Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, specifically to an integrated laser cutting device for dust removal and noise reduction. Background Technology

[0002] Laser cutting technology, with its high precision and efficiency, is widely used in various industrial production fields such as metal processing and automobile manufacturing. It achieves rapid and precise cutting of workpieces through the high energy density of the laser beam, meeting the processing needs of workpieces of different specifications. However, in actual industrial applications, existing laser cutting equipment still has many technical pain points that urgently need to be addressed, seriously affecting processing quality, operating environment, and equipment lifespan.

[0003] Laser cutting generates a large amount of fumes containing heavy metal particles and organic pollutants. Existing laser cutting equipment often uses a single dust collection structure, making it difficult to synchronize the position of the dust collection port with the cutting point, resulting in blind spots in dust collection. Furthermore, the dust collection channel is prone to blockage due to dust adhesion, requiring frequent manual cleaning, which is difficult and costly to maintain. Although some equipment is equipped with a dust collection structure, it cannot capture dust at the source, making it difficult to achieve a comprehensive and effective dust collection effect. Since there may be floating dust and debris on the surface of the workpiece, these impurities will cause laser energy scattering during laser cutting, resulting in edge burning at the cutting edge, affecting the surface finish of the workpiece and reducing product quality.

[0004] Therefore, it is urgent to improve the aforementioned equipment in order to solve the problems mentioned above. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an integrated laser cutting equipment for dust removal and noise reduction. It features high efficiency, thorough dust removal, and protection against clogging and burning. Through multi-structure collaborative linkage, it achieves simultaneous air blowing for dust removal, tapping to prevent clogging, dual dust removal, and precise cutting, significantly improving cutting accuracy and dust removal and noise reduction efficiency. This results in the excellent integration and intelligent operation of laser processing and environmental protection.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated dust removal and noise reduction laser cutting device, comprising a body, a laser cutter disposed on the surface of the body, a first collection mechanism disposed inside the body, and a second collection mechanism disposed outside the laser cutter.

[0011] Furthermore, a transmission block is fixedly connected to the bottom side of the piston cylinder, and an inclined groove for forward and backward transmission is opened inside the transmission block. A roller extending into the inclined groove is hinged to one side of the outside of the moving plate, and the inclined groove and the roller are in a rolling connection.

[0012] Furthermore, the second collection mechanism includes a collection box disposed outside the laser cutter and an annular suction tube fixedly connected to the inner wall of the protective cover. A second negative pressure fan is rotatably connected inside the collection box, and a conveying pipe is fixedly connected between the collection box and the second negative pressure fan. A collection plate is slidably connected inside the collection box.

[0013] Furthermore, the striking structure includes a linkage plate fixedly connected to the outside of the moving plate and a moving ring fixedly connected to one side of the linkage plate. A rubber block that abuts against the surface of the annular straw is fixedly connected to the bottom side of the moving ring. The moving ring and the rubber block are reciprocally slidably connected to the surface of the annular straw through the moving plate.

[0014] Furthermore, the first collection mechanism includes a collection hopper fixedly connected to the inside of the machine body, an installation box fixedly connected to one side of the machine body, a first negative pressure fan rotatably installed inside the installation box, and a filter plate slidably connected inside the installation box.

[0016] Compared with the prior art, the present invention provides an integrated laser cutting device for dust removal and noise reduction, which has the following beneficial effects: 1. In this invention, the protective cover is supported by a ball bearing and adheres tightly to the surface of the plate. When the movable sleeve extends and retracts, the pin shaft is driven in the spiral groove, which drives the rotating column to rotate. The inclined platform rotates accordingly and drives the piston cylinder to reciprocate, so that the exhaust pipe blows air in front of the cutting path, which cleans up the floating dust and debris in time, improves the laser energy concentration and the surface finish, reduces the risk of edge burning, and improves the cutting quality.

[0017] 2. In this invention, during the reciprocating motion of the piston cylinder, not only is high-pressure airflow output through the exhaust pipe, but an elastic squeezing action is also formed between the abutment plate and the outer surface of the mounting cylinder. This squeezing will generate a periodic impact force on the outside of the protective cover, causing the protective cover to vibrate slightly, effectively preventing smoke, dust, debris, and slag from adhering to the inner wall, avoiding blockage of the air intake, and thus continuously and stably improving the dust removal efficiency.

