Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser cutting machine technology, and more specifically, it relates to a side-mounted laser cutting machine with follow-up smoke exhaust. Background Technology
[0002] A laser cutting machine is a device that uses a high-energy laser beam focused by an optical system and combined with a CNC worktable to instantly melt, vaporize, or ablate metal and non-metal sheets, and then uses auxiliary gas to blow away the molten slag to complete the cutting. Its laser source is mostly fiber optic or CO2, with power ranging from hundreds of watts to tens of thousands of watts. It can process carbon steel, stainless steel, aluminum, copper, and titanium alloys, and can also cut acrylic, wood, ceramics, and composite materials. It produces narrow kerfs, small heat-affected zones, and bright edges, with a cut width of less than 0.1mm and dimensional accuracy of ±0.03mm. Its speed is several times faster than traditional punching and shearing, requires no molds, and allows for one-click switching of patterns, making it suitable for prototyping, mass production, and flexible manufacturing.
[0003] Laser cutting machines produce fumes during the cutting process. Most of these fumes are toxic and can affect the health of workers. The dust in the fumes can also accumulate on the guide rails or lenses, reducing the lifespan and precision of the equipment.
[0004] Most existing laser cutting machines have fixed smoke extraction ports. As the laser head moves, the fixed smoke extraction ports cannot extract the smoke in time, resulting in poor smoke extraction performance. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a side-mounted laser cutting machine with follow-up smoke exhaust.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a side-mounted laser cutting machine with follow-up smoke exhaust, comprising a base, a gantry frame slidably connected to the base, a laser head mounted on the end effector of the gantry frame, a cutting table placed below the gantry frame, a smoke exhaust pipe fixedly connected to the base, one end of the smoke exhaust pipe communicating with the air inlet of a fan, multiple smoke inlets at the upper end of the smoke exhaust pipe, a rubber belt placed above the smoke exhaust pipe, both ends of the rubber belt being fixedly connected to the smoke exhaust pipe, the rubber belt covering the multiple smoke inlets, a smoke extraction cover fixedly connected to one end of the gantry frame, the smoke extraction cover being located above the smoke exhaust pipe, multiple rollers rotatably connected to the upper inner end of the smoke extraction cover, the rubber belt passing over the multiple rollers, and smoke extraction ports on the side wall of the smoke extraction cover.
[0007] Preferably, the lower inner end of the smoke extraction cover is rotatably connected to two pressure rollers, which are located at both ends of the smoke extraction cover, and the rubber strip passes under the two pressure rollers.
[0008] Preferably, a fan is installed at the other end of the gantry frame, with the fan's air outlet facing the smoke extraction port.
[0009] Preferably, slide rails are fixedly connected to the two side walls of the base, and the two ends of the gantry frame are slidably connected to the two slide rails respectively.
[0010] Preferably, an anti-slip plate is fixedly connected to the upper end surface of the base.
[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. When the gantry crane moves the laser head to cut, the fume extraction cover moves with the gantry crane. Multiple rollers can always lift the rubber belt inside the fume extraction cover, so that the smoke can always enter the exhaust pipe through the fume extraction port and the smoke inlet. Moreover, the fume extraction port on the fume extraction cover is always located on one side of the laser head, so the smoke generated by cutting can be sucked in by the fume extraction port in time, which has a better smoke extraction effect than the existing technology. 2. By using a fan to blow the smoke towards the smoke extraction port, the smoke extraction effect is improved.
