Description

Technical Field

[0001] This utility model belongs to the field of laser processing equipment technology, specifically relating to a dust removal device for a laser cutting machine. Background Technology

[0002] The development of dust collection devices is closely related to industrial environmental protection needs. In the early days, simple mechanical filtration or gravity sedimentation methods were mostly used, which were inefficient and difficult to handle fine particles. As industrial dust pollution became increasingly prominent, technologies such as bag filters, electrostatic precipitators, and wet scrubbers emerged, gradually improving filtration accuracy and automation. Modern dust collection devices further combine high-efficiency filter media, pulse backflushing cleaning systems, and intelligent monitoring technology, enabling them to dynamically adapt to different dust characteristics. They are widely used in industrial scenarios such as wood processing, metal smelting, chemical production, and building materials manufacturing, playing a key role in reducing occupational health hazards and meeting environmental emission standards.

[0003] Traditional side-suction devices are prone to creating turbulence during dust removal due to unreasonable airflow organization, which interferes with the laser beam path and seriously affects cutting accuracy. Fixed dust collection hoods cannot meet the processing requirements of workpieces of different thicknesses, causing fine metal dust to escape. Therefore, a dust removal device for laser cutting machines has emerged. Utility Model Content

[0025] Example

[0026] Reference Figures 1-4 This embodiment of the present invention provides a dust removal device for a laser cutting machine, comprising:

[0027] The system includes a support frame 101, a base frame 102 fixedly connected to the side wall of the support frame 101, a mounting frame 103 fixedly connected to the surface of the support frame 101, a drive motor 104 adapted to be installed on the side wall of the mounting frame 103, a power distribution box 105 fixedly connected to the side wall of the support frame 101, a transport assembly 106 fixedly connected to the side wall of the mounting frame 103, an auxiliary assembly 107 fixedly connected to the surface of the transport assembly 106, and a dust collection assembly 108 fixedly connected to the side wall of the base frame 102.

[0028] The transport assembly 106 includes a transport frame 106a fixedly connected to the side wall of the mounting frame 103, a drive shaft 106b adapted to be installed at the end of the transport frame 106a, a perforated transport belt 106c drivenly connected to the surface of the drive shaft 106b, an auxiliary roller 106d movably connected to the side wall of the transport frame 106a, an adjusting screw 106e threadedly connected to the inner wall of the auxiliary roller 106d, and an abutment roller 106f fixedly connected to the bottom of the transport frame 106a.

[0029] Specifically, the inner wall of the perforated conveyor belt 106c is connected to the surface of the abutment roller 106f, and the adjusting screw 106e is threadedly connected to the inner wall of the conveyor frame 106a.

[0030] The auxiliary component 107 includes a connecting frame 107a that is snapped to the side wall of the transport frame 106a, and a baffle 107b that is movably connected to the side wall of the connecting frame 107a. The auxiliary component 107 also includes a fixing bolt 107c that is threaded to the inner wall of the connecting frame 107a, and a curtain box 107d that is fixedly connected to the side wall of the baffle 107b. The auxiliary component 107 also includes an adsorption box 107e that is fixedly connected to the bottom of the transport frame 106a, a connecting pipe 107f that communicates with the side wall of the adsorption box 107e, and a cover 107g that is fixedly connected to the surface of the connecting frame 107a.

[0031] Furthermore, the surface of the curtain box 107d is movably connected with a rubber curtain, which facilitates the entry and exit of workpieces, while blocking metal dust and exhaust gas generated during cutting, thus facilitating dust removal operations.

[0032] Preferably, the vacuuming assembly 108 includes a vacuum pipe 108a connected to the surface of the connecting pipe 107f, and a vacuum pump 108b connected to the end of the vacuum pipe 108a. The vacuuming assembly 108 also includes an exhaust pipe 108c connected to the side wall of the vacuum pump 108b, and a collection box 108d connected to the end of the exhaust pipe 108c.

[0033] It should be noted that the vacuum pump 108b is fixedly connected to the surface of the base frame 102, and the vacuum pipe 108a is used in conjunction with the connecting pipe 107f to generate suction in the suction box 107e. Through the opening of the suction box 107e, the smoke and dust are adsorbed through the perforated conveyor belt 106c.

[0034] In use, the laser cutting machine is mounted on the connecting frame 107a, the workpiece is placed on the surface of the conveyor belt, and the drive motor 104 is started. The drive motor 104 drives the drive shaft 106b via a belt, and the drive shaft 106b drives the perforated conveyor belt 106c to move. The height of the auxiliary roller 106d can be adjusted by adjusting the bolts, thereby adjusting the area of ​​connection between the perforated conveyor belt 106c and the drive shaft 106b, and thus adjusting the moving speed of the perforated conveyor belt 106c. The abutment roller 10... The 6f abuts against the inner wall of the perforated conveyor belt 106c, causing the conveyor belt below to move towards the transport frame 106a, thus leaving a gap for the placement of the adsorption box 107e. When the workpiece is being cut, the dust pump 108b transports the dust, and together with the dust suction pipe 108a and the connecting pipe 107f, a negative pressure is generated in the adsorption box 107e. The adsorption box 107e adsorbs the dust through the holes on the surface of the perforated conveyor belt 106c. The absorbed dust enters the collection box 108d through the discharge pipe 108c.

[0035] In summary, the efficient dynamic collection of fumes during laser cutting is achieved through the coordinated use of the support frame 101, mounting frame 103, and transport assembly 106. The perforated conveyor belt 106c, driven by the drive shaft 106b and the abutment roller 106f, forms a continuous conveying plane, and the adjustable auxiliary roller 106d enables precise control of the conveying speed. The adsorption box 107e, through a negative pressure system formed by the connecting pipe 107f and the dust pump 108b, creates a directional airflow below the perforated conveyor belt 106c, thus preventing the cutting fumes from entering the air. Dust is forcibly sucked in through the holes in the conveyor belt, and the sealing structure formed by the baffle box 107d and the rubber baffle effectively prevents the spread of smoke and dust. Finally, the smoke and dust are concentrated in the collection box 108d through the discharge pipe 108c. This structure ensures continuous conveying of workpieces while realizing the spatial coupling between the cutting station and the dust removal area. It avoids the airflow interference problem of traditional side-suction dust removal and greatly improves the dust collection efficiency through the modular design of the dust collection component 108. It is especially suitable for industrial scenarios of high-frequency and high-precision laser cutting operations.
