Description

Technical Field

[0001] This utility model relates to a fume removal device, specifically a fume removal device for laser marking, and belongs to the technical field of fume removal devices. Background Technology

[0002] Laser marking refers to the process of using a focused laser beam to act on the surface of a material, utilizing photothermal or photochemical effects to form permanent text, patterns, barcodes, and other markings. Laser marking equipment is often used in conjunction with a fume extraction device, which is a dedicated environmental purification device. The air intake of the device is usually placed directly in the marking area to capture the fume and dust generated in the marking area, preventing their spread, thus protecting the health of operators, protecting the optical system of the equipment, maintaining a clean production environment, and meeting environmental emission requirements.

[0003] However, traditional fume extraction devices typically involve directly locking the dust hood to the end of the corrugated pipe using clamps during assembly. Therefore, when changing dust hoods of different sizes, the clamps need to be repeatedly disassembled, making the process cumbersome. Furthermore, repeated bending or pulling at the connection between the dust hood and the corrugated pipe can easily cause the clamps to loosen, resulting in poor stability. Additionally, the dust suction pipe is usually placed directly on the operating table of the marking equipment, making it prone to slipping under external force, thus reducing its practicality.

[0021] 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.

[0022] Please see Figures 1-6 As shown, a smoke and dust removal device for laser marking includes a purifier body 1, a main structure 2 mounted on the purifier body 1, and a top cover 201. The top cover 201 is fixedly connected to the purifier body 1, and a connection interface 202 is fixedly connected to the top cover 201. A suction pipe 203 is fixedly connected to the connection interface 202. Four casters 204 are fixedly connected to the bottom of the purifier body 1. The end of the suction pipe 203 is fixedly connected to the end pipe 301. By pushing the purifier body 1, the position of the device is adjusted by the four casters 204 at its bottom, so that the suction nozzle 308 is aligned with the smoke generation area of ​​laser marking. Then, the braking structure of the casters 204 is locked to prevent the device from shifting during operation. During the operation phase, the purifier body 1 is started, and the device captures the smoke and dust generated in the marking area through the suction nozzle 308. The smoke and dust enter the interior of the purifier body 1 through the end pipe 301, the suction pipe 203, and the connection interface 202 for purification.

[0023] As a technical optimization of this utility model, the main structure 2 is provided with a quick-release structure 3, which includes an end tube 301. The end tube 301 is connected to the main structure 2. One end of the end tube 301 is fixedly connected to an installation ring 302. Both sides of the installation ring 302 are fixedly connected to connecting blocks 303. The end of the connecting block 303 is threadedly connected to a knob 306. The knob 306 has a "T" shaped cross-section. The top of the knob 306 has a drive hole 307. The other end of the end tube 301 is slidably connected to a vacuum nozzle 308. First, prepare a vacuum nozzle 308 of the appropriate size, and ensure that the first sliding grooves 309 on both sides of the nozzle 308 are aligned with the end tube 301. With the connecting block 303 and knob 306 aligned, align the end of the suction nozzle 308 with the positioning block 311 to the end of the end tube 301. A pressure ring 304 is slidably connected to the center of the end tube 301. A spring 305 is fixedly connected between the pressure ring 304 and the mounting ring 302. The pressure ring 304 is slidably connected to the connecting block 303. The end of the suction nozzle 308 near the mounting ring 302 abuts against the pressure ring 304. Both sides of the suction nozzle 308 have a first sliding groove 309 and a limiting groove 310, which are interconnected. The knob 306 is slidably connected to the adjacent first sliding groove 309. A positioning block 311 is fixedly connected to the dust nozzle 308 near the first slide groove 309. A connecting block 303 is slidably connected to the adjacent positioning block 311. The two connecting blocks 303 are symmetrically arranged. The positioning block 311 has an "L" shape, allowing the connecting block 303 to slide against the positioning block 311, thus achieving initial guiding positioning. Simultaneously, the knob 306 is aligned with the first slide groove 309 and slides along the groove. During this process, the end face of the dust nozzle 308 will abut against the pressure ring 304, causing the pressure ring 304 to slide along the outer wall of the end tube 301 towards the mounting ring 302, compressing the spring 305. When the knob 306 slides to the end of the first slide groove 309... Then rotate the suction nozzle 308 to move the knob 306 from the first slide groove 309 into the connected limiting groove 310. Then release the suction nozzle 308. At this time, the spring 305 returns to its original position and pushes the pressure ring 304 against the end face of the suction nozzle 308 to achieve axial compression. At the same time, it drives the bottom of the knob 306 to press against the inner wall of the limiting groove 310, thereby fixing the suction nozzle 308 and completing the docking of the suction nozzle 308 and the end tube 301. If reinforcement is required, a hex wrench can be inserted into the drive hole 307 at the top of the knob 306. Then rotate the "T"-shaped knob 306 so that its bottom presses against the inner wall of the limiting groove 310 to further improve the firmness.

