Description

Technical Field

[0001] This utility model relates to the technical field of laser cutting fume treatment equipment, and in particular to a fume treatment system for an intelligent laser cutting machine. Background Technology

[0002] Laser cutting is a technology that uses lasers to cut materials, commonly used in industrial manufacturing applications. The working principle of laser cutting generally involves guiding a high-power laser output through optical devices. A laser optics system and a numerical control (CNC) system are used to guide the material or the generated laser beam. A commercial laser for cutting materials includes a motion control system to track the CNC commands or G-code corresponding to the trajectory to be cut. After the laser beam is focused and aligned with the material, the material melts, burns, evaporates, or is blown away by a gas jet, leaving an edge with a high-quality surface finish. Industrial laser cutting machines are generally used to cut flat materials as well as structural and piping materials. In the field of smart manufacturing, laser cutting of metal sheets is frequently required. For example, during cutting, a camera positions the cutting area, a control mechanism moves the laser emitter above the cutting area and aligns it with the laser cutting area, and then emits the laser to perform the cutting operation. Currently, conventional intelligent cutting machines include a mounting platform for limiting and placing the workpiece to be cut, a suspended frame supported on the mounting platform, a multi-directional displacement mechanism installed on the suspended mounting plane defined by the suspended frame, and a laser cutting head and a CNC control system located at the lower end of the multi-directional displacement mechanism. The CNC control system controls the laser power output, cutting path, and process parameters based on the image data collected by the CCD camera to achieve automated cutting by the laser cutting head. The multi-directional displacement mechanism includes a bidirectional translation structure that can position the laser cutting head at any point in the plane and a cylinder or hydraulic lifting rod for direct lifting, thereby effectively positioning the laser cutting head at any working point in a certain space.

[0003] During laser cutting, the processed material is locally charred or melted, generating mixed fumes containing a large amount of workpiece substrate debris. These diffused fumes affect the cleanliness of the cutting space, contaminate the laser path, and reduce cutting efficiency. Furthermore, the fumes affect the working environment; inhalation can harm health, and air pollution occurs. Therefore, a fume extraction mechanism is needed for the directional extraction and transfer of fumes. However, existing intelligent cutting machines typically have fume extraction and treatment systems fixed to the side edge of the mounting platform, unable to move with the laser cutting head. This results in some cutting areas not being effectively and quickly transferred by the fume extraction mechanism, leading to poor overall fume extraction performance. Moreover, existing fume extraction mechanisms often only use a single activated carbon filter to adsorb and remove VOCs, ozone, and odors, failing to effectively separate and recover material residues and debris, or treat acidic gases. This results in insufficient purification of the emitted fumes, impacting the surrounding air quality. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent laser cutting machine fume treatment system that effectively extracts and transfers fumes generated at real-time cutting points while moving synchronously with the laser cutting head. This system also utilizes a multi-stage filtration structure to differentiate and filter the fumes, ensuring high filtration efficiency. This addresses the problems of existing intelligent cutting machine fume extraction and treatment systems, which cannot effectively extract fumes generated at different cutting points, easily leaving residual fumes that contaminate the laser cutting optical path and lenses, affecting subsequent cutting quality. Leaking residual fumes can also easily harm the health of operators. Furthermore, existing fume treatment systems typically only use a single activated carbon adsorption filtration structure, resulting in insufficient filtration of harmful components and pollution of the surrounding air quality.

A slag discharge mechanism is disposed at the bottom of the inlet side of the intercepting filter plate, penetrating the bottom wall of the main filter chamber.

[0007] According to a preferred embodiment, an air inlet pipe head that can communicate its internal space with the air outlet of the air pump is inserted into the side of the main filter chamber, and an air outlet pipe head that communicates with its internal space and an end cap that seals the side opening of the main filter chamber are respectively provided on the bottom and side surfaces of the main filter chamber away from the air inlet pipe head; the bottom surface of the main filter chamber is also provided with a counterweight receiving secondary chamber that can accommodate part of the slag discharge mechanism.

[0009] According to a preferred embodiment, the cooling module includes annular heat exchange fins embedded in the inner annular wall of the sleeve and a heat transfer coil coiled around the heat dissipation annular surface of the annular heat exchange fins and passing through the cylinder body of the sleeve.

Several suction nozzles are inserted into the annular bottom surface of the cavity ring in a circumferential dot matrix pattern. A duct is also provided on the side of the cavity ring to directionally exhaust the flue gas that flows into its internal chamber.

[0013] The beneficial effects of this utility model are: The lifting and suction assembly provided in this application can be connected to the laser cutting head via a sleeve and mounting ring, allowing the assembly to move synchronously with the head. This ensures the assembly remains above the real-time cutting point, effectively and thoroughly drawing in and transferring cutting fumes, reducing residual fumes, minimizing their diffusion within the processing space, and preventing health hazards from accidental inhalation.

