Technical Field
[0001] This utility model relates to the field of laser cutting technology, and more specifically, it relates to a dust collection and smog guide for a laser cutting machine. Background Technology
[0002] In the field of laser cutting, laser cutting machines are widely used in metal processing, automotive manufacturing, aerospace, and many other industries due to their high precision and efficiency. However, the laser cutting process generates a large amount of fumes, which not only contain harmful substances such as metal particles and oxides, posing serious health risks to operators (such as respiratory illnesses and eye damage), but also permeate the workshop, polluting the production environment, affecting the normal operation and lifespan of equipment, and potentially causing safety accidents such as fires. Therefore, the effective collection and treatment of fumes generated during laser cutting is crucial.
[0003] Currently, most dust removal equipment for laser cutting machines on the market uses a combination of a bottom negative pressure suction system and a top fixed hood dust collection device to handle the dust generated during laser cutting. The bottom negative pressure suction system typically has a negative pressure suction port installed below the laser cutting machine's worktable. A fan generates negative pressure to suck away the dust generated during the cutting process from below. The top fixed hood dust collection device is a fixed dust collection hood installed above the laser cutting machine. The fan uses suction to draw the rising dust into the hood for processing.
[0004] However, this traditional method of fume treatment has many drawbacks. On the one hand, the bottom negative pressure suction system requires the construction of complex ventilation ducts and negative pressure generating devices under the workbench, and the top fixed hood dust collection device also requires a high-powered fan and a large dust collection space, which makes the equipment cost of the entire fume treatment system high and increases the company's production investment. On the other hand, due to the fixed structure of the ventilation ducts of the bottom negative pressure suction system and the top fixed hood dust collection device, precise positioning and complex connections are required during installation, making installation difficult and time-consuming; moreover, subsequent inspection and maintenance require disassembly and inspection of the entire system, which is cumbersome, time-consuming, and labor-intensive, seriously affecting production efficiency. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dust collection hood for a laser cutting machine that can be installed next to the laser cutting machine.
[0006] To achieve the above objectives, the present invention provides the following technical solution: This utility model is further configured as follows: it includes a housing and a laser cutting device disposed on the top of the housing. The dust collection hood of the laser cutting device also includes a dust collection mechanism. The dust collection mechanism is disposed on the side of the laser cutting device. The dust collection mechanism includes a dust collection hood, a rotating part, and a displacement part. The dust collection hood is disposed on the side of the laser cutting device. The rotating part is rotatably disposed on the side of the laser cutting device, and the end of the rotating part is connected to the end of the dust collection hood. When the rotating part rotates, it can drive the dust collection hood to flip. The displacement part is vertically slidably disposed on the side of the laser cutting device, and the bottom of the displacement part is connected to the end face of the rotating part. When the displacement part moves, it can drive the rotating part and the dust collection hood to move synchronously.
[0007] By adopting the above technical solution, the problem of excessively high cost of bottom negative pressure suction system and top fixed cover dust collection device in the existing technology is solved, achieving the effect of low-cost and high-efficiency collection and purification of laser cutting smoke and dust, while significantly reducing the difficulty of equipment deployment and maintenance.

[0011] The present invention is further configured such that: the dust collection mechanism also includes a rotary motor; the rotary motor is located on the side of the positioning plate, and the output end of the rotary motor is connected to the first rotating part, so that when the rotary motor is started, it can drive the first rotating part to rotate.
[0012] The present invention is further configured such that: the displacement part is a cylindrical structure, and the displacement part and the limiting part are fitted with a clearance.
[0013] In summary, this application includes at least one of the following beneficial technical effects: By setting up a dust collection mechanism, the problem of excessively high costs of bottom negative pressure suction systems and top fixed cover dust collection devices in existing technologies is solved, achieving the effect of low-cost and high-efficiency collection and purification of laser cutting dust.

[0015] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0016] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0017] Please see Figure 1-6 The present invention provides the following technical solution: Example 1 addresses the problem that existing technologies commonly employ bottom negative pressure suction systems and top fixed cover dust collection devices for dust treatment, which result in high operating costs and time-consuming and labor-intensive installation and maintenance processes.
[0018] The device includes a housing 1 and a laser cutting device 2 mounted on top of the housing 1. The dust collection hood of the laser cutting device 2 also includes a dust collection mechanism 3. The dust collection mechanism 3 is located beside the laser cutting device 2. The dust collection mechanism 3 includes a dust collection hood 31, a rotating part 32, and a displacement part 33. The dust collection hood 31 is located beside the laser cutting device 2. The rotating part 32 is rotatably mounted beside the laser cutting device 2, and its end is connected to the end of the dust collection hood 31. When the rotating part 32 rotates, it can drive the dust collection hood 31 to flip. The displacement part 33 is vertically slidably mounted beside the laser cutting device 2, and its bottom is connected to the end face of the rotating part 32. When the displacement part 33 moves, it can drive the rotating part 32 and the dust collection hood 31 to move synchronously.
