Description

Technical Field

[0001] This application relates to the field of coating apparatus technology, and more particularly to a wiping device for the surface of a coating steel roller. Background Technology

[0002] In the lithium battery manufacturing process, the uniformity and thickness accuracy of electrode coating are key factors affecting battery cycle life, rate performance, and safety. The coating steel roller, as the core component of the coating process, functions to uniformly and stably coat the electrode slurry onto the surface of the metal foil substrate, forming an electrode coating that meets the required thickness and precision.

[0003] Currently, in the double-layer electrode coating process, the first layer of the electrode is usually in a semi-dry state after exiting the oven. When it enters the second coating layer, it is very prone to adhering to the surface of the steel roller, leading to problems such as imprinting, surface defects, and even scraping. The roller adhesion phenomenon not only affects the surface quality of the electrode but also causes uneven coating, which in turn leads to a decrease in battery performance and safety risks.

[0004] To address the issue of roller sticking, the industry has proposed several steel roller cleaning solutions. These include installing a cleaning mechanism on the opposite side of the coating and dipping rollers, using gauze outside the positioning cylinder for cleaning; and employing scraping and adjusting components to scrape away residual coating from the outer wall of the coating roller using a cleaning plate on the cleaning roller. While existing technologies offer various roller surface cleaning solutions, improvements are still needed. Some cleaning devices may damage the precision roller surface while removing stains. Existing cleaning mechanisms are often designed for specific equipment and have poor adaptability to coating steel rollers of different diameters, lengths, and speeds. Some cleaning devices require complex disassembly and assembly processes, impacting production efficiency and increasing equipment maintenance time. In summary, existing coating steel roller cleaning technologies still have room for improvement in terms of cleaning effectiveness, device adaptability, and ease of operation. Therefore, a wiping device that can be quickly disassembled, effectively cleaned, and without damaging the roller surface is needed to meet the high-efficiency maintenance requirements of lithium battery production lines for coating steel rollers.

[0005] This application provides a surface wiping device for coating steel rollers. Its purpose is to achieve rapid clamping and driving rotation of the coating steel roller through the cooperation of a movable vertical plate and a rotating shaft assembly. Simultaneously, by utilizing a liftable and detachable cleaning wet wiping strip structure, effective wiping and convenient maintenance of the steel roller surface are achieved, thus solving the problems of low cleaning efficiency and inconvenient operation in existing technologies. This application achieves its purpose through the following technical solution: the surface wiping device for coating steel rollers of this application includes a base plate, a first vertical plate, a second vertical plate, a lifting plate, a strip plate, a cleaning wet wiping strip, and a rotating shaft assembly. The first vertical plate is fixedly mounted on the base plate, and the second vertical plate is movably mounted on the base plate. The first vertical plate and the second vertical plate are respectively provided with a rotating shaft assembly. The rotating shaft assembly includes a limiting rotating block, which matches the end insert shaft of the coating steel roller body. The rotating shaft assembly on the first vertical plate and the rotating shaft assembly on the second vertical plate are arranged opposite to each other for clamping and driving the coating steel roller body to rotate. The lifting plate is height-adjustable and is mounted on the base plate. The strip plate is detachably mounted on the lifting plate. The cleaning wet wiping strip is mounted on the strip plate.

[0006] In one embodiment, the drive motor is mounted on the first vertical plate or the second vertical plate, and the rotating shaft assembly is connected to the output end of the drive motor.

[0007] In one embodiment, the rotating shaft assembly further includes an L-shaped connecting block, a strip seat connected to the L-shaped connecting block, and a fixing plate slidably disposed within the strip seat, the inner side of the fixing plate including a contact pad.

[0008] In one embodiment, a first support block is provided on the strip-shaped seat, an electric clamping rod is provided on the first support block, and a fixing plate is provided at the output end of the electric clamping rod.

[0009] In one embodiment, a clamping plate is installed at the bottom of the strip plate, a second support block is provided on the lifting plate, a clamping rod is slidably inserted into the second support block, a spring is installed on the second support block and the clamping rod, a clamping hole is opened on the clamping plate, and the clamping rod is inserted into the clamping hole.

[0010] In one embodiment, an electric lifting rod is also included, which is disposed on the base plate and the lifting plate is installed at the output end of the electric lifting rod.

[0011] In one embodiment, the base plate includes multiple mounting positions for electrically operated lifting rods.

