Description

Technical Field

[0001] The present application relates to the technical field of dust collection devices, and in particular to a dust collection device for an engraving machine and an engraving machine. Background Art

[0002] The engraving machine dust collection device is an important auxiliary equipment of the engraving machine. It is mainly used to collect dust, debris, etc. generated during the engraving process to improve the working environment, protect the health of operators, and extend the service life of the equipment.

[0003] The existing engraving machine vacuum devices all use relatively large suction hoses with crude structures and poor dust collection effects. They are particularly difficult to adapt to materials (or fabrics) of different thicknesses, as well as changes in tool feed during the engraving process. This causes chips and dust to fly during engraving or cutting, and static electricity to accumulate in the air, seriously affecting the cutting environment and the safety of the cutting equipment, and is also prone to fire. Summary of the Invention

[0004] The purpose of this application is to provide an engraving machine dust suction device and an engraving machine, which solves the problem that traditional dust suction devices have poor dust suction effect due to their difficulty in adapting to materials of different thicknesses and changes in tool feed rate during the engraving process.

[0005] To achieve the above-mentioned purpose, the present application provides a dust collection device for an engraving machine, comprising:

[0006] Dust suction pipe, used to be fixed on the tool module;

[0007] A dust collection block is in communication with the dust collection pipe and is adapted to be movably connected to the tool module so that the dust collection block can move relative to the tool module during the dust collection process;

[0008] The flexible dust suction cover is connected to the dust suction block and is used to cover the tool of the tool module in a plane perpendicular to the moving direction of the dust suction block. It is also used to deform when the tool processes the material and push the dust suction block to move.

[0009] In some embodiments, the engraving machine dust collection device also includes a guide mechanism, which includes a guide rod and a guide sleeve. The guide sleeve is fixed in the dust collection block, and the guide rod is used to be fixed on the tool module. The guide sleeve and the guide rod are slidably matched to make the dust collection block and the tool module movably connected.

[0010] In some embodiments, the guide mechanism also includes an elastic member, which is sleeved on the guide rod, and one end of the elastic member is used to be fixed on the tool module, and the other end is abutted against the dust collection block. The elastic member is used to provide elastic force to the dust collection block so that the dust collection block has a tendency to move away from the tool module.

[0011] In some embodiments, the engraving machine dust collection device further includes a driving mechanism, which is used to drive the dust collection block to move along the guide rod.

[0012] In some embodiments, the engraving machine dust collection device further comprises:

[0013] A position sensor is provided on the dust collecting block and is used to detect the relative position between the dust collecting block and the tool module or the material;

[0014] The control module is connected to the position sensor for receiving the detection signal of the position sensor and transmitting the detection signal to the engraving machine control system to control the driving mechanism to adjust the position of the dust collecting block.

[0015] In some embodiments, the flexible dust hood comprises:

[0016] Connecting flange, connected to the dust collection block;

[0017] The flexible brush is fixed to the connecting flange along the circumferential direction and is used to abut the material during tool processing.

[0018] In some embodiments, a magnetic quick-release ring is provided at the connection between the connecting flange and the dust suction block. The magnetic quick-release ring is fixed by magnetic attraction and can be rotated 360 degrees to adjust the angle.

[0019] In some embodiments, a guide plate is provided inside the dust collection block, and the guide plate divides the air flow channel in the dust collection block into multiple vortex chambers to enhance the centrifugal sedimentation of flying debris.

[0020] In some embodiments, the engraving machine dust collection device also includes a pressure sensor, which is installed on the dust collection pipe. The pressure sensor is used to detect the negative pressure value of the dust collection pipe during the dust collection process and transmit the detection signal to the engraving machine control system to adjust the suction force of the dust collection pipe.

