Description

Technical Field

[0001] This utility model relates to the field of conductive oxidation technology, specifically to an isolation conveying device between a conductive tank and an oxidation tank for anodizing coiled materials. Background Technology

[0002] Anodizing is a surface treatment technology based on electrochemical reactions. It is mainly used to improve the corrosion resistance, decorative properties, and other functional characteristics of metallic materials. By applying an external current, an oxide film is formed on the anode (metal), thereby improving the surface properties of the metal. Anodizing usually includes sulfuric acid anodizing.

[0003] For example, Chinese patent document No. 202310793861.9, published on September 1, 2023, discloses a conductive device for anodizing, including a storage box. Synchronous push rods are fixedly connected to both the left and right ends of the storage box. A plug is fixedly connected to the upper end of the synchronous push rod. A fixing plate is inserted into the plug and connected to the plug hole. A limit post is slidably connected inside the fixing plate. A connecting plate is fixedly connected to the upper end of the limit post. An electric push rod is provided inside the upper end of the fixing plate. The electric push rod is fixedly connected to the connecting plate through an output shaft. A mounting plate is fixedly connected to the lower end of the limit post.

[0004] The aforementioned literature describes anodizing aluminum alloy plates by having personnel pull a connecting plate downwards using an electric push rod. This causes the connecting plate to slide against a limiting post, which in turn pushes the mounting plate inside the fixed plate to move the connecting rod. The connecting rod then moves the fixed guide rail downwards towards the storage tank, allowing the aluminum alloy plate to slide better into the electrolyte to accommodate different heights. However, this method is only suitable for anodizing and conducting electricity on a single, independent aluminum alloy plate and is not applicable to anodizing aluminum coils during horizontal transport. Utility Model Content

[0005] The purpose of this invention is to provide an isolation conveying device between the conductive tank and the oxidation tank for anodizing coiled materials. The device completely separates the conductive tank and the oxidation tank with a simple structure, so that anodizing can be carried out efficiently.

[0006] This utility model provides the following technical solution: an isolation conveying device between a conductive tank and an oxidation tank for anodizing coiled material, comprising a conductive tank, an oxidation tank, and one or more conveying mechanisms. The conveying mechanisms are disposed between the conductive tank and the oxidation tank, which are arranged opposite to each other. One or more conveying mechanisms are disposed at one end of the conductive tank near the conveying mechanism one, and one or more conveying mechanisms are disposed at one end of the oxidation tank near the conveying mechanism one. The conveying mechanisms are disposed below the electrolyte level in the conductive tank, and the conveying mechanisms are disposed below the electrolyte level in the oxidation tank. The conveying mechanisms are disposed above the electrolyte levels in both the conductive tank and the oxidation tank. The coiled material located in the conductive tank passes through the bottom of the conveying mechanism two and then passes around the top of the conveying mechanism one to enter the bottom of the conveying mechanism three in the oxidation tank. The coiled material located on the conveying mechanism two in the conductive tank is located below the electrolyte level in the conductive tank, and the coiled material located on the conveying mechanism three in the oxidation tank is located below the electrolyte level in the oxidation tank.

[0007] The above setup involves immersing the coiled aluminum in a conductive tank and an oxidation tank via conveyor mechanisms two and three. Both the conductive and oxidation tanks are equipped with electrode plates. Applying a certain voltage causes the aluminum coil to become positively charged in the oxidation tank, thus enabling anodizing. Conveyor mechanism one is positioned higher than conveyor mechanisms two and three and located between the conductive and oxidation tanks, effectively separating them. This height difference allows the coiled aluminum to flow obliquely upwards around conveyor mechanism one before entering the oxidation tank obliquely downwards, achieving complete separation between the conductive and oxidation tanks. This ensures that the electrolytes in the conductive and oxidation tanks do not interfere with each other, resulting in higher oxidation efficiency. Furthermore, the conductive groove has an opening one on one side near the conveying mechanism one, an opening two on the other side of the conductive groove, and a conveying mechanism four outside the opening two.

[0008] The above configuration allows the metal anode coil to bypass the conveying mechanism four and enter the conductive groove through opening two, and then be conveyed out of the conductive groove obliquely upward through opening one.

[0009] Furthermore, the oxidation tank has an opening three on one side near the conveying mechanism one, an opening four on the other side of the oxidation tank, and a conveying mechanism five outside the opening four.

[0010] The above configuration allows the metal anode coil, which bypasses the first conveying mechanism, to enter the oxidation tank obliquely downwards through opening three, and then be conveyed out of the oxidation tank through opening four to enter the next process.

[0011] Furthermore, the height of the electrolyte level in the conductive tank is less than the height from opening one to the bottom of the conductive tank, and the height of the electrolyte level in the oxidation tank is less than the height from opening three to the bottom of the oxidation tank.

