Description

Technical Field

[0001] The present invention relates to the technical field of aluminum foil processing equipment, and specifically discloses an on-line aluminum foil cleaning and degreasing device. Background Art

[0002] As a raw material for pharmaceutical foils and food foils, aluminum foil needs to be effectively cleaned during its processing to remove surface impurities and residual oil stains, so as to improve the product safety, performance and appearance. The traditional on-line cleaning methods for aluminum foil are spray type and immersion type. The spray type cleaning has been eliminated due to large water consumption and environmental unfriendliness; the immersion type cleaning is to tow the aluminum foil into the cleaning tank, and use a brush roller to remove the surface impurities and oil stains, and then tow it out of the cleaning liquid, and use a wiping roller to wipe off the cleaning liquid on the surface.

[0003] The utility model patent with the application number 201721658680.1 discloses a cleaning device for finished pharmaceutical aluminum foil, including a cleaning device main body, a conveying roller, a first cleaning tank, a second cleaning tank, a third cleaning tank and a dryer. The surface of the conveying roller is attached with aluminum foil. An ultrasonic vibrator is fixedly installed on the inner wall of the first cleaning tank. A pipeline is connected to the lower side of the first cleaning tank. A control valve is fixedly installed at the right end of the pipeline. An impurity tank is fixed at the bottom of the pipeline, and a filter screen is fixedly installed at the upper left side of the impurity tank. A water pump is fixedly connected to the left end of the first cleaning tank. After the aluminum foil enters the second cleaning tank, the heating block is heated by an electromagnetic induction heater to increase the temperature of the organic solvent, so that the organic solvent in the second cleaning tank can better dissolve the oil stains on the surface of the aluminum foil, and then the cleaning brush is driven to rotate by a rotating motor to clean the oil stains on the surface of the aluminum foil. The disclosed cleaning device for finished pharmaceutical aluminum foil is an immersion type aluminum foil cleaning device, which improves the cleaning effect of the cleaning liquid on the surface impurities and oil stains of the aluminum foil through an ultrasonic oscillator and a heating block. However, most of the rolling oil remaining on the surface of the aluminum foil is insoluble in the cleaning liquid and floats on the upper layer of the cleaning liquid. As the cleaning time increases, more and more floating rolling oil will accumulate, resulting in part of the rolling oil adhering to the surface of the aluminum foil again when the aluminum foil is towed out of the cleaning liquid after cleaning. Even if a wiping roller is used for cleaning subsequently, it cannot be cleaned thoroughly, affecting the final cleaning effect of the aluminum foil. Therefore, in view of the above deficiencies of the existing cleaning device for finished pharmaceutical aluminum foil, the present application proposes an on-line aluminum foil cleaning and degreasing device that can effectively solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide an on-line aluminum foil cleaning and degreasing device to solve the problem that in the existing cleaning device for finished pharmaceutical aluminum foil during the cleaning process, due to the inability to remove the oil stains floating on the upper layer of the cleaning liquid in a timely manner, when the aluminum foil is towed out of the cleaning liquid after cleaning, the floating oil stains will adhere to its surface again, resulting in secondary pollution.

[0005] The present invention is achieved through the following technical solutions: The cleaning roller of the cleaning tank is fixed on the inner wall of the cleaning tank, and the cleaning roller is provided with a brushing mechanism, and the cleaning roller is provided with a wiping mechanism. The cleaning roller above the cleaning roller is provided with a floating oil removing mechanism, and the floating oil removing mechanism comprises a piston cylinder arranged on the outer surface of the cleaning tank, the end of the piston cylinder is connected with a bellows telescopic tube extending into the cleaning tank, the end of the bellows telescopic tube is connected with an inflatable bag, a sealing piston is arranged in the piston cylinder, one end of the sealing piston is connected with a push rod penetrating the bellows telescopic tube and acting on the end of the inflatable bag, and the other end of the sealing piston is connected with a transmission mechanism for pushing the sealing piston to reciprocate. An oil cleaning shovel cylinder sleeved on the outer periphery of the bellows telescopic tube is fixed on the inner wall of the cleaning tank, an oil receiving tank is arranged below the oil cleaning shovel cylinder, and the lower end of the oil receiving tank is connected with an oil drain pipe extending out of the cleaning tank.