[0019] A dust collector is installed beside the laser cutting device 2 to purify the smoke and dust. The suction end of the dust collector is tightly connected to the smoke collection hood 31. When the dust collector is activated, it can collect and purify the smoke and dust generated during the operation of the laser cutting device 2 through the smoke collection hood 31. To address the position adjustment requirements of the smoke collection hood 31, this embodiment uses a rotating part 32 drive mechanism to control its horizontal displacement. When the rotating part 32 rotates, it can move the smoke collection hood 31 closer to or further away from the working area of the laser cutting device 2, ensuring that the two maintain synchronous movement. The smoke collection hood 31 is made of stainless steel and is flexibly connected to the dust collector via a bamboo-joint tube. To achieve timely collection of diffused smoke and dust, when the displacement part 33 moves linearly, it can simultaneously drive the rotating part 32 and the smoke collection hood 31 to move up and down. This achieves position adjustment of the smoke collection hood 31, effectively solving the problem of excessively high costs associated with bottom negative pressure suction systems and top fixed-hood dust collection devices in existing technologies, achieving low-cost and efficient collection and purification of laser cutting smoke and dust.
[0020] See Figures 2-5 The dust collection mechanism 3 also includes a mounting plate 34 and a rotary cylinder 35; the mounting plate 34 is located at the bottom of the displacement part 33; the rotary cylinder 35 is located at the bottom of the mounting plate 34, and the output end of the rotary cylinder 35 is connected to the rotating part 32. When the displacement part 33 moves, the mounting plate 34 can drive the rotary cylinder 35 and the rotating part 32 to move synchronously.
[0021] When the displacement part 33 moves, it can drive the mounting plate 34, the rotary cylinder 35 and the rotating part 32 to move synchronously upward or downward, thereby adjusting the position between the dust collection hood 31 and the laser cutting device 2, and preventing the problem of smoke diffusion after the laser cutting device 2 cuts.
[0022] See Figures 3-5The dust collection mechanism 3 also includes a positioning plate 36 and a limiting part 37; the positioning plate 36 is set on the side of the laser cutting device 2 by fasteners; the limiting part 37 is set on the side of the positioning plate 36, and the end of the limiting part 37 is provided with a circular slot for limiting the sliding of the displacement part 33.
[0023] In order to enable the displacement part 33 to move stably upward and downward, the displacement part 33 can first slide stably through the circular slot in the middle of the limiting part 37 when it moves, thereby enabling the dust collection hood 31 to move stably.
[0024] See Figure 5 and Figure 6 The dust collection mechanism 3 also includes a first rotating part 38, a hinge part 39, and a setting part 391. The first rotating part 38 is rotatably disposed on the side of the positioning plate 36. The hinge part 39 is rotatably disposed on the end face of the first rotating part 38 and is located on the side of the positioning plate 36. The setting part 391 is rotatably mounted on the right side of the hinge part 39 and is rotatably connected to the displacement part 33. When the first rotating part 38 rotates, the displacement part 33 can be driven to move in a vertical direction through the rotatably connected hinge part 39 and setting part 391.
[0025] In order to drive the displacement part 33 to rise and fall, the first rotating part 38 first rotates. When the first rotating part 38 rotates, it can drive the hinge part 39 to rotate. When the hinge part 39 rotates, it can drive the setting part 391 and the displacement part 33 to move steadily up and down along the limiting part 37.
[0026] See Figure 6 The dust collection mechanism 3 also includes a rotary motor 392; the rotary motor 392 is located on the side of the positioning plate 36, and the output end of the rotary motor 392 is connected to the first rotating part 38. When the rotary motor 392 is started, it can drive the first rotating part 38 to rotate.
[0027] In this embodiment, the rotary motor 392 is preferably a servo motor, which can drive the first rotating part 38 to rotate when the rotary motor 392 is started.
[0028] See Figures 4-6 The displacement part 33 has a cylindrical structure, and there is a clearance fit between the displacement part 33 and the limiting part 37.
[0029] In this embodiment, the displacement part 33 is preferably a cylindrical structure, and when the displacement part 33 moves, it can move along the clearance fit restriction part 37.
[0030] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
