Description

Technical Field

[0001] This invention relates to the field of iron oxide removal devices, and more particularly to a rolling-cutting double-sided shearing iron oxide removal device. Background Technology

[0002] In heavy plate mills, the temperature straightening machine is located after the cooling bed. Thin steel plates pass through the cooling bed at a lower straightening temperature, resulting in severe breakage of the brittle iron oxide scale after straightening. During the double-sided shearing process, the vibration generated by the blades causes a large amount of broken iron oxide scale to fall onto the shearing machine platform, adhering to the surfaces of the pinch rollers and pressure feet. This causes localized bulges on the pinch rollers and pressure feet, directly creating corresponding indentations on the steel plate surface. Furthermore, as the steel plate passes through the shearing machine's leveling track, a significant amount of iron oxide scale adheres to its lower surface, further contributing to defects as it is pressed into the steel plate surface by the pinch rollers and pressure feet.

[0003] Traditional devices only have rubber pad scrapers for the pinch rollers, which can only clean the iron oxide scale on the surface of the pinch rollers. However, if the amount of iron oxide scale on the steel plate is too large, it will adhere to the surface of the pinch rollers, causing indentations on the steel plate when the pinch rollers are conveying the steel plate. In addition, the traditional shearing device blows air continuously through the air pipe during use, which may cause iron oxide scale to be blown into the eyes of the staff when they go to check the machine.

[0004] In view of this, this paper studies and improves the existing problems, and provides a rolling-cutting double-sided shearing iron oxide scale removal device. The device has a reasonable structural design, high stability, and can be used in various aspects. The aim is to solve the problems and improve the practical value through this technology. Summary of the Invention

[0005] This invention removes iron oxide scale from the surface of a steel plate by blowing air at both ends of the plate as it enters the machine. This prevents iron oxide scale from adhering to the surfaces of the first conveyor roller and the pressure foot during the conveying process, which could cause localized protrusions on the surfaces of the first conveyor roller and the pressure foot, resulting in indentations on the steel plate surface. Simultaneously, a valve controls the main conveying pipe, allowing the equipment to start air intake for blowing during operation and gradually stop air intake when the valve is closed. This facilitates easy inspection by personnel, thus realizing a double-sided shearing iron oxide scale removal device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a double-sided shearing iron oxide scale removal device with a rolling cutter, comprising a base, an outer cover for protection fixedly connected to the upper end of the base, a motor for driving fixedly connected to one side of the outer cover, a first conveying roller arranged inside the outer cover, a connecting shaft fixedly connected to both ends of the first conveying roller, a first cleaning blowpipe fixedly connected to the side of the first conveying roller near the outer end, a nozzle fixedly connected to the side of the first blowpipe near the inner end, a connecting pipe for transmission fixedly connected to the upper end of the first blowpipe, two sets of second blowpipes fixedly connected to both sides of the first conveying roller, a pulley A fixedly connected to the outer side of the connecting shaft, a pulley B arranged on one side of the pulley A, a belt for transmission arranged inside the pulley A, a cutting blade fixedly connected to the side of the pulley B near the inner end, and a wear-resistant platform fixedly connected to the center of the inner side of the outer cover.

[0007] Preferably, the outer cover is installed and fixed by the base, and the lower end of the outer cover is hollow. Several sets of motors are fixedly connected to one side of the outer cover. The drive end of each set of motors is connected to the connecting shaft at one end of the first conveying roller. The first conveying roller is connected to the inner wall of the outer cover through the connecting shafts at both ends. Two sets of the first blowing pipes are fixedly connected to one end of the outer cover. Each set of first blowing pipes is equipped with several sets of nozzles, and each set of nozzles is inclined towards the center.

[0008] Preferably, the first purge pipe is connected to two sets of second purge pipes via a connecting pipe, and several sets of nozzles are connected to the outside of the second purge pipes. The nozzles on the outside of the two sets of second purge pipes are inclined downward and located between the first conveying rollers.

[0009] Preferably, the cutting blade is disposed at the gap between the two ends of the first conveying roller, and the cutting blade is disposed at both ends of the first conveying roller. The two sets of cutting blades are connected to each other. The pulley A and pulley B are connected by a belt. The wear-resistant platform is fixed by connecting its lower end to the inner side of the outer cover. The upper surface of the wear-resistant platform is flush with the center of the first conveying roller.

[0010] Preferably, a third purge pipe is provided on one side of the wear-resistant platform. The third purge pipe passes through the outer cover and is connected to the connecting pipe. A conveying main pipe is provided at the upper end of the third purge pipe. One end of the conveying main pipe is connected to the connecting pipe, and the other end is connected to the air intake device.