[0018] 3. In this invention, when the moving plate slides up and down, it drives the linkage plate and the moving ring to move synchronously. The rubber block at the bottom of the moving ring repeatedly strikes the annular suction tube. Combined with the high-frequency airflow impact of the piston structure, the dual action effectively removes the dust accumulated on the inner wall of the annular suction tube, ensuring stable air extraction by the second negative pressure fan. It quickly captures smoke and dust near the cutting point from the source, achieving efficient dust removal and reducing the risk of edge burning.

[0019] 4. In this invention, the second collection mechanism captures nearby smoke and dust using a ring-shaped suction pipe, while the first collection mechanism receives falling dust and debris through a collection hopper, which is then transported to the installation box via a guide pipe. The dust is then extracted by the first negative pressure fan and filtered through a filter plate. The dual collection structure works in tandem, enabling the equipment to capture both source smoke and dust and clean up scattered dust, thereby improving the overall dust removal and noise reduction capabilities.

[0020] 5. This invention, by moving the laser cutter, drives the contact structure and the follow-up piston structure to operate synchronously, thus completing the three functions of air blowing, knocking, and chip removal. Simultaneously, the electric guide rail and electric slide table drive the laser cutter to move in three dimensions, with the collection box following synchronously, ensuring that the dust removal structure is always aligned with the cutting point. This allows the equipment to effectively remove dust and reduce noise at different cutting positions, prevent edge burning, and ensure stable cutting. Attached Figure Description

[0027] To achieve the effects of blocking cutting fumes and noise, providing power for subsequent linkage structures, and reducing equipment energy consumption, please refer to [link to relevant documentation]. Figures 3 to 6 In this embodiment, the abutment structure 5 includes a connecting frame 51 fixedly connected to the outside of the laser cutter 2, a protective cover 52 fixedly connected to the bottom side of the connecting frame 51, and a mounting cylinder 53 fixedly connected to the outside of the protective cover 52. A rotating column 54 is rotatably connected inside the mounting cylinder 53. A movable sleeve 56 extending to its bottom side is slidably connected inside the mounting cylinder 53. A ball 57 is fixedly connected to the bottom side of the movable sleeve 56. A spiral groove 55 is opened inside the rotating column 54. A pin 59 extending into the spiral groove 55 is fixedly connected to the inner wall of the movable sleeve 56. A ramp 510 is fixedly connected to the top of the rotating column 54. By setting up a protective cover 52, a local enclosed space can be formed around the cutting point to block smoke and noise. The rolling ball 57 can assist the protective cover 52 to move smoothly along the workpiece surface, reducing friction damage. The moving sleeve 56 and the rotating column 54 are linked through the pin 59 and the spiral groove 55, which converts the linear extension and retraction of the moving sleeve 56 into the rotational motion of the rotating column 54, providing power for the subsequent follow-up piston structure 6 and the striking structure 7, realizing mechanical linkage without additional power and reducing energy consumption.

[0028] Specifically, the movable sleeve 56 is slidably connected to the inside of the mounting cylinder 53, and a limit ring is fixedly connected to the outside of the movable sleeve 56. The outer diameter of the movable sleeve 56 is matched with the inner diameter of the mounting cylinder 53.

[0029] It should be noted that an abutment spring 58 is fixedly connected to the inner bottom wall of the movable sleeve 56, and a transmission groove adapted to the abutment spring 58 is opened inside the rotating column 54. The top of the abutment spring 58 is rotatably connected to the inner top wall of the transmission groove, and the inclined platform 510 is rotatably connected to the surface of the mounting cylinder 53. The abutment spring 58 can realize the automatic reset of the movable sleeve 56, ensuring that the ball 57 is always tightly attached to the workpiece surface, adapting to workpieces with different flatness, and preventing the protective cover 52 from loosening due to the undulation of the workpiece surface. At the same time, the abutment spring 58 cooperates with the transmission groove to assist the rotating column 54 to rotate smoothly, ensuring the smooth rotation of the inclined platform 510, and providing continuous and stable power support for the subsequent movement of the movable plate 611.

