Description

Technical Field

[0001] This invention relates to the field of steel plate corrosion resistance testing technology, and specifically to a steel plate corrosion resistance testing device. Background Technology

[0002] Steel plates are an indispensable basic metallic material in industrial production, construction, and machinery manufacturing. The corrosion resistance of the material itself directly determines the service life, structural stability, and safety of the steel plate. Therefore, after the steel plate is rolled and cooled, it must be sampled for corrosion resistance testing. The routine testing process includes multiple steps such as sampling, sample preparation, salt spray testing, visual inspection, and internal flaw detection. The degree of automation, testing accuracy, and operational continuity of the testing equipment directly affect the overall production cycle and the quality of the finished steel plate.

[0003] Currently, the traditional method for corrosion resistance testing of rolled steel plates in the industry is manual offline testing. This involves staff manually taking samples from the cooled steel plate material, manually cutting them into test strips using cutting equipment, and then manually transporting the cut steel plate samples to the laboratory to complete the testing process, including salt spray testing, visual observation, and flaw detection.

[0004] Traditional testing methods have the following problems: In the sampling and sample preparation stage, steel plate materials still need to be manually extracted from the production line, manually transported and positioned, and then cut and prepared. This not only results in high labor intensity and low sampling and sample preparation efficiency, but also reduces the accuracy of sample preparation due to manual cutting and positioning errors. Furthermore, the transport of cut sample strips lacks a dedicated conveying structure, making transport inconvenient. In the salt spray test stage, traditional salt spray test equipment mostly uses a single sample placement test structure, which cannot conduct parallel tests on multiple batches of sample strips at the same time. This results in low testing efficiency, and the salt spray can only contact the sample surface on one side, leading to uneven salt spray adhesion and reducing the accuracy of corrosion test data.

[0023] 4. The testing component features an integrated design that combines sample drying, appearance inspection, rust layer grinding, flaw detection, and temporary storage / unloading, eliminating the need for separate steps and improving testing efficiency.

Detailed Implementation

[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, 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.

[0050] To address the technical problems in the background section, the following device for testing the corrosion resistance of steel plates is provided:

[0051] Combination Figures 1-18 As shown, the present invention provides a steel plate corrosion resistance testing device, the overall structure of which includes a cooling platform 100, a transfer component 200, a sample preparation component 300, a salt spray test component 400, and a testing component 500, the specific structural layout of which is as follows:

[0052] The cooling platform 100 and the transverse output rollers 110 are used to carry and longitudinally output rolled steel plates along the width direction, providing a cooling and conveying channel for the steel plates. The output end of the cooling platform 100 is equipped with multiple sets of transverse output rollers 110, which are arranged horizontally at intervals to output the cooled steel plates one by one along the length direction, realizing the normal production conveying of the steel plates. If the steel plates do not need to be sampled, they can be directly conveyed to the next production process through the transverse output rollers 110. A gap is reserved between the transverse output rollers 110 for the transfer component 200 to extend into, realizing the sampling and transfer of steel plates that need to be sampled.

[0053] The transfer component 200 is used to periodically longitudinally export a set of steel plates for sample preparation, and after the sample preparation is completed, guide the remaining steel plates back to the transverse output roller 110 to realize the coordinated operation of sampling inspection and normal production. Its input end is arranged opposite to the output end of the cooling platform 100, and the input end is placed between the transverse output rollers 110. The transfer assembly 200 includes a longitudinal conveyor belt 230, a transverse support plate 220, and a first drive rod 210. Multiple sets of longitudinal conveyor belts 230 are arranged laterally at intervals, evenly distributed. The input end of each longitudinal conveyor belt 230 extends between adjacent transverse output rollers 110, facilitating the receipt of steel plates transferred from the transverse output rollers 110. The bottom of each set of longitudinal conveyor belts 230 is provided with a transverse support plate 220, which supports and fixes the longitudinal conveyor belts 230. The bottom surface of the transverse support plate 220 is provided with a vertically arranged first drive rod 210, which drives the transverse support plate 220 and the longitudinal conveyor belts 230 to lift or lower. When lifted, the steel plate can be transferred from the transverse output rollers 110 to the longitudinal conveyor belt 230; when lowered, it can detach from the transverse output rollers 110, avoiding disruption to normal transport.