[0006] During the operation of the aluminum foil online cleaning and degreasing device disclosed by the present invention, the aluminum foil is introduced into the cleaning liquid of the cleaning tank, and the oil stains and impurities on the surface are scrubbed off by the scrubbing mechanism at the first time, and then the aluminum foil is wiped by the wiping mechanism before being pulled out of the cleaning tank to remove the cleaning liquid carried on the surface.

[0007] The cleaned oil will float on the upper layer of the cleaning liquid. At the same time, the floating oil removal mechanism operates synchronously, and the transmission mechanism pushes the sealing piston toward one side of the inflatable bag, so that the compressed gas and the push rod make the inflatable bag expand and become rugby-shaped, so that the lower end of the inflatable bag contacts the floating oil on the upper layer, so that the oil adheres to the lower end surface of the inflatable bag. When the sealing piston moves in the opposite direction, the bellows shortens, and the inflatable bag begins to shrink. In the process of being collected into the oil cleaning shovel cylinder, the oil originally attached to the surface of the inflatable bag is shoveled off through the end of the oil cleaning shovel cylinder. The shoveled oil will drip into the oil receiving tank and finally be discharged from the cleaning tank through the oil drain pipe. Through the online operation of the floating oil removal mechanism, the oil removed from the aluminum foil and floating on the upper layer of the cleaning liquid can be continuously cleaned out, which can effectively prevent the aluminum foil from being re-adhered to the oil in the process of being pulled out of the cleaning liquid, avoid secondary pollution, and improve the cleaning effect of the aluminum foil.

[0008] As a further configuration of the above scheme, the transmission mechanism includes a cylinder which is rotatably arranged directly below the piston cylinder through a center rod, the outer end of the center rod is connected to a power assembly, and a guide groove composed of two mirror-symmetrical spiral segments and an arc segment is provided on the outer circular surface of the cylinder, the other end of the sealing piston is connected to a piston rod, and the outer end of the piston rod is provided with a guide wheel which acts on the guide groove.

[0009] As a further setting of the above solution, a plurality of piston cylinders are arranged side by side. The power assembly includes a power rod perpendicular to the central rod. The end of the power rod is connected with a power motor. Active bevel gears corresponding to each piston cylinder are arranged on the power rod. Driven bevel gears meshing with the corresponding active bevel gears are arranged at the ends of each central rod.

[0010] The above is the specific way for the transmission mechanism to drive a single oil slick removal mechanism or multiple oil slick removal mechanisms. Through the power input of the power motor and the meshing transmission between the bevel gears, the cylinder can be rotated. During the rotation of the cylinder, through the cooperation between the guide wheel at the end of the piston rod and the guide groove, the sealing piston is pushed to reciprocate in the piston cylinder, so that the inflatable air bag can continuously change during the process of expanding to adhere to the oil stain and shrinking to remove the oil stain.

[0011] As a further setting of the above solution, the piston cylinder is rotatably arranged on a waterproof bearing on the side of the cleaning tank. A gear ring is arranged on the outer circumferential surface of the piston cylinder. An incomplete gear meshing with the gear ring is arranged on the central rod. The tooth surface part of the incomplete gear is axially aligned with the arc segment in the guide groove. The piston rod is rotatably connected with the sealing piston. A cross bar frame for guiding and limiting the piston rod is fixed on the outer side surface of the piston cylinder.

