Description

Technical Field

[0001] This application relates to the field of steel plate cutting and processing technology, and in particular to a laser cutting machine for steel plate processing. Background Technology

[0002] Currently, in the field of modern industrial materials processing, laser cutting technology has become a widely used advanced processing method due to its unique processing principle and significant advantages. Its core working mechanism is to emit a high-power-density laser beam from a laser, which is focused by an optical system to form a laser focal point. When the power density at the focal point reaches or exceeds the thermal ignition point of the material being cut, the material will rapidly melt and evaporate to form a hole. At the same time, high-pressure gas coaxial with the beam blows the molten material out in time, thereby forming a kerf, and finally achieving precise cutting of the material. Based on this principle, laser cutting has multiple core functions such as high efficiency and precision, wide range of applicable materials, strong processing flexibility, environmental protection and energy saving, and effective reduction of production costs. It occupies an increasingly important position in industrial production and has broad application prospects. To further optimize the practical application effect of laser cutting, various specialized devices have emerged in related technical fields. For example, a laser cutting device for steel plate processing disclosed in Chinese Patent No. CN222957729U includes a support base. First limiting slide rails are fixedly installed on both sides of the upper end of the support base. A movable support plate is movably connected to the upper end of the slide rails. First motors are provided on both sides of the front end of the movable support plate. The motor drive shaft passes through the support plate and is connected to a first gear. The gear meshes with a first rack. The upper end of the support plate is also provided with a cutting support groove for placing the steel plate. At the same time, a cutting frame is fixedly supported on the outer side of the middle of the support base. A second limiting slide rail is installed on the top of the cutting frame. With this structural design, the device can realize linear movement adjustment of the laser cutting head in all directions (front, back, left, right, up, and down). It can also adjust the cutting angle of the laser cutting head horizontally and vertically, showing certain practicality in terms of cutting position and angle adjustment. However, in actual industrial applications, this type of laser cutting device still has obvious defects and shortcomings, especially in the fume treatment stage. During laser cutting, the high heat generated by the interaction of high-power laser with the material produces a large amount of metallic fumes. If these fumes permeate the factory workshop, they will seriously harm the health of the operators. Although some existing laser cutting equipment has been equipped with corresponding fume extraction structures, the laser cutting operation usually requires linear displacement to complete the entire cutting process. However, the existing fume extraction and purification structures cannot move synchronously with the lateral displacement of the laser cutting head, which makes it easy for fumes to leak and escape during the cutting process, making it difficult to effectively capture the fumes. In addition, when the existing equipment uses negative pressure fume extraction, dust and large particulate impurities in the air will enter the purification equipment along with the fumes, which can easily clog the filter screen and seriously affect the overall fume extraction efficiency and purification effect of the equipment. The existence of these problems means that there is still a lot of room for improvement in the actual use of existing laser cutting devices, and targeted improvements are urgently needed to solve the above-mentioned fume treatment problems.

