Description

Technical Field

[0001] This utility model relates to the field of beveling equipment technology, specifically to a beveling cutting smoke exhaust system and a beveling cutting robot. Technical Background

[0002] Beveling is an essential step before welding workpieces to ensure a tight weld. Existing beveling equipment uses a truss and beveling machine head to perform beveling. The truss typically uses a top rail structure, where the rail is above the ground and supported by a support frame. Top rails require high-strength materials to prevent breakage during use. Furthermore, the top rail configuration can affect and interfere with the movement of the beveling machine head as the truss moves it.

[0003] To address the aforementioned issues, Chinese Utility Model Patent Application No. 202020246116.4 discloses a beveling robot, characterized by: a worktable, a moving device, and a beveling machine head. The workpiece is located on the worktable, which is situated on the ground. The moving device is positioned close to the worktable, and the beveling machine head is mounted on the moving device, directly above and close to the worktable. The moving device includes a ground rail, a support rod, a transverse rod, and a longitudinal rod, with the ground rail positioned on the ground. The robot beveling is performed by the moving device driving the beveling machine head, but the ground rail provides a fixed support, reducing rigidity requirements and ensuring greater stability during the movement of the beveling machine head. Furthermore, the ground rail does not interfere with the movement of the beveling machine head.

[0004] However, the above-mentioned existing technology has the following technical problems: during the beveling process, a large amount of smoke and dust is generated. This smoke and dust has a strong irritating odor and contains toxic substances. After being absorbed by the human body, it will seriously endanger the health of the operators and pollute the environment. The smoke and dust will also contaminate the cutting head and reduce the stability and cutting performance of the laser. Utility Model Content

[0012] The workbench is set on the ground, and the moving device is positioned close to the workbench. The beveling machine head is mounted on the moving device, which drives the beveling machine head to move, thereby beveling the workpiece on the workbench. The moving device includes a ground rail, a support rod, a transverse rod, and a longitudinal plate. The ground rail is set on the ground and close to the workbench.

Detailed Implementation

[0031] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0032] Please refer to Figures 1 to 11 This utility model provides a bevel cutting smoke exhaust system 20, including a smoke and dust extraction pipe 21, a partition opening and closing mechanism 22, and a smoke and dust extraction and processing component 23;

[0033] The dust extraction pipe 21 is fixedly installed below the bevel cutting workbench 11, with one end closed and the other end connected to the dust extraction and treatment component 23. The dust extraction pipe 21 is provided with at least one dust extraction zone, and each extraction zone is provided with a dust extraction port 211 to extract and treat the dust generated during cutting through the dust extraction and treatment component 23. The partition opening and closing mechanism 22 is fixedly installed on the dust extraction port 211 to control the opening or closing of the dust extraction port 211 to extract cutting dust from different locations.

[0034] In this embodiment, the bevel cutting fume extraction system 20 is particularly suitable for bevel cutting operations on sheet metal, especially in industrial environments requiring efficient handling of cutting fumes. For example, in shipbuilding, steel structure processing, pressure vessel manufacturing, and heavy machinery manufacturing, a large amount of fumes and harmful gases are generated during bevel cutting. Traditional fume extraction systems often fail to meet the requirements for efficient and precise fume extraction. This application, however, divides the fume extraction pipe 21 into at least one fume extraction zone and sets a zone opening and closing mechanism 22 on the fume extraction port 211 to discharge cutting fumes from different zones. It also adds a water curtain treatment mechanism 231 to absorb and settle the fumes generated during cutting. This not only improves the fume extraction efficiency and reduces fume extraction energy consumption but also reduces the impact of fumes on the cutting environment and worker health.

[0035] Furthermore, the partition opening and closing mechanism 22 includes multiple dust baffles 221, connecting rods 222, rotating rods 223, and a drive module 224. The multiple dust baffles 221 are rotatably installed on one side of the dust suction port 211. Each dust baffle 221 is provided with a rotating arm and is rotatably connected to the connecting rods 222. One end of the rotating rod 223 is rotatably connected to the connecting rods 222, and the other end is rotatably connected to the drive shaft of the drive module 224, so that the dust baffles 221 can be controlled by the drive module 224 to open or close the dust suction port 211.

