Description

Technical Field

[0001] The invention relates to the field of aluminum material cleaning, in particular to a device for cleaning oil stains on the surface of an aluminum coil. Background Art

[0002] Aluminum coil is a metal material, mainly made of aluminum or aluminum alloy. It is a coil with a certain width and thickness formed by multiple processes such as hot rolling, cold rolling, and drawing. During the production and transportation of aluminum coils, due to various factors such as lubricating grease during processing, handling or storage, unclean gloves of operators, oil leakage of equipment, etc., the coils will be stained with some oil stains, affecting subsequent transportation and processing. Therefore, some equipment and devices are needed to clean the oil stains on the surface of aluminum coils.

[0003] At present, a Chinese patent application with publication number CN215031678U and publication date December 7, 2021 proposes a cleaning pool for cleaning oil stains on the surface of aluminum materials, including a cleaning pool, a feed pipe and a discharge pipe. The cleaning pool is also provided with a loading assembly, and the loading assembly includes a shell and a screw rod. The screw rod is arranged in the cleaning pool, and one end of the screw rod is fixedly connected to a movable rod. The other end of the movable rod passes through the cleaning pool and one side of the shell and is connected to a driven gear. A motor and a driving gear are provided in the shell, and the driving gear is connected to the driven gear through a rack. A slider is also provided on the screw rod, and a loading mesh frame is fixedly connected to the outer side of the slider. A flushing assembly matching the loading mesh frame is provided on the outer side of the cleaning pool.

[0004] When in use, first inject external cleaning solution into the cleaning pool through the feed pipe, then pile the aluminum material in the loading screen frame, and start the motor to move the loading screen frame to the inside of the cleaning pool. When the aluminum material in the loading screen frame is completely submerged in the solution surface in the cleaning pool, the motor can be turned off, and external ultrasonic equipment can be used to facilitate the feeding and taking of materials when cleaning the aluminum material. When the aluminum material is cleaned, start the motor again, the motor will drive the active gear to rotate in the opposite direction, and the loading screen frame will rise upward. When the aluminum material is completely out of the cleaning pool, use the flushing component to flush the aluminum material for the second time, and finally flip the closed door to take the aluminum material out of the loading screen frame to complete the cleaning of the aluminum material.

[0005] With regard to the above-mentioned related technologies, after the aluminum coil is immersed in a cleaning tank for degreasing, a large amount of cleaning liquid will adhere to the surface of the aluminum coil when it comes out of the cleaning tank. Subsequently, a large amount of clean water is needed to rinse off the cleaning liquid adhered to the surface of the aluminum coil, which wastes water resources. Summary of the invention

[0006] In order to reduce the water resources required for flushing the cleaning liquid attached to the surface of the aluminum coil during the water washing stage, the present invention provides an aluminum coil surface oil stain cleaning device.

[0007] The present invention provides a device for cleaning oil stains on the surface of an aluminum coil, which adopts the following technical solution:

[0008] A device for cleaning oil stains on the surface of an aluminum coil comprises an unwinding mechanism, a solvent cleaning mechanism, a water washing mechanism, a drying mechanism and a winding mechanism which are sequentially arranged along the conveying direction of the aluminum coil;

[0009] The solvent cleaning mechanism comprises a cleaning pool, a first power roller and a first transmission roller respectively arranged on both sides of the cleaning pool, a reversing roller arranged inside the cleaning pool, and an air blowing assembly arranged on the cleaning pool, wherein the first power roller and the first transmission roller are arranged above the cleaning pool, the reversing roller is immersed in the cleaning liquid in the cleaning pool, and the first power roller, the first transmission roller and the reversing roller are all rotatably arranged on the cleaning pool;

[0010] The air blowing assembly includes a lifting frame, an inner baffle and an outer baffle fixedly mounted on the lifting frame, the first power roller is mounted above the lifting frame, the inner baffle and the outer baffle are arranged on both sides of the aluminum coil, an upper air blow is mounted on the inner baffle, and a lower air blow is mounted on the outer baffle, the upper air blow and the lower air blow are both connected to an external air source, the upper air blow and the lower air blow are arranged opposite to each other, and the upper air blow and the lower air blow are both arranged opposite to the direction of conveying the aluminum coil.