[0012] The above settings prevent electrolyte from overflowing from opening one in the conductive tank or opening two in the oxidation tank.

[0013] Furthermore, the conductive tank is provided with electrolyte overflow ports on both sides adjacent to the second opening, and the oxidation tank is provided with electrolyte overflow ports on both sides adjacent to the fourth opening. Both the conductive tank and the oxidation tank are provided with electrolyte spray pipes at the bottom, and the spray pipes are provided with electrolyte inlets and connected to an external power pump.

[0014] The above setup uses a power pump to draw electrolyte into the conductive tank and oxidation tank through a nozzle. The electrolyte level in the conductive tank and oxidation tank can be controlled by the inflow and outflow rates of the electrolyte inlet and outlet.

[0015] Furthermore, the second conveying mechanism includes a second rotating shaft and a second roller, with the second roller sleeved on the second rotating shaft, and both ends of the second rotating shaft connected to the inner wall of the conductive groove.

[0016] The above configuration facilitates the winding material entering the conductive tank to bypass the bottom of roller two, so that the metal anode coil is completely immersed in the electrolyte of the conductive tank.

[0017] Furthermore, the conveying mechanism three includes a rotating shaft three and a roller three, with the roller three sleeved on the rotating shaft three, and both ends of the rotating shaft three connected to the inner wall of the oxidation tank.

[0018] The above configuration allows the metal anode coil to bypass the bottom of roller three when entering the oxidation tank, ensuring that the coil is completely immersed in the electrolyte of the oxidation tank.

[0019] Furthermore, the height from the bottom of roller two to the bottom of the conductive tank is less than the height of the electrolyte level in the conductive tank, and the height from the bottom of roller three to the bottom of the oxidation tank is less than the height of the electrolyte level in the oxidation tank.

[0020] The above settings ensure that the roll material entering the conductive tank and passing the bottom of roller two is completely immersed in the electrolyte of the conductive tank, and at the same time, the roll material entering the oxidation tank and passing the bottom of roller three is completely immersed in the electrolyte of the oxidation tank.

[0021] Furthermore, the conveying mechanism includes a roller, a rotating shaft, a drive motor, and two support frames. The support frames are positioned between the conductive tank and the oxidation tank. Both ends of the rotating shaft are connected to the support frames via bearings. The output end of the drive motor, located on one side of the support frame, is connected to one end of the rotating shaft. The roller is fitted onto the rotating shaft.

[0022] The above settings facilitate the rotation of the shaft and roller by the drive motor, thereby enabling the coiled material to be continuously fed into the oxidation tank for anodizing.

[0023] Furthermore, the conductive tank is provided with two or more anode plates, and the oxidation tank is provided with two or more cathode plates.

[0024] With the above settings, after applying a certain voltage to the anode plate and cathode plate, the coiled material can be anodized in the oxidation tank. Attached Figure Description

[0026] Figure 2 This is a schematic diagram of the conveying mechanism one in this utility model. Detailed Implementation

[0027] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1-2 As shown, this utility model provides an isolation conveying device between a conductive tank and an oxidation tank for anodizing coiled material, including a conductive tank 1, an oxidation tank 2, and one or more conveying mechanisms 3. The conveying mechanism 3 is disposed between the conductive tank 1 and the oxidation tank 2, which are arranged opposite to each other. The conveying mechanism 3 includes a roller 31, a rotating shaft 32, a drive motor 33, and two support frames 34. The support frames 34 are disposed between the conductive tank 1 and the oxidation tank 2. The two ends of the rotating shaft 32 are connected to the support frames 34 through bearings. The output end of the drive motor 33, which is disposed on one side of the support frame 34, is connected to one end of the rotating shaft 32. The roller 31 is sleeved on the rotating shaft 32, which facilitates the rotation of the rotating shaft 32 and the roller 31 by the drive motor 33. Thus, the coiled material 9, after being conductive in the conductive tank 1, is continuously conveyed to the oxidation tank 2 for oxidation reaction under the drive of the roller 31.

[0029] like Figure 1 As shown, one or more conveying mechanisms are provided at one end of the conductive tank 1 near the conveying mechanism 3, and one or more conveying mechanisms are provided at one end of the oxidation tank 2 near the conveying mechanism 3. In this embodiment, both conveying mechanism 2 and conveying mechanism 3 are provided in pairs. The conveying mechanism 2 is set below the electrolyte level 8 in the conductive tank, and the conveying mechanism 3 is set below the electrolyte level 8 in the oxidation tank. The conveying mechanism 2 in the conductive tank and the conveying mechanism 3 in the oxidation tank are set at the same height. The roller 31 is set above the electrolyte level 8 in both the conductive tank and the oxidation tank.

