Description

Technical Field

[0001] The invention relates to the field of aluminum foil cleaning, in particular to an aluminum foil cleaning device. Background Art

[0002] Aluminum foil is an extremely thin metal sheet obtained by rolling aluminum and aluminum alloy strip coils. Its thickness is usually less than 0.2 mm. Aluminum foil has excellent barrier properties and can effectively isolate food from external environmental pollution such as light, air, water and microorganisms, ensuring the freshness and quality of food. Therefore, aluminum foil is widely used in the field of food packaging. During the processing of aluminum foil, stains usually adhere to the surface of the aluminum foil, and it is often necessary to clean the surface before leaving the factory to ensure that the surface of the aluminum foil is clean enough and has good gloss.

[0003] At present, a Chinese invention patent application with publication number CN116460081A and publication date July 21, 2023 proposes an aluminum foil cleaning device, including a spraying mechanism, a cleaning mechanism and a drying mechanism, the cleaning mechanism including a mounting frame, an upper cleaning assembly and a lower cleaning assembly, the latter two both including a core shaft, the core shaft and the mounting frame are fixed by an anti-rotation shaft, a drive shaft is movably arranged in the middle of the core shaft, and a drive gear is provided at one end of the drive shaft; the side wall of the core shaft has an annular groove, two mounting shafts are passed through the inside, the mounting shaft sleeve is provided with a cleaning roller, and a locking assembly and a driven gear are provided at one end of the mounting shaft; the locking assembly includes a limit block, and the limit block is threadedly connected to the mounting shaft.

[0004] When in use, one of the cleaning rollers is used to clean the surface of the aluminum foil, and the other cleaning roller is used as a spare. When working, the driving gear is driven to rotate through the driving shaft, and then the driven gear and the mounting shaft are driven to rotate to make the cleaning roller work. When replacement is needed, the machine is stopped, the limit block on the mounting shaft corresponding to the cleaning roller to be replaced is turned to make the block away from the driven gear, and then the driven gear is slid to be staggered with the driving gear, and the limit block on the mounting shaft corresponding to the spare cleaning roller is turned to make the driven gear on the mounting shaft mesh with the driving gear, and finally the anti-rotation shaft is loosened to make the core shaft rotate as a whole, so that the original spare cleaning tube is rotated to the working position and the anti-rotation shaft is locked to complete the replacement of the cleaning roller.

[0005] With regard to the above-mentioned related technologies, the cleaning roller can wipe the surface of the aluminum foil and absorb some of the water on the aluminum foil. However, after the cleaning device is full of water, it cannot continue to absorb water. The only way to enable it to continue to absorb water is to replace the cleaning roller. However, the cleaning device needs to be replaced frequently, which affects work efficiency. After the aluminum foil is washed with water, water will adhere to the surface. During the backward transportation process, the aluminum foil with water adherence is prone to dust. At the same time, when it is dried, watermarks will form on the surface of the aluminum foil after the water dries, affecting the glossiness of the aluminum foil surface. Therefore, after the aluminum foil is cleaned, the water adhered to the surface of the aluminum foil needs to be cleaned off in time. Summary of the invention

[0006] In order to improve the efficiency of cleaning and absorbing water on the surface of the aluminum foil by a cleaning roller after the aluminum foil is washed with water, the present invention provides an aluminum foil cleaning device.

[0007] The present invention provides an aluminum foil cleaning device, which adopts the following technical solution:

[0008] An aluminum foil cleaning device comprises a conveying mechanism, a cleaning mechanism for cleaning the surface of the aluminum foil, and a drying mechanism for drying the aluminum foil, wherein the drying mechanism is arranged behind the cleaning mechanism along the conveying direction of the aluminum foil;

[0009] A wiping mechanism is also provided between the cleaning mechanism and the drying mechanism, and the wiping mechanism comprises a mounting frame, two wiping rollers for absorbing water from two surfaces of the aluminum foil respectively, and a plurality of reversing rollers;

[0010] The wiping roller comprises a roller shaft, a roller core, a sealing sleeve, a water-absorbing roller sleeve, a water-absorbing pipe and a closing component, wherein the roller shaft is fixedly arranged on the mounting frame, the roller core is cylindrical, and two side walls of the roller core are rotatably mounted on the roller shaft through the sealing sleeve, a plurality of air holes are evenly distributed on the circumference of the roller core, the water-absorbing roller sleeve is sleeved on the outer circumference of the roller core, the closing component is fixedly arranged on the roller shaft, the outer circumference of the closing component is arc-shaped, the outer circumference of the closing component and the roller core are coaxially arranged, the outer circumference of the closing component is arranged tightly against the inner circumference of the roller core, the closing component is used to block the air holes on the roller core away from the aluminum foil, one end of the water-absorbing pipe passes through the roller shaft and is arranged inside the roller core, the other end of the water-absorbing pipe is connected to the negative pressure air source outside the roller core, and the water-absorbing pipe is arranged above the closing component;

[0011] The mounting frame is also provided with a driving device, which is drivingly connected to the roller core.

