Description

Technical Field

[0001] This utility model relates to the field of laser cutting equipment technology, and in particular to a laser cutting machine bed with partitioned dust extraction. Background Technology

[0002] Laser cutting machines are widely used in metal processing, electronics manufacturing, and industrial production, providing crucial support for modern manufacturing industries due to their high efficiency and precision. However, the laser cutting process often generates a large amount of smoke and particulate matter. If this is not removed in time, it can damage the equipment and affect cutting accuracy and the cleanliness of the production environment. To address this issue, current laser cutting machines typically control smoke and dust emissions by incorporating internal dampers and dust extraction systems.

[0003] Existing laser cutting machines mostly use sensors to control the opening and closing of dampers for automated dust extraction. While this design improves the system's automation level, allowing for flexible opening and closing of dampers based on the needs of the cutting area to achieve directional dust extraction and reduce energy consumption, the sensor control system is susceptible to environmental factors in practical use, especially in environments with high dust levels. For example, after prolonged use, the contacts of the sensor controller accumulate significant amounts of impurities and oil, leading to unstable signal transmission and affecting the damper's response speed and cutting efficiency. Furthermore, the accumulation of impurities shortens the sensor's lifespan, increasing equipment maintenance costs.

[0004] On the other hand, the worktable inside the laser cutting machine, as the core component supporting the workpiece, also becomes difficult to clean due to the accumulation of waste, debris and dust that fall during the cutting process. Especially in a closed or complex cutting environment, cleaning work requires frequent machine shutdowns, which reduces production efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a laser cutting machine bed with partitioned dust extraction, which aims to improve the problems of reduced response speed in existing laser cutting machines due to the susceptibility of sensor-controlled air dampers to impurity accumulation, and the difficulty in cleaning the internal worktable of the cutting machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A laser cutting machine bed with zoned dust extraction includes a frame, a cutting trolley mounted on the top of the frame, an air duct fixedly connected to the side wall of the frame, a lever fixedly connected to the bottom outer side of the cutting trolley, a movable block slidably connected to the outer wall of the air duct, a crossbar fixedly connected to the inner side of the movable block, a connecting rod rotatably connected to the other end of the crossbar, a crossbeam rotatably connected to the other end of the connecting rod, a frame fixedly connected to the inner wall of the air duct, a plurality of baffles rotatably connected to the middle of the frame, and the baffles rotatably connected to the bottom of the crossbeam.

[0008] As a further description of the above technical solution:

[0009] A fixed block is fixedly connected inside the air duct, and a spring is installed between the fixed block and the movable block.

[0010] As a further description of the above technical solution:

[0011] The frame is equipped with a partition plate, and a baffle is installed on the upper part of the partition plate;

[0012] As a further description of the above technical solution:

[0013] A material collection plate is slidably connected inside the frame, and the material collection plate is located below the partition plate;

[0014] As a further description of the above technical solution:

[0015] A shovel plate is slidably connected to the middle of the collecting plate, and a lever is fixedly connected to both ends of the shovel plate. A sliding groove is opened on the side wall of the collecting plate, and the lever is slidably connected to the middle of the sliding groove.

[0016] As a further description of the above technical solution:

[0017] The frame is equipped with a buckle on the outside, and the material collection plate is provided with a slot corresponding to the buckle on the outside.

[0018] As a further description of the above technical solution:

[0019] One side of the shovel plate is set as an inclined surface, and multiple sets of magnets are fixedly installed on the side of the shovel plate away from the inclined surface;

[0020] As a further description of the above technical solution:

[0021] Both ends of the movable block are provided with bevels, and the lever is in contact with the outer surface of the movable block.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, dust treatment is achieved through a partitioned dust extraction method using a mechanical structure. The movement of the cutting trolley drives the sliding of the lever to automatically open or close the baffle, avoiding the performance degradation problem caused by the accumulation of impurities in traditional sensor control. It can still maintain normal operation in high dust environments and after long-term use, greatly improving the stability and applicability of the equipment.

