Description

Technical Field

[0001] This utility model relates to the field of sheet metal anodizing technology, specifically to a horizontal conveying device for isolating the conductive tank and the oxidation tank in coil anodizing. Background Technology

[0002] In modern industrial production, anodizing generates a hard and dense oxide film on the surface of aluminum, which significantly improves the wear resistance and corrosion resistance of aluminum products. However, in actual industrial production, the thickness and length of aluminum plates pose various challenges, especially since the size of electrolytic cells and processing equipment is limited. The anodizing process of aluminum plates often requires dividing the plates into pieces for processing. Although this solves the problem of equipment size limitations to some extent, it leads to discontinuity in production.

[0003] Furthermore, in the existing technology, there is no water-blocking device between two adjacent tanks, and the liquid between the two adjacent tanks can easily flow between them. During the aluminum plate anodizing process, the electrolyte in the anodizing tank needs to be kept pure in order to reduce the impact of impurities on anodizing.

[0004] For example, patent application number 201821414778.7, published on April 5, 2019, discloses an automated production device for horizontal conveying of aluminum plates in anodizing. This automated production device for horizontal conveying of aluminum plates in anodizing includes: a main body box; an oil removal box, the top and bottom of which are fixed between the top and bottom of the inner wall of the main body box, and an oil remover is fixedly connected to the top of the inner wall of the oil removal box; and a first cleaning box. This utility model provides an automated production device for horizontal conveying of aluminum plates in anodizing, which allows for rational and standardized operation within different boxes. Due to its high level of automation, the entire production device effectively reduces the labor intensity of workers, avoids harm to workers from strong acids, strong alkalis, and exhaust gases, and reduces the defect rate caused by human factors through automated production. It improves the efficiency of anodizing production using aluminum plates and reduces the impact of human factors on production, making it highly practical.

[0005] In the above literature, the aluminum plate is inserted from the left side of the main box. As the plate moves, it sequentially enters the degreasing box, the first cleaning box, and the oxidation box. An oxide film is formed inside the oxidation box. Then, it enters the second cleaning box for secondary cleaning and other processes before finally being removed from the main box. However, in the above literature, there is a cavity between the oxidation box and the adjacent first and second cleaning boxes. There is no water-blocking device in the cavity. The liquid in the cleaning box can easily cross-contaminate with the liquid in the oxidation box. On the one hand, when liquid cross-contamination occurs, the anodic charge on the surface of the aluminum plate will be conducted through the cross-contaminated liquid, thus reducing the anodic charge on the aluminum plate itself and affecting the oxidation effect on the aluminum plate surface. On the other hand, because of the liquid cross-contamination, the liquid in the oxidation box will also be affected, which will also affect the oxidation effect on the aluminum plate surface. Summary of the Invention

[0006] This invention provides a horizontal conveying device for isolating the conductive tank and the oxidation tank in the anodizing of coiled material. With the structure of this invention, when the coiled material is horizontally conveyed through the conductive tank and the oxidation tank, liquid cross-contamination between the conductive tank and the oxidation tank can be effectively avoided, thereby improving the oxidation effect.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows: a horizontal conveying device for isolating the conductive tank and the oxidation tank in coil anodizing, comprising a tank body device, wherein the tank body device includes a conductive tank and an oxidation tank, which are arranged sequentially in the horizontal direction; a first channel is provided on the side of the conductive tank near the oxidation tank, and a second channel is provided on the side of the oxidation tank near the conductive tank; a first water-pressing roller mechanism is provided outside the first channel, the first water-pressing roller mechanism including one or more sets of first water-pressing rollers, each set including two first water-pressing rollers arranged vertically, with a first conveying channel between the two first water-pressing rollers in the first water-pressing roller set; a second water-pressing roller mechanism is provided outside the second channel, the second water-pressing roller mechanism including one or more sets of second water-pressing rollers, each set including two second water-pressing rollers arranged vertically, with a second conveying channel between the two second water-pressing rollers in the second water-pressing roller set; the first conveying channel and the second conveying channel are arranged horizontally.

