[0023] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments.

[0024] With reference to Figures 1-4 The laser cutting machine grid slag removal device comprises a bottom support 12, sword grids 11 which are fixedly connected to the bottom support 12 and are distributed in parallel and at intervals, a hand-held support 1, two rotating rollers 4 which are arranged in parallel with respect to the axis and are rotatably connected to the hand-held support 1, impact ropes 5 which are distributed on the outer circumferences of the rotating rollers 4, a hand-held part at one end of the hand-held support 1, and a power module 6 which is installed at the end of the hand-held support 1 which is far away from the hand-held part, wherein the power module 6 is used to drive the two rotating rollers 4 to rotate, and the impact ropes 5 can impact the sword grids 11 which are located between the two rotating rollers 4 during work.

[0025] During use, an operator holds the hand-held part of the hand-held support, and the impact ropes which are located between the two rotating rollers are aimed at the grid area of the laser cutting machine. After the power module is started, the two rotating rollers which are arranged in parallel with respect to the axis are driven to rotate at a high speed, and the impact ropes which are distributed on the outer circumferences are driven to move with the rotating rollers to generate a rotating impact action. The impact ropes continuously impact the sword grids which are located between the two rollers from the bottom to the top under the action of centrifugal force, so that the molten slag or impurities which are attached to the surface of the grid are knocked off. By moving the hand-held support, continuous impact cleaning of the whole row of grids is realized.

[0026] Compared with the traditional manual knocking or steel brush cleaning mode, the present application is simple to operate, has high impact cleaning efficiency, can effectively remove the molten slag which is attached to the surface of the sword grid, and reduces the labor intensity of manual work. The impact ropes adopt a flexible structure, can effectively avoid damage to the grid, and improve the applicability and safety of the device. The device can be used as a portable tool, for example, only one device is needed for a plurality of laser cutting machines in a factory.

[0027] With reference to Figure 2 During work, the impact ropes 5 on the two rotating rollers 4 all impact the sword grids 11 from the bottom to the top. During work, the power module drives the two rotating rollers to rotate, and the impact ropes on the rotating rollers move accordingly. Since the installation mode and the rotation direction are reasonable, the impact ropes move in a trajectory from the bottom to the top under the action of centrifugal force, continuously impact the surface of the sword grid from the bottom to the top, and effectively knock off the molten slag which is attached to the sword grid. Since the movement trajectory of the impact ropes is to impact from the bottom to the top, the sharp edges of the sword grid can be effectively avoided to directly cut and contact the impact ropes, and the service life is improved.

[0028] Preferably, the maximum distance of the impact ropes 5 on the two rotating rollers 4 is less than the maximum distance between adjacent three sword grids 11, so that the impact ropes 5 can avoid impacting the two sword grids 11 on the two sides during work, and the sword grids on the two sides can avoid cutting the impact ropes 5.

[0029] As an implementation, the striking rope 5 comprises a flexible body 8 and a striking head 9, one end of the flexible body 8 is fixedly connected with the rotating roller 4, and the other end is fixedly connected with the striking head 9; the flexible body 8 is a steel wire rope or a chain. The striking rope is designed in a flexible structure, which can realize stable striking action in rotating motion. The flexible body such as a steel wire rope or a chain has good wear resistance and toughness, which can provide effective striking force, the striking head concentrates the impact force, and the cleaning efficiency is improved.

[0030] The striking ropes 5 on the two rotating rollers 4 are staggered and arranged, and the striking ropes 5 on the two rotating rollers 4 have overlapping areas, as shown in Figure 3 , by staggering arrangement, the striking coverage of the striking rope 5 on the sword grid can be improved.

[0031] The hand-held support 1 is fixedly connected with a cover shell 10, which can cover the area of the rotating roller 4 away from the grid bar, and the splashing of the molten slag falling through the cover shell 10 is avoided.

[0032] The hand-held support 1 comprises end supports 2 located at both ends of the rotating roller 4 and a hand lever 3 fixedly connected with the two end supports 2, and the rotating roller 4 is rotatably connected with the end supports 2; the hand lever 3 is an adjustable telescopic rod, which is convenient for adjusting the length of the hand-held support used by the worker.

[0033] The power module 6 comprises a protective shell 13 fixedly connected with the end support 2, a motor 14 fixedly installed in the protective shell 13, a gear 15 fixedly connected with one end of each rotating roller 4 inside the protective shell 13, and two gears 15 meshing and driving each other, wherein one of the gears 15 is in driving connection with the power output shaft of the motor 14. The power module comprises a protective shell installed on the end support, a motor fixedly installed in the protective shell, and a gear on one of the rotating rollers in driving connection with the output shaft of the motor. The gear meshes with the gear on the other rotating roller, so that the synchronous rotation of the two rotating rollers is realized under the driving of the motor, and the high-speed movement of the outer circumferentially distributed striking ropes is realized, thereby completing the continuous striking and slag removing operation on the grid bars.

[0034] Referring to Figure 4 , the tail wheel 7 is rotatably installed at the end of the hand-held support 1 away from the hand-held part, and the axis of the tail wheel 7 is perpendicular to the sword grid 11, so that only the hand lever 3 needs to be turned up to support the entire device by the tail wheel 7, and then the entire device can be pushed and pulled along the length direction of the sword grid.

[0035] The tail wheel 7 is preferably greater than the length of three adjacent sword grids, so that the tail wheel can be better supported on the sword grid to avoid tilting to both sides.

[0036] The length of the rotating roller 4 is preferably greater than one-third of the length of the sword grid and less than the total length of the sword grid, so that a longer sword grid can be cleaned at one time by the large-span rotating roller 4.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