[0014] In summary, this application includes the following beneficial technical effects: 1. During the application of this technical solution, by setting up a following smoke extraction mechanism, the suction component and the laser cutting mechanism can be linked during use. The suction bucket can move synchronously with the lateral displacement of the cutting mechanism, and at the same time, it can rotate flexibly with the help of the transmission structure, always accurately targeting the core area of ​​the smoke generated by laser cutting, avoiding the leakage and escape of smoke due to the fixed suction structure. This achieves the effect of dynamically capturing smoke and improving the smoke collection rate, solving the problem of the existing technology where the smoke extraction structure and the cutting head are not synchronized and smoke permeates the workshop, endangering the health of operators. This following design does not require additional power to drive the movement of the suction component, but only relies on the displacement of the cutting mechanism to achieve synchronous action, which simplifies the structural design and ensures real-time coordination between smoke extraction and cutting, improving the overall operating efficiency of the equipment. 2. During the application of this technical solution, by setting up a linkage cleaning structure, the cleaning component and the filter can be driven to move relative to each other by the kinetic energy of the suction component following the movement of the cutting mechanism. The cleaning component can brush away the impurities attached to the surface of the filter in real time without the need for an additional cleaning power source, thereby achieving the effect of automatically cleaning the filter and avoiding filter clogging. This solves the problems of existing technologies where negative pressure smoke can easily bring in impurities that clog the filter, requiring frequent shutdowns for manual cleaning or replacement of the filter, and affecting the continuity of production. This linkage cleaning method is carried out synchronously with the following smoke action, completing filter maintenance while capturing smoke, ensuring that the smoke conveying channel is always unobstructed and maintaining stable smoke treatment efficiency. 3. During the application of this technical solution, by coordinating the following smoke extraction mechanism and the linkage cleaning structure, the smoke extraction, following, and cleaning can be operated synchronously in a three-in-one manner. When the suction hopper moves with the cutting mechanism to capture smoke, the cleaning component simultaneously uses the kinetic energy of movement to clean the filter screen. This ensures the timeliness and effectiveness of smoke capture and avoids the decrease in smoke extraction efficiency caused by filter screen blockage. As a result, the overall effect of smoke treatment is improved and the frequency of equipment maintenance is reduced. This solves the problems of existing technologies where smoke extraction and filter screen cleaning are independent, smoke escape and filter screen blockage coexist, and the overall equipment operation effect is poor. At the same time, in conjunction with the subsequent purification module, it further ensures that the smoke emission meets the standards and meets the dual requirements of environmental protection and efficiency in industrial production.

[0017] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0018] This application discloses a laser cutting machine for steel plate processing. For example... Figure 1-8 As shown, the system includes a base frame 1, with conveyor frames 2 fixedly installed on both sides of the top of the base frame 1. Conveyor belts 3 are rotatably connected to the inner side of the conveyor frames 2. A base plate 4 is fixedly installed in the middle of the inner side of the base frame 1.

Suction modules 9 are fixedly installed on both sides of the moving end of the displacement module 6. The output end of the suction module 9 is connected to the input end of the purification module 7. The suction module 9 includes a side frame 91, which is fixedly installed on both sides of the moving end of the displacement module 6. A mounting bracket 92 is fixedly installed on the outer side of the side frame 91. A rotary joint 93 is rotatably connected to the upper inner side of the mounting bracket 92. The top output end of the rotary joint 93 is connected to the purification module 7. A suction hopper 94 is fixedly installed at the bottom of the rotary joint 93. A filter screen 95 is fixedly installed inside the suction hopper 94. Both suction hoppers 94 are arranged at an angle on both sides of the laser cutting mechanism 8.

The cleaning end of the cleaning component 96 is attached to the outer surface of the filter screen 95 inside the suction hopper 94. A transmission mechanism 97 is fixedly installed on the top of the mounting frame 92. During the application of this device, by setting the conveyor frame 2 and the conveyor belt 3 on both sides of the top of the base frame 1, the steel plate to be processed can be transported to the base plate 4 in the middle of the inner side of the base frame 1, providing a stable placement base for steel plate cutting. By setting the mounting frame 5 on the top of the base plate 4, a displacement module 6 can be mounted. The moving end of the displacement module 6 can drive the laser cutting mechanism 8 at the bottom to adjust its position. The displacement module 6 is positioned to precisely cut the steel plate. Simultaneously, the suction modules 9 on both sides of the moving end of the displacement module 6 can move synchronously. When the laser cutting mechanism 8 is working, the suction modules 9 collect the fumes generated during cutting through the suction hopper 94 and transport them to the purification module 7 on the top side of the displacement module 6 for processing. In the suction module 9, the rotary joint 93 at the upper inner side of the mounting bracket 92 ensures flexible rotation of the suction hopper 94. The filter screen 95 inside the suction hopper 94 performs preliminary filtration of impurities in the fumes. The cleaning... Component 96 can be attached to the outer surface of filter screen 95 to clean filter screen 95 during the operation of suction hopper 94. The transmission mechanism 97 on the top of mounting bracket 92 can assist in adjusting the angle and position of suction hopper 94. Through the coordinated cooperation of each module, the overall structure can not only achieve stable conveying and precise cutting of steel plate, but also collect and process the fumes generated during cutting in a timely manner, reducing the impact of fumes on the environment and operators. At the same time, the cleaning design of filter screen 95 can maintain the stable operation of suction module 9, improving the overall performance and durability of the equipment.

