[0028] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the art to which the present invention belongs.

[0029] As described in the background technology, in the cutting head rotation scheme, the laser may irradiate in an unexpected direction, which poses a safety hazard. The use of a fixed protective plate affects the convenience of loading and unloading materials and reduces the overall operating efficiency.
[0030] In order to solve the above technical problems, the utility model proposes a folding protection mechanism for laser cutting machines, which can effectively block the laser during the cutting process to prevent the laser from injuring people or causing fires, and can be folded up during loading and unloading without affecting the working efficiency. Through this design, we not only improve the safety of the operation, but also ensure the efficient operation of the equipment and the convenience of operation.
[0031] like Figure 1 As shown, the folding protection mechanism includes a shielding component 1, a lifting bracket 2 and a driving mechanism 3.
[0032] like Figure 2 As shown, the shielding assembly 1 includes a plurality of folding baffles 11, and the plurality of folding baffles 11 are slidably sleeved in sequence along the vertical direction; the lifting bracket 2 includes a first bracket 21 and a second bracket 22, and the first bracket 21 and the second bracket 22 are rotatably connected in the middle to form an X shape, and the driving mechanism 3 can drive the first end (i.e. Figure 2 The left end of the middle bracket 21 moves horizontally, and the second end of the first bracket 21 (i.e. Figure 2 The first end of the second bracket 22 (i.e. Figure 2 The left end of the middle part) is slidably connected to the top folding baffle 11, and the second end (i.e. Figure 2 The middle right end) is rotatably connected to the bottom folding baffle 11.
[0033] The folding protection mechanism includes a plurality of folding baffles 11 which are connected in sequence. Under the cooperation of the driving mechanism 3 and the X-shaped lifting bracket 2, the plurality of folding baffles 11 can be unfolded and folded. When cutting, the folding baffles 11 can be unfolded one by one by lifting and lowering operations (such as Figure 4 , Figure 5 As shown in the figure), a complete protective barrier is formed to effectively block the laser beam and avoid harm to the surrounding environment and operators. When changing materials, the folding baffles 11 can be folded one by one by lifting and lowering operations (as shown in the figure). Figure 6 The laser beam can be blocked when the cutting head of the laser steel cutting machine rotates, solving the problem of machine beam irradiation hazards. The folding protection mechanism can be folded up during loading and unloading, effectively improving safety while ensuring convenient operation.
[0034] like Figure 2 As shown, the shielding assembly 1 includes a side plate 12 and a back plate 13, and the side plates 12 are arranged on both sides of the back plate 13 to form a U-shaped (such as Figure 1, Figure 3 As shown in FIG. 1 , the two ends of the U-shaped shielding component 1 are bent inward, wherein the top shielding component 1 is also provided with a top plate 14, and the bottom shielding component 1 is also provided with a bottom plate 16. Such a design not only increases the strength of the structure, but also enables it to fully cover all directions where the laser beam may leak in the unfolded state, forming a complete protective barrier. The provision of the top plate 14 and the bottom plate 16 facilitates the installation of the driving mechanism 3 and the lifting bracket 2.
[0035] The cross-section of the upper shielding component 1 is smaller than that of the lower shielding component 1. Among the two adjacent shielding components 1, the upper shielding component 1 is sleeved in the lower shielding component 1, that is, a nested manner in which the upper one is small and the lower one is large. Of course, it is understandable that in other embodiments, a nested manner in which the upper one is large and the lower one is small can also be adopted.
[0036] By nesting the folding baffles 11, multiple shielding assemblies 1 can be stacked together when not in use to reduce the space occupied, and can be quickly unfolded when needed to form a complete protective barrier. This design makes the protective mechanism more compact and easy to store and transport while ensuring the protective effect.
