Description

Technical Field

[0001] This invention relates to the field of strip laser cutting technology, and in particular to a strip laser cutting processing equipment. Background Technology

[0002] Laser cutting utilizes a focused, high-power-density laser beam to irradiate the workpiece, causing the irradiated material to rapidly melt, vaporize, ablate, or reach its ignition point. Simultaneously, a high-speed airflow coaxial with the beam blows away the molten material, thereby cutting the workpiece. As the beam moves across the material, it continuously forms very narrow kerfs (e.g., about 0.1 mm), completing the cutting of the material. It is one of the thermal cutting methods.

[0003] During product manufacturing, laser cutting is performed according to the product processing requirements. Currently, laser cutting machines are typically used to cut the strip when it is conveyed to the cutting process. This process generates fumes, exhaust gases, and cutting debris. However, most current laser cutting devices for strip processing lack the ability to collect these fumes and debris. During use, the following shortcomings have been gradually discovered:

[0004] (1) The generated smoke, dust and waste will directly affect the working environment in the workshop, and the smoke and dust will harm the health of workers. The direct discharge without treatment will also pollute the environment, which is extremely environmentally unfriendly.

[0005] (2) The fumes that are not removed in time will affect the penetration of the laser, and the waste that is not cleaned up in time will also affect the cutting and processing of the product, both of which will affect the processing quality of the strip product.

[0006] (3) Frequent machine shutdowns are required for waste cleaning, which affects product processing efficiency, is labor-intensive, time-consuming and labor-intensive, and the cost of manual waste cleaning is also high. Summary of the Invention

[0007] In order to overcome the deficiencies of the prior art as mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this invention.

[0008] Specifically, the technical problem to be solved by the present invention is to provide a strip laser cutting processing equipment to solve the problem that the current strip laser cutting device does not have the function of collecting the smoke and dust generated during the processing and the waste chips generated during the cutting process. The smoke and dust will affect the working environment in the workshop and the processing quality of the products. The smoke and dust will harm the health of workers and pollute the environment. The cleaning of waste chips is time-consuming, labor-intensive and costly.

[0009] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0010] A laser cutting equipment for strip materials includes a housing body, with strip material inlets on both sides of the housing body. A laser cutting machine is fixedly installed on the top of the housing body using a light-shielding component. A honeycomb plate for supporting the strip material is provided inside the housing body. A U-shaped suction cavity and a blowing component are provided above the honeycomb plate inside the housing body. A plurality of smoke suction ports are provided on the inner side of the U-shaped suction cavity.

[0011] The cover body is also fixedly installed with a flue gas exhaust pipe that is connected to the U-shaped suction cavity. The exhaust end of the flue gas exhaust pipe is connected to a flue gas delivery pipe. Downstream of the flue gas delivery pipe, a flue gas filter and a suction volume adjustment device are connected in sequence.

[0012] The cover body is provided with a waste exhaust pipe below the honeycomb panel. The waste exhaust pipe has a waste collection hopper corresponding to the honeycomb panel. The waste exhaust pipe is fixedly installed on the cover body through its waste collection hopper, and the exhaust pipe is connected to a waste air delivery pipe.

[0013] As an improved technical solution, the cover body is provided with a guide roller and a sealing plate at the material conveyor opening. The guide roller is rotatably mounted on the cover body, and the sealing plate has a first strip hole. The sealing plate is fixedly mounted on the cover body by an anti-detachment screw that passes through the first strip hole.

[0014] As an improved technical solution, the light-shielding assembly includes a lower light-shielding tube, an upper light-shielding tube, and a positioning knob. The lower light-shielding tube is fixedly installed on the top of the housing body. The upper light-shielding tube is slidably inserted into the lower light-shielding tube in the vertical direction. The lower light-shielding tube has several second strip-shaped holes. The positioning knob passes through the second strip-shaped holes and is threaded onto the upper light-shielding tube. The laser cutting machine is fixedly installed on the top of the upper light-shielding tube.

[0015] As an improved technical solution, a front cover plate is installed at the end of the cover body away from the flue gas exhaust pipe using a nitrogen spring. The front cover plate is provided with a first handle for easy opening and closing. The honeycomb panel is slidably inserted into the cover body, and a limiting pin is inserted at the end of the cover body to limit the position of the honeycomb panel.