[0021] The present application further provides an engraving machine, comprising a tool module, and an engraving machine dust collection device fixed to the tool module, such as any of the above items, the engraving machine further comprising:

[0022] Tool holder module;

[0023] A first clamping block is connected to the tool holder module and is used to fix the tool module to the tool holder module;

[0024] The second clamping block is connected to the first clamping block and is used to fix the engraving machine dust collection device to the first clamping block.

[0025] In contrast to the above background technology, the engraving machine dust collection device provided in the embodiments of the present application includes a dust collection pipe, a dust collection block, and a flexible dust collection hood. The dust collection pipe is fixed to the tool module; the dust collection block is connected to the dust collection pipe and is movably connected to the tool module, allowing the dust collection block to move relative to the tool module during the dust collection process; and the flexible dust collection hood is connected to the dust collection block. The flexible dust collection hood covers the tool of the tool module in a plane perpendicular to the direction of movement of the dust collection block. The flexible dust collection hood can also deform and push the dust collection block to move when the tool processes the material.

[0026] In this way, when the tool is processing the material, the flexible dust cover can be deformed and push the dust block to move upward. The engraving machine dust collection device set in this way has at least the following beneficial effects:

[0027] Since the flexible dust hood can tightly cover the tool of the tool module, it can ensure that the dust and debris generated when the tool processes the material are sucked into the dust collection device in time, which can reduce the diffusion of dust and debris in the air and improve the dust collection effect. At the same time, the flexible dust collection hood can elastically deform when the tool processes the material, so that it can adapt to the movement trajectory of the tool and maintain close contact with the material or fabric, further reducing dust leakage and improving the dust collection effect. In addition, the dust collection block can move relative to the tool module during the tool processing process, which means that the dust collection block can adjust its position as the tool moves, always maintaining the optimal dust collection position. This dynamic adjustment function ensures the continuity and efficiency of the dust collection effect. In this way, the engraving machine dust collection device using the above-mentioned setting method can adapt to materials of different thicknesses and changes in the tool feed rate during the engraving process, greatly improving the scope of application and versatility of the device, and solving the problem of poor dust collection effect caused by the difficulty of traditional dust collection devices in adapting to materials of different thicknesses and changes in the tool feed rate during the engraving process.

[0043] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0044] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0045] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the assembly of the engraving machine dust collection device and the tool module in the embodiment of the present application. Figure 2 This is a schematic diagram of the assembly of the engraving machine dust collection device, the tool module and the tool holder module in the embodiment of the present application.

[0046] The engraving machine dust collection device provided in the embodiment of the present application includes a dust collection pipe 10 , a dust collection block 20 and a flexible dust collection cover 30 .

[0047] The dust suction pipe 10 is fixed to the tool module 70. The tool module 70 can be fixed to the tool holder module 80 via a first clamping block 90. The tool holder module 80 drives the tool module 70 to move. The dust suction pipe 10 can be fixed to the tool module 70 via a second clamping block 100. For example, the dust suction pipe 10 is fixed to the second clamping block 100 via an upper flange seat 50. The second clamping block 100 is connected and fixed to the first clamping block 90. The first clamping block 90 can be fixed to the tool holder module 80 via a connecting plate 110.

[0048] The dust collection block 20 is connected to the dust collection pipe 10 through the lower flange seat 60, so that after the dust collection block 20 is connected to the dust collection pipe 10, a channel for transporting chips and dust is formed. The dust collection block 20 is movably connected to the tool module 70, so that the dust collection block 20 can move relative to the tool module 70 during the dust collection process.

[0049] For example, the dust suction pipe 10 may include a rigid pipe part and a flexible pipe part. The rigid pipe part is connected to the external dust collection box, and the flexible pipe part is connected between the dust suction block 20 and the rigid pipe part. The flexible pipe part can undergo elastic deformation or flexibly expand and contract during the movement of the dust suction block 20, so that the dust suction block 20 can move relative to the tool module 70 or the rigid pipe part during the dust suction process.