[0011] By adopting this technical solution, the unwinding mechanism conveys the aluminum coil backward by rotating, and the aluminum coil passes through the first transmission roller installed on one side of the cleaning pool and is immersed in the cleaning liquid in the cleaning pool, and is reversingly driven by the reversing roller in the cleaning liquid. After coming out of the cleaning liquid, the aluminum coil is conveyed upward to the first power roller on the other side of the cleaning pool, and the aluminum coil is blown on both sides by upper air blowing and lower air blowing in the process of being conveyed to the first power roller by the reversing roller. The upper air blowing and the lower air blowing are arranged relative to the conveying direction of the aluminum coil, so as to blow off the cleaning liquid attached to the surface of the aluminum coil, and reduce the cleaning liquid attached to the surface of the aluminum coil in the process of conveying the aluminum coil backward after coming out of the cleaning liquid. During the blowing process, the inner baffle and the outer baffle will play an isolation effect, and reduce the splashing of the cleaning liquid after being blown away by the upper air blowing and the lower air blowing, thereby polluting the surrounding environment. In this way, the lifting frame can lift the first power roller to a position above the cleaning liquid, so that the aluminum coil can be purged by the upper air blow and the lower air blow during the upward conveying process, and the setting of the upper air blow and the lower air blow can reduce the cleaning liquid attached to the surface of the aluminum coil when the aluminum coil is conveyed out of the solvent cleaning mechanism, so that the aluminum coil does not need to consume a large amount of water resources to rinse the surface of the aluminum coil when passing through the water washing stage, thereby saving water resources, and using air blowing to blow the purging liquid on the aluminum coil can avoid direct contact between the parts and the cleaning liquid attached to the aluminum coil, reduce the probability of the parts being contaminated or corroded by the cleaning liquid, and extend the service life of the parts; and the setting of the inner baffle and the outer baffle can reduce the splashing of the cleaning liquid in the environment when the upper air blow and the lower air blow disperse the cleaning liquid on the surface of the aluminum coil, thereby reducing pollution to the surrounding environment.

[0012] Optionally, two quick-release assemblies are also provided on the air blowing assembly, and mounting openings are provided on the inner baffle plate and the outer baffle plate, and the two quick-release assemblies are respectively installed in the mounting openings of the inner baffle plate and the outer baffle plate, and the quick-release assembly includes a mounting part, a rotating part and a blocking part, and the mounting part is arranged corresponding to the mounting opening, the rotating part is rotatably installed on the mounting part, and the blocking part is fixedly installed on one end of the rotating part, and a handle is fixedly installed on the other end of the rotating part, and the blocking part abuts against the mounting opening after the rotating part rotates.

[0013] By adopting this technical solution, when installing the quick-release assembly, first install the mounting part in the mounting openings of the corresponding inner baffle and outer baffle, then turn the handle on the mounting part, the handle will drive the rotating part and the blocking part to rotate together, and the blocking part will be against the inner wall of the mounting opening after rotating with the rotating part, thereby fixing the mounting part on the mounting opening. In this way, when the upper air blower and the lower air blower fail or need maintenance, there is no need to remove the inner baffle and the outer baffle from the cleaning pool together. You only need to turn the handle to quickly connect the upper air blower and the lower air blower to the inner baffle or the outer baffle to fix or remove it, making it more convenient to install the upper air blower and the lower air blower, simplifying the installation process and improving maintenance efficiency.

[0014] Optionally, the quick-release assembly also includes a plurality of quick-release connectors, and the plurality of quick-release connectors are installed on an end face of the mounting member on which the blocking member is provided, and the air inlets of the plurality of quick-release connectors are all connected to an external air source, and the upper air blow and the lower air blow are respectively connected to the air outlets of the plurality of quick-release connectors.

[0015] By adopting this technical solution, the upper air blow and the lower air blow are connected with a quick-release connector, and the quick-release connector and the installation connector are used together. When replacing the upper air blow or the lower air blow, first turn the handle to remove the installation part. After replacing the air blow through the quick-release connector, place the installation part inside the installation port. Turn the handle to fix the installation part to complete the entire replacement process, which further simplifies the replacement operation of the upper air blow and the lower air blow. When the first power roller of the oil stain cleaning device rotates slowly, the upper air blow or the lower air blow can be replaced without stopping the machine, thereby further improving work efficiency.

[0016] Optionally, an isolation component is also fixedly arranged inside the cleaning pool, and the isolation component includes a guide piece and an isolation piece, both of which are fixedly arranged on the inner wall of the cleaning pool, the guide piece and the isolation piece are both arranged in a funnel shape, the end of the guide piece with a larger opening is arranged in a direction away from the air blowing component, the end of the guide piece with a smaller opening is arranged below the air blowing component, the end of the isolation piece with a larger opening is arranged in the direction of the air blowing component, the end of the guide piece with a larger opening is connected to the end of the isolation piece with a larger opening, and the end of the isolation piece with a smaller opening is immersed in the cleaning liquid, the end of the guide piece with a smaller opening and the end of the isolation piece with a smaller opening are both provided with through holes, and the aluminum coil passes through the through holes provided on the end of the guide piece with a smaller opening and the end of the isolation piece with a smaller opening.