[0016] As an improved technical solution, the U-shaped suction cavity has an avoidance opening corresponding to the material conveyor belt inlet;

[0017] The U-shaped suction cavity is detachably mounted with sealing plates for sealing the two side chambers. The sealing plates are located on both sides of the U-shaped suction cavity near the connection end.

[0018] As an improved technical solution, the U-shaped suction cavity is provided with a sealing plate insertion slot, and the sealing plate is installed in the U-shaped suction cavity through the sealing plate insertion slot;

[0019] The U-shaped suction cavity is also provided with a baffle for sealing the flue gas intake port. The baffle is installed on the U-shaped suction cavity using several adjustment components.

[0020] As an improved technical solution, the blowing assembly is provided in two sets, and the two sets of blowing assemblies are respectively arranged close to both sides of the cover body;

[0021] The blowing assembly includes an air blowing pipe fixedly installed inside the housing body. The air blowing pipe has several movable hoses along its length, and each movable hose is provided with a switch valve.

[0022] As an improved technical solution, the flue gas filtration device includes a filter tube body connected to the flue gas delivery pipe, a flue gas filter box on the filter tube body, a filter assembly detachably installed on the flue gas filter box, and a box body connecting part on each side of the filter tube body. The box body connecting part is a funnel-shaped structure with a gradually narrowing diameter along the direction away from the flue gas filter box.

[0023] As an improved technical solution, the filter assembly includes a filter frame and a filter screen. The filter screen is fixedly installed on the filter frame. The filter frame has a second handle for easy removal and insertion. The filter frame is slidably installed on the flue gas filter box, and the filter frame is fixedly connected to the flue gas filter box by locking screws.

[0024] As an improved technical solution, the air volume regulating device includes a valve tube body connected to the filter tube body. A rotating shaft driven by a driving device is rotatably mounted on the valve tube body. A valve plate is fixedly mounted on the rotating shaft. The valve plate is located inside the valve tube body and is adapted to the inner diameter of the valve tube body.

[0025] After adopting the above technical solution, the beneficial effects of the present invention are:

[0026] (1) The material strip laser cutting processing equipment adjusts the suction volume through the suction volume adjustment device. During operation, the material strip is fed into and discharged from the material strip inlets on both sides of the cover body. The material strip entering the cover body is supported by the honeycomb plate and laser-cut by the laser cutting machine. The blowing assembly blows air at the laser cutting location of the material strip. The smoke and exhaust gas generated during the processing are blown away and dispersed by the blowing assembly and then sucked into the U-shaped suction cavity through the smoke inlet. The flue gas is transported to the flue gas filtration device via the flue gas extraction pipe and flue gas conveying pipe. The flue gas filtration device effectively filters out any waste debris that may be present in the flue gas. Finally, the flue gas passes through the air volume regulating device and enters the subsequent process for centralized treatment before being discharged. During the processing, the waste debris cut by the laser cutting machine is drawn to the area below the honeycomb panel through the waste debris extraction pipe. The honeycomb panel not only supports the material strip but also facilitates the waste debris cut during the cutting process to fall through its mesh below it. The waste debris is then transported to the subsequent process for centralized collection and treatment via the waste debris extraction pipe and waste debris conveying pipe.

[0027] This strip laser cutting equipment enables timely and effective centralized collection and treatment of fumes and waste generated during the laser cutting process. This avoids the impact of fumes and waste on the laser cutting of products and the influence of fumes leakage on the workshop environment, ensuring that the processing quality of the workpiece remains unaffected. Centralized collection and treatment of fumes prevents harm to workers' health and environmental pollution, making strip laser cutting safer and more environmentally friendly. Centralized collection and treatment of waste eliminates the need for frequent machine shutdowns for manual waste cleaning, improving workpiece processing efficiency and effectively replacing manual labor while reducing waste cleaning costs.

[0028] (2) The cover body is provided with a guide roller and a sealing plate at the material belt passage position. The guide roller can guide and convey the material belt. The sealing plate is used to adjust the size of the material belt passage. The sealing plate can be adjusted by loosening the anti-detachment screw. After adjustment, the anti-detachment screw can be tightened again. The adjustment operation is simple and convenient.

[0029] (3) The light-shielding component can not only realize the installation of the laser cutting machine and play the function of shielding the laser cutting light, but also realize the flexible adjustment of the installation height of the laser cutting machine according to the needs of laser cutting processing. The installation height of the laser cutting machine can be adjusted by loosening the positioning knob, and the current installation height of the laser cutting machine can be fixed by tightening the positioning knob after adjustment. The adjustment operation is simple and convenient. In addition, the light-shielding component also has a sealing function, which can prevent the leakage of smoke.