[0012] In one embodiment, a positioning rod is installed at the bottom of the strip plate, and a positioning sleeve is installed on the lifting plate, with the positioning rod inserted into the positioning sleeve.

[0014] In one embodiment, a support plate is mounted on the base plate, an electric telescopic rod is disposed on the support plate, and the second vertical plate is connected to the output end of the electric telescopic rod.

[0015] Compared with the prior art, this application has the following beneficial effects: By setting a movable second vertical plate and rotating shaft assemblies located on the first and second vertical plates respectively, the rotating shaft assembly includes a limiting rotating block that mates with a groove on the upper part of the shaft inserted at the end of the coating steel roller. The second vertical plate is moved using an electric telescopic rod, enabling rapid clamping and circumferential positioning of the coating steel roller body. This eliminates the cumbersome bolt tightening or disassembly steps of traditional clamping, simplifying the operation process. Combined with a drive motor, it can stably drive the steel roller to rotate during cleaning, providing a foundation for uniform wiping and improving the overall efficiency of the cleaning operation.

[0016] The rotating shaft assembly further includes an L-shaped connecting block, a strip seat, and a fixed plate that slides within the strip seat driven by an electric clamping rod. The fixed plate has a contact pad on its inner side. The electric clamping rod can drive a pair of fixed plates to move closer to each other and clamp the insert shaft from both sides through the contact pad, thereby enhancing the holding force on the positioned steel roller. This effectively prevents the square block from accidentally coming out of the square groove and improves the stability and safety of the equipment during operation.

[0017] The lifting plate is mounted on the base plate via an electric lifting rod, allowing for height adjustment. The strip plate is positioned by a positioning rod at its bottom engaging with a positioning sleeve on the lifting plate. A snap-fit ​​mechanism, including a clamping plate, spring-loaded clamping rod, and snap-fit ​​holes, enables detachable installation. The electric lifting rod facilitates control of the contact pressure between the cleaning wet wiping strip and the steel roller surface, adapting to different cleaning needs. The engagement of the positioning rod and positioning sleeve ensures alignment during installation, while the snap-fit ​​structure allows for quick assembly and disassembly of the strip plate and cleaning wet wiping strip. This facilitates the replacement or cleaning maintenance of worn parts, reducing downtime.

[0018] In summary, through the synergistic combination of the above-mentioned technical features, the coating steel roller achieves a highly efficient, stable, and easy-to-maintain cleaning function, effectively solving the problems of low cleaning efficiency and inconvenient operation in the existing technology.

[0021] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not the entire structure. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0022] The terms “comprising” and “having”, and any variations thereof, used in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] The following will describe in detail the coating steel roller surface wiping device of this application with reference to the accompanying drawings and specific embodiments. As mentioned above, in the prior art, coating steel rollers are prone to sticking, imprinting, and electrode scratching due to surface stains in the double-layer coating process, and existing cleaning devices suffer from inconvenient disassembly and assembly, and the cleaning efficiency needs to be improved. This application provides an improved solution. To overcome the above-mentioned defects, the device of this application mainly optimizes the clamping drive mechanism of the coating steel roller and the adjustment and fixing method of the cleaning components, aiming to achieve rapid positioning, stable rotation, and efficient wiping of the steel roller. The following embodiments will specifically illustrate the technical structure and cooperative relationship for achieving this objective. Please refer to... Figures 1 to 4 As shown, a preferred embodiment of the coating steel roller surface wiping device of this application includes a base plate 2, a first vertical plate 3, a second vertical plate 4, a lifting plate 9, a strip plate 11, a cleaning wet wiping strip 12, and a rotating shaft assembly 8. The first vertical plate 3 is fixedly disposed on the base plate 2, and the second vertical plate 4 is movably disposed on the base plate 2. The first vertical plate 3 and the second vertical plate 4 are respectively provided with rotating shaft assemblies 8. The rotating shaft assembly 8 includes a limiting rotating block 7, which matches the end insert shaft 5 of the coating steel roller body 1. The rotating shaft assembly 8 on the first vertical plate 3 and the rotating shaft assembly 8 on the second vertical plate 4 are disposed opposite to each other for clamping and driving the coating steel roller body 1 to rotate. The lifting plate 9 is height-adjustable disposed on the base plate 2. The strip plate 11 is detachably mounted on the lifting plate 9, and the cleaning wet wiping strip 12 is disposed on the strip plate 11. The rotating shaft assembly 8 can be partially installed in the first vertical plate 3 and the second vertical plate 4 respectively. The limiting rotating block 7 is used to connect the driving component at the other end. The limiting rotating block 7 can be a square block. The end of the coating steel roller body 1 is equipped with a plug shaft 5. The plug shaft 5 is provided with a slot 6. The slot 6 can be a square groove. The square groove is used to insert the square block.

