Description

Technical Field

[0001] This utility model relates to the field of laser cladding equipment technology, specifically a laser cladding equipment with built-in dust removal. Background Technology

[0002] Laser cladding technology uses a high-energy laser beam to melt metal powder onto the surface of a substrate, forming a metallurgical bonding layer. This significantly improves the wear resistance and corrosion resistance of workpieces and has been widely used in high-end manufacturing. However, the process generates a large amount of metal fumes, unmelted powder, and splash cooling dust. These pollutants not only contaminate the working environment and harm the respiratory health of operators, but also easily adhere to the optical lenses of the laser head, causing laser energy attenuation and reduced focusing accuracy. This can lead to defects such as porosity and cracks in the cladding layer, and even cause the lenses to shatter. At the same time, dust accumulated on the worktable surface mixes into the subsequent cladding powder, which can damage the metallurgical stability of the molten pool and reduce the bonding strength between the coating and the substrate.

[0003] Existing dust removal solutions for laser cladding equipment are mainly divided into two categories: external and internal, both of which have significant drawbacks. Among them, the core shortcoming of internal dust removal equipment lies in the extremely cumbersome filter replacement operation: its filtration system mostly adopts a fixed encapsulation structure, with the filter embedded in the dust removal chamber inside the equipment. When replacing it, multiple components such as the workbench guard plate and dust removal pipes must be disassembled in sequence. The operation process is complicated, seriously interrupting the continuity of production. Moreover, the disassembly process can easily cause the dust accumulated in the chamber to be re-entrained, causing internal pollution of the equipment.

[0004] In view of this, a laser cladding device with built-in dust removal is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The purpose of this invention is to provide a laser cladding device with built-in dust removal to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a laser cladding device with built-in dust removal, including a worktable and an air inlet. An air outlet and an air inlet are fixedly installed on the top surface of the worktable. A collector pipe is fixedly connected to the rear end of both the air outlet and the air inlet. A first fan is fixedly connected to the other side of the collector pipe connected to the rear end of the air inlet. A limiting groove is formed in the middle of the bottom of the worktable. A movable first filter plate is arranged inside the limiting groove. In the initial state, the first filter plate is located inside the limiting groove. A snap-fit ​​groove is formed at the edge of the first filter plate. A movable moving block is arranged on the side wall of the limiting groove. The edge of the moving block near the limiting groove is inclined. A spring pull plate is fixedly connected to one end of the moving block. A return spring is fixedly connected between the spring pull plate and the worktable. In this initial state, the moving block is located inside the snap-fit ​​groove.

[0007] Furthermore, multiple sealing plates are installed in the middle of the workbench, and the multiple sealing plates together form a sealed box. The end of the first fan near the middle of the workbench is connected to the top surface of the sealing plate at the top of the sealed box through a manifold.

[0008] Furthermore, there are two limiting grooves, which are arranged symmetrically. The first filter plate is located inside the upper limiting groove, and a movable second filter plate is located inside the lower limiting groove. The side wall of the second filter plate is also provided with a snap-fit ​​groove.

[0009] Furthermore, the specific number of the moving blocks is four, and the positions of the four moving blocks correspond to the first filter plate and the second filter plate, respectively.

[0010] Furthermore, a second fan is fixedly connected to the other side of the manifold at the rear end of the air outlet. The second fan is located at the bottom of the sealed box and is connected to the middle position of the bottom of the sealed box through the manifold.

[0011] Furthermore, filter screen pull plates are fixedly installed on the side walls of both the first and second filter plates.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By incorporating a moving block and spring pull plate, users can quickly and smoothly disassemble the first and second filter plates, and easily and quickly clean and replace them.

[0013] By simultaneously setting up air inlets and outlets, the air inlets and outlets can form an air duct together, allowing dust that is difficult to be blown away under normal conditions to be collected by the device, thus increasing the applicability and practicality of the device.

[0016] 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.

