Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, and more specifically, to a slag removal device for laser cutting machines. Background Technology

[0002] A laser cutting machine is a device that uses a high-energy laser beam to cut materials. It mainly consists of a laser, an optical system, and a control system. The high-energy laser beam generated by the laser irradiates the surface of the material, causing it to melt, vaporize, or evaporate under the laser's influence. Simultaneously, the laser cutting machine is equipped with a coaxial high-speed airflow system to blow away the molten or vaporized material, thus achieving precise and rapid cutting. The working principle of a laser cutting machine can be simply understood as a "thermal cutting process." A high-power-density laser beam is focused on the workpiece surface, instantly heating the material to an extremely high temperature, causing it to melt, vaporize, or reach its ignition point. At the same time, a high-speed airflow coaxial with the beam blows away the molten material, thus achieving cutting. The key component of the laser cutting machine—the laser cutting head—uses a lens to focus the laser into a very small spot with extremely high power density. When the spot is adjusted to the workpiece surface, cutting can begin.

[0003] During the operation of a laser cutting machine, the laser grating, as a crucial component supporting the workpiece being cut and guiding the laser beam, is prone to accumulating molten slag and debris generated during cutting. These impurities not only affect the transmission quality of the laser beam but may also damage the laser grating, thereby impacting cutting accuracy and efficiency. Existing slag removal methods mostly employ manual cleaning or slag removal machines with a single saw blade, which are inefficient and struggle to guarantee thorough and uniform slag removal. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a slag removal device for laser cutting machines, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A slag removal device for a laser cutting machine includes a laser cutting machine grating and a machine body. Multiple sets of laser cutting machine gratings are evenly distributed inside the machine body. A translation mechanism is spaced apart on the upper side of the laser cutting machine grating. A slag removal mechanism is fixedly connected to the lower side of the translation mechanism. Both ends of the translation mechanism are connected to the machine body through a traveling mechanism.

[0007] Furthermore, the translation mechanism includes a crossbeam plate, a drive motor, a lead screw, a connecting plate, a nut seat, and a fixed seat. The crossbeam plate is arranged parallel to the upper side of the laser cutting machine's sword grid. Fixed seats are fixedly provided at both ends of the bottom of the crossbeam plate. A lead screw is rotatably connected inside the fixed seat. The left end of the lead screw is fixedly connected to the output end of the drive motor. A nut seat is rotatably connected to the lead screw. A connecting plate is fixedly provided on the lower side of the nut seat.

[0008] Furthermore, guide rods are fixed on both the front and rear sides of the lead screw, and sliders are installed on the connection corresponding to the guide rods, with the sliders slidably connected to the guide rods.

[0009] Furthermore, the slag removal mechanism includes a top plate, connecting rods, a bottom plate, slag removal saw blades, a servo motor, saw grooves, a driving bevel gear, a driven bevel gear, and a drive shaft. The top plate is fixedly connected to the bottom of the connecting plate. The bottom plate is fixedly connected to the bottom plate via multiple sets of connecting rods. The drive shaft is mounted on the bottom plate via a shaft seat. Multiple sets of slag removal saw blades are evenly mounted on the drive shaft. The bottom plate has saw grooves that match the slag removal saw blades at the corresponding locations. The slag removal saw blades pass through the saw grooves. A driven bevel gear is mounted at the rear end of the drive shaft. A driving bevel gear is meshed with the driven bevel gear. The driving bevel gear is mounted on the output end of the servo motor.

[0010] Furthermore, the lateral width of the base plate is greater than the diameter of the slag removal saw blade.

[0011] Furthermore, the walking mechanism includes a hydraulic cylinder, a support plate, a drive motor, and walking wheels. The support plate is disposed on the lower side of the fixed seat, and a hydraulic cylinder is installed on the upper side of the support plate. The upper end of the hydraulic cylinder is fixedly connected to the fixed seat. Two sets of walking wheels are provided on the lower side of the support plate, and the walking wheels are driven by the drive motor.

[0012] Furthermore, a guide rail is longitudinally and parallelly installed on the upper surface of the machine body, and the traveling wheel is inserted into the guide rail and rolled in connection with it.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model can quickly remove slag from the laser cutting machine's slag grid through a slag removal mechanism. At the same time, multiple sets of slag removal saw blades can simultaneously remove slag from multiple rows of slag grids. Combined with a translation mechanism and a walking component, continuous and all-round slag removal from the slag grid is achieved, which greatly improves the slag removal efficiency and effect.

