Technical Field

[0001] This utility model belongs to the field of electrode foil production technology, specifically relating to a device for preventing arcing on the foil surface during electrode foil production. Background Technology

[0002] The production process of electrode foil mainly includes etching and formation processes. Both processes require applying electricity to the foil surface. The main method of applying electricity is to use a rectified power supply in conjunction with conductive rollers and electrode plates to apply electricity to the electrode surface.

[0003] In the production of electrode foil for aluminum electrolytic capacitors, during the electrochemical corrosion process, the current applied to the foil surface is about 2000A. When the foil surface tension fluctuates, the contact resistance between the aluminum foil and the electrolytic roller changes, which can easily lead to phenomena such as foil surface arcing and foil surface breakdown, resulting in a great deal of production waste. Utility Model Content

The end of the roller shaft is rotatably connected to a connecting seat, and the roller cylinder is fixedly sleeved on the outer side of the roller shaft.

The fixed shell is fixedly connected to the connecting seat, and the movable shell is slidably connected inside the fixed shell. The other end of the movable shell extends through to the outside of the fixed shell and is fixedly connected to the connecting seat.

[0012] Preferably, a sliding groove is provided on the inner wall of the fixed shell, and a slider is slidably connected in the sliding groove, the slider being fixedly connected to the outer wall of the fixed shell.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see Figure 1-3 This embodiment provides the following technical solution: a device for preventing arcing on the foil surface during electrode foil production, comprising a frame 1 and a foil sheet 2, wherein a conductive roller 3 is rotatably connected to the frame 1, and the current on the conductive roller 3 can be conducted to the foil sheet 2 through the conductive roller 3.

[0030] An upstream drive roller 4 is rotatably connected to the left side of the conductive roller 3 on the frame 1, and a downstream drive roller 5 is rotatably connected to the right side of the conductive roller 3 on the frame 1. The foil 2 moves smoothly by passing through the upstream drive roller 4, the conductive roller 3 and the downstream drive roller 5 in sequence. In some embodiments, the upstream drive roller 4 and the downstream drive roller 5 can be used to traction the foil 2.

[0031] A pressure seat 6 is fixedly connected to the frame 1, and a pressure roller 7 is rotatably connected to the pressure seat 6. The pressure roller 7 is positioned above the conductive roller 3, and the pressure roller 7 and the conductive roller 3 work together to form the pressing structure of the foil 2.

[0032] Both ends of the pressure roller 7 are rotatably connected to the connecting seats 10, which are fixedly connected to the pressure seat 6. The pressure roller 7 includes a roller shaft 701 and a roller 702. The end of the roller shaft 701 is rotatably connected to the connecting seat 10. The roller 702 is fixedly sleeved on the outer side of the roller shaft 701. Bearings 703 are also fixedly connected to the roller shaft 701 on the front and rear sides of the roller 702. In some embodiments, the bearings 703 are ceramic bearings 703, which can fix the roller 702 on the roller shaft 701.

[0033] In some embodiments, the pressure roller 7 rotates synchronously with the conductive roller 3. Relying on its own weight, the pressure roller 7 presses the foil 2 and the conductive roller 3 together, ensuring that the contact resistance between the two remains constant, thereby avoiding arcing.

[0034] In some embodiments, the pressure roller 7 can press the foil 2 and make it contact the surface of the conductive roller 3 by its own weight. The structure is simple, the failure rate is low, and it can also effectively reduce the frequency of foil surface arcing, stabilize the production process, reduce waste, and avoid frequent grinding of the surface of the conductive roller 3, thus extending the service life of the conductive roller 3.

[0035] An anode plate 8 and a cathode plate 9 are fixedly connected to the frame 1. The anode plate 8 and the cathode plate 9 are spaced apart to form a channel through which the foil 2 passes. As the aluminum foil passes through the anode plate 8 and the cathode plate 9, it forms an oxide film through an electrochemical reaction. After special treatment, its electrical performance is improved, and it is finally used to manufacture aluminum electrolytic capacitors.

[0036] Example 2

[0037] Please see Figure 4-8 In order to adjust the distance between the pressure roller 7 and the conductive roller 3 according to the thickness of the foil 2, an adjustment mechanism 11 is also included to adjust the horizontal height of the pressure roller 7. The adjustment mechanism 11 includes a fixed shell 1101 and a movable shell 1102. The fixed shell 1101 is fixedly connected to the connecting seat 10, and the movable shell 1102 is slidably connected inside the fixed shell 1101. The other end of the movable shell 1102 extends through to the outside of the fixed shell 1101 and is fixedly connected to the connecting seat 10. By setting the fixed shell 1101 and the movable shell 1102, the horizontal height of the connecting seat 10 and the pressure roller 7 can be adjusted by adjusting the horizontal height of the movable shell 1102 inside the fixed shell 1101.

[0038] A groove 1103 is provided on the inner wall of the fixed shell 1101. A slider 1104 is slidably connected in the groove 1103. The slider 1104 is fixedly connected to the outer wall of the fixed shell 1101. Through the groove 1103 and the slider 1104, the movable block can be vertically limited, which increases the stability of the movable block moving in the fixed block.

[0039] In some embodiments, a bolt 1105 is threaded through the bottom of the fixed housing 1101. One end of the bolt 1105 extends into the interior of the fixed housing 1101 and is rotatably connected to the movable housing 1102. The bolt 1105 can be rotated in the forward or reverse direction to screw the bolt 1105 into or out of the fixed housing 1101. During the process of screwing the bolt 1105 into or out, the bolt 1105 drives the movable block to move vertically within the fixed housing 1101, thereby adjusting the distance between the pressure roller 7 and the conductive roller 3.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