[0037] like Figure 2 As shown, a mounting seat is provided at one end of the top plate 14 of the top shielding assembly 1 away from the driving mechanism 3, and at one end of the bottom plate 16 of the bottom shielding assembly 1 away from the driving mechanism 3, the second end of the first bracket 21 is rotatably mounted on the mounting seat of the top plate 14, and the second end of the second bracket 22 is rotatably mounted on the mounting seat of the bottom plate 16. This design ensures that during the lifting process, the folding baffle 11 can move smoothly with the lifting bracket 2 without the risk of shaking or falling off.
[0038] like Figure 2 As shown, the first end of the first bracket 21 is rotatably mounted with a lower guide wheel 24, and the lower guide wheel 24 can roll on the bottom plate 16, the lower side of the top plate 14 is mounted with a track 15, and the first end of the second bracket 22 is mounted with an upper guide wheel 23, and the upper guide wheel 23 can roll on the track 15. The design of the guide wheel and the track 15 ensures that the bracket can slide smoothly during the lifting process, reduces friction and resistance, and improves the smoothness of the operation. This design not only improves the lifting stability of the protective mechanism, but also reduces the load of the driving mechanism 3, thereby improving the overall efficiency.
[0039] The driving mechanism 3 includes a bearing seat 37, a lead screw 34 and a lead screw nut. The bearing seat 37 is mounted at both ends of the bottom plate 16. Both ends of the lead screw 34 are rotatably mounted on the bearing seat 37. The lead screw nut is arranged at the first end of the first bracket 21 and mounted on the lead screw 34. The bearing seats 37 at both ends of the lead screw 34 are used to support the lead screw 34. The lead screw nut is installed between the two lower guide wheels 24 and is driven by the lead screw 34. This design ensures the stability and accuracy of the driving process, and can accurately adjust the lifting position of the protection mechanism according to needs, ensuring that reliable protection can be provided under different working conditions.
[0040] The bottom plate 16 is also provided with a limit bracket 36 and a motor bracket 33, through which the lead screw 34 passes, and the limit bracket 36 and the motor bracket 33 are respectively located at both ends of the lead screw nut. At the same time, the limit bracket 36 and the motor bracket 33 play a role of hard limit, preventing the lead screw nut from moving beyond a predetermined range. This design not only improves the accuracy of the driving mechanism 3, but also increases the reliability and safety of the entire system.
[0041] A travel switch 35 is installed on the end of the limit bracket 36 facing the lead screw nut, and on the end of the motor bracket 33 facing the lead screw nut. When the first bracket 21 moves to a predetermined position, the travel switch 35 is triggered to automatically stop the driving motor 31 to avoid exceeding the limit range, further improving the safety and automation of the protection mechanism.
[0042] The driving mechanism 3 also includes a driving motor 31, which is mounted on the motor bracket 33. The motor bracket 33 has a notch to adjust the motor center height. The output shaft of the driving motor 31 and the end of the lead screw 34 are both equipped with synchronous wheels, and the two synchronous wheels are connected by a synchronous belt 32. The rotation of the driving motor 31 drives the synchronous belt 32 to drive the lead screw 34 to rotate, thereby realizing the movement of the lead screw nut. This design ensures the high efficiency and stability of the driving system. Through the transmission mode of the synchronous belt 32, the error of the mechanical transmission can be reduced, and the overall accuracy and reliability can be improved. In addition, installing the driving motor 31 on the motor bracket 33 reduces the space occupied in the width direction.
[0043] Based on the above-mentioned folding protection mechanism, this embodiment also provides a laser cutting machine, in which the folding protection mechanism described in the above-mentioned embodiment is provided. By integrating the above-mentioned protection mechanism, it is ensured that all-round laser protection is provided during the cutting process, thereby improving work safety and efficiency. At the same time, the design of the laser cutting machine fully considers the convenience of operation and the compactness of the structure, and is suitable for efficient cutting of various profiles. This design not only improves the performance of the laser cutting machine, but also provides users with a safer and more convenient operating experience.
[0044] Although the above describes the specific implementation methods of the utility model in conjunction with the accompanying drawings, it is not intended to limit the protection scope of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the protection scope of the utility model.