[0019] Please refer to Figures 5-8The transmission mechanism 97 includes a bevel gear ring 971, a fixing plate 972, and a transmission assembly 973. The transmission assembly 973 is fixedly installed on the upper outer side of the mounting frame 5. The bevel gear ring 971 is fixedly installed on the outer surface of the rotary joint 93. The fixing plate 972 is fixedly installed on the top of the mounting frame 92. A shaft 974 is fixedly installed on the upper end of the fixing plate 972. A bevel gear 975 is rotatably connected to the side of the shaft 974 near the bevel gear ring 971. The bevel gear 975 and the bevel gear ring 971 are meshed. A spur gear 976 is fixedly connected to the end of the shaft 974 away from the bevel gear 975. The spur gear 976 is connected to the transmission assembly 973. The transmission assembly 973 includes an outer frame 9731. 9731 is fixedly installed on both upper ends of the mounting frame 5. Mounting strips 9732 are fixedly installed on both ends of the inner side of the outer mounting frame 9731. Spur racks 9733 are fixedly installed on the inner side of the mounting strips 9732. The spur racks 9733 and spur gears 976 mesh with each other. The cleaning component 96 includes a fixed shaft 961, which is fixedly installed at the bottom of the mounting frame 92. Strip plates 962 are fixedly connected to the outer surface of the fixed shaft 961 in a ring at equal intervals. A cleaning soft brush plate 963 is fixedly connected to the side of the strip plate 962 closest to the filter screen 95. The inner side of the cleaning soft brush plate 963 is in contact with the outer surface of the filter screen 95. The filter screen 95 has a conical shape. This device... During application, by setting up a transmission mechanism 97 and a transmission component 973, when the displacement module 6 drives the suction module 9 to move, the spur rack 9733 on the inner mounting strip 9732 of the outer frame 9731 in the transmission component 973 can mesh with the spur gear 976 at one end of the shaft 974, driving the shaft 974 and the bevel gear 975 at the other end to rotate. The bevel gear 975 then meshes with the bevel ring 971 on the outer surface of the rotary joint 93, thereby driving the rotary joint 93 to rotate, realizing flexible adjustment of the angle of the suction hopper 94, allowing the suction hopper 94 to be better aligned with the area where the cutting smoke is generated. At the same time, by setting up a cleaning component 96, the working process of the suction hopper 94 during use is improved. In the mounting bracket 92, the strip plate 962 on the outer surface of the bottom fixed shaft 961 can drive the cleaning soft brush plate 963 to come into contact with the outer surface of the cone-shaped filter screen 95. When the suction hopper 94 rotates with the rotary joint 93, the cleaning soft brush plate 963 can clean the impurities attached to the filter screen 95. This design not only ensures the accuracy and synchronization of the angle adjustment of the suction hopper 94 through the cooperation of the transmission mechanism 97 and the transmission component 973, and improves the targeting of flue gas collection, but also realizes the real-time cleaning of the filter screen 95 with the help of the cleaning component 96, avoiding impurities clogging the filter screen and affecting the flue gas filtration effect, maintaining the stable operation of the suction module 9, and further optimizing the equipment's ability to handle cutting flue gas.

[0020] Please refer to Figures 1-4Anti-slip strips 10 are fixedly connected at equal intervals along the arrangement direction of the conveyor belt 3 on its outer surface. The corners of the outer surface of the base frame 1 are all rounded. During the application of this device, by setting anti-slip strips 10 at equal intervals along the arrangement direction on the outer surface of the conveyor belt 3, the friction between the steel plate and the surface of the conveyor belt 3 can be increased during the conveying of the steel plate. This prevents the steel plate from sliding or shifting due to the operation of the conveyor belt 3 or its own weight, ensuring that the steel plate is stably conveyed to the designated cutting position and reducing the cutting deviation caused by the displacement of the steel plate. At the same time, by setting the corners of the outer surface of the base frame 1 to be rounded, the operators can avoid being hit by sharp corners when working or moving around the equipment, thus improving the safety of the equipment during use.