[0012] The above is the improved design of the oil slick removal mechanism in the present invention. It can not only drive the inflatable air bag to continuously operate in the actions of expanding to adhere to the oil stain and shrinking to remove the oil stain through the transmission mechanism. When the inflatable air bag expands to the maximum and is in an olive shape, it can drive the inflatable air bag to rotate together with the piston cylinder through the meshing transmission between the incomplete gear and the gear ring, so that the surface of the expanded inflatable air bag can successively rotate and contact the oil stain floating on the upper layer, thereby fully adhering to and removing the oil stain, effectively improving the contact area between the inflatable air bag as an oil stain removal carrier and the oil stain, and improving the oil stain removal effect.

[0013] As a further setting of the above solution, one end of the oil cleaning shovel cylinder facing the inflatable air bag is arranged in a blade ring shape. The end of the ejector rod is arranged in a spherical shape. The design that the end of the oil cleaning shovel cylinder is in a blade ring shape can ensure that the oil stain adhered to the surface of the inflatable air bag can be effectively shoveled off during the process of the inflatable air bag shrinking and retracting. The design that the end of the ejector rod is in a spherical shape can prevent the ejector rod from puncturing the inflatable air bag during the process of pushing the inflatable air bag to expand, ensuring the service life and stability of the inflatable air bag.

[0014] As a further setting of the above solution, the oil receiving tank is arranged above the cleaning liquid in the cleaning tank. After the inflatable air bag expands, it is in an olive shape and its lower end extends into the cleaning liquid.

[0015] As a further setting of the above solution, the brushing mechanism includes two brush rollers distributed on both sides of the aluminum foil. Brush hairs in contact with the surface of the aluminum foil are provided on the roller bodies of the brush rollers, and a brushing driving device is connected to the ends of the two brush rollers.

[0016] As a further setting of the above solution, the wiping mechanism includes two wiping rollers distributed on both sides of the aluminum foil, and a wiping driving device is connected to the ends of the two wiping rollers.

[0017] As a further setting of the above solution, the wiping roller includes a hollow inner core roller and a sponge adsorption layer. The sponge adsorption layer is arranged on the outer circumferential surface of the hollow inner core roller. Through holes are formed on the outer circumferential surface of the hollow inner core roller. One end of the hollow inner core roller is connected to the wiping driving device, and the other end is provided with a hollow roller shaft. A suction pipe with an end extending out of the hollow roller shaft is arranged in the hollow inner core roller, and a suction strip opening in fit with the inner wall of the hollow inner core roller is arranged on the suction pipe located in the hollow inner core roller. The outer end of the suction pipe is connected with a negative pressure suction device through a negative pressure suction pipe. An extrusion roller aligned with the opening direction of the suction strip opening is rotatably arranged in the cleaning tank, and the extrusion roller is in extrusion contact with the sponge adsorption layer.

[0018] As a further setting of the above solution, a feeding guide roller is arranged in the cleaning tank near the position of the feeding port, and a discharging guide roller is arranged in the cleaning tank near the position of the discharging port. There are two dipping rollers which are respectively arranged on the left and right sides at the lower end of the cleaning tank.

[0019] The above is a further improvement design of the present invention for the structure of the existing wiping roller. Through the above design, during the process that the aluminum foil passes through the wiping mechanism, the surface of the aluminum foil is wiped by the sponge adsorption layer and the residual cleaning liquid on the surface is sucked away. Then the sponge adsorption layer rotates with the hollow inner core roller to contact with the extrusion roller, and the adsorbed cleaning liquid is extruded under the extrusion action. At the same time, due to the suction effect of the negative pressure suction device on the suction pipe, a negative pressure is formed inside it. At this time, the extruded cleaning liquid can be sucked into the suction strip opening through the through holes, and finally sent out of the wiping roller by the negative pressure suction pipe, ensuring that the wiping roller can maintain a good dry state during long-term operation, avoiding the surface quality problem that the existing wiping roller cannot fully absorb the residual cleaning liquid during the process of wiping the surface of the aluminum foil due to excessive water absorption inside, resulting in liquid spots on the surface of the aluminum foil after drying, and effectively ensuring the cleaning effect of the aluminum foil.

