Description

Technical Field

[0001] This utility model relates to the field of cold-rolled steel sheet cleaning technology, specifically to a high-efficiency steel sheet wiper. Background Technology

[0002] 400 series stainless steel BA sheet (mirror finish) is commonly used in elevator interior decoration and other fields, requiring a surface free of scratches, flaws and with a bright finish.

[0003] To meet the surface quality requirements of mirror-finish panels, the cold rolling process uses pure oil rolling. This process has the advantage of producing a bright strip surface, but it also has significant drawbacks. Because oil has a lower specific heat capacity than water, its ability to remove heat is weaker. To meet the plate temperature requirements, the amount of oil used during the rolling process is greater than when using emulsions.

[0004] Ordinary strip wipers cannot effectively remove oil from the surface of strip steel. Residual oil can easily cause the steel coil to slip, limiting the increase in rolling speed and thus affecting production capacity. A large amount of oil is carried away, resulting in a significant increase in production costs.

[0005] Existing degreasing methods involve first using four steel rollers for initial oil scraping, followed by a second oil scraping with a pressure cloth. This method suffers from incomplete oil removal, and dirt can easily remain on the pressure cloth, potentially scratching the strip surface and affecting its quality. Therefore, this application provides a high-efficiency strip wiper. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a high-efficiency strip wiper, which solves the problem that in the above-mentioned existing technologies, when using steel rollers for degreasing, the degreasing is not thorough and is prone to causing damage to the surface of the strip steel.

[0007] The high-efficiency strip wiper of this utility model includes:

[0008] A scraping assembly comprising at least two scrapers, which are mirror-symmetrically disposed on both sides of the cold-rolled sheet, with the side of the two scrapers closest to each other in contact with the surface of the cold-rolled sheet.

[0009] The scraper has a contact angle set at a preset angle on the side near the cold-rolled plate. A friction block is provided on the inner side of the contact angle. One side of the friction block is inclined at a preset angle and contacts the surface of the cold-rolled plate.

[0010] A twin-roller conveyor assembly is provided on one side of a scraping assembly, and a multi-roller assembly is provided on the other side of the twin-roller conveyor assembly for cleaning cold-rolled steel sheets.

[0011] A fixed distance is maintained between the twin-roller conveyor assembly and the double-roller conveyor assembly, and a support assembly is installed thereon. A cleaning assembly is provided below the support assembly for cleaning the surface of the cold-rolled sheet.

[0012] An air-blowing assembly is provided on one side of the multi-roll assembly. The air-blowing assembly is located on both sides of the cold-rolled sheet and is used to clean and dry the cold-rolled sheet.

[0013] As a further improvement of this utility model, the double roller conveyor assembly includes symmetrically arranged side plates, a fixing frame is provided between the two side plates, a positioning roller is installed on the inner side of the fixing frame, and two degreasing rollers with a fixed spacing are provided below the positioning rollers for cleaning the surface of the cold-rolled plate.

[0014] As a further improvement of this utility model, the two ends of the positioning roller are set in the grooves opened in the side plate, the top of the side plate is provided with a locking block, the top of the locking block is provided with an adjusting rod, one end of the adjusting rod is provided with a lead screw, and the lead screw is connected to one end of the positioning roller for controlling the positioning roller to perform reciprocating linear motion.

[0015] As a further improvement of this utility model, a guide roller is provided between the two degreasing rollers. The guide roller is located below the positioning roller and is used to guide the cold-rolled sheet.

[0016] As a further improvement of this utility model, a base is provided at the bottom of the two side plates, and baffles are provided on both sides of the base outside the degreasing roller. The baffles are spaced at a fixed distance from the positioning roller to form a passage area for the passage of the cold-rolled plate.

[0017] As a further improvement of this utility model, one end of the two oil removal rollers is provided with a pulley on one side of the side plate, and a belt is sleeved on the outside of the pulley. A drive shaft is provided in the middle of one of the oil removal rollers, and a drive component is installed on the drive shaft to drive the two oil removal rollers to rotate.

[0018] As a further improvement of this utility model, the cleaning component includes a mounting frame, and a fixed shaft is provided on the inner side of the mounting frame at uniform intervals. A coating block and a cleaning block are installed at the fixed shaft, and the side of the coating block and the cleaning block that contacts the cold-rolled plate is flat.