[0021] Please refer to Figures 1-7The laser cutting mechanism 8 includes an inner frame 81, which is fixedly installed at the bottom of the slider 65. An electric push rod 82 is fixedly installed on the inner side of the inner frame 81. The output end of the electric push rod 82 passes through the inner frame 81 and is fixedly installed with a laser cutting head 83. The purification module 7 includes a mounting plate 71, which is fixedly installed on the top of the top rail frame 61 at the end away from the drive motor 63. A suction fan 72 is fixedly installed on the top of the mounting plate 71. An activated carbon purification box 73 is fixedly installed at the input end of the suction fan 72. The input end of the suction fan 72 and the output end of the activated carbon purification box 73 are connected. An activated carbon purification core is fixedly installed inside the purification box 73. A maintenance sealing cover 74 is bolted to one side of the activated carbon purification core. A connecting pipe 75 is fixedly installed at the front end of the activated carbon purification box 73. Negative pressure suction hoses 76 are fixedly installed at both output ends of the connecting pipe 75. The input end of the negative pressure suction hoses 76 is connected to the output end of the rotary joint 93 at the top of the suction duct 94. A purified flue gas exhaust pipe 77 is fixedly installed at the output end of the suction fan 72. An external flue gas treatment equipment pipe connection flange 78 is fixedly installed at the output end of the purified flue gas exhaust pipe 77. During the application of this device, its... By setting up a laser cutting mechanism 8 and a purification module 7, the laser cutting mechanism 8 can use the electric push rod 82 inside the inner frame 81 to push the laser cutting head 83 to adjust the distance between it and the steel plate, meeting the cutting needs of steel plates of different thicknesses and ensuring that the laser cutting head 83 can accurately emit laser to complete the cutting operation. At the same time, the purification module 7 can generate negative pressure through the suction fan 72 on the top of the mounting plate 71. The negative pressure is transmitted to the suction hopper 94 through the activated carbon purification box 73, the connecting pipe 75, and the negative pressure suction hose 76, drawing the fumes generated during cutting into the purification module 7. The fumes first pass through the activated carbon purification box 73. The activated carbon purification core adsorbs harmful components, and the purified flue gas is then discharged through the purified flue gas exhaust pipe 77 at the output end of the exhaust fan 72. If further treatment of the flue gas is required, it can be connected to external equipment through the external flue gas treatment equipment pipeline connection flange 78 at the output end of the purified flue gas exhaust pipe 77. In addition, the maintenance sealing cover 74 on one side of the activated carbon purification box 73 is installed with bolts, which facilitates the later opening and replacement of the activated carbon purification core, ensuring the long-term stable purification effect of the purification module 7. The overall design not only realizes the flexible and precise cutting of the steel plate, but also efficiently treats the cutting flue gas, reducing the impact of harmful flue gas on the environment.