[0030] (4) A front cover plate is installed at the end of the cover body away from the flue gas exhaust pipe using a nitrogen spring. The honeycomb plate is slidably inserted into the cover body, and a limiting pin is inserted at the end of the cover body to limit the honeycomb plate. Open the front cover plate and then pull out the limiting pin to remove the honeycomb plate from the cover body, which facilitates the cleaning and replacement of the honeycomb plate. After the honeycomb plate is inserted into place, the limiting pin is reinserted, and finally the front cover plate is closed. This makes the disassembly and assembly of the honeycomb plate simple and convenient.

[0031] (5) The detachable sealing plate is provided. When in use, according to the processing requirements, one side of the U-shaped suction cavity is sealed with the sealing plate, so that only the connecting end of the U-shaped suction cavity and the other side cavity are connected to the flue gas exhaust pipe to form an L-shaped suction cavity. At the same time, the sealing plate is adjusted so that an air inlet is left at the material conveyor on the side close to the closed cavity of the U-shaped suction cavity, and a material conveyor gap is formed at the material conveyor on the other side through the sealing plate, which is only for the material conveyor to pass through. During operation, air is introduced from the air inlet on one side, blown by the blowing component, and sucked by the L-shaped smoke area of ​​the U-shaped suction cavity. It can timely remove the smoke and exhaust gas generated during the laser cutting process, and has a good effect on smoke absorption and collection.

[0032] (6) The sealing plate is installed in the U-shaped suction cavity through the sealing plate insertion slot. By opening the top cover of the U-shaped suction cavity, the sealing plate can be pulled out and inserted, making the disassembly and assembly of the sealing plate simple and convenient.

[0033] (7) The U-shaped suction cavity is provided with several flue gas suction ports, which can not only suck away the smoke and dust, but also prevent the waste from laser cutting from entering the U-shaped suction cavity. Furthermore, the size of the flue gas suction port can be adjusted by using the baffle installed on the adjustment component, thereby adjusting the suction volume of the U-shaped suction cavity.

[0034] (8) The blowing assembly provided can blow air to the laser cutting processing position of the strip by adjusting the air blowing pipe, and blow away the smoke generated during the laser cutting process in time, so as to avoid the smoke from affecting the penetration of the laser and further ensure the quality of laser cutting processing of the strip.

[0035] (9) The flue gas filtration device provided can effectively filter waste and other materials that may be contained in the flue gas, and prevent the debris from entering the subsequent flue gas treatment equipment. In addition, since the filter assembly will affect the flow rate of the flue gas to a certain extent when filtering the flue gas, the filter tube is provided with a box connection part on both sides of the flue gas filter box, which increases the flow surface area at the position of the filter assembly, which can offset the effect of the filter assembly on the reduction of the flue gas flow rate, and ensure that the filter assembly will not affect the overall flow rate of the flue gas while filtering the flue gas.

[0036] (10) The filter assembly is provided, the filter screen filters the flue gas, the filter screen frame is fixedly connected to the filter box body by locking screws, and the filter screen frame has a handle for easy removal and insertion. The filter assembly can be completely disassembled by loosening the locking screws, which facilitates the regular cleaning of the filter assembly. The disassembly and assembly of the filter assembly is simple and convenient.

[0037] (11) The suction volume adjustment device is simple in structure. It can automatically and flexibly adjust the suction volume of the pipeline by driving the valve plate to flip through the drive device. Attached Figure Description

Loosening the locking knob 20 allows the baffle 19 to slide. By sliding the baffle 19, the size of the flue gas suction port 1701 can be adjusted, thereby adjusting the suction volume of the U-shaped suction cavity 17. After adjustment, simply tighten the locking knob 20 again. The adjustment operation is simple and convenient.

[0080] Two sets of air blowing assemblies are provided, and the two sets of air blowing assemblies are respectively arranged close to both sides of the housing body. In this embodiment, the air blowing assembly includes an air blowing pipe 22 fixedly installed inside the housing body. Several movable hoses 23 are provided along the length of the air blowing pipe 22, and each movable hose 23 is provided with a switch valve 2301, which controls the opening and closing of each individual movable hose 23. This air blowing assembly can achieve air blowing at the laser cutting position of the strip by adjusting the air blowing pipe 22, and promptly blow away the fumes generated during the laser cutting process, avoiding the fumes affecting the penetration of the laser, and further ensuring the quality of laser cutting of the strip.

