Description

TECHNICAL FIELD

[0001] The utility model belongs to anodic aluminum roll production equipment technical field, concretely relates to a kind of anodic aluminum roll full-automatic production line conductive roller conductive oxidation tank. BACKGROUND

[0002] In order to make the surface characteristics of ordinary aluminum roll more superior, more suitable for the use requirements of various application scenarios, the current popular and general method is to form an aluminum oxide film layer on the surface of ordinary aluminum roll using anodic oxidation process, which makes ordinary aluminum roll have the characteristics of high strength, good bending resistance, good wear resistance, good corrosion resistance, superior high-temperature performance and high insulation, thereby providing more effective protection for motor vehicle license plate in various special application environments.

[0003] The existing conductive roller conductive oxidation tank, such as the Chinese utility model patent "Aluminum strip anodic oxidation production line conductive unit" with the authorization announcement number CN208414596U, includes a first conductive roller group, a first oxidation tank, a second conductive roller group, a second oxidation tank, a third conductive roller group, a third oxidation tank, a fourth conductive roller group and a fourth oxidation tank. The conductive roller group includes a tank body, a rectifier power supply and two aluminum conductive rollers installed in the tank body. A copper brush is arranged on the aluminum conductive roller. The aluminum conductive roller is connected to the positive electrode of the rectifier power supply through the copper brush. The edges of the first oxidation tank are uniformly provided with conductive plates, which are connected to the negative electrode of the rectifier power supply.

[0004] However, in actual production process, it is found that the first oxidation tank grows an oxide film of 1um, the second oxidation tank grows an oxide film of 3um, the third oxidation tank grows an oxide film of 5um, and the fourth oxidation tank no longer grows an oxide film, but instead eliminates the oxide film generated in front, causing the oxide film to fail to meet the predetermined product requirement of 5-8um. The reason is that the growing oxide film affects the conductivity. The aluminum roll with a certain thickness of oxide film is no longer conductive, and cannot continue to grow oxide film. In addition, the sulfuric acid soaking in the fourth oxidation tank electrolyte eliminates the oxide film, and the combination of four conductive rollers and four oxidation tanks consumes a large amount of electricity. To solve the above problems, it is necessary to develop a kind of anodic aluminum roll full-automatic production line conductive roller conductive oxidation tank. UTILITY MODEL CONTENTS

Specific embodiments

[0029] The technical scheme of the utility model will be further specifically explained in combination with the drawings.

[0030] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 And Figure 8As shown, this utility model provides a conductive roller conductive oxidation tank for a fully automatic production line of anodized aluminum coils, including an oxidation tank body 1, an electrolyte 9 located in the oxidation tank body, conductive rollers A3 and B5, conductive plates A12 and B11, anodizing power supply A15 and anodizing power supply B17. Conductive rollers A3 and B5 are sequentially arranged at the aluminum coil input end of the oxidation tank body 1, and conductive plates A12 and B11 are sequentially arranged on the same plane within the oxidation tank body 1. Conductive rollers A3 and A12 are respectively connected to the positive and negative terminals of the anodizing power supply A15, and conductive rollers B5 and B11 are respectively connected to the positive and negative terminals of the anodizing power supply B17. Conductive plates A12 and B11 can be arranged above or below the aluminum coil 8.

[0031] When the anodizing power supply A15 and the anodizing power supply B17 are working, that is, when they provide a suitable working power supply, the conductive roller A3 and the conductive plate A12, and the conductive roller B5 and the conductive plate B11 respectively perform anodizing process on the aluminum coil 8 that is continuously moving above or below them through the electrolyte 9.

[0032] Specifically, this utility model provides four implementation methods: (1) Conductive plate A and conductive plate B are either a single conductive plate or two array structures formed by arranging multiple conductive plates A and multiple conductive plates B at a certain distance; (2) Conductive plate A12 and conductive plate B11 are located above or below aluminum coil 8.

