Description

Technical Field

[0001] This application relates to the field of stainless steel pipe processing, and in particular to a system for spraying and wiping away colorants from stainless steel pipes. Background Technology

[0002] During the production of stainless steel pipes, cracks may appear on the surface of the pipes after they are formed. In order to improve the quality of the pipes, it is necessary to detect the cracks on the surface of the pipes and then process the cracked surfaces to remove the cracks. Usually, ultrasonic testing or manual testing is used to detect cracks. However, ultrasonic testing often misses some cracks.

[0003] During the inspection of cracks on the surface of steel pipes, a colorant is sprayed onto the pipe surface. The colorant penetrates into the cracks. The worker then holds a cloth against the surface of the pipe and wipes away the colorant. However, the colorant in the cracks is not easily removed by the cloth. Finally, a developer is sprayed onto the surface of the pipe, making it appear white, thus highlighting the colorant in the cracks. The developer is red, making it easier for the worker to observe the cracks on the surface of the pipe and to process the cracked areas.

[0004] Coloring agents are chemical reagents that are harmful to the body. When workers hold a rag against the outer wall of the steel pipe to remove the coloring agent, the coloring agent on the steel pipe can easily come into contact with the workers, thereby endangering their health and posing a certain degree of danger to the workers during the processing of stainless steel pipes. Summary of the Invention

[0005] To address the issue of colorants on steel pipes easily contaminating workers, this application provides a system for spraying and wiping away colorants from stainless steel pipes.

[0006] This application provides a colorant spraying and wiping system for stainless steel pipes, employing the following technical solution:

[0007] A colorant spraying and wiping system for stainless steel pipes includes a worktable, a rotating assembly, and a wiping assembly. The rotating assembly is connected to the worktable and drives the steel pipe to rotate along its own axis on the worktable. The wiping assembly includes a wiping seat and a wiping scraper. The wiping seat is slidably connected to the worktable, and the sliding direction of the wiping seat is parallel to the rotation axis of the steel pipe. The wiping scraper is slidably connected to the wiping seat, and the sliding direction of the wiping scraper is perpendicular to the sliding direction of the wiping seat. When the rotating assembly drives the steel pipe to rotate, the wiping scraper slides towards the steel pipe, and the scraping end of the wiping scraper presses against the outer wall of the steel pipe and scrapes off the colorant.

[0008] By adopting the above technical solution, the steel pipe after colorant spraying is placed on a rotating assembly. The rotating assembly drives the steel pipe to rotate along its own axis and connect to the worktable. The wiping scraper slides towards the steel pipe, and the scraping end of the scraping scraper presses against the outer wall of the steel pipe, so that the scraping end of the scraping scraper can press against the outer wall of steel pipes of different sizes. The outer wall of the steel pipe and the scraping end of the scraping scraper make rolling contact, and the scraping scraper scrapes off the colorant from the outer wall of the steel pipe. The wiping seat is slidably connected to the worktable, and the sliding direction of the wiping seat is parallel to the axis of the steel pipe. The wiping seat slides on the worktable, driving the scraping scraper to slide. The scraping scraper stably scrapes off the colorant from the outer wall of the steel pipe, realizing automatic cleaning of the colorant on the outer wall of the steel pipe. It eliminates the need for workers to hold a rag and press it against the outer wall of the steel pipe to wipe off the colorant, making it less likely for the colorant on the steel pipe to contaminate the workers, thereby protecting the health of the workers and improving the safety performance of the stainless steel pipe processing process.

[0009] Optionally, a spraying assembly is connected to the workbench. The spraying assembly is slidably connected to the workbench, and the sliding direction of the spraying assembly is parallel to the axis of the steel pipe. The spraying assembly is used to spray the colorant onto the outer wall of the steel pipe before the wiping assembly scrapes it off.

[0010] By adopting the above technical solution, during steel pipe processing, the rotating component drives the steel pipe to rotate around its own axis and connect to the worktable. First, the spraying component evenly sprays the colorant onto the outer wall of the steel pipe. Then, the scraping end of the wiping scraper slides towards the steel pipe, pressing against the outer wall of the steel pipe and scraping off the colorant. This achieves one-stop processing of steel pipe colorant spraying and cleaning, eliminating the need for workers to move the steel pipe from the spraying device to the cleaning device after the colorant spraying is completed. This reduces the workload of workers and improves the processing efficiency of stainless steel pipes.