[0030] To achieve the effects of active cleaning protective cover 52, pre-cleaning workpiece dust to prevent cutting edge burning and improve the surface finish, please refer to... Figures 4 to 7 In this embodiment, the follower piston structure 6 includes a guide rod 61 fixedly connected to the outside of the protective cover 52, a sliding sleeve 62 slidably connected to the outside of the guide rod 61, and a piston cylinder 63 fixedly connected to the outside of the sliding sleeve 62. A piston rod 64 extending to the outside of the piston cylinder 63 is slidably connected inside the piston cylinder 63. An abutment plate 65 is fixedly connected to the end of the piston rod 64 away from the piston cylinder 63. A return spring 66 is fixedly connected between the abutment plate 65 and the piston cylinder 63. Check valves 67 are fixedly connected to both the upper and lower sides of the piston cylinder 63. An exhaust pipe 68 is fixedly connected to the inside of the bottom check valve 67. The follow-up piston structure 6 can realize the dual functions of blowing and striking. During operation, the piston cylinder 63 reciprocates and blows air in front of the cutting path through the exhaust pipe 68 to clean the floating dust and debris on the surface of the workpiece in advance, avoid the floating dust from causing laser energy scattering, prevent the cutting edge from burning, and improve the surface finish. At the same time, the piston rod 64 drives the abutment plate 65 to periodically strike the outside of the protective cover 52 to achieve active cleaning, prevent smoke and dust from adhering to the inner wall of the protective cover 52, and avoid clogging the dust suction channel.

[0031] The abutment plate 65 is located on the outer surface of the mounting cylinder 53, the return spring 66 is connected to the outside of the piston rod 64, the top check valve 67 is internally connected to the air inlet pipe 69, and the exhaust pipe 68 is located on one side outside the protective cover 52. The piston rod 64 consists of a piston block and a stopper rod. The return spring 66 can drive the piston rod 64 to automatically return to its original position, ensuring that the piston cylinder 63 continuously and stably performs reciprocating motion and ensuring smooth blowing action. The air inlet pipe 69 cooperates with the check valve 67 to achieve unidirectional airflow, ensuring that the piston cylinder 63 inhales and blows air in an orderly manner. The exhaust pipe 68 faces the cutting path outside the protective cover 52, which can accurately blow away floating dust. The abutment plate 65 fits against the surface of the mounting cylinder 53, ensuring that the impact force is effectively transmitted to the protective cover 52, improving the active cleaning effect.

[0032] Specifically, a limiting rod 610 is fixedly connected to the top of the mounting cylinder 53. A movable plate 611 is slidably connected to the outside of the limiting rod 610. A tension spring 612 is fixedly connected between the movable plate 611 and the mounting cylinder 53, and the tension spring 612 is wrapped around the outside of the limiting rod 610. An abutting cylinder 613 is fixedly connected inside the movable plate 611, abutting against the surface of the inclined platform 510. The movable plate 611 is slidably connected to the surface of the mounting cylinder 53 through the abutting cylinder 613. By setting the limiting rod 610, the sliding direction of the movable plate 611 can be restricted, preventing the movable plate 611 from deviating and causing linkage failure. The tension spring 612 realizes the automatic reset of the movable plate 611, ensuring that the movable plate 611 is always in close contact with the inclined platform 510. The abutting cylinder 613 can reduce the friction between the movable plate 611 and the inclined platform 510, smoothly converting the rotational motion of the rotating column 54 into the up and down sliding motion of the movable plate 611, realizing the precise linkage between the abutting structure 5 and the follower piston structure 6, and ensuring the coordinated operation of the overall structure.

[0033] It should be noted that a transmission block 614 is fixedly connected to the bottom side of the piston cylinder 63. The transmission block 614 has an inclined groove 615 inside for forward and backward transmission. A roller 616 extending into the inclined groove 615 is hinged to one side of the outer side of the moving plate 611. The inclined groove 615 and the roller 616 are in a rolling connection. By setting the roller 616 and the inclined groove 615 in a rolling connection, the frictional resistance during transmission is significantly reduced, component wear is decreased, and the service life of the equipment is extended. Simultaneously, the up-and-down sliding of the moving plate 611 can be smoothly converted into the forward and backward movement of the piston cylinder 63, ensuring smooth operation of the piston cylinder 63 and making the blowing and striking actions synchronous and stable, further improving the active cleaning and edge-burning prevention effects.