It should be noted that the descriptions of these embodiments are for the purpose of helping to understand this utility model, but do not constitute a limitation thereof. In some examples, because some implementation methods belong to existing or conventional technology, they are not described or are not described in detail. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and do not have any sequential or technical meaning.

[0017] The following is a detailed explanation with reference to the accompanying drawings. Example

[0018] This application provides a flue gas treatment system for an intelligent laser cutting machine, which includes a mounting ring 1, a sleeve 2, a cooling module 3, a lifting and suction assembly 4, a suction traction pipe 5, a first filter assembly 6, and a second filter assembly 7.

[0019] according to Figure 1-4 In one specific embodiment, the mounting ring 1 is detachably fitted onto a lifting column that mounts the laser cutting head and can adjust the working height of the laser cutting head. A sleeve 2, fitted around the outside of the laser cutting head, is provided on the bottom surface of the mounting ring 1. A cooling module 3, connected to an external circulating cooling device and capable of actively adjusting the ambient temperature outside the laser cutting head, is also embedded in the sleeve 2. A lifting suction assembly 4, capable of following the translation of the laser cutting head and sucking up the flue gas generated at the real-time cutting point, is also provided at the axial lower end of the sleeve 2. The lifting suction assembly 4 is also connected to a first filter assembly 6, capable of performing multi-stage preliminary filtration of the flue gas, via a suction traction pipe 5. The output end of the first filter assembly 6 is also connected to a second filter assembly 7, capable of washing the pre-filtered flue gas with water. The lifting and suction assembly 4 provided in this application can be connected to the laser cutting head through the sleeve 2 and the mounting ring 1, allowing the lifting and suction assembly 4 to move synchronously with the laser cutting head. This ensures that the lifting and suction assembly 4 is always above the real-time cutting point, effectively and fully sucking and transferring the cutting fumes, reducing fumes residue, minimizing the diffusion of fumes in the processing space, avoiding health hazards caused by accidental inhalation of fumes, and preventing the fumes from self-diffusion and contaminating the laser cutting head in the cutting space, thus improving the cleanliness and safety of the cutting process. The lifting and suction assembly 4 can be raised and lowered as needed to adjust the distance between itself and the workpiece, thereby ensuring a negative pressure suction and exhaust effect. The first filter assembly 6 and the second filter assembly 7 provided in this application construct a multi-stage filtration structure, thereby using different filtration methods to remove different components, improving the cleanliness and safety of the final exhaust gas, and reducing environmental pollution.

[0020] Preferably, the mounting ring 1 includes a radially extended ring plate and a locking sleeve, with the bottom of the locking sleeve integrally connected to the radially extended ring plate. Specifically, multiple locking screws are spaced apart on the locking sleeve, allowing the locking sleeve to be fixedly installed on the lifting column by adjusting the tightening of the locking screws as needed. Preferably, the bottom of the radially extended ring plate coaxially abuts against the sleeve 2, enabling the bolt structure penetrating the plate and inserted into the sleeve to effectively connect the two. Preferably, the inner wall of the sleeve 2 is equipped with a temperature sensor that is wirelessly connected to the temperature display screen, allowing the operator to adjust the current in the circuit connected to the ring heat exchange plate 31 and adjust the on / off state of the electrical circuit based on the temperature display data. Preferably, the cooling module 3 includes annular heat exchange plates 31 embedded in the inner annular wall of the sleeve 2 and a heat transfer coil 32 coiled around the heat dissipation annular surface of the annular heat exchange plates 31 and passing through the cylinder of the sleeve 2. Preferably, the heat transfer coil 32 has an inlet port 321 and an outlet port 322 at both ends, which pass through the cylinder of the sleeve 2 and can be connected to the outlet and inlet ports of an external circulating cooling device, respectively. The heat transfer coil 32 can be a heat exchange tube such as a copper tube with high thermal conductivity, and it forms a closed loop with the external circulating cooling device to use the circulating coolant continuously cooled by the external circulating cooling device to remove the heat absorbed by the heat transfer coil 32. Preferably, the annular heat exchanger 31 is a semiconductor heat exchanger capable of active heat transfer as needed, so that a low-temperature space with a temperature value lower than room temperature is formed within a certain space range in contact with its heat-absorbing end, thereby reducing the ambient temperature of the laser cutting head and allowing the laser cutting head to work in a low-temperature space, avoiding heat accumulation on its periphery and affecting the stability of its continuous operation.

