[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Existing laser cutting machines pose potential safety risks during operation due to laser radiation and mechanical movement, which can easily lead to accidents. This embodiment provides a beam-mounted safety light curtain installation device for a laser cutting machine. Please refer to... Figures 1-5This system enables real-time monitoring and prevention of unauthorized intrusion, providing safety warnings and shutdown protection, thereby improving operational safety. The laser cutting machine's beam-following safety light curtain mounting device includes a beam 1, which is fixed to the right-side safety light curtain bracket 21 and the left-side safety light curtain bracket 22 by screws. This facilitates the assembly and disassembly of the right-side and left-side safety light curtain brackets 21 and 22, improving ease of assembly. Two servo drive motors are installed inside the beam 1, with symmetrically distributed sliders at its bottom. The guide rails and sliders allow the drive motors to rotate the connecting gears, which mesh with the bed rack, enabling the light curtain assembly to follow the machine. The beam 1 is equipped with an installation mechanism 2 to improve operational safety, and a protective noise reduction mechanism 3 to prevent debris from splashing. The installation mechanism 2 can monitor and prevent unauthorized intrusion of personnel or objects into the dangerous areas of the laser cutting machine in real time, providing safety warnings and shutdown protection, thus improving operational safety. The protective noise reduction mechanism 3 prevents debris from splashing during cutting and also has a certain noise reduction effect.

[0029] In order to improve the operational safety and workpiece production quality of the laser cutting machine, the mounting mechanism 2 includes a right-side safety light curtain bracket 21 and a left-side safety light curtain bracket 22 movably mounted on the crossbeam 1. A cable tray cover plate 1 23 is movably mounted on the left-side safety light curtain bracket 22, a cable tray cover plate 24 24 25 25 26 26 26 26 24 25 25 25 26 26 26 27 28 23 24 25 25 26 26 26 27 28 29 22 23 24 25 25 26 26 26 27 28 29 21 22 26 26 28 29 21 ...

[0030] Example 2

[0031] Based on Example 1, such as Figures 1-5 As shown, existing laser cutting machines have potential safety risks such as laser radiation and mechanical movement during operation, which can easily lead to safety accidents. However, existing laser cutting machines tend to generate debris when cutting workpieces. If debris splashing is not prevented, the cutting safety of the laser cutting machine can be reduced. Therefore, this device is also equipped with a structure to prevent debris splashing and enhance cutting safety performance.

[0032] During the use of a laser cutting machine, in order to prevent the flying of debris generated during cutting and improve the protective performance of the device, the protective noise reduction mechanism 3 includes a mounting column 31 movably mounted on a crossbeam 1. A protective seat 32 is mounted on the mounting column 31, and a rotary motor 33 is mounted on the protective seat 32. The output end of the rotary motor 33 is connected to a mounting rod 34, and a drive gear 35 is mounted on the mounting rod 34. Two sets of limiting sleeves 36 are installed inside the protective seat 32. Toothed plates 37 that mesh with the drive gear 35 are slidably connected to the limiting sleeves 36. The toothed plates 37 move in opposite directions, thereby expanding the protective area and improving the protective effect. One set of toothed plates 37 is fixed to one set of protective plates 38, which facilitates the simultaneous unfolding of the two sets of protective plates 38. Protective plates 38 are mounted on the toothed plates 37. A noise reduction component 301 for reducing cutting noise is provided inside the protective seat 32. The operation of the rotary motor 33 drives the mounting rod 34 to rotate, which in turn drives the drive gear 35 to rotate. Under the support of the limit sleeve 36, the two sets of toothed plates 37 move towards each other, thereby extending the two sets of protective plates 38 from the protective base 32, thus expanding the protective area and improving the protective effect.

[0033] In order to reduce the noise generated during the use of the laser cutting machine and improve the cutting environment, the noise reduction component 301 includes a worm gear sleeve 3011 installed on the mounting rod 34, two sets of support plates 3012 installed on the limiting sleeve 36, the support plates 3012 being symmetrically distributed at both ends of the rotating rod 3013, which makes the rotating rod 3013 rotate more smoothly, the rotating rod 3013 being rotatably installed on the support plate 3012, the rotating rod 3013 being equipped with a worm wheel 3014 that meshes with the worm gear sleeve 3011, a threaded rod 3015 being installed at one end of the rotating rod 3013, and a noise reduction plate 3016 being threadedly connected to the threaded rod 3015. The noise reduction plate 3016 passes through the protective seat 32 and is connected to the rotating rod 3013, so that the noise reduction plate 3016 can be unfolded at the same time as the protective plate 38 is unfolded, thereby playing a role in noise reduction. A positioning rod 3017 that is slidably connected to the noise reduction plate 3016 is installed inside the protective seat 32. The rotation of the mounting rod 34 drives the worm sleeve 3011 to rotate. With the cooperation of the worm wheel 3014 and the worm sleeve 3011, the rotating rod 3013 rotates, thereby driving the threaded rod 3015 to rotate. Under the limiting support of the positioning rod 3017, the noise reduction plate 3016 is extended from the protective seat 32, thus playing a role in noise reduction.