[0022] Please refer to Figures 1-5The displacement module 6 includes a top rail frame 61 and a fixed frame 62. The top rail frame 61 is fixedly installed on the top of the mounting frame 5, and the fixed frame 62 is fixedly installed on the upper side of one side of the mounting frame 5. A drive motor 63 is fixedly installed on the top of the fixed frame 62. A lead screw 64 is rotatably connected inside the top rail frame 61. The output end of the drive motor 63 is connected to the end of the lead screw 64 through a coupling. A slider 65 is threadedly connected to the outer surface of the top rail frame 61. The slider 65 is slidably connected inside the top rail frame 61. Side frames 91 are fixedly installed on both sides of the slider 65. A laser cutting mechanism 8 is fixedly installed on the bottom of the slider 65. A support frame 98 is fixedly installed in the middle of the side of the mounting frame 92 near the slider 65. The outer side of the support frame 98 is fixedly connected to the bottom of the slider 65. During the application of this device, by setting the displacement module 6 and the support frame 98, the drive motor 63 on the top of the fixed frame 62 can drive the internal components of the top rail frame 61 through the coupling. When the lead screw 64 rotates, it drives the threaded slider 65 to slide along the top rail frame 61, thereby adjusting the lateral position of the laser cutting mechanism 8 at the bottom of the slider 65 to meet the cutting needs of different areas of the steel plate. At the same time, the side frames 91 on both sides of the slider 65 can also move synchronously with the slider 65 to ensure that the position of the suction module 9 and the laser cutting mechanism 8 is adapted. In addition, the support frame 98 on one side of the mounting frame 92 can strengthen the connection between the mounting frame 92 and the bottom of the slider 65, preventing the mounting frame 92 from shaking when it moves with the slider 65 or when the suction module 9 is working, thus ensuring the stable operation of the suction module 9. The overall design realizes the flexible displacement of the laser cutting mechanism 8 through the displacement module 6, improving the coverage and accuracy of the cutting operation. Combined with the reinforcement of the support frame 98, it further enhances the stability of the operation of each component of the equipment, reduces the operation deviation caused by loose components, and ensures the overall processing effect and service life of the equipment.