[0015] 2. This utility model uses a translation mechanism to drive the slag removal mechanism to move laterally above the blade grid, achieving comprehensive slag removal. When the drive motor starts, it drives the lead screw to rotate. The rotational motion of the lead screw is converted into linear motion through the nut seat, causing the nut seat to move along the axial direction of the lead screw. The connecting plate on the lower side of the nut seat moves accordingly, driving the slag removal mechanism to move laterally above the laser cutting machine's blade grid. By controlling the rotation direction and speed of the drive motor, precise translation and positioning of the slag removal mechanism can be achieved.

[0016] 3. In this utility model, guide rods are fixed on both the front and rear sides of the lead screw. The main function of the guide rods is to provide guidance and support, ensuring that the connecting plate moves along a predetermined path during translation and preventing deviation or tilting. A slider is installed on the connecting plate at a position corresponding to the guide rod. The slider is slidably connected to the guide rod and moves along the surface of the guide rod to reduce frictional resistance and wear during movement, thus achieving smooth sliding of the connecting plate. When the drive motor starts and drives the lead screw to rotate, the nut seat moves along the axial direction of the lead screw. At the same time, the slider on the connecting plate slides smoothly along the surface of the guide rod, providing additional guidance and support for the connecting plate. Through the combined action of the guide rod and the slider, the stability and accuracy of the connecting plate during translation are ensured, thereby ensuring that the slag removal mechanism can move according to the predetermined path and speed.

[0017] 4. In this utility model, the horizontal width of the base plate is greater than the diameter of the slag-removing saw blade. This design makes the slag-removing saw blade more stable during rotation, reducing deviation or tilting caused by vibration or external forces. Simultaneously, the wide base plate effectively shields the sides of the slag-removing saw blade, reducing the risk of direct contact between the operator and the rotating saw blade during use. Furthermore, the wide base plate effectively shields the slag-removing saw blade, preventing debris from flying everywhere and causing personal injury.

[0018] 5. This utility model utilizes a translation mechanism to enable the slag removal mechanism to move longitudinally along the machine body, achieving slag removal at different positions of the blade grid. When the height of the equipment needs to be adjusted, the hydraulic system supplies pressurized oil to the hydraulic cylinder, pushing the piston rod of the hydraulic cylinder to move up and down, thereby driving the translation mechanism to rise and fall. When the slag removal mechanism needs to be moved, the drive motor starts, driving the traveling wheels to rotate, thus moving the slag removal mechanism forward or backward. By controlling the rotation direction and speed of the drive motor, precise movement and positioning of the equipment can be achieved. Attached Figure Description

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0028] Example:

[0029] like Figures 1 to 7As shown, a slag removal device for a laser cutting machine includes a laser cutting machine scabbard 1 and a machine body 2. Multiple sets of laser cutting machine scabbards 1 are evenly distributed inside the machine body 2. During laser cutting, the scabbards guide and support the cutting process. Translation mechanisms 5 are spaced apart on the upper side of the laser cutting machine scabbard 1, responsible for driving the slag removal mechanism 4 to move laterally above the scabbard, achieving comprehensive slag removal. The slag removal mechanism 4 is fixedly connected to the lower side of the translation mechanism 5, used for rapid slag removal from the scabbard. A rotating slag removal saw blade 44 cleans the slag on the scabbard. Both ends of the translation mechanism 5 are connected to the machine body 2 via a traveling mechanism 3. The translation mechanism 5 enables the slag removal mechanism 4 to move longitudinally along the machine body 2, achieving slag removal processing for scabbards at different positions. This design solves the problem that existing laser cutting machine scabbard 1 slag removal methods mostly rely on manual cleaning or slag removal machines with a single saw blade, resulting in low efficiency and difficulty in ensuring thorough and uniform slag removal.

