Description

Technical Field

[0001] This invention relates to the field of electroplated metal strip production technology, specifically to a liquid-absorbing electroplated metal strip limiting and guiding device. Background Technology

[0002] Continuous electroplating is the mainstream processing technology for surface modification and corrosion protection of metal strips. After electroplating in the tank, a considerable amount of residual electroplating solution adheres to both the upper and lower surfaces of the metal strip. If this residual solution is not cleaned promptly and evenly, it will result in wasted electroplating solution and increased production costs. Furthermore, the residual solution remaining on the metal strip surface can easily form watermarks, color spots, color differences, and other appearance defects after drying, directly lowering the appearance quality of the electroplated product. In addition, prolonged adhesion of residual electroplating solution can also cause localized oxidation of the coating, damaging the integrity and uniformity of the coating, significantly reducing the corrosion resistance of the metal strip and the yield of the finished product. Therefore, an online liquid suction and removal device after the electroplating process is an essential part of the entire continuous electroplating production line.

[0003] Currently, conventional electroplating metal strip liquid absorption and removal equipment in the industry still has technical shortcomings in actual continuous mass production: these devices can only rely on the continuous contact of the absorbent cotton sleeve with the strip to absorb residual liquid, and the cleaning method is limited; when operating continuously for a long time, the absorbent cotton sleeve will quickly become saturated with the solution and lose its absorption capacity. Moreover, the electroplating residual liquid accumulated inside the saturated cotton sleeve cannot be discharged quickly, and the liquid absorption capacity continues to decline. It is necessary to stop the entire electroplating production line, manually remove the cotton sleeve, rinse it, squeeze it dry and restore it. The entire cleaning and restoration process is time-consuming, directly interrupting the continuous conveying rhythm of the metal strip. The production line cannot remove liquid online without interruption, which seriously restricts the continuous and stable production of the electroplating production line. Summary of the Invention

[0015] This invention provides a liquid-absorbing electroplating metal strip limiting and guiding device. Compared with the prior art, it has the following advantages: 1. Two different liquid-absorbing components are designed. Relying on the outward-folding entry and exit of the two sets of components and their lateral rotation, they can penetrate laterally into the upper and lower surfaces of the metal belt through the conveyor gap. The entire process requires no change to the metal belt's conveying trajectory or limiting guide path, avoiding interference issues such as squeezing or pushing that could occur with the continuously straight-moving metal belt. Simultaneously, the upper and lower double-suction rollers adhere to both sides of the belt, enabling simultaneous double-sided liquid wiping and adsorption. This overcomes the shortcomings of traditional single-sided liquid suction, which is often incomplete, and the potential for interference with conveying during simultaneous double-sided suction, ensuring stable metal belt conveying and comprehensive liquid removal.

[0016] 2. The two sets of liquid absorption components adopt a sequential and seamless alternating working logic. Once the absorbent cotton sleeve of one set of liquid absorption components is saturated, it immediately flips outward and retracts into the cover to enter the regeneration process. The other set flips outward and cuts into the work station to take over the liquid absorption. The metal belt conveying process is not interrupted throughout the process, taking into account both the liquid absorption and cleaning effect and the continuous production needs of the production line.

[0017] 3. Most of the electroplating residue inside the absorbent cotton sleeve is quickly discharged through mechanical extrusion, completing the centralized recycling of waste liquid; then, the entire area is rinsed with high-pressure spray using multiple built-in nozzles in the n-type fitting to remove stubborn electroplating residue embedded in the pores of the cotton sleeve.

