[0019] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed description is given in conjunction with the embodiments.

[0020] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0021] Please refer to Figure 1 , Figure 2 and Figure 3 The present invention provides a slag cleaning device 100 for a laser cutting machine workbench, comprising: a fixed base 1 and a rotating shovel 2.

[0022] The fixed base 1 includes a fixed bottom plate 11 and two support plates 12. The two support plates 12 are erected parallel to the upper surface of the fixed bottom plate 11. The rotary shovel 2 is rotatably mounted between the two support plates 12. The fixed bottom plate 11 is provided with an avoidance hole 111 for the rotary shovel 2 to pass through when rotating.

[0023] The rotary shovel 2 includes a blade 21, a rotating shaft 22 and a handle 23. One end of the blade 21 is provided with an elongated slot 211 extending along the first direction X, and the width of the slot 211 in the second direction Y is slightly wider than the width of the sword grid on the workbench of the laser cutting machine, and is used to remove slag on both sides of the sword grid. The other end of the blade 21 is connected to the handle 23, and the rotating shaft 22 is fixed on the lower surface of the blade 21, and the two ends of the rotating shaft 22 respectively pass through the two support plates 12, which are used to rotatably mount the rotary shovel 2 on the two support plates 12 along the rotating shaft 22.

[0024] Preferably, the width of the notch 211 is equal to the thickness of the sword fence plus 2 mm. This arrangement facilitates shoveling the slag on the sword fence.

[0025] Preferably, two symmetrical through holes 121 are formed on the two support plates 12, and the two ends of the rotating shaft 22 are respectively inserted into the two through holes 121. Using through holes to mount the rotating shaft 22 not only simplifies the structure, but also makes it easy to process.

[0026] More preferably, the rotating shaft 22 is a double-headed screw, and the slag cleaning device 100 further includes two self-locking nuts 3 for fixing the double-headed screw in the two through holes 121. The double-headed screw 22 and the self-locking nuts 3 are used to facilitate installation, disassembly, maintenance and replacement.

[0027] Preferably, the rotating shaft 22 is fixed to the lower surface of the scraper 21 by welding. The welding method is easy to operate and the fixed structure is relatively stable.

[0028] Preferably, the axial direction of the rotating shaft 22 is parallel to the second direction Y. This arrangement can make the rotating shovel 2 rotate more stably and improve the efficiency and effect of shoveling away the slag.

[0029] Preferably, the handle 23 is T-shaped, and two sections of round tubes are sleeved on both sides of the handle 23. This arrangement is convenient for holding with both hands and is not easy to hurt the hands.

[0030] Preferably, the handle 23 has a structure that is adjustable in length in the first direction X. In this way, the length can be adjusted appropriately according to the height of different operators, thereby improving the efficiency of shoveling slag.

[0031] Preferably, the notch 211 and the center line of the scraper 21 parallel to the first direction X coincide with each other. This arrangement can ensure that the notch 211 is subjected to balanced forces on both sides when scraping away the slag, and is not prone to tipping over.

[0032] Preferably, the distance between the inner opposite surfaces of the two support plates 12 is equal to the width of the scraper 21 in the second direction Y. This can ensure that the scraper 21 is not easy to slide left and right, and improve the stability when scraping slag.

[0033] The use process of the slag cleaning device of the laser cutting equipment of the present invention is as follows:

[0034] Align the notch of the slag cleaning device with the sword grid of the laser cutting machine workbench. The user continuously presses the handle of the rotating shovel up and down so that the notch continuously pries the slag on the sword grid under the action of external force, thereby achieving the purpose of cleaning the slag from the sword grid.

[0035] During operation, a thick iron plate can be placed on one side of the workbench to facilitate the operator to stand, while also effectively preventing the sword grid from tilting up during the cleaning process.

[0036] The slag cleaning device for a laser cutting machine workbench of the present invention has a reasonable design and good actual use effect, which meets expectations. It can not only clean the slag of the sword grid of the laser cutting machine conveniently, quickly, efficiently and labor-savingly, but also has a low manufacturing cost.

[0037] The present invention has been described by the above-mentioned relevant embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, changes and modifications made without departing from the spirit and scope of the present invention are all within the scope of patent protection of the present invention.