[0024] 2. In this utility model, the combined design of the collecting plate and the shovel plate not only makes it easy to collect and remove the falling slag, but also removes the slag adhering to the collecting plate by sliding the shovel plate, effectively reducing the difficulty and frequency of cleaning, and improving the ease of operation and cleaning efficiency of the equipment.

[0025] 3. In this utility model, by utilizing the cooperation between the baffle plate and the frame, as well as the partition design of the internal partition plate of the frame, the dust extraction system can accurately act on the laser cutting area, which greatly improves the dust extraction efficiency, reduces energy waste, and ensures the cleanliness near the cutting head, thereby improving the cutting quality and the overall working environment.

[0034] 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.

[0035] Reference Figures 1-4 This utility model provides an embodiment of a laser cutting machine bed with zoned dust extraction, including a frame 1. A cutting carriage 2 is mounted on the top of the frame 1. The cutting carriage 2 is driven by the laser cutting machine's own drive structure and can move freely horizontally on the upper part of the frame 1 to move the laser cutting head to cut the workpiece. This technology belongs to the prior art and will not be described in detail here. A duct 5 is fixedly connected to the side wall of the frame 1. A partition plate 3 is installed inside the frame 1. A baffle 4 is installed on the upper part of the partition plate 3. The open end of the duct 5 is connected to an external exhaust fan. The duct 5 is a hollow square pipe with multiple through holes on the side of the pipe near the middle of the frame 1. The position of these through holes corresponds to the area divided by the partition plate 3. A lever 6 is fixedly connected to the bottom outer side of the cutting carriage 2. When the cutting carriage 2 moves, it can drive the lever 6 to move synchronously. A movable block 7 is slidably connected to the outer wall of the duct 5. The movable block 7 is installed on the side of the duct 5 away from the center of the frame 1, and the movable block 7 penetrates the outer wall of the duct 5 and contacts the lever 6.

[0036] Reference Figures 3-4Both ends of the movable block 7 are provided with bevels, and the lever 6 is in contact with the outer surface of the movable block 7. When the lever 6 moves, it can reach the outside of the movable block 7 through the bevels, and then the movable block 7 moves into the air duct 5 by pressing the bevel surface with the lever 6. A crossbar 8 is fixedly connected to the inner side of the movable block 7. The other end of the crossbar 8 is rotatably connected to a connecting rod 9, and the other end of the connecting rod 9 is rotatably connected to a crossbeam 10. When the movable block 7 moves, it will drive the crossbar 8 to move synchronously, and drive the connecting rod 9 to rotate to a certain extent. A frame 12 is fixedly connected to the inner wall of the air duct 5. The frame 12 is installed on the side of the air duct 5 near the center of the frame 1. Multiple baffles 11 are rotatably connected to the middle of the frame 12. The gap between the baffles 11 and the frame 12 is adjusted by rotating the baffles 11, thereby adjusting the opening and closing of the air vent. The baffle plate 11 is rotatably connected to the bottom of the crossbeam 10. When the movable block 7 is pressed by the lever 6, the movable block 7 moves, causing the crossbeam 8 to move synchronously. At this time, under the action of the connecting rod 9, the crossbeam 10 is moved, thus causing the baffle plate 11 to rotate, thereby opening the air vent. In conjunction with the exhaust fan connected to the end of the air duct 5, the dust extraction operation during the cutting process is completed. A fixed block 13 is fixedly connected inside the air duct 5. A spring 14 is installed between the fixed block 13 and the movable block 7. When the movable block 7 is pressed by the lever 6, the spring 14 is also compressed and deformed. When the lever 6 moves out from the outside of the movable block 7, the spring 14 rebounds under its own deformation, which can push the movable block 7 back out to achieve reset, so as to carry out the next zone dust extraction operation.

[0037] Reference Figure 2 , Figure 5 and Figure 6 A collection plate 15 is slidably connected inside the frame 1, located below the partition plate 3. Molten slag generated during laser cutting falls downwards and is separated by the partition plate 3, landing on the upper surface of the collection plate 15. After a period of use, the collection plate 15 can be removed for cleaning to improve cleaning efficiency. Adding the collection plate 15 also reduces the internal space of the frame 1 to some extent, allowing the exhaust fan to generate greater air pressure and further improve dust extraction. A scraper plate 16 is slidably connected to the middle of the collection plate 15. When the collection plate 15 is removed from one side of the frame 1 for cleaning, the scraper plate 16 can be moved to scrape away the molten slag adhering to its surface and collect it for easier cleaning.