[0021] Example To address the technical problems in the background art, the following liquid-absorbing electroplating metal strip limiting and guiding device is provided: Combination Figures 1-10 As shown, the liquid-absorbing electroplating metal strip limiting and guiding device provided by the present invention includes: a liquid-absorbing pool body 100, which has an installation window 101 on its front side, an installation cover 200 fixedly installed on the liquid-absorbing pool body 100 at the installation window 101, and a cover plate 201 movably installed on the front side of the installation cover 200. The liquid suction assembly 300 includes an active slide rail 301, a bracket 302, a first liquid suction component 303, and a second liquid suction component 304. Two sets of opposing inclined active slide rails are fixedly installed on the inner side of the cover plate 201. The first liquid suction component 303, extending into the liquid suction tank 100, is installed on the active slide rails. The bracket 302 is fixedly installed on the cover plate 201 on the side of the active slide rail 301. The second liquid suction component 304, extending into the liquid suction tank 100, is installed on the bracket 302. The first liquid suction component 303 and the second liquid suction component 304 are used to suction and guide the electroplated metal strip in the liquid suction tank 100. The cleaning assembly 400 includes an active slide rail 401, a lifting frame 402, a rinsing component 403, and a squeezing component 404. The active slide rail 401 is fixedly installed at the top inside the mounting cover 200. The lifting frame 402 is installed on the sliding part of the active slide rail 401. The rinsing component 403 and the squeezing component 404 are fixedly installed at the bottom of the lifting frame 402. The rinsing component 403 is used to rinse the liquid-absorbing component after liquid absorption, and the squeezing component 404 is used to squeeze the liquid-containing liquid-absorbing component to remove the liquid. The air-drying assembly 500 includes a fan 501, a first air-drying pipe assembly 502, and a second air-drying pipe assembly 503. The fan 501 is fixedly installed on one side of the front of the liquid absorption tank 100. The first air-drying pipe assembly 502 and the second air-drying pipe assembly 503 are respectively installed at the output end of the fan 501. The blowing end of the first air-drying pipe assembly 502 extends into the liquid absorption tank 100 and is used to air-dry the electroplated metal strip after liquid absorption. The blowing end of the second air-drying pipe assembly 503 extends into the mounting cover 200 and is used to air-dry the first liquid absorption component 303 and the second liquid absorption component 304 after cleaning. The spray assembly 600 includes a lifting component 601 and a spray component 602. The lifting component 601 is fixedly installed on the top of the liquid suction tank 100, and the spray component 602 is fixedly installed on the bottom of the lifting component 601. A liquid guide plate is fixedly installed inside the liquid suction tank 100 below the spray component 602.

[0022] In the above scheme: 1. Two different liquid-absorbing components are designed. Relying on the outward-folding entry and exit of the two sets of components and their lateral rotation, they can penetrate laterally into the upper and lower surfaces of the metal belt through the conveyor gap. The entire process requires no change to the metal belt's conveying trajectory or limiting guide path, avoiding interference issues such as squeezing or pushing that could occur with the continuously straight-moving metal belt. Simultaneously, the upper and lower double-suction rollers adhere to both sides of the belt, enabling simultaneous double-sided liquid wiping and adsorption. This overcomes the shortcomings of traditional single-sided liquid suction, which is often incomplete, and the potential for interference with conveying during simultaneous double-sided suction, ensuring stable metal belt conveying and comprehensive liquid removal.

[0023] 2. The two sets of liquid absorption components adopt a sequential and seamless alternating working logic. Once the absorbent cotton sleeve of one set of liquid absorption components is saturated, it immediately flips outward and retracts into the cover to enter the regeneration process. The other set flips outward and cuts into the work station to take over the liquid absorption. The metal belt conveying process is not interrupted throughout the process, taking into account both the liquid absorption and cleaning effect and the continuous production needs of the production line.

[0024] 3. The cleaning component 400 integrates a dual structure of extrusion component 404 and rinsing component 403. First, it quickly discharges most of the electroplating residue inside the absorbent cotton sleeve through mechanical extrusion, completing the centralized recycling of waste liquid. Then, it uses multiple built-in nozzles 433 in the n-type pipe fitting 431 to spray and rinse the entire area with high pressure, removing stubborn electroplating residue embedded in the pores of the cotton sleeve.

[0025] 4. The air drying assembly 500 is divided into two independent air drying pipelines. The first air drying pipeline group 502 delivers air in a directional manner to the metal strip after the liquid absorption is completed, quickly drying the thin liquid film remaining on the surface of the strip, avoiding watermarks, liquid spots, and surface color differences in subsequent processing of the metal strip, and improving the appearance quality of the electroplated finished product. 5. The second air drying pipe assembly 503 blows air into the mounting cover 200 to quickly dry the liquid absorption component after washing, eliminate water stains inside the cotton sleeve, and prevent water stains from diluting the electroplating solution and affecting the accuracy of the next liquid absorption.

[0026] 6. Relying on the top-mounted, liftable spray assembly 600, when the electroplating production line is temporarily stopped and the metal strip is stationary, it automatically descends to spray moisturizing liquid, continuously wetting the residual liquid on the surface of the metal strip that has not been absorbed, and preventing the electroplating solution from rapidly losing water and drying to form hard crystals.

