Description

Technical Field

[0001] This invention relates to the field of electrolytic copper foil production, specifically a mechanical shielding device for the bottom of the tank in an electrolytic copper foil production machine. Background Technology

[0002] In the electrolytic copper foil production process, the foil-forming machine is the core equipment; the cathode roller rotates in the electrolyte, and copper ions are reduced and deposited on the surface of the cathode roller to form copper foil. In order to ensure the quality of copper foil (such as thickness uniformity, low roughness, and no pinholes), a shielding device is usually required in the electrolytic cell to optimize the electric field distribution and electrolyte flow field; Existing tank bottom shielding devices mostly use an integral insulating plate fixed to the bottom of the tank. The integral shielding plate is fixed with bolts or weighed down with heavy objects. When it is necessary to clean the anode mud deposited at the bottom or replace damaged parts, the electrolyte in the tank must be drained, which is time-consuming and labor-intensive and seriously affects production efficiency. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, most existing tank bottom shielding devices use an integral insulating plate fixed to the bottom of the tank. Moreover, the integral shielding plate is fixed by bolts or weighed down by heavy objects. When it is necessary to clean the anode mud deposited at the bottom or replace damaged parts, the electrolyte in the tank must be drained, which is time-consuming and labor-intensive and seriously affects production efficiency. This invention proposes a mechanical shielding device for the bottom of the tank of an electrolytic copper foil production machine.

[0004] The technical solution adopted by this invention to solve its technical problem is: a mechanical shielding device for the bottom of a foil-forming machine tank, comprising a foil-forming machine tank body, an installation base fixedly connected to the inner wall of the foil-forming machine tank body, a docking rod fixedly connected to the top of the installation base, an isolation mechanism provided on the inner wall of the foil-forming machine tank body, the isolation mechanism comprising a magnetic base, the magnetic base being slidably connected to the surface of the docking rod, a pull rod slidably connected to the inner wall of the foil-forming machine tank body, a limit plate fixedly connected to one side of the pull rod, a spring provided on the surface of the pull rod, a slide table fixedly connected to one side of the foil-forming machine tank body, a sliding sleeve slidably connected to the inner wall of the slide table, and an insertion rod fixedly connected to one side of the sliding sleeve.

[0005] Preferably, a limit stop is fixedly connected to the surface of the pull rod, and the surface of the limit stop is slidably connected to the inner wall of the foil-making machine tank.

[0006] Preferably, a sealing gasket is fixedly connected to the inner wall of the foil-making machine tank, and the inner wall of the sealing gasket is slidably connected to the surface of the limiting plate.

[0007] Preferably, a magnet is fixedly connected to the inner wall of the mounting base, and the top of the magnet is magnetically attracted to the bottom of the magnetically conductive base.

[0008] Preferably, a fixed base frame is fixedly connected between the inner wall of the foil-making machine tank and the bottom of the mounting base, and one end of the insertion rod cooperates with the round hole on the surface of the pull rod.

[0009] Preferably, the top of the magnetic base is provided with a material lifting hole, and the bottom of the limiting plate is in close contact with the top of the magnetic base.