[0081] In this embodiment, the flexible hose 23 is a MISUMI flexible hose.

[0082] In this embodiment, a corresponding blower fixing member 24 is fixedly installed inside the cover body, and the air blowing pipe 22 is fixedly installed inside the cover body using the blower fixing member 24. A through hole 102 corresponding to the air receiving end of the air blowing pipe 22 is opened at one end of the cover body near the flue gas exhaust pipe 25, so that the air supply pipe can pass through the through hole 102 and communicate with the air blowing pipe 22.

[0083] In this embodiment, a tool insertion hole 401 is provided on the side glass 4, which corresponds to the fastening bolt of the blower fixing member 24. The tool is inserted into the cover body through the tool insertion hole 401, the blower fixing member 24 is loosened, and then the front cover plate 2 is opened, so that the blower tube can be rotated and adjusted, thereby realizing the angle adjustment of the entire row of movable hoses 23. After the adjustment is completed, the fastening bolt of the blower fixing member 24 is tightened again, so that the current adjustment angle can be fixed.

[0084] The flue gas filtration device includes a filter tube 28 connected to the flue gas delivery pipe 27. The filter tube 28 has a flue gas filter box 2801. A filter assembly 29 is detachably installed on the flue gas filter box 2801. The filter tube 28 has a box connection part 2802 on both sides of the flue gas filter box 2801. The box connection part 2802 is a funnel-shaped structure with a gradually narrowing diameter along the direction away from the flue gas filter box 2801.

[0085] This flue gas filtration device can effectively filter out any debris or other contaminants that may be present in the flue gas, preventing these particles from entering subsequent flue gas treatment equipment. Furthermore, since the filter assembly 29 affects the flue gas flow rate to some extent during filtration, the filter tube 28 has box connection portions 2802 on both sides of the flue gas filter box 2801. This increases the flow surface area at the location of the filter assembly 29, offsetting the effect of the filter assembly 29 on reducing the flue gas flow rate. This ensures that the filter assembly 29 achieves flue gas filtration without affecting the overall flue gas flow rate.

[0086] In this embodiment, both the flue gas filter box 2801 and the box body connecting part 2802 are integrally formed structures of the filter tube body 28.

[0087] The filter assembly 29 includes a filter frame 2901 and a filter screen 2902. The filter screen 2902 is fixedly installed on the filter frame 2901. The filter frame 2901 has a second handle 2903 for easy removal and installation. The filter frame 2901 is slidably installed on the flue gas filter box 2801 and is fixedly connected to the flue gas filter box 2801 by a locking screw 30. With this filter assembly 29, the filter screen 2902 filters the flue gas, and the filter frame 2901 is fixedly connected to the filter box by a locking screw 30. The filter frame 2901 has a handle for easy removal and installation. Loosening the locking screw 30 allows the filter assembly 29 to be completely disassembled, facilitating regular cleaning of the filter assembly 29. The disassembly and assembly of the filter assembly 29 is simple and convenient.

[0088] In this embodiment, the locking screw 30 is a resin knurled screw, which is convenient for manual tightening.

[0089] The air volume regulating device includes a valve tube 31 connected to the filter tube 28. A rotating shaft 37 driven by a drive device is rotatably mounted on the valve tube 31. A valve plate 38 is fixedly mounted on the rotating shaft 37. The valve plate 38 is located inside the valve tube 31 and is adapted to the inner diameter of the valve tube 31. This air volume regulating device has a simple structure. By driving the valve plate 38 to rotate through the drive device, the air volume of the pipeline can be automatically and flexibly adjusted.

[0090] In this embodiment, the rotating shaft 37 is rotatably mounted on the valve pipe body 31 using a bearing seat.

[0091] In this embodiment, the valve body 31 has a mounting base 3101. The driving device includes a drive motor 32 fixedly mounted on the mounting base 3101. A drive pulley 33 is keyed to the output shaft of the drive motor 32. A driven pulley 34 is keyed to one end of the rotating shaft 37. A synchronous belt 35 is wound between the drive pulley 33 and the driven pulley 34. The drive pulley 33 and the driven pulley 34 are connected by transmission through the synchronous belt 35. When the drive motor 32 works, it drives the rotating shaft 37 to rotate through the drive pulley 33, the driven pulley 34 and the synchronous belt 35, thereby realizing the flipping drive of the valve plate 38.