[0033] like Figure 1 In the first embodiment shown, conductive plate A12 and conductive plate B11 are both single conductive plates located below aluminum coil 8. In this case, one side of conductive plate A12 extends upwards at intervals, bypassing the side wall of the oxidation tank body 1, and connects to copper busbar A16. Similarly, one side of conductive plate B11 extends upwards at intervals, bypassing the side wall of the oxidation tank body 1, and connects to copper busbar B18. Copper busbars A16 and B18 are respectively connected to the negative terminals of anodizing power supplies A15 and B17. The interval-like upward extension is used to allow space for the installation of the idler roller 19.

[0034] like Figure 2In the second embodiment shown, conductive plates A12 and B11 are two array structures formed by arranging multiple conductive plates A12 and multiple conductive plates B11 at a certain distance, respectively, and both are located below the aluminum coil 8. In this case, the same side of each conductive plate A12 extends upwards, bypassing the sidewall of the oxidation tank body 1, and connects to a copper busbar A16. Similarly, the same side of each conductive plate B11 extends upwards, bypassing the sidewall of the oxidation tank body 1, and connects to a copper busbar B18. Copper busbars A16 and B18 are connected to the negative terminals of the anodizing power supplies A15 and B17, respectively. The spaced arrangement provides space for the idler roller 19.

[0035] like Figure 3 In the fourth embodiment shown, conductive plate A12 and conductive plate B11 are both single conductive plates located above aluminum coil 8. In this case, one side of conductive plate A12 extends upwards, either entirely or intermittently, around the side wall of the oxidation tank body 1 and connects to copper busbar A16. Similarly, one side of conductive plate B11 extends upwards, either entirely or intermittently, around the side wall of the oxidation tank body 1 and connects to copper busbar B18. Copper busbars A16 and B18 are respectively connected to the negative terminals of anodizing power supplies A15 and B17. The idler roller 19 is located below conductive plates A12 and B11, requiring no additional space for its installation.

[0036] like Figure 4 In the fourth embodiment shown, conductive plates A12 and B11 are two array structures formed by arranging multiple conductive plates A12 and multiple conductive plates B11 at a certain distance, respectively, and are located above the aluminum coil 8. In this case, the same side of each conductive plate A12 extends upwards, bypassing the sidewall of the oxidation tank body 1, and connects to copper busbar A16. Similarly, the same side of each conductive plate B11 extends upwards, bypassing the sidewall of the oxidation tank body 1, and connects to copper busbar B18. Copper busbars A16 and B18 are connected to the negative terminals of anodizing power supplies A15 and B17, respectively. Likewise, the idler roller 19 is located below the conductive plates A12 and B11, requiring no additional space for its installation.

[0037] In practice, the second implementation method is preferred because it has better overall production results. Therefore, the other settings of the second implementation method will be described in detail below.

[0038] Conductive plate A12 and conductive plate B11 are flat plates or W-shaped plates, with W-shaped plates being preferred to increase the conductive area, improve the conductivity, increase the oxide film growth rate, and save electricity.

[0039] Conductive rollers A3 and B5 are made of aluminum or copper, with copper being preferred due to their superior conductivity.

[0040] The one end of the conductive roller A3 and the conductive roller B5 is respectively sleeved with the copper sleeve A13 and the copper sleeve B14, and the conductive roller A3 and the conductive roller B5 are respectively connected to the positive pole of the anodic oxidation power supply A15 and the anodic oxidation power supply B17 through the copper sleeve A13 and the copper sleeve B14. The copper sleeve A13 and the copper sleeve B14 are respectively connected to the positive pole of the anodic oxidation power supply A15 and the anodic oxidation power supply B17, and then are respectively contacted with the rotating copper conductive roller A3 and the conductive roller B5 to complete the power transmission. Compared with the original copper brush contact, the copper sleeve contact has a large conductive area and high conductive efficiency.

[0041] The material of the conductive plate A12 and the conductive plate B11 is lead, titanium, titanium alloy, aluminum, aluminum alloy, tantalum, tantalum alloy, graphite or brass which is acid-resistant, corrosion-resistant and conductive, and preferably lead which has high cost performance.

[0042] The anodic oxidation power supply A15 and the anodic oxidation power supply B17 are direct current anodic oxidation power supply, alternating current anodic oxidation power supply or pulse current anodic oxidation power supply, and preferably rectifier which belongs to the direct current anodic oxidation power supply and is convenient to use.