[0038] Reference Figures 5-6Both ends of the shovel plate 16 are fixedly connected to levers 18. The side wall of the collecting plate 15 has a sliding groove 17, and the levers 18 are slidably connected in the middle of the sliding groove 17. When cleaning the slag on the surface of the collecting plate 15, the shovel plate 16 can be slid along the sliding groove 17 simply by moving the levers 18. A buckle 20 is installed on the outside of the frame 1, and a corresponding slot is opened on the outside of the collecting plate 15. The buckle 20 is used to position the collecting plate 15, and after the collecting plate 15 is pushed into the frame 1, it prevents the collecting plate 15 from shaking.

[0039] Reference Figure 5 The shovel plate 16 has a sloping side on one side, and multiple sets of magnets 19 are fixedly installed on the side of the shovel plate 16 away from the sloping side. The shovel plate 16 can be attracted to the inner wall of the collecting plate 15 by the magnets 19. When the collecting plate 15 is assembled inside the frame 1, the magnets 19 can ensure the stability of the position of the shovel plate 16, so as to ensure that the molten slag generated by cutting falls on the working side of the shovel plate 16.

[0040] Working Principle: When using this laser cutting machine, the workpiece to be cut is placed on the upper part of the baffle 4 and positioned. Then, the cutting head moves by driving the cutting carriage 2 to cut the workpiece, generating a large amount of smoke and dust during the cutting process. Simultaneously, the moving carriage 2 moves the lever 6, which slides on the outer surface of the air duct 5. When the lever 6 slides to the position of the movable block 7, the inclined surface at the end of the movable block 7 causes it to move inwards towards the air duct 5. The movable block 7 then acts on the crossbar 8, causing the connecting rod 9 to move synchronously. When the connecting rod 9 moves, its other end is connected to the crossbeam 10, which in turn connects to one end of multiple baffle plates 11. This allows the baffle plates 11 to rotate along the frame 12. When the air baffle 11 is opened, a gap is created between it and the frame 12. The open end of the air duct 5 is connected to an external exhaust fan. At this time, the smoke and dust generated by the laser cutting head enters the air duct 5 through the gap between the air baffle 11 and the frame 12, and is then extracted through the air duct 5. This completes the smoke and dust treatment operation. This function is implemented using a purely mechanical structure and is not affected by smoke and dust. Even after long-term use and in environments with a lot of smoke and dust, it can still operate normally, which greatly improves the application environment and service life of the laser cutting machine and makes it more convenient to use.

[0041] After the cutting trolley 2 moves and causes the lever 6 to move out of the outside of a movable block 7, the spring 14 rebounds and pushes the movable block 7 out again. This drives the crossbar 8 and connecting rod 9 to reset. The baffle 11 also closes with the frame 12 under the action of the crossbeam 10. This, together with the partition plate 3 inside the frame 1, enables zoned dust extraction to improve the dust extraction effect.

[0042] During workpiece cutting, smaller fumes are discharged through duct 5, while larger molten slag falls downwards and is collected by the collecting plate 15. After a period of use, the collecting plate 15 is moved by opening the latch 20, and then it can be pulled out from one side of the frame 1, bringing out the molten slag on the upper part of the collecting plate 15. Then, the pry bar 18 on both sides of the collecting plate 15 drives the shovel plate 16, so that the shovel plate 16 slides on the upper surface of the collecting plate 15 to collect the molten slag on the upper surface of the collecting plate 15 and remove the molten slag adhering to the surface of the collecting plate 15. This facilitates the cleaning of these impurities. After cleaning, the shovel plate 16 is reset, and the magnet 19 can make the shovel plate 16 re-adhere to the inner wall of one side of the collecting plate 15. This ensures that the molten slag is cleaned and falls to the working side of the shovel plate 16.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