[0025] Firstly, regarding the cooperative configuration of the base plate 2, the first vertical plate 3, the second vertical plate 4, and the rotating shaft assembly 8, by fixing the first vertical plate 3 to the base plate 2 and movably setting the second vertical plate 4 on the same base plate 2, a structural basis is provided for the rapid clamping and centering of the coating steel roller. The specific clamping and driving functions are achieved by the rotating shaft assembly 8 set on the two vertical plates. The limiting rotating block 7 (specifically a square block) in this assembly is mutually engaged with the slot 6 (specifically a square groove) on the insertion shaft 5 at the end of the coating steel roller body 1. This non-circular cross-section fitting method, such as the interlocking of square blocks and square grooves, can effectively transmit torque, realize the circumferential limiting and driving of the coating steel roller, and avoid the cumbersome operation of traditional bolt fixing methods. The drive motor 10 can be set on the first vertical plate 3 or the second vertical plate 4 and connected to the rotating shaft assembly 8 to provide power for the cleaning rotation of the steel roller. The second vertical plate 4 is preferably driven to move by the electric telescopic rod 28, thereby realizing the rapid tightening and loosening of the coating steel roller, further simplifying the operation process.

[0026] Secondly, the rotating shaft assembly 8 can be further integrated with an axial clamping mechanism to improve operational stability. This mechanism may include an L-shaped connecting block 13, a strip seat 14, a fixing plate 15 driven by an electric clamping rod 18 and slidably disposed within the strip seat 14, and a contact pad 16 fixed to the inner side of the fixing plate 15. After the coating steel roller completes radial positioning through the square block and square groove, the electric clamping rod 18 can drive a pair of fixing plates 15 to approach each other, clamping the end or shoulder of the insert shaft 5 from both sides through the contact pad 16. The contact pad 16 can be made of non-metallic materials with a high coefficient of friction, such as rubber or polyurethane. This effectively increases the clamping friction, preventing the square block from axially dislodging from the square groove due to vibration during the rotation of the steel roller, thus improving the reliability of equipment operation.

[0027] Furthermore, the lifting plate 9, the strip plate 11, and the cleaning wet wiping strip 12 constitute the cleaning execution module of the device. The lifting plate 9 is height-adjustable on the base plate 2 via an electric lifting rod 19, allowing the strip plate 11 and the cleaning wet wiping strip 12 mounted on it to precisely approach or move away from the surface of the coating steel roller. This facilitates adjustment of the contact pressure between the cleaning wet wiping strip 12 and the steel roller to adapt to different cleaning needs or the wear condition of the cleaning wet wiping strip 12. The cleaning wet wiping strip 12 itself can be made of materials such as non-woven fabric or microfiber with good water absorption, softness, and wear resistance, which helps to effectively absorb stains during wiping and reduce potential scratches on the surface of the steel roller.

[0028] Finally, to enable rapid replacement and maintenance of the cleaning components, a detachable quick-clamping structure is adopted between the strip plate 11 and the lifting plate 9. This structure includes a clamping plate 20 at the bottom of the strip plate 11, a second support block 21 on the lifting plate 9, a clamping rod 22 slidably inserted into the second support block 21, and a spring 24 connecting the second support block 21 and the clamping rod 22. The clamping plate 20 has a locking hole 23 that matches the clamping rod 22. During installation, by pressing down on the strip plate 11, the clamping rod 22 compresses the spring 24 and retracts under the action of the inclined surface of the clamping plate 20. When the locking hole 23 moves to align with the clamping rod 22, the spring 24 resets and pushes the clamping rod 22 into the locking hole 23, achieving rapid locking. For disassembly, the strip plate 11 can be removed simply by manually pulling out the clamping rod 22. To further ensure alignment and stability during installation, a positioning rod 25 can be installed at the bottom of the strip plate 11, and a matching positioning sleeve 26 can be installed on the lifting plate 9. The horizontal displacement of the strip plate 11 is limited by the insertion of the positioning rod 25 and the positioning sleeve 26. In addition, level indicators are installed on the base plate 2 and the strip plate 11 to help monitor the level of the equipment during installation and commissioning, and to assist in ensuring uniform contact between the cleaning wet wiping strip 12 and the surface of the steel roller, thereby ensuring the uniformity of the cleaning effect.