[0011] Optionally, the wiping assembly further includes an air spray gun and a connecting seat. The connecting seat is connected to the wiping scraper, and the air spray gun is connected to the connecting seat. The air outlet of the air spray gun faces the steel pipe, and the air outlet of the air spray gun sprays airflow to impact the outer wall of the steel pipe and carry away the impurities on the outer wall of the steel pipe.

[0012] By adopting the above technical solution, before cleaning the colorant from the end face of the stainless steel pipe, the air outlet of the spray gun is directed towards the steel pipe on the workbench. The air jet from the spray gun impacts the outer wall of the steel pipe and carries away impurities from the outer wall, making it less likely for the impurities on the outer wall to wear down the scraping end of the scraper, thereby extending the service life of the scraper. At the same time, the air jet impacts the outer wall of the steel pipe, accelerating the speed between solvent molecules in the colorant, thereby accelerating the drying speed of the colorant on the outer wall of the steel pipe and improving the cleaning efficiency of the scraper on the outer wall of the steel pipe.

[0013] Optionally, the wiping assembly further includes a wiping cylinder. The wiping seat has a sliding groove for the wiping scraper to slide. The length direction of the sliding groove is parallel to the sliding direction of the wiping scraper. The wiping cylinder is connected to the wiping seat. The piston rod of the wiping cylinder passes through the wiping seat and is connected to the wiping scraper. The axis of the piston rod of the wiping cylinder is parallel to the sliding direction of the wiping scraper. The wiping cylinder drives the wiping scraper to slide on the inner wall of the sliding groove.

[0014] By adopting the above technical solution, when the steel pipe spraying is completed, the wiping cylinder drives the wiping scraper to slide towards the steel pipe, and the wiping scraper's pressing end presses against the outer wall of the steel pipe, so as to achieve precise positioning of the wiping scraper sliding on the inner wall of the chute.

[0015] Optionally, the wiping scraper includes a connecting part, an elastic part, and a wiping part. The connecting part is slidably connected to the inner wall of the groove. A compensation cavity is formed on the end face of the connecting part facing the worktable. One end of the elastic part in the elastic direction is connected to the inner wall of the compensation cavity, and the other end of the elastic part in the elastic direction is connected to the wiping part. The elastic part has the tendency to elastically drive the wiping part to slide towards the worktable. The end of the wiping part away from the elastic part is used to press against the outer wall of the steel pipe and scrape off the colorant.

[0016] By adopting the above technical solution, the connecting part slides towards the steel pipe from the inner wall of the groove, and the wiping end of the wiping part presses against the outer wall of the steel pipe. When the uneven outer wall of the steel pipe squeezes the wiping part, the steel pipe overcomes the elastic force of the elastic part and drives the wiping part to slide towards the connecting part. The friction between the steel pipe and the wiping part is reduced, making it less prone to wear between the wiping part and the steel pipe, thereby extending the service life of the wiping part and the processing quality of the steel pipe.

[0017] Optionally, the wiping scraper is connected to a connecting bolt, the connecting part has a connecting groove for the connecting bolt to pass through, and the wiping part has a sliding channel for the end of the connecting bolt to slide. The sliding channel communicates with the connecting groove. When the wiping part is slidably connected to the inner wall of the compensation cavity, the connecting bolt is slidably connected to the inner wall of the sliding channel.

[0018] By adopting the above technical solution, the end of the connecting bolt is provided with a connecting groove and embedded in the sliding channel. When the wiping end of the wiping part is pressed against the outer wall of the steel pipe, the steel pipe squeezes the wiping part and drives the wiping part to slide towards the connecting part, which drives the connecting bolt to slide and connect to the inner wall of the sliding channel. This makes it less likely for the wiping part to deviate when sliding on the inner wall of the sliding channel, thereby improving the stability of the wiping part sliding on the inner wall of the sliding channel.

[0019] Optionally, a cleaning scraper is connected to the connecting part, and a cleaning cavity is provided on the inner wall of the compensation cavity for the cleaning scraper to slide. The sliding direction of the cleaning scraper is parallel to the sliding direction of the wiping part, and the cleaning scraper presses against the wiping part and scrapes off the colorant.