[0050] The flexible dust hood 30 is connected to the dust block 20. The flexible dust hood 30 covers the tool of the tool module 70 or the processing area where the tool is currently located in a plane perpendicular to the moving direction of the dust block 20. When the tool processes the material, the flexible dust hood 30 can also deform and push the dust block 20 to move.

[0051] The flexible dust collection cover 30 can be made of an elastic material. The flexible dust collection cover 30 can be elastically deformed when the tool processes the material to adapt to the movement trajectory of the tool and maintain close contact with the tool.

[0052] In this way, when the tool is processing the material, the flexible dust collection cover 30 can be deformed and push the dust collection block 20 to move upward.

[0053] With this arrangement, since the flexible dust hood 30 can tightly cover the tool of the tool module 70, it can ensure that the dust and debris generated when the tool processes the material are promptly sucked into the dust collection device, thereby reducing the diffusion of dust and debris in the air and improving the dust collection effect. At the same time, the flexible dust hood 30 can undergo elastic deformation when the tool processes the material, so that it can adapt to the movement trajectory of the tool and maintain close contact with the material or fabric, further reducing dust leakage and improving the dust collection effect. In addition, the dust collection block 20 can move relative to the tool module 70 during the tool processing process, which means that the dust collection block 20 can adjust its position as the tool moves, always maintaining the optimal dust collection position. This dynamic adjustment function ensures the continuity and efficiency of the dust collection effect.

[0054] In this way, the engraving machine dust collection device using the above-mentioned setting method can adapt to materials of different thicknesses and changes in tool feed rate during the engraving process, greatly improving the applicability and versatility of the device, and solving the problem of poor dust collection effect caused by the difficulty of traditional dust collection devices in adapting to materials of different thicknesses and changes in tool feed rate during the engraving process.

[0055] In some embodiments, the engraving machine dust collection device also includes a guide mechanism 40, which includes a guide rod 41 and a guide sleeve 42. The guide sleeve 42 is fixed in the dust collection block 20, and the guide rod 41 is used to be fixed on the tool module 70. The guide sleeve 42 slides with the guide rod 41 to make the dust collection block 20 movably connected to the tool module 70.

[0056] As can be seen, the sliding fit between the guide rod 41 and the guide sleeve 42 strictly restricts the movement of the suction block 20 to a single axial direction (generally perpendicular to the machining plane), preventing lateral deviation of the suction block 20 during movement and ensuring that the suction port is always aligned with the tool's cutting point, thereby improving dust capture efficiency. Furthermore, the guide rod 41 is directly fixed to the tool module 70, forming a rigid connection between the suction block 20 and the tool via the guide sleeve 42. When the tool is subjected to cutting reaction forces, the guide rod-guide sleeve system partially shares the load, reducing the vibration amplitude of the suction block 20 and preventing the flexible dust cover 30 from detaching from the material surface due to vibration. This is especially true when engraving curved lines or hard materials, where the tool may be subject to irregular reaction forces. The full contact between the inner wall of the guide sleeve 42 and the guide rod 41 (combined with high-hardness materials such as GCr15 bearing steel, with a hardness of HRC 60-62) protects against lateral impacts and prevents the suction block 20 from becoming stuck or deflecting.

[0057] In some embodiments, the guide mechanism 40 also includes an elastic member 43, which is sleeved on the guide rod 41, and one end of the elastic member 43 is used to be fixed on the tool module 70, and the other end is abutted against the dust collection block 20. The elastic member 43 is used to provide elastic force to the dust collection block 20 so that the dust collection block 20 has a tendency to move away from the tool module 70.

[0058] It's understandable that the pre-compression force of the elastic member 43 constantly forces the suction block 20 to move away from the tool module 70. When the tool processes materials of varying thickness, uneven surfaces can compress and retract the suction block 20. The elastic member 43 absorbs this displacement through compression. As the material surface degrades, the elastic member 43 releases its force, pushing the suction block 20 downward, maintaining a constant distance between the suction port and the work surface (typically controlled at 0.5-2 mm). This prevents the suction port from drifting away from the dust source due to fluctuations in the material, improving dust capture efficiency.