[0029] The drive motor 10 can be directly fixed to the outside of the first vertical plate 3 or the second vertical plate 4. Its output shaft passes through the through hole or bearing seat on the vertical plate and is coaxially connected to the rotating shaft assembly 8. Alternatively, a coupling (such as a flange or universal coupling) can be used to connect the output shaft of the drive motor 10 to the rotating shaft assembly 8 to accommodate possible installation alignment errors and facilitate power transmission and component disassembly and assembly. Directly mounting the drive motor 10 on the vertical plate and directly connecting it to the rotating shaft assembly 8 achieves direct drive and stable transmission of the coating steel roller, eliminating the need for complex intermediate transmission mechanisms such as chains and belts. This not only makes the equipment structure more compact and reduces the cumulative errors and potential maintenance points caused by multi-stage transmission, but also reduces noise and vibration during operation. Although this application sets the drive on one side, the support and driven rotation of the rotating shaft assembly 8 on the other vertical plate, along with a stable base, ensures stable operation of the coating steel roller during wiping, minimizing skew. For even higher transmission smoothness, synchronously driven motors can be installed on both vertical plates.

[0030] In the overall structure of the coating steel roller surface wiping device, the rotating shaft assembly 8 integrates a specific clamping mechanism. This assembly also includes an L-shaped connecting block 13 fixedly sleeved with the drive shaft, a strip seat 14 connected to the L-shaped connecting block 13, a fixing plate 15 slidably disposed within the strip seat 14, and a contact pad 16 installed on the inner side of the fixing plate 15. The L-shaped connecting block 13 is fixed to the extended end of the drive shaft, with its horizontal section connected to the drive shaft and its vertical section used to connect the strip seat 14, providing additional mounting surface and support. For example, in a connecting plate with adjustable mounting position, the L-shaped connecting plate is used to fix components on the side plate and maintain a horizontal state. The strip seat 14 is fixedly installed on the vertical section of the L-shaped connecting block 13, and its interior is provided with a sliding groove or guide rail. The fixing plate 15 is slidably installed within the strip seat 14 through the sliding groove or guide rail, so that the fixing plate 15 can stably reciprocate in a specific direction. To drive the sliding of the fixed plate 15, a first support block 17 is installed on the strip seat 14, and an electric clamping rod 18 is set on the first support block 17, with its output end connected to the fixed plate 15. The opening and closing of a pair of fixed plates 15 can be controlled by the extension and retraction movement of the electric clamping rod 18.

[0031] On the inner side of the fixing plate 15, i.e., the side facing the coating steel roller insert shaft 5, a contact pad 16 is installed, which is directly responsible for contacting the end or shoulder surface of the insert shaft 5. The contact pad 16 can be made of elastic non-metallic materials with a high coefficient of friction, such as rubber or polyurethane. In this application, the contact pad 16 utilizes the slight elastic deformation of the material to adapt to the slight unevenness of the insert shaft 5 surface, thereby enhancing the tightness of the clamping and avoiding surface damage that may be caused by direct contact between metal parts.

[0032] The combination of the L-shaped connecting block 13, the strip-shaped seat 14, the sliding fixing plate 15, and the contact pad 16 serves to provide auxiliary axial clamping for the coating steel roller. After the insertion shaft 5 at the end of the coating steel roller is inserted into the square block on the drive shaft via its square groove, achieving radial limiting and torque transmission, the electric clamping rod 18 drives a pair of fixing plates 15 to move closer together, securely clamping the insertion shaft 5 from both sides via the contact pad 16. This provides a second constraint besides the square block and square groove engagement, effectively preventing the coating steel roller from axially shifting or even detaching during high-speed rotation or vibration, thus improving the stability and safety of the equipment operation. Furthermore, compared to traditional bolt locking methods, this clamping mechanism achieves rapid opening and closing via electric drive, simplifying the assembly and disassembly steps and contributing to improved overall cleaning efficiency.

