Description
Technical Field
[0001] This application relates to the field of copper foil manufacturing technology, and more specifically, to a conductive device for a foil production machine. Background Technology
[0002] Electrolytic copper foil is a key material in the manufacture of lithium-ion batteries, printed circuit boards (PCBs), and copper-clad laminates. Domestic and international manufacturers generally use foil-making machines to produce electrolytic copper foil. The conductive device of the foil-making machine mainly refers to the connection between the rectifier and the cathode roller. During operation, the cathode roller is a continuously rotating component, with an electrolytic current typically exceeding 20,000A, sometimes reaching around 50,000A. Under these high current conditions, the conductive device of the foil-making machine is crucial to the quality and stability of the electrolytic copper foil. During operation, the conductive ring and the cathode shoe in the conductive device constantly rub against each other, leading to copper shavings that easily adhere to their surface. These shavings can cause localized point contact between the cathode shoe and the conductive ring, generating high heat and potentially burning the surface of the conductive ring or cathode shoe. This can result in pitting and uneven surface development, causing unstable rotation of the cathode roller, resulting in vibrations and affecting the stable operation of the equipment, ultimately impacting the quality of the copper foil.
[0003] There is very little research or reporting on conductive devices for foil-making machines, both domestically and internationally, that addresses the issue of copper shavings adhesion. Therefore, there is an urgent need for a conductive device for foil-making machines that, without compromising the device's conductivity or quality, solves at least one of the following problems: copper shavings easily adhere to the conductive rings and shoe surfaces of existing conductive devices; surface pits on the conductive rings; and unstable rotation of the cathode rollers.

[0016] Furthermore, the upper surface of the boot pole is also provided with a plurality of positioning holes that penetrate vertically through the boot pole, located on the other side of the first groove;

[0036] The present application will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present application, but do not limit the present application in any way. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present application. These all fall within the protection scope of the present application.
[0037] Reference Figure 1 As shown, a conductive device for a foil-making machine according to an embodiment of this application includes: a housing 1 with an internal cavity; a T-shaped electrode 2 disposed inside the cavity and abutting against the bottom and side walls of the cavity; a shoe electrode 3 mounted on the top of the T-shaped electrode 2; a friction inclined surface 31 inclined towards the bottom on one side of the upper surface of the shoe electrode 3; a first oil guide groove 32 on the inclined surface 31; and a conductive ring 4 abutting against the inclined surface 31 and in frictional contact with the inclined surface 31 of the shoe electrode 3.
[0038] Among them, there are multiple shoe poles 3, which are symmetrically arranged on both sides of the conductive ring 4. The upper surface of the shoe pole 3 is provided with a first groove 33, and the bottom of the first groove 33 is provided with a through hole 34 that penetrates the shoe pole 3. The side of the shoe pole 3 and the T-shaped electrode seat 2 is provided with a second oil guide groove 35 that is recessed into the shoe pole 3 and communicates with the through hole 34.
[0039] This application uses a T-shaped electrode base 2 set in the receiving cavity to ensure the stability of the conductive device structure and the ease of installation. At the same time, the friction-bearing inclined surface 31 on the shoe electrode 3 increases the contact area with the conductive ring 4, improves the conductivity, and effectively solves the problems of local high heat generation and sparks caused by copper shavings adhering to the conductive ring 4 and the shoe electrode 3 when they come into contact. Through the connection between the first oil guide groove 32 and the second oil guide groove 35 and the through hole 34, it is possible to collect the sliding conductive oil and copper shavings when they slide off the conductive ring 4 with the conductive oil, avoid the formation of impurities and turbulence that cause pollution, and improve the service life of the conductive device.
[0040] The second oil guide groove 35 is provided on the bottom wall of the shoe pole 3, extending from the bottom wall near the conductive ring 4 to the direction away from the conductive ring 4 until it connects with the through hole 34.
[0041] In some specific embodiments, it further includes: an oil outlet tank 5, which is disposed above the conductive ring 4, and a first conduit 7 is provided between the oil outlet tank 5 and the conductive ring 4 for dripping conductive oil from the oil outlet tank 5 onto the conductive ring 4; one end of the first conduit 7 is connected to the oil tank, and the other end is located above the conductive ring 4.
