Description

Technical Field

[0001] This utility model relates to the field of aluminum foil processing technology, specifically to an aluminum foil processing water washing device. Background Technology

[0002] In aluminum foil processing, surface cleanliness is one of the key factors affecting product quality. During rolling, cutting, coating, and other processes, oil, metal particles, oxide layers, or other impurities easily adhere to the surface of aluminum foil. These contaminants not only affect the appearance quality of the aluminum foil but also reduce its subsequent processing performance (such as coating adhesion, printing quality, and capacitor performance). Therefore, efficient and thorough cleaning of aluminum foil is an indispensable and important step in aluminum foil processing.

[0003] Traditional aluminum foil cleaning methods often employ either water washing or chemical cleaning, which suffer from low cleaning efficiency and incomplete cleaning. For example, water washing alone is insufficient to remove stubborn oil stains and oxide layers, while chemical cleaning, although effective in removing contaminants, may introduce new chemical residues. Furthermore, traditional cleaning equipment often uses fixed spraying or immersion methods, which are difficult to adapt to the cleaning needs of aluminum foils of different thicknesses and materials. In addition, the drying efficiency after cleaning is low, which can easily lead to water stains or oxidation on the aluminum foil surface. Therefore, we need to propose an aluminum foil processing water washing device. Utility Model Content

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.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0027] The interior of the washing tank 1 is divided by a partition to form a pre-washing tank 2, a rinsing tank 3 and a rinsing tank 4. The aluminum foil passes through the interior of the pre-washing tank 2, the rinsing tank 3 and the rinsing tank 4 in sequence by the guiding component. The aluminum foil is simultaneously blown on both sides by the drying component and the surface moisture is quickly removed and dried by the high-speed airflow.

[0028] Two sets of ultrasonic generators 7 are symmetrically fixedly installed on one side wall of the pre-washing tank 2, and two sets of ultrasonic transducers 8 electrically connected to the ultrasonic generators 7 are installed through the corresponding position on the other side wall.

The ultrasonic generator 7 is a Hangzhou Chenggong Ultrasonic JY-2000W, with a frequency of 40kHz and a power of 1000W / unit, supporting frequency adjustment from 20-50kHz. The ultrasonic transducer 8 is a Hangzhou Chenggong Ultrasonic CS-40A, with a frequency of 40kHz and a power of 500W, using PZT-4 piezoelectric ceramics and a waterproof rating of IP68.

[0030] In an optional embodiment: the rinsing mechanism 9 includes a conveying pipe 91, an external connecting pipe 92, a spray pipe 93, and rinsing nozzles 94. The conveying pipe 91 is installed through one side wall of the rinsing tank 3. The inlet of the conveying pipe 91 is fixedly connected to the external connecting pipe 92. Both outlets of the conveying pipe 91 are fixedly connected to the spray pipe 93. Several sets of equidistantly arranged rinsing nozzles 94 are fixedly connected to the spray pipe 93.

[0031] It should be noted that the delivery pipe 91 and the external pipe 92 are made of DN50 stainless steel pipe. The external pipe 92 is connected to the water supply equipment. The spray pipe 93 is made of DN32 stainless steel pipe with a wall thickness of 2mm. The rinsing nozzle 94 is a fan-shaped nozzle of the spray system SS-1 / 4GG-SS12015 with a spray angle of 120°, a flow rate of 15L / min, and a working pressure of 0.3-0.5MPa. The low-pressure design avoids deformation of the aluminum foil.

[0032] In an optional embodiment: the two sets of spray pipes 93 are arranged vertically and vertically, and the water outlet direction of the rinsing nozzles 94 is towards the aluminum foil surface.

[0033] It should be noted that the water supply equipment is connected through the external pipe 92, and the liquid is sent into the two sets of spray pipes 93 through the delivery pipe 91. The spray pipes 93 arranged symmetrically above and below and multiple sets of rinsing nozzles 94 are used to perform high-pressure rinsing on both sides of the aluminum foil, which can quickly wash away the contaminants remaining after pre-washing, avoid secondary pollution, and ensure surface cleanliness.

[0034] In an optional embodiment: the drying assembly includes a drying shell 11, a limiting conveying roller 12 for limiting and conveying aluminum foil, and an air knife 13 for drying aluminum foil. The drying shell 11 is fixedly installed at one end of the washing tank 1 by a support frame. Three sets of limiting conveying rollers 12 for conveying aluminum foil are installed at equal intervals inside the drying shell 11. Air knives 13 are fixedly installed on both the upper and lower sides of the aluminum foil inside the drying shell 11.

[0035] It should be noted that the drying shell 11 adopts a double-layer insulation structure, with an inner layer of 304 stainless steel and an outer layer of carbon steel, and 50mm thick rock wool filling the middle. The air knife 13 is a Shanghai air knife AS-600, with a length of 600mm, an air outlet gap of 0.5mm, and is made of 304 stainless steel.

[0036] In an optional embodiment: each set of limiting conveying rollers 12 consists of two sets of upper and lower corresponding rollers for guiding aluminum foil conveying, and the two sets of air knives 13 are installed at an angle, and the air inlet pipe of the air knife 13 passes through the drying shell 11 and is connected to a high-pressure air source.