[0033] In the overall configuration of the coating steel roller surface wiping device, the rotating shaft assembly 8, through the integration of a specific clamping mechanism, can improve the connection stability and operational automation level of the coating steel roller during cleaning operations. Specifically, this assembly has a first support block 17 on the strip seat 14, an electric clamping rod 18 is mounted on the first support block 17, and a fixing plate 15 is mounted on the output end of the electric clamping rod 18. Through the combination of the first support block 17, the electric clamping rod 18, and the fixing plate 15, its core function is to achieve automated axial clamping and loosening of the coating steel roller insert shaft 5. When the insertion shaft 5 at the end of the coating steel roller is inserted into the square block on the drive shaft through the square groove on it, and radial limiting and torque transmission are achieved, the electric clamping rod 18 can drive a pair of fixing plates 15 to move closer to each other, and firmly clamp the insertion shaft 5 from both sides through the contact pad 16, providing a second constraint in addition to the cooperation between the square block and the square groove. This can effectively prevent the coating steel roller from axially moving or even detaching when rotating or vibrating, and improve the stability and safety of the equipment operation.

[0034] In the overall configuration of the wiping device for the surface of the coating steel roller, a specific detachable connection structure is adopted between the strip plate 11 and the lifting plate 9 to achieve rapid replacement and stable fixation of the cleaning wet wiping strip 12. Specifically, this structure includes a clamping plate 20 installed at the bottom of the strip plate 11, a second support block 21 set on the lifting plate 9, a clamping rod 22 slidably inserted into the second support block 21, a spring 24 connecting the second support block 21 and the clamping rod 22, and a clamping hole 23 opened on the clamping plate 20. The clamping rod 22 can be inserted into the clamping hole 23 under the action of the spring 24. The clamping plate 20 is fixedly installed at the bottom of the strip plate 11. As the base component for connection, it is usually designed as a metal plate with a certain thickness to provide sufficient structural strength. The diameter of the clamping hole 23 opened on the clamping plate 20 matches the diameter of the clamping rod 22. The edge of the clamping hole 23 can be chamfered to facilitate the smooth insertion of the clamping rod 22. The second support block 21 is fixedly installed on the lifting plate 9. Its interior has a sliding channel or bearing that matches the locking rod 22, ensuring that the locking rod 22 can smoothly reciprocate in a predetermined direction. The second support block 21 provides a stable mounting base for the entire locking mechanism. The locking rod 22, acting as a locking pin, slides through the sliding channel of the second support block 21. One end is designed as a locking end that can be inserted into the locking hole 23. This locking end can be made conical or hemispherical to assist in guidance, while the other end can be equipped with a pull ring or handle for easy manual operation. Spring 24 is sleeved on latch 22, or its restoring force is applied to latch 22 in other ways, causing it to tend to move toward latch plate 20. Spring 24 is usually a compression spring 24, and its preload must be sufficient to keep latch 22 and latch hole 23 reliably engaged in the working state of the device to prevent accidental loosening due to vibration. At the same time, its force value must be controlled so that the operator can unlock the latch 22 by manually pulling it against the force of spring 24 without the aid of tools.

[0035] During installation, align the locking plate 20 at the bottom of the strip plate 11 with the corresponding position on the lifting plate 9 and press it down. The locking plate 20 contacts the inclined surface or end of the locking rod 22, forcing the locking rod 22 to compress the spring 24 and retract into the second support block 21. When the locking plate 20 moves to the position where the locking hole 23 aligns with the locking rod 22, the elastic potential energy stored in the spring 24 is released, pushing the locking rod 22 to quickly insert into the locking hole 23, thus completing the installation and locking of the strip plate 11. This process requires no tools, achieving rapid positioning and automatic locking. During disassembly, the operator only needs to manually pull the locking rod 22 in the direction of disengagement from the locking hole 23, overcoming the force of the spring 24 to remove the locking rod 22 from the locking hole 23, so that the strip plate 11 can be removed together with the cleaning wet wiping strip 12, thereby facilitating the replacement or cleaning and maintenance of the worn cleaning wet wiping strip 12.