[0030] In this embodiment, the translation mechanism 5 includes a crossbeam plate 51, a drive motor 52, a lead screw 53, a connecting plate 56, a nut seat 57, and a fixed seat 58. The crossbeam plate 51 is arranged parallel to the upper side of the laser cutting machine's sword grid 1, providing a stable platform for fixing other components. Fixed seats 58 are fixedly installed at both ends of the bottom of the crossbeam plate 51 to fix the lead screw 53 to the crossbeam plate 51 and provide rotational support for the lead screw 53. The lead screw 53 is rotatably connected inside the fixed seat 58. The left end of the lead screw 53 is fixedly connected to the output end of the drive motor 52. The nut seat 57 is rotatably connected to the lead screw 53, and the nut seat 57 cooperates with the lead screw 53, achieving linear motion through a threaded connection. A connecting plate 56 is fixedly installed on the lower side of the nut seat 57 to connect the nut seat 57 and the slag removal mechanism 4, transmitting the translational motion to the slag removal mechanism 4 to drive its movement. The translation mechanism 5 is responsible for driving the slag removal mechanism 4 to move laterally above the sword grid, achieving comprehensive slag removal. When the drive motor 52 starts, it drives the lead screw 53 to rotate. The rotational motion of the lead screw 53 is converted into linear motion through the nut seat 57, causing the nut seat 57 to move along the axial direction of the lead screw 53. The connecting plate 56 on the lower side of the nut seat 57 moves accordingly, driving the slag removal mechanism 4 to move laterally above the laser cutting machine's sword grid 1. By controlling the rotational direction and speed of the drive motor 52, the precise translation and positioning of the slag removal mechanism 4 can be achieved.

[0031] In this embodiment, guide rods 54 are fixed on both the front and rear sides of the lead screw 53. The main function of the guide rods 54 is to provide guidance and support, ensuring that the connecting plate 56 moves along a predetermined path during translation and preventing deviation or tilting. A slider 55 is installed on the connection corresponding to the guide rod 54. The slider 55 is slidably connected to the guide rod 54 and moves along the surface of the guide rod 54 to reduce frictional resistance and wear during movement, thus achieving smooth sliding of the connecting plate 56. When the drive motor 52 starts and drives the lead screw 53 to rotate, the nut seat 57 moves axially along the lead screw 53. At the same time, the slider 55 on the connecting plate 56 slides smoothly along the surface of the guide rod 54, providing additional guidance and support for the connecting plate 56. Through the combined action of the guide rod 54 and the slider 55, the stability and accuracy of the connecting plate 56 during translation are ensured, thereby ensuring that the slag removal mechanism 4 can move according to the predetermined path and speed.

[0032] In this embodiment, the slag removal mechanism 4 includes a top plate 41, connecting rods 42, a bottom plate 43, slag removal saw blades 44, a servo motor 45, saw grooves 46, a driving bevel gear 47, a driven bevel gear 48, and a drive shaft 49. The top plate 41 is fixedly connected to the bottom of the connecting plate 56. The bottom plate 43 is fixedly connected to the bottom side of the top plate 41 through multiple sets of connecting rods 42. The drive shaft 49 is mounted on the bottom side of the bottom plate 43 through a bearing seat. Multiple sets of slag removal saw blades 44 are evenly mounted on the drive shaft 49. The bottom plate 43 has saw grooves 46 that are adapted to the slag removal saw blades 44 at the corresponding positions. The slag removal saw blades 44 pass through the saw grooves 46. The driven bevel gear 48 is mounted at the rear end of the drive shaft 49. The driving bevel gear 47 is meshed and connected to the driven bevel gear 48. The driving bevel gear 47 is mounted on the output end of the servo motor 45. The slag removal mechanism 4 is used for rapid slag removal from the blade grid. A rotating slag removal saw blade 44 cleans the slag on the blade grid. Simultaneously, multiple sets of slag removal saw blades 44 process multiple rows of blade grids, greatly improving slag removal efficiency and effectiveness. When the servo motor 45 starts, it drives the active bevel gear 47 to rotate. The active bevel gear 47 meshes with the driven bevel gear 48, driving the drive shaft 49 to rotate. The slag removal saw blades 44 on the drive shaft 49 rotate accordingly. The rotating slag removal saw blades 44 contact the slag on the laser cutting machine's blade grid 1, cutting it off and achieving rapid slag removal.

[0033] In this embodiment, the lateral width of the base plate 43 is greater than the diameter of the slag-removing saw blade 44. This design makes the slag-removing saw blade 44 more stable during rotation, reducing deviation or tilting caused by vibration or external forces. Simultaneously, the wide base plate 43 effectively shields the sides of the slag-removing saw blade 44, reducing the risk of direct contact between the operator and the rotating saw blade during use. Furthermore, the wide base plate 43 effectively shields the slag-removing saw blade 44, preventing debris from flying everywhere and causing personal injury.