[0019] As a further improvement of this utility model, the top and bottom of the mounting frame are provided with support components. The support components include telescopic members, and one end of the piston rod of the telescopic member is provided with a support block for supporting the mounting frame.

[0020] As a further improvement of this utility model, the air blowing assembly includes a connecting frame, which is fixed to one end of the multi-roller assembly.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] This invention uses a scraper and friction block in the scraping assembly to make close contact with the surface of the cold-rolled sheet. The scraper can quickly scrape off most of the oil stains on the surface of the cold-rolled sheet, while the friction block further rubs and cleans the surface after the scraper has removed the oil stains and impurities. By adopting a dual scraping and cleaning method, the efficiency of oil stain removal is greatly improved. Compared with the traditional single scraping method, more oil stains can be removed in a shorter time, which reduces the burden on subsequent cleaning steps.

[0024] Meanwhile, through the coordinated operation of the scraping component, the twin-roller conveyor component, the cleaning component, and the air blowing component, multi-stage cleaning and treatment of the surface of the cold-rolled sheet is achieved. Furthermore, the adjustable structures in each component, such as the telescopic component of the scraping component, the adjusting rod of the twin-roller conveyor component, and the support component of the cleaning component, enable the equipment to adapt to cold-rolled sheets of different thicknesses, materials, and surface conditions, thereby enhancing the equipment's versatility and applicability and meeting diverse needs.

However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0042] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0043] For decorative mirror-finish stainless steel 400 series BA sheets, the surface quality requirements are extremely stringent, demanding a high gloss finish free of scratches and imperfections. While pure oil rolling is used in cold rolling processes to meet these high surface quality requirements, this process presents several problems that existing degreasing methods struggle to effectively address, negatively impacting production capacity and costs. Therefore, please refer to [further details needed]. Figure 1 , Figure 2 , Figure 7 as well as Figure 3 This application provides a high-efficiency strip wiper, comprising:

[0044] The scraping component 2 includes at least two scraper blades 21, which are mirror-symmetrically arranged on both sides of the cold-rolled sheet 1. The side of the two scraper blades 21 that are close to each other is in contact with the surface of the cold-rolled sheet 1.

[0045] The scraper 21 is provided with a contact angle 24 at a preset angle on the side near the cold-rolled plate 1. A friction block 23 is provided on the inner side of the contact angle 24. One side of the friction block 23 is inclined at a preset angle and contacts the surface of the cold-rolled plate 1.

[0046] A double-roller conveyor assembly 3 is disposed on one side of the scraping assembly 2, and a multi-roller assembly 5 is disposed on the other side of the double-roller conveyor assembly 3 for cleaning the cold-rolled sheet 1.

[0047] The twin-roller conveyor assembly 3 and the double-roller conveyor assembly maintain a fixed distance and are equipped with a support assembly 4. A cleaning assembly 7 is provided below the support assembly 4 for cleaning the surface of the cold-rolled sheet 1.

[0048] An air blowing assembly 6 is provided on one side of the multi-roll assembly 5. The air blowing assembly 6 is located on both sides of the cold-rolled plate 1 and is used to clean and dry the cold-rolled plate 1.

[0049] The scraping assembly 2 includes at least two scrapers 21, which are mirror-symmetrically arranged on both sides of the cold-rolled sheet 1. The symmetrical arrangement of the scrapers 21 ensures that the oil stains on both sides of the cold-rolled sheet 1 can be effectively scraped off. The side of the two scrapers 21 that is close to each other is in contact with the surface of the cold-rolled sheet 1. When the cold-rolled sheet 1 passes through the scrapers 21 during the rolling process, the scrapers 21 can directly perform preliminary scraping of the oil stains on the surface of the cold-rolled sheet 1.

[0050] The contact angle 24 allows the scraper 21 to contact the surface of the cold-rolled sheet 1 at the optimal angle, improving the oil removal effect. A friction block 23 is provided inside the contact angle 24, with one side of the friction block 23 inclined at a preset angle and in contact with the surface of the cold-rolled sheet 1. The function of the friction block 23 is to further enhance the oil removal ability based on the oil removal by the scraper 21. Because the contact area between the friction block 23 and the surface of the cold-rolled sheet 1 is small, a large frictional force is generated during contact, which can more effectively scrape off stubborn oil adhering to the surface of the cold-rolled sheet 1. To ensure the smoothness of the cold-rolled sheet 1, the end of the friction block 23 in contact with the cold-rolled sheet 1 is generally made of a pure cotton cleaning cloth.

