Description

Technical Field

[0001] This utility model relates to the field of aluminum foil processing equipment technology, and in particular to an aluminum foil surface cleaning device. Background Technology

[0002] Electrode foil is a core material of aluminum electrolytic capacitors, made from aluminum foil through a series of processes including etching and formation. During manufacturing, before the aluminum foil enters the formation bath, it undergoes immersion in a phosphoric acid bath. The main purpose of this treatment is to react the phosphoric acid with the aluminum foil to form a uniform phosphate conversion film on the aluminum foil surface. This inhibits excessive hydration during subsequent formation processes, resulting in a denser hydrated oxide film and ensuring the specific capacitance of the electrode foil and the reliability of the product.

[0003] However, after the aluminum foil reacts in the phosphate bath, its surface carries some of the phosphate bath solution into the formation bath, contaminating the composition of the formation bath solution and changing its pH value. This adversely affects the growth and formation of the hydrated oxide film during the formation process, resulting in problems such as uneven structure, increased defects, or decreased insulation performance of the hydrated oxide film, leading to a decline in the performance of the finished electrode foil. Utility Model Content

[0015] The aforementioned aluminum foil surface cleaning device includes a liquid removal component, a cleaning component, and a drying component. These components are sequentially installed at the output end of the phosphate bath. The aluminum foil passes through these components before entering the formation tank. The liquid removal component comprises a frame assembly, two extrusion components, and a scraping component.

Above the water tank assembly and located at both ends of the water tank assembly, a cleaning medium is sprayed onto the aluminum foil to rinse its surface. A drying component is installed at the second end of the water tank assembly to dry the rinsed aluminum foil. Thus, after the aluminum foil comes out of the phosphoric acid tank, most of the phosphoric acid solution on the surface of the aluminum foil is removed by the mechanical extrusion component and the scraping component. Then, the cleaning medium is sprayed onto the surface of the aluminum foil by two spray components to rinse away the residual phosphoric acid solution. After that, the aluminum foil is dried by the drying component to remove the residual cleaning medium on the surface of the aluminum foil. This significantly reduces the amount of phosphoric acid solution carried into the formation tank by the aluminum foil, reduces the contamination of the formation tank solution, and allows the subsequent hydrated oxide film to grow uniformly, thereby improving the performance of the finished electrode foil.

Detailed Implementation

[0031] The technical solutions and effects of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0032] Please refer to Figure 1 This utility model provides an aluminum foil surface cleaning device 10, including a liquid removal component 20, a cleaning component 30, and a drying component 40. The liquid removal component 20, the cleaning component 30, and the drying component 40 are sequentially installed at the output end of the phosphate bath. The aluminum foil enters the formation tank after passing through the liquid removal component 20, the cleaning component 30, and the drying component 40 in sequence. The liquid removal component 20 includes a frame assembly 21, two extrusion components 22, and a scraping component 23. The frame assembly 21 is installed at the output end of the phosphate bath, and the two extrusion components 22 are respectively installed at both ends of the frame assembly 21 to extrude the aluminum foil surface and initially remove the phosphate bath liquid from the aluminum foil surface. The scraping component 23 is installed on the frame assembly 21 and located between the two extrusion components 22 to scrape off the phosphate bath liquid from the aluminum foil surface. The cleaning component 30 includes a water tank assembly 31 and two spray components 32. The first end of the water tank assembly 31 is provided with... At the output end of the phosphate bath, two spraying components 32 are installed above the water tank component 31 and located at both ends of the water tank component 31, respectively, to spray cleaning medium onto the aluminum foil and rinse its surface. A drying component 40 is installed at the second end of the water tank component 31 to dry the rinsed aluminum foil. Thus, after the aluminum foil comes out of the phosphate bath, most of the phosphate bath liquid on the surface of the aluminum foil is removed by the mechanical extrusion component 22 and the scraping component 23. Then, the two spraying components 32 spray cleaning medium onto the surface of the aluminum foil to rinse away the residual phosphate bath liquid. After that, the drying component 40 dries the aluminum foil to remove the residual cleaning medium on the surface of the aluminum foil. This significantly reduces the amount of phosphate bath liquid carried into the formation tank by the aluminum foil, reduces the contamination of the formation tank liquid, and allows the subsequent hydrated oxide film to grow uniformly, thereby improving the performance of the finished electrode foil.