[0034] In this embodiment, the walking mechanism 3 includes a hydraulic cylinder 32, a support plate 33, a drive motor 34, and walking wheels 35. The support plate 33 is located below the fixed base 58, and the hydraulic cylinder 32 is mounted on the upper side of the support plate 33. This hydraulic cylinder 32 is responsible for adjusting the height of the translation mechanism 5, thereby adjusting the depth to which the slag-removing saw blade 44 extends into the laser cutting machine's blade grid 1. The upper end of the hydraulic cylinder 32 is fixedly connected to the fixed base 58. Two sets of walking wheels 35 are located on the lower side of the support plate 33, and the walking wheels 35 are driven by the drive motor 34. The translation mechanism 5 enables the slag removal mechanism 4 to move longitudinally along the machine body 2, achieving slag removal processing at different positions of the blade grid. When the height of the equipment needs to be adjusted, the hydraulic system provides pressurized oil to the hydraulic cylinder 32, pushing the piston rod of the hydraulic cylinder 32 up and down, thereby driving the translation mechanism 5 to rise and fall. When the slag removal mechanism 4 needs to be moved, the drive motor 34 starts, driving the walking wheels 35 to rotate, thereby moving the slag removal mechanism 4 forward or backward. By controlling the rotation direction and speed of the drive motor 34, precise movement and positioning of the equipment can be achieved.

[0035] In this embodiment, a guide rail 31 is longitudinally and parallelly mounted on the upper surface of the machine body 2, and the traveling wheel 35 is inserted into the guide rail 31 and rolled in connection with it. The guide rail 31 provides support and guidance for the traveling wheel 35, which can limit the direction of movement of the traveling wheel 35 and ensure that the traveling wheel 35 moves longitudinally along the upper surface of the machine body 2, thereby realizing the precise movement of the slag removal mechanism 4.

[0036] The working principle of a slag removal device for a laser cutting machine:

[0037] The device is installed on a laser cutting machine, and multiple sets of laser cutting machine sword grids 1 are evenly distributed inside the machine body 2.

[0038] The translation mechanism 5 is located on the upper side of the slag grate and is responsible for driving the slag removal mechanism 4 to move laterally above the slag grate. The traveling mechanism 3 connects the translation mechanism 5 to the machine body 2, enabling the slag removal mechanism 4 to move longitudinally along the machine body 2. The guide rail 31 is installed on the upper surface of the machine body 2, and the traveling wheel 35 is inserted into the guide rail 31 and rolled to it, providing support and guidance.

[0039] In actual use, firstly, the drive motor 34 on the walking mechanism 3 drives the walking wheel 35 to rotate, causing the slag removal mechanism 4 to move forward or backward along the guide rail 31, so that it moves to the position on the laser cutting machine's sword grid 1 where slag needs to be removed; then, the hydraulic system supplies pressurized oil to the hydraulic cylinder 32, and the hydraulic system adjusts the piston rod of the hydraulic cylinder 32 to move up and down, thereby adjusting the height of the translation mechanism 5 and the depth of the slag removal saw blade 44 extending into the sword grid, so that the slag removal saw blade 44 of the slag removal mechanism 4 is engaged in the laser cutting machine's sword grid 1; then, the servo motor 45 starts, driving the active bevel gear 47 to rotate, and the active bevel gear 47 meshes with the driven bevel gear 48 to drive the drive shaft 49 to rotate, and the slag removal saw blade 44 on the drive shaft 49 rotates accordingly, contacting the slag on the laser cutting machine's sword grid 1 and removing it. Multiple sets of slag-removing saw blades 44 simultaneously remove slag from multiple rows of blade grids, improving slag removal efficiency and effect. At the same time, the drive motor 52 is started, driving the lead screw 53 to rotate. The rotational motion of the lead screw 53 is converted into linear motion through the nut seat 57, and the nut seat 57 moves along the axial direction of the lead screw 53. The connecting plate 56 on the lower side of the nut seat 57 moves accordingly, driving the slag removal mechanism 4 to move laterally above the laser cutting machine blade grid 1, realizing continuous slag removal on the laser cutting machine blade grid 1.

[0040] In summary, this slag removal device for laser cutting machines achieves rapid, comprehensive, and precise slag removal of the laser cutting machine's blade grid 1 through the coordinated operation of the translation mechanism 5, the slag removal mechanism 4, and the traveling mechanism 3. Its operation is simple and convenient, greatly improving slag removal efficiency and effectiveness, and ensuring the normal operation and production efficiency of the laser cutting machine.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