[0036] In the overall configuration of the coating steel roller surface wiping device, the precise adjustment of the contact pressure between the cleaning component and the steel roller surface is crucial for achieving effective cleaning. Therefore, this application provides an electric lifting rod 19 on the base plate 2, and the lifting plate 9 is installed at the output end of the electric lifting rod 19. The electric lifting rod 19, as the core driving element, has its cylinder body fixedly installed on the base plate 2. The electric lifting rod 19 can be in the form of an electric push rod, a screw mechanism driven by a servo motor, or a pneumatically driven cylinder. In this application, the output end of the electric lifting rod 19 is directly connected to the lifting plate 9. By controlling the extension and retraction of the electric lifting rod 19, the vertical position of the lifting plate 9 can be precisely controlled. The lifting plate 9 serves as the mounting base for the cleaning module, and its levelness significantly affects the uniformity of the cleaning effect. To ensure the stability of the lifting plate 9 during the lifting process and prevent skewing or shaking, an auxiliary guiding mechanism can also be provided. In this device, a similar mechanism combining a guide rod and a linear bearing, or a combination of a guide rail and a slider, can also be used to ensure that the lifting plate 9 moves smoothly along a predetermined trajectory.

[0037] The configuration of the lifting plate 9 driven by the electric lifting rod 19 is primarily designed to precisely control and conveniently adjust the contact pressure between the cleaning wet wiping strip 12 and the surface of the coating steel roller. By controlling the extension of the electric lifting rod 19, the lifting plate 9 and its strip plate 11, along with the cleaning wet wiping strip 12, are driven to rise together until the cleaning wet wiping strip 12 contacts the surface of the coating steel roller body 1 with appropriate pressure. The adjustable contact pressure ensures sufficient contact between the cleaning wet wiping strip 12 and the roller surface for effective stain removal. Furthermore, it avoids excessive wear of the cleaning wet wiping strip 12, made of flexible materials such as non-woven fabric or microfiber, or potential damage to the steel roller surface due to excessive pressure. Compared to manual screw lifting and other adjustment methods, electric lifting offers higher control precision and automation.

[0038] In the overall configuration of the coating steel roller surface wiping device, multiple electric lifting rod 19 mounting positions are provided on the base plate 2 to achieve stable support and adaptive adjustment of the cleaning components under different working conditions. The arrangement of the multiple electric lifting rod 19 mounting positions on the base plate 2 can be designed according to the requirements of support stability and load distribution. The core function of setting multiple electric lifting rod 19 mounting positions on the base plate 2 is to improve the adaptability and versatility of the wiping device for different cleaning tasks and subsequent possible product variations. Specifically, this design allows for a certain degree of selectivity in the mounting positions of the electric lifting rod 19 on the base plate 2. When processing coating steel rollers of different lengths or weights, or when it is necessary to replace cleaning components of different specifications (such as longer or heavier ones) (e.g., strip plate 11 and cleaning wet wiping strip 12), the requirements for the load and stability of the lifting plate 9 and its drive mechanism may change. By selecting different installation positions to fix the electric lifting rod 19, the spacing of the support points can be adjusted. This allows for the stability of the lifting plate 9 during the lifting process when dealing with larger loads or wide cleaning components by increasing the number of support points or optimizing the support distribution. It also helps maintain the uniformity of the contact pressure between the cleaning wet wiping strip 12 and the surface of the coating steel roller body 1.

[0039] In the overall configuration of the coating steel roller surface wiping device, to achieve efficient maintenance and stable operation of the cleaning wet wiping strip 12, a specific quick-release and precise positioning structure is provided between the strip plate 11 and the lifting plate 9. Following the aforementioned snap-fit ​​mechanism, the positioning rod 25 installed at the bottom of the strip plate 11 and the positioning sleeve 26 installed on the lifting plate 9 engage in a plug-in fit, further improving the centering and stability during installation. The positioning rod 25 is fixedly installed at the bottom of the strip plate 11 and is typically made of a rigid metal round rod, with its end designed as a guide cone or chamfer. The positioning sleeve 26 is fixedly installed at the corresponding position on the lifting plate 9, with its inner diameter forming a precise clearance fit with the diameter of the positioning rod 25 to ensure smooth insertion of the positioning rod 25 without significant wobble. The height of the positioning sleeve 26 needs to provide sufficient guide stroke, and its inner wall can be lubricated or surface-treated to reduce wear.