[0020] By adopting the above technical solution, when the wiping end of the wiping part presses against the outer wall of the steel pipe and scrapes off the colorant, some of the colorant adheres to the wiping part. The cleaning scraper slides towards the connection part, presses against the wiping part and scrapes off the colorant adhering to the wiping part, thereby cleaning the wiping part and enabling the wiping part to stably scrape off the colorant on the steel pipe.

[0021] Optionally, a drive assembly is connected between the cleaning scraper and the connecting part. The drive assembly includes a drive block, a drive rod, and a drive elastic element. One end of the drive rod is connected to the cleaning scraper, and the other end of the drive rod passes through the connecting part and is connected to the drive block. The side of the drive block away from the drive rod is used to abut against the wiping seat. One end of the drive elastic element in the elastic direction is connected to the drive block, and the other end of the drive elastic element in the elastic direction is connected to the connecting part. The drive elastic element has the elasticity to drive the cleaning scraper to slide towards the connecting part, and the drive block protrudes from the connecting part.

[0022] By adopting the above technical solution, when the wiping part finishes cleaning the outer wall of the steel pipe, the wiping part slides away from the steel pipe along the inner wall of the chute. The driving block abuts against the top of the wiping seat and drives the driving rod to slide towards the cleaning chamber. The cleaning scraper presses against the wiping part and scrapes off the colorant on the wiping part, realizing the automatic cleaning of the colorant adhering to the wiping part. There is no need for the staff to manually drive the cleaning scraper to slide, reducing the workload of the staff and improving the processing efficiency of stainless steel pipes.

[0023] Optionally, the connecting seat is rotatably connected to the connecting part, and the rotation direction of the connecting seat and the sliding direction of the wiping seat are parallel to each other. The rotating shaft of the connecting seat is coaxially connected to a connecting gear, and the wiping part is connected to a connecting rack. The connecting rack meshes with the connecting gear. When the wiping part slides towards the connecting part, the connecting gear rotates, driving the spray nozzle end of the air gun to rotate towards the wiping part.

[0024] By adopting the above technical solution, when the steel pipe presses against the wiping part and drives the wiping part to slide towards the connecting part, the connecting gear meshes with the connecting rack, drives the connecting seat to rotate, drives the spray gun nozzle to rotate towards the wiping part, and the spray gun sprays airflow to the wiping part, driving the impurities on the wiping part to be discharged. Part of the airflow is guided along the wiping part to impact the steel pipe, accelerating the drying rate of the colorant on the end face of the steel pipe.

[0025] Optionally, the cleaning scraper has a guide surface on the side facing the air outlet spray gun. The inclination height of the guide surface increases as the distance to the drive rod decreases. The guide surface guides the airflow of the air outlet spray gun to impact the wiping part.

[0026] By adopting the above technical solution, when part of the airflow sprayed by the air gun is guided along the guide surface to impact the wiping part, the airflow sprayed by the air gun will stably impact the wiping part, driving the impurities on the wiping part to be discharged, thereby improving the cleaning efficiency of the wiping part. At the same time, the airflow impacts the steel pipe along the wiping part, accelerating the drying efficiency of the colorant on the steel pipe and improving the cleaning efficiency of the wiping part on the steel pipe.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The design of the wiping seat and wiping scraper eliminates the need for workers to hold a rag against the outer wall of the steel pipe to wipe away the colorant, making it less likely for the colorant on the steel pipe to contaminate the workers, thereby protecting their health and improving the safety of workers in the stainless steel pipe processing process.

[0029] 2. The air spray gun is designed to spray air that impacts the outer wall of the steel pipe and carries away impurities from the outer wall, making it less likely for impurities on the outer wall of the steel pipe to wear down the scraping end of the scraper, thereby extending the service life of the scraper.

[0030] 3. The inclusion of a connecting part, an elastic part, and a wiping part reduces friction between the steel pipe and the wiping part, making it less prone to wear and tear, thereby extending the service life of the wiping part and improving the processing quality of the steel pipe.

