has an inclined guide surface 57, which is positioned upwards and backwards along the bottom 51 of the cleaning component's tank. Specifically, the lower end of the inclined guide surface 57 corresponds to the tail end of the slag removal and cleaning slot 55, while the higher end of the inclined guide surface 57 faces the tank connecting wall 55 and is at the same height. The guide member 56 also serves to strengthen the overall strength of the slag removal and cleaning component.

[0064] The movable base 1 has a U-shaped movable groove 11 for the slag removal and cleaning component. This groove 11 is located inside the two support seats 2 and is used to accommodate the slag removal and cleaning component, providing space for its movement. A guide portion 12 is provided at the end of the movable base facing the opening of the movable groove 11, allowing for smooth forward movement during the slag removal process and reducing obstruction. The guide portion 12 is set at an angle of 45° to 70° with the horizontal plane of the movable base; in this embodiment, the guide portion 12 is set at a 70° angle with the horizontal plane of the movable base.

[0065] Two support seats 2 are provided on the upper plate of the movable base 1. The support seats 2 are used to support the force of the entire slag removal process. The support seats 2 and the slag removal cleaning component 3 are rotatably connected via a rotating shaft 7. The rotating shaft 7 and the slag removal cleaning component 3 are fixedly connected, for example, by welding, and there should be no left or right movement between the rotating shaft 7 and the slag removal cleaning component 3. The rotating shaft 7 and the support seats 2 are connected by bearings 8, which promotes no wear and low resistance during long-term rotation.

[0066] A guide component 9 is detachably provided on the lower plate of the mobile base 1. The guide component 9 can be provided in one set or in two sets, one in front and one in back.

[0067] The guide component 9 is a drive rack 95 disposed on the lower plate of the movable base 1; a toothed groove 14 is provided on the lower plate of the movable base 1, and the drive rack 95 is integrally disposed inside the toothed groove 14.

[0068] In use, the drive rack 95 meshes with the support rack 10, thereby pushing the slag removal mechanism 3 to remove slag from the support rack to be removed via the pressure rod 4. Simultaneously, the drive rack 95 meshes with the support racks on both sides of the support rack to be removed, moving forward to facilitate slag removal along the length of the support rack. During the drive engagement process, a very small amount of waste slag within the tooth grooves of the support rack can also be removed.

[0069] The rotating shaft 7 has axial protrusions at both ends, and the protruding parts are just positioned at the thickness of the inner ring of the bearing. The main purpose is to fix the relative position of the rotating shaft 7 and the bearing 8.

[0070] The pressure rod 4 is a solid round rod, and a support plate 6 is provided at one end of the pressure rod 4. The support plate 6 and the pressure rod 4 are welded together. The support plate 69 has 4 through holes for fastening screws to fasten and lock the support plate 6 and the slag removal and cleaning component 3.

[0071] See Figure 13 A method for removing slag using a slag removal device includes the following steps: Step 1: Place the slag removal device on the support rack of the laser cutting machine, and insert the slag removal and cleaning slot 55 into one of the support racks of the laser cutting machine that needs slag removal. The two sets of drive racks 95 mesh with the two adjacent support racks respectively.

[0072] The driving pressure rod 4 is pressed downwards. As the pressure rod 4 presses down, the slag removal and cleaning groove 55, blocked by waste slag, becomes the point of compression through the rotating shaft 7, ultimately forming a lever with a strong arm. This easily removes the waste slag from the support rack of the laser cutting machine, moving it upwards along the surface of the support rack. Simultaneously, as the pressure rod presses down, the driving rack 95 meshes with the support rack, driving the moving base to move along the length of the support rack, thus facilitating slag removal from the entire support rack. During the meshing and transmission process between the driving rack 95 and the support rack, waste slag within the tooth grooves of the support rack can also be removed.

[0073] The removed laser cutting machine support rack can better support the steel plate placed on it, while the laser cutting kerf has enough space for new waste to fall off. The aforementioned laser cutting machine rack slag removal device eliminates the need for manual slag removal, is convenient, simple, easy to maintain, and provides excellent slag removal results.

[0074] The laser cutting machine rack slag removal device in the above embodiment does not require modification of the entire laser cutting machine. It only needs to perform slag removal on a localized area of ​​the supporting rack to be slag removed, utilizing the lever principle for simplified slag removal. The movable base 1, support base 2, slag removal mechanism 3, and guide assembly are all replaceable parts, allowing for adaptation to different supporting racks and meeting the requirements of a wide range of applications. Furthermore, it facilitates flexible replacement of easily damaged parts in the future, improving its durability. A guide section is provided on the movable base to facilitate movement during the slag removal process and prevent jamming.

[0075] This laser cutting machine rack slag removal device is used to easily and quickly remove slag that adheres to the support rack during the laser cutting process. It moves without jamming, has a simple structure, is easy to operate, highly targeted, and low in cost. It solves the problems of existing laser cutting machines without a slag removal mechanism, such as slag accumulation on the support rack, high scrap rate, frequent rack replacement, and high costs. It can greatly extend the service life of the support rack.