[0034] To achieve automatic cleaning of the annular suction tube 43, prevent clogging, and ensure the dust removal efficiency of the second collection mechanism 4, please refer to [link / reference needed]. Figure 5 and Figure 7 In this embodiment, the striking structure 7 includes a linkage plate 71 fixedly connected to the outside of the moving plate 611 and a moving ring 72 fixedly connected to one side of the linkage plate 71. A rubber block 73 is fixedly connected to the bottom side of the moving ring 72, which abuts against the surface of the annular suction tube 43. The moving ring 72 and the rubber block 73 are connected to the surface of the annular suction tube 43 by the reciprocating sliding of the moving plate 611. The striking structure 7 is linked with the moving plate 611 to realize automatic striking. When the moving plate 611 slides, it drives the linkage plate 71 and the moving ring 72 to reciprocate synchronously. The rubber block 73 periodically strikes the annular suction tube 43, which can actively remove the smoke and dust attached to the inner wall of the annular suction tube 43, prevent the suction tube from being blocked, and ensure the smoke and dust extraction efficiency of the second collection mechanism 4. At the same time, the rubber block 73 is soft and can avoid damaging the annular suction tube 43 by striking, thus improving the service life of the components.

[0035] To achieve dual dust removal, filtration of particulate matter, and protection of the operating environment and personnel health, please refer to [link / reference needed]. Figure 1 and Figure 2 In this embodiment, the first collection mechanism 3 includes a collection hopper 31 fixedly connected to the inside of the machine body 1, an installation box 32 fixedly connected to one side of the machine body 1, a first negative pressure fan 33 rotatably installed inside the installation box 32, and a filter plate 34 slidably connected inside the installation box 32. A guide pipe is fixedly connected between the collection hopper 31 and the installation box 32. The filter plate 34 is located on the air inlet side of the first negative pressure fan 33 and is used to filter dust particles. The first collection mechanism 3 and the second collection mechanism 4 work together to form a dual dust removal system. The collection hopper 31 can collect dust and slag scattered during the cutting process. The guide pipe ensures that the dust is smoothly transported to the installation box 32. The first negative pressure fan 33 provides stable suction. The filter plate 34 can effectively filter fine particles in the dust, avoiding environmental pollution and damage to the health of operators. At the same time, the filter plate 34 is slidably set, which is convenient for disassembly, cleaning and replacement, reducing equipment maintenance costs.