[0033] Please refer to Figures 2 to 7Furthermore, each extrusion assembly 22 includes a first extrusion roller 221 and a second extrusion roller 222. The two ends of the first extrusion roller 221 are rotatably connected to both sides of the frame assembly 21, and the two ends of the second extrusion roller 222 are height-adjustably mounted on both sides of the frame assembly 21. The second extrusion roller 222 is positioned above the first extrusion roller 221 to cooperate with the first extrusion roller 221 to form an extrusion gap through which aluminum foil can pass. The roller surfaces of both the first extrusion roller 221 and the second extrusion roller 222 are made of a flexible, corrosion-resistant material, such as corrosion-resistant rubber. To prevent the first extrusion roller 221 and the second extrusion roller 222 from damaging the aluminum foil surface during extrusion; specifically, the extrusion assembly 22 uses the first extrusion roller 221 and the second extrusion roller 222 to form an extrusion gap to extrude the aluminum foil, so as to initially remove the phosphate bath solution adhering to the aluminum foil surface; the roller surface is made of flexible corrosion-resistant material, which can not only avoid scratching the aluminum foil surface during extrusion, but also resist the corrosion of the phosphate bath solution, and at the same time form a buffer between the first extrusion roller 221, the second extrusion roller 222 and the aluminum foil to prevent the aluminum foil from being thinned due to excessive extrusion.

[0034] In this embodiment, bearings are provided on both sides of the frame assembly 21, and the roller shaft of the first extrusion roller 221 is connected to the bearings to realize the rotational connection between the first extrusion roller 221 and the frame assembly 21.

[0035] Please refer to Figures 2 to 7Furthermore, each end of the frame assembly 21 has two adjustment slots 211, which are vertically arranged and located on both sides of the frame assembly 21. An adjustment hole is located at the top of the frame assembly 21, above one of the adjustment slots 211. The two ends of the second extrusion roller 222 are slidably installed in the two adjustment slots 211. The extrusion assembly 22 also includes an adjustment screw 223, a square observation frame 224, and an L-shaped scale piece 225. The bottom of the adjustment screw 223 passes through the adjustment hole and is rotatably connected to one end of the second extrusion roller 222, and is threadedly connected to the adjustment hole. Rotating the adjustment screw 223 drives the second extrusion roller 222 to rise and fall along the adjustment slot 211, thereby adjusting the extrusion gap between the second extrusion roller 222 and the first extrusion roller 221. The square observation frame 224 is vertically fixed to the top of the frame assembly 21. The L-shaped scale element 225 is fixedly mounted on the adjusting screw 223, adjacent to the adjusting hole. Its vertical section extends slidably into the square observation frame 224 from the top. The L-shaped scale element 225 is evenly provided with several scale lines, so that the size of the extrusion gap can be obtained by reading the position of the scale line relative to the top of the square observation frame 224. Specifically, the height of the second extrusion roller 222 can be adjusted by the cooperation of the adjusting groove 211, the adjusting hole, the adjusting screw 223, the square observation frame 224, and the L-shaped scale element 225, so as to flexibly adjust the size of the extrusion gap. By rotating the adjusting screw 223 and reading the scale line, the operator can not only match the extrusion gap with aluminum foil of different thicknesses, but also ensure that the extrusion effect is stable and reliable, thereby avoiding problems such as aluminum foil damage or poor liquid removal effect caused by improper extrusion gap size.

[0036] In this embodiment, bearing seats are fitted at both ends of the second extrusion roller 222. The bearing seats are provided with cylindrical mounting parts. The bottom of the adjusting screw 223 is rotatably connected to the mounting parts to realize the rotatable connection between the adjusting screw and the second extrusion roller 222.

[0037] In this embodiment, the second extrusion roller 222 is an active roller, so that its roller surface can rotate with the movement of the aluminum foil, thereby keeping synchronized with the travel speed of the aluminum foil and preventing the second extrusion roller 222 from damaging the surface of the aluminum foil due to speed difference.

[0038] Please refer to Figures 2 to 7Furthermore, the scraping assembly 23 includes two mounting brackets 231 and four scraper groups 232. The two mounting brackets 231 are vertically staggered and fixedly installed on the frame assembly 21, and are located above and below the aluminum foil transport path, respectively. Each mounting bracket 231 is symmetrically provided with two scraper groups 232, and each scraper group 232 is aligned with the aluminum foil surface to scrape off the residual phosphate bath solution from the upper and lower surfaces of the aluminum foil, respectively. Specifically, the vertically staggered mounting brackets 231 and the four scraper groups 232 are aligned with the upper and lower surfaces of the aluminum foil to perform scraping operations to remove the residual phosphate bath solution after extrusion.

