Description

Technical Field

[0001] This utility model relates to the technical field of dust removal devices for laser cutting machines, specifically, to a dust removal device for laser cutting machines. Background Technology

[0002] In the field of laser cutting, the metal dust, fumes, and other pollutants generated during the cutting process not only affect cutting precision and processing quality but also pose health risks to operators. Furthermore, dust accumulation can lead to equipment malfunctions and shorten equipment lifespan. Most existing dust removal devices for laser cutting machines use fixed-position dust collection, which has limitations in dust removal range and cannot effectively follow the cutting position in real time. Traditional dust removal devices also lack pre-settling treatment for dust, leading to widespread dust splashing. Therefore, a new type of dust removal device for laser cutting machines is urgently needed. Utility Model Content

[0003] This utility model provides a dust removal device for a laser cutting machine. A dust settling tank is formed by a partition that is narrow at the top and wide at the bottom. The dust is initially settled by using the principle of gradually expanding channels. The partition array forms an independent airflow channel, which guides the dust to flow towards the suction nozzle, and works in conjunction with the negative pressure adsorption of the suction nozzle.

[0004] A dust removal device for a laser cutting machine includes a laser cutting machine worktable. Several evenly arranged partitions are fixedly arranged on the upper side of the worktable. The upper cross-section of each partition is smaller than the lower cross-section. Adjacent partitions form a dust settling trough that is wider at the top and narrower at the bottom. A baffle is fixedly connected to the middle of all the partitions, and the baffle fixes the laser cutting machine worktable. The laser cutting machine tool worktable has fixed ends of linear slide rails on both sides, and the movable ends of each linear slide rail are fixedly connected to both ends of the crossbeam frame. The movable ends of the linear slide rails are connected to the dust removal components.

[0005] Furthermore, the dust removal assembly includes an air intake nozzle. Each linear slide rail has an air intake nozzle fixedly installed on one side opposite to the movable end. The air intake nozzle is fixedly connected to a moving tube. Each moving tube has one end fixedly connected to a corrugated tube at both ends. The other end of each corrugated tube is fixedly connected to both ends of the laser cutting machine tool worktable. The corrugated tube is disposed in the slide rail formed by the fixed end of the linear slide rail and the partition. The slide rail formed by the fixed end of the linear slide rail and the partition matches the corrugated tube. The other ends of the two corrugated tubes at one end are fixedly connected to the air intake of the vacuum cleaner through a connecting tube.

[0006] Furthermore, the partition is a triangular piece.

[0007] Furthermore, a linear motor should also be installed on the crossbeam frame, the movement trajectory of the linear motor being perpendicular to the movement trajectory of the linear slide rail, and a laser cutting device being installed at the moving end of the linear motor.

[0008] Furthermore, the linear guide rail is an electric linear guide rail.

[0009] Compared with the prior art, the advantages and beneficial effects of this utility model are: A dust settling trough is formed by partitions that are narrow at the top and wide at the bottom. The principle of gradually expanding channels is used to achieve initial dust settling. The partition array forms an independent airflow channel to guide the dust to flow towards the air intake, which is combined with the negative pressure adsorption of the air intake. The linear guide rail drives the dust removal component to move horizontally along both sides of the workbench, and the linear motor on the crossbeam drives the laser cutting device to move vertically. The two work together to enable the dust removal component to follow the laser cutting position in real time, achieving dynamic dust removal in the entire area of ​​the workbench and avoiding dust residue. The triangular baffle has good structural stability and can withstand airflow impact and dust pressure; the corrugated pipe is set in a specific slide, which can not only move and bend flexibly with the dust removal components, but also prevent the pipe from getting tangled or damaged, ensuring the long-term stable operation of the dust removal system.

[0012] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings. In the description of this invention, it should be noted that the terms "left," "right," "front," "rear," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0013] The following is in conjunction with the appendix Figures 1-2 The present invention will be further described in terms of the embodiments and implementation methods.

[0014] A dust removal device for a laser cutting machine includes a laser cutting machine worktable 8. Several evenly arranged partitions 10 are fixedly arranged on the upper side of the worktable. The upper cross-section of each partition 10 is smaller than the lower cross-section. Adjacent partitions 10 form a dust settling trough that is wider at the top and narrower at the bottom. A baffle 11 is fixedly connected to the middle of all partitions 10, and the baffle 11 fixes the laser cutting machine worktable. The laser cutting machine tool worktable 8 has fixed ends of linear slide rails on both sides, and the movable ends of each linear slide rail are fixedly connected to both ends of the crossbeam frame 2. The movable ends of the linear slide rails are connected to the dust removal components.