Detailed Implementation

[0037] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0038] This application discloses a system for spraying and wiping away colorants from stainless steel pipes. (Refer to...) Figure 1 A colorant spraying and wiping system for stainless steel pipes includes a workbench 1, a rotating assembly 2, a spraying assembly 4, and a wiping assembly 3. In this embodiment, the workbench 1 is a strip frame. The rotating assembly 2 is connected to the workbench 1 and drives the steel pipe on the workbench 1 to rotate along its own axis, with the steel pipe axis parallel to the length direction of the workbench 1. The spraying assembly 4 is slidably connected to the workbench 1, with its sliding direction parallel to the steel pipe axis. The spraying assembly 4 sprays colorant onto the outer wall of the steel pipe. The wiping assembly 3 is slidably connected to the workbench 1, with its sliding direction parallel to the sliding direction of the spraying assembly 4. The wiping assembly 3 scrapes off the colorant from the outer wall of the steel pipe after the spraying assembly 4 has sprayed it.

[0039] Reference Figure 1In this embodiment, there are multiple drive components 9, which are spaced apart and connected to the worktable 1. The arrangement direction of the drive components 9 is parallel to the length direction of the worktable 1. Each drive component 9 includes a drive plate 21, a drive motor 22, two drive rollers 23, two drive gears 24, and a drive chain 25 used in conjunction with the drive gears 24. The drive plate 21 is welded and fixed to the worktable 1. The two drive rollers 23 are rotatably connected to the drive plate 21 in sequence, with their rotation axes parallel to the axis of the steel pipe. The drive motor 22 is fixed to the worktable 1 by bolts, and its motor shaft axis is parallel to the axis of the drive roller 23. One drive gear 24 is coaxially fixed to the rotation shaft of one of the drive rollers 23, and the other drive gear 24 is coaxially fixed to the motor shaft of the drive motor 22. The drive chain 25 tensions and connects the two drive gears 24.

[0040] Reference Figure 1 When the steel pipe sprayed with colorant is placed between the two drive rollers 23, the drive motor 22 runs, driving the two drive gears 24 to rotate, which in turn drives the drive roller 23 with the drive gears 24 fixed to it to rotate, causing the steel pipe to rotate along its own axis. This drives the other drive roller 23 to rotate, so that the steel pipe can rotate stably along its own axis on the worktable 1 without the need for the operator to manually drive the steel pipe to rotate, thereby improving the processing efficiency of stainless steel pipes.

[0041] Reference Figure 1 The spray assembly 4 includes a spray base 41, a spray gun 42, and a spray tank 43. The spray base 41 is slidably connected to the workbench 1, and a spray space 411 for steel pipes to pass through is left between the spray base 41 and the workbench 1. The spray tank 43 is fixed on the spray base 41 and is used to store colorant. The spray gun 42 is connected to the spray tank 43, and the spraying end of the spray gun 42 passes through the spray base 41 and faces the spray space 411. The spray gun 42 drives the colorant in the spray tank 43 to be sprayed out from the spraying end of the spray gun 42. The colorant is evenly sprayed on the outer wall of the steel pipe in the spray space 411, realizing automatic spraying of colorant on the outer wall of the steel pipe.

[0042] Reference Figure 2 and Figure 3 The erasing assembly 3 includes an erasing base 31, an erasing scraper 32, two air-spraying guns 33, two connecting seats 34, and multiple erasing cylinders 35. In this embodiment, the erasing base 31 is a square frame and is slidably connected to the workbench 1.

[0043] Reference Figure 4The wiping scraper 32 includes a connecting part 321, an elastic part 322, and a wiping part 323. The wiping part 323 can be made of rubber or silicone. In this embodiment, the wiping part 323 is made of rubber and has a certain deformation capability. In this embodiment, the wiping part 323 is a strip plate. The connecting part 321 has a compensation cavity 3211 for sliding of the wiping part 323. The sliding direction of the wiping part 323 is parallel to the height direction of the wiping part 323, and the length direction of the wiping part 323 is parallel to the axis of the steel pipe.

[0044] Reference Figure 4 The elastic part 322 can be a compression spring or a tension spring. In this embodiment, the material of the elastic part 322 is a compression spring, which has a certain deformation capability. One end of the elastic part 322 in the direction of elastic force is welded and fixed to the inner wall of the compensation cavity 3211, and the other end of the elastic part 322 in the direction of elastic force is fixed to the wiping part 323. The direction of elastic force of the elastic part 322 and the height direction of the wiping part 323 are parallel to each other. The elastic part 322 has the tendency to drive the wiping part 323 to slide away from the connecting part 321, and the end of the wiping part 323 protruding from the connecting part 321 is used to press against the outer wall of the steel pipe and scrape off the colorant on the steel pipe.