[0036] In this embodiment, the drive module 224 is a push rod motor, which has a simple structure and is easy to install. The dust baffle 221 can be made of high temperature and corrosion resistant materials (such as stainless steel or special alloys) to adapt to high temperature dust and harsh working environment.

[0037] In another implementation, the drive module 224 can employ a servo motor or a stepper motor to achieve more precise control and faster response. Servo motors and stepper motors can precisely adjust the opening and closing angle of the smoke baffle 221 according to the real-time situation of smoke generation through the control system, thereby optimizing the smoke extraction effect. This is particularly suitable for working conditions with large variations in smoke concentration or complex cutting paths, enabling dynamic adjustment of suction force to further improve smoke extraction efficiency and reduce energy consumption.

[0038] Of course, the zone opening and closing mechanism 22 can also integrate sensor modules and control modules (such as dust concentration sensors, position sensors, etc.) for real-time monitoring of dust distribution and cutting position. The sensor modules feed data back to the control module, which automatically adjusts the operating state of the drive module 224 based on the feedback information to achieve intelligent and adaptive dust extraction. For example, when the sensor detects a high dust concentration in a certain area, the control module will immediately adjust the opening angle of the corresponding dust baffle 221 to increase the suction force in that area and ensure that the dust is quickly removed.

[0039] Furthermore, the smoke and dust extraction and treatment component 23 includes a water curtain treatment mechanism 231 and a smoke and dust extraction module 232. The water curtain treatment mechanism 231 is fixedly installed on one side of the bevel cutting workbench 11, with one end connected to the smoke and dust extraction pipe 21 and the other end connected to the smoke and dust extraction module 232, so as to form a barrier through the water curtain, adsorb and settle the passing smoke and dust. The smoke and dust extraction module 232 is mainly used to extract the smoke and dust generated by cutting into the water curtain treatment mechanism 231 and discharge the treated gas.

[0040] In this embodiment, the water curtain treatment mechanism 231 effectively adsorbs and settles passing smoke and dust by forming a uniform water barrier, especially showing significant effects on the treatment of fine particles and harmful substances. The smoke and dust extraction module 232 includes a filter and an exhaust fan for further purifying the gas and discharging it outdoors. The filter can capture fine particles that the water curtain treatment mechanism 231 fails to completely process, ensuring that the emitted gas meets environmental protection standards.

[0041] Furthermore, the water curtain treatment mechanism 231 includes a smoke collection box 2311, a water curtain plate 2312, a circulating water pump 2313, and a filter tank 2314. The smoke collection box 2311 is fixedly installed on one side of the bevel cutting workbench 11 and is provided with a smoke inlet 23111 and an air outlet 23112. The smoke inlet 23111 is connected to the smoke extraction pipe 21 to introduce cutting fumes into the smoke collection box 2311. The air outlet 23112 is connected to the smoke extraction module 232 to discharge purified gas. The water curtain plate 2312 is fixedly installed in the smoke collection box 2311 and is provided with... There is a water tank 23121, and a row of equally spaced water outlet holes 23122 are provided at the bottom of the water tank 23121 to allow water in the water tank 23121 to flow out and form a water curtain on the water curtain plate 2312. The circulating water pump 2313 is fixedly installed on the outside of the smoke collection box 2311. Its water inlet 23131 is located at the bottom of the smoke collection box 2311, and its water outlet 23132 is located in the water tank 23121 on the water curtain plate 2312 to realize the recycling of water. A filter tank 2314 is also provided at the water inlet 23131 of the circulating water pump 2313 to prevent the circulating water pump 2313 from being blocked.