[0039] Please refer to Figures 2 to 7 Furthermore, each scraper assembly 232 includes a mounting base 2321 and a scraper 2322. The first end of the mounting base 2321 has at least two evenly spaced adjustment holes 2323 along its length, and the second end has a sliding groove 2324. The mounting end of the scraper 2322 can slidably extend into the sliding groove 2324. The mounting end of the scraper 2322 is evenly provided with at least two adjusting rods 2325. Each adjusting rod 2325 passes through the corresponding adjustment hole 2323 and is threadedly connected to an adjusting nut 2326. Each adjusting rod 2325 is fitted with a spring 2327. The two ends of the spring 2327 abut against the scraper 2322 and the mounting base 2321 respectively, providing elastic pressure to the scraper 2322 so that the working end of the scraper 2322 is in close contact with the aluminum foil surface. By rotating the adjusting nut 2326, the compression of the spring 2327 is changed, thereby adjusting the magnitude of the elastic pressure to ensure that the pressure of each scraper 2322 on the aluminum foil surface remains consistent. Specifically, the spring 2327 provides continuous elastic pressure to the scraper 2322, forcing the working end of the scraper 2322 to be in close contact with the surface of the aluminum foil. When the aluminum foil fluctuates due to tension fluctuations during continuous transmission, the compression and rebound of the spring 2327 can cause the scraper 2322 to move vertically within the groove 2324, thereby maintaining close contact between the working end of the scraper 2322 and the surface of the aluminum foil and ensuring the scraping effect of the scraper 2322. At the same time, the scrapers 2322 located above and below the aluminum foil transmission path have different directions of gravity due to their different installation positions. The scraper located above the aluminum foil transmission path has its gravity direction towards the aluminum foil, which will help increase the pressure of the scraper 2322 on the surface of the aluminum foil. The scraper located below the aluminum foil transmission path has its gravity direction away from the aluminum foil, which will partially offset the pressure provided by the spring 2327 and reduce the pressure of the scraper 2322 on the surface of the aluminum foil. Therefore, by rotating each adjusting nut 2326, the compression of each spring 2327 is adjusted to compensate for the influence of the gravity of the corresponding scraper 2322, so that the actual pressure of each scraper 2322 on the aluminum foil above and below the aluminum foil conveying path is consistent, so as to ensure that each scraper 2322 has a consistent scraping effect on the residual plating liquid on the aluminum foil surface.

[0040] Please refer to Figures 8 to 10 Furthermore, the water tank assembly 31 includes a water washing tank 311 and a first guide roller 312. The first end of the water washing tank 311 is located at the output end of the phosphate tank. The first guide roller 312 is rotatably installed in the water washing tank 311 to guide the forward trajectory of the aluminum foil. Specifically, the water tank assembly 31 collects cleaning waste liquid through the water washing tank 311 and stably guides the forward trajectory of the aluminum foil through the first guide roller 312, creating favorable conditions for the spray cleaning of the aluminum foil.

[0041] In this embodiment, bearings are provided on both sides of the washing tank 311, and the two ends of the roller shaft of the first guide roller 312 are connected to the bearings to realize the rotational connection between the first guide roller and the washing tank 311.

[0042] Please refer to Figures 8 to 10 Furthermore, each spray assembly 32 includes a spray frame 321, two second guide rollers 322, at least one upper spray pipe 323, and at least one lower spray pipe 324. The spray frame 321 is fixedly installed on the top of one end of the washing tank 311. The two second guide rollers 322 are rotatably installed at both ends of the spray frame 321 to guide the aluminum foil through the spray frame 321. The upper spray pipe 323 is fixedly installed on the spray frame 321 and located above the aluminum foil, and the lower spray pipe 324 is fixedly installed on the spray frame 321 and located below the aluminum foil. Each upper spray pipe 323 and each lower spray pipe 324 is provided with at least two nozzles 325, and the nozzles 325 all face towards... The cleaning medium is sprayed onto the upper or lower surface of the aluminum foil. Each upper spray pipe 323 and each lower spray pipe 324 is connected to an external liquid supply device through pipelines to provide the cleaning medium. Specifically, the spray assembly 32, through the combination of the spray frame 321, the second guide roller 322, the upper spray pipe 323 and the lower spray pipe 324, evenly sprays the cleaning medium onto the upper and lower surfaces of the aluminum foil to rinse away the residual phosphate bath solution on the surface of the aluminum foil. At the same time, the two second guide rollers 322 can not only guide the aluminum foil through the spray area, but also achieve full coverage of the aluminum foil surface with the nozzles 325 symmetrically arranged above and below the aluminum foil to improve the rinsing effect.

