Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a slag removal device for a planar laser cutting machine. Background Technology

[0002] In modern industrial production, laser cutting technology is widely used for the precision processing of materials such as metals, plastics, and wood. Especially in the processing of sheet metal, laser cutting machines have become the mainstream equipment due to their high precision and efficiency. However, during the laser cutting process, a large amount of welding slag is generated at the cutting edge of the material. This is particularly true for thin-walled materials, where welding slag easily accumulates on the cutting blade. This not only affects cutting accuracy but may also lead to blade wear and damage, thus impacting the equipment's lifespan and cutting quality.

[0003] However, traditional slag removal equipment often fails to fully remove welding slag from both sides of the transverse cutting blade, resulting in slag accumulation on the blade surface and incomplete cleaning, which affects cutting quality. Moreover, the welding slag is usually removed manually by hammering the cutting blade with a small hammer, but the slag is firmly fixed to the cutting blade and is difficult to remove by hammering. This process is also time-consuming, labor-intensive, and inefficient. Utility Model Content

[0004] To address the problems mentioned above, this utility model provides a slag removal device for a planar laser cutting machine, which effectively solves the problems of poor results, time-consuming and labor-intensive, and inefficient manual slag cleaning.

[0005] This utility model adopts the following technical solution: a slag removal device for a planar laser cutting machine, including a worktable, in which several transverse blades and vertically cooperating longitudinal blade seats are inserted; first rack-and-pinion linear drive mechanisms are arranged parallel to each other along the X-axis on both sides of the top of the worktable; a crossbeam is provided between two first rack-and-pinion linear drive mechanisms; a second rack-and-pinion linear drive mechanism that moves along the Y-axis is provided at the bottom of the crossbeam; a double saw blade slag removal mechanism is provided at the bottom of the second rack-and-pinion linear drive mechanism; the double saw blade slag removal mechanism includes a support frame; rotating shafts are symmetrically arranged on both sides of the bottom of the support frame; diamond-coated saw blades are fixedly installed on each rotating shaft; driven pulleys are connected to the outer ends of the rotating shafts; a dual-axis motor is installed at the center of the top of the support frame; driving pulleys are respectively provided on the two output shafts of the dual-axis motor; the driving pulleys are connected to the corresponding driven pulleys through synchronous toothed belts to form a closed-loop transmission structure.

[0006] Furthermore, the rotation planes of the two diamond-coated saw blades are parallel to the extension direction of the transverse blade.

[0007] Furthermore, the first rack-and-pinion linear drive mechanism includes a first rack and a first linear guide rail. Both the first rack and the first linear guide rail are mounted on the top of the worktable. A first movable plate is mounted on the top of the first linear guide rail. A first servo motor is mounted on the top of the first movable plate. The output end of the first servo motor passes through the first movable plate and is connected to a first gear. The first gear meshes with the first rack.

[0008] Furthermore, a cylinder is installed on the top of the first movable plate, and the output end of the cylinder is connected to the crossbeam.

[0009] Furthermore, the second rack-and-pinion linear drive mechanism includes a second rack and a second linear guide rail. The second rack and the second linear guide rail are respectively installed at the top and bottom of the crossbeam. A second movable plate is installed at the bottom of the second linear guide rail, and a second servo motor is installed at the top of the second movable plate. The output shaft of the second servo motor is connected to a second gear, which meshes with the second rack. A through slot for the movement of the output shaft of the second servo motor is provided at the top of the crossbeam, and the support frame is fixedly connected to the second movable plate.

[0010] Furthermore, the diamond-coated saw blade is fixedly installed to the rotating shaft by bolts.

[0011] The advantages of this invention are as follows: The rotation of the double diamond-coated saw blades enables high-speed and efficient removal of welding slag generated during cutting. The diamond coating possesses extremely high hardness and wear resistance, allowing for rapid cutting and material removal while ensuring the transverse blade remains clean, thus improving the precision and efficiency of the cutting machine. Utilizing a servo motor-driven rack-and-pinion linear drive mechanism and smooth cylinder propulsion, the movement of the double saw blade slag removal mechanism can be precisely adjusted. This ensures the slag removal mechanism can accurately clean welding slag within the required working range and can be independently adjusted in the X, Y, and Z axes, enhancing operational flexibility and adaptability, and greatly reducing the need for manual intervention. Operators only need to set parameters and monitor system operation, saving time and costs associated with manual slag removal and improving production efficiency. Attached Figure Description