[0027] The entire liquid absorption, cleaning, and air-drying maintenance structure is integrated inside the mounting cover 200, forming a sealed cavity with the lockable cover plate 201. The hinged structure allows for quick opening and closing, facilitating the later inspection and replacement of the internal rollers, cotton sleeves, and nozzles.

[0028] In this embodiment, a mounting ear 211 is fixedly connected to one side of the mounting cover 200, and a rotating joint 212 that is movably connected to the mounting ear 211 is fixedly connected to the cover plate 201. A positioning knob 213 is fixedly installed on one side of the cover plate 201, and the cover plate 201 is connected to the mounting cover 200 through the positioning knob. The hinged structure between the mounting ear 211 and the rotating joint 212 allows the cover plate 201 to be flexibly flipped open and closed, facilitating quick inspection and maintenance of the internal components of the cover. At the same time, the positioning knob 213 provides rigid locking after the cover plate 201 is closed, ensuring the overall airtightness of the mounting cover 200, effectively preventing corrosive electroplating mist from escaping, protecting surrounding equipment from corrosion, and balancing the equipment's airtight protection performance with convenient subsequent maintenance.

[0029] In this embodiment, the first liquid-absorbing component 303 includes a mounting base 331, a drive spindle 332, a mounting kit 333, and a motor 334. The mounting base 331 is fixedly mounted on the sliding end of the active slide rail 301. The drive spindle 332 is fixedly mounted on the mounting base 331. The mounting kit 333 is mounted on the mounting base 331 via the drive spindle 332. The motor 334 is fixedly mounted inside the mounting kit 333. The output end of the motor 334 extends out of the mounting kit 333 and is fixedly mounted on a rotating roller 335. A roller sleeve 336 is fitted on the rotating roller 335, and an absorbent cotton sleeve 337 is fixedly mounted on the roller sleeve 336. The end of the roller sleeve 336 is threaded with a limiting device that corresponds to the rotating roller 335. The second liquid suction component 304 includes a connecting frame 341, a second drive shaft 342, a gear box 343, and a second motor 344. The connecting frame 341 is rotatably mounted inside the bracket 302. The second drive shaft 342, which is rotatably connected to the bracket 302, is fixedly connected to the connecting frame 341. The gear box 343 is fixedly mounted on the connecting frame 341. The second motor 344, which is used for driving, is fixedly connected to the gear box 343. Two sets of rotating rollers 345 are rotatably mounted on the gear box 343. Roller sleeves 346 are mounted on the rotating rollers 345, and absorbent cotton sleeves 347 are fixedly mounted on the roller sleeves 346. The end of the roller sleeves 346 is threaded with a positioning knob 348 that is limited and connected to the rotating rollers 345. The first liquid suction component 303 adopts a split sliding structure, which can slide independently along the slide rail and cooperate with the flipping action; the second liquid suction component 304 adopts an integrated flipping structure, and the two are staggered in layout to adapt to the internal space of the equipment. At the same time, both sets of liquid suction rollers are equipped with detachable roller sleeves and positioning knobs, which can quickly remove and replace the absorbent cotton sleeves; each is equipped with an independent drive motor and rotating roller, which can independently control the rotation of the roller to achieve residual liquid adsorption. The two structures work together to meet the staggered installation layout and adapt to the lateral interlacing liquid suction action, improving the structural adaptability of the equipment.

[0030] In this embodiment, the rinsing component 403 includes an n-shaped pipe fitting 431, an external connector 432, and built-in nozzles 433. The n-shaped pipe fitting 431 is fixedly installed at the bottom of the mounting frame 402, and the external connector 432 is fixedly installed on the outside of the n-shaped pipe fitting 431. Built-in nozzles 433 are evenly distributed on both sides inside the n-shaped pipe fitting 431. The structure of the n-shaped pipe fitting 431 combined with the built-in nozzles 433 on both sides allows for all-around spray rinsing around the absorbent cotton sleeve, eliminating cleaning dead angles. The standardized external connector 432 on the outside facilitates quick and easy connection to an external cleaning water source, and the water circuit is easy to disassemble and assemble. It is compatible with two sets of staggered, height-adjustable liquid-absorbing components, enabling simultaneous rinsing of the entire double cotton sleeve area, improving rinsing uniformity and cleaning effect.