[0051] To avoid scratching the surface of the cold-rolled sheet 1 at the contact angle 24, a rubber strip can be fitted on the contact angle 24;

[0052] The twin-roll conveyor assembly 3 is located on one side of the scraping assembly 2. Its main function is to convey the cold-rolled sheet 1 after its preliminary treatment by the scraping assembly 2, ensuring that the cold-rolled sheet 1 can smoothly enter the subsequent processing stages. The twin-roll conveyor assembly 3 consists of two rollers, the surfaces of which are specially treated to have a certain degree of friction, ensuring that the cold-rolled sheet 1 does not slip during conveying. Simultaneously, the rotational speed of the twin-roll conveyor assembly 3 can be adjusted according to the actual rolling speed to match the overall production process.

[0053] A multi-roller assembly 5 is located on the other side of the twin-roller conveyor assembly 3 and is used for further cleaning of the cold-rolled sheet 1. The multi-roller assembly 5 typically consists of multiple rollers, the arrangement of which and their surface materials can be designed according to different cleaning requirements. For example, the roller surfaces can be made of absorbent materials, such as sponges or special fibers, capable of absorbing residual oil and impurities on the surface of the cold-rolled sheet 1. As the cold-rolled sheet 1 passes through the multi-roller assembly 5, the multiple rollers wipe and clean the surface of the cold-rolled sheet 1 from different angles and positions, further improving the cleaning effect.

[0054] A fixed distance is maintained between the twin-roller conveyor assembly 3 and the multi-roller assembly 5, and a support assembly 4 is installed thereon. The function of the support assembly 4 is to ensure that the cold-rolled sheet 1 remains stable during the conveying process from the twin-roller conveyor assembly 3 to the multi-roller assembly 5, preventing swaying or deformation. The support assembly 4 can take various forms, such as a support frame or support plate, and its material can be a high-strength metal to ensure sufficient support strength.

[0055] A cleaning component 7 is provided below the support component 4 for cleaning the surface of the cold-rolled sheet 1. The cleaning component 7 can take the form of a spray device or a wiping device. For example, the spray device can spray cleaning liquid onto the surface of the cold-rolled sheet 1 to dissolve and clean residual oil stains; the wiping device can use a soft wiping cloth or brush to further wipe the surface of the cold-rolled sheet 1 to ensure that oil stains and impurities are thoroughly removed.

[0056] An air-blowing assembly 6 is provided on one side of the multi-roll assembly 5, and the air-blowing assembly 6 is located on both sides of the cold-rolled sheet 1. The function of the air-blowing assembly 6 is to clean and dry the cold-rolled sheet 1 after it has been processed by the multi-roll assembly 5 and the cleaning assembly 7. The air-blowing assembly 6 blows high-pressure gas onto the surface of the cold-rolled sheet 1 to dry any residual cleaning liquid and moisture, and also blows away some small impurities, ensuring that the surface of the cold-rolled sheet 1 is dry and clean, meeting the final quality requirements. The air-blowing assembly 6 can use compressed air or nitrogen, and the gas pressure and flow rate can be adjusted according to actual conditions.

[0057] Working principle

[0058] During the rolling process of cold-rolled sheet 1, it first passes through scraping assembly 2, where scraper 21 and friction block 23 initially remove a large amount of oil stains from the surface of cold-rolled sheet 1. Then, cold-rolled sheet 1 is smoothly conveyed to multi-roll assembly 5 via twin-roll conveyor assembly 3, where multi-roll assembly 5 further cleans the cold-rolled sheet 1. During the conveying process, support assembly 4 ensures the stability of cold-rolled sheet 1, and cleaning assembly 7 performs additional cleaning treatment on the surface of cold-rolled sheet 1. Finally, air blowing assembly 6 dries and cleans cold-rolled sheet 1, removing residual cleaning liquid and minor impurities, so that the surface of cold-rolled sheet 1 meets the quality standard of being free of oil stains, scratches, and defects, and has a bright finish.

[0059] The design and use of this high-efficiency strip wiper can effectively solve the problems of existing degreasing methods, improve degreasing efficiency and effect, avoid scratching the strip surface, increase production capacity, reduce costs, and ensure that the quality of the strip meets market demands.