[0021] Preferably, multiple lifting adjustment rods 41 of the lifting suction assembly 4 are arranged at circumferential intervals on the bottom annular surface of the sleeve 2. More preferably, a hollow annular body 42 capable of guiding flow is also connected to the axial lower end of the lifting adjustment rods 41. Specifically, a plurality of suction nozzles 43 connecting the internal chambers of the hollow annular body 42 to the outside are inserted on the annular bottom surface of the hollow annular body 42 in a circumferential dot matrix pattern, so that external smoke is directionally input into the internal chambers of the hollow annular body 42 through the suction nozzles 43 under the directional negative pressure traction force. Preferably, a duct 44 is also provided on the side of the hollow annular body 42 to directionally discharge the smoke that has entered its internal chambers. Preferably, the lifting and adjusting rod 41 is a ZKLE630S type high-precision hydraulic telescopic rod that can automatically extend and retract under the operator's control, thereby changing the working height of the cavity ring 42. This allows the cavity ring 42 to be synchronously positioned directly above the real-time cutting point as it moves with the laser cutting head. This ensures that the cavity ring 42 effectively extracts smoke from a safe distance from the real-time cutting point, guaranteeing the effectiveness and completeness of smoke extraction. The lifting and suction assembly 4 provided in this application can move synchronously with the laser cutting head, allowing the negative pressure space it generates to effectively cover the real-time cutting point, fully drawing smoke away, ensuring the completeness and thoroughness of smoke extraction, reducing smoke residue, improving smoke extraction efficiency, and reducing the risk of smoke hazard to personnel health.

[0022] Preferably, both ends of the suction traction pipe 5 are sealed to the air guide pipe 44 and the air inlet 611 of the main filter chamber 61 via flange structures. Preferably, the input end of the extension and telescopic pipe 51 of the suction traction pipe 5 is connected to the port of the air guide pipe 44. Preferably, an air pump 52 is connected to the output end of the extension and telescopic pipe 51, which can directionally transfer flue gas along the pipe path defined by the extension and telescopic pipe 51 after it passes through the internal chamber of the cavity ring 42. Specifically, the outlet end of the air pump 52 is connected to the inlet end of the first filter assembly 6. Specifically, both ends of the extension and telescopic pipe 51 are connected to the air guide pipe 44 and the inlet port of the air pump 52 via sealing flanges. Preferably, the outlet end of the air pump 52 is also connected to the input end of the air inlet 611 via a sealing flange structure. Preferably, the air pump 52 is an HC-VF-30 titanium alloy impeller pump specifically designed for negative pressure traction and exhaust of smoke and dust, with a built-in self-cleaning scraper system, which is particularly suitable for the recovery of metal fumes from cutting machine tools.

[0023] Preferably, the first filter assembly 6 includes a main filter chamber 61, an intercepting filter plate 62, an adsorption filter plate 63, and a slag discharge mechanism 64. Preferably, the main filter chamber 61 is detachably provided with an intercepting filter plate 62 and an adsorption filter plate 63, which can divide its internal space into multiple sections along the flue gas flow direction and perform multi-stage filtration of the passing flue gas. Specifically, the intercepting filter plate 62 and multiple adsorption filter plates 63 are arranged parallel to each other in the main filter chamber 61 at intervals to perform multi-stage filtration of the directional flue gas. Preferably, the edges of the intercepting filter plate 62 and multiple adsorption filter plates 63 are provided with corner connecting seats or other structures, thereby limiting the working position of the intercepting filter plate 62 and multiple adsorption filter plates 63 in the main filter chamber 61 by means of snap-fit ​​installation or bolt positioning connection. Preferably, a slag discharge mechanism 64 penetrating the bottom wall of the main filter chamber 61 is provided at the bottom of the inlet side of the intercepting filter plate 62. The intercepting filter plate 62 provided in this application can intercept and screen out particulate matter, and the adsorption filter plate 63 can adsorb and remove VOCs, ozone, and odors, thereby improving the filtration effect on harmful components in flue gas. The intercepting filter plate 62 can intercept and recycle particulate matter such as metal substrate fragments to avoid pollution and harm from metal dust, and can also realize the recycling and reuse of substrates. The slag discharge mechanism 64 provided in this application can periodically discharge the substrate fragments that have been intercepted and accumulated by the intercepting filter plate 62, thereby preventing substrate accumulation from obstructing the filter screen of the intercepting filter plate 62 and improving the efficiency of continuous filtration.

[0024] Preferably, an air inlet pipe head 611 is inserted into the side of the main filter chamber 61, enabling its internal space to communicate with the air outlet of the air pump 52. Preferably, an air outlet pipe head 612 communicating with its internal space and an end cap 614 sealing the side opening of the main filter chamber 61 are respectively provided on the bottom and side surfaces of the main filter chamber 61 away from the air inlet pipe head 611. Preferably, a counterweight receiving secondary chamber 613 capable of accommodating part of the slag discharge mechanism 64 is also provided on the bottom surface of the main filter chamber 61. By providing a threaded connection and a sealing ring on the end cap 614, this application allows the main filter chamber 61 to be disassembled in a non-working state, facilitating the cleaning, maintenance, and replacement of the internal interception filter plate 62 and adsorption filter plate 63.

