Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0024] Please see Figure 1-5 This embodiment provides the following technical solution: an aluminum foil electrolytic corrosion device, including a processing box 1, a conveying channel for the aluminum foil body to pass through, a feeding double roller 104 on the right side of the processing box 1, and a discharging double roller 105 on the left side of the processing box 1. The feeding double roller 104 and the discharging double roller 105 enable the aluminum foil body to be conveyed on the processing box 1.

[0025] The processing box 1 is provided with a corrosion chamber 101, a cleaning chamber 102 and a drying chamber 103. Multiple guide rollers are rotatably connected in the corrosion chamber 101, the cleaning chamber 102 and the drying chamber 103. In some embodiments, the guide rollers in the corrosion chamber 101, the cleaning chamber 102 and the drying chamber 103 are arranged in an S-shape.

[0026] The corrosion chamber 101 is equipped with a corrosion liquid spraying mechanism 2, which includes two first spray plates 201. The two first spray plates 201 are respectively disposed on both sides of the aluminum foil body. Each of the two first spray plates 201 is provided with a first spray group 202 facing the aluminum foil body. In some embodiments, the two first spray plates 201 are disposed on the upper and lower sides of the aluminum foil body. Through the first spray plates 201 and the first spray group 202, under the operation of the liquid supply equipment, the first spray group 202 sprays the surface of the aluminum foil body that it passes through, thereby corroding the aluminum foil body.

[0027] The cleaning chamber 102 is equipped with a cleaning liquid spraying mechanism 3, which includes two second spray plates 301. The two second spray plates 301 are respectively disposed on both sides of the aluminum foil body. Each of the two second spray plates 301 is provided with a second spray group 302 facing the aluminum foil body. In some embodiments, the two second spray plates 301 are respectively disposed on the upper and lower sides of the aluminum foil body. Through the second spray plates 301 and the second spray group 302, under the operation of the liquid supply equipment, the second spray group 302 sprays the surface of the aluminum foil body, thereby cleaning the surface of the aluminum foil body.

[0028] In some embodiments, the drying chamber 103 is equipped with a dryer to further clean the surface of the aluminum foil body.

[0029] Both the corrosion chamber 101 and the cleaning chamber 102 are equipped with a scraping mechanism 4. Each scraping mechanism 4 includes two scraping blades 401, which are respectively located on the left and right sides of the aluminum foil body. The ends of the scraping blades 401 are rotatably connected to a support frame 402 that is fixedly connected to the processing box 1. An elastic element is also provided between the scraping blades 401 and the support frame 402. Through the scraping blades 401 and the elastic element, the liquid adsorbed on both sides of the aluminum foil can be scraped off during the process of removing the aluminum foil from the corrosion chamber 101 and the cleaning chamber 102, which improves the processing effect on both sides of the aluminum foil and also avoids the liquid remaining on the surface of the aluminum foil from affecting the subsequent processing of the aluminum foil.

[0030] In some embodiments, the two scraper blades 401 in the corrosion chamber 101 and the cleaning chamber 102 are both arranged in an inverted V shape, and absorbent cotton can also be provided on the surface of the scraper blades 401 to further improve the scraping effect on the surface of the aluminum foil body and also to avoid the scraper blades 401 from damaging the aluminum foil body.

[0031] The elastic element includes a fixed cylinder 403, a telescopic cylinder 405, and a buffer spring 406. One end of the fixed cylinder 403 is hinged to a connecting plate 404 that is fixedly connected to the support frame 402. The telescopic cylinder 405 is slidably connected inside the fixed cylinder 403. One end of the telescopic cylinder 405 extends through the outside of the fixed cylinder 403 and is hinged to the wiper blade 401. The buffer spring 406 is sleeved on the outside of the fixed cylinder 403. Both ends of the buffer spring 406 are fixedly connected to the ends of the fixed cylinder 403 and the telescopic cylinder 405, respectively. Through the fixed cylinder 403, the telescopic cylinder 405, and the buffer spring 406, the wiping end of the wiper blade 401 can always be in contact with the surface of the aluminum foil body, thereby improving the wiping effect of the wiper blade 401.

[0032] The working principle of this utility model is as follows: During the conveying process of the aluminum foil body, the liquid supply device on the corrosion chamber 101 is activated through the control system, so that the corrosion liquid enters the first spray plate 201. The first spray group 202 can spray corrosion on the surface of the aluminum foil body. Before the aluminum foil body enters the cleaning chamber 102, the scraper plates 401 on the left and right sides can scrape off the residual corrosion liquid on the surface of the aluminum foil body, and then the aluminum foil body enters the cleaning chamber 102.

[0033] Then, the liquid supply device in the cleaning chamber 102 is activated so that the cleaning liquid enters the second spray plate 301. The second spray group 302 can spray and clean the surface of the aluminum foil body. Before the aluminum foil body enters the drying chamber 103, the scraper plates 401 on the left and right sides can scrape off the residual cleaning liquid on the surface of the aluminum foil body, and then allow the aluminum foil body to enter the drying chamber 103.

[0034] Finally, the dryer in the drying chamber 103 is started to dry the aluminum foil body. The dried aluminum foil body is then removed from the processing box 1.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