[0017] By adopting this technical solution, when the aluminum coil comes out of the cleaning liquid in the cleaning pool, it will pass through the end of the smaller opening of the isolation piece and come out of the cleaning liquid from the side of the larger opening of the isolation piece; when the air blowing component blows the aluminum coil, the cleaning liquid and oil stains attached to the surface of the aluminum coil will be blown off and flow along the outer wall of the guide piece into the cleaning liquid on the outside of the larger opening of the isolation piece. In this way, after the aluminum coil is immersed in the cleaning liquid, the oil stains attached to the surface of the aluminum coil will fall off in the cleaning liquid and float above the cleaning liquid. The setting of the isolation member can isolate most of the oil stains in the area outside the isolation member, reduce the oil stains floating on the surface of the cleaning liquid attached to the surface of the aluminum coil when it comes out of the cleaning liquid, and reduce the probability that the air blowing component will have difficulty in blowing away the oil stains attached to the surface of the aluminum coil. The setting of the guide member can play a guiding role when the blowing component blows the surface of the aluminum coil, and guide the cleaning liquid or stains attached to the surface of the aluminum coil to the area outside the isolation member when it is blown off, reducing the probability that the aluminum coil will pick up the oil stains again when it comes out of the cleaning liquid in the internal area of ​​the isolation member after the oil stains fall into the internal area of ​​the isolation member, so that the aluminum coil has only the cleaning liquid attached to the surface as much as possible when passing through the air blowing component, ensuring that the air blowing component can blow the surface of the aluminum coil as clean as possible.

[0018] Optionally, rib plates are provided on both sides of the elevated frame, and the rib plates fixedly connect the elevated frame and the cleaning pool.

[0019] By adopting this technical solution, the aluminum coil has a certain tension when being transported between the first power roller and the first transmission roller. When the lifting frame is directly fixed on the side wall of the cleaning pool, the lifting frame will form a bending force in the lateral direction when it is subjected to the tension and gravity of the aluminum coil, making the support of the lifting frame unstable. The setting of the rib plate can make the lifting frame, the rib plate and the side of the cleaning pool form a triangular stable structure, thereby increasing the stability of the lifting frame.

[0020] Optionally, the water washing mechanism includes a water washing hood, a second transmission roller, a second power roller, an upper nozzle, a lower nozzle and a circulation pump, an inlet and an outlet are respectively provided on two opposite sides of the water washing hood, the second transmission roller is rotatably installed at the inlet of the water washing hood, the second power roller is rotatably installed at the outlet of the water washing hood, the upper nozzle and the lower nozzle are respectively arranged on the upper and lower sides of the outlet, the upper nozzle and the lower nozzle are relatively arranged inside the water washing hood, the upper nozzle and the lower nozzle are connected to the water outlet of the circulation pump, and the water inlet of the circulation pump is connected to a clean water source.

[0021] By adopting this technical solution, the aluminum coil enters the water washing hood through the inlet of the water washing hood and is supported on the second transmission roller for transportation. The second power roller at the other end of the water washing hood provides pulling force to drive the aluminum coil. When the aluminum coil moves between the second transmission roller and the second power roller, the upper nozzle and the lower nozzle will wash the upper and lower surfaces of the aluminum coil under the action of the circulation pump. Such aluminum coil cleaning liquid is generally a component soluble in water. The upper and lower nozzles are used to wash the upper and lower surfaces of the aluminum coil to wash away the cleaning liquid attached to the surface of the aluminum coil. When the surface of the aluminum coil is washed in a non-contact manner, the probability of causing slip marks on the surface of the aluminum coil can be reduced, thereby improving the yield rate of the aluminum coil.

[0022] Optionally, the water washing mechanism also includes a scraper assembly, which is arranged on one side of the upper nozzle and the lower nozzle close to the outlet of the water washing hood, and the scraper assembly includes an upper scraper, a lower scraper and two side scrapers, and the upper scraper, the lower scraper and the two side scrapers are all fixedly arranged on the water washing hood, the upper scraper and the lower scraper are respectively abutted against the upper and lower end surfaces of the aluminum coil, and the two side scrapers are respectively abutted against the two side edges of the aluminum coil.

[0023] By adopting this technical solution, the upper scraper and the lower scraper can scrape off the water attached to the surface of the aluminum coil after the aluminum coil is washed by the upper nozzle and the lower nozzle, and the side scraper can scrape off the water attached to the side of the aluminum coil, so that there is no obvious water stain attached to the surface of the aluminum coil after the aluminum coil is transported out of the water washing cover through the second power roller. In this way, the upper scraper, the lower scraper and the side scraper can preliminarily dry the surface of the aluminum coil after the aluminum coil is washed, so that the aluminum coil can be quickly dried after entering the drying mechanism, reducing the energy consumed by the drying mechanism when drying the aluminum coil, and saving energy.

[0024] Optionally, the extension direction of the upper scraper is arranged at an acute angle to the conveying direction of the aluminum coil.

