Description

201012975 IX. Description of the Invention: [Technical Field] The present invention relates to a structure of an electrode substrate used in an apparatus for manufacturing an electrolytic metal foil. [Prior Art] The electrolytic metal foil manufacturing apparatus, as shown in the figure, immerses the conductive drum 1 in the electrolysis (4) 3 to make it (4), and serves as a cathode reading surface and an electrode substrate which is disposed in the electric β solution solution 3 and serves as an anode. Between 2, a direct current is flown, and an electrolytic metal foil layer is formed on the surface of the conductive drum 1 to manufacture an electrolytic metal foil. The electrode base 2 used in the above-described manufacturing apparatus is an object shown in Figs. 1 and 11 and is formed on the surface side (the side of the conductive drum i) of the anode base material 20 which is bent toward the conductive body. The object of the electrode plate. Moreover, a longitudinal bus bar for supplying current is mounted on the inner surface of the anode substrate 2〇.

The front longitudinal flow bar 40 shown in Fig. θ, Fig. η(1) and n(8) is such that the tip end portion 41 is interposed between the electrode plate 5 and the yoke 5, η is locked on the inner side surface of the anode substrate 2 . When the fixing method of the foregoing longitudinal manifold 4 is used, a contact resistance Ri is generated between the longitudinal bar 40 and the electrode plate 50, and a current-resistance R2 of the /electrode plate 50 and the electrode plate 5 and the anode are generated. The electric resistance R3 '' between the base material 2' is so large that the electric resistance is increased and the electric power loss is generated. The electrode plate 50 is connected to the electrode base 2〇 which is bent.

2048-9986-PF 5 201012975 It is often i~2, so the end of the bending direction is the base of the electrode base 20, and the negative resistance is longer, and the resistance is large. That is, the corrosion-resistant material is applied to the respective portions of the curved surface, so the electric power is large. As a result, there is a large difference in the distance between the overall average electric resistance plates 50, and at the same time, the current in each portion of the curved surface is uneven = power loss is reported, and the electrode plate 50 is also made of a resistor such as titanium. Therefore, the length of the circuit from which the electric power from the longitudinal flow bar flows in the lateral direction and the money transfer material is 20 will become longer, and the @electrode base body becomes larger and larger. As a result, the longitudinal flow in the vicinity of and around the rowing rod mounting portion becomes uneven. The present invention is based on the above problems and provides a method for dividing the electrode substrate into a plurality of divided electrodes. The base portion of the base body is fixed with a tip end portion of the longitudinal flow bar, and the tip end portion of the longitudinal flow bar is fixed to the horizontal flow bar, and the horizontal flow bar is fixed to the electrode base by bolts, whereby the electric contact resistance is small. An electrode substrate of an electrolytic metal foil manufacturing apparatus capable of preventing power loss. [Means for Solving the Problem] The gist of the present invention is a cylindrical cathode in which an electrode substrate of an electrolytic metal crucible manufacturing apparatus has a curved surface and faces an electrolytic metal (four) device, and a supply current is fixed to an inner surface thereof. a longitudinal bar 2 rod to the electrode substrate is characterized in that the electrode substrate is divided into a plurality of pieces and divided

2048-9986-PF 6 201012975 The tip end portion of the longitudinal flow bar is fixed to each of the electrode bases. The present invention is directed to an electrode substrate of an electrolytic metal foil, wherein the tip end portion of the longitudinal bar is fixed to a conductive cross bar, and the horizontal bar is fixed to an inner surface of the electrode substrate. According to the gist of the present invention, in an electrode substrate of an electrolytic metal foil manufacturing apparatus, a curved surface having the same curvature as that of the surface of the electrode substrate is formed on the surface of the tip end of the longitudinal flow bar, and the curved surface is closely adhered to the surface of the electrode substrate. . The gist of the present invention is a method in which an electrode base body of an electrolytic metal foil manufacturing apparatus fixes the longitudinal flow bar to an electrode base by bolts, and locks the intertwined gasket between the bolt and the longitudinal flow bar. . [Effect of the Invention] As described above, the electrode substrate is divided into a plurality of electrodes, and the tip end of the longitudinal bus bar is fixed to each of the divided electrode substrates so that the current distribution of the electrode substrate is uniform and average. The electric resistance Φ is reduced to prevent power loss, and current unevenness in each portion of the curved surface can be prevented, power supply can be efficiently performed, and the device can be easily assembled.

When the tip end portion of the longitudinal flow bar is fixed to the two bus bars fixed to the electrode substrate, the conductivity in the lateral direction is improved, so that the L bar is attached. The resistance around and off the P does not cause a difference in the current distribution between the anode substrate and the conductive drum in the lateral direction. In the case of the surface of the tip end of the longitudinal flow bar, Isaid constitutes the same as the surface of the electrode substrate. When the curved surface is fixedly fixed to the surface of the electrode base 2048-9986-PF 201012975, it will be from the longitudinal direction. The current resistance of the bus bar to the electrode base is reduced, and power supply can be prevented from being efficiently performed, and power supply can be efficiently performed. As in the previous example, the longitudinal bar is used without using an electrode plate on the electrode substrate, so the number of parts will change. Less, the manufacturing cost of the manufacturing device can be reduced and the manufacturing efficiency can be improved. When the longitudinal bus bar is bolted to the electrode base and locked by a curved gasket between the bolt and the longitudinal flow bar, the longitudinal flow bar can be more strongly fixed. [Embodiment] The best mode for carrying out the present invention is to divide a curved electrode substrate facing a cylindrical cathode (conductive drum) of an electrolytic metal falling device into a plurality of pieces, and at the same time, each of the longitudinal bars is separately The tip of each of the electrode bases is fixed to the conductive cross bar, and the cross bar is fixed to the inner surface of the electrode base.