[0060] Please see Figure 4 , Figure 5 as well as Figure 6 The double-roller conveyor assembly 3 includes symmetrically arranged side plates 39, a fixing frame 310 is provided between the two side plates 39, a positioning roller 31 is installed on the inner side of the fixing frame 310, and two degreasing rollers 38 with a fixed spacing are provided below the positioning roller 31 for cleaning the surface of the cold-rolled plate 1.

[0061] The two ends of the positioning roller 31 are set in the grooves opened in the side plate 39. The top of the side plate 39 is provided with a locking block 312. The top of the locking block 312 is provided with an adjusting rod 32. One end of the adjusting rod 32 is provided with a lead screw 311. The lead screw 311 is connected to one end of the positioning roller 31 and is used to control the positioning roller 31 to perform reciprocating linear motion.

[0062] A guide roller 313 is provided between the two degreasing rollers 38. The guide roller 313 is located below the positioning roller 31 and is used to guide the cold-rolled sheet 1.

[0063] The bottom of the two side plates 39 is provided with a base 36, and baffles 37 are provided on both sides of the base 36 outside the degreasing roller 38. The baffles 37 are at a fixed distance from the positioning roller 31 to form a passage area for the passage of the cold-rolled plate 1.

[0064] One end of each of the two degreasing rollers 38 is provided with a pulley 33 on one side of the side plate 39. A belt 35 is sleeved on the outside of the pulley 33. A drive shaft 34 is provided in the middle of one of the degreasing rollers 38. A drive component is installed on the drive shaft 34 to drive the two degreasing rollers 38 to rotate.

[0065] The twin-roller conveyor assembly 3 includes symmetrically arranged side plates 39, which are parallel and opposite to each other, providing basic frame support for the entire assembly. A fixing frame 310 is provided between the two side plates 39. The fixing frame 310 is usually made of high-strength metal material, and its function is to fix components such as the positioning roller 31 and the degreasing roller 38 in a proper position to ensure that they do not shake or shift during operation.

[0066] A positioning roller 31 is installed on the inner side of the fixed frame 310. The two ends of the positioning roller 31 are set in the grooves opened in the side plate 39, so that the positioning roller 31 can move within a certain range in the grooves, and at the same time ensure its stability during the movement.

[0067] A locking block 312 is provided on the top of the side plate 39, which serves to fix and support the adjusting rod 32. The adjusting rod 32 is located on the top of the locking block 312, and a lead screw 311 is attached to one end of the adjusting rod 32. The lead screw 311 is connected to one end of the positioning roller 31. By rotating the adjusting rod 32, the lead screw 311 can drive the positioning roller 31 to perform reciprocating linear motion. The advantage of this adjustment method is that the distance between the positioning roller 31 and the cold-rolled plate 1 can be flexibly adjusted according to the thickness of the cold-rolled plate 1 and the actual cleaning requirements, ensuring that the positioning roller 31 can accurately position and assist in cleaning the cold-rolled plate 1. For example, when the cold-rolled plate 1 is thicker, the positioning roller 31 can be moved upward a certain distance using the adjusting rod 32; when the cold-rolled plate 1 is thinner, the positioning roller 31 can be moved downward to better fit the surface of the cold-rolled plate 1.

[0068] Below the positioning roller 31 are two degreasing rollers 38 that maintain a fixed distance. The surfaces of these two degreasing rollers 38 are typically made of materials with good adsorption and cleaning capabilities, such as special rubber or fiber materials. When the cold-rolled sheet 1 passes between the two degreasing rollers 38, the degreasing rollers 38 can further clean the upper and lower surfaces of the cold-rolled sheet 1, removing residual oil and impurities.

[0069] A guide roller 313 is disposed between the two degreasing rollers 38, and the guide roller 313 is located below the positioning roller 31. The main function of the guide roller 313 is to guide the cold-rolled sheet 1, ensuring that the cold-rolled sheet 1 can accurately pass through the double-roller conveyor assembly 3, avoiding deviation or jamming. The surface of the guide roller 313 is smooth, which can reduce the friction between it and the cold-rolled sheet 1, making the conveying of the cold-rolled sheet 1 smoother.

[0070] The bottom of each of the two side plates 39 is provided with a base 36, which is usually made of heavy metal material and has good stability and load-bearing capacity. The function of the base 36 is to support the entire twin-roller conveyor assembly 3, so that it can be stably installed on the production line.