[0025] By adopting this technical solution, the inclined setting of the upper scraper can scrape off the water stains attached to the upper surface of the aluminum coil and play a diversion role at the same time, draining the water scraped from the upper surface of the aluminum coil to the edge of the aluminum coil, reducing the gathering of the scraped water on the upper surface of the aluminum coil, so that the upper scraper can clean the water on the surface of the aluminum coil more cleanly.

[0026] Optionally, the water washing mechanism is further provided with a guide groove and a wastewater treatment tank, the guide groove is arranged at the bottom of the water washing cover, and the water outlet of the guide groove is connected to the water inlet of the wastewater treatment tank.

[0027] By adopting this technical solution, after the water washing mechanism uses clean water to rinse the aluminum coil that has been immersed in the cleaning liquid, the cleaning liquid attached to the aluminum coil will be dissolved in the clean water, causing the clean water to be contaminated by the cleaning liquid. The setting of the guide trough and the wastewater treatment tank can uniformly recycle the contaminated clean water into the wastewater treatment tank for treatment, thereby reducing the probability of wastewater contaminated by the cleaning liquid polluting the environment.

[0028] Optionally, a filter assembly and a circulation pipeline are also connected to the wastewater treatment tank, the water outlet of the wastewater treatment tank is connected to the water inlet of the filter assembly, and the water outlet of the filter assembly is connected to a clean water source through the circulation pipeline.

[0029] By adopting this technical solution, the wastewater in the wastewater treatment tank is filtered by the filter assembly and then connected to the clean water source through the circulation pipeline, and is transported to the water washing mechanism together with the clean water source to wash the aluminum coil again. In this way, the wastewater in the wastewater treatment tank can be recycled and reused, reducing the total water consumption of the water washing mechanism when washing the aluminum coil, and saving water resources.

[0030] In summary, the present invention includes at least one of the following beneficial technical effects:

[0031] By arranging upper air blowing and lower air blowing on the solvent cleaning mechanism, the cleaning liquid attached to the surface of the aluminum coil when the aluminum coil is output from the solvent cleaning mechanism can be reduced, and the water resources consumed when the cleaning agent attached to the surface of the aluminum coil is washed during the water washing stage can be reduced; the cleaning agent attached to the surface of the aluminum coil is purged by a non-contact method such as air blowing, which can avoid direct contact between parts and the cleaning liquid when removing the cleaning liquid attached to the aluminum coil, reduce the probability of parts being contaminated or corroded by the cleaning liquid, and extend the service life of the parts.

[0032] The arrangement of the inner baffles and the outer baffles around the upper air blow and the lower air blow can reduce the splashing of the cleaning liquid into the surrounding environment when the upper air blow and the lower air blow disperse the cleaning liquid on the surface of the aluminum coil, thereby reducing the pollution to the surrounding environment.

[0033] The setting of the isolation component can isolate most of the oil stains in the area outside the guide and the isolation component, reducing the oil stains floating on the surface of the cleaning liquid attached to the surface of the aluminum coil when it comes out of the cleaning liquid. At the same time, it plays a guiding role when cooperating with the air blowing component to blow the surface of the aluminum coil, reducing the oil stains falling on the internal area of ​​the isolation component, and ensuring that the air blowing component can blow the surface of the aluminum coil as clean as possible.

[0034] The setting of mounting parts and quick-release joints simplifies the installation process of upper and lower air blowers and improves maintenance efficiency.

[0035] By setting up the scraper assembly, the upper scraper, the lower scraper and the side scraper can scrape off the water stains attached to the surface of the aluminum coil after the aluminum coil is washed, reducing the water stains attached to the surface of the aluminum coil entering the drying mechanism, reducing the energy consumed by the drying mechanism when drying the aluminum coil, and saving energy.

[0047] The following combination Figures 1 to 10 The present invention is described in further detail.

[0048] Embodiment 1: The embodiment of the present invention discloses a device for cleaning oil stains on the surface of an aluminum coil. Figure 1 A device for cleaning oil stains on the surface of an aluminum coil comprises an unwinding mechanism 1, a solvent cleaning mechanism 2 for cleaning the aluminum coil with a solvent, a water washing mechanism 3 for washing the aluminum coil with water, a drying mechanism 4 for drying the aluminum coil, and a rewinding mechanism 5 which are arranged in sequence.

[0049] Refer to the attached Figure 2 To Attachment Figure 4 The solvent cleaning mechanism 2 includes a cleaning pool 21, a first transmission roller 22 and a first power roller 23 respectively arranged on the side walls at both ends of the cleaning pool 21, and a reversing roller 24 arranged inside the cleaning pool 21. A cylindrical mounting hole is arranged on the side wall at one end of the cleaning pool 21, and the first transmission roller 22 is installed in the mounting hole. The fixed shaft of the reversing roller 24 is fixedly arranged on the inner wall of the cleaning pool 21, and the reversing roller 24 is rotatably arranged on the fixed shaft. An elevated frame 251 is arranged on the side wall at the other end of the cleaning pool 21, and a mounting hole is also arranged on the elevated frame 251. The first power roller 23 is rotatably installed in the mounting hole on the elevated frame 251, and the rotating shaft of the first power roller 23 passes through the mounting hole and is connected with the output shaft of the motor.