[0092] In this embodiment, a valve cover 36 covering the driving pulley 33, the driven pulley 34 and the timing belt 35 is fixedly installed on the mounting base 3101. The valve cover 36 can effectively protect the transmission part of the drive device and prevent dust and impurities from entering.

[0093] In this embodiment, a dial 39 is installed on the valve body 31 at the other end of the rotating shaft 37. The other end of the rotating shaft 37 passes through the dial 39 and is equipped with a valve pointer 40. Through the dial 39 and the valve pointer 40, the suction volume of the valve body 31 can be displayed intuitively, which makes it easy for operators to understand the flue gas circulation status in real time.

[0094] In order to install the valve pointer 40, in this embodiment, the other end of the rotating shaft 37 has an insertion part, and the valve pointer 40 has an insertion hole corresponding to the insertion part. The valve pointer 40 is fitted onto the rotating shaft 37 through the insertion hole and the insertion part.

[0095] In this embodiment, a V-shaped positioning groove 3701 is provided on the outer surface of the rotating shaft 37 along its axial direction. The valve plate 38 is fitted onto the rotating shaft 37, and a plurality of positioning mounting holes 3801 are provided on the valve plate 38. A tapered set screw 41 is installed in the internal thread of the positioning mounting hole 3801. The valve plate 38 is fixedly installed on the rotating shaft 37 through the V-shaped positioning groove 3701 and the tapered set screw 41, thereby realizing the positioning and fixed installation of the valve plate 38.

[0096] The inner wall of the valve body 31 is provided with at least one limiting protrusion 3102 for limiting the flipping of the valve plate 38; in this embodiment, two limiting protrusions 3102 are provided on the inner wall of the valve body 31. The limiting protrusions 3102 can limit the flipping of the valve plate 38 when the air duct is closed.

[0097] In this embodiment, the waste collection hopper 4201 has an inverted conical structure, which facilitates the collection of waste.

[0098] In this embodiment, an opening is provided on the cover body at the same direction end of the flue gas exhaust pipe 25. The opening facilitates the insertion of the waste collection hopper 4201 of the waste exhaust pipe 42 into the cover body, providing convenience for the disassembly and assembly of the waste exhaust pipe 42. During regular inspection and maintenance, the front cover plate 2 is opened, and then the limiting pin 16 is pulled out, so that the honeycomb plate 15 can be pulled out. After the honeycomb plate 15 is pulled out, the mounting bolts for installing the waste collection hopper 4201 are removed, so that the waste exhaust pipe 42 can be pulled out from the cover body through the opening.

[0099] Based on the above structure, the strip laser cutting processing equipment adjusts the suction volume through a suction volume regulating device. During operation, the strip is fed into and discharged from the cover body through the strip feed ports 101 on both sides of the cover body. The strip entering the cover body is supported by the honeycomb plate 15 and laser-cut by the laser cutting machine 14. The blowing assembly blows air onto the laser-cutting location of the strip. The smoke and exhaust gas generated during processing are promptly blown away and dispersed by the blowing assembly and then drawn into the U-shaped suction cavity 17 through the smoke inlet 1701. The flue gas is transported to the flue gas filtration device via the flue gas extraction pipe 25 and the flue gas conveying pipe 27. The flue gas filtration device effectively filters any waste debris that may be present in the flue gas. Finally, the flue gas passes through the suction volume regulating device and enters the subsequent process for centralized treatment before being discharged. During the processing, the waste debris cut by the laser cutting machine 14 is drawn to the area below the honeycomb plate 15 by the waste debris extraction pipe 42. The honeycomb plate 15 supports the material strip and facilitates the waste debris cut during the cutting process to fall below it through its mesh. The waste debris is then transported to the subsequent process for centralized collection and treatment via the waste debris extraction pipe 42 and the waste debris conveying pipe 43.

[0100] This strip laser cutting equipment enables timely and effective centralized collection and treatment of fumes and waste generated during the laser cutting process. This avoids the impact of fumes and waste on the laser cutting of products and the influence of fumes leakage on the workshop environment, ensuring that the processing quality of the workpiece remains unaffected. Centralized collection and treatment of fumes prevents harm to workers' health and environmental pollution, making strip laser cutting safer and more environmentally friendly. Centralized collection and treatment of waste eliminates the need for frequent machine shutdowns for manual waste cleaning, improving workpiece processing efficiency and effectively replacing manual labor while reducing waste cleaning costs.