[0012] By adopting this technical solution, the interior of the wiping roller is connected to the negative pressure air source through the water suction pipe, so the interior of the wiping roller is in a negative pressure state, and a plurality of ventilation holes are provided on the peripheral surface of the wiping roller, so that the wiping roller can attract objects on the surface of the wiping roller. When the aluminum foil passes through the wiping roller, one end face of the aluminum foil is attached to the water suction roller sleeve on the surface of the wiping roller for transmission, and the water suction roller sleeve will adhere to the surface of the aluminum foil to wipe the aluminum foil and absorb the water on the aluminum foil. When a large amount of water is absorbed by the water suction roller sleeve, the water in the water suction roller sleeve will be sucked into the wiping roller through the ventilation holes provided on the roller core by the negative pressure inside the wiping roller. The water in the roller core gradually converges to the closed component that is in close contact with the inner wall of the roller core. The water suction pipe on the closed component will promptly absorb the water on the closed component and discharge it from the wiping roller. At the same time, the closed component will also block the vents on the roller core that are far away from the aluminum foil, reducing the number of vents that can be ventilated. Without changing the negative pressure inside the roller core, the vents on the roller core that are close to the aluminum foil can generate greater attraction. The driving device can prevent the friction between the closed component and the wiping roller from being too large, which makes it difficult for the wiping roller to rotate under the drive of the aluminum foil, and provide the power for the wiping roller to rotate. In this way, by connecting the negative pressure inside the wiping roller, not only can the aluminum foil be adsorbed on the water-absorbing roller sleeve so that the water-absorbing roller sleeve absorbs the water on the surface of the aluminum foil, but also the water in the water-absorbing roller sleeve can be more efficiently absorbed into the roller core, so that less water is stored in the water-absorbing roller sleeve. Without replacing the wiping roller, the water on the surface of the aluminum foil can be absorbed more cleanly, saving the time spent on replacing the wiping roller.

[0013] Optionally, the closing component includes a fixing member, a supporting member and a sealing member, the fixing member is connected to the roller shaft, the supporting member fixedly connects the fixing member and the sealing member, the outer wall of the sealing member is arranged in an arc shape, the outer wall of the sealing member and the inner wall of the roller core are in sliding contact, and the outer wall of the sealing member and the inner wall of the roller core are arranged in a sealing manner.

[0014] By adopting this technical solution, the seal is fixedly connected to the roller shaft through the fixing member and the supporting member. When the roller core rotates on the roller shaft, the seal can block the directional vents, so that air can only enter from the vents in the direction of contact with the aluminum foil and the wiping roller. Without changing the negative pressure inside the roller core, the air can enter the roller core from the vents in the direction of contact between the wiping roller and the aluminum foil as much as possible, thereby enhancing the local suction of the roller core on the water-absorbing roller sleeve, and further increasing the suction of the water-absorbing roller sleeve on the aluminum foil. In this way, the aluminum foil can be tightly adsorbed on the surface of the water-absorbing roller sleeve of the water-absorbing pipe, so that the water-absorbing roller sleeve can absorb the water on the surface of the aluminum foil as cleanly as possible, and at the same time, the local suction of the roller core on the water-absorbing roller sleeve is enhanced, so that the wiping roller can absorb the water in the water-absorbing roller sleeve more cleanly, and further, the water-absorbing roller sleeve can absorb the water on the surface of the aluminum foil more cleanly.

[0015] Optionally, a flow guide portion is further provided on the sealing member, the flow guide portion is provided on the inner wall of the sealing member, and the flow guide portion is connected to the lower side of the water suction pipe.

[0016] By adopting this technical solution, the guide part arranged on the inner wall of the seal can play a guiding role when the roller core absorbs the water in the water-absorbing roller cover through the vent hole into the roller core and flows to the seal of the closing component, and gathers the water on the seal under the water absorption pipe. In this way, after the water absorption pipe is connected to the negative pressure air source, the water on the seal can be sucked away and discharged from the inside of the wiping roller in time.