[0050] In this way, the cleaning pool 21 is also filled with cleaning liquid. In this embodiment, the cleaning liquid uses an aluminum surface degreasing and oil-removing cleaning agent. The aluminum coil is input from the first transmission roller 22, enters the solvent cleaning mechanism 2, and is immersed in the cleaning liquid for immersion after passing through the first transmission roller 22. During the immersion in the cleaning liquid, the aluminum coil is adjusted by the reversing roller 24 and transported in the direction of the first power roller 23, and is output from the solvent cleaning mechanism 2 after passing through the first power roller 23.

[0051] Refer to the attached Figure 2 To Attachment Figure 4 An inner baffle plate 252 and an outer baffle plate 253 are also provided on the lifting frame 251. The inner baffle plate 252 and the outer baffle plate 253 are respectively arranged on both sides of the first power roller 23. An upper air blow 254 is fixedly installed on the side wall of the inner baffle plate 252 close to the outer baffle plate 253, and a lower air blow 255 is fixedly installed on the side wall of the outer baffle plate 253 close to the inner baffle plate 252. The upper air blow 254 and the lower air blow 255 are both high-pressure air nozzles connected to the air source, and the nozzle shape of the air nozzle is a straight opening. The upper air blow 254 and the lower air blow 255 are both aimed at the surface of the aluminum coil, and the upper air blow 254 and the lower air blow 255 form a certain angle with the conveying direction of the aluminum coil and are opposite to the conveying direction of the aluminum coil.

[0052] In this way, when the aluminum coil comes out of the cleaning liquid after passing through the reversing roller 24 and is transported to the first power roller 23, after the upper air blow 254 and the lower air blow 255 are turned on, the upper air blow 254 and the lower air blow 255 will respectively blow the two surfaces of the aluminum coil in the direction of the aluminum coil conveying, and blow off the cleaning liquid attached to the surface of the aluminum coil after it comes out of the cleaning liquid, which can reduce the corrosion of the cleaning liquid attached to the surface of the aluminum coil to the subsequent objects in contact with the surface of the aluminum coil, and at the same time, it can also reduce the consumption of the cleaning liquid on the surface of the aluminum coil by the subsequent water washing mechanism 3. In order to save water resources, air blowing is used to remove the cleaning liquid attached to the surface of the aluminum coil. Compared with the scraper structure, it can also avoid direct contact with the cleaning liquid, and reduce the corrosion of the scraper assembly 37 caused by direct contact; when the upper air blow 254 and the lower air blow 255 are used to blow the cleaning liquid attached to the surface of the aluminum coil, the inner baffle 252 and the outer baffle 253 can play an isolation role, and the splashing cleaning liquid blown away by the upper air blow 254 and the lower air blow 255 is blocked between the inner baffle 252 and the outer baffle 253, thereby reducing the splashing of the cleaning liquid into the surrounding environment and reducing the pollution to the surrounding environment.

[0053] In the first embodiment of the present invention, the implementation principle of an aluminum coil surface oil stain cleaning device is as follows: after the aluminum coil is output by the unwinding mechanism 1, it passes through the first transmission roller 22 and enters the cleaning pool 21 of the solvent cleaning mechanism 2, and the aluminum coil passes through the connection between the first transmission roller 22 and the reversing roller 24 to be immersed in the aluminum surface degreasing and degreasing cleaning agent in the cleaning pool 21 for degreasing, and then the aluminum coil passes through the connection between the reversing roller 24 and the first power roller 23 and comes out of the cleaning liquid to be transported upward. During the upward transportation process, the aluminum coil passes through the inner baffle 252 and the outer baffle 253 installed on the lifting frame 251, and the inner baffle 252 and the outer baffle 253 are fixedly installed. The upper air blow 254 and the lower air blow 255 will respectively purge the cleaning liquid attached to the surface of the aluminum coil, reduce the adhesion of the cleaning liquid on the surface of the aluminum coil, reduce the corrosion of the cleaning liquid attached to the surface of the aluminum coil to the subsequent objects in contact with the aluminum coil (such as the first power roller 23 and the structure supporting the aluminum material on the water washing mechanism 3), and reduce the water resources required for the water washing mechanism 3 to wash away the washing liquid on the surface of the aluminum coil; at the same time, the inner baffle 252 and the outer baffle 253 will block the splashing cleaning liquid blown away by the upper air blow 254 and the lower air blow 255 between the inner baffle 252 and the outer baffle 253, reducing pollution to the surrounding environment.