[0010] The advantages of this invention are: This invention, through an isolation mechanism, allows for the rapid replacement or cleaning of a single magnetic base without draining the electrolyte, preventing anode mud deposition and back-rolling, thus improving the surface smoothness of the copper foil. It solves the problem that existing bottom shielding devices often use integral insulating plates fixed to the bottom of the tank, and these integral shielding plates are fixed with bolts or weighed down with heavy objects. When cleaning the anode mud deposited at the bottom or replacing damaged parts, the electrolyte in the tank must be drained, which is time-consuming, labor-intensive, and seriously affects production efficiency.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail. This application discloses a mechanical shielding device for the bottom of the tank in an electrolytic copper foil production machine. (Refer to...) Figures 1-7A mechanical shielding device for the bottom of a foil-forming machine tank in electrolytic copper foil production includes a foil-forming machine tank 1. A mounting base 5 is fixedly connected to the inner wall of the tank 1. A connecting rod 2 is fixedly connected to the top of the mounting base 5. An isolation mechanism 8 is provided on the inner wall of the tank 1. The isolation mechanism 8 includes a magnetic base 805, which is slidably connected to the surface of the connecting rod 2. A pull rod 801 is slidably connected to the inner wall of the tank 1. A limit plate 804 is fixedly connected to one side of the pull rod 801. A spring 807 is provided on the surface of the pull rod 801. A slide table 806 is fixedly connected to one side of the tank 1. A sliding sleeve 803 is slidably connected to the inner wall of the slide table 806. A [missing information - likely a device or component] is fixedly connected to one side of the sliding sleeve 803. First, a person holds one end of the pull rod 801 and pulls it outward, causing the limiting plate 804 to retract inward. When one end of the insertion rod 802 aligns with the round hole on the surface of the pull rod 801, the insertion rod 802 is slid to lock into the round hole on the surface of the pull rod 801. Then, multiple magnetic bases 805 are sequentially installed on the surface of the mounting base 5. At the same time, the round holes at both ends of the magnetic base 805 are connected to the docking rod 2. Then, the insertion rod 802 is pulled outward, and the spring 807 releases its elastic force to push the limiting plate 804 to lock the magnetic base 805, thus completing the installation of the magnetic base 805. The gap between the multiple sets of magnetic bases 805 is related to the square hole on the surface of the magnetic base 805. With identical hole sizes, when the foil-making machine starts electrolysis, the rotating cathode roller drives the electrolyte flow. The insulating material of the magnetic base 805 effectively blocks stray currents in the bottom area of ​​the foil-making machine tank 1, ensuring that the electric field lines are evenly concentrated on the effective deposition surface of the cathode roller. This eliminates the uneven copper foil thickness caused by the tank bottom edge effect. When the electrolyte carrying bubbles and trace amounts of anode mud flow through the magnetic base 805, it is guided and constrained by the louvered inclined flow channel structure. The fluid is forced to accelerate and pass through the narrow channel, and the resulting shearing action breaks up the rising large bubbles, making it difficult for them to adhere to the cathode roller surface, thus avoiding pinhole defects. At the same time, the unidirectional flow design of the magnetic base 805 allows the electrolyte to eliminate stray currents in the foil-making machine tank. The bottom eddy current and flow dead zone of the tank 1 prevent anode mud from accumulating and rolling back directly below the cathode roller. When cleaning the magnetic base 805, only a portion of the electrolyte needs to be discharged, exposing the magnetic base 805. Then, the operator holds the pull rod 801 to move the limit plate 804 to release the magnetic base 805. The insertion rod 802 is then inserted into the round hole on the surface of the pull rod 801. The magnetic base 805 is then removed by hooking the material lifting hole 9 with an external tool. The replacement or cleaned magnetic base 805 is then installed on the surface of the docking rod 2. After pulling the insertion rod 802 to release the pull rod 801, the contracted spring 807 will overcome the tension and push the limit plate 804 to lock the magnetic base 805, thus completing the cleaning of the magnetic base 805.