[0020] Compared with the prior art, the present invention has the following beneficial effects: The aluminum foil online cleaning and degreasing device disclosed in the present invention can remove the oil floating on the upper layer of the cleaning liquid from the cleaning tank in time through the design of the floating oil removing mechanism, thereby solving the problem of secondary pollution caused by the aluminum foil after cleaning being re-adhered to the oil during the process of being pulled out of the cleaning liquid, and effectively improving the cleaning effect of the aluminum foil.

[0021] The floating oil removal mechanism of the present invention adopts a special structural design. By utilizing the cooperation of components such as a piston cylinder, an inflatable bag, an oil cleaning shovel cylinder, and a transmission mechanism, the inflatable bag can continuously reciprocate in the process of expanding to adhere to the oil and shrinking to remove the oil, thereby continuously discharging the oil floating on the upper layer of the cleaning liquid out of the cleaning tank. The overall structural design is novel and ingenious. Under the premise of not affecting the online cleaning of the aluminum foil, the secondary pollution problem caused by the floating oil is effectively avoided.

[0022] The present invention further improves the structure of the wiping roller in the wiping mechanism. In the process of wiping the cleaned aluminum foil, the sponge adsorption layer wipes the aluminum foil and absorbs the residual cleaning liquid, and then the squeezing roller is used to squeeze out the cleaning liquid in the sponge adsorption layer. Combined with the internal negative pressure suction effect, the squeezed cleaning liquid can be sucked out of the wiping roller in time, so that the wiping roller can always maintain a good wiping and adsorption effect, effectively solving the problem of surface quality of the existing wiping roller that absorbs too much water inside, resulting in the inability to fully absorb the residual cleaning liquid during the wiping process of the aluminum foil surface, resulting in liquid spots on the surface of the aluminum foil after drying, and effectively ensuring the cleaning effect of the aluminum foil.

[0026] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will refer to the attached Figures 1 to 9 drawings and describe the present application in detail in conjunction with the embodiments. Embodiment 1

[0027] Embodiment 1 discloses an on-line cleaning and degreasing device for aluminum foil. Referring to the attached Figures 1 - 3 drawings, the main body of the device includes a cleaning tank 1 with an open upper end. The upper ends of the left and right side surfaces of the cleaning tank 1 are respectively provided with a discharge port 102 and a feed port 101. A feed guide roller 103 is arranged in the cleaning tank 1 near the feed port 101, and a discharge guide roller 104 is arranged in the cleaning tank 1 near the discharge port 102. Immersion rollers 105 corresponding to the feed guide roller 103 and the discharge guide roller 104 are arranged on both the left and right sides at the lower end of the cleaning tank 1, so that the middle part of the aluminum foil 100 can fully enter the cleaning liquid under the guiding action of the feed guide roller 103, the discharge guide roller 104 and the two immersion rollers 105. In addition, corresponding water supply pipes and drain pipes (not shown in the figures) are also arranged on the cleaning tank 1 for timely replenishment and replacement of the cleaning liquid in the cleaning tank 1.

[0028] A brushing mechanism 2 is arranged between the feed guide roller 103 and the corresponding immersion roller 105. The brushing mechanism 2 includes brush rollers 201 arranged on both sides of the aluminum foil 100. Brush hairs in contact with the surface of the aluminum foil 100 are arranged on the roller bodies of the brush rollers 201. Then, a brushing driving device 202 is also arranged at the front ends of the two brush rollers 201. A wiping mechanism 3 is arranged between the discharge guide roller 104 and the discharge port 102. The wiping mechanism 3 includes wiping rollers 301 arranged on the upper and lower sides of the aluminum foil 100, and a wiping driving device 302 is arranged at the front ends of the two wiping rollers 301.