[0017] Optionally, a water squeezing assembly corresponding to the wiping roller is further provided on the outside of the water-absorbing roller sleeve, the water squeezing assembly includes a pressure plate, a plurality of support frames and rings arranged in one-to-one correspondence with the support frames, the plurality of rings are fixedly connected to the roller shaft, the plurality of rings are respectively arranged on both sides of the roller core, the plurality of support frames fixedly connect the rings and the pressure plate, the pressure plate is arranged on the outside of the roller core and pressed on the water-absorbing roller sleeve, the extension direction of the pressure plate is parallel to the axial direction of the roller core, the front end of the pressure plate rotating along the roller core is far from the outer wall of the roller core, and the rear end of the pressure plate rotating along the roller core is close to the outer wall of the roller core.

[0018] By adopting this technical solution, the pressure plate of the water squeezing assembly is pressed on the water absorption roller sleeve. When the water absorption roller sleeve rotates with the roller core, the outer wall of the water absorption roller sleeve will contact the inner wall of the pressure plate and be squeezed by the pressure plate, and because the front end of the pressure plate rotating along the roller core is far away from the outer wall of the roller core, and the rear end of the pressure plate rotating along the roller core is close to the outer wall of the roller core, the water absorption roller sleeve will rotate with the rotation of the water absorption roller sleeve under the condition of being squeezed by the pressure plate. The distance between the pressure plate and the outer wall of the roller core will become smaller and smaller, and the water absorption roller sleeve will be squeezed more and more severely, so that the water in the water absorption roller sleeve will be squeezed more and more cleanly. In this way, the arrangement of the squeezing component can squeeze out the water in the water-absorbing roller sleeve when the wiping roller rotates, and cooperate with the negative pressure inside the wiping roller to absorb the water squeezed out of the water-absorbing roller sleeve into the inside of the wiping roller. Finally, as the suction pipe is drawn out of the wiping roller, the arrangement of the squeezing component can further squeeze out the water in the wiping roller core, and cooperate with the negative pressure inside the wiping roller to discharge the water in the water-absorbing roller sleeve more cleanly, thereby facilitating the water-absorbing roller sleeve to absorb the water on the surface of the aluminum foil more cleanly. At the same time, since the front end of the pressing plate is closer to the outer wall of the roller core, and the rear end of the pressing plate is farther from the outer wall of the roller core, when the pressing plate squeezes the water-absorbing roller sleeve, since the water-absorbing roller sleeve is squeezed more severely by the rear end of the pressing plate, most of the water in the water-absorbing roller sleeve will be squeezed and discharged toward the front end of the pressing plate, and very little will be discharged toward the rear end of the pressing plate, so that the water of the water-absorbing roller sleeve is discharged more cleanly after passing through the squeezing component, which is convenient for the water-absorbing roller sleeve to better absorb the water on the surface of the aluminum foil in the next cycle of rotation.

[0019] Optionally, the pressure plate is arranged between the aluminum foil and the suction roller sleeve, and a squeezing roller and a transmission roller are also arranged on the pressure plate. The squeezing roller is arranged on the end surface of the pressure plate in contact with the suction roller sleeve, and the transmission roller is arranged on the end surface of the pressure plate close to the aluminum foil.

[0020] By adopting this technical solution, the pressing plate is set at the position between the aluminum foil and the wiping roller, and after the water absorption roller sleeve absorbs the water on the aluminum foil surface, the pressing plate can squeeze the wiping roller to help the water absorption roller sleeve drain water, and then the water absorption roller sleeve that has drained water can perform a second water absorption and wiping on the aluminum foil surface; and the setting of the squeezing roller and the driving roller can convert the friction between the pressing plate and the water absorption roller sleeve and the friction between the pressing plate and the aluminum foil into roller friction, reducing the friction between the pressing plate and the water absorption roller sleeve and the aluminum foil. In this way, the pressing plate is set at the position between the aluminum foil and the wiping roller, and the water absorption roller sleeve can perform a second water absorption and wiping on the aluminum foil, further cleaning the aluminum foil surface; the squeezing roller can reduce the friction of the pressing plate on the water absorption roller sleeve, reduce the consumption of the water absorption roller sleeve, and extend the service life of the water absorption roller sleeve; the driving roller can reduce the friction of the pressing plate on the aluminum foil surface, prevent the aluminum foil surface from being scratched, and ensure the glossiness of the aluminum foil surface.

[0021] Optionally, a dust removal assembly is also provided on the outer circumferential surface of each of the water-absorbing roller sleeves, and the dust removal assembly includes a dust removal pipe and a dust suction nozzle, one end of the dust removal pipe is connected to a negative pressure air source, and the dust suction nozzle is arranged at the other end of the dust removal pipe, and the dust suction nozzle is arranged on the mounting frame, and the dust suction nozzle is arranged at a position corresponding to the closing assembly, and the dust suction nozzle abuts against the outer circumferential surface of the water-absorbing roller sleeve.