[0018] See Figure 1-3As shown, a slag removal device for a planar laser cutting machine includes a worktable 1. Several transverse blades 101 and vertically cooperating longitudinal blade seats 102 are inserted into the worktable 1. First rack-and-pinion linear drive mechanisms 2 are arranged parallel to each other along the X-axis on both sides of the top of the worktable 1. A crossbeam 3 is provided between two first rack-and-pinion linear drive mechanisms 2. A second rack-and-pinion linear drive mechanism 4, which moves along the Y-axis, is provided at the bottom of the crossbeam 3. A double saw blade slag removal mechanism 5 is provided at the bottom of the second rack-and-pinion linear drive mechanism 4. The double saw blade slag removal mechanism 5 includes a support frame 51. Rotating shafts 52 are symmetrically arranged on both sides of the bottom of the support frame 51. Diamond-coated saw blades 53 are fixedly installed on each rotating shaft 52. Driven pulleys 54 are connected to the outer ends of the rotating shafts 52. A dual-axis motor 55 is installed at the center of the top of the support frame 51. Driven pulleys 56 are respectively provided on the two output shafts of the dual-axis motor 55. The driven pulleys 56 are connected to the corresponding driven pulleys 54 via synchronous toothed belts 57 to form a closed-loop transmission structure.

[0019] The rotating planes of the two diamond-coated saw blades 53 are parallel to the extension direction of the transverse blade 101, which can effectively remove the welding slag on both sides of the transverse blade 101.

[0020] The first rack-and-pinion linear drive mechanism 2 includes a first rack 21 and a first linear guide rail 22. Both the first rack 21 and the first linear guide rail 22 are mounted on the top of the worktable 1. A first moving plate 23 is mounted on the top of the first linear guide rail 22. A first servo motor 24 is mounted on the top of the first moving plate 23. The output end of the first servo motor 24 passes through the first moving plate 23 and is connected to a first gear 25. The first gear 25 meshes with the first rack 21. The first servo motor 24 drives the first rack 21 through the first gear 25, so that the first moving plate 23 mounted on the top of the worktable moves along the X-axis, which can remove slag from each transverse blade 101.

[0021] A cylinder 31 is installed on the top of the first moving plate 23. The output end of the cylinder 31 is connected to the crossbeam 3. The cylinder 31 can adjust the height of the crossbeam 3, thereby adjusting the height of the diamond-coated saw blade 53 so that its movement is not obstructed and the slag removal effect is improved.

[0022] The second rack-and-pinion linear drive mechanism 4 includes a second rack 41 and a second linear guide rail 42. The second rack 41 and the second linear guide rail 42 are respectively installed on the top and bottom of the crossbeam 3. A second moving plate 43 is installed at the bottom of the second linear guide rail 42. A second servo motor 44 is installed on the top of the second moving plate 43. The output shaft of the second servo motor 44 is connected to a second gear 45. The second gear 45 meshes with the second rack 41. A through slot is provided on the top of the crossbeam 3 for the movement of the output shaft of the second servo motor 44. The support frame 51 is fixedly connected to the second moving plate 43. The second moving plate 43 is driven to translate along the Y-axis direction by the second rack 41, the second linear guide rail 42, and the second servo motor 44, so that the two diamond-coated saw blades 53 can clear the entire transverse blade 101.

[0023] The diamond-coated saw blade 53 is fixedly installed to the rotating shaft 52 by bolts, which facilitates the replacement of the diamond-coated saw blade 53.

[0024] Working principle: After the laser cutting machine completes the plate processing, the first servo motor 24 drives the first rack 21 through the first gear 25, causing the first moving plate 23 mounted on the top of the worktable to translate along the X-axis, so that the two diamond-coated saw blades 53 are positioned on both sides of the transverse blade 101 that needs slag removal. The start cylinder 31 drives the double saw blade slag removal mechanism 5 to descend to the appropriate position. The dual-axis motor 55 drives the drive pulley 56 through the synchronous toothed belt 57 to achieve closed-loop transmission with the driven pulley 54, so that the diamond-coated saw blades 53 on the rotating shaft 52 rotate at high speed. The two diamond-coated saw blades 53 rotate at high speed, removing the welding slag generated during the cutting process from both sides of the transverse blade 101. Then, through the second rack 41, the second linear guide 42, and the second servo motor 44, the second moving plate 43 is driven to translate along the Y-axis, so that the two diamond-coated saw blades 53 can remove the entire transverse blade 101. Then, through the control of the first servo motor 24, slag removal can be performed on each transverse blade 101.