[0017] See Figure 1-4 A laser cladding device with built-in dust removal includes a worktable 1 and an air inlet 2. An air outlet 5 and an air inlet 2 are fixedly installed on the top surface of the worktable 1. A collection pipe 3 is fixedly connected to the rear end of both the air outlet 5 and the air inlet 2. A first fan 4 is fixedly connected to the other side of the collection pipe 3 connected to the rear end of the air inlet 2. A limiting groove 14 is opened in the middle of the bottom of the worktable 1. A movable first filter plate 7 is arranged inside the limiting groove 14. The first filter plate 7 is initially located inside the limiting groove 14. A snap-fit ​​groove 9 is opened at the edge of the first filter plate 7. A movable moving block 11 is arranged on the side wall of the limiting groove 14. The edge of the moving block 11 near the limiting groove 14 is inclined. A spring pull plate 13 is fixedly connected to one end of the moving block 11. A return spring 12 is fixedly connected between the spring pull plate 13 and the worktable 1. The moving block 11 is initially located inside the snap-fit ​​groove 9.

[0018] Furthermore, multiple sealing plates are installed in the middle of the interior of the workbench 1. These multiple sealing plates together form a sealed box. The end of the first fan 4 near the middle of the workbench 1 is connected to the top surface of the sealing plate at the top of the sealed box through the manifold 3. The other side of the manifold 3 at the rear end of the air outlet 5 is fixedly connected to a second fan 6. The second fan 6 is located at the bottom of the sealed box and is connected to the middle of the bottom of the sealed box through the manifold 3.

[0019] By setting up a sealed enclosure, and by connecting one end of the first fan 4 near the middle of the workbench 1 to the top surface of the sealing plate at the top of the sealed enclosure via a manifold 3, and fixing the other side of the manifold 3 at the rear end of the outlet 5 with a second fan 6, the second fan 6 is located at the bottom of the sealed enclosure. This allows the first fan 4 and the second fan 6 to draw air into the device from the inlet 2 after starting, and to suck in dust during the air extraction process, which is then transported into the interior of the sealed enclosure and filtered by the first filter plate 7 and the second filter plate 8. After the second fan 6 starts, it blows the filtered air through the outlet 5 onto the top surface of the workbench 1 and pushes the air toward the opening of the inlet 2, so that heavier dust that cannot be easily sucked in by the inlet 2 can be sucked into the interior of the sealed enclosure by the combined action of the first fan 4 and the second fan 6.

[0020] Furthermore, there are two limiting grooves 14, which are arranged symmetrically. The first filter plate 7 is located inside the upper limiting groove 14, and a movable second filter plate 8 is located inside the lower limiting groove 14. The side wall of the second filter plate 8 is also provided with a snap-fit ​​groove 9.

[0021] In addition, there are four movable blocks 11, and the positions of the four movable blocks 11 correspond to the first filter plate 7 and the second filter plate 8 respectively. Filter screen pull plates 10 are fixedly installed on the side walls of the first filter plate 7 and the second filter plate 8.

[0022] By setting the filter pull plate 10, users can more easily remove the first filter plate 7 and the second filter plate 8 from the limiting groove 14. The positions of the four moving blocks 11 correspond to the first filter plate 7 and the second filter plate 8, respectively, so that the movement of the first filter plate 7 and the second filter plate 8 is restricted by the moving blocks 11.

[0023] In practice, conventional built-in dust removal devices are difficult to replace during use, and the dust adhering to the filter screen is easily dispersed again during the replacement process.

[0024] In this practical application, when the user is performing vacuuming work, the first fan 4 and the second fan 6 can be started first. After the first fan 4 and the second fan 6 are started, they can draw air into the device from the air inlet 2. During the air extraction process, the dust is sucked in and transported to the inside of the sealed box and filtered by the first filter plate 7 and the second filter plate 8. After the second fan 6 is started, the filtered air will be blown to the top surface of the workbench 1 through the air outlet 5 and pushed towards the opening of the air inlet 2. This allows the heavier dust that cannot be easily sucked in by the air inlet 2 to be sucked into the inside of the sealed box by the combined action of the first fan 4 and the second fan 6.

[0025] During the vacuuming process, dust will continuously adhere to the surfaces of the first filter plate 7 and the second filter plate 8. At this time, simply pull the spring pull plate 13 to move the moving block 11. When one side of the moving block 11 moves out of the snap-fit ​​groove 9 inside the first filter plate 7 and the second filter plate 8, the movement of the first filter plate 7 and the second filter plate 8 is no longer restricted. They can be easily and smoothly removed from the limiting groove 14 and processed.