[0011] Preferably, a fourth purge pipe is connected to one side of the third purge pipe via a connecting pipe. Several sets of nozzles are fixedly connected to the outside of the fourth purge pipe, and each set of nozzles is slightly upward. A second conveying roller is provided at the upper end of the fourth purge pipe, and the second conveying roller is rotated by the drive of a motor.

[0012] Preferably, a set of connecting rods is connected to the upper inner side of the first conveying roller via a connecting shaft. The connecting rods extend through the outer cover to the outer end and are connected to a rack. A gear is provided on one side of the conveying main pipe. The gear is located at the upper end of the rack and meshes with the rack. A spring rod is fixedly connected to the end of the gear near the conveying main pipe. The gear is connected to the conveying main pipe through the spring rod, and the spring rod extends through the conveying main pipe and is connected to the valve inside the conveying main pipe.

[0013] The present invention has the following beneficial effects: When the steel plate enters, air is blown at both ends of the steel plate to remove the iron oxide scale on the surface of the steel plate, preventing it from adhering to the surface of the first conveyor roller and the pressure foot during the first conveyor roller's conveying process, which would cause local bulging of the first conveyor roller and the pressure foot surface, resulting in indentations on the surface of the steel plate. At the same time, the vibration generated by the cutting blade causes a large amount of broken iron oxide scale to fall into the shearing machine platform. At this time, the second blowing pipe will blow the generated iron oxide scale downwards. While blowing air, air is also blown on the outer surface of the first conveyor roller to clean the outer surface of the first conveyor roller. When the equipment is shut down, the rotation of the rack will stop, and the spring rod will gradually close the valve inside the conveying main pipe, stopping the air intake into the connecting pipe. This prevents iron scale from flying and injuring the workers when they go to check after cutting a set of steel plates. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Reference Figure 1-5 An embodiment of the present invention provides a double-sided shearing iron oxide scale removal device for rolling cutting, comprising a base 1, an outer cover 2 for protection fixedly connected to the upper end of the base 1, a motor 3 for driving fixedly connected to one side of the outer cover 2, a first conveying roller 4 arranged inside the outer cover 2, a connecting shaft 5 fixedly connected to both ends of the first conveying roller 4, a first cleaning blowing pipe 6 fixedly connected to the side of the first conveying roller 4 near the outer end, a nozzle 7 fixedly connected to the side of the first blowing pipe 6 near the inner end, a connecting pipe 8 for transmission fixedly connected to the upper end of the first blowing pipe 6, two sets of second blowing pipes 9 fixedly connected to both sides of the first conveying roller 4, a pulley A10 fixedly connected to the outer side of the connecting shaft 5, a pulley B11 arranged on one side of the pulley A10, a belt 12 for transmission arranged inside the pulley A10, a cutting blade 13 fixedly connected to the side of the pulley B11 near the inner end, and a wear-resistant platform 14 fixedly connected to the center of the inner side of the outer cover 2.

[0024] In an optional embodiment: the outer cover 2 is installed and fixed by the base 1. The lower end of the outer cover 2 is hollow, which facilitates the dropping of the iron scale generated during cutting to the lower end, preventing it from accumulating inside and causing difficulty in cleaning. It also facilitates subsequent cleaning. Several sets of motors 3 are fixedly connected to one side of the outer cover 2. The drive end of each set of motors 3 is connected to the connecting shaft 5 at one end of the first conveying roller 4. The first conveying roller 4 is connected to the inner wall of the outer cover 2 through the connecting shafts 5 at both ends. Two sets of first blowing pipes 6 are fixedly connected to one end of the outer cover 2. Each set of first blowing pipes 6 is equipped with several sets of nozzles 7, and each set of nozzles 7 is inclined towards the center. When the steel plate enters, it blows air at both ends of the steel plate to remove the iron oxide scale on the surface of the steel plate, preventing it from adhering to the surface of the first conveying roller 4 and the press foot during the first conveying roller 4 conveying process, causing local protrusion of the surface of the first conveying roller 4 and the press foot, thereby causing indentations on the surface of the steel plate.

[0025] In an optional embodiment: the first purge pipe 6 is connected to two sets of second purge pipes 9 by a connecting pipe 8. Several sets of nozzles 7 are connected to the outside of the second purge pipes 9. The nozzles 7 on the outside of the two sets of second purge pipes 9 are inclined downward and located between the first conveying rollers 4. When the steel plate is sheared on both sides, the vibration generated by the shearing blade 13 causes a large amount of broken iron oxide scale to fall into the shearing machine platform. At this time, the second purge pipe 9 will blow the generated iron oxide scale downward. While blowing air, it blows air onto the outer surface of the first conveying roller 4, thereby cleaning the outer surface of the first conveying roller 4.