[0012] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it according to the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

For example, they can refer to a connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0018] Reference Figures 1 to 8This utility model provides a technical solution: a side-mounted laser cutting machine with follow-up smoke exhaust, including a base 1, a gantry frame 2 slidably connected to the base 1, a laser head mounted on the end effector of the gantry frame 2, and accessories such as the laser, chiller, and electrical box required for the operation of the laser head, all of which adopt existing technology and will not be described in detail here. The laser head is moved and cut by the gantry frame 2. A cutting table 3 is placed below the gantry frame 2, and the workpiece to be cut is placed on the cutting table 3. A smoke exhaust pipe 4 is fixedly connected to the base 1, and one end of the smoke exhaust pipe 4 is connected to the air supply. The air inlet of the machine 5 is connected, and the fan 5 is installed at one end of the exhaust pipe 4. The upper end of the exhaust pipe 4 has multiple smoke inlets 6. A rubber belt 7 is placed above the exhaust pipe 4. Both ends of the rubber belt 7 are fixedly connected to the exhaust pipe 4. The rubber belt 7 covers the multiple smoke inlets 6. One end of the gantry frame 2 is fixedly connected to a smoke extraction cover 8. The smoke extraction cover 8 is located above the exhaust pipe 4. Multiple rollers 9 are rotatably connected to the upper part of the inside of the smoke extraction cover 8. The rubber belt 7 passes over the multiple rollers 9. Smoke extraction ports 10 are opened on the side wall of the smoke extraction cover 8. like Figure 5 and Figure 6 The air outlet of the fan 5 is connected to the external pipeline. The suction force generated by the fan 5 can draw the smoke generated during cutting into the smoke extraction cover 8 through the smoke extraction port 10. The smoke in the smoke extraction cover 8 is drawn into the smoke exhaust pipe 4 through the smoke inlet 6. The smoke in the smoke exhaust pipe 4 is drawn out and discharged by the fan 5, thus completing the smoke exhaust. like Figure 3 and Figure 7 The rubber belt 7 can cover the smoke inlet 6 on the outside of the smoke cover 8, while the rubber belt 7 inside the smoke cover 8 is lifted by the roller 9, so that the rubber belt 7 will not cover the smoke inlet 6 inside the smoke cover 8, so that the suction of the fan 5 mainly acts on the smoke inlet 6 inside the smoke cover 8, and the suction of smoke extraction is stronger and more effective. The gantry frame 2 can drive the smoke extraction cover 8 to move, and during the movement of the smoke extraction cover 8, multiple rollers 9 can always lift the rubber belt 7 inside the smoke extraction cover 8, so that the smoke can always enter the exhaust pipe 4 through the smoke extraction port 10 and the smoke inlet 6. When the gantry 2 moves the laser head to cut, the fume extraction cover 8 moves with the gantry 2, so that the fume extraction port 10 on the fume extraction cover 8 is always located on one side of the laser head. The smoke generated by cutting can be sucked in by the fume extraction port 10 in time, which has a better smoke extraction effect than the existing technology.
[0019] Specifically, the lower inner end of the smoke cover 8 is rotatably connected to two pressure rollers 11, which are located at both ends of the smoke cover 8, and the rubber belt 7 passes under the two pressure rollers 11. like Figure 6 and Figure 7The two pressure rollers 11 press down on the rubber strips 7 on both sides of the smoke extraction port 10, which helps the rubber strips 7 to cover the smoke inlet 6 on the outside of the smoke extraction cover 8.
[0020] Specifically, a fan 12 is installed at the other end of the gantry frame 2, and the air outlet of the fan 12 faces the smoke extraction port 10, such as... Figure 2 and Figure 4 The fan 12 blows the smoke toward the smoke extraction port 10 to assist in smoke extraction and improve the smoke extraction effect.
[0021] Specifically, slide rails 13 are fixedly connected to the two side walls of the base 1, and the two ends of the gantry frame 2 are slidably connected to the two slide rails 13 respectively. like Figure 4 and Figure 8 Most existing slide rails are installed on the top of the base and require a dust cover to cover them. However, the dust cover is easily damaged. In contrast, the slide rail 13 of this application is installed on the side wall of the base 1, which eliminates the need for a dust cover. Furthermore, the side-mounted slide rail 13 has better structural rigidity and will not deform after long-term use.
[0022] The gantry 2 can be driven using existing technologies, such as gears and racks, to make it slide along the slide rail 13. This will not be elaborated further here.
[0023] Specifically, the upper surface of the base 1 is fixedly connected to an anti-slip plate, which makes it convenient for workers to step on it.
[0024] Working principle: When the gantry 2 moves the laser head to cut, the fume extraction cover 8 moves with the gantry 2. Multiple rollers 9 can always lift the rubber belt 7 inside the fume extraction cover 8, so that the smoke can always enter the exhaust pipe 4 through the fume extraction port 10 and the smoke inlet 6. Moreover, the fume extraction port 10 on the fume extraction cover 8 is always located on one side of the laser head, so the smoke generated by cutting can be sucked in by the fume extraction port 10 in time, which has a better smoke extraction effect than the existing technology.
[0025] It should be noted that all electrical components appearing in this application are connected to an external main controller and 220V AC mains power. The main controller can be a processor, alarm module, or drive module, etc., to control conventional known devices. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as bolts, rivets, and welding, which are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, and will not be described in detail here.
[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