[0016] Reference Figure 6A limiting baffle 3 is fixedly connected to the surface of the pull rod 801. The surface of the limiting baffle 3 is slidably connected to the inner wall of the foil-making machine tank 1. The limiting baffle 3 installed on the surface of the pull rod 801 can limit the range of movement of the limiting plate 804 in the foil-making machine tank 1 by moving in the groove of the foil-making machine tank 1. At the same time, it can prevent external dust or water from entering the groove of the foil-making machine tank 1 and affecting the components of the isolation mechanism 8. Reference Figure 6 A sealing gasket 7 is fixedly connected to the inner wall of the foil production machine tank 1. The inner wall of the sealing gasket 7 is slidably connected to the surface of the limiting plate 804. The sealing gasket 7 installed on the inner wall of the foil production machine tank 1 increases the sealing performance between the limiting plate 804 and the foil production machine tank 1. When the limiting plate 804 is in the process of locking the magnetic base 805, the sealing gasket 7 can isolate the electrolyte in the foil production machine tank 1 and prevent electrolyte leakage. Reference Figure 6 A magnet 6 is fixedly connected to the inner wall of the mounting base 5. The top of the magnet 6 is magnetically attracted to the bottom of the magnetic base 805. The magnet 6 installed on the inner wall of the mounting base 5 can increase the connection strength between the magnetic base 805 and the mounting base 5 by magnetically attracting the magnetic base 805, and assist the limiting plate 804 in fixing the magnetic base 805 in the groove of the mounting base 5. Reference Figure 2 and Figure 6 A fixed bottom frame 4 is fixedly connected between the inner wall of the foil-making machine tank 1 and the bottom of the mounting base 5. One end of the insertion rod 802 cooperates with the round hole on the surface of the pull rod 801. The fixed bottom frame 4 installed between the foil-making machine tank 1 and the mounting base 5 can increase the firmness of the mounting base 5 on the inner wall of the foil-making machine tank 1. During the installation of the magnetic base 805, it can prevent the magnetic base 805 from shifting and falling off. When it is necessary to remove the magnetic base 805, the pull rod 801 needs to be pulled outward, and then the insertion rod 802 is pinched so that one end is inserted into the round hole on the surface of the pull rod 801, which can temporarily support the pull rod 801. Reference Figure 4 and Figure 7 The top of the magnetic base 805 is provided with a material lifting hole 9. The bottom of the limiting plate 804 is in close contact with the top of the magnetic base 805. The material lifting hole 9 on the top of the magnetic base 805 allows the user to remove the magnetic base 805 for cleaning or replacement using an external tool when it needs to be replaced. When the magnetic base 805 is installed in the foil production machine tank 1, the limiting plate 804 will hold the magnetic base 805 in place under the elastic force of the spring 807, thus completing the installation of the magnetic base 805.

[0017] Working principle: First, the operator holds one end of the pull rod 801 and pulls it outward, causing the limiting plate 804 to retract inward. When one end of the insertion rod 802 aligns with the round hole on the surface of the pull rod 801, the sliding insertion rod 802 is locked into the round hole on the surface of the pull rod 801. Then, multiple magnetic bases 805 are sequentially installed on the surface of the mounting base 5. At the same time, the round holes at both ends of the magnetic base 805 are connected to the docking rod 2. Then, the insertion rod 802 is pulled outward, and the spring 807 releases its elastic force to push the limiting plate 804 to lock the magnetic base 805, thus completing the installation of the magnetic base. The installation of 805 involves multiple sets of magnetically conductive bases 805 with gaps matching the size of the square holes on the surface of the magnetically conductive base 805. When the foil-making machine starts electrolysis, the rotation of the cathode roller drives the electrolyte flow. The insulating material of the magnetically conductive base 805 effectively blocks stray currents in the bottom area of ​​the foil-making machine tank 1, ensuring that the electric field lines are evenly concentrated on the effective deposition surface of the cathode roller. This eliminates the uneven copper foil thickness caused by the edge effect at the bottom of the tank. When the electrolyte, carrying bubbles and trace amounts of anode mud generated by the anode, passes through the magnetically conductive base 805, it is guided and constrained by the louvered inclined flow channel structure, forcing the fluid to accelerate. The shearing action generated by the narrow channel breaks up the rising large air bubbles, making them difficult to adhere to the cathode roller surface and thus avoiding pinhole defects. Simultaneously, the unidirectional flow design of the magnetic base 805 eliminates eddies and dead zones at the bottom of the foil-making machine tank 1, preventing anode mud from accumulating and rolling back directly below the cathode roller. When cleaning the magnetic base 805, only a portion of the electrolyte needs to be drained, exposing the magnetic base 805. The operator then holds the pull rod 801, which drives the limit plate 804 to release the magnetic base 805. The insertion rod 802 is then inserted into the round hole on the surface of the pull rod 801, and then an external tool is used... Hook the material lifting hole 9 to remove the magnetic base 805, then replace or clean the magnetic base 805 and install it on the surface of the docking rod 2. Pull the insertion rod 802 to release the pull rod 801, and the retracted spring 807 will overcome the pulling force to push the limit plate 804 to lock the magnetic base 805, thus completing the cleaning of the magnetic base 805. It should be noted that the electrolysis operation and operation steps of the foil making machine are existing technical solutions. The core innovation of this solution is not in "how to perform electrolysis", but in "how the bottom shielding device of the tank can optimize the environment and solve maintenance problems through mechanical structure during the electrolysis process".