[0054] Embodiment 2: Based on Embodiment 1, refer to the attached Figure 3 To Attachment Figure 6 Two trapezoidal ribs 2511 are respectively fixed on the two sides of the lifting frame 251 by bolts, and the ribs 2511 connect the lifting frame 251 and the two sides of the cleaning pool 21. The inner baffle 252 and the outer baffle 253 fixedly installed on the lifting frame 251 by bolts are both provided with mounting openings 2561, and quick-release components 256 are correspondingly provided on the two mounting openings 2561. The quick-release components 256 include mounting parts 2562, rotating parts 2563 and blocking parts 2564. The mounting opening 2561 is a rectangular through opening, and the outer contour of the mounting part 2562 is a rectangular contour corresponding to the mounting opening 2561. A circular mounting hole is provided in the middle area of ​​the mounting part 2562, and the rotating part 2563 is installed in The cylindrical structure in the mounting hole in the middle of the mounting member 2562, the blocking member 2564 is a rectangular structure fixedly arranged at one end of the rotating member 2563, the length of the blocking member 2564 is between the width of the mounting member 2562 and the length of the mounting member 2562, the width of the blocking member 2564 is smaller than the width of the mounting member 2562, and a handle is also arranged at the other end of the mounting member 2562. Two quick connectors 2565 are also fixedly arranged on the mounting member 2562, and the block connectors all adopt self-locking pneumatic quick connectors. The two quick connectors 2565 are respectively arranged on both sides of the rotating member 2563, and the steam inlets of the two quick connectors 2565 are connected to the air source, and the upper air blow 254 and the lower air blow 255 are connected to the air outlets of the corresponding quick connectors 2565.

[0055] In other embodiments, the mounting opening 2561 and the mounting member 2562 may also be corresponding non-circular structures such as ellipses or polygons, the blocking member 2564 is a structure with length and width, and the length of the blocking member 2564 is between the longest distance between any two points symmetrical about the center of gravity on the edge line of the mounting member 2562 and the minimum distance between any two points symmetrical about the center of gravity on the edge line.

[0056] In this way, the upper air blower 254 and the lower air blower 255 are respectively installed on the quick-release connectors 2565 corresponding to the quick-release assembly 256, and then the mounting parts 2562 are respectively installed in the mounting openings 2561 corresponding to the inner baffle plate 252 and the outer baffle plate 253. By rotating the rotating part 2563 rotatably installed on the mounting part 2562 by the handle, the rotating part 2563 will drive the blocking part 2564 to rotate together, and the longer edge of the blocking part 2564 rotates beyond the edge of the mounting part 2562 and abuts against the inner wall of the mounting opening 2561, thereby completing the fixation of the positions of the mounting part 2562, the upper air blower 254 and the lower air blower 255; when disassembling, the longer edge of the blocking part 2564 can be retracted to the inner side of the edge of the mounting part 2562 by rotating the handle in the opposite direction, thereby canceling the fixation of the mounting part 2562 on the mounting opening 2561. When the upper air blower 254 or the lower air blower 255 needs maintenance or replacement, the upper air blower 254 or the lower air blower 255 can be quickly disassembled or installed through the cooperation of the quick-release assembly 256 and the quick-release connector 2565, which greatly improves the disassembly and assembly efficiency and saves the time required for maintenance and replacement of the air blow assembly.

[0057] Refer to the attached Figure 3 and attached Figure 7 An isolation assembly 26 is also provided on the inner wall of the cleaning pool 21. The isolation assembly 26 includes a guide 261 and an isolation 262. The guide 261 and the isolation 262 are both funnel-shaped. The guide 261 and the isolation 262 are fixed to the inner wall of the cleaning pool 21 by bolts installed on the side wall. The opening of the guide 261 is set in a direction away from the air blowing assembly 25, and the isolation 262 is set in a direction toward the air blowing assembly 25. The side with a larger opening of the guide 261 and the side with a larger opening of the isolation 262 are both provided with a protruding connection portion and are fixed by bolts. The guide piece 261 and the isolating piece 262 are connected together, and the smaller opening ends of the guide piece 261 and the isolating piece 262 are both provided with through holes. The isolating piece 262 is completely immersed in the cleaning liquid. After the guide piece 261 and the isolating piece 262 are connected together, the surface of the cleaning liquid is divided into an area between the guide piece 261 and the isolating piece 262, and an area outside the guide piece 261 and the isolating piece 262. The aluminum coil passes through the through hole at the bottom of the isolating piece 262 and passes through the area between the guide piece 261 and the isolating piece 262, and then passes through the through hole at the top of the guide piece 261 to be connected to the first power roller 23.

