Description

Technical Field

[0001] This utility model relates to the field of engraving machine equipment technology, specifically to a dust removal device for a three-axis engraving machine. Background Technology

[0002] A three-axis engraving machine is a CNC machining equipment that operates based on the XYZ three-dimensional coordinate system. It mainly consists of core components such as a frame, spindle, drive system, and control system. Relying on computer-aided design and manufacturing technology, it precisely controls the movement of the cutting tool in three vertical dimensions through program instructions to achieve engraving, cutting, milling and other processing operations on various materials such as wood, metal, and plastic.

[0003] Most existing three-axis engraving machines use a dust collection hood combined with a dust collection pipe for dust removal. However, in order to improve the dust collection effect, the dust collection hood needs to be as close as possible to the workpiece to form a closed space. This will limit the engraving operation. For irregularly shaped workpieces, curved surfaces, or materials with large height differences, the dust collection hood is difficult to completely fit the surface, which can easily form gaps and cause dust leakage. At the same time, the closed structure will also interfere with operations such as tool changing and workpiece clamping, reducing the flexibility of operation. Utility Model Content

[0021] 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.

[0022] Please see Figures 1-5 As shown, a dust removal device for a three-axis engraving machine includes a mounting base 1, which serves as a basic support structure, providing stable installation space and support for each component. A worktable 2 is mounted on the inner wall of the mounting base 1, acting as a workpiece support platform. Two sliding rods are located at the bottom of the worktable 2, and gear transmission is used to guide the sliding rods, allowing the engraving device to move back and forth. A drive unit 3 is slidably connected to the bottom drive end of the worktable 2, and an engraving machine 4 is mounted on the drive end of the drive unit 3. Linear guide rails are mounted on the drive unit 3 along the left-right direction, and the engraving machine 4 is fixedly connected to the slider on the guide rails. A synchronous belt is also included. Arranged along the guide rail, one end is connected to the drive motor 601, and the other end is fixed by a tension wheel, further enabling the engraving machine 4 to move laterally. The drive unit 3 and the base on which the engraving machine 4 is mounted are equipped with electric push rods, which can control the vertical movement of the engraving machine 4. Through the coordinated action of the above mechanical structures, the three components respectively realize the independent movement of the engraving machine 4 in the three dimensions of front-back, left-right, and vertical, thus forming a complete three-axis drive system to meet the motion requirements for three-dimensional engraving of the workpiece on the worktable 2. It should be noted that the above are all existing structures and will not be elaborated upon here. Other components include:

[0023] The dust removal component 5, installed inside the mounting base 1, can efficiently capture and collect the dust generated during the engraving process on the workbench 2, and achieve centralized collection and treatment of the dust, thereby keeping the processing area clean and reducing the impact of dust on equipment operation and the working environment.

[0024] The anti-clogging component 6, installed inside the dust collection chamber 503, can continuously clean the dust adhering to the surface of the filter plate 504, preventing dust accumulation from clogging the filter plate 504, ensuring smooth airflow in the dust collection chamber 503, ensuring stable negative pressure suction of the dust removal component 5, thereby maintaining the long-term effectiveness of dust removal and reducing the frequency of equipment downtime maintenance due to filter plate 504 clogging.