[0037] It should be noted that the air knives 13 installed at an angle inside the drying assembly blow the aluminum foil on both sides simultaneously, using high-speed airflow to quickly remove surface moisture, avoiding water stains or oxidation spots caused by natural drying. Multiple sets of limiting conveyor rollers 12 form a stable conveying path, ensuring that the aluminum foil remains flat during the drying process and reducing surface scratches or deformation caused by shaking or uneven tension.

[0038] In an optional embodiment: the conveying assembly includes four sets of inlet conveying rollers 5 rotatably mounted at equal intervals on the top of the washing tank 1, three sets of immersion conveying rollers 6 rotatably mounted inside the pre-wash tank 2 and the rinsing tank 4, and two sets of spray conveying rollers 10 rotatably mounted inside the rinsing tank 3.

[0039] It should be noted that the inlet guide roller 5, the liquid-immersed guide roller 6, and the spray guide roller 10 are all made of rubber or have a surface coating to avoid scratching the aluminum foil surface. The combined design of the inlet guide roller 5, the liquid-immersed guide roller 6, and the spray guide roller 10 can adapt to the conveying needs of aluminum foil of different thicknesses.

[0040] In an optional embodiment: the three sets of immersion guide rollers 6 inside the pre-wash tank 2 and the rinsing tank 4 are arranged in an equilateral triangle, and the two sets of spray guide rollers 10 inside the rinsing tank 3 are arranged in parallel.

[0041] It should be noted that the three sets of immersion guide rollers 6 are arranged in an equilateral triangle to increase the time the aluminum foil spends in the pre-wash tank 2 and the rinsing tank 4, and the two sets of spray guide rollers 10 are arranged in parallel to provide rinsing space for the rinsing mechanism 9.

[0042] In an optional embodiment: a drain pipe 14 is installed through one side of the bottom of the pre-wash tank 2, the rinsing tank 3 and the rinsing tank 4, and a solenoid valve is provided on the outer wall of the drain pipe 14.

[0043] It should be noted that each tank is equipped with a drain pipe 14 and a solenoid valve at the bottom, which can discharge cleaning waste liquid in stages, facilitating subsequent classification and treatment or recycling, and reducing water waste and chemical pollution.

[0044] Working principle: When using this utility model, aluminum foil is fed into the pre-washing tank 2, rinsing tank 3 and rinsing tank 4 in sequence by the foil feeding machine, inlet guide roller 5, immersion guide roller 6 and spray guide roller 10. The ultrasonic generator 7 generates a high-frequency electrical signal (frequency 20-40kHz) and transmits it to the ultrasonic transducer 8. The transducer converts the electrical signal into mechanical vibration. The vibration is transmitted to the surface of the aluminum foil through the pre-washing liquid (such as alkaline cleaning agent or pure water), forming a cavitation effect. Millions of tiny bubbles are generated in the liquid. When the bubbles burst, they release shock waves (pressure up to 1000 atmospheres), peeling off oil, metal particles and oxide layer.

[0045] Three sets of immersion guide rollers 6 in the pre-wash tank ensure that the aluminum foil is completely immersed in the pre-wash solution, with a contact time of 3-5 seconds, improving cleaning efficiency. The external pipe 92 in the rinsing mechanism 9 in the rinsing tank 3 is connected to the water supply equipment to transport the cleaning solution to the conveying pipe 91. The conveying pipe 91 transports the liquid to the upper and lower sets of spray pipes 93. Each spray pipe is equidistantly arranged with rinsing nozzles 94 (nozzle spacing 50-100mm). The water outlet direction of the nozzles is at an angle of 30°-45° to the surface of the aluminum foil. High-pressure water flow (flow velocity 5-10m / s) impacts both sides of the aluminum foil, rinsing away the contaminants remaining after pre-washing. Pure water (conductivity ≤5μS / cm) is used in the rinsing tank 4 for final cleaning to remove residual cleaning agent or ions on the surface of the aluminum foil. The three sets of immersion guide rollers 6 extend the residence time of the aluminum foil in pure water (5-8 seconds) to ensure thorough cleaning.

[0046] The drying shell 11 contains three sets of limiting conveying rollers 12, the roller surfaces of which are covered with polyurethane or silicone material to avoid scratching the aluminum foil and conveying the aluminum foil. The air knife 13 installed on the upper and lower sides of the aluminum foil has an air inlet pipe connected to a high-pressure air source (pressure 0.4~0.6MPa). The compressed air is accelerated to 100~200m / s through a slit (width 0.1~0.2mm). The air knife is installed at an angle (15°~30° with the aluminum foil surface) to form a laminar airflow and quickly peel off the moisture from the aluminum foil surface.

[0047] The control method described in this application involves automatic control via a controller, which employs a Siemens S7-1200 PLC (CPU1215CDC / DC / DC) paired with a 7-inch Weintek MT8071 iE touchscreen. The controller's control circuitry can be easily implemented by those skilled in the art through simple programming and is considered common knowledge in the field. Furthermore, since this application primarily focuses on protecting the structure, shape, and their connections, the control method and circuit connections will not be explained in detail here.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
