[0001] This utility model relates to the field of copper foil production technology, and in particular to a copper foil production air knife liquid cut-off device. Background Technology
[0002] Copper foil undergoes pickling, washing, and anti-oxidation processes during production to remove impurities from its surface and prevent oxidation. However, after passing through pickling solution tanks, washing solution tanks, and anti-oxidation solution tanks, the copper foil surface must be dried to prevent the solutions from previous processes from being carried into the next solution tank, thus ensuring the quality of copper foil production.
[0003] In existing technologies, air knives are generally used to blow air to achieve liquid-free drying of copper foil. However, the structure of such air knives is relatively simple and complex. The height and angle between the air knife and the copper foil cannot be adjusted according to actual needs. As a result, the liquid-free drying effect is not good when performing liquid-free drying on copper foils of different thicknesses and surface types, and it cannot meet the requirements for liquid-free drying of copper foil. Therefore, the existing air knife structure needs to be improved. Utility Model Content

[0023] Please see Figures 1 to 4 A copper foil production air knife liquid cutting device includes a mounting support 100 and a first air knife 200 and a second air knife 300 mounted on the mounting support 100. The first air knife 200 and the second air knife 300 are arranged vertically opposite each other after being mounted on the mounting support 100. The side wall of the mounting support 100 is provided with a vertical sliding groove 110. The side walls of the first air knife 200 and the second air knife 300 are respectively provided with adjusting screws 400. By passing the end of the adjusting screw 400 through the sliding groove 110 and connecting it with a fastener 500, the first air knife 200 and the second air knife 300 can be movably mounted on the mounting support 100.
[0024] Specifically, in this embodiment, there are two mounting supports 100, and adjusting screws 400 are respectively provided on the side walls of the first air knife 200 and the second air knife 300. A sliding groove 110 is formed on the side wall of the mounting support 100. The adjusting screws 400 are passed through the sliding groove 110 and connected with fasteners 500, so that the first air knife 200 and the second air knife 300 are mounted vertically on the two sets of mounting supports 100. When it is necessary to adjust the height and angle of the first air knife 200 and the second air knife 300, the fasteners 500 can be loosened. At this time, the adjusting screws 400 can move up and down within the sliding groove 110, thereby adjusting the vertical position of the first air knife 200 and the second air knife 300. The spacing between the air knife 200 and the upper surface of the conveyed copper foil is matched, and the spacing between the second air knife 300 and the lower surface of the conveyed copper foil is matched. At the same time, when the fastener 500 is loosened, the adjusting screw 400 can be rotated, thereby adjusting the vertical angle of the first air knife 200 and the second air knife 300. This allows for better matching of the angle of the air blown by the first air knife 200 and the second air knife 300 with the conveyed copper foil, ensuring the effective drying of the upper and lower surfaces of the copper foil. Furthermore, the use of the sliding groove 110, the adjusting screw 400, and the fastener 500 simplifies the adjustment structure of the first air knife 200 and the second air knife 300, making vertical and angle adjustments more convenient and quick.
[0025] To simplify the overall structure of the air knife liquid cut-off device, in this embodiment, one end of the adjusting screw 400 is welded to the side wall of the first air knife 200 and the side wall of the second air knife 300. The end of the adjusting screw 400 that passes through the sliding groove 110 is threaded, and the fastener 500 is a nut. The fastener 500 and the end of the adjusting screw 400 can be threaded together. The first air knife 200 and the second air knife 300 can be fixed by the threaded connection, and the height and angle of the first air knife 200 and the second air knife 300 can be easily adjusted.
[0026] In addition, to make the first air knife 200 and the second air knife 300 more stable when mounted on the mounting support 100, a shim 600 is also fitted at the end of the adjusting screw 400 that passes through the sliding groove 110. The shim is located between the fastener 500 and the side wall of the sliding groove 110. The shim 600 can make the first air knife 200 and the second air knife 300 more secure after installation to prevent loosening. At the same time, it can also reduce the wear between the fastener 500 and the side wall of the sliding groove 110, effectively improving the overall service life of the air knife liquid cut-off device.
[0027] In order to make the overall structure of the air knife liquid cut-off device more stable, the mounting support 100 in this embodiment is triangular in shape. The triangular mounting support 100 makes the overall structure of the first air knife 200 and the second air knife 300 more stable after they are installed on the mounting support 100.
[0028] Please see Figure 1 and Figure 2 To ensure the effectiveness of the air knife in cutting off the liquid, the first air knife 200 in this embodiment has a hollow internal structure, forming a first air cavity. An upper air inlet 210 communicating with the first air cavity is provided at the top of the first air knife 200, and an upper air outlet 220 communicating with the first air cavity is provided at the bottom of the first air knife 200. At the same time, the second air knife 300 has a hollow internal structure, forming a second air cavity. A lower air outlet 310 communicating with the second air cavity is provided at the top of the second air knife 300, and a lower air inlet 320 communicating with the second air cavity is provided at the bottom of the second air knife 300. Both the upper air outlet 220 and the lower air outlet 310 are rectangular structures, and the outlet width of both the upper air outlet 220 and the lower air outlet 310 is 0.1mm-0.3mm.
[0029] The upper surface of the copper foil is dried by blowing air through the first air knife 200, and the lower surface of the copper foil is dried by blowing air through the second air knife 300. Air is introduced through the upper air inlet 210 and the lower air inlet 320 and directed to the first and second air chambers. The air from the first air chamber is then blown onto the upper surface of the copper foil through the upper air outlet 220, and the air from the second air chamber is blown onto the lower surface of the copper foil through the lower air outlet 310. This achieves liquid-free drying of both the upper and lower surfaces of the copper foil. The rectangular design of the upper air outlet 220 and the lower air outlet 310, with a width of 0.1mm-0.3mm, allows the blown air to better match the surface of the copper foil, ensuring the liquid-free drying effect and preventing the previous solution from being carried into the next solution tank.
[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description; however, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model; furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