[0054] The sample preparation component 300 is used to cut and prepare samples from the sampled steel plates to obtain test strips. It includes a first transposition component, a side fixing plate 320, a transverse guiding component 330, a lifting component 360, a pushing component, and a cutting component 340. The components work together to achieve automatic positioning, cutting, and guiding of the test strips.

[0055] Specifically, the first transposition component is used to adjust the transverse guide component 330 to different output positions to adapt to the feeding position of the salt spray test assembly 400. It includes multiple sets of longitudinally extending first transposition guide rails 310, which are arranged in parallel. An L-shaped side fixing plate 320 is slidably installed on the top. The side fixing plate 320 can slide longitudinally along the first transposition guide rails 310 to achieve position adjustment.

[0056] Specifically, the transverse guiding component 330 is used to guide the steel plate and the sample strip. It includes a flat support roller 331 and a side guide roller 333. The flat support roller 331 is arranged in a transverse linear array on the top of the inner wall of the side fixing plate 320 to horizontally support the steel plate and the sample strip and reduce friction during transportation. The top of the side fixing plate 320 is provided with a hanging cover 332. The bottom surface of the hanging cover 332 is arranged in a transverse linear array with vertically arranged side guide rails. The end face of the area to be cut of the steel plate is attached to the side guide rails to play a positioning role, avoid the steel plate from shifting during cutting, and ensure the sample preparation accuracy.

[0057] Specifically, the lifting component 360 is used to lift the extended steel plate to be cut, facilitating the cutting component 340 to perform the cutting. It includes multiple sets of supports 363, which are located between adjacent flat rollers 331 and do not affect the guiding action of the flat rollers 331. The multiple sets of supports 363 are located on the top of the base rod 362. A second drive rod 361 is installed on the bottom surface of the base rod 362. When the second drive rod 361 extends or retracts, it drives the base rod 362 and the supports 363 to move up and down. When lifted, the supports 363 are higher than the flat rollers 331, lifting the steel plate to be cut. After cutting, they descend so that the strip is placed on the flat rollers 331 for subsequent guiding.

[0058] Specifically, the cutting component 340 is used to perform transverse cutting on the end of the steel plate to obtain a sample strip. It includes a first transverse guide rail 341 and a cutting head 342. The first transverse guide rail 341 is horizontally arranged, and the cutting head 342 is vertically arranged and slidably installed on the side. The cutting head 342 can move laterally along the first transverse guide rail 341. It adopts laser cutting or flame cutting method, which has high cutting accuracy and high efficiency, and can quickly cut out a sample strip that meets the testing requirements.

[0059] Specifically, the pushing component 350 is used to push out the sample strip on the flat idler roller 331 and transport it to the salt spray test assembly 400. It includes a second horizontal guide rail 351, a bending rod 352, and a push plate 353. The second horizontal guide rail 351 is located at the bottom of the first horizontal guide rail 341 and is arranged parallel to the first horizontal guide rail 341. The bending rod 352 is slidably installed on the side of the second horizontal guide rail 351. The end of the bending rod 352 is provided with a push plate 353. The push plate 353 is flush with the top surface of the flat idler roller 331. When the push plate 353 moves along the second horizontal guide rail 351, it can smoothly push out the sample strip on the top of the flat idler roller 331, realizing the automatic transport of the sample strip.

[0060] The salt spray test assembly 400 is used to conduct corrosion resistance salt spray tests on samples, simulating harsh environments and detecting the corrosion of the samples. It includes a main housing 410, an inspection door 420, a feeding component 430, a discharging component 460, a spraying component 450, and a rotating component 440. It can process multiple batches of samples simultaneously, resulting in high testing efficiency.

[0061] The main chamber 410 is a closed space for salt spray testing. An inspection door 420 is provided at the input end of the main chamber 410 for easy equipment inspection and maintenance. Multiple sets of feeding components 430 are built into the inspection door 420. An output component 460 is provided at the output end of the main chamber 410, positioned opposite the feeding components 430. The feeding components 430 are used for inserting the sample, and the output component 460 is used for outputting the sample after the test. A spraying component 450 is installed inside the main chamber 410 to spray salt spray, simulating a corrosive environment. A rotating component 440 is installed between each set of feeding components 430 and output components 460. The rotating component 440 drives the sample to rotate, ensuring that all surfaces of the sample are evenly contacted with the salt spray, thus ensuring test accuracy. The feeding components 430 and output components 460 constrain and position the sample from both ends to prevent deviation during rotation.

