Description

Technical Field

[0001] This utility model belongs to the field of pickling treatment technology for defects in stainless steel strips, and specifically relates to a pickling treatment device for eliminating roller marks defects in corrosion-resistant stainless steel strips. Background Technology

[0002] The main cause of roll marks defects in corrosion-resistant stainless steel strips is poor surface condition of the rolls during the rolling process, such as wear, scratches, or uneven roughness, as well as improper rolling process parameters, such as uneven rolling force, tension fluctuations, or speed mismatch. These factors lead to periodic or localized roll marks, streaks, or scratches on the steel strip surface. In the subsequent pickling process, the corrosion-resistant stainless steel strip with these defects needs to be thoroughly pickled to eliminate roll marks, streaks, or scratches. The aforementioned roll mark defects need to be controlled and treated using pickling technology.

[0003] A search revealed that the existing technology, authorized by publication number CN119663293A, describes a stainless steel pickling solution circulation supply mechanism and stainless steel strip pickling device. This device uses brushes to rub and scrub the stainless steel strip, improving the removal of impurities by the pickling solution. However, the single brush cannot guarantee the removal of stubborn oxide scale impurities from the stainless steel strip surface, nor can it guarantee a thorough cleaning effect. Another search revealed that the existing technology, authorized by publication number CN118668216A, describes a device and process for eliminating surface defects in stainless steel and titanium strips after pickling. This device uses two sets of squeezing and spraying components to perform squeezing and spraying on the stainless steel and titanium strip surface. However, the squeezing and spraying components alone cannot eliminate stubborn impurities on the stainless steel and titanium strip surface, and the lack of a grinding mechanism also prevents the elimination of roller marks on the surface. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a pickling treatment device for eliminating roller marks defects in corrosion-resistant stainless steel strips. The device uses a brushing mechanism to brush and sweep the upper and lower surfaces of the steel strip, loosening and removing oxide scale and other impurities. The oxide scale and impurities are then scraped off to enhance the pickling effect. A fixed-point grinding mechanism monitors the presence of roller marks and residual oxide scale on the steel strip surface, and a grinding roller performs targeted grinding on the defective locations to ensure the surface quality of the steel strip.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A pickling treatment device for eliminating roller mark defects in corrosion-resistant stainless steel strip includes a steel strip, a pickling tank, a brushing mechanism, a squeeze roller, and a fixed-point grinding mechanism. The conveying roller is located inside the pickling tank, through which the steel strip enters. The pickling tank is equipped with multiple sets of partitions, and the steel strip undergoes pickling between the partitions. The brushing mechanism is located inside the pickling tank, with the squeeze roller positioned behind it, and the fixed-point grinding mechanism positioned behind the squeeze roller. During the pickling process, the brushing mechanism brushes and scrapes the steel strip to remove oxide scale and impurities. The squeeze roller squeezes the acid from the surface of the strip. The fixed-point grinding mechanism then detects and grinds the roller mark defects. After removing the roller mark defects, the steel strip is conveyed forward by the conveying roller and re-enters the pickling tank for pickling, completing the steel strip treatment.

[0007] The washing mechanism includes a centering mechanism, a connecting plate I, a scraping mechanism, a transmission mechanism, a protective shell, and brush rollers. The centering mechanism is located on one side of the washing mechanism and is connected to the connecting plate I. The connecting plate I is equipped with the scraping mechanism.

The transmission mechanism is connected to the brush rollers, and the brush rollers are rotatably connected to the connecting plate I. The centering mechanism adjusts the positions of the upper and lower sets of brush rollers so that the brush rollers can be close to the middle steel strip. The scraping mechanism scrapes off the oxide scale and impurities on the steel strip. The transmission mechanism provides power for the rotation of the brush rollers. The brush rollers sweep and remove the oxide scale and other impurities on the steel strip, promoting the pickling effect. The protective shell provides protection for the transmission mechanism, preventing acid and oxide scale and other impurities from affecting the operation of the transmission mechanism.

[0008] The centering mechanism includes a motor I, a positioning seat, a transmission shaft I, and a transmission shaft II. Motor I is fixed to the outside of the pickling tank. The output end of motor I is connected to helical gear I, which meshes with two sets of helical gears II. Helical gears II are located at one end of transmission shaft I.