[0008] Before use, the above setup involves injecting a liquid such as electrolyte into the conductive tank and the oxidation tank, ensuring that the liquid level is higher than the first and second channels. Then, the unwound roll is sequentially passed through the conductive tank, the first channel, the first conveying channel, the second conveying channel, the second channel, and the oxidation tank. During this process, the liquid in the conductive tank imparts an anodic charge to the unwound roll, while the oxidation tank provides a cathodic charge, thereby oxidizing the surface of the unwound roll within the oxidation tank. In this invention, during the process of the unwound material entering the oxidation tank from the conductive tank, the liquid level is higher than both the first and second channels. Therefore, the liquid in the conductive tank flows out through the first channel, and the liquid in the oxidation tank flows out through the second channel. However, in this invention, by setting up a first pressure roller group and a second pressure roller group, the first pressure roller group partially blocks the liquid flowing out of the first channel, and the second pressure roller group partially blocks the liquid flowing out of the second channel. This effectively prevents liquid crosstalk between the conductive tank and the oxidation tank, and prevents the anodic electricity from being partially transferred through the crosstalked liquid. This allows the anodic electricity to be transferred from the unwound material itself into the oxidation tank. Therefore, the unwound material can be better oxidized in the oxidation tank, thereby improving the oxidation effect.

[0009] Furthermore, the first pressure roller in the first pressure roller group near the conductive groove has a gap n1 between it and the outer wall of the conductive groove, and the second pressure roller in the second pressure roller group near the oxidation groove has a gap m1 between it and the outer wall of the oxidation groove. By setting gaps n1 and m1, direct contact and friction between the first pressure roller and the conductive groove, and direct contact and friction between the second pressure roller and the oxidation groove can be avoided, facilitating the smooth transport of the unwound roll.

[0010] Furthermore, the first water-pressing roller assembly comprises two sets: one set is positioned near the conductive tank, and the other set is positioned between the first water-pressing roller assembly near the conductive tank and the second water-pressing roller mechanism, with a first gap between the two sets of first water-pressing roller assemblies. Similarly, the second water-pressing roller assembly comprises two sets: one set is positioned near the oxidation tank, and the other set is positioned between the second water-pressing roller assembly near the oxidation tank and the first water-pressing roller mechanism, with a second gap between the two sets of second water-pressing roller assemblies. This structure, through the initial water-pressing barrier provided by the first water-pressing roller assembly near the conductive tank, minimizes the amount of liquid entering the space between the two sets of first water-pressing roller assemblies. The second set of first water-pressing roller assemblies then provides a secondary water-pressing barrier, allowing the liquid to flow out through the first gap between the two sets of first water-pressing roller assemblies. Similarly, by using the second set of pressure rollers near the oxidation tank for initial pressure blocking, less liquid enters the space between the two sets of second pressure rollers. Then, another set of second pressure rollers applies secondary pressure blocking, allowing the liquid to flow out through the first gap between the two sets of second pressure rollers. This improves the isolation of liquid between the conductive tank and the oxidation tank during the conveying and unwinding of the rolled material.

[0011] Furthermore, a first drain channel connected to the conductive groove is provided outside the first water-pressing roller mechanism, and a third channel is provided on the side of the first drain channel near the oxidation tank. A second drain channel connected to the conductive groove is provided outside the second water-pressing roller mechanism, and a fourth channel is provided on the side of the second drain channel near the conductive groove. This structure, by providing the first and second drain channels, allows liquid flowing from the conductive groove to enter the first drain channel, and liquid flowing from the oxidation tank to enter the second drain channel, thus further isolating the liquid between the conductive groove and the oxidation tank.

[0012] Furthermore, a first replenishment channel is provided on the conductive tank, and a first discharge channel is provided on the first discharge tank; a second replenishment channel is provided on the oxidation tank, and a second discharge channel is provided on the second discharge tank. In this structure, since the liquid level in the conductive tank is higher than the first channel, and the liquid level in the oxidation tank is higher than the second channel, some liquid in the conductive tank will inevitably flow out through the first channel, and some liquid in the oxidation tank will inevitably flow out through the second channel. Therefore, to ensure the liquid levels in the conductive tank and the oxidation tank are maintained, a first replenishment channel and a second replenishment channel are provided to replenish the liquid in the conductive tank and the oxidation tank, respectively. Additionally, by providing the first discharge channel and the second discharge channel, liquid entering the first discharge tank can flow out through the first discharge channel in a timely manner, and liquid entering the second discharge tank can flow out through the second discharge channel in a timely manner.