[0071] Baffles 37 are provided on both sides of the base 36 outside the degreasing roller 38. The baffles 37 are spaced at a fixed distance from the positioning roller 31 to form a passage area for the passage of the cold-rolled sheet 1. The function of the baffles 37 is to prevent oil and impurities from splashing into the surrounding environment during the cleaning process, and also to protect the cold-rolled sheet 1 from external interference during the conveying process.

[0072] One end of each of the two degreasing rollers 38 is equipped with a pulley 33 on one side of the side plate 39, and a belt 35 is fitted around the outside of the pulley 33. A drive shaft 34 is located in the middle of one of the degreasing rollers 38, and a drive component, typically a motor, is mounted on the drive shaft 34. When the drive component is activated, it drives one of the degreasing rollers 38 to rotate via the drive shaft 34. The pulley 33 on this degreasing roller 38 then drives the other degreasing roller 38 to rotate synchronously via the belt. This belt drive method has the advantages of simple structure and smooth transmission, ensuring that the two degreasing rollers 38 rotate at the same speed and direction, thereby effectively cleaning the surface of the cold-rolled sheet 1.

[0073] When the cold-rolled sheet 1, after preliminary treatment by the scraping assembly 2, enters the twin-roll conveyor assembly 3, it is first positioned by the positioning roller 31 to ensure accurate entry into the passage area. Then, guided by the guide roller 313, the cold-rolled sheet 1 smoothly passes between two degreasing rollers 38. At this time, the drive unit drives the degreasing rollers 38 to rotate, and the degreasing rollers 38 clean the upper and lower surfaces of the cold-rolled sheet 1, further removing residual oil. Throughout the process, the adjusting rod 32 can adjust the position of the positioning roller 31 according to the actual situation to accommodate cold-rolled sheets 1 of different thicknesses. At the same time, the baffle 37 prevents oil from splashing out, ensuring a clean production environment. Finally, the cold-rolled sheet 1, cleaned and conveyed by the twin-roll conveyor assembly 3, will enter the multi-roll assembly 5 for subsequent processing.

[0074] Please see Figure 1 , Figure 8 as well as Figure 9 The cleaning component 7 includes a mounting frame 73. The inner side of the mounting frame 73 is provided with evenly spaced fixing shafts 71. A coating block 74 and a cleaning block 72 are installed at the fixing shafts 71. The side of the coating block 74 and the cleaning block 72 that contacts the cold-rolled plate 1 is flat.

[0075] The cleaning assembly 7 includes a mounting frame 73, which is generally made of metal, possessing a certain degree of strength and stability, such as aluminum alloy, to provide reliable support for the internal components. Inside the mounting frame 73, evenly spaced fixing shafts 71 are arranged. These fixing shafts 71 are typically cylindrical and can be made of materials with high hardness and corrosion resistance, such as stainless steel. The evenly spaced fixing shafts 71 provide an orderly arrangement for the installation of the coating block 74 and the cleaning block 72, ensuring the uniformity of cleaning and processing of the cold-rolled sheet 1.

[0076] A coating block 74 and a cleaning block 72 are installed at the fixed shaft 71, with the surfaces of the coating block 74 and cleaning block 72 that contact the cold-rolled sheet 1 being flat. The coating block 74 can be used to apply cleaning agents or similar substances to the surface of the cold-rolled sheet 1 to dissolve oil stains, while the cleaning block 72 is mainly used for further wiping and cleaning of residual fine oil stains and impurities on the surface of the cold-rolled sheet 1. The coating block 74 and cleaning block 72 can be made of different materials. For example, the cleaning block 72 can be made of a fibrous material with good adsorption and wiping capabilities, while the coating block 74 can be made of a suitable material, such as rubber, depending on the characteristics of the coating substance. When the cold-rolled sheet 1 passes through the cleaning assembly 7, the flat surfaces of the coating block 74 and cleaning block 72 make full contact with the surface of the cold-rolled sheet 1, achieving the functions of coating and cleaning.

[0077] The mounting frame 73 is provided with support components 4 at both the top and bottom. The support components 4 include telescopic members 42. One end of the piston rod of the telescopic member 42 is provided with a support block 41 for supporting the mounting frame 73.

