Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting platforms, in particular to a laser machine anti-splash device. Background Art

[0002] When a laser machine cuts a material, it emits light through a laser tube, which is then reflected and focused onto the laser head by a reflector and focusing lens. The focused intense light is then emitted onto the material to be cut or engraved, causing it to melt rapidly due to the high temperature, achieving the desired cutting or engraving effect.

[0003] In existing technology, the work surface of a laser cutting machine consists of a monolithic box with a honeycomb panel placed in the center. Because the honeycomb panel is welded and then polished manually or machine-made from mild steel, it can deform slightly during polishing, resulting in a significant height difference on the tabletop, which affects the depth of the cut. Furthermore, the wavelength of the CO2 laser's light spot, when it strikes the honeycomb metal plate, can cause secondary damage to the edges and surface of the product through refraction. Therefore, a laser machine splash shield has been proposed to address this issue. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a laser machine splash-proof device in view of the deficiencies in the above-mentioned prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a laser machine splash-proof device, comprising a steel plate, a support shaft fixedly connected to the steel plate, a pulley rotatably connected to the support shaft via a bearing, and the steel plate is fixed to the entire machine bracket of the laser machine via screws;

[0006] A rubber conveyor belt is provided on the pulley, and a graphite film is laid flat on the upper surface of the steel plate. The graphite film is horizontally arranged on a platform on the plane of the laser machine. The platform is always in a horizontal position. The graphite film can be rolled up by the pulley without affecting the use of other products.

[0007] Preferably, there are two support shafts, and the two support shafts are fixedly connected to the left and right sides of the steel plate respectively. The arrangement of the support shafts can facilitate the installation of the pulley.

[0008] Preferably, there are two pulleys, and the two pulleys are rotatably connected to the two ends of the support shaft through bearings. The arrangement of the pulleys can facilitate the winding of the graphite film.

[0009] The utility model adopts the above technical solution, which can bring the following beneficial effects:

[0010] The laser machine's splash-proof device installs a steel plate on the original honeycomb plate platform position of the laser machine's table and fixes it with screws. During laser machine operation, the high flatness of the steel plate solves the problem of the flatness of the honeycomb plate table, and improves the problem of large height differences in the flatness of the honeycomb plate. The graphite film is resistant to high temperatures and diffuses quickly and stably. The CO2 light source cannot damage the surface of the graphite film. The cutting of the CO2 light source is ineffective on the graphite film. The black color of the graphite film itself has the property of absorbing light, thereby solving the purpose of secondary damage to the product caused by high temperature and light refraction. The graphite film can be retracted and extended by a pulley and can be rolled up when not needed without affecting the operation of other products. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are 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.

[0017] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "disposed" should be understood in a broad sense. For example, they may refer to fixed connection or disposition, detachable connection or disposition, or integral connection or disposition. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0018] See also Figure 1-3 One embodiment of the utility model is: a laser machine splash protection device, comprising a steel plate 1, a support shaft 3 is fixedly connected to the steel plate 1, a pulley 4 is rotatably connected to the support shaft 3 through a bearing, and the steel plate 1 is fixed to the entire machine bracket of the laser machine by screws;

[0019] A rubber conveyor belt 5 is provided on the pulley 4. A graphite film 2 is laid flat on the upper surface of the steel plate 1. The graphite film 2 is horizontally arranged on the platform of the laser machine plane. The platform is always in a horizontal position. The graphite film 2 can be rolled up by the pulley 4 without affecting the use of other products.

[0020] Install the steel plate 1 on the original honeycomb plate platform position of the laser machine and fix it with screws. When the laser machine is operating, the high flatness of the steel plate 1 solves the problem of the flatness of the honeycomb plate table, and improves the problem of large height difference in the flatness of the honeycomb plate. The graphite film 2 is resistant to high temperatures and is stable. The CO2 light source cannot damage the surface of the graphite film 2. The cutting of the CO2 light source is ineffective on the graphite film 2. The black color of the graphite film 2 itself has the property of absorbing light, thereby solving the purpose of causing secondary damage to the product due to high temperature and light point refraction. The graphite film 2 can be retracted and released by the pulley 4, and can be rolled up when not needed without affecting the operation of other products.

[0021] There are two support shafts 3 , which are fixedly connected to the left and right sides of the steel plate 1 respectively. The arrangement of the support shafts 3 facilitates the installation of the pulley 4 .

[0022] There are two pulleys 4 , which are rotatably connected to both ends of the support shaft 3 through bearings. The arrangement of the pulleys 4 makes it convenient to roll up the graphite film 2 .

[0023] The steel plate 1 is a platform with high flatness and high precision, and the graphite film 2 laid flat on the platform of the steel plate 1 does not affect the flatness of the platform.

[0024] Working principle: When starting the actual operation, the pulley 4 is rotated to spread the graphite film 2 flat on the alloy steel plate 1 platform. Because the flatness of the steel plate 1 as a supporting table is measured to be 0.01 degrees, which is within the controllable range, a piece of material is placed on the graphite film 2 and the CO2 light source is turned on for cutting. After completion, check that there is no obvious damage on the edge surface of the product because the graphite film 2 absorbs the remaining light source and the product temperature is normal and within the controllable range because the graphite film 2 diffuses the heat during high-temperature cutting in a fan shape through the graphite film 2. The cutting of this product is completed, the inspection is usable, and the quality meets the standards.

[0025] This utility model provides a laser machine splash protection device. There are many methods and approaches to implement this technical solution. The above is only a preferred embodiment of the utility model. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of the utility model. Such improvements and modifications should also be considered as the scope of protection of the utility model. All components not specified in this embodiment can be implemented using existing technologies.