[0031] In this embodiment, the extrusion component 404 includes an extrusion plate 441. The extrusion plate 441 is fixedly installed at the bottom of the lifting frame 402. A first perforation 442 is provided in the middle of the extrusion plate 441. A second perforation 443 is provided on the extrusion plate 441 above and below the first perforation 442. Annular extrusion ribs 444 are fixedly installed inside the first perforation 442 and the second perforation 443. The first perforation 442 corresponds to the second liquid suction component 304; the second perforation 443 corresponds to the first liquid suction component 303. Through the active slide rail 301 arranged obliquely on the inner side of the cover plate 201, the longitudinal height of the first liquid suction component 303 can be automatically adjusted during the sliding movement of the first liquid suction component 303 into and out of the work station, so that the retracted first liquid suction component 303 and the integrated second liquid suction component 304 maintain the same longitudinal horizontal height. Without the need for an additional leveling mechanism, two sets of liquid suction components with different structures and positions can share the same cleaning assembly 400, simplifying the equipment drive structure and reducing the overall cost and control difficulty of the equipment.

[0032] In this embodiment, the first air duct assembly 502 includes a main air duct 521, an air guide cavity 522, air distribution rods 523, and air distribution nozzles 524. The output end of the fan 501 is fixedly installed with the main air duct 521. The outer side of the liquid absorption tank 100 is fixedly connected to the air guide cavity 522 extending into the interior. Two sets of connected air distribution rods 523 are fixedly installed on the air guide cavity 522 inside the liquid absorption tank 100, and connected air distribution nozzles 524 are fixedly installed on the same side of each air distribution rod 523. The air is uniformly guided by the main air duct 521, diverted by the air guide cavity 522, and then evenly distributed by multiple sets of air distribution rods 523 in conjunction with the array of air distribution nozzles 524. It can evenly diffuse high-pressure airflow across the entire width of the metal strip, achieving uniform drying across the entire area and eliminating drying dead zones; at the same time, the 524 air nozzles provide directional and stable airflow, avoiding turbulent airflow impacting the metal strip, ensuring drying efficiency without interfering with the linear guiding of the metal strip.

[0033] In this embodiment, the second air duct assembly 503 includes an air duct branch 531, an electrically controlled valve 532, and a blower nozzle 533. The air duct branch 531 is fixedly installed on the main air duct 521, and the electrically controlled valve 532 adapted for operation is fixedly installed on the air duct branch 531. The end of the air duct branch 531 extends to one side of the mounting cover 200. Four sets of blower nozzles 533 extending into the interior are fixedly installed on one side of the mounting cover 200. The blower nozzles 533 are connected to the end of the air duct branch 531, and the blower nozzles 533 correspond to the first through hole 442 and the second through hole 443. The second air drying duct group 503 is arranged to match the internal space shape of the cover. The air duct is aligned with the outline of the two liquid absorption components to deliver air in a directional manner. The airflow can accurately target the gaps and corners of the absorbent cotton cover to specifically dry the residual water stains on the liquid absorption component 300, achieving all-round air drying of the liquid absorption component without dead angles and ensuring the complete regeneration of the liquid absorption component 300.

[0034] In this embodiment, the lifting component 601 includes a fixed cover 611, a first lifting rod 612, a second lifting rod 613, and a drive gear 614. The fixed cover 611 is fixedly installed on the top of the liquid suction tank 100. The first lifting rod 612 and the second lifting rod 613 are installed through the fixed cover 611. The inner sides of the first lifting rod 612 and the second lifting rod 613 are evenly distributed with toothed grooves. The drive gear 614 is rotatably installed in the fixed cover 611 between the first lifting rod 612 and the second lifting rod 613. The spray component 602 is installed at the bottom of the first lifting rod 612 and the second lifting rod 613. The flushing component 403 and the extrusion component 404 are uniformly integrated and installed using the hoisting frame 402, ensuring that the relative positions of the extrusion station and the spraying station are constant and that they slide and align synchronously without the need for separate adjustments. The overall hoisting installation can buffer the vibration of the equipment during operation, ensuring accurate cleaning alignment. At the same time, the integrated layout reduces the space occupied and is suitable for installation environments with small internal enclosures.