[0022] By adopting this technical solution, when the water suction roller sleeve absorbs water on the surface of the aluminum foil, since the roller core inside the water suction roller sleeve is connected to negative pressure, the water suction roller sleeve will absorb dust particles and other impurities on the surface of the aluminum foil on the surface of the water suction roller sleeve, and water will penetrate through the water suction roller sleeve under the attraction of negative pressure and flow into the roller core and be discharged along the water suction pipe, while dust particles and other impurities cannot pass through the water suction roller sleeve and can only adhere to the surface of the water suction roller sleeve. In this way, after the dust suction nozzle is connected to the negative pressure air source through the dust removal pipeline, suction will be generated at the dust suction nozzle. After the dust suction nozzle is set on the surface of the water suction roller sleeve and at the position corresponding to the closing component, the closing component will block the vents at the corresponding positions of the roller core and the dust suction nozzle. At this time, the dust suction nozzle can absorb dust particles and other impurities attached to the surface of the water suction roller sleeve, so that the surface of the water suction roller sleeve remains clean, and when the water suction roller sleeve rotates to the next position to clean the surface of the aluminum foil, the surface of the aluminum foil can be cleaned.

[0023] Optionally, the dust nozzle is further provided with a toggle part, which is elastically provided, one end of which is fixedly provided on the dust nozzle, and the other end of which is pressed on the outer circumferential surface of the water absorption roller sleeve.

[0024] By adopting this technical solution, when the water absorption roller sleeve rotates with the wiping roller, the outer wall of the water absorption roller sleeve will rub against the paddle. Since the paddle part is elastically arranged, when the paddle and the outer wall of the water absorption roller sleeve rub against each other, the paddle will scrape off the dust particles and other impurities attached to the outer wall of the water absorption roller sleeve, and the scraped dust particles will be sucked away by the dust suction nozzle. In this way, through the cooperation of the paddle and the dust suction nozzle, the dust particles attached to the surface of the water absorption roller sleeve that are difficult to be adsorbed by only can be scraped off and then sucked into the dust suction nozzle, so as to further clean the water absorption roller sleeve and ensure the cleanliness of the water absorption roller sleeve.

[0025] Optionally, the dust removal assembly also includes a dust cover, which is fixedly mounted on the mounting frame, the dust cover is arranged outside the wiping roller, the dust cover is provided with an inlet and an outlet, the aluminum foil is passed through the inlet and outlet of the dust cover, and the inlet and outlet of the dust cover are both provided with air ports, the air ports are connected to an external air source, and the air ports are arranged to align with the aluminum foil.

[0026] By adopting this technical solution, since the wiping roller is connected to a negative pressure air source, when the wiping roller absorbs and adsorbs water and dust particles on the surface of the aluminum foil, the dust in the surrounding air will also be adsorbed on the surface of the water-absorbing roller cover, which increases the workload of the dust suction nozzle, making it difficult for the dust suction nozzle to cleanly adsorb the dust on the surface of the water-absorbing roller cover. Installing a dust cover on the outside of the wiping roller can isolate the wiping roller and reduce the wiping roller from adsorbing dust particles in the environment on the surface of the water-absorbing roller cover, and the setting of the air outlet can prevent dust particles in the environment outside the dust cover from entering the inside of the dust cover along with the aluminum foil from the entrance and exit of the dust cover; at the same time, the setting of the air outlet can also purge the surface of the aluminum foil to reduce the adhesion of dust particles on the surface of the aluminum foil.

[0027] In summary, the present invention includes at least one of the following beneficial technical effects:

[0028] By providing a wiping roller with a negative pressure connection inside and a water-absorbing roller cover outside the wiping roller, the surface of the aluminum foil can be cleaned and the water on the surface of the aluminum foil can be absorbed. After the water-absorbing roller cover absorbs the water on the surface of the aluminum foil, the water inside the water-absorbing roller cover will be sucked into the inside of the wiping roller by the negative pressure inside the wiping roller, and discharged from the wiping roller along the water-absorbing pipe inside the wiping roller. In this way, the water inside the water-absorbing roller cover will not store much water, and the water on the surface of the aluminum foil can be absorbed for a long period of time, which saves the time of frequent replacement of the wiping roller and effectively improves the efficiency of the wiping roller in absorbing water on the surface of the aluminum foil.