[0058] In this way, the setting of the isolation member 262 can isolate most of the oil stains in the area outside the guide member 261 and the isolation member 262, reduce the oil stains floating on the surface of the cleaning liquid that the aluminum coil is carrying when passing through the area inside the isolation member 262 when coming out of the cleaning liquid, and reduce the probability that the air blowing component 25 has difficulty in blowing away the oil stains attached to the surface of the aluminum coil. The setting of the guide member 261 can play a guiding role when the air blowing component 25 blows the surface of the aluminum coil, and guide the cleaning liquid or stains attached to the surface of the aluminum coil to the area outside the isolation member 262 when they are blown off, reducing the probability that the aluminum coil will be carrying the oil stains again when it comes out of the cleaning liquid in the internal area of ​​the isolation member 262 after the oil stains fall into the internal area of ​​the isolation member 262, so that the aluminum coil has only the cleaning liquid attached to the surface as much as possible when passing through the air blowing component 25, ensuring that the air blowing component 25 can blow the surface of the aluminum coil as clean as possible.

[0059] Refer to the attached Figure 8 To Attachment Fig. 9 The water washing mechanism 3 includes a water washing cover 31, a second transmission roller 32, a second power roller 33, a circulation pump 34, an upper nozzle 35 and a lower nozzle 36. The water washing cover 31 includes an upper cover shell and a lower cover shell connected by screws. The second transmission roller 32 includes two rotating rollers rotatably arranged on the upper cover shell and the lower cover shell respectively. The second power roller 33 includes two rotating rollers connected to a motor and rotatably arranged on the upper cover shell and the lower cover shell respectively. The upper nozzle 35 and the lower nozzle 36 are respectively arranged on the upper cover shell and the lower cover shell. The raw nozzle and the lower nozzle 36 are arranged on the second transmission roller. Between the driving roller 32 and the second power roller 33, the upper nozzle 35 and the lower nozzle 36 are connected to the water outlet of the circulation pump 34, and the water inlet of the circulation pump 34 is connected to the clean water. After the aluminum coil is output by the water washing mechanism 3, it enters the water washing mechanism 3 through the second driving roller 32. The upper nozzle 35 and the lower nozzle 36 arranged on the upper cover shell and the lower cover shell of the water washing mechanism 3 will respectively wash the upper and lower surfaces of the aluminum coil, and wash away the cleaning liquid remaining on the surface of the aluminum coil after the surface of the aluminum coil is blown by the upper air blow 254 and the lower air blow 255.

[0060] Refer to the attached Fig.10The water washing mechanism 3 further includes a scraper assembly 37, which includes an upper scraper 371, a lower scraper 372 and two side scrapers 373. The upper scraper 371 is fixedly arranged on the upper cover shell by a connecting column, and the bottom edge of the upper scraper 371 abuts against the upper surface of the aluminum coil. The lower scraper 372 is fixedly arranged on the lower cover shell by a connecting column, and the top edge of the lower scraper 372 abuts against the lower surface of the aluminum coil. The extension direction of the upper scraper 371 is set at an acute angle to the conveying direction of the aluminum coil. When the upper scraper 371 scrapes off the water stains on the upper surface of the aluminum coil, It can also play a diversion role, diverting the water on the upper surface of the aluminum coil along the inclined direction of the upper scraper 371 to the edge of the aluminum coil, which can reduce the accumulation of water on the upper surface of the aluminum coil, so that the upper scraper 371 can scrape the water stains on the upper surface of the aluminum coil more cleanly, and the lower scraper 372 can scrape the water stains on the lower surface of the aluminum coil. The two side scrapers 373 are respectively fixed between the upper cover shell and the lower cover shell through connecting columns. The edges of the side scrapers 373 are in contact with the two side edges of the aluminum coil, so as to scrape off the water stains attached to the sides of the aluminum coil.

[0061] In this way, after the aluminum coil is transported into the water washing mechanism 3 by the second transmission roller 32, the upper nozzle 35 and the lower nozzle 36 will respectively use clean water to wash the upper and lower surfaces of the aluminum coil, and the upper scraper 371, the lower scraper 372 and the two side scrapers 373 can respectively scrape off the water stains attached to the upper and lower surfaces and the two sides of the aluminum coil after washing, thereby reducing the water stains attached to the surface of the aluminum coil when it is output from the water washing mechanism 3, so that the aluminum coil will not be attached with more water stains during the subsequent drying process, which is convenient for the subsequent drying process of the aluminum coil and reduces the energy required for drying the water stains attached to the surface of the aluminum coil.

[0062] Refer to the attached Figure 7 To Attachment Fig. 9 The water washing mechanism 3 is also provided with a recovery component 38, which includes a guide groove 381 arranged on the lower cover shell of the water washing cover 31 and a wastewater treatment box 382 arranged below the water washing cover 31. The guide groove 381 is a through slot opened on the lower cover shell of the water washing cover 31, and both sides of the guide groove 381 are guide plates arranged obliquely. An opening is arranged above the wastewater treatment box 382, ​​and the opening arranged above the wastewater treatment box 382 is connected to the guide groove 381. A water outlet is arranged at the bottom of the wastewater treatment box 382, ​​and the water outlet is connected to a filter component 383. The filter component 383 generally adopts industrial wastewater treatment equipment. After the wastewater in the wastewater tank is treated by the filter component 383, it is transported to the circulating pump 34 through the circulating pipeline 384 again to wash the aluminum coil out of the team.