[0029] Reference appendix Figure 4 appendix Figure 5 appendix Figure 6 and appendix Figure 9 , an oil floating removal mechanism 4 is arranged at the upper end of the cleaning tank 1 between two dipping rollers 105, and a transmission mechanism 5 for driving the oil floating removal mechanism 4 is arranged on the front side of the cleaning tank 1. The oil floating removal mechanism 4 includes a plurality of horizontally arranged piston cylinders 401 arranged side by side, specifically, it can be set between 3 and 5, and the specific quantity is determined by the length of the cleaning tank 1. One end of the piston cylinder 401 extends into the cleaning tank 1, and a corrugated telescopic pipe 402 is connected to the front end of the piston cylinder 401. The front end of the corrugated telescopic pipe 402 is hermetically connected to an air charging balloon bag 403. Specifically, when connecting, the air charging balloon bag 403 and the corrugated telescopic pipe 402 can be detachably connected through a clamp 400, so as to facilitate the replacement of the air charging balloon bag 403 after it is damaged.

[0030] A sealing piston 404 is arranged in the piston cylinder 401. A push rod 405 concentric with the corrugated telescopic pipe 402 and extending into the air charging balloon bag 403 is connected to the sealing piston 404, and the end of the push rod 405 is designed to be spherical, so that when the piston cylinder 401 moves towards the air charging balloon bag 403, the air charging balloon bag 403 can be inflated to an olive shape under the action of compressed gas and the push rod 405. A clear oil shovel cylinder 406 fixedly connected to the side wall of the cleaning tank 1 is coaxially sleeved outside the corrugated telescopic pipe 402, and one end of the clear oil shovel cylinder 406 facing the air charging balloon bag 403 is designed to be a blade ring shape. An oil receiving tank 407 is arranged in the cleaning tank 1 below the clear oil shovel cylinder 406. The oil receiving tank 407 is arranged higher than the liquid level of the internal cleaning liquid, and a drain pipe 408 extending out of the cleaning tank 1 is connected to the lower end of the oil receiving tank 407.

[0031] The transmission mechanism 5 includes a transmission box 501 fixedly arranged on the front side of the cleaning tank 1, and the piston cylinder 401 is located in the transmission box 501. A cylinder 502 is arranged directly below each piston cylinder 401. The cylinder 502 is arranged parallel to the piston cylinder 401 and is rotatably arranged in the transmission box 501 through a central rod 503. A guide groove 504 is arranged on the outer circumferential surface of the cylinder 502. The guide groove 504 is composed of two mirror-symmetrical spiral segments 5041 and an arc segment 5042. One ends of the two spiral segments 5041 are transitionally connected, and the other ends of the two spiral segments 5041 are respectively connected to the two ends of the arc segment 5042, thus forming a closed-loop guide groove. In addition, a power assembly for simultaneously driving all the cylinders 502 to rotate is arranged on the front side of the transmission box 501. The power assembly includes a power rod 505 arranged perpendicular to the central rod 503. One end of the power rod 505 is connected with a power motor 506, and a driving bevel gear 507 corresponding to each central rod 503 is arranged on the power rod 505. Then driven bevel gears 508 meshing with the corresponding driving bevel gears 507 are arranged at the ends of all the central rods 503.

[0032] The transmission mechanism 5 further includes a piston rod 509 connected to the sealing piston 404 and extending out of the piston cylinder 401. The outer end of the piston rod 509 is rotatably connected through a pin shaft with a guide wheel 510 acting on the guide groove 504. Then a cross bar frame 511 for guiding and limiting a row of piston rods 509 is fixed in the transmission box 501. A limiting through hole for passing through the piston rod 509 is arranged on the cross bar frame 511, ensuring that the piston rod 509 does not rotate during the linear pushing process, so that the guide wheel 510 can fully cooperate with the guide groove 504.

[0033] During the operation of the aluminum foil on-line cleaning and degreasing device disclosed in the first embodiment, the aluminum foil 100 enters from the feed port 101 under the guiding action of the feed guiding roller 103, the discharge guiding roller 104 and the two immersion rollers 105, is fully immersed in the cleaning liquid after passing through the two immersion rollers 105, and is then pulled out from the discharge port 102. At the first moment when the aluminum foil 100 enters the cleaning liquid, the two side surfaces of the aluminum foil are brushed by the brushing mechanism 2, so that the impurities and oil stains on its surface can be separated. The separated oil stains will float on the upper layer of the cleaning liquid. After being washed through the bottom of the cleaning tank 1, it is guided by the discharge guiding roller 104 into the wiping mechanism 3, and the residual cleaning liquid on the surface is removed by the upper and lower wiping rollers 301.