[0059] Furthermore, considering that tool vibration during high-speed operation of the engraving machine can easily cause the dust collection block 20 to vibrate, the provision of elastic member 43 allows its preloaded force to offset some of the vibration energy, reducing the vibration amplitude of the dust collection block 20. When the dust collection block 20 accidentally strikes a workpiece or fixture, the elastic member 43 absorbs the impact energy through compression deformation, preventing rigid collisions between the guide rod 41 and the guide sleeve 42, reducing the risk of component deformation, and extending the service life of the device. In particular, when the tool is subjected to lateral cutting forces, the elastic member 43 deforms to share some of the load, preventing the dust collection block 20 from tilting or becoming stuck due to uneven force.

[0060] In some embodiments, the engraving machine dust collection device further includes a driving mechanism, which is used to drive the dust collection block 20 to move along the guide rod 41.

[0061] In this way, a drive mechanism (such as a pneumatic cylinder or servo motor) drives the suction block 20 along the guide rod 41 based on the real-time position of the suction block 20 (feedback from the position sensor), maintaining a preset spacing (e.g., 0.5-2 mm) between the suction block 20 and the tool module. For example, when the tool is engraving on a curved workpiece, the suction block 20 can rise and fall along the tool's Z axis, preventing the suction port from being separated from the dust source due to height changes.

[0062] In some embodiments, the engraving machine dust collection device further includes a position sensor and a control module. The position sensor is provided on the dust collection block 20 and is used to detect the relative position between the dust collection block 20 and the tool module 70 or the material. The control module is communicatively connected to the position sensor and is used to receive detection signals from the position sensor and transmit them to the engraving machine control system to control the drive mechanism to adjust the position of the dust collection block 20.

[0063] A position sensor detects the distance between the suction block 20 and the material surface, and the control module adjusts the drive mechanism's stroke in real time. For example, if the material surface is uneven, the system automatically lifts the suction block 20 to avoid collision, or presses it down to fill gaps, ensuring a tight fit between the flexible suction hood 30 and the work surface.

[0064] Of course, according to actual needs, the position sensor can be a laser ranging sensor. The detection accuracy of the laser ranging sensor is ±0.01mm. Combined with the control module (such as the STM32 controller) to process the signal in real time, the drive mechanism response time is less than 50ms, which significantly reduces the frequency of manual adjustment.

[0065] In addition, the control module can also be interconnected with the engraving machine main control system through the communication module, synchronously obtain the tool coordinates and motion trajectory, predict the movement path of the dust collection block 20, and realize forward control.

[0066] In some embodiments, the flexible dust cover 30 includes a connecting flange 31 and a flexible brush 32 .

[0067] The connecting flange 31 is connected to the dust collecting block 20 ; the flexible brush 32 is fixed to the connecting flange 31 along the circumferential direction, and the flexible brush 32 is used to abut against the material during tool processing.

[0068] Traditional rigid hoods require a safe gap (typically greater than or equal to 3mm) between the hood and the material, allowing dust to escape through these gaps. In contrast, the flexible brush 32 is made of highly elastic nylon or synthetic fiber. Its bristles automatically deform with the undulations of the material surface, forming a physical seal. For example, when engraving curved or irregular workpieces, the brush can fit snugly into gaps as small as 0.1-5mm, reducing dust escape by over 40%. Furthermore, the brush structure blocks external airflow (such as workshop ventilation or turbulence generated by tool movement) from entering the suction area, preventing dust from being blown away.

[0069] Furthermore, when the hood accidentally contacts a workpiece or fixture, the flexible brushes 32 absorb kinetic energy through deformation, preventing the rigid flange from directly impacting the workpiece or causing scratches or deformation of the hood. This is particularly useful in the sudden displacement scenarios of high-speed engraving machines.