[0063] In this way, after the waste water from washing the aluminum coil is recovered through the waste water treatment box 382, ​​the recovered waste water is treated again through the filter component 383 and the circulation pipeline 384 for reuse, thereby reducing the total amount of water resources consumed in washing the aluminum coil and saving water resources.

[0064] Embodiment 2 of the present invention is a device for cleaning oil stains on the surface of an aluminum coil. The implementation principle is as follows: before use, the lifting frame 251 is first fixedly installed in the cleaning pool 21 through the rib plate 2511 and bolts, and then the inner baffle plate 252 and the outer baffle plate 253 are fixedly installed on the lifting frame 251 through bolts, and the isolation component 26 is fixed to the inner wall of the cleaning pool 21 through bolts, and finally the upper air blow 254 and the lower air blow 255 are installed on the corresponding mounting parts 2562 through the quick-release connector 2565, and the mounting parts 2562 are correspondingly installed in the mounting openings 2561 of the inner baffle plate 252 and the outer baffle plate 253, and the rotating The handle is moved to make the blocking member 2564 abut against the inner wall of the installation opening 2561, completing the fixing of the installation member 2562; when in use, the aluminum coil is conveyed backward through the unwinding mechanism 1, and during conveying, the aluminum coil first passes through the first transmission roller 22 on the cleaning pool 21, and then is immersed in the cleaning liquid in the cleaning pool 21 for immersion. After the conveying direction of the aluminum coil is adjusted by the reversing roller 24 in the cleaning liquid, the aluminum coil passes through the isolation member 262 and the guide member 261 in turn, and floats out of the cleaning liquid from the area between the guide member 261 and the isolation member 262. The aluminum coil passes through the mounting rack area and passes between the inner baffle plate 252 and the outer baffle plate 253. The upper air blow 254 and the lower air blow 255 provided on the inner baffle plate 252 and the outer baffle plate 253 will blow the two sides of the aluminum coil to blow off the cleaning liquid attached to the surface of the aluminum coil. The clean liquid blown off flows along the outer wall of the guide member 261 to the area outside the guide member 261 and the isolation member 262. Then, the aluminum coil passes through the first power roller 23 and is output and is transported to the water washing mechanism 3 through the second transmission roller 32. In the water washing hood 31, the upper nozzle 35 and the lower nozzle 36 will wash the upper and lower surfaces of the aluminum coil, and further wash away the cleaning liquid attached to the aluminum coil. After the washing is completed, the upper scraper 371, the lower scraper 372 and the two side scrapers 373 will remove the water stains attached to the surface of the aluminum coil after washing, thereby reducing the water stains attached to the surface of the aluminum coil. Finally, the aluminum coil is output through the second power roller 33 on the water washing mechanism 3, and finally, after being dried by the drying mechanism 4, it is taken up by the winding mechanism 5, completing the entire process of cleaning the oil stains on the surface of the aluminum coil.

[0065] In summary, the upper air blowing 254 and the lower air blowing 255 in the embodiment of the present invention can reduce the cleaning liquid attached to the surface of the aluminum coil when the aluminum coil is transported out of the solvent cleaning mechanism 2, so that the aluminum coil does not need to consume a large amount of water resources to rinse the surface of the aluminum coil when passing through the water washing stage, thereby saving water resources. In addition, the use of air blowing to purge the rinsing liquid on the aluminum coil can avoid direct contact between the parts and the cleaning liquid attached to the aluminum coil, thereby reducing the probability of the parts being contaminated or corroded by the cleaning liquid and extending the service life of the parts. The arrangement of the inner baffle 252 and the outer baffle 253 can reduce the splashing of the cleaning liquid in the environment when the upper air blowing 254 and the lower air blowing 255 disperse the cleaning liquid on the surface of the aluminum coil, thereby reducing the impact on the surrounding Environmental pollution; the setting of the quick-release component 256 simplifies the installation process of the upper air blow 254 and the lower air blow 255, improves the maintenance efficiency of the upper air blow 254 and the lower air blow 255, and saves time; the upper nozzle 35 and the lower nozzle 36 can wash the surface of the aluminum coil, and the scraper component 37 can preliminarily dry the surface of the aluminum coil, so that the aluminum coil can be quickly dried after entering the drying mechanism 4, reducing the energy consumed by the drying mechanism 4 when drying the aluminum coil; the wastewater treatment box 382, ​​the filter component 383 and the circulation pipeline 384 can cooperate to recycle the wastewater in the wastewater treatment box 382, ​​reduce the total water resource consumption when the water washing mechanism 3 washes the aluminum coil, and save water resources.

[0066] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