[0042] During operation, the conductive oil inside the oil tank 5 is first dripped quickly onto the surface of the conductive ring 4 through the first conduit 7. The conductive ring 4 comes into frictional contact with the surface of the inclined surface 31 of the shoe electrode 3, causing the generated copper shavings to flow with the conductive oil. Under the action of the viscous flow of the conductive oil and the gravity of the copper shavings themselves, they fall into the first oil guide groove 32 and the first groove on the inclined surface 31. Through the first oil guide groove 32, the first groove 33 and the through hole 34, they flow through the second oil guide groove 35, thus realizing the function of removing copper shavings from the contact surface between the conductive ring 4 and the shoe electrode 3.
[0043] like Figure 2 As shown, in some specific embodiments, one end of the inclined surface 31 protrudes from the upper surface of the shoe electrode 3, and the first oil guide groove 32 has multiple grooves that extend from one end of the inclined surface 31 to the other end. The inclined surface 31 is provided with a conductive wear-resistant component 9, and the first oil guide groove 32 passes through the conductive wear-resistant component 9. The inner side of the conductive ring 4 is connected to the cathode roller shaft, and the shoe electrode 3 rubs against the conductive ring 4 through the conductive wear-resistant component 9 to transmit current.
[0044] By protruding one end of the inclined surface 31 onto the upper surface of the shoe electrode 3, and by setting multiple first oil guide grooves 32 extending along the inclined surface 31, it is convenient for conductive oil and copper shavings to flow along the inclined surface 31. At the same time, a conductive wear-resistant component 9 is set on the inclined surface 31, and the conductive ring 4 rubs against the shoe electrode 3 through the conductive wear-resistant component 9. The inner side of the conductive ring 4 is connected to the cathode roller shaft, and the shoe electrode 3 rubs against the conductive ring 4 through the conductive wear-resistant component 9 to realize the transmission of current.
[0045] The first oil guide groove 32 has a certain depth on the inclined surface 31 to avoid residual conductive oil and copper shavings in the part that directly contacts the conductive ring 4, thereby improving the conductivity stability.
[0046] In one specific embodiment, there are two shoe poles 3, which are symmetrically arranged on both sides of the conductive ring 4; at the same time, there are three first oil guide grooves 32, of which one shoe pole 3 has two first oil guide grooves 32 and the other shoe pole 3 has one first oil guide groove 32.
[0047] Specifically, one side of the first groove 33 is provided near the end of the inclined surface 31 and communicates with the first oil guide groove 32; multiple through holes 34 are provided at intervals at the bottom of the first groove 33.
[0048] In this application, there are three through holes 34, which are spaced apart along the bottom of the first groove 33 in the length direction. The number of second oil guide grooves 35 is the same as that of through holes 34, and they are connected to each other. When conductive oil and copper shavings fall into the first groove 33 after friction, they are collected through the through holes 34 and the second oil guide grooves 35, which improves the response to the problem of local high heat and sparks caused by copper shavings generated when the conductive ring 4 contacts the shoe electrode 3.
[0049] like Figure 3 As shown, in some specific embodiments, the upper surface of the boot pole 3 is also provided with a number of positioning holes 36 that penetrate the boot pole 3 vertically, located on the other side of the first groove 33; at least one through hole 34 is located between two adjacent positioning holes 36.
[0050] By providing a positioning hole 36 on the upper surface of the shoe pole 3, the shoe pole 3 can be positioned and installed on the T-shaped pole seat 2. The first groove 33 is set on the side of the positioning hole 36 near the inclined surface 31 to facilitate installation and disassembly. At least one through hole 34 is located between two adjacent positioning holes 36 to prevent conductive oil and copper shavings from being stored in the first groove 33.
[0051] Specifically, the conductive and wear-resistant component 9 can be any one of copper alloy components, copper-based composite material components, or carbon brush material components.