[0026] During installation, simply push the first filter plate 7 and the second filter plate 8 into the limiting groove 14. The edges of the first filter plate 7 and the second filter plate 8 will abut against the inclined surface of the moving block 11, causing the moving block 11 to move in a predetermined direction. This allows the first filter plate 7 and the second filter plate 8 to be reset smoothly. After the first filter plate 7 and the second filter plate 8 are reset, the moving block 11 will be inserted back into the snap-fit ​​groove 9 under the elastic force of the reset spring 12 to limit the first filter plate 7 and the second filter plate 8, preventing them from easily separating.

[0027] By setting the movable block 11 and the spring pull plate 13, users can quickly and smoothly disassemble the first filter plate 7 and the second filter plate 8, and can quickly and easily clean and replace the first filter plate 7 and the second filter plate 8.

[0028] It should be noted that the inner diameters of the filter holes inside the first filter plate 7 and the second filter plate 8 are different. The inner diameter of the filter holes in the upper first filter plate 7 is larger than that in the lower second filter plate 8. This arrangement allows dust of different sizes to be filtered and collected by the first filter plate 7 and the second filter plate 8 respectively.

[0029] In addition, it should be noted that the first fan 4 and the second fan 6 blow air in opposite directions. At the same time, square blocks that fit into the limiting grooves 14 are provided at the edges of the first filter plate 7 and the second filter plate 8. The presence of the square blocks allows the first filter plate 7 and the second filter plate 8 to be stably placed inside the two limiting grooves 14.

[0030] By simultaneously setting up an air inlet 2 and an air outlet 5, the dust inlet and the air outlet 5 can form an air duct together, allowing dust that is difficult to be blown away under normal conditions to be collected by the device smoothly, thus increasing the applicability and practicality of the device.

[0031] Working principle: Conventional built-in dust collectors are difficult to replace during use, and the dust attached to the filter is easily dispersed again during the replacement process.

[0032] In this practical application, when the user is performing vacuuming work, the first fan 4 and the second fan 6 can be started first. After the first fan 4 and the second fan 6 are started, they can draw air into the device from the air inlet 2. During the air extraction process, the dust is sucked in and transported to the inside of the sealed box and filtered by the first filter plate 7 and the second filter plate 8. After the second fan 6 is started, the filtered air will be blown to the top surface of the workbench 1 through the air outlet 5 and pushed towards the opening of the air inlet 2. This allows the heavier dust that cannot be easily sucked in by the air inlet 2 to be sucked into the inside of the sealed box by the combined action of the first fan 4 and the second fan 6.

[0033] During the vacuuming process, dust will continuously adhere to the surfaces of the first filter plate 7 and the second filter plate 8. At this time, simply pull the spring pull plate 13 to move the moving block 11. When one side of the moving block 11 moves out of the snap-fit ​​groove 9 inside the first filter plate 7 and the second filter plate 8, the movement of the first filter plate 7 and the second filter plate 8 is no longer restricted. They can be easily and smoothly removed from the limiting groove 14 and processed.

[0034] During installation, simply push the first filter plate 7 and the second filter plate 8 into the limiting groove 14. The edges of the first filter plate 7 and the second filter plate 8 will abut against the inclined surface of the moving block 11, causing the moving block 11 to move in a predetermined direction. This allows the first filter plate 7 and the second filter plate 8 to be reset smoothly. After the first filter plate 7 and the second filter plate 8 are reset, the moving block 11 will be inserted back into the snap-fit ​​groove 9 under the elastic force of the reset spring 12 to limit the first filter plate 7 and the second filter plate 8, preventing them from easily separating.

[0035] By setting the movable block 11 and the spring pull plate 13, users can quickly and smoothly disassemble the first filter plate 7 and the second filter plate 8, and can quickly and easily clean and replace the first filter plate 7 and the second filter plate 8.

[0036] By simultaneously setting up air inlet 2 and air outlet 5, the air inlet 2 and air outlet 5 can together form an air duct, so that dust that is difficult to be blown away under normal conditions can be successfully collected by the device, increasing the applicability and practicality of the device.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