[0043] Two guide rollers 7 are arranged at the two ends of the conductive plate A12 and the conductive plate B11 in the oxidation tank body 1, and are used to press down the aluminum roll 8 and immerse it in the electrolyte 9 to facilitate the smooth completion of the anodic oxidation work on the aluminum roll 8. The lower ends of the two guide rollers 7 are located above or below the conductive plate A12 and the conductive plate B11.

[0044] A plurality of carrier rollers 19 are arranged in the oxidation tank body 1 between the two guide rollers 7 to support the aluminum roll 8 and prevent it from sagging. The upper ends of the carrier roller array are substantially flush with the lower ends of the two guide rollers 7. The two guide rollers 19 press down the aluminum roll 8 from top to bottom and immerse it in the electrolyte 9, and the carrier roller array supports the aluminum roll 8 from bottom to top. The two guide rollers 19 and the carrier roller array cooperate with each other to keep the aluminum roll 8 in the same plane during continuous walking, thereby achieving good anodic oxidation effect.

[0045] In order to make the suspended conductive plate A12 and the conductive plate B11 work stably, the two conductive plates need to be supported. In the first case, when the lower ends of the two guide rollers 7 are located above the conductive plate A12 and the conductive plate B11, i.e. the aluminum roll 8 is located above the two conductive plates in the first and second embodiments, a plurality of vertical columns 20 are arranged at the lower ends of the conductive plate A12 and the conductive plate B11 on the bottom of the oxidation tank body 1 to support the conductive plate A12 and the conductive plate B11 and ensure their long-term stable work.

[0046] The second case is that the lower ends of the two guide rollers 7 are located below the conductive plate A12 and the conductive plate B11, that is, the aluminum roll 8 of the third and fourth embodiments is located below the two conductive plates, and the lower ends of the conductive plate A12 and the conductive plate B11 are provided with a plurality of brackets arranged between the two side walls of the oxidation tank body 1, and the stable long-term work of the conductive plate A12 and the conductive plate B11 is ensured by the support of the plurality of brackets. However, it should be noted that if the conductive plate A12 and the conductive plate B11 are an integral conductive plate, since the two conductive plates need to be connected to the anodic oxidation power supply, the conductive plate A and the conductive plate B can only be extended upward in a spaced manner and connected to the copper bar A16 and the copper bar B18, respectively, so as to leave space for the plurality of brackets. If the conductive plate A12 and the conductive plate B11 are two array structures arranged in sequence at a certain distance by a plurality of conductive plates A12 and a plurality of conductive plates B11, there is no need to consider the mutual staggered arrangement.

[0047] In specific implementation, the oxidation tank body 1, the guide roller 7, the supporting roller 19, the bracket, and the column 20 are insulators.

[0048] After the above installation is completed, the utility model can be put into use. First, the two rectifiers (that is, the anodic oxidation power supply A15 and the anodic oxidation power supply B17) are turned on, the conductive roller A3 and the conductive roller B5 are powered on, the aluminum roll 8 in contact with the two is powered on, the aluminum roll 8 itself becomes a positive electrode, the conductive plate A12 and the conductive plate B11 are powered on to become a negative electrode, then the aluminum roll 8 to be anodized is introduced into the oxidation tank body 1 through the guide-in roller 6, is pressed down by the two guide rollers 7 located at both ends of the oxidation tank body 1 and is submerged in the electrolyte 9, the positive electrode and the negative electrode form an electric circuit through the electrolyte 9, the aluminum roll 8 is continuously anodized, the treated aluminum roll 8 is guided out of the oxidation tank body 1 through the guide-out roller 10; during the period, the tensioning roller A2 and the tensioning roller B4 cooperate with the conductive roller A3 and the conductive roller B5 to complete the continuous conveying work of the aluminum roll 8 and increase the contact and conduction area between the aluminum roll 8 and the conductive roller A3 and the conductive roller B5, respectively; during the period, the electrolyte 7 flows through the externally configured cooling unit for circulating cooling.

[0049] The above only describes the preferred embodiments of the utility model and is not used to limit the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