[0035] In this embodiment, the spray component 602 includes an upper plate 621, a lower plate 622, and a spray element 603. The upper plate 621 is fixedly installed at the bottom of the first lifting rod 612, and the lower plate 622 is fixedly installed at the bottom of the second lifting rod 613. The upper plate 621 and the lower plate 622 are respectively provided with a water guiding chamber 624 and an assembly chamber 625. A water receiving pipe 626 connected to the water guiding chamber 624 is installed at one end of the upper plate 621 and the lower plate 622. A guide port 627 communicating with the assembly chamber 625 is provided on one side of the upper plate 621 and the lower plate 622. The spray element 603 extending out of the guide port 627 is slidably installed in the assembly chamber 625. The lifting component 601 drives the spraying component 602 to adjust up and down adaptively, which can flexibly adjust the spraying height according to the specifications of the metal strip on site and the floating range of the conveyor; always maintain the optimal spraying distance, which not only ensures that the residual liquid is fully wetted after the machine stops to prevent it from drying, but also avoids the metal strip from running off track due to the impact of high pressure water flow, and is suitable for the production of metal strips of various specifications.

[0036] In this embodiment, the spray component 603 includes a buffer box 631, a spray head 632, and a corrugated pipe 633. Multiple sets of buffer boxes 631 are slidably installed in the assembly chamber 625, and a corrugated pipe 633 connected to the water guiding chamber 624 is fixedly connected to the buffer box 631. A spray head 632 extending into a guide port 627 is fixedly installed on the outer side of the buffer box 631, and the spray head 632 is frictionally connected to the guide port 627. The spray heads 632 on the upper plate 621 and the lower plate 622 correspond to each other. By relying on the deformation of the corrugated pipe 633 and the sliding assembly structure of the buffer box 631, the spray head 632 can adaptively buffer and avoid, offsetting the displacement caused by the up-and-down jumping of the metal strip, and avoiding hard collision between the spray head 632 and the metal strip, thus preventing damage to the workpiece and the spray head; at the same time, the spray heads 632 of the upper and lower plates 622 are arranged one-to-one to ensure precise alignment of the upper and lower spray points, so as to achieve synchronous and uniform spraying and wetting of the upper and lower surfaces of the metal strip, and stably achieve the effect of preventing the electroplating solution from drying when the machine is stopped.

[0037] Working principle and usage process of this invention: In the initial state of the equipment, both sets of liquid suction components are housed inside the mounting cover 200, without contacting the metal strip and without affecting the normal linear conveying of the metal strip. First, the first liquid suction component 303 is started: the active slide rail 301 drives the bottom mounting base 331 to slide forward, and cooperates with the drive spindle 332 to complete the overall outward rotation, so that the first liquid suction component 303 extends through the mounting window 101 into the liquid suction tank 100; then, relying on the drive spindle 332, it performs a lateral rotation, driving the rotating roller 335 to rotate and align as a whole, so that the outer roller sleeve 336 and the absorbent cotton sleeve 337 are precisely inserted and attached to the lower surface of the electroplated metal strip.

[0038] The second liquid absorption component 304 is activated synchronously. The inner side of the bracket 302 drives the second main shaft 342 to rotate the side of the connecting frame 341, causing the two sets of rotating rollers 345 to laterally cut into the upper surface of the metal strip. The upper and lower sets of absorbent cotton sleeves are respectively attached to the upper and lower end faces of the metal strip. Among them, motor 1 334 and motor 2 344 drive the corresponding rotating rollers to rotate at a uniform speed. In conjunction with the metal strip being conveyed in the same direction, the absorbent cotton sleeves 337 and 347 rely on their own capillary adsorption force to simultaneously wipe and absorb the residual electroplating liquid on the upper and lower surfaces of the metal strip. The ends of the roller sleeves are locked and limited by positioning knobs 338 and 348 to prevent the roller sleeves from loosening or shifting during the conveying process, ensuring the stability of the limited guidance and liquid absorption.