[0070] In order to facilitate assembly and disassembly, a magnetic quick-release ring is provided at the connection between the connecting flange 31 and the dust suction block 20. The magnetic quick-release ring is fixed by magnetic attraction and can be rotated 360 degrees to adjust the angle.

[0071] It's important to note that the magnetic quick-release ring utilizes a strong magnet (such as neodymium iron boron, with a magnetic attraction of 20-30 N / cm²) to instantly separate the flexible hood 30 from the suction block 20, eliminating the need for tightening bolts or removing clips. This allows for single-handed maintenance, reducing maintenance time from the traditional 3-5 minutes to under 5 seconds. Furthermore, since the flexible hood 30 is prone to accumulating swarf and dust, the quick-release design allows for direct removal for flushing or replacement, preventing dust clogging and reduced suction power.

[0072] Furthermore, the flexible dust hood 30 rotates freely around its magnetic axis. When engraving curved or irregular surfaces, the flexible dust hood 30 automatically adjusts its angle to the workpiece's surface, ensuring that the flexible brush 32 or sealing edge remains in close contact with the workpiece. This significantly reduces dust escape compared to a rigid connection.

[0073] In some embodiments, a guide plate is provided inside the dust collecting block 20 , and the guide plate divides the air flow channel in the dust collecting block 20 into a plurality of vortex chambers for enhancing the centrifugal sedimentation of flying debris.

[0074] Specifically, the guide plate divides the airflow path in the dust collector 20 into multiple independent vortex chambers (typically 3-6). Airflow enters each chamber and rotates along a spiral path (increasing tangential velocity by 30-50%). Dust particles are flung toward the chamber walls by centrifugal force. Large particles larger than 50μm are rapidly settled in the first vortex chamber, while fine particles 5-10μm in size are progressively separated in subsequent chambers, resulting in a 20-35% improvement in separation efficiency compared to a single-chamber design.

[0075] In some embodiments, the flexible dust cover 30 is trumpet-shaped or funnel-shaped, and the opening of the flexible dust cover 30 faces away from the dust collection block 20 .

[0076] The design of the opening of the flexible dust hood 30 facing away from the dust collection block 20 allows the flexible hood body (such as a brush material) to extend outward, which can completely cover the tool when the Z-axis of the engraving machine is raised or lowered or the robotic arm is operating. The opening of the flexible dust hood 30 is lower than the bottom end of the tool to prevent chips or dust from escaping. At the same time, the flexible dust hood 30 is set to a trumpet-shaped structure, which can expand the capture area of ​​chips or dust, so that the effective coverage range of the dust hood is increased.

[0077] In some embodiments, the engraving machine dust collection device also includes a pressure sensor, which is installed on the dust collection pipe 10. The pressure sensor is used to detect the negative pressure value of the dust collection pipe 10 during the dust collection process and transmit the detection signal to the engraving machine control system to realize the function of automatically adjusting the suction force of the dust collection pipe 10.

[0078] In some embodiments, the engraving machine dust collection device further includes a dust collection box, which is connected to the dust collection pipe 10 and is used to collect dust and debris sucked from the dust collection block 20.

[0079] In addition, a filter device may be provided in the dust box, which is used to filter the inhaled dust and debris to prevent the dust from entering other parts of the engraving machine.

[0080] The present application provides an engraving machine, including a tool module 70, and an engraving machine dust collection device fixed on the tool module 70 as described in the above specific embodiment. The engraving machine also includes a tool holder module 80, a first clamping block 90 and a second clamping block 100.

[0081] Among them, the first clamping block 90 is connected to the tool holder module 80, and the first clamping block 90 is used to fix the tool module 70 to the tool holder module 80; the second clamping block 100 is connected to the first clamping block 90, and the second clamping block 100 is used to fix the engraving machine dust collection device to the first clamping block 90.

[0082] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