[0040] The core function of the insertion and engagement of the positioning rod 25 and the positioning sleeve 26 is to provide preliminary coarse positioning and precise guidance for the installation of the strip plate 11 and the cleaning wet wiping strip 12. During installation, the positioning rod 25 at the bottom of the strip plate 11 is aligned with the positioning sleeve 26 on the lifting plate 9 and inserted. This action can pre-correct the horizontal position of the strip plate 11 before the subsequent snap-fit ​​structure (such as the snap-fit ​​rod 22 and the snap-fit ​​hole 23) takes effect, effectively limiting its movement and rotation in the horizontal plane. This pre-positioning and guidance can improve the success rate and accuracy of the subsequent snap-fit ​​action, ensuring that the snap-fit ​​rod 22 can be aligned and snapped into the snap-fit ​​hole 23 without deviation, thereby achieving fast and error-free installation. In the working state, the cleaning wet wiping strip 12 contacts the surface of the high-speed rotating coating steel roller and bears a certain frictional reaction force. At this time, the tight engagement of the positioning rod 25 and the positioning sleeve 26, together with the snap-fit ​​mechanism, constitutes a double guarantee to prevent horizontal displacement and rotation of the strip plate 11, enhancing the anti-eccentric load capacity and overall stability of the cleaning module in the working state. It helps maintain the uniformity of the contact area between the cleaning wet wiping strip 12 and the steel roller surface. The clear positioning reference makes it easy to find the correct installation position when replacing the strip plate 11 and the cleaning wet wiping strip 12, which simplifies the operation process and reduces the time spent on repeated adjustments due to misalignment.

[0041] In the overall configuration of the coating steel roller surface wiping device, monitoring and adjusting the horizontal status of key components is an important auxiliary measure to ensure the stability of the cleaning process and the uniformity of the wiping effect. Therefore, this application provides horizontal indicators on the base plate 2 and the strip plate 11. The horizontal indicators can be conventional bubble levels, and their installation methods include, but are not limited to, fixing them to specific positions on the base plate 2 and the strip plate 11 by embedding or screwing. To ensure accurate reflection of the horizontal status of the basic frame and the cleaning execution components, the horizontal indicators should be installed on a machined flat reference surface. On the base plate 2, the horizontal indicators are typically located near the edge and in easily observable locations, such as the four corners or the center of the long side of the base plate 2, to monitor the reference level of the entire device. On the strip plate 11, the horizontal indicators are preferably installed near its connection structure with the lifting plate 9. The core function of providing horizontal indicators on the base plate 2 and the strip plate 11 is to provide an intuitive visual reference for the installation, debugging, and status monitoring of the wiping device, thereby indirectly ensuring the uniformity of the cleaning effect. Specifically, during initial equipment installation or workstation changes, the level indicator on the base plate 2 can be used to adjust the anchor bolts or other leveling mechanisms located below the base plate 2 to ensure the entire foundation frame is level. This helps ensure the correct alignment of subsequent components such as vertical plates and drive shafts, reducing additional stress or running resistance caused by uneven foundations. The level indicator on the strip plate 11 directly reflects the posture of the mounting base of the cleaning wet wiping strip 12. By observing its display and combining it with the adjustment function of the lifting plate 9, the strip plate 11 and the cleaning wet wiping strip 12 can be kept as level as possible, helping to achieve uniform axial contact between the cleaning wet wiping strip 12 and the surface of the rotating coating steel roller body 1. If the strip plate 11 is tilted, it may cause uneven contact pressure between the cleaning wet wiping strip 12 and the steel roller surface. Some areas may have excessive pressure, accelerating wear, while other areas may have insufficient pressure, resulting in incomplete cleaning. Therefore, using the level indicator for leveling is a fundamental and effective measure to ensure a consistent cleaning effect across the entire roller surface. In addition, during long-term operation, the level indicator can also be used as a quick daily inspection tool. If a change in the level is found, it may indicate abnormal deformation, which facilitates timely maintenance.

[0042] In the overall configuration of the coating steel roller surface wiping device, a support plate 27 is installed on the base plate 2, and an electric telescopic rod 28 is set on the support plate 27. The movable second vertical plate 4 (or sliding plate) is connected to the output end of the electric telescopic rod 28. The support plate 27 serves as a load-bearing and support structure. Its bottom is fixed to the base plate 2 by welding or bolting, providing a stable mounting base for the electric telescopic rod 28 that is perpendicular to the base plate 2 and has a certain height. The number and layout of the support plates 27 can be set according to the size of the second vertical plate 4 and the required pushing force. For example, two sets of support plates 27 and electric telescopic rods 28 can be symmetrically arranged on both sides of the width direction of the second vertical plate 4 to ensure the balanced transmission of the pushing force.