[0036] The working principle of the above embodiments is as follows: First, the workpiece to be cut is placed on the surface of the support plate 12 of the machine body 1. The support plate 12 is fixedly connected to the inner wall of the mounting base 11 to provide stable support for the workpiece and ensure the smoothness of the cutting process. After the equipment is started, the electric guide rail 13 fixedly installed on the surface of the mounting base 11, the slide block 14 slidably connected to its outside, the electric slide table 15 fixed on the surface of the slide block 14, the electric slider 16 slidably on the outside of the electric slide table 15, the fixed frame 17 fixed on the surface of the electric slider 16, and the electric telescopic cylinder 18 fixed on the top of the fixed frame 17 work together to drive the laser cutter 2 fixed to the output end of the electric telescopic cylinder 18 to achieve three-dimensional movement adjustment and accurately align with the preset cutting position of the workpiece. At the same time, the collection box 41 of the second collection mechanism 4 fixed to the back of the fixed frame 17 moves synchronously with the laser cutter 2 to ensure that the dust removal structure and the cutting point are always synchronized and to avoid the occurrence of dust suction blind spots. When the laser cutter 2 starts cutting, the abutment structure 5, which is fixedly connected to its exterior via the connecting frame 51, starts working simultaneously. The ball 57 fixed at the bottom of the movable sleeve 56 of the abutment structure 5 fits tightly against the surface of the workpiece. The movable sleeve 56 slides up and down along the mounting cylinder 53, and the pin 59 fixed on its inner wall slides in the spiral groove 55 opened inside the rotating column 54, thereby driving the rotating column 54 to rotate around the mounting cylinder 53. The abutment spring 58 fixed on the bottom wall of the movable sleeve 56 cooperates with the transmission groove opened inside the rotating column 54 to realize the automatic reset of the movable sleeve 56, ensuring that the ball 57 always fits tightly against the surface of the workpiece, adapting to workpieces with different flatness, and avoiding the protective cover 52 from loosening due to the undulation of the workpiece surface. At the same time, it assists the rotating column 54 to rotate smoothly, driving the inclined platform 510 fixed at the top of the rotating column 54 to rotate smoothly and synchronously, providing continuous and stable power support for the subsequent linkage of the follow-up piston structure 6 and the striking structure 7. During the rotation of the inclined platform 510, it abuts against the abutting cylinder 613 fixed inside the moving plate 611, pushing the moving plate 611 to slide up and down along the limiting rod 610 fixed at the top of the mounting cylinder 53. The tension spring 612 fixed between the moving plate 611 and the mounting cylinder 53 realizes the automatic reset of the moving plate 611, ensuring that the abutting cylinder 613 is always in close contact with the inclined platform 510, thus ensuring the stability of power transmission. When the moving plate 611 slides up and down, the roller 616 hinged on its outer side rolls in the inclined groove 615 opened inside the transmission block 614 fixed on the bottom side of the piston cylinder 63, thereby driving the piston cylinder 63 to move back and forth along the guide rod 61 fixed outside the protective cover 52 through the sliding sleeve 62, realizing the precise linkage between the abutting structure 5 and the follower piston structure 6, and ensuring that the two work together. When the follower piston structure 6 is working, the piston cylinder 63 reciprocates along the guide rod 61. The check valve 67 fixedly connected to its upper side cooperates with the air inlet pipe 69 to realize one-way air intake. The check valve 67 fixedly connected to its lower side cooperates with the exhaust pipe 68 to blow air towards the cutting path outside the protective cover 52, cleaning the floating dust and debris on the surface of the workpiece in advance, avoiding the scattering of laser energy caused by floating dust, thereby preventing the cutting edge burning phenomenon and improving the surface finish of the workpiece. At the same time, the piston rod 64 slidably connected inside the piston cylinder 63 reciprocates under the action of the return spring 66 fixed between it and the abutment plate 65, driving the abutment plate 65 to periodically strike the mounting cylinder 53, thereby transmitting the striking force to the protective cover 52, realizing active cleaning of the outside of the protective cover 52, preventing smoke and dust from adhering to the inner wall of the protective cover 52, avoiding blockage of the dust suction channel, and ensuring the dust removal effect. As the moving plate 611 slides up and down, its externally fixed linkage plate 71 synchronously drives the moving ring 72 to reciprocate. The rubber block 73 fixed on the bottom side of the moving ring 72 closely adheres to the surface of the annular suction tube 43. With the reciprocating motion of the moving ring 72, it periodically knocks on the annular suction tube 43, actively removing the smoke and dust attached to the inner wall of the annular suction tube 43, preventing the annular suction tube 43 from becoming blocked, and ensuring the smoke and dust extraction efficiency of the second collection mechanism 4. At this time, the second negative pressure fan 42, which is rotatably connected inside the collection box 41 of the second collection mechanism 4, starts and generates a stable suction force. The annular suction tube 43, which is fixedly connected to the inner wall of the protective cover 52, quickly captures the smoke and dust at the source of the cutting point. The smoke and dust are transported to the inside of the collection box 41 through the conveying pipe 44, which is fixedly connected between the collection box 41 and the second negative pressure fan 42. The collection plate, which is slidably connected inside the collection box 41, collects the smoke and dust. The collection plate can be quickly removed to clean the smoke and dust, reducing the difficulty of equipment maintenance. Dust and slag scattered during the cutting process fall into the collection hopper 31, which is fixedly connected inside the machine body 1. The collection hopper 31 is then transported to the installation box 32, which is fixedly connected to one side of the machine body 1, through the guide pipe between the collection hopper 31 and the installation box 32. The first negative pressure fan 33, which is rotated and installed inside the installation box 32, starts and generates a stable suction force, which draws the dust and smoke inside the installation box 32 into its interior. The dust and fine smoke particles are filtered by the filter plate 34, which is located on the air inlet side of the first negative pressure fan 33 and is slidably connected inside the installation box 32. This achieves the separation of dust, fine smoke particles and gas, avoiding environmental pollution and damage to the health of operators. At the same time, the filter plate 34 is set in a sliding manner, which is convenient for subsequent disassembly, cleaning and replacement, further reducing equipment maintenance costs. Throughout the entire operation, the main body 1 provides installation support for each structure, the laser cutter 2 is responsible for the core cutting operation, the contact structure 5, the follow-up piston structure 6, and the striking structure 7 work together in mechanical linkage, and the first collection mechanism 3 and the second collection mechanism 4 cooperate to form a dual dust removal system, ultimately achieving the integrated functions of laser precision cutting, dust removal, noise reduction, active cleaning, and edge burn prevention, ensuring stable, efficient, and low-maintenance operation of the equipment. The linkage of all structures is based on their fixed connection, sliding connection, or rotational connection relationship, ensuring the rationality and feasibility of the working principle.
