Description

Technical Field

[0001] The utility model belongs to the field of aluminum strip foil continuous oxidation, in particular to a conductive roller of aluminum strip foil continuous oxidation equipment. Background Art

[0002] The continuous oxidation of aluminum foil uses the principle of electrochemistry. With aluminum foil as the anode, an oxide film with certain electrical insulation is formed on its surface in a specific electrolyte with the help of corresponding processes. The aluminum foil with the electrical insulation oxide film is used to wrap the electromagnetic coils in various electronic devices, so that the coils have the characteristics of interlayer breakdown resistance, high temperature resistance, and good thermal conductivity. The commonly used continuous oxidation equipment for aluminum foil adopts the conductive wheel contact conductive method. The aluminum foil is pressed and contacted with the conductive wheels at both ends. A mercury cup is provided above the conductive wheel to achieve conduction between the aluminum foil and the rectifier anode.

[0003] However, as daily production progresses, equipment aging can easily lead to mercury leakage from the mercury cup, reducing the conductive effect and causing abnormal product quality. In severe cases, it may cause mercury poisoning to production personnel, causing irreversible damage. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a conductive roller for aluminum foil continuous oxidation equipment, which can enable the product to achieve continuous oxidation and avoid quality abnormalities such as electrical breakdown and electrical ablation. At the same time, non-mercury conductive rollers are used to completely eliminate the hidden dangers of mercury leakage and ensure safe production.

[0005] A conductive roller of an aluminum foil continuous oxidation device comprises a conductive cavity, wherein two ends of the conductive cavity are connected by a connector, and the connector and the conductive cavity are sealed by a sealing ring; a conductive central shaft penetrating the connector is provided in the conductive cavity, and a conductive bearing is provided on the conductive central shaft inside the conductive cavity; the conductive central shaft and the connector are connected by a transmission bearing, and the conductive central shaft is connected to the continuous oxidation device.

[0006] The conductive central axis, the conductive cavity and the conductive bearing are all made of copper.

[0007] The sealing ring is an acid and alkali resistant Teflon soft rubber ring.

[0008] The beneficial effects of the utility model are as follows:

[0009] 1. This application realizes the connection between the conductive central axis and the conductive cavity through a conductive bearing, thereby making the product charged, without the need for a mercury cup connection, thus eliminating mercury leakage;

[0010] 2. The conductive cavity and the connector of the present application are sealed by an acid- and alkali-resistant Teflon soft rubber ring as a sealing ring, which can prevent electrolytes such as sulfuric acid from entering the conductive cavity and corroding the conductive bearings, thereby extending the service life of the parts.

[0013] The present implementation is described in detail below with reference to the accompanying drawings.

[0014] like Figure 1 As shown, a conductive roller of an aluminum foil continuous oxidation device includes a conductive central axis 3, a conductive cavity 1, a conductive bearing 2, and a transmission bearing. The two ends of the conductive cavity 1 are connected by a connector 5, and the connector 5 and the conductive cavity 1 are sealed by a sealing ring 4; a conductive central axis 3 penetrating the connector 5 is provided in the conductive cavity 1, and a conductive bearing 2 is provided on the conductive central axis 3 inside the conductive cavity 1 to realize current transmission and rotation of the conductive cavity 1; the conductive central axis 3 and the connector 5 are connected by a transmission bearing, the conductive central axis 3 is connected to the continuous oxidation device, and the conductive cavity 1 can be rotated through the transmission bearing.

[0015] The transmission bearing includes a bearing seat 6, a bearing 7 and a bearing retaining ring 8. The bearing retaining ring 8, the bearing 7 and the bearing seat 6 are sequentially sleeved. The bearing retaining ring 8 is fixed to the bearing 7 by a bayonet 9. The bearing seat 6 is located on the inner side of the connecting piece 5.

[0016] The conductive central axis 3, the conductive cavity 4 and the conductive bearing 2 are all made of copper. The conductive bearing 2 is of type 6004 with a size of φ42*φ20*12 mm, which can increase the conductivity of the parts.

[0017] The sealing ring 4 is an acid- and alkali-resistant Teflon soft rubber ring with a size of φ20*φ25*φ3mm. The sealing ring 4 is tightened and compacted with the thread at the connection position to prevent electrolyte such as sulfuric acid from entering the conductive cavity 1 and corroding the conductive bearing, thereby extending the service life of the parts.

[0018] The anode of the continuous oxidation equipment of the utility model is connected to the conductive central shaft 3, the rectifier of the continuous oxidation equipment provides current, the conductive central shaft 3 transmits the current to the conductive cavity 1 through the conductive bearing 2, realizes the conductivity of the cavity, and then transmits the current to the aluminum foil. The conductive cavity 1 rotates freely under the tension of the aluminum foil and maintains high-speed production, so that the entire roll of aluminum foil is completely formed with an oxide film; the present application avoids the use of traditional mercury rotating conductive devices and replaces them with detachable bearings, which is a bearing conductive method.