[0045] Reference Figure 4 A connecting bolt 5 connects the erasing part 323 and the connecting part 321. The connecting part 321 has a connecting groove 3212 for the end of the connecting bolt 5 to pass through. The connecting groove 3212 is a cylindrical groove, and its axis is parallel to the width direction of the erasing part 323. The connecting groove 3212 passes through the connecting part 321 and connects to the compensation cavity 3211. The erasing part 323 has a sliding channel 3231 for the end of the connecting bolt 5 to slide. The sliding channel 3231 is a strip-shaped groove, and its length direction is parallel to the height direction of the erasing part 323. The sliding channel 3231 connects to the connecting groove 3212. The end of the connecting bolt 5 passes through the connecting groove 3212 and is embedded in the sliding channel 3231. When the erasing part 323 is slidably connected to the inner wall of the compensation cavity 3211, the connecting bolt 5 is slidably connected to the inner wall of the sliding channel 3231, so that the erasing part 323 is not easy to deviate when sliding on the inner wall of the compensation cavity 3211, thereby improving the stability of the erasing part 323 sliding on the inner wall of the compensation cavity 3211.

[0046] Reference Figure 2The erasing base 31 has a sliding groove 311 for the connecting part 321 to slide. The sliding groove 311 is a strip-shaped groove, and its length direction is parallel to the height direction of the erasing base 31. The sliding direction of the connecting part 321 is also parallel to the height direction of the erasing base 31. Multiple erasing cylinders 35 are welded and fixed to the four corners of the erasing base 31. The piston rod axis of the erasing cylinder 35 is parallel to the height direction of the erasing base 31. The piston rod of the erasing cylinder 35 passes through the erasing base 31 and is welded and fixed to the connecting part 321. The wiping cylinder 35 drives the connecting part 321 to slide along the inner wall of the slide groove 311 towards the worktable 1. The wiping part 323 presses against the outer wall of the steel pipe and scrapes off the colorant on the outer wall of the steel pipe, realizing automatic cleaning of the colorant on the outer wall of the steel pipe. It eliminates the need for workers to hold a rag and press against the outer wall of the steel pipe to wipe off the colorant, making it less likely for the colorant on the steel pipe to contaminate the workers, thereby protecting the health of the workers and improving the safety performance of the stainless steel pipe processing process.

[0047] Reference Figure 5 The connecting part 321 has two connecting cavities 3213 for the connecting seat 34 to be inserted. The two connecting cavities 3213 are located on both sides of the width direction of the wiping part 323, and both connecting cavities 3213 are connected to the compensation cavity 3211. One end of the connecting seat 34 is rotatably connected to the inner wall of the connecting cavity 3213, and the rotation axis of the connecting seat 34 is parallel to the length direction of the wiping part 323. The other end of the connecting seat 34 has a fixing hole 341 for the air spray gun 33 to pass through. When the air spray gun 33 passes through the fixing hole 341, the outer wall of the air spray gun 33 is pressed against the inner wall of the fixing hole 341 to form a fixation. The air outlet end of the air spray gun 33 is directed towards the steel pipe on the workbench 1 and sprays airflow towards the steel pipe. The airflow accelerates the drying of the colorant on the steel pipe and improves the cleaning efficiency of the colorant on the steel pipe. The connecting seat 34 is coaxially welded to the rotating shaft and the connecting gear 6 is fixed. The wiping part 323 has connecting racks 7 fixed on both sides in the width direction. The connecting racks 7 and the connecting gears 6 correspond to each other and mesh.

[0048] Reference Figure 5 When the end face of the steel pipe is uneven, the steel pipe overcomes the elastic force of the elastic part 322 and squeezes the wiping part 323 to slide towards the compensation cavity 3211, reducing the friction between the steel pipe and the wiping part 323 and reducing wear between them, thereby improving the processing quality of the steel pipe and the service life of the wiping part 323; at the same time, the connecting rack 7 and the connecting gear 6 mesh, driving the air outlet end of the air spray gun 33 to rotate towards the wiping part 323, so that the air outlet end of the air spray gun 33 faces the contact point between the wiping part 323 and the steel pipe, and the airflow sprayed by the air spray gun 33 drives the colorant at the contact point between the wiping part 323 and the steel pipe to be discharged, thereby improving the cleaning efficiency of the colorant on the steel pipe.