[0062] Specifically, the feeding component 430 and the discharging component 460 adopt the same structure to ensure consistent positioning when the sample enters and exits. The feeding component 430 includes a sealing plate 434, a third drive rod 431, an inner extension plate 432, a tilting gear 435, a locking element 436, an L-shaped rod 433, a drive gear plate 437, and a support shaft 438. The output end of the third drive rod 431 is connected to the inner extension plate 432 to drive the inner extension plate 432 to move inward and outward. The inner end of the inner extension plate 432 is rotatably equipped with a tilting gear 435, and the bottom surface of the inner extension plate 432 is equipped with a locking element 436 that elastically locks the tilting gear 435. The locking element 436 can elastically abut against the tilting gear 435 to prevent the tilting gear 435 from rotating on its own. The end of the tilting gear 435 is connected to the L-shaped rod 433, and one side of the inner extension plate 432 is equipped with a... The drive gear plate 437 is located on the outer side of the flip gear 435. When the inner extension plate 432 moves outward, the flip gear 435 meshes with the drive gear plate 437, causing the flip gear 435 to rotate. The bottom end of the L-shaped rod 433 is connected to the sealing plate 434, which is used to seal the material hole 421 of the inspection door 420. A support shaft 438 is rotatably installed in the middle of the inner wall of the sealing plate 434. The support shaft 438 abuts against the spline, which plays a role in positioning and support. Three sets of material holes 421 are opened inside the inspection door 420. The sealing plate 434 cooperates to seal the material holes 421. The third drive rod 431 and the drive gear plate 437 are both fixed to the outer wall of the inspection door 420 and are firmly installed.

[0063] Specifically, the rotating component 440 is used to drive the specimen to rotate, ensuring that all surfaces of the specimen are in uniform contact with the salt spray. It includes end plates 441, series plates 445, inner support rings 444, end rings 442, driven gear rings 443, intermediate gear sets 448, main drive shaft 411, constraint roller frame 446, and bearing seats 447. The end plates 441 are symmetrically arranged, with two sets of end plates 441 vertically positioned on the inner bottom surface of the main housing 410, providing support. End rings 442 are rotatably mounted inside the end plates 441. Driven gear rings 443 are provided on the outer wall of the end rings 442, and the driven gear meshes with the intermediate gear sets 448. The intermediate gear sets 448 penetrate the main housing 410 and are used to transmit power. Each set of intermediate gear sets 448 meshes with the main drive shaft 411, which is located on the outside of the main housing 410 and is connected from the outside. The power drive can simultaneously rotate multiple sets of intermediate rotating gear sets 448; two sets of series plates 445 are installed between the two sets of end plates 441, and multiple sets of inner support rings 444 are provided between the two sets of series plates 445. Four sets of annularly arranged constraint roller frames 446 are installed inside the inner support rings 444 and the end rings 442 to constrain and position the spline and prevent the spline from shifting; the spline passes through the end rings 442 and the inner support rings 444, and the inner support rings 444 are placed on the bearing seats 447 to ensure that the inner support rings 444 rotate smoothly.

[0064] Specifically, the spray component 450 is used to spray salt spray into the main housing 410. It includes a main pipe 453, vertical branch pipes, nozzles 452, a liquid pump 454, and a liquid tank 451. Multiple sets of main pipes 453 are arranged parallel to each other at the bottom of the rotating component 440 and are evenly distributed. Multiple sets of vertical branch pipes are connected in parallel to the top of the main pipes 453. The top of the vertical branch pipes is equipped with nozzles 452, which can atomize the salt solution and spray it out to ensure uniform distribution of salt spray. Multiple sets of main pipes 453 are connected in parallel to the liquid pump 454. The input end of the liquid pump 454 is connected to the liquid tank 451, which is used to store salt solution. The liquid pump 454 draws out the salt solution from the liquid tank 451 and delivers it to the main pipes 453 and vertical branch pipes, and sprays it out through the nozzles 452 to realize the salt spray test.

[0065] The detection component 500 is used to perform comprehensive inspections on the samples after the salt spray test, including appearance inspection and flaw detection, to ensure inspection accuracy. It includes a second transposition component, a temporary storage component 520, a feed hood 540, a drying component, a first detection component, a grinding component, a second detection component 590, and a discharge component 530. All components work together to achieve automated inspection and temporary storage of the samples.