[0078] Support components 4 are provided at both the top and bottom of the mounting frame 73. These components ensure the stability of the mounting frame 73, enabling it to accurately contact the cold-rolled sheet 1 for cleaning and coating operations. The support components 4 include a telescopic member 42, which can be a hydraulic telescopic cylinder or an electric telescopic push rod, allowing for the extension and retraction of a piston rod. A support block 41 is provided at one end of the piston rod of the telescopic member 42. The support block 41 is typically a block structure, made of high-hardness plastic or metal. When the piston rod of the telescopic member 42 extends or retracts, the support block 41 provides support or adjusts the position of the mounting frame 73 to accommodate cold-rolled sheets 1 of different thicknesses or to adjust the cleaning and coating pressure. For example, when the cold-rolled sheet 1 is thicker, the telescopic member 42 can extend, raising the mounting frame 73 to ensure full contact between the coating block 74 and the cleaning block 72 and the cold-rolled sheet 1; when the cold-rolled sheet 1 is thinner, the telescopic member 42 can shorten, lowering the height of the mounting frame 73.

[0079] The air blowing assembly 6 includes a connecting frame 61, which is fixed to one end of the multi-roll assembly 5. A retaining frame 63 is provided at one end of the connecting frame 61, and a spraying assembly 62 is provided on the inner side of the retaining frame 63 for air blowing drying of the outer side of the cold-rolled sheet 1.

[0080] A connector 22 is provided on one side of the scraper 21, and one end of the connector 22 is fixed to the outside of the double roller conveyor assembly 3.

[0081] The air-blowing assembly 6 includes a connecting frame 61, one end of which is fixedly connected to one end of the multi-roll assembly 5, serving to connect the air-blowing assembly 6 and the multi-roll assembly 5 together, ensuring the positioning accuracy and stability of the air-blowing assembly 6. The other end of the connecting frame 61 is provided with a retaining frame 63, which is generally a square or rectangular frame made of metal. The retaining frame 63 serves to fix the spraying assembly 62, enabling it to accurately perform air-blowing operations on the cold-rolled sheet 1.

[0082] The inner side of the frame 63 is equipped with a spraying assembly 62, which can be an array of multiple nozzles. These nozzles can be connected to a high-pressure air source, such as a compressed air tank or an air compressor. When high-pressure gas is sprayed onto the surface of the cold-rolled sheet 1 through the nozzles, it can quickly dry the moisture on the surface of the cold-rolled sheet 1 and blow away some small impurities. The spraying angle and spraying pressure of the nozzles can be adjusted according to the actual situation to achieve the best drying and cleaning effect. For example, for cold-rolled sheets 1 with more oil stains on the surface, the spraying pressure can be appropriately increased; for some cold-rolled sheets 1 with more fragile surfaces, the spraying angle and pressure need to be adjusted to avoid damage.

[0083] A connector 22 is provided on one side of the scraper 21. The connector 22 can be a connecting rod or connecting plate made of metal. One end of the connector 22 is fixed to the outside of the double roller conveyor assembly 3. Through this connection method, the scraper 21 can form an integral part with the double roller conveyor assembly 3, ensuring the stability of the scraping assembly 2 during operation. When the cold-rolled sheet 1 moves under the drive of the double roller conveyor assembly 3, the scraper 21 can accurately scrape off the oil stains on the surface of the cold-rolled sheet 1. Furthermore, the fixing effect of the connector 22 can prevent the scraper 21 from shaking or shifting during the scraping process, thus improving the scraping effect.

[0084] During the operation of the entire high-efficiency strip wiper system, the cold-rolled sheet 1 first passes through the scraping assembly 2, where scraper 21 and friction blocks 23 initially remove a large amount of oil and dirt from its surface. Then, the cold-rolled sheet 1 enters the twin-roller conveyor assembly 3, where it is conveyed and further cleaned, moving smoothly towards the multi-roller assembly 5. During this process, scraper 21 maintains a stable connection with the twin-roller conveyor assembly 3 via connector 22, ensuring continuous scraping. When the cold-rolled sheet 1 passes through the cleaning assembly 7, coating blocks 74 and cleaning blocks 72, adjusted by the support assembly 4, make full contact with the surface of the cold-rolled sheet 1, performing cleaning and coating operations. Finally, the cold-rolled sheet 1 reaches the air-blowing assembly 6, where the spray assembly 62 dries it with air, ensuring its surface is free of oil, moisture, and impurities, and has a bright finish, completing the entire cleaning and treatment process.

[0085] Through the coordinated work of its components, the high-efficiency strip wiper can effectively solve the problems existing in the degreasing method, improve the cleaning and treatment effect on the surface of cold-rolled sheet 1, and meet the surface quality requirements of products such as stainless steel mirror panels.