[0043] In this embodiment, bearings are provided on both sides of the spray frame 321, and the roller shafts of the two second guide rollers 322 are connected to the bearings to realize the rotational connection between the second guide rollers 322 and the spray frame 321.

[0044] In this embodiment, the height of the second guide roller 322 near the middle of the water washing tank 311 is lower than the height of the other second guide roller 322, so that the cleaning liquid remaining on the surface of the aluminum foil flows to the water washing tank 311 under the action of gravity and guidance, thereby reducing the cleaning medium carried on the surface of the aluminum foil.

[0045] External liquid supply equipment is equipment capable of supplying liquids, such as water pumps and storage tanks; the cleaning medium is deionized water.

[0046] Please refer to Figures 11 to 14 Furthermore, the drying component 40 includes an oven assembly 41, which includes a hot air box 411, at least one upper heating pipe 412, and at least one lower heating pipe 413. The hot air box 411 is located at the second end of the washing tank 311 and is higher than the top surface of the washing tank 311. Each upper heating pipe 412 is fixedly installed on the top surface inside the hot air box 411, and each lower heating pipe 413 is fixedly installed on the bottom surface inside the hot air box 411. Both the upper heating pipe 412 and the lower heating pipe 413 are located within the hot air box 411. In the middle section, the upper and lower surfaces of the aluminum foil are heated and dried separately. Specifically, the oven assembly 41 heats the upper and lower surfaces of the aluminum foil simultaneously through the upper heating pipe 412 and the lower heating pipe 413 in the hot air box 411 to achieve rapid drying. The concentrated arrangement of the heating pipes in the middle of the hot air box 411 can improve the efficiency of heat energy utilization, ensure that the aluminum foil is heated evenly during the drying process, and avoid local overheating or insufficient drying, so as to ensure that the aluminum foil reaches a suitable drying state before entering the forming tank.

[0047] Please refer to Figures 11 to 14Furthermore, the drying component 40 also includes a first air blowing assembly 42, which is located at the inlet end of the hot air box 411. The first air blowing assembly 42 includes an upper fan blade assembly 421, a lower fan blade assembly 422, and a first hot air pipe 423. The upper fan blade assembly 421 is installed on the top surface inside the hot air box 411, and the lower fan blade assembly 422 is installed on the bottom surface inside the hot air box 411. The upper fan blade assembly 421 and the lower fan blade assembly 422 have the same structure but are installed in opposite directions, and both include an air guide plate 4211. The system includes at least two fan blades 4212, a connecting rod 4213, and an adjusting shaft 4214. A guide plate 4211 is fixedly installed on the inner wall of the hot air box 411 to guide hot air to each fan blade 4212. The first end of each fan blade 4212 is rotatably connected to the hot air box 411, and the second end extends out of and is rotatably connected to the hot air box 411. The connecting rod 4213 is connected to the second end of each fan blade 4212 to enable synchronous rotation of each fan blade 4212. The first end of the adjusting shaft 4214 is connected to... A fan blade 4212 is fixedly connected to its second end, which has a positioning hole 4215. At least two fixing holes 414 are evenly distributed on the outer wall of the hot air box 411, centered on the first end of the adjusting shaft 4214. By fixing the positioning hole 4215 to the different fixing holes 414, each fan blade 4212 rotates synchronously under the drive of the connecting rod 4213, thereby adjusting the angle of the hot air blowing out. The air outlet of the first hot air pipe 423 is connected to the top and bottom of the hot air box 411 respectively. The air inlet is connected to an external heat source to provide hot air into the hot air box 411. Specifically, the first blowing assembly 42 provides adjustable hot air at the inlet of the hot air box 411 through the upper fan blade assembly 421, the lower fan blade assembly 422 and the first hot air pipe 423 to pre-dry the aluminum foil. By adjusting the angle of the fan blades 4212 by the adjusting shaft 4214, the operator can adjust the blowing angle of the hot air according to the transmission status and drying requirements of the aluminum foil, thereby achieving uniform pre-drying of the aluminum foil.