[0013] Furthermore, the first water-pressing roller in the first water-pressing roller group near the oxidation tank has a gap n2 between it and the inner wall of the first discharge channel, and the second water-pressing roller in the second water-pressing roller group near the conductive channel has a gap m2 between it and the inner wall of the second discharge channel. This achieves secondary water pressing while preventing direct contact and friction between the first water-pressing roller and the first discharge channel, and also preventing direct contact and friction between the second water-pressing roller and the second discharge channel.

[0014] Furthermore, in the first pressure roller group, the central axis of the upper pressure roller is higher than the upper edge of the first channel, and the central axis of the lower pressure roller is lower than the lower edge of the first channel; in the second pressure roller group, the central axis of the upper pressure roller is higher than the upper edge of the second channel, and the central axis of the lower pressure roller is lower than the lower edge of the second channel. This design better achieves liquid blocking.

[0015] Furthermore, a first overflow port is provided on the side wall of the conductive tank at a position higher than the first channel, and a second overflow port is provided on the side wall of the oxidation tank at a position higher than the second channel. By providing the first overflow port, when the liquid in the conductive tank is higher than the set liquid level, the liquid will flow out from the first overflow port; similarly, by providing the second overflow port, when the liquid in the oxidation tank is higher than the set liquid level, the liquid will flow out from the second overflow port.

[0016] Furthermore, a fifth channel is provided on the side of the conductive groove opposite to the first channel, and a sixth channel is provided on the side of the oxidation groove opposite to the second channel. This facilitates the passage of the unwound roll.

[0017] Furthermore, the first, second, fifth, and sixth channels, as well as the first and second conveying channels, allow the unwound stock to pass horizontally. This prevents the unwound stock from being conveyed in a bent manner. Attached Figure Description

In this embodiment, multiple first overflow ports 14A are provided, and the first overflow ports 14A can be provided on the front side wall, the rear side wall, or both sides of the conductive tank.

[0024] An anode electrode 9A is disposed on the bottom and / or side wall of the conductive tank 1A and within the liquid. When the anode electrode 9A is energized, electricity can be conducted to the unwound coil 20 through the liquid.

[0025] like Figure 1 As shown, oxidation tank 2A ​​is used to hold liquid 100A containing electrolyte. Oxidation tank 2A ​​has a first cavity 20A. A second channel 21A is provided in the middle of the left side of conductive tank 2A, and a sixth channel 22A is provided in the middle of the right side of oxidation tank 2A. The second channel 21A and the sixth channel 22A are on the same horizontal plane, and the first channel and the second channel are also on the same horizontal plane. A second replenishment channel 23A is provided on oxidation tank 2A ​​to facilitate the replenishment of liquid into oxidation tank 2A, so as to ensure that the liquid level in oxidation tank 2A ​​is always maintained within a preset liquid level height range. In this embodiment, the second replenishment channel 23A is provided on the top or side wall of oxidation tank 2A.

In this embodiment, multiple second overflow ports 24A are provided, and the second overflow ports 24A can be provided on the front side wall, the rear side wall, or both sides of the oxidation tank.

[0026] A cathode electrode 91A is disposed at the bottom and / or top of the oxidation tank 2A ​​and within the liquid. When the cathode electrode 91A is energized, electricity can be conducted to the unwound coil 20 through the liquid.

[0027] The first drain tank 3A has a first drain cavity 30A. A third channel 31A is provided on the side of the first drain tank 3A near the oxidation tank 2A. A first drain channel 32A is provided at the bottom of the first drain tank 3A, so that the liquid flowing into the first drain tank 3A can be discharged in time through the first drain channel. The second drain tank 4A has a second drain cavity 40A. A fourth channel 41A is provided on the side of the second drain tank 4A near the conductive tank 1A. A second drain channel 42A is provided at the bottom of the second drain tank 4A, so that the liquid flowing into the second drain tank 4A can be discharged in time through the second drain channel.