[0029] A water squeezing component is also arranged on the outside of the wiping roller. The water squeezing component can further squeeze the water absorption roller cover on the basis of absorbing the water in the water absorption roller cover by the negative pressure inside the wiping roller. After squeezing out the water in the water absorption roller cover, the squeezed water is sucked into the inside of the wiping roller in cooperation with the negative pressure inside the wiping roller, so that the water in the water absorption roller cover is less, thereby enabling the wiping roller to absorb the water on the surface of the aluminum foil more cleanly.

[0030] A dust removal component is also provided on the outside of the water-absorbing roller cover. The dust cover in the dust removal component can isolate the wiping roller to reduce the wiping roller from adsorbing dust particles in the environment on the surface of the water-absorbing roller cover. The dust suction nozzle in the dust removal component can absorb dust particles and other impurities attached to the surface of the water-absorbing roller cover to keep the surface of the water-absorbing roller cover clean and reduce the dust particles attached to the surface of the aluminum foil.

DETAILED DESCRIPTION

[0039] The following combination Figures 1 to 7 The present invention is described in further detail.

[0040] The embodiment of the present invention discloses an aluminum foil cleaning device. Figure 1 to Figure 2 An aluminum foil cleaning device mainly comprises a conveying mechanism 1, a cleaning mechanism 2 for cleaning the surface of the aluminum foil, a wiping mechanism 3 for absorbing water on the surface of the aluminum foil, and a drying mechanism 4 for drying the surface of the aluminum foil, wherein the wiping mechanism 3 comprises a mounting frame 31, two wiping rollers 32 rotatably mounted on the mounting frame 31, a plurality of reversing rollers 33 fixedly mounted on the mounting frame 31, a water squeezing assembly 34 and a dust removal assembly 35 which are respectively arranged in a one-to-one correspondence with the wiping rollers 32, and the two wiping rollers 32 are respectively used for absorbing water on the two surfaces of the aluminum foil; when cleaning the aluminum foil, the aluminum foil is output from the conveying mechanism 1 and then enters the cleaning mechanism 2, and the aluminum foil is dried in the cleaning mechanism 2. The aluminum foil is washed with solution and water in the washing mechanism 2, and then output from the washing mechanism 2. The washed aluminum foil passes through the wiping mechanism 3; in the wiping mechanism 3, the aluminum foil first passes through the first wiping roller 32 to absorb water on one end surface of the aluminum foil, and then passes through multiple reversing rollers 33 to adjust the conveying direction of the aluminum foil. The aluminum foil passes through the second wiping roller 32 to absorb water on the other end surface of the aluminum foil. The wiping roller 32 will absorb and clean the water and dust attached to the surface of the aluminum foil, so that the surface of the aluminum foil remains clean as a whole. Finally, the aluminum foil passes through the drying mechanism 4 to perform the final drying treatment on the surface of the aluminum foil. The dried aluminum foil will be recovered to another conveying structure for the next step of processing.

[0041] See attached Figure 2 To Attachment Figure 4The wiping mechanism 3 includes a fixed mounting frame 31, on which two wiping rollers 32 and a plurality of reversing rollers 33 are mounted. The wiping roller 32 includes a roller shaft 321, a roller core 322, a water-absorbing roller sleeve 324, two sealing sleeves 323, a water-absorbing pipe 325 and a closing assembly 326. The mounting frame 31 is two fixed vertical plates, and the two ends of the roller shaft 321 are respectively fixedly connected to the two vertical plates of the mounting frame 31. The roller core 322 is a cylindrical structure, and covers are fixedly provided at both ends of the roller core 322, and the cover at one end of the roller core 322 is connected to the main body of the roller core 322 through a threaded structure. Circular mounting holes are respectively provided at the center positions of the covers at both ends of the roller core 322, and the outer circumferential surfaces of the two sealing sleeves 323 are respectively fixedly mounted on the roller core 322. In the mounting holes at both ends, the inner circumference of the sealing sleeve 323 is fixed on the outer circumference of the roller shaft 321, and a plurality of ventilation holes 3221 penetrating the roller core 322 are evenly provided on the circumference of the roller core 322. The water-absorbing roller sleeve 324 is a tubular structure made of sponge. In other embodiments, the water-absorbing roller sleeve 324 can also be various water-absorbing materials such as cotton cloth, water-absorbing fiber material, water-absorbing foam material or water-absorbing resin. The water-absorbing roller sleeve 324 is fixed to the outer wall of the roller core 322 by gluing. The roller shaft 321 is provided with a mounting hole for fixing and installing a water-absorbing pipe 325. One end of the water-absorbing pipe 325 is passed through the mounting hole on the roller shaft 321 and extends to the internal area of ​​the roller core 322. The other end of the water-absorbing pipe 325 is connected to the negative pressure air source outside the wiping roller 32.