[0024] As a technical optimization of this utility model, the dust suction nozzle 308 is provided with an installation structure 4, which includes an installation sleeve 401. The bottom of the dust suction nozzle 308 is provided with the installation sleeve 401, and a second sliding groove 402 is opened on the installation sleeve 401. An installation block 403 is fixedly connected to the bottom surface of the dust suction nozzle 308. A threaded rod 404 is threadedly connected to the installation block 403. A slider 405 is rotatably connected to the end of the threaded rod 404. The slider 405 is slidably connected to the second sliding groove 402. The installation sleeve 401 is locked to the operating table of the laser marking equipment with bolts. Then, according to the marking area or the position of the component... Adjust the relative position of the marking area of ​​the suction nozzle 308, fix the slider 405 to the mounting block 403 on the bottom surface of the suction nozzle 308 by the threaded rod 404, and then insert the slider 405 into the second slide groove 402 on the mounting sleeve 401 and slide along the second slide groove 402. When the suction nozzle 308 is aligned with the designated laser marking area, rotate the threaded rod 404 to make the slider 405 press against the inner wall of the second slide groove 402, thereby completing the adjustment of the position of the suction nozzle 308 and limiting the position after adjustment. This prevents the suction nozzle 308 from falling off the operating table of the laser marking equipment under external force and improves its stability.

[0025] In use, this invention first requires a vacuum nozzle 308 of the appropriate size. Ensure that the first sliding grooves 309 on both sides correspond to the connecting blocks 303 and knobs 306 on the end tube 301. Next, align the end of the vacuum nozzle 308 with the positioning block 311 to the port of the end tube 301, allowing the connecting block 303 to slide against the positioning block 311 for initial guidance and positioning. Simultaneously, align the knob 306 with the first sliding groove 309 and slide it along the groove. During this process, the end face of the vacuum nozzle 308 will abut against the pressure ring 304, causing the pressure ring 304 to slide along the outer wall of the end tube 301 towards the mounting ring 302, compressing the spring 305. When the knob 306 slides to the end of the first sliding groove 309, rotate the vacuum nozzle 308. The knob 306 is rotated from the first slide groove 309 into the connected limiting groove 310. Then, the suction nozzle 308 is released. At this time, the spring 305 returns to its original position and pushes the pressure ring 304 against the end face of the suction nozzle 308 to achieve axial compression. At the same time, the bottom of the knob 306 is driven to press against the inner wall of the limiting groove 310, thereby fixing the suction nozzle 308 and completing the connection between the suction nozzle 308 and the end tube 301. If reinforcement is required, a hex wrench can be inserted into the drive hole 307 at the top of the knob 306, and then the "T"-shaped knob 306 can be rotated to press its bottom against the inner wall of the limiting groove 310 to further improve the firmness. After the connection between the suction nozzle 308 and the end tube 301 is completed, the mounting sleeve 401 can be installed by bolts. Locked onto the operating table of the laser marking equipment, the relative position of the dust suction nozzle 308 to the marking area is adjusted according to the marking area or the position of the component. The slider 405 is fixed to the mounting block 403 on the bottom surface of the dust suction nozzle 308 via the threaded rod 404. Then, the slider 405 is inserted into the second slide groove 402 on the mounting sleeve 401 and slides along the second slide groove 402. When the dust suction nozzle 308 is aligned with the designated laser marking area, the threaded rod 404 is rotated to make the slider 405 press against the inner wall of the second slide groove 402. This completes the adjustment of the position of the dust suction nozzle 308 and limits its position after adjustment, preventing the dust suction nozzle 308 from falling off the operating table of the laser marking equipment under external force, improving its stability. Afterwards, confirm... The top cover 201 of the purifier body 1 is firmly connected to the interface 202. One end of the suction pipe 203 is fixed to the interface 202, and the other end is fixedly connected to the end pipe 301. Check that all connections are secure. The overall assembly of the device is completed. Push the purifier body 1 and adjust its position using the four casters 204 at its bottom so that the suction nozzle 308 is aligned with the area where the laser marking smoke is generated. Then lock the braking structure of the casters 204 to prevent the device from shifting during operation. During the operation phase, start the purifier body 1. The device captures the smoke and dust generated in the marking area through the suction nozzle 308 and enters the purifier body 1 through the end pipe 301, suction pipe 203, and interface 202 for purification.