[0028] The first water-pressing roller mechanism includes one or more first water-pressing roller groups 5A. In this embodiment, two groups of first water-pressing roller groups 5A are provided. One group of first water-pressing roller groups is located near the conductive groove 1A, and the other group of first water-pressing roller groups is located near the inner wall of the first drainage groove 3A on the side away from the conductive groove 1A. There is a gap n1 between the first water-pressing roller 51A in the first water-pressing roller group near the conductive groove 1A and the outer wall of the conductive groove. There is a gap n2 between the first water-pressing roller 51A in the first water-pressing roller group 5A on the side near the oxidation groove 2A and the inner wall of the first drainage groove 3A. There is a first gap 50A between the two groups of first water-pressing roller groups 5A. In this way, the liquid flowing from the conductive groove 1A into the first drainage groove 3A can flow down through the first gap and out through the first drainage channel. The first water-pressing roller group 5A includes two first water-pressing rollers 51A arranged vertically. There is a first conveying channel between the two first water-pressing rollers 51A for the unwound roll material 20 to pass through. The central axis of the first water-pressing roller located on the upper side of the first water-pressing roller group is higher than the upper edge of the first channel, and the central axis of the first water-pressing roller located on the lower side of the first water-pressing roller group is lower than the lower edge of the first channel. In this way, the gap between the first water-pressing roller 51A and the outer wall of the conductive groove 1A and the inner wall of the first drainage groove 3A is small, avoiding direct contact and friction between the first water-pressing roller 51A and the outer wall of the conductive groove 1A and the inner wall of the first drainage groove 3A, and the water-blocking effect is good.

[0029] The second water-pressing roller mechanism includes one or more sets of second water-pressing roller groups 6A. In this embodiment, two sets of second water-pressing roller groups 6A are provided. One set of second water-pressing roller groups is located near the oxidation tank 2A, and the other set of second water-pressing roller groups is located near the inner wall of the second drainage tank 4A on the side away from the oxidation tank 2A. There is a gap m1 between the second water-pressing roller 61A in the second water-pressing roller group near the oxidation tank 2A ​​and the outer wall of the oxidation tank. There is a gap m2 between the second water-pressing roller 61A in the second water-pressing roller group 6A on the side near the oxidation tank 2A ​​and the inner wall of the second drainage tank 4A. There is a second gap 60A between the two sets of second water-pressing roller groups 6A. In this way, the liquid flowing from the oxidation tank 2A ​​into the second drainage tank 4A can flow down through the second gap and out through the second drainage channel. The second water-pressing roller group 6A includes two second water-pressing rollers 61A arranged vertically. There is a second conveying channel between the two second water-pressing rollers 61A for the unwound roll 20 to pass through. The central axis of the upper second water-pressing roller in the second water-pressing roller group is higher than the upper edge of the second channel, and the central axis of the lower second water-pressing roller in the second water-pressing roller group is lower than the lower edge of the second channel. In this way, the gap between the second water-pressing roller 61A and the outer wall of the oxidation tank 2A ​​and the inner wall of the second drainage channel 4A is small, avoiding direct contact and friction between the second water-pressing roller 61A and the outer wall of the oxidation tank 2A ​​and the inner wall of the second drainage channel 4A, and the water-blocking effect is good.

[0030] In this embodiment, the first channel, the second channel, the fifth channel, the sixth channel, the first conveying channel, and the second conveying channel allow the unwound roll to pass horizontally.