[0042] See attached Figure 5 To Attachment Figure 6 The closing component 326 includes a fixing member 3261, a supporting member 3262 and a sealing member 3263. The fixing member 3261 is a semi-cylindrical structure mounted on the roller shaft 321. The fixing member 3261 is fixed to the roller shaft 321 by screws. The supporting member 3262 is a supporting rod fixedly arranged on the outer wall of the fixing member 3261. The sealing member 3263 is an arc-shaped structure and the arc of the arc structure is the same as the arc of the inside of the roller core 322. The other end of the supporting member 3262 is supported on the inner wall of the sealing member 3263. A rubber sealing layer is arranged on the outer wall of the sealing member 3263. The outer wall of the sealing member 3263 is tightly attached to the inner wall of the roller core 322. A plurality of guide grooves are arranged on the inner wall of the sealing member 3263. The plurality of guide grooves finally converge to the middle position of the sealing member 3263. The plurality of guide grooves jointly form a guide portion 3264 on the sealing member 3263. The suction pipe 325 is arranged above the position where the guide portion 3264 converges. In other embodiments, the closing component 326 can also be a cavity structure fixedly disposed on the roller shaft 321, the side wall of the cavity contacts the inner wall of the roller core 322, and a sealing strip structure is provided at the end where the cavity contacts the inner wall of the roller core 322, so that when the roller core 322 rotates relative to the cavity, the cavity can also block some of the air holes 3221 on the roller core 322.

[0043] See attached Figure 3 A gear structure is also provided on the side wall at one end of the roller core 322, and a driving device is also installed on the mounting frame 31 corresponding to the wiping roller 32. The driving device is a motor with a gear connected to the output shaft, and the gear on the motor is meshed with the gear structure on the roller core 322. In other embodiments, the driving device can also be a motor connected to a belt, chain, etc. that can drive the roller core 322 to rotate and a transmission structure with a power source.

[0044] When the motor drives the roller core 322 to rotate, the water suction pipe 325 is connected to the external negative pressure air source, the roller core 322 is in a negative pressure state, and the aluminum foil is attached to the water suction roller cover 324 outside the roller core 322 and rotates with the water suction roller cover 324. When the aluminum foil is attached to the outer wall of the water suction roller cover 324 for transportation, the aluminum foil will cover the water suction roller cover 324 on the upper half of the circumference of the water suction roller cover 324, and at this time, the closing component 326 will close and block the air holes 3221 in the lower half of the roller core 322, so that the air holes 3221 in the upper half of the roller core 322 can absorb the water suction roller cover 324, and the water suction roller cover 324 in contact with the aluminum foil in the upper half will absorb the water on the surface of the aluminum foil. The water in the water-absorbing roller sleeve 324 is lost and temporarily stored in the water-absorbing roller sleeve 324. Since the roller core 322 is connected to a negative pressure air source, the water in the water-absorbing roller sleeve 324 will be attracted by the negative pressure and continuously penetrate toward the roller core 322, and finally be attracted to the inside of the roller core 322, so that the water-absorbing roller sleeve 324 will not store much water. After the water is attracted to the inside of the roller core 322, it will flow along the inner wall of the roller core 322 to the inner wall of the seal 3263. A guide part 3264 is provided on the inner wall of the seal 3263. The guide part 3264 will guide the water on the inner wall of the seal 3263 to the bottom of the water-absorbing pipe 325, and finally the water will be discharged from the outside of the roller core 322 as the water-absorbing pipe 325 is sucked.

[0045] See attached Figure 5 To Attachment Figure 6The squeezing assembly 34 includes a pressing plate 341, a support frame 342, a collar 343, a squeezing roller 345 and a driving roller 344. Two collars 343 are provided. Both of the two collars 343 are two semi-annular structures fixed together by bolts. The collars 343 are fixed to the roller shaft 321 by screws, and the two collars 343 are fixed to the two sides of the wiping roller 32 respectively. The support frame 342 is correspondingly arranged with the collar 343 and fixedly arranged on the outer wall of the collar 343. The pressing plate 341 is fixedly installed on the other end of the supporting frame 342. The pressing plate 341 is arranged on the wiping roller 3 2, when the aluminum foil rotates with the absorbent roller sleeve 324, the aluminum foil will first adhere to the outer peripheral surface of the absorbent roller sleeve 324, and then the aluminum foil and the absorbent roller sleeve 324 will be separated by the pressing plate 341. After passing the position of the pressing plate 341, the aluminum foil will adhere to the surface of the absorbent roller sleeve 324 again. The extension direction of the pressing plate 341 is parallel to the axial direction of the roller core 322. The front end of the pressing plate 341 along the rotation direction of the roller core 322 is far from the outer wall of the roller core 322, and the rear end of the pressing plate 341 along the rotation direction of the roller core 322 is close to the outer wall of the roller core 322.