[0039] The device is equipped with two independently driven, non-interfering liquid suction execution structures: a first liquid suction component 303 and a second liquid suction component 304. It adopts a time-sharing, staggered, alternating operation mode, with one component in use and the other on standby, to match the intermittent liquid suction operation requirements of the equipment. This ensures that the uniform speed limiting and guiding process of the electroplated metal strip is not disturbed throughout the entire process. After the first liquid suction component 303 continuously adheres to the upper and lower surfaces of the metal strip to absorb residual liquid until the pores of the absorbent cotton sleeve 337 are completely filled and the liquid suction capacity reaches its peak, the equipment synchronously triggers a linkage retraction command: firstly, the active slide rail 301 drives the mounting base 331 to move horizontally back, cooperating with the drive spindle 332 to complete a reverse side-tilting reset, allowing the first liquid suction component 303 to smoothly rotate out of the gap between the upper and lower parts of the metal strip. Then, it flips outward and retracts completely into the sealed position inside the mounting cover 200, completely separating from the metal strip conveying area and exiting the liquid suction operation process. At the same time that the first liquid suction component 303 begins to retract, the second liquid suction component 304 simultaneously initiates a linked outward flipping action. Relying on the internal drive spindle 342 of the bracket 302, it drives the connecting frame 341 to flip laterally, precisely cutting into the gap between the upper and lower conveyors of the metal strip, seamlessly taking over the residual liquid adsorption work. The actions of the two sets of liquid suction components are seamlessly connected, with no time gaps or movement interference. Through this alternating rotation structure, sufficient and independent time is reserved for the saturated liquid suction component for liquid removal, rinsing, and air drying regeneration, ensuring that the adsorption performance of the liquid suction component is fully restored. At the same time, it can continuously undertake the cleaning operation of residual liquid on the metal strip throughout the entire process, ensuring the continuity of the electroplating production line and fully adapting to the long-term continuous and uninterrupted conveying production conditions of electroplating metal strips.

[0040] The saturated liquid-absorbing component, retracted into the housing, enters the cleaning station. Thanks to the leveling design of the inclined active slide rail 301, the split first liquid-absorbing component 303 maintains the same longitudinal horizontal height as the integrated second liquid-absorbing component 304 after retraction. The cleaning station height of the two sets of liquid-absorbing components is uniform, eliminating the need for secondary alignment and leveling. The top active slide rail 401 drives the hoisting frame 402 to slide laterally, allowing the bottom squeezing component 404 and rinsing component 403 to accurately align with the two horizontally aligned absorbent cotton sleeves in one go. First, the squeezing component 404 descends and squeezes the absorbent cotton sleeves, quickly squeezing out most of the electroplating residue absorbed inside the cotton sleeves, completing the initial liquid removal and recovery. Then, the outer connector 432 of the n-type pipe 431 is connected to the cleaning water source. The water flows through the built-in nozzles 433 evenly arranged inside the pipe, providing high-pressure spray rinsing to the entire absorbent cotton sleeve area, removing stubborn electroplating residue in the pores of the cotton sleeve, completing the thorough water washing operation.

[0041] After cleaning, a two-stage drying process is initiated: First, the fan 501 on the outside of the liquid absorption tank 100 is activated, and the first drying pipe group 502 blows air towards the inside of the tank, providing directional strong air drying to the surface of the electroplated metal strip that has just finished absorbing liquid, quickly drying the trace residual liquid film on the surface of the strip to avoid watermarks and liquid spots in subsequent processing; Second, the second drying pipe group 503 blows air in a directional manner towards the inside of the mounting cover 200, drying the two sets of liquid absorption components that have been washed, thoroughly drying the residual cleaning water inside the absorbent cotton sleeve, allowing the liquid absorption components to quickly restore their adsorption capacity, ready for the next round of outward rotation to absorb liquid, thus realizing the recycling and regeneration of the components.

[0042] When the electroplating production line temporarily suspends its conveying process and the metal strip remains stationary at the liquid suction station, the residual electroplating solution on the surface of the metal strip that has not been absorbed is prone to rapid dehydration and drying, forming hard crystals that adhere to the surface of the strip, scratching it and being difficult to remove subsequently. At this time, the device immediately switches to a shutdown protection mode: the liquid suction component 300 remains in a retracted standby state, the lifting component 601 at the top of the tank moves downward, bringing the spray component 602 close to the top of the metal strip. The spray component 602 sprays moisturizing cleaning solution evenly over the entire area, while the lower guide plate collects the returned waste liquid, continuously wetting the surface of the stationary metal strip and preventing the electroplating residue from drying and crystallizing at the source. After the production line restarts, the spray component 600 resets, and the two sets of liquid suction components resume their alternating outward-facing liquid suction process, and the equipment returns to normal operation.

[0043] The subsequent production process repeats the above actions: after one set of liquid suction components is saturated by outward liquid suction, it is returned to be cleaned and dried, and another set takes over the work simultaneously. The metal strip is continuously limited and straightened, and the residual liquid on both sides is continuously cleaned. The rear end is simultaneously dried and shaped. The machine automatically sprays moisture when stopped and resumes work immediately when started. The whole set of equipment operates in a fully automatic closed loop without manual intervention, and is suitable for long-term continuous production of electroplated metal strips.