[0023] The implementation principle of a laser cutting machine for steel plate processing according to an embodiment of this application is as follows: During application, after the device is started, it first enters the steel plate conveying stage. The base frame 1 serves as the overall support structure, providing a stable mounting foundation for all components of the equipment. The conveyor frame 2 provides a mounting carrier for the conveyor belt 3. The anti-slip strips 10 on the outer surface of the conveyor belt 3 increase the friction between the steel plate and the conveyor belt 3, preventing the steel plate from slipping during conveying. The corners of the outer surface of the base frame 1 are rounded to reduce the risk of collision injury to the operator. By setting the base plate 4, a stable support surface can be provided for subsequent steel plate cutting during use. The steel plate to be cut moves with the conveyor belt 3 to the top of the base plate 4. After that, the next stage can be entered, which is the cutting position adjustment stage. The mounting frame 5 provides an installation carrier for the displacement module 6. After the drive motor 63 on the top of the fixed frame 62 is started, it can drive the lead screw 64 to rotate through the coupling. Since the slider 65 is threadedly connected to the lead screw 64 and slidably connected inside the top rail frame 61, the rotation of the lead screw 64 will drive the slider 65 to move laterally along the top rail frame 61. The laser cutting mechanism 8 is fixedly connected to the slider 65 and can move synchronously with the slider 65 to realize the lateral adjustment of the cutting position. The side frame 91 provides a fixed foundation for the mounting frame 92 of the suction module 9. The support frame 98 can enhance the stability of the connection between the mounting frame 92 and the slider 65. After the steel plate is placed on top of conveyor belt 3, the laser cutting and flue gas collection synchronization stage can begin. The internal frame 81 provides installation space for the electric push rod 82. Once the electric push rod 82 is activated, its output end can push the laser cutting head 83 up and down, adjusting the distance between the laser cutting head 83 and the steel plate to meet the cutting needs of steel plates of different thicknesses. After the laser cutting head 83 is activated, it emits a high-power-density laser beam to cut the steel plate. Simultaneously with the laser cutting head 83's operation, the purification module 7 is activated. The mounting plate 71 provides installation support for the suction fan 72. After the suction fan 72 is activated, it uses activated carbon to remove smoke. The carbon purification box 73, connecting pipe 75, and negative pressure suction hose 76 form a negative pressure environment. By setting suction hoppers 94 that are inclined on both sides of the laser cutting mechanism 8, the suction can be accurately aimed at the area where the laser cutting generates smoke during use. Under the action of negative pressure, the smoke is sucked into the suction hopper 94. The cone-shaped filter screen 95 inside the suction hopper 94 can first filter large particulate impurities in the smoke, preventing large particulate impurities from directly entering the subsequent purification structure. Moreover, the cone-shaped setting of the filter screen 95 can further increase its filtration area, thereby further improving its overall filtration efficiency. During the lateral movement of the laser cutting mechanism 8 with the slider 65, the suction hopper 94 adjusts and the filter 95 cleans simultaneously. The side frame 91 drives the mounting frame 92 to move synchronously with the slider 65, and the transmission mechanism 97 operates accordingly. The fixed plate 972 provides mounting support for the shaft 974. When the shaft 974 moves with the mounting frame 92, the spur gear 976 meshes with the rack 9733. The spur gear 976 can roll along the rack 9733 as the slider 65 moves, thereby driving the shaft 974 and the bevel gear 975 to rotate. The bevel gear 975 meshes with the bevel ring 971, which can drive the bevel ring 971 and the rotary joint 93 to rotate. The suction hopper 94 is fixedly connected to the rotary joint 93 and can rotate synchronously with the rotary joint 93, and follows the laser cutting process during laser cutting. The cutting head 83 shifts laterally, always keeping the opening of the suction hopper 94 facing the area where the laser cutting generates smoke. The rotary joint 93 is connected to the negative pressure suction hose 76, ensuring that the smoke delivery channel is unobstructed when the suction hopper 94 rotates. By setting a cleaning soft brush plate 963, and the cleaning soft brush plate 963 is attached to the outer surface of the filter screen 95, during use, when the suction hopper 94 rotates with the rotary joint 93, the cleaning soft brush is in a fixed state, while the filter screen 95 and the cleaning soft brush plate 963 move relative to each other. The cleaning soft brush plate 963 can brush away the impurities attached to the filter screen 95, and its rotation can maintain the cleaning effect. The fixed shaft 961 provides an installation base for the strip plate 962, and the strip plate 962 provides fixed support for the cleaning soft brush plate 963. Finally, the flue gas enters the purification and emission stage. The flue gas, initially filtered by filter screen 95, sequentially passes through rotary joint 93, negative pressure suction hose 76, and connecting pipe 75 into activated carbon purification box 73. The activated carbon purification core adsorbs and purifies the harmful gases in the flue gas. A maintenance sealing cover 74, bolted to one side of the activated carbon purification box 73, facilitates easy disassembly and replacement of the activated carbon purification core during use. The purified flue gas enters the suction fan 72 and is then discharged through the purified flue gas exhaust pipe 77. An external flue gas treatment equipment connection flange 78 can connect to external flue gas treatment equipment for further treatment, ensuring emissions meet standards. This technical solution utilizes the lead screw 64 transmission design of displacement module 6 to achieve precise position adjustment of the laser cutting mechanism 8. Combined with the reinforcement of support frame 98, this enhances the overall structural stability of the equipment. Laser cutting and flue gas collection are performed simultaneously, and the inclined suction hopper 94 and conical filter screen 95 effectively control the flue gas... The timely capture and initial filtration effectively reduce the impact of large particulate impurities on subsequent purification structures, improving the initial effect of flue gas treatment. The transmission mechanism 97 enables the suction hopper 94 to move and rotate synchronously with the laser cutting head 83, completely solving the problem of flue gas leakage and escape caused by the inability of the suction structure to move with the laser in traditional equipment. Simultaneously, the real-time cleaning design of the cleaning component 96 prevents the filter screen 95 from clogging due to impurities, ensuring unobstructed flue gas transport channels and maintaining stable smoke treatment efficiency. The combination of the activated carbon purification core and the external flue gas treatment equipment significantly optimizes the flue gas purification effect, meeting environmental emission requirements. The design of the maintenance sealing cover 74 reduces the difficulty and cost of later equipment maintenance. The coordinated operation of the entire device at each stage, such as the anti-slip strip 10 ensuring stable steel plate transport and the electric push rod 82 adapting to cutting steel plates of different thicknesses, further enhances the overall practicality and operational safety of the equipment, meeting the diverse needs of steel plate processing in industrial production.

[0024] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