[0046] When the water-absorbing roller sleeve 324 passes through the water squeezing component 34, it will be compressed by the pressure plate 341 of the water squeezing component 34, and because the front end of the pressure plate 341 is closer to the outer wall of the roller core 322, and the rear end of the pressure plate 341 is farther from the outer wall of the roller core 322, when the pressure plate 341 squeezes the water-absorbing roller sleeve 324, the water in the water-absorbing roller sleeve 324 will be squeezed and discharged toward the front end of the pressure plate 341 when the pressure plate 341 squeezes the water-absorbing roller sleeve 324.

[0047] See attached Figure 5 To Attachment Figure 6 Two fixed plates are also provided on both sides of the pressing plate 341, and a water squeezing roller 345 and a driving roller 344 are provided between the two fixed plates. The water squeezing roller 345 is arranged between the pressing plate 341 and the water absorption roller sleeve 324, and the driving roller 344 is arranged between the pressing plate 341 and the aluminum foil. When the water absorption roller sleeve 324 and the aluminum foil slide on the two end surfaces of the pressing plate 341, the water squeezing roller 345 and the driving roller 344 can convert the sliding friction between the water absorption roller sleeve 324 and the aluminum foil relative to the pressing plate 341 into rolling friction. On the one hand, it can reduce the wear of the water absorption roller sleeve 324 and extend the service life of the water absorption roller sleeve 324. On the other hand, it can prevent the surface of the aluminum foil from being scratched, thereby improving the yield rate of the aluminum foil.

[0048] See attached Figure 3 and attached Figure 7The dust removal assembly 35 includes a dust cover 353, a dust suction nozzle 352 and a dust removal pipe 351. The dust cover 353 is fixedly installed on the mounting frame 31. The dust cover 353 is composed of an upper and lower cover shell. When installing, first fix the upper cover shell to the mounting frame 31 by screws. After the wiping roller 32 is fixedly installed, the aluminum foil is wrapped around the surface of the water suction pipe 325 and then the lower cover shell is fixed to the upper cover shell by screws. Two through holes are also provided between the upper cover shell and the lower cover shell, which are used as the inlet and outlet of the aluminum foil respectively. The two through holes of the dust cover 353 are Two air blowing ports 354 are also provided, and the air blowing ports 354 are connected to an external fan through a pipeline. When the fan is turned on, the two surfaces of the aluminum foil can be blown. The dust cover 353 can isolate the wiping roller 32, reduce the negative pressure inside the wiping roller 32, and absorb dust particles in the environment on the surface of the water-absorbing roller cover 324; the setting of the air blowing ports 354 can prevent dust particles in the external environment of the dust cover 353 from entering the dust cover 353 from the inlet and outlet of the dust cover 353 along with the aluminum foil; at the same time, the setting of the air blowing ports 354 can also blow the surface of the aluminum foil to reduce the adhesion of dust particles on the surface of the aluminum foil.

[0049] See attached Figure 7 The dust suction nozzle 352 and the dust removal pipe 351 are fixedly arranged inside the dust cover 353, one end of the dust removal pipe 351 is connected to the negative pressure air source, and the dust suction nozzle 352 is connected to the other end of the dust removal pipe 351, and the dust suction nozzle 352 is arranged at a lower position of the water suction roller sleeve 324, and the dust suction nozzle 352 is aligned with the outer wall of the water suction roller sleeve 324, and the dust suction nozzle 352 abuts against the outer peripheral surface of the water suction roller sleeve 324, and a toggle part 3521 is fixedly arranged at the end of the dust suction nozzle 352, and the toggle part 3521 is an elastic paddle with one end fixedly arranged on the dust suction nozzle 352, and the other end of the elastic paddle is pressed on the surface of the water suction roller sleeve 324.

[0050] When the wiping roller 32 rotates, when the water-absorbing roller sleeve 324 passes the position of the dust nozzle 352, the dust nozzle 352 is connected to the negative pressure air source through the dust removal pipe 351, and suction will be generated at the dust nozzle 352 to suck away the dust particles and other impurities attached to the surface of the water-absorbing roller sleeve 324; when the paddle and the outer wall of the water-absorbing roller sleeve 324 are rubbed against each other, the paddle will scratch the surface of the water-absorbing roller sleeve 324 due to its elastic setting, and the dust particles on the surface of the water-absorbing roller sleeve 324 will be scratched off, and the scratched dust will be sucked away by the dust nozzle 352, and the water-absorbing roller sleeve 324 will be further cleaned.