A connecting plate I is mounted on transmission shaft II, and transmission shaft II is fixedly connected to connecting plate I. The other end of transmission shaft II is fixed to the protective shell. Motor I controls the rotation of helical gear I, which meshes with helical gear II. Helical gear II drives transmission shaft I to rotate, which in turn drives helical gear III to rotate. Helical gear III meshes with helical gear IV, which in turn drives transmission shaft II to rotate. Transmission shaft II causes connecting plate I to swing, and connecting plate I causes brush rollers to swing. The upper and lower sets of brush rollers clamp and center the intermediate steel strip, bringing the brush rollers close to the surface of the steel strip.

[0009] The transmission mechanism includes a motor II, a transmission shaft III, a positioning shaft, and a transmission shaft IV. The motor II is fixed to the outside of the pickling tank. The output end of the motor II is connected to the transmission shaft III. Gear I is mounted on the transmission shaft III and meshes with gear II. Gear II is mounted on the positioning shaft and rotatably connected to the positioning shaft. The positioning shaft is located inside the protective shell. Gear II meshes with gear III. Gear III is connected to the transmission shaft IV. The transmission shaft IV passes through the protective shell and connects to the brush roller. The motor II controls the rotation of the transmission shaft III, which drives the gear I to rotate. Gear I meshes with gear II, gear II meshes with gear III, gear III drives the transmission shaft IV to rotate, and the transmission shaft IV drives the brush roller to rotate. The brush roller brushes the surface of the steel strip.

[0010] The scraping mechanism includes a motor III, a drive shaft V, a positioning plate, a scraper, a limiting shaft I, and a spring. Motor III is fixed to a connecting plate I, and its output end is connected to the drive shaft V. The positioning plate is mounted on the drive shaft V and fixedly connected to it. A scraper is located at the lower end of the positioning plate and is slidably connected to it. A fixing plate I is fixed to the positioning plate, and a fixing plate II is fixed to the scraper. The limiting shaft I passes through the fixing plate I and is fixed to the fixing plate II, and is slidably connected to the fixing plate I. Positioning shaft I is fixedly connected to fixed plate II. A spring is provided between fixed plate I and fixed plate II. The spring is also sleeved on limiting shaft I and is slidably connected to limiting shaft I. Motor III controls the rotation of transmission shaft V, which drives the positioning plate to rotate. The rotation of the positioning plate drives the scraper to rotate and press down. Through the spring, it contacts fixed plate II. Fixed plate II drives the scraper to press down. Fixed plate I and limiting shaft I ensure the downward pressing range of the scraper. The scraper presses the middle steel strip and scrapes off the oxide scale and impurities on the surface of the steel strip.

[0011] The fixed-point grinding mechanism includes motor IV, a lead screw, an angle stepper motor, a CCD camera, a baffle plate, an electric push rod, motor V, and a grinding roller. Motor IV is fixed to the outside of the pickling tank. The output end of motor IV is connected to the lead screw. A baffle plate is provided below the lead screw.

[0012] Motor IV controls the rotation of the lead screw, which works in conjunction with a lead block. The rotation of the lead screw drives the lead block to move, which in turn drives connecting plates II and III to move. Connecting plate II then drives the CCD camera to move. An angle stepper motor controls the angle of the CCD camera, which monitors the surface quality of the steel strip, detecting the presence of roller marks and residual oxide scale. Connecting plate III drives the electric actuator to move. When the CCD camera detects a defect on the steel strip surface, the electric actuator controls the lifting frame to rise and fall. The lifting frame then drives the grinding roller to rise and fall, bringing the grinding roller closer to the steel strip surface. Motor V controls the rotation of the grinding roller, which grinds the defective areas on the steel strip surface. A baffle plate below the lead screw prevents impurities from splashing during grinding from contaminating the lead screw and lead block, thus affecting their coordinated movement.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] The centering mechanism in the brushing system controls the upper and lower sets of brush rollers as needed to clamp and center the middle steel strip, ensuring that the brush rollers can simultaneously approach the upper and lower surfaces of the steel strip. In conjunction with the transfer mechanism, the brush rollers rotate, simultaneously brushing the upper and lower surfaces of the steel strip to ensure brushing quality. This loosens and removes oxide scale and other impurities from the steel strip surface. Then, the scraping mechanism in the brushing system simultaneously presses the middle steel strip, scraping away the oxide scale and impurities, enhancing the pickling effect. Furthermore, the simultaneous centering of the brush rollers and scraper in the brushing system minimizes the risk of steel strip deformation during oxide scale removal. The fixed-point grinding mechanism monitors the surface quality of the steel strip using a CCD camera, detecting the presence of roller marks and residual oxide scale. The grinding roller then performs targeted grinding on the defective areas of the steel strip surface to ensure surface quality. Attached Figure Description