[0034] Meanwhile, start the power motor 506, and under the meshing transmission of the bevel gears, rotate all the cylinders 502. During the rotation of the cylinders 502, the piston rod 509 moves along the axis direction of the piston cylinder 401 through the interaction between the guiding groove 504 and the guiding wheel 510. When the piston cylinder 401 is pushed towards the inner end of the piston cylinder 401, the gas in the piston cylinder 401 will be pressed into the inflatable airbag 403 through the sealing piston 404. Meanwhile, under the action of the ejector rod 405, the corrugated expansion pipe 402 extends. At the same time, after the inflatable airbag 403 extends out of the clean oil shovel barrel 406, it begins to expand until it becomes olive-shaped and its lower surface contacts the oil stain floating on the upper layer of the cleaning liquid, allowing the oil stain to adhere to its surface.

[0035] Subsequently, during the retraction of the sealing piston 404, the inflatable airbag 403 gradually shrinks, and the corrugated expansion pipe 402 retracts. Thus, during the retraction of the inflatable airbag 403, its lower surface contacts the blade ring end of the clean oil shovel barrel 406, and the oil stain attached to the lower surface of the inflatable airbag 403 is shoveled off by the clean oil shovel barrel 406. The shoveled oil stain drips into the oil receiving groove 407 and is finally discharged by the drain pipe 408.

[0036] During the continuous operation of the floating oil removal mechanism 4, the oil stains that are continuously cleaned from the surface of the aluminum foil and float above the cleaning liquid can be cleaned in time, avoiding the aluminum foil 100 from being stained with oil stains when it is pulled out of the cleaning liquid after cleaning, avoiding secondary pollution, and ensuring the cleaning effect. Embodiment 2

[0037] Embodiment 2 discloses an on-line cleaning and degreasing device for aluminum foil, which is an optimized and improved design based on the technical solution in Embodiment 1. The same parts as those in Embodiment 1 will not be described again.

[0038] Refer to the attached Figure 5 and the attached Figure 6 In this Embodiment 2, during the optimization design, the front end of the piston cylinder 401 is rotatably connected to the waterproof bearing on the side wall of the cleaning tank 1, and under the action of the sealing piston 404, the ejector rod 405, and the corrugated expansion pipe 402, the inflatable airbag 403 can rotate together with the piston cylinder 401 when it is filled with gas and is olive-shaped. Meanwhile, a bearing 512 is provided at the center of the end face where the sealing piston 404 is connected to the piston rod 509, and then the end of the piston rod 509 is rotatably connected to the bearing 512, so that the piston rod 509 can maintain a rotating state relative to the sealing piston 404.

[0039] Meanwhile, a gear ring 513 is provided on the outer surface of the piston cylinder 401, an incomplete gear 514 that interacts with the gear ring 513 is provided on the central rod 503, and the tooth surface part of the incomplete gear 514 is axially aligned with the arc segment 5042 in the guiding groove 504.