[0043] The electric telescopic rod 28 serves as the driving element, with its cylinder body fixed to the support plate 27 via a flange or hinge. The electric telescopic rod 28 can be in the form of an electric push rod, a ball screw mechanism driven by a servo motor, or a pneumatically driven cylinder. The second vertical plate 4 serves as a movable support unit, and its bottom is typically equipped with a slider or linear bearing, forming a sliding pair with a corresponding guide rail or optical shaft fixed to the base plate 2. This ensures that it can move smoothly along a predetermined linear trajectory under the drive of the electric telescopic rod 28, without deflection or jamming.

[0044] The configuration of the second vertical plate 4, driven by the support plate 27 and the electric telescopic rod 28, enables automated axial clamping and loosening of the coating steel roller, ensuring the stability of the drive connection. Specifically, when installing the coating steel roller, the operator first aligns one end of the coating steel roller (e.g., the end with the fixed insertion shaft 5) with the rotating shaft assembly 8 (e.g., a square block and a square groove) on the fixed side of the first vertical plate 3. Then, the electric telescopic rod 28 is activated, extending its output shaft and pushing the second vertical plate 4 towards the coating steel roller, so that the limiting rotating block 7 (e.g., a square block) of the rotating shaft assembly 8 on the second vertical plate 4 is precisely inserted into the slot 6 (e.g., a square groove) on the insertion shaft 5 at the other end of the coating steel roller. After cleaning, the electric telescopic rod 28 retracts, driving the second vertical plate 4 to remove the square block from the square groove of the insertion shaft 5, thereby quickly releasing the constraint on one end of the coating steel roller and facilitating its removal. The quick assembly and disassembly mechanism is particularly suitable for production scenarios that require frequent replacement or maintenance of coating steel rollers, helping to reduce equipment downtime.

[0045] As described above, this application provides a surface wiping device for coating steel rollers. This device achieves rapid clamping, stable driving, and efficient cleaning of the coating steel rollers through an optimized mechanical structure. Regarding the clamping and driving of the steel rollers, the device includes a base plate, a fixed first vertical plate, and a movable second vertical plate. The second vertical plate is driven axially by a support plate on the base plate and an electric telescopic rod. Rotary shaft assemblies are respectively provided on the first and second vertical plates. The limiting rotating block of this assembly is interlocked with the slot of the end shaft of the coating steel roller, for example, a square block and square slot can be used to achieve circumferential limiting and torque transmission of the coating steel roller. A drive motor is mounted on the vertical plate and connected to the rotary shaft assembly, providing rotational power for cleaning the steel roller. To further enhance connection stability, the rotary shaft assembly can also integrate an axial clamping mechanism, which includes an L-shaped connecting block, a strip seat, a fixed plate driven by an electric clamping rod and slidably disposed within the strip seat, and a contact pad disposed on the inner side of the fixed plate. After the square block and square slot are inserted, the electric clamping rod can drive the fixing plate to clamp the insertion shaft from both sides through the contact pad, forming an auxiliary axial constraint to prevent the steel roller from axially shifting or detaching during rotation.

[0046] In terms of cleaning execution, the device features a lifting plate driven by an electric lifting rod and adjustable in height on the base plate. The strip plate is detachably mounted on the lifting plate via a quick-clamping structure, which includes a locking plate at the bottom of the strip plate, a second support block on the lifting plate, a locking rod slidably inserted into the second support block, and a spring connecting the two. The locking plate has locking holes for the locking rod to insert, enabling quick locking and releasing of the strip plate. To further improve installation alignment and operational stability, a positioning rod can be installed at the bottom of the strip plate, engaging with a positioning sleeve on the lifting plate. The cleaning wet wiping strip is mounted on the strip plate and can be made of materials such as non-woven fabric or microfiber. Adjusting the height of the lifting plate via the electric lifting rod controls the contact pressure between the cleaning wet wiping strip and the steel roller surface. To ensure uniform cleaning results, level indicators can be installed on the base plate and the strip plate to assist in monitoring and adjusting the device's level.

[0047] In summary, through the coordinated operation of the aforementioned mechanisms, this application achieves rapid clamping and disassembly of the coating steel roller, stable rotation drive, convenient adjustment of cleaning contact pressure, and rapid replacement of cleaning components, thereby improving the cleaning efficiency and ease of operation of the steel roller surface.

[0048] The above is only one specific implementation of this application, and any other improvements made based on the concept of this application shall be considered within the scope of protection of this application.