[0051] The implementation principle of the aluminum foil cleaning device of the embodiment of the present invention is as follows: during installation, one end of the roller core 322 is first fixed to the roller shaft 321 through the sealing sleeve 323, the closing component 326 is installed inside the roller core 322 through the fixing member 3261, and then the other end of the roller core 322 is fixedly connected to the roller core 322 through a thread, and then the position of the roller shaft 321 is adjusted to fix the roller shaft 321 and the roller core 322 together on the mounting frame 31, and then the driving device is installed on the mounting frame 31 and the gear on the driving device is adjusted to mesh with the gear on the roller core 322, and then the squeezing component 34 is fixed through the collar 343. The water-squeezing assembly 34 is fixed on the roller shaft 321 so that the pressure plate 341 on the water-squeezing assembly 34 can be squeezed on the water-absorbing roller sleeve 324. Finally, the aluminum foil is attached to the surface of the water-absorbing roller sleeve 324, and the dust cover 353 is fixedly set on the outer surface of the wiping roller 32 and the positions of the dust suction nozzle 352 and the air blowing port 354 are adjusted to complete the installation of a water-absorbing assembly. The reversing roller 33 and the driving device can be fixed to the appropriate position on the mounting frame 31 as needed; when working, the aluminum foil enters the dust cover 353 from the entrance of the dust cover 353, and the air blowing port 354 set at the entrance of the dust cover 353 first blows the surface of the aluminum foil. , then the aluminum foil is attached to the water-absorbing roller cover 324 from a horizontal position on one side of the water-absorbing roller cover 324, and leaves the water-absorbing roller cover 324 from a horizontal position on the other side of the water-absorbing roller cover 324. When the aluminum foil is attached to the water-absorbing roller cover 324, it is transported from the upper half of the water-absorbing roller cover 324, and passes through the pressing plate 341 of the water squeezing assembly 34 at a position just above the water-absorbing roller cover 324. During this process, the water-absorbing roller cover 324 first absorbs the water attached to the surface of the aluminum foil, and then the water-absorbing roller cover 324 squeezes the water in the water-absorbing roller cover 324 through the pressing plate 341 and is absorbed into the roller core 322, and then is squeezed and dehydrated. The water-absorbing roller cover 324 will absorb the water on the surface of the aluminum foil for the second time. After the second water absorption, the water-absorbing roller cover 324 will pass through the dust suction nozzle 352 below to adsorb and remove dust on the surface of the water-absorbing roller cover 324. Finally, the aluminum foil is output from the outlet of the dust cover 353, leaves the current wiping roller 32, and passes through the reversing roller 33 to the next wiping roller 32 to clean the other surface of the aluminum foil. After the water penetrates through the water-absorbing roller cover 324 and flows into the inside of the roller core 322, it will gather on the seal 3263 and be sucked away by the water-absorbing pipe 325 set above the seal 3263, and discharged from the wiping roller 32.

[0052] In summary, the embodiment of the present invention can absorb the water on the surface of the aluminum foil through the water-absorbing roller cover 324 by means of negative pressure suction, and at the same time, use negative pressure suction to absorb the water inside the water-absorbing roller cover 324 into the wiping roller 32, and discharge the water inside the wiping roller 32 through the water-absorbing pipe 325 inside the wiping roller 32, so that the water inside the water-absorbing roller cover 324 will not store much water, so that the water-absorbing roller cover 324 can absorb the water on the surface of the aluminum foil for a long period of time, saving the time of frequent replacement of the wiping roller 32, and improving the efficiency of the wiping roller 32 in absorbing water on the surface of the aluminum foil; a water squeezing component 34 is also provided on the outside of the wiping roller 32, which can squeeze the water-absorbing roller cover 324 to help The suction roller sleeve 324 is helped to drain water better, and at the same time, the suction roller sleeve 324 can absorb water from the surface of the aluminum foil for the second time, so that the water on the surface of the aluminum foil is absorbed more cleanly; a dust removal component 35 is also arranged on the outside of the suction roller sleeve 324, and the dust cover 353 in the dust removal component 35 can isolate the wiping roller 32 to reduce the dust particles in the environment adsorbed by the wiping roller 32 on the surface of the suction roller sleeve 324, and the dust suction nozzle 352 in the dust removal component 35 can absorb the dust particles and other impurities attached to the surface of the suction roller sleeve 324 to keep the surface of the suction roller sleeve 324 clean, and the air blowing port 354 in the dust removal component 35 can purge the surface of the aluminum foil to reduce the dust particles adhering to the surface of the aluminum foil.