[0049] Reference Figure 4Two cleaning scrapers 8 are connected to the connecting part 321. The inner walls of the compensation cavity 3211 are each provided with a cleaning cavity 3214 for the cleaning scrapers 8 to slide. The two cleaning cavities 3214 are located on both sides of the wiping part 323 in the width direction. The sliding direction of the cleaning scraper 8 is parallel to the sliding direction of the wiping part 323, and the cleaning scraper 8 abuts against the wiping part 323. A waist-shaped groove 81 is provided on the cleaning scraper 8 for the connecting bolt 5 to pass through. The depth direction of the waist-shaped groove 81 penetrates the cleaning scraper 8, and the length direction of the waist-shaped groove 81 is parallel to the sliding direction of the cleaning scraper 8. The connecting groove 3212, the waist-shaped groove 81, and the sliding channel 3231 are sequentially connected.

[0050] Reference Figure 4 The cleaning scraper 8 has a guide surface 82 on its end face facing the air outlet gun 33. The guide surface 82 is arc-shaped, and its inclination height increases as the distance to the connecting part 321 decreases. The guide surface 82 is used to guide the airflow from the air outlet gun 33 to the wiping part 323. A drive assembly 9 is connected between the cleaning scraper 8 and the connecting part 321. The drive assembly 9 is used to drive the cleaning scraper 8 to slide towards the cleaning chamber 3214. The drive assembly 9 includes a drive block 91, a drive rod 92, and a drive elastic element 93. One end of the drive rod 92 is welded and fixed to the cleaning scraper 8 in the axial direction, and the other end of the drive rod 92 passes through the connecting part 321 and is welded and fixed to the drive block 91. The end of the drive block 91 away from the drive rod 92 is used to abut against the wiping seat 31, and the axis of the drive rod 92 and the height direction of the wiping part 323 are parallel to each other.

[0051] Reference Figure 4 The driving elastic element 93 can be a compression spring or a tension spring. In this embodiment, the driving elastic element 93 is a compression spring, which has a certain deformation capability. The driving elastic element 93 is sleeved on the driving rod 92. One end of the driving elastic element 93 in the direction of elastic force is fixed to the driving block 91, and the other end of the driving elastic element 93 in the direction of elastic force is fixed to the connecting part 321. The direction of elastic force of the driving elastic element 93 is parallel to the axis of the driving rod 92. The driving elastic element 93 has the elastic force to drive the driving block 91 to slide away from the connecting part 321, and the driving block 91 tends to protrude from the connecting part 321.

[0052] Reference Figure 2 and Figure 4When the connecting part 321 slides away from the worktable 1, the drive block 91 abuts against the wiping seat 31. The drive block 91 drives the drive rod 92 to slide towards the cleaning chamber 3214, causing the cleaning scraper 8 to slide along the inner wall of the sliding chamber. The cleaning scraper 8 presses against the wiping part 323 and scrapes off the colorant on the wiping part 323, thus achieving automatic cleaning of the wiping part 323. When the connecting part 321 slides towards the worktable 1, the drive block 91 disengages from the wiping seat 31. The pressure of the wiping seat 31 on the drive block 91 disappears. The elastic force of the drive elastic element 93 drives the drive block 91 to slide away from the connecting seat 34. The cleaning scraper 8 slides towards the cleaning chamber 3214. The bottom of the cleaning scraper 8 is higher than the bottom of the wiping part 323, so that the cleaning scraper 8 is less likely to interfere with the wiping part 323 scraping off the colorant on the steel pipe, thus achieving automatic cleaning of the wiping part 323.

[0053] The implementation principle of a colorant spraying and wiping system for stainless steel pipes according to an embodiment of this application is as follows: the wiping cylinder 35 drives the connecting part 321 to slide along the inner wall of the slide groove 311 towards the workbench 1, and the wiping part 323 presses against the outer wall of the steel pipe and scrapes off the colorant on the outer wall of the steel pipe, thereby realizing automatic cleaning of the colorant on the outer wall of the steel pipe. It eliminates the need for workers to hold a rag and press against the outer wall of the steel pipe to wipe off the colorant, making it less likely for the colorant on the steel pipe to contaminate the workers, thereby protecting the health of the workers and improving the safety performance of the stainless steel pipe processing process.

[0054] 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.