[0052] In this embodiment, the conductive and wear-resistant component 9 is a copper-tungsten sheet.
[0053] like Figure 2 As shown, in some specific embodiments, the top upper surface of the T-shaped pole seat 2 is provided with a second groove 21 that is recessed inward, and the second groove 21 is connected to the second oil guide groove 35; the second groove 21 is located between the symmetrically arranged shoe poles 3.
[0054] By setting a second groove 21 between the top of the T-shaped pole seat 2 and the two shoe poles 3, and communicating with the second oil guide groove 35, the second groove 21 can also receive copper shavings and conductive oil falling from the inclined surface 31 of the shoe pole 3 through the first oil guide groove 32, making it convenient to collect conductive oil and copper shavings stuck to the inclined surface 31 of the conductive ring 4 and the shoe pole 3.
[0055] In some specific embodiments, the T-shaped base 2 can be made from a single piece of material into a T-shaped structure, or it can be made from multiple materials spliced together into a T-shaped structure.
[0056] In this application, the T-shaped pole base 2 is a T-shaped structure formed by splicing two columnar copper materials and is installed on the upper surface of the housing 1. The top of the T-shaped pole base 2 is connected to the shoe pole 3 by screws or rivets.
[0057] like Figure 1 As shown, in some specific embodiments, it also includes an oil receiving tank 6 and a second conduit 8; the bottom of the second groove 21 is provided with an oil guiding hole 22, and the oil receiving tank 6 and the second groove 21 are connected through the oil guiding hole 22 and the second conduit 8.
[0058] By setting up an oil receiving tank 6 and a second conduit 8, the oil receiving tank 6 and the second groove 21 are connected through the oil guide hole 22 at the bottom of the second groove 21 and the second conduit 8. During operation, conductive oil and copper shavings are collected from the first oil guide groove 32 and the second oil guide groove 35 into the second groove 21. Then, the collected conductive oil and copper shavings flow from the second groove 21 into the oil receiving tank 6 through the oil guide hole 22 and the second conduit 8, preventing environmental pollution and improving the service life of the conductive device.
[0059] like Figure 4 As shown, specifically, one side of the T-shaped base 2 is provided with a connecting hole 23, which communicates with the oil guide hole 22, and the connecting hole 23 is connected to the second conduit 8.
[0060] By providing a connecting hole 23 on one side of the T-shaped electrode base 2, which communicates with the oil guide hole 22 at the bottom of the second groove 21, and the second groove 21 having two corresponding first oil guide grooves 32 and second oil guide grooves 35 for the two shoe electrodes 3, and having two connecting holes 23 that communicate with the oil guide holes 22 at the bottom of the second groove 21, it is convenient to collect conductive oil and copper shavings into the oil receiving tank 6 through the oil guide holes 22. In this application, the second conduit 8 is connected to the two connecting holes 23, leading out two pipelines that communicate with the oil receiving tank 6, thereby improving the oil guiding efficiency.
[0061] The working principle of removing copper shavings through the above-mentioned conductive device is as follows: conductive oil flows from the bottom of the oil tank 5 through the first conduit 7 and drips quickly onto the upper surface of the conductive ring 4. This causes the copper shavings generated by the friction between the copper-tungsten sheet and the conductive ring 4 to fall into the first oil guide groove 32 of the inclined surface 31 under the action of the viscous flow of the conductive oil and the gravity of the copper shavings themselves, and then flow through the through hole 34 of the first groove 33 to the second oil guide groove 35 at the bottom of the shoe electrode 3. Then, it falls into the second groove 21 at the top of the T-shaped electrode 2. The copper shavings in the second groove 21 then flow with the conductive oil from the oil guide hole 22 of the T-shaped electrode 2 and the connecting hole 23 on the side wall to the second conduit 8, and finally fall into the oil receiving tank 6, thus realizing the function of removing copper shavings from the contact surface between the conductive ring 4 and the shoe electrode 3.
[0062] The specific embodiments of this application have been described above. It should be understood that this application is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this application. The above-described preferred features can be used in any combination without conflict.