[0048] In this embodiment, the first end of the fan blade 4212 is a rotating shaft structure, which is connected to a bearing on the hot air box 411 to achieve a rotating connection.

[0049] Please refer to Figures 11 to 14Furthermore, the drying component 40 also includes a second air blowing assembly 43, which is located at the outlet end of the hot air box 411. The second air blowing assembly 43 includes an upper air blowing box 431, a lower air blowing box 432, and a second hot air pipe 433. The upper air blowing box 431 is installed on the top surface inside the hot air box 411, and its bottom surface is evenly provided with a plurality of upper air outlet holes 434. The lower air blowing box 432 is installed on the bottom surface of the inner wall of the hot air box 411, and its top surface is evenly provided with a plurality of lower air outlet holes 435. The air outlet end of the second hot air pipe 433 is connected to the upper air blowing box 431 and the lower air blowing box 432 respectively, and the air inlet end is connected to an external air source to blow air upwards into the air box. Hot air is supplied by the upper air box 431 and the lower air box 432, and a uniform air curtain is formed through the upper air outlet 434 and the lower air outlet 435 to dry the surface of the aluminum foil. Specifically, the second air blowing assembly 43 forms a uniform air curtain at the outlet end of the hot air box 411 through the upper air box 431, the lower air box 432 and the second hot air pipe 433 to finally dry the surface of the aluminum foil. The upper air outlet 434 and the lower air outlet 435 evenly opened on the upper air box 431 and the lower air box 432 can make the airflow distribution uniform and form a stable and gentle air curtain, thereby ensuring that the surface of the aluminum foil is completely dry and avoiding residual moisture from affecting the formation process.

[0050] In this embodiment, the external heat source is a device capable of providing hot air, such as an electric blower.

[0051] Example 1: Working process of aluminum foil surface cleaning device 10

[0052] 1. Based on the thickness of the aluminum foil, the operator sets the extrusion gap between the second extrusion roller 222 and the first extrusion roller 221 by referring to the position of the scale line on the L-shaped scale piece 225 at the top of the square observation frame 224;

[0053] 2. The operator rotates the adjusting nut 2326 of each scraper assembly 232 according to the thickness of the aluminum foil to compress or release the spring 2327, so that the scraper 2322 can be in close contact with the surface of the aluminum foil.

[0054] 3. The operator adjusts the angle of the blades 4212 of the upper blade group 421 and the lower blade group 422 by rotating the adjusting shaft 4214 according to the conveying speed of the aluminum foil;

[0055] 4. After the aluminum foil comes out of the phosphoric acid bath, it enters the desiccant component 20. In the desiccant component 20, it passes through an extrusion component 22, a scraping component 23, and another extrusion component 22 in sequence. The phosphoric acid bath liquid on the surface of the aluminum foil is initially removed by the extrusion gap of the extrusion component 22. The upper and lower surfaces of the aluminum foil are scraped by four scraper groups 232 to remove the residual phosphoric acid bath liquid.

[0056] 5. After exiting the liquid removal component 20, the aluminum foil enters the cleaning component 30. In the cleaning component 30, the aluminum foil first passes through a spray assembly 32, where the upper spray pipe 323 and the lower spray pipe 324 spray cleaning medium onto the surface of the aluminum foil for a first rinse. Subsequently, the aluminum foil enters the water washing tank 311 of the water tank assembly 31, where it is guided by the first guide roller 312. After leaving the water washing tank 311, the aluminum foil passes through a second spray assembly 32, where the upper spray pipe 323 and the lower spray pipe 324 spray cleaning medium onto the surface of the aluminum foil again for a second rinse.

[0057] 6. After rinsing, the aluminum foil enters the drying component 40. First, it passes through the first blowing assembly 42 located at the inlet end of the hot air box 411. The upper fan blade group 421 and the lower fan blade group 422 blow hot air onto the surface of the aluminum foil at a set angle for pre-drying. Then, the aluminum foil enters the middle of the drying oven assembly 41, where the upper heating pipe 412 and the lower heating pipe 413 heat and dry its upper and lower surfaces. After that, the aluminum foil passes through the second blowing assembly 43 located at the outlet end of the hot air box 411. The upper blowing box 431 and the lower blowing box 432 form a uniform air curtain through their air outlets to finally air dry the surface of the aluminum foil.

[0058] 7. The cleaned and dried aluminum foil is led out from the drying component 40 and enters the forming tank.

[0059] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