[0025] Preferably, the intercepting filter plate 62 includes a mounting frame and a filter screen or filter non-woven fabric disposed within the frame, which can be replaced as needed to filter out debris of different particle sizes. The intercepting filter plate 62 provided in this application can intercept particulate matter, and the metal substrate usually has weak electrical properties during the cutting process, which leads to an increase in the total weight of the intercepted particles as they gradually accumulate. As a result, during the suction working interval, large-weight and large-volume debris and particle clumps can roll down along the intercepting filter plate 62 and gradually accumulate on the bottom surface of the inner cavity of the main filter chamber 61. If this is not cleaned in time, it will cause the flow channel cross-section to become smaller, reducing the actual flowable cross-section of the intercepting filter plate 62 and affecting the filtration efficiency.

[0026] Preferably, the adsorption filter plate 63 includes a perforated frame and activated carbon filled in the space within the frame, so that VOCs, ozone and odors can be adsorbed and filtered out by the activated carbon when the flue gas flows through the gaps in the activated carbon.

[0027] Preferably, the slag discharge mechanism 64 includes a through channel 641 penetrating the bottom wall of the main filter chamber 61 and a slag collection box 642 connected to the bottom port of the through channel 641. Preferably, a deflection baffle 643 is provided inside the through channel 641, connected to a deflection shaft 644 rotatably embedded in its side wall, and dividing the through cavity formed by the through channel 641. Preferably, the deflection baffle 643 penetrates the side wall of the through channel 641 and is inserted into the plate of the counterweight receiving secondary cavity 613, and a counterweight block 645 is provided to limit the initial working posture of the deflection baffle 643. Specifically, a through hole is provided between the through channel 641 and the counterweight receiving secondary cavity 613, and the deflection shaft 644 is rotatably inserted into the through hole, so that the deflection shaft 644 can drive the deflection baffle 643 to deflect. Preferably, the through channel 641 is further provided with a maximum counterclockwise deflection amount of the deflection baffle 643, enabling the deflection baffle 643 to effectively and variably isolate the through channel 641. Preferably, the through channel 641 is integrally connected to the slag collection box 642 by welding or other methods to ensure structural integrity and airtight connectivity. Preferably, the slag collection box 642 is threaded with a removable bottom plate that seals the bottom opening, allowing operators to clean up debris as needed, facilitating the recycling of the substrate. During the filtration process, debris intercepted by the filter plate 62 gradually accumulates on the deflector baffle 643, increasing its weight on the side plate of the deflector baffle 643 within the through channel 641. When this weight continues to increase and exceeds the upward force provided by the counterweight 645, the deflector baffle 643 deflects clockwise, causing the accumulated debris to slide down and transfer to the slag collection box 642. This achieves the periodic transfer of intercepted debris within the flue gas flow space, preventing accumulated debris from obstructing the flow channel. This application sets it in a deflection configuration to facilitate the limitation of flue gas flow direction and prevent the flue gas from blowing away accumulated particles, thus avoiding dust and other adverse phenomena.

[0028] Preferably, the second filter assembly 7 includes a boot-shaped reservoir 71 for storing wash water capable of dissolving acidic gases such as NOx and capturing hydrophilic oxide residues, and an air inlet pipe 72 inserted into the boot-shaped reservoir 71. Specifically, an air inlet pipe 72 connected to an air outlet head 612 is inserted into the top surface of the enclosed cavity of the boot-shaped reservoir 71. Preferably, the air inlet pipe 72 connected to the air outlet head 612 is connected via a sealing flange. Preferably, the wash water is pure water, which can be changed by the operator according to the actual working time. For example, if the single cycle cutting time does not exceed 2 hours, the water is changed once before each use; when a longer cycle of use is required, the wash water is changed every 2 hours to ensure that the wash water has a high dissolving capacity.

[0029] Preferably, the electrical components involved in this application, such as the annular heat exchange plate 31, the lifting adjustment rod 41, and the air pump 52, are all electrically connected to the controller and the power supply. The control method of this application is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is only used to protect the mechanical device and its mechanical structural features. Therefore, this utility model will not explain the control method and circuit connection in detail.

[0030] For surface connections between components not explicitly specified in this application, conventional bolt connections, snap-fit ​​connections, or fixed connections such as welding can be used. As these are conventional connection methods, this application will not elaborate further on this part. Specifically, the connecting ends of the assembled components all form flange structures, and the two flange structures are connected by bolts, gaskets, or other structures.