[0030] like Figure 1 As shown, the second conveying mechanism includes a second rotating shaft 41 and a second roller 42. The second roller 42 is sleeved on the second rotating shaft 41, and the height from the top of the second roller 42 to the bottom of the conductive tank 1 is less than the height of the electrolyte surface 8 in the conductive tank. The two ends of the second rotating shaft 41 are connected to the inner wall of the conductive tank 1, so that the metal anode coil 9 entering the conductive tank can bypass the bottom of the second roller 42, so that the metal anode coil 9 is completely immersed in the electrolyte in the conductive tank 1.

[0031] In this embodiment, the conductive tank 1 has an opening 11 on the side near the conveying mechanism 3, and the height of the electrolyte level 8 in the conductive tank is less than the height from the opening 11 to the bottom of the conductive tank. The other side of the conductive tank has an opening 2 12, and a conveying mechanism 4 is provided outside the opening 2 12, so that the metal anode coil 9 passes around the conveying mechanism 4 and enters the conductive tank 1 through the opening 2 12, and is conveyed out of the conductive tank 2 obliquely upward through the opening 11.

[0032] like Figure 1 As shown, the conveying mechanism includes a rotating shaft 51 and a roller 52. The roller 52 is sleeved on the rotating shaft 51, and the height from the top of the roller 52 to the bottom of the oxidation tank 2 is less than the height of the electrolyte surface 8 in the oxidation tank. The two ends of the rotating shaft 51 are connected to the inner wall of the oxidation tank 2, so that the rolled material 9 entering the oxidation tank can bypass the bottom of the roller 52, so that the rolled material 9 is completely immersed in the electrolyte of the oxidation tank 2.

[0033] In this embodiment, the oxidation tank 2 is provided with an opening 3 21 on the side near the conveying mechanism 3, and the height of the electrolyte level 8 in the oxidation tank is less than the height from the opening 3 21 to the bottom of the oxidation tank. The other side of the oxidation tank 2 is provided with an opening 4 22, and a conveying mechanism 5 is provided outside the opening 4 22, which allows the coil 9 that bypasses the conveying mechanism 3 to enter the oxidation tank 2 obliquely downward from the opening 3 21, and be conveyed out of the oxidation tank 1 through the opening 4 22 to enter the next process.

[0034] The structural configurations of conveying mechanism 4 and conveying mechanism 5 are the same as those of conveying mechanism 3, and will not be described again here. In this embodiment, the difference between conveying mechanism 4, conveying mechanism 5 and conveying mechanism 3 lies in the different height settings of support frame 1.

[0035] In this embodiment, the conductive tank 1 is equipped with two or more anode plates 13, which are located below the second conveying mechanism and are immersed in the electrolyte. The oxidation tank 2 is equipped with two or more cathode plates 23, which are located above and below the third conveying mechanism and are also immersed in the electrolyte. When a certain voltage is applied to the anode plates 13 and cathode plates 23, a circuit is formed, allowing the coiled material to undergo anodizing in the oxidation tank. The electrolytes in the conductive tank and the oxidation tank can be sulfuric acid solutions of different concentrations. By setting this structure, the coiled material 9 can undergo conductive and oxidation reactions in the conductive tank 1 and the oxidation tank 2 respectively, without affecting each other, and the conductive process achieved through the electrolyte is effective.

[0036] In this embodiment, electrolyte overflow ports (not shown in the figure) are provided on both sides adjacent to the conductive tank 1 and the second opening 12, and electrolyte overflow ports are provided on both sides adjacent to the fourth opening 22 of the oxidation tank 2. Electrolyte spray pipes (not shown in the figure) are provided at the bottom of both the conductive tank 1 and the oxidation tank 2. Electrolyte inlets (not shown in the figure) are provided on the spray pipes. The spray pipes are connected to an external power pump. Electrolyte is drawn into the conductive tank 1 and the oxidation tank 2 through the power pump. The height of the electrolyte level 8 in the conductive tank and the oxidation tank can be controlled by the inflow and outflow of the electrolyte inlet and the electrolyte overflow port, thereby ensuring that the roll material 9 is completely immersed in the electrolyte and preventing the electrolyte from overflowing from the first opening 11 of the conductive tank or the third opening 21 of the oxidation tank.

[0037] The working principle of this utility model is as follows: Driven by conveying mechanism 1 (3), conveying mechanism 4 (4), and conveying mechanism 5 (4), the outer roll material 9 passes around conveying mechanism 4 and enters the conductive tank through opening 2 of the conductive tank. Then it passes around the bottom of conveying mechanism 2 to ensure that the roll material is immersed in the conductive tank to achieve conductivity. Next, it passes obliquely upward from opening 1, passes around the top of conveying mechanism 1, and then obliquely downward into the oxidation tank. It is immersed in the oxidizing electrolyte around the bottom of conveying mechanism 3 to achieve anodizing. Finally, it is conveyed out of the oxidation tank through opening 4 and passes around conveying mechanism 5 to enter the next process.