It includes the second transposition guide rail 510, which is horizontally arranged to provide a moving track for the temporary storage component 520.

[0067] Specifically, the temporary storage component 520 is used to temporarily store the tested samples and includes a temporary storage tank 521, an output drive roller 522, a baffle 524, a support plate 523, and a storage rack 550. Multiple sets of output drive rollers 522 are installed at intervals inside the temporary storage tank 521 to guide the samples. A baffle 524 is provided at the outer end of the temporary storage tank 521 to prevent the samples from falling. A support plate 523 is provided on the bottom surface of the temporary storage tank 521, and the bottom of the support plate 523 is slidably embedded in the second transposition guide rail 510, allowing the temporary storage tank 521 to move along the second transposition guide rail 510. A storage rack 550 is provided on one side of the temporary storage tank 521 to collect the tested samples.

[0068] Specifically, the unloading component 530 is used to eject the sample strip from the temporary storage tank 521 and discharge it to the storage rack 550. It includes multiple sets of inclined top plates 531, support rods 535, top plates 533, top racks 534, and a fourth drive rod 532. Each set of inclined top plates 531 is positioned between adjacent output drive rollers 522, without affecting the rotation of the output drive rollers 522. Each set of inclined top plates 531 has a support rod 535 at its bottom. 5 is vertically mounted on the surface of the top plate 533, and the top plate 533 is placed parallel to the bottom of the multiple sets of output active rollers 522; the bottom surface of the top plate 533 is connected to the fourth drive rod 532 through the top frame 534. When the fourth drive rod 532 extends or retracts, it drives the top frame 534, the top plate 533 and each inclined top plate 531 to lift or lower. When lifted, the inclined top plate 531 lifts the sample strip, so that the sample strip passes through the temporary storage groove 521 and is discharged to the storage rack 550.

[0069] Specifically, the air-drying component is used to air-dry the sample to avoid liquid interference with the accuracy of appearance inspection. It includes an exhaust ring frame 560, an air inlet pipe 561, and a hot air host 541. The exhaust ring frame 560 is located at the inner inlet end of the feed hood 540 and surrounds the sample transport path. The top of the exhaust ring frame 560 is connected to the air inlet pipe 561, which is connected to the hot air host 541. The hot air generated by the hot air host 541 is transported to the exhaust ring frame 560 through the air inlet pipe 561 and blown evenly onto the sample to quickly dry the residual salt solution on the surface of the sample.

[0070] Specifically, the first detection component is used to photograph the appearance of the sample strip at one time and record the initial rust appearance of the sample strip after the salt spray test. It includes a first industrial camera 570, which is symmetrically arranged in two sets, to photograph the top and bottom surfaces of the sample strip respectively, to ensure comprehensive imaging and obtain the first appearance image for subsequent comparative analysis.

[0071] Specifically, the grinding components are used to remove and collect the rust layer on the sample surface to obtain rust powder and avoid the rust layer interfering with the accuracy of flaw detection. These components include a grinding box 580, grinding belts 582, a powder collection tank 583, a powder suction pipe 584, a ventilation unit 542, and a material box 543.

The grinding box 580 has symmetrically arranged grinding belts 582 inside, which grind the top and bottom surfaces of the sample respectively. The grinding belts 582 move in the following directions... The output direction is opposite to that of the spline to ensure thorough grinding. Each set of grinding belts 582 is equipped with a powder collection tank 583 at its input end to collect rust powder generated during grinding. The input end of the grinding box 580 is connected to a powder suction pipe 584, which is used to extract the rust powder from the powder collection tank 583. The output end of the powder suction pipe 584 is connected to the exhaust fan 542, which has a built-in material box 543.

The secondary appearance images are compared with the primary appearance images to further determine the corrosion status of the sample. It includes a second industrial camera 591 and an ultrasonic probe 592. The second industrial camera 591 is symmetrically arranged in two sets, which respectively capture the top and bottom surfaces of the polished sample to obtain the second appearance images.

The top of the ultrasonic probe 592 is equipped with a spring rod 595, and the top of the spring rod 595 is equipped with a slider 594. The slider 594 is slidably embedded in the moving guide rail 593.