[0040] In Embodiment 2, through the above optimization design, when the guide wheel 510 acts on the arc section 5042 in the guide groove 504, the air-filled balloon bag 403 is inflated to the maximum and is in an olive shape, and its lower end is immersed in the cleaning liquid. At this time, the incomplete gear 514 begins to mesh with the gear ring 513, and through the meshing transmission of the gears, the piston cylinder 401, the sealing piston 404, the ejector rod 405, the corrugated telescopic tube 402, and the air-filled balloon bag 403 rotate synchronously. During the rotation of the air-filled balloon bag 403, its outer surface can adhere to all the floating oil on the upper layer of the cleaning liquid, increasing the contact area between the air-filled balloon bag 403 and the floating oil. Finally, when the guide wheel 510 acts on the spiral section 5041 in the guide groove 504, under the action of the piston rod 509, the sealing piston 404 retracts, the air-filled balloon bag 403 gradually becomes smaller, and the corrugated telescopic tube 402 retracts. Thus, during the retraction of the air-filled balloon bag 403, its entire outer surface contacts the blade ring end of the oil cleaning shovel tube 406, and the oil stains attached to the surface of the air-filled balloon bag 403 are shoveled off by the oil cleaning shovel tube 406. The shoveled oil stains drip into the oil receiving groove 407 and are finally discharged by the drain pipe 408. Compared with Embodiment 1, it has a better effect of removing floating oil. Embodiment 3

[0041] Embodiment 3 discloses an on-line aluminum foil cleaning and deoiling device which is further designed based on the technical solutions in Embodiment 1 or Embodiment 2. The same parts as those in Embodiment 1 or Embodiment 2 will not be described again.

[0042] In this Embodiment 3, the wiping mechanism 3 is mainly improved and designed so that during the process of the wiping roller 301 wiping and removing the cleaning liquid on the surface of the aluminum foil, the absorbed cleaning liquid can be discharged in time, avoiding excessive cleaning liquid adsorbed by the wiping roller 301 itself, which may cause the inability to wipe and adsorb the cleaning liquid on the surface of the aluminum foil.

[0043] Refer to the attached Figure 7 and the attached Figure 8 In this Embodiment 3, the wiping roller 301 includes a hollow inner core roller 3011. A plurality of through holes 3012 are uniformly opened on the outer circumferential surface of the hollow inner core roller 3011, and a sponge adsorption layer 3013 in contact with the aluminum foil 100 is coated on the outer surface of the hollow inner core roller 3011. Solid roller shafts 3014 and hollow roller shafts 3015 are respectively arranged on both end faces of the hollow inner core roller 3011. The solid roller shaft 3014 is connected to the wiping driving device 302, and the hollow roller shaft 3015 rotates and extends out of the cleaning tank 1.

[0044] Inside the hollow inner core roller 3011, a suction pipe 3016 with its end extending out of the hollow roller shaft 3015 is provided, and the suction pipe 3016 is fixedly connected to the cleaning tank 1 through a connecting member 303. On the suction pipe 3016 located inside the hollow inner core roller 3011, a suction strip opening 3017 is provided which faces away from the aluminum foil 100 and is in contact with the inner wall of the hollow inner core roller 3011. Finally, a negative pressure suction device 304 is also provided outside the cleaning tank 1, and a negative pressure suction pipe 305 connected to the outer ends of the two suction pipes 3016 is connected to the negative pressure suction device 304.

[0045] In addition, two squeezing rollers 306 are rotatably provided in the cleaning tank 1. The two squeezing rollers 306 are arranged in the opening direction corresponding to the suction strip opening 3017 and are both in squeezing contact with the sponge adsorption layer 3013.

[0046] In this embodiment 3, through the above design of the wiping mechanism 3, when the aluminum foil passes through the wiping mechanism 3 after the degreasing cleaning is completed, the surface of the aluminum foil 100 is wiped by the sponge adsorption layer 3013 and the cleaning liquid remaining on its surface is sucked away. Then, the sponge adsorption layer 3013 is compressed by the squeezing roller 306. Coupled with the negative pressure suction effect of the internal suction pipe 3016, the cleaning liquid extruded from the sponge adsorption layer 3013 can enter the suction pipe 3016 through the through holes 3012 on the hollow inner core roller 3011, and finally is discharged by the negative pressure suction pipe 305 and the negative pressure suction device 304. This ensures the wiping and absorption effect of the cleaning liquid on the aluminum foil surface during the long-term operation of the wiping roller 301, avoids the residual cleaning liquid on the aluminum foil surface, and prevents the formation of liquid spots after drying, thus improving the cleaning effect of the aluminum foil.

[0047] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