[0025] The dust removal assembly 5 includes dust collection plates 501 installed on the left and right sides of the outer wall of the mounting base 1. The workbench 2 is positioned between the two dust collection plates 501. The dust collection plates 501 serve as inlet structures for dust intake, and their outer walls have dense honeycomb-shaped through holes to guide dust generated in the processing area of ​​the workbench 2 into the dust collection chamber 503. Multiple fans 502 are installed on both the left and right sides of the outer wall of the mounting base 1. The fans 502 create a negative pressure environment within the dust collection chamber 503 through their operation, providing power for dust to enter the dust collection chamber 503 from the dust collection plates 501 and achieve subsequent filtration and collection. This is controlled by a PLC controller. Dust collection chambers 503 are also provided on both the left and right sides inside the mounting base 1. The dust collection chambers 503 serve as channels for dust transportation and temporary storage, receiving dust from the dust collection plates... Dust entering through chamber 501 is guided to filter plate 504 for filtration, while providing installation and operating space for anti-clogging component 6. Filter plates 504 are installed on the inner walls of the two dust collection chambers 503. As the core component of dust filtration, filter plates 504 can intercept and separate dust entering the dust collection chambers 503, preventing dust from being discharged with the airflow or entering the fan 502, causing equipment damage and environmental pollution. The outer walls of the two filter plates 504 are located at the front end of multiple fans 502. The bottom of both dust collection chambers 503 is connected to a dust collection chamber 505. The dust collection chamber 505 serves as a transition space for dust transfer, receiving dust that falls off after being filtered by filter plates 504 and guiding it to the dust collection box 507 for centralized collection. The bottom of the mounting base 1 has an installation cavity 5. 06. The mounting cavity 506 provides installation and storage space for the dust collection box 507. Both dust collection chambers 505 are connected to the interior of the mounting cavity 506. The dust collection box 507 is slidably connected to the inner wall of the mounting cavity 506. Through the communication structure between the mounting cavity 506 and the two dust collection chambers 505, the dust collection box 507 can collect the dust falling from the dust collection chambers 505, preventing dust from scattering and causing secondary pollution. At the same time, it is convenient for operators to regularly clean the collected dust, ensuring the continuous and stable operation of the dust removal system. The outlets of both dust collection chambers 505 are located at the top of the dust collection box 507. The outer wall of the dust collection box 507 is equipped with a handle 508. When dust removal work is required, the PLC controller controls the operation of multiple fans 502 on the left and right sides of the outer wall of the mounting base 1. A negative pressure environment is created in the dust collection chambers 503 on both sides inside the mounting base 1. Dust generated in the processing area of ​​the workbench 2 enters the dust collection chambers 503 through the dust collection plate 501 under the action of negative pressure. The dust is guided to the filter plate 504 installed on the inner wall of the dust collection chamber 503. After being intercepted and separated by the filter plate 504, the dust is prevented from being discharged with the airflow or entering the fan 502. The filtered dust falls into the dust collection chamber 505, which is connected to the bottom of the dust collection chamber 503. Then, through the connection structure between the dust collection chamber 505 and the mounting cavity 506 at the bottom of the mounting base 1, the dust is finally collected in the dust collection box 507, which is slidably connected to the inner wall of the mounting cavity 506. After the work is completed, the operator can easily remove and put away the box for regular cleaning through the handle 508 on the outer wall of the dust collection box 507.Ensure the stable and continuous operation of the dust removal system.

[0026] The anti-clogging component 6 includes motors 601 installed on the left and right sides of the outer wall of the mounting base 1. The drive ends of the two motors 601 are fixedly connected to lead screws 602. The threaded ends of the two lead screws 602 are rotatably connected to moving blocks 603. The outer walls of the two moving blocks 603 are fixedly connected to mounting frames 604. The interior of the two mounting frames 604 is provided with sliding cavities 605. The inner walls of the two sliding cavities 605 are fixedly connected to multiple springs 606. The other ends of the multiple springs 606 are fixedly connected to brushes 607. The outer walls of the two brushes 607 are slidably connected to the inner walls of the mounting frames 604. The bristle ends of the two brushes 607 are in contact with the outer wall of the filter plate 504. When the motors 601 are started by the PLC controller, their drive ends drive the lead screws 602 to rotate. The moving blocks 603, which are threadedly connected to the lead screws 602, move linearly along the axial direction under the transmission action of the lead screws 602. The moving block 603 synchronously drives the mounting frame 604, which is fixedly connected to the outer wall, to move. Multiple springs 606 fixed in the sliding cavity 605 inside the mounting frame 604 always apply elastic force to the brush 607, so that the bristles of the brush 607 are tightly attached to the outer wall of the filter plate 504. As the mounting frame 604 moves, the brush 607 slides on the surface of the filter plate 504, thereby cleaning the dust and other impurities attached to the surface of the filter plate 504, preventing the filter plate 504 from becoming blocked, and the swept dust will enter the dust collection box 507 through the dust collection cavity 505.

[0027] Working Principle: During operation, the drive unit 3, through gear transmission and the sliding rod at the bottom of the worktable 2, drives the engraving machine 4 to move back and forth. It also uses linear guides and synchronous belts along its left and right directions to drive the engraving machine 4 laterally. Simultaneously, the electric push rod on the mounting base controls the vertical movement of the engraving machine 4. This three-axis drive system, working in tandem, allows the engraving machine 4 to perform engraving processing on the workpiece in three-dimensional space according to a preset program. During this process, the operator starts the fan 502 via the PLC controller, creating a negative pressure environment in the dust collection chamber 503. Dust generated in the processing area of ​​the worktable 2, under this negative pressure, enters the dust collection chamber 503 through the honeycomb-shaped holes of the dust collection plates 501 on both sides, and is then guided to the filter plate 504 for further processing. The filter plate is intercepted and filtered to prevent dust from contaminating the equipment or environment. The dust that falls off after filtration is collected in the dust collection chamber 505 and then collected in the dust collection box 507. At the same time, the PLC controller starts the motor 601 of the anti-clogging component 6. The motor 601 drives the lead screw 602 to rotate, which drives the moving block 603 and the mounting frame 604 to move axially. The spring 606 in the mounting frame 604 applies an elastic force to make the brush 607 fit tightly against the filter plate 504. As the mounting frame 604 moves, it sweeps the dust on the surface of the filter plate 504. The swept dust also enters the dust collection box 507 through the dust collection chamber 505. After processing, the operator takes out the box through the handle 508 on the outer wall of the dust collection box 507 and cleans the collected dust to ensure the stable operation of the device in the future.