[0031] In this embodiment, before use, a liquid such as electrolyte is injected into the conductive tank 1A and the oxidation tank 2A, ensuring the liquid level is higher than the first channel 11A and the second channel 21A. The unwound stock then sequentially passes through the fifth channel 12A, the conductive tank 1A, the first channel 11A, the first conveying channel, the third channel 31A, the fourth channel 41A, the second conveying channel, the second channel 21A, the oxidation tank 2A, and the sixth channel 22A. The unwound stock can be driven by other driving mechanisms, such as multiple sets of drive rollers located outside the conductive and oxidation tanks. Each set of drive rollers includes two drive rollers, and at least one drive roller in each set is connected to a drive motor. When the drive rollers rotate, they drive the unwound stock. In this embodiment, the first and second pressure rollers can be configured as either drive rollers or driven rollers. During this process, the anode electrode 9A imparts an anode charge to the unwound stock 20 through the liquid in the conductive tank, and the cathode electrode 91A provides a cathode charge through the oxidation tank, thereby oxidizing the surface of the unwound stock within the oxidation tank. In this embodiment, during the process of the unwound roll 20 entering the oxidation tank 2A ​​from the conductive tank 1A, since the liquid level is higher than both the first channel 11A and the second channel 21A, the liquid in the conductive tank 1A will flow out through the first channel 21A via gap n1, and the liquid in the oxidation tank 2A ​​will flow out through the second channel 21A via gap m1. However, in this embodiment, due to the presence of a first pressure roller group and a second pressure roller group, the first pressure roller group near the conductive tank 1A will partially block the liquid flowing out from the first channel, preventing the liquid from flowing out from the first channel 11A. The amount of liquid flowing out of tank A is reduced, and then the liquid is subjected to secondary pressure water isolation by another first pressure water roller group located away from the conductive tank 1A, so that the liquid flows out through the first gap 50A and then through the first discharge channel 32A. At the same time, the second pressure water roller group located near the oxidation tank 2A ​​partially blocks the liquid flowing out of the second channel 21A, reducing the amount of liquid flowing out of the second channel 21A. Then, the liquid is subjected to secondary pressure water isolation by another second pressure water roller group located away from the oxidation tank 2A, so that the liquid flows out through the second gap 60A and then through the second discharge channel 42A. Therefore, liquid cross-contamination between the conductive tank and the oxidation tank can be effectively avoided, and the anodic electricity cannot be partially conducted through the cross-contamination liquid. This allows the anodic electricity to be transferred from the unwound coil itself into the oxidation tank. Therefore, the unwound coil can be better oxidized in the oxidation tank, thereby improving the oxidation effect.

[0032] In this embodiment, the conductive groove 1A and the first drain groove 3A can be separated by the first side plate 13, and the first channel 11A is disposed on the first side plate 13; the oxidation groove 2A and the second drain groove 4A can be separated by the second side plate 24, and the second channel 21A is disposed on the second side plate 24.

[0033] Example 2.

[0034] like Figure 2 As shown, the difference between this embodiment 2 and embodiment 1 is only that: a first receiving tank 7A is also provided on the left side of the conductive tank 1A. The first receiving tank 7A is provided with a first receiving cavity 71A and a seventh channel 72A. A third drain channel 73A communicating with the first receiving cavity 71A is provided at the bottom of the first receiving tank 7A. The first receiving tank 7A can receive liquid such as electrolyte flowing out of the conductive tank 1A and can provide a buffer space for the electrolyte flowing out of the conductive tank 1A. The electrolyte flows into the first receiving tank 7A through the fifth channel, and the electrolyte in the first receiving tank 7A can flow out through the third drain channel 73A. A second receiving tank 8A is also provided on the right side of the oxidation tank 2A. The second receiving tank 8A is provided with a second receiving cavity 81A and an eighth channel 82A. A fourth discharge channel 83A communicating with the second receiving cavity 81A is provided at the bottom of the second receiving tank 8A. The second receiving tank 8A can receive liquid such as electrolyte flowing out of the oxidation tank 2A ​​and can provide a buffer space for the electrolyte flowing out of the oxidation tank 2A. The electrolyte flows into the second receiving tank 8A through the sixth channel and flows out of the second receiving tank 8A through the fourth discharge channel 83A.

A fourth water-pressing roller group 600A with the same structure as the second water-pressing roller group is provided in the second receiving groove 8A, and its function is the same as that of the second water-pressing roller group.