[0026] In an optional embodiment: the cutting blades 13 are disposed at the gaps at both ends of the first conveying roller 4, with the cutting blades 13 disposed at both ends of the first conveying roller 4, and the two sets of cutting blades 13 are connected to each other. The pulleys A10 and B11 are connected by a belt 12. The wear-resistant platform 14 is fixed by connecting its lower end to the inner side of the outer cover 2, and its upper surface is flush with the center of the first conveying roller 4. The two sets of cutting blades 13 are movably connected to the inner wall of the outer cover 2. When the motor 3 drives the connecting shaft 5 to rotate the first conveying roller 4, the connecting shaft 5 will drive the pulley A10 to rotate synchronously. The pulley A10 will drive the pulley B11 to rotate synchronously through the belt 12. Since the pulley B11 is connected to the cutting blades 13, the rotation of the pulley B11 will drive the cutting blades 13 to rotate synchronously. Moreover, the outer diameter of the pulley A10 is larger than that of the pulley B11, so the rotation frequency of the pulley B11 is greater than that of the pulley A10. At the same time, the two sets of cutting blades 13 are connected to each other, thereby cutting during the conveying process.

[0027] In an optional embodiment: a third purge pipe 15 is provided on one side of the wear-resistant platform 14. The third purge pipe 15 passes through the outer cover 2 and is connected to the connecting pipe 8. A conveying main pipe 16 is provided at the upper end of the third purge pipe 15. One end of the conveying main pipe 16 is connected to the connecting pipe 8, and the other end is connected to the air intake device. The third purge pipe 15 blows away the iron scale generated by the steel plate when passing through the wear-resistant platform 14, thereby preventing excessive iron scale from accumulating on the surface of the wear-resistant platform 14 and causing indentations on the steel plate during subsequent transportation.

[0028] In an optional embodiment: a fourth blow pipe 17 is connected to one side of the third blow pipe 15 via a connecting pipe 8. Several sets of nozzles 7 are fixedly connected to the outside of the fourth blow pipe 17, and each set of nozzles 7 is slightly upward. A second conveying roller 18 is provided at the upper end of the fourth blow pipe 17. The second conveying roller 18 is rotated by the drive of the motor 3. Each set of nozzles 7 on the outside of the fourth blow pipe 17 is aligned with each set of second conveying rollers 18, so that when conveying the cut steel plate, the surface of the second conveying roller 18 is cleaned to prevent the long-term accumulation of iron oxide scale from causing defects on the surface of the steel plate.

[0029] In an optional embodiment: A set of connecting rods 19 near the upper inner side of the first conveying roller 4 is connected to a connecting shaft 5. The connecting rods 19 extend through the outer cover 2 to the outer end and are connected to a rack 20. A gear 21 is provided on one side of the conveying main pipe 16. The gear 21 is located above the rack 20 and meshes with the rack 20. A spring rod 22 is fixedly connected to one end of the gear 21 near the conveying main pipe 16. The gear 21 is connected to the conveying main pipe 16 through the spring rod 22, and the spring rod 22 extends through the conveying main pipe 16 and is connected to the valve inside the conveying main pipe 16. When the equipment is started, the motor 3 drives the first conveying roller 4 to rotate. The set of first conveying rollers 4 at the rear end will drive the rack 20 to rotate synchronously through the connecting rods 19. When the rack 20 rotates, it will continuously pass through the internal... The rack 20 drives the gear 21 to rotate. Since the gear 21 is connected to the valve inside the main conveying pipe 16 through the spring rod 22, the internal valve of the main conveying pipe 16 will open and allow air to enter when the rack 20 drives the gear 21 to rotate. Because the spring rod 22 has a certain tension, the spring rod 22 will drive the gear 21 to gradually spring back and reset when the gear 21 is rotated. At the same time as resetting, the internal valve of the main conveying pipe 16 will be closed. Thus, during the rotation of the rack 20, the internal valve of the main conveying pipe 16 will be continuously opened. When the equipment is shut down, the rotation of the rack 20 will stop, and the spring rod 22 will gradually close the internal valve of the main conveying pipe 16, stopping the air intake into the connecting pipe 8. This prevents the workers from being injured by flying iron sheets when they go to check after cutting a set of steel plates.

[0030] Working principle and process: The operator turns on the equipment and drives the first conveyor roller 4 to rotate via motor 3 to convey the steel plate. At the same time, the two sets of cutting blades 13 are driven to rotate synchronously through the transmission of pulley A10 to cut the steel plate. Before the steel plate enters the equipment, the two sets of first blowing pipes 6 blow air at the upper and lower ends of the steel plate. The second blowing pipe 9 blows air on the surface of the first conveyor roller 4 and the cutting area during the cutting and conveying process, thereby preventing the iron sheet from adhering to the surface of the first conveyor roller 4. At the same time, during the rotation of the first conveyor roller 4, the air intake of the conveying main pipe 16 is controlled by the rotation of the rack 20 driven by the connecting rod 19, thereby blowing air at the same time as cutting.