[0015] In this embodiment, the upper cross-section of the partition 10 is smaller than that of the lower end (forming a structure that is narrower at the top and wider at the bottom). The adjacent partitions 10 form a dust settling trough. Utilizing the principle of "gradually expanding channel" in fluid mechanics, the cross-sectional area of ​​the channel is expanded, and the dust settles due to inertia, achieving preliminary dust removal. At the same time, when the dust removal component removes dust, the partitions 10 are evenly arranged to form multiple independent airflow channels, guiding the dust generated by cutting to flow in a specific direction. The baffle 11 ensures the stability of the partition 10 array and separates the workbench surface to prevent the disorderly diffusion of dust. The movable end of the linear slide rail drives the crossbeam frame 2 to move horizontally along both sides of the workbench, so that the dust removal component can cover the entire area of ​​the workbench, achieving dynamic dust removal.

[0016] The dust removal assembly includes an air intake 1. Each linear slide rail has an air intake 1 fixedly installed on one side of its movable end. The air intake 1 is fixedly connected to a moving tube. Each moving tube has one end fixedly connected to a corrugated tube 3 at both ends. The other end of each corrugated tube 3 is fixedly connected to both ends of the laser cutting machine tool worktable. The corrugated tube 3 is disposed in the slide rail 12 formed by the fixed end of the linear slide rail and the partition 10. The slide rail 12 formed by the fixed end of the linear slide rail and the partition 10 matches the corrugated tube 3. The other ends of the two corrugated tubes 3 at one end are fixedly connected to the air intake of the vacuum cleaner 5 through a connecting pipe 4.

[0017] The suction nozzle 1 is fixed to the movable end of the linear slide rail and moves with the cutting area as the slide rail moves. It directly adsorbs dust using the negative pressure generated by the vacuum cleaner 5. The moving tube connects the suction nozzle 1 and the corrugated tube 3 to form a rigid air guide channel, ensuring stable airflow. The corrugated tube 3 is flexible and is set in the slide 12 formed by the fixed end of the linear slide rail and the partition 10. The shape of the slide 12 matches the corrugated tube 3, allowing the corrugated tube 3 to fold as the dust removal component moves, while limiting its offset range to avoid pipe entanglement or damage. The two ends of the corrugated tube 3 are respectively connected to the moving tube and the fixed end of the workbench, forming a fixed-moving flexible connection to adapt to the reciprocating motion of the dust removal component. The two ends of the corrugated tube 3 converge to the suction port of the vacuum cleaner 5 through the connecting tube 4, forming a closed negative pressure circuit. Utilizing the principle of fluid continuity, a continuous airflow is generated at the suction nozzle 1 to achieve efficient dust collection.

[0018] The partition 10 is preferably a triangular piece. Triangles are stable, and their angular design can guide airflow to form turbulence, enhance the mixing of dust and airflow, and promote the movement of dust towards the suction nozzle 1. The cross-section of the triangle is narrower at the top and wider at the bottom (similar to an isosceles triangle). Combined with the principle of gradually expanding channels, the airflow path can be further optimized. The upper side of the apex of the triangle reduces airflow resistance, and the lower side of the base expands the dust settling space, thereby improving dust removal efficiency.

[0019] A linear motor should also be installed on the crossbeam frame 2. The movement trajectory of the linear motor is perpendicular to the movement trajectory of the linear guide rail. A laser cutting device (using existing products, not shown in the attached diagram) is installed at the moving end of the linear motor. The electric linear guide rail 7 integrates the motor, guide rail, and transmission mechanism. It controls the translation speed and position of the moving end through electrical signals. The electric linear guide rail 7 can be connected to the machine tool control system and linked with the linear motor and laser cutting device. It synchronously adjusts the movement trajectory of the dust removal component according to the preset program to ensure that the dust removal component matches the cutting position in real time.

[0020] The dust collector and laser cutting device are both existing products using existing technologies, and will not be described in detail here.

[0021] The method of using this utility model is as follows: The workpiece to be cut is placed on the worktable 8 of the laser cutting machine. According to the workpiece cutting requirements, the cutting path and parameters are input into the machine tool control system. The equipment is started, and the linear motor drives the laser cutting device to cut along the set trajectory. Simultaneously, the linear guide rail drives the dust removal component to move synchronously, ensuring that the suction nozzle 1 always follows the laser cutting position. Dust generated during the cutting process first settles in the dust settling tank formed by the partition 10. The remaining dust, under the negative pressure of the suction nozzle 1, is transported to the vacuum cleaner 5 through the moving pipe and corrugated pipe 3. After cutting, the dust collection tank of the vacuum cleaner 5 is opened, and the dust is removed for cleaning. 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's 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.