[0073] Working principle and usage process of this invention:

[0074] S1. Steel plate sampling:

[0075] The rolled steel plates are output longitudinally along the width direction of the cooling platform 100 and cooled on the cooling platform 100. After cooling, the steel plates are transported to the output end of the cooling platform 100. If the steel plates do not need to be sampled, they are directly output one by one along the length direction through the transverse output rollers 110 to the next production process. If the steel plates need to be subjected to corrosion resistance and ultrasonic testing, the first drive rod 210 is activated, driving the transverse support plate 220 and multiple sets of longitudinal conveyor belts 230 to lift. The longitudinal conveyor belts 230 extend between adjacent transverse output rollers 110, transferring the steel plates to be sampled from the transverse output rollers 110 to the longitudinal conveyor belts 230, thus completing the steel plate sampling.

[0076] S2. Steel plate sample preparation:

[0077] The sample preparation assembly 300 is activated, and the second drive rod 361 drives the bottom rod 362 and multiple sets of supports 363 to rise, making the supports 363 higher than the flat rollers 331, which facilitates the lifting of the steel plate to be cut area; then, the longitudinal conveyor belt 230 is activated, outputting the sampled steel plate, the end face of the steel plate abuts against the side guide rollers 333 to achieve positioning, and the end of the steel plate is stably placed on the top of each set of supports 363, ensuring that the area to be cut is accurately aligned with the cutting head 342; then, the cutting head 342 moves along the first transverse guide rail 341 Laterally, the steel plate is cut laterally using laser cutting or flame cutting to obtain a sample that meets the testing requirements. After cutting, the longitudinal conveyor belt 230 rotates in the opposite direction to send the remaining steel plate back to the transverse output roller 110 for continued transport to the next process. At the same time, the second drive rod 361 drives the bottom rod 362 and the support 363 to descend. The support 363 is lower than the flat support roller 331, so that the cut sample is placed stably on the flat support roller 331, completing the sample preparation.

[0078] S3, Spline transport:

[0079] The first shifting guide rail 310 drives the L-shaped side fixing plate 320 to move longitudinally, adjusting the position of the transverse guiding component 330 so that the strip on the flat roller 331 is precisely aligned with the idle rotating component 440 inside the salt spray test assembly 400. Then, the feeding component 430 of the salt spray test assembly 400 is activated, and the third drive rod 431 drives the inner extension plate 432 to move outward, causing the sealing plate 434 to disengage from the material hole 421 of the inspection door 420. As the inner extension plate 432 continues to move outward, the flipping gear 435 meshes with the top drive tooth plate 437, and the flipping gear 435 rotates, causing the L-shaped rod 433 and the sealing plate 434 to rotate upward, completely opening the material hole 421. At this time, the locking component 436 elastically resists the flipping gear 435 to prevent flipping. Gear 435 rotates on its own to ensure that material hole 421 remains open. Subsequently, the pushing component is activated, and push plate 353 moves along the second horizontal guide rail 351 to push the sample strip on flat support roller 331. The sample strip passes through material hole 421, end ring 442, and inner support ring 444 in sequence. Each set of constraint roller frames 446 constrains and positions the sample strip from all sides to ensure its stability. After the sample strip is pushed, the third drive rod 431 drives the inner extension plate 432 to retract inward. The flipping gear 435 separates from the drive tooth plate 437, and the locking member 436 locks the flipping gear 435. The sealing plate 434 rotates downward to reseal the material hole 421. At the same time, the support shaft 438 on the inner wall of the sealing plate 434 abuts against the sample strip from both ends to achieve the positioning and fixation of the sample strip, thus completing the sample strip conveying.

[0080] S4. Salt spray test:

[0081] After the sample bar positioning is completed, the salt spray test is initiated. The liquid pump 454 starts, drawing out the salt solution from the liquid tank 451 and delivering it to the nozzle 452 through multiple main pipes 453 and vertical branch pipes. The nozzle 452 atomizes the salt solution and sprays it into the main chamber 410. At the same time, the temperature control element in the main chamber 410 is activated to adjust the temperature inside the chamber, simulating a harsh corrosive environment. Multiple samples from different production batches can be placed simultaneously on multiple rotating components 440 inside the main chamber 410 to complete the salt spray test synchronously, significantly improving test efficiency. During the test, external power drives the main transmission... The rotating shaft 411 drives the main drive shaft 411 to drive multiple sets of intermediate rotating gears 448 to rotate synchronously. Each set of intermediate rotating gears 448 drives the corresponding driven gear ring 443 to rotate. The driven gear ring 443 drives the end ring 442, the connecting plate 445, and the inner support ring 444 to rotate synchronously. The bearing seat 447 supports the inner support ring 444 to ensure smooth rotation. When the inner support ring 444 and the end ring 442 rotate, they drive the sample strip that passes through them to rotate, so that all surfaces of the sample strip can be evenly contacted with the salt spray, ensuring the accuracy of the salt spray test and avoiding detection errors caused by uneven local contact.

[0082] S5, Spline inspection:

[0083] When a set of samples reaches the preset salt spray test time, the corresponding feeding component 430 and discharging component 460 of that sample open simultaneously. The second shifting guide rail 510 drives the temporary storage groove 521 of the temporary storage component 520 to move, precisely aligning with the discharge position of that sample. Subsequently, the next set of samples to be tested is fed into the corresponding rotating component 440 through the feeding component 430. The new sample pushes the tested sample, causing the tested sample to be output through the discharging component 460 into the temporary storage groove 521. After entering the temporary storage groove 521, the sample contacts the output drive roller 522 inside the temporary storage groove 521. The rotating output drive roller 522 drives the sample to be conveyed along the temporary storage groove 521 and enters the feeding hood 540, starting the full-process testing.

[0084] First, the drying components are activated. The hot air generated by the hot air host 541 is delivered to the exhaust ring frame 560 through the air inlet pipe 561. The exhaust ring frame 560 blows hot air evenly onto the sample strip to quickly dry the residual salt solution on the surface of the sample strip and avoid liquid residue interfering with the accuracy of subsequent appearance inspection.

[0085] Subsequently, the first detection component is activated, and the two sets of first industrial cameras 570 simultaneously capture the top and bottom surfaces of the sample to obtain the first appearance image and record the initial rust appearance of the sample after the salt spray test.

[0086] The sample continues to be fed into the grinding box 580. The two sets of grinding belts 582, which are symmetrically arranged inside the grinding box 580, are started to grind the top and bottom surfaces of the sample respectively. The movement direction of the grinding belts 582 is opposite to the output direction of the sample to ensure that the rust layer on the surface of the sample is completely removed. The rust powder generated by grinding is collected in the powder collection groove 583 at the input end of the grinding belts 582.

[0087] After grinding, the sample continues to be conveyed, and the second inspection component 590 is activated. The upper and lower sets of second industrial cameras 591 capture the top and bottom surfaces of the sample to obtain a second appearance image. The control system compares the second appearance image with the first appearance image to more accurately determine the degree of corrosion of the sample. At the same time, the moving guide rail 593 drives the ultrasonic probe 592 to move back and forth. The ultrasonic probe 592 performs comprehensive ultrasonic flaw detection on the sample to determine whether there are defects such as corrosion and cracks inside the sample, ensuring comprehensive and accurate detection.

[0088] After the test is completed, the sample is transported to the temporary storage tank 521 to complete the sample test.

[0089] S6. Sample cutting and rust powder collection:

[0090] After a set of sample strips has been tested, the entire sample strip is placed stably on the output drive roller 522 of the temporary storage tank 521; the second shift guide rail 510 drives the temporary storage tank 521 to move, precisely moving the temporary storage tank 521 to the top of the storage rack 550; then, the fourth drive rod 532 is activated, driving the top material rack 534, the top material plate 533 and each inclined top plate 531 to lift up, the inclined top plate 531 pushes the sample strip upward, so that the sample strip passes over the baffle 524 of the temporary storage tank 521 and slides down along the inclined top plate 531 onto the storage rack 550, completing the sample strip unloading;

[0091] During the unloading process, the exhaust fan 542 is continuously activated, drawing out the rust powder from the powder collection tank 583 through the powder suction pipe 584. The rust powder is drawn into the material box 543 of the exhaust fan 542, achieving centralized collection of the rust powder. After a set of sample strips is unloaded, the material box 543 can be pulled out, and the rust powder in the material box 543 can be poured into the corresponding independent packaging bag for subsequent independent testing, avoiding rust powder contamination of the working environment.