[0042] In this embodiment, the smoke and dust enter the smoke collection box 2311 through the smoke and dust extraction pipe 21. Inside the smoke collection box 2311, the smoke and dust particles come into contact with the water curtain formed by the water curtain plate 2312. The smoke and dust particles are attached to the water and settle to the bottom of the smoke collection box 2311 with the water flow. The purified gas enters the smoke and dust extraction module 232 through the air outlet 23112, is further processed and discharged. The settled water is extracted by the circulating water pump 2313, filtered through the filter tank 2314 and then transported back to the water tank 23121 of the water curtain plate 2312 to form a water curtain circulation. The smoke collection box 2311 and the water curtain plate 2312 are made of corrosion-resistant materials (such as stainless steel or engineering plastics) to adapt to high temperature, high humidity and corrosive smoke and dust environments.

[0043] It is worth noting that the filter tank 2314 typically uses multi-layer filter screens or filter cartridges, which can effectively capture solid particles in the water, ensure the cleanliness of the circulating water, and prevent the circulating water pump 2313 from becoming clogged.

[0044] In another embodiment, a high-pressure water pump and atomizing nozzles can be installed in the water tank 23121 on the water curtain plate 2312 to spray water in the form of fine water mist, forming a uniform water mist barrier. When the smoke and dust pass through the water mist barrier, the water mist will collide and adsorb with the smoke and dust particles, causing the smoke and dust particles to be wrapped by the water mist and increase in weight, thereby settling into the water tank 23121. Compared with the water curtain, the adsorption and sedimentation effect is better.

[0045] In addition, flow sensors and pressure sensors can be integrated into the circulating water pump 2313 to monitor the water flow status in real time, and the operating parameters of the water pump can be adjusted through the control system to optimize the water curtain effect and reduce energy consumption.

[0046] This utility model also provides a beveling robot 10, including a workbench 11, a moving device 12, a beveling machine head 13, and the aforementioned beveling smoke exhaust system 20;

[0047] The workbench 11 is set on the ground, and the moving device 12 is positioned close to the workbench 11. The beveling machine head 13 is mounted on the moving device 12, so that the moving device 12 drives the beveling machine head 13 to move, thereby beveling the workpiece on the workbench 11. The moving device 12 includes a ground rail 121, a support rod 122, a transverse rod 123, and a longitudinal plate 124. The ground rail 121 is set on the ground and positioned close to the workbench 11. One end of the support rod 122 is slidably connected to the ground rail 121 to allow the support to move. The support rod 122 can move along the length of the ground rail 121. The other end of the support rod 122 is connected to the transverse rod 123 so that the transverse rod 123 can be moved by the support rod 122. The longitudinal plate 124 is connected to the transverse rod 123 so that the longitudinal plate 124 can move along the length of the transverse rod 123. The beveling machine head 13 is set on the longitudinal plate 124 and can move in the vertical direction. The beveling cutting smoke exhaust system 20 is installed below the workbench 11 to extract and treat the smoke generated during cutting.

[0048] In this embodiment, the workpiece is beveled by moving the beveling machine head 13 through the moving device 12. However, the track is set as a ground track 121. The ground track 121 is set on the ground and its rigidity requirement is not high. The ground provides a certain fixed support for the ground track 121, which can ensure that the movement of the beveling machine head 13 is more stable. Furthermore, the setting of the ground track 121 will not affect or interfere with the movement of the beveling machine head 13.

[0049] Furthermore, there are two ground rails 121, located on opposite sides of the workbench 11, and two support rods 122, connected to the two ground rails 121 respectively. The ground rails 121 are perpendicular to the support rods 122, the support rods 122 are perpendicular to the transverse rods 123, and the transverse rods 123 are perpendicular to the longitudinal plate 124.

[0050] Furthermore, the ground rail 121 is provided with a first rack 1211 along its length direction, and a first gear 1221 is provided at one end of the support rod 122. The first gear 1221 meshes with the first rack 1211 so that by rotating the first gear 1221, the first gear 1221 moves along the direction of the first rack 1211, thereby enabling the support rod 122 to move along the length direction of the ground rail 121, and thus enabling the support rod 122 to drive the transverse rod 123 to move along the length direction of the ground rail 121.

[0051] Furthermore, a connecting plate 1233 is provided between the transverse rod 123 and the longitudinal plate 124. The transverse rod 123 is provided with a second rack 1231 along its length direction. A second gear 1232 is provided on the connecting plate 1233. The second gear 1232 meshes with the second rack 1231, so that rotating the second gear 1232 causes the second gear 1232 to move along the direction of the second rack 1231, thereby driving the longitudinal plate 124 to move along the length direction of the transverse rod 123. The longitudinal plate 124 is provided with a guide rail 1241 and a lead screw 1242 along the vertical direction. The beveling machine head 13 is movably mounted on the guide rail 1241 and threadedly connected to the lead screw 1242, so that rotating the lead screw 1242 causes the beveling machine head 13 to move along the vertical direction.

[0052] Furthermore, the mobile device 12 also includes a first driver 125, a second driver 126, and a third driver 127. There are two first drivers 125, which are respectively connected to the first gears 1221 provided on the two support rods 122 to provide power to the first gears 1221. The driving end of the second driver 126 is connected to the second gear 1232 to provide power to the second gear 1232. The driving end of the third driver 127 is connected to the lead screw 1242 to provide power to the lead screw 1242.

[0053] Furthermore, the beveling machine head 13 includes a fourth driver 131, a first rotating rod 132, a fifth driver 133, a second rotating rod 134, a cutting torch 135, and a beveling machine head mounting plate 136. The beveling machine head mounting plate 136 is provided with a guide groove, which cooperates with the guide rail 1241 provided on the longitudinal moving plate 124 and is threadedly connected to the lead screw 1242, so as to drive the beveling machine head mounting plate 136 to move along the guide rail 1241 through the lead screw 1242. The fourth driver 131 is provided on the beveling machine head 13 mounting plate. The driving end of the fourth driver 131 is connected to one end of the first rotating rod 132 to drive the first rotating rod 132 to rotate. The other end of the first rotating rod 132 is connected to the fifth driver 133. The driving end of the fifth driver 133 is connected to one end of the second rotating rod 134 to drive the second rotating rod 134 to rotate. The other end of the second rotating rod 134 is connected to the cutting torch 135.

[0054] In this embodiment, the workbench 11 is a cuboid, the length of the ground rail 121 is greater than the length of the workbench 11, and the length of the ground rail 121 can be adjusted according to the length of the workbench 11; the ground rail 121 can be extended or shortened as needed, unlike the top rail which is not restricted, and the ground rail 121 can also appropriately reduce the cross-sectional area compared to the top rail, saving materials.

[0055] Of course, the first driver 125, the second driver 126, the third driver 127, the fourth driver 131, and the fifth driver 133 are all servo motors, enabling more precise control and faster response speed.

[0056] Before implementing this utility model, water needs to be poured into the smoke collection box 2311 until the water level is close to the water curtain plate 2312. Then, the circulating water pump 2313 is started to transport the water in the smoke collection box 2311 to the water tank 23121 above the water curtain plate 2312, and the water flows out through the pre-set water outlet 23122 below the water tank 23121, thereby forming a stable water curtain barrier on the water curtain. When smoke is required during beveling, the corresponding drive module 224 is activated to open the smoke extraction port 211. Then, the smoke extraction module 232 is activated, and the smoke enters the smoke collection box 2311 through the smoke extraction pipe 21. Inside the smoke collection box 2311, the smoke comes into contact with the water curtain formed by the water curtain plate 2312. The smoke particles are attached by the water and settle to the bottom of the smoke collection box 2311 with the water flow. The purified gas enters the smoke extraction module 232 through the air outlet 23112 for further processing before being discharged. This not only improves the smoke extraction efficiency and reduces the smoke extraction energy consumption, but also reduces the impact of smoke on the cutting environment and the health of workers.

[0057] The modules or units in the device of this utility model embodiment can be merged, divided, and deleted according to actual needs. The above-disclosed embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of this utility model. Those skilled in the art can understand that implementing all or part of the processes of the above embodiments and making equivalent changes according to the claims of this utility model still fall within the scope of this utility model.
