Description

Technical Field

[0001] This utility model relates to the technical field of electrolytic copper foil production process equipment, specifically an automatic extrusion roller device for a foil production machine. Background Technology

[0002] Electrolytic copper foil production mainly consists of four processes: solution preparation, electrolysis, surface treatment, and slitting. The electrolysis process involves using a cathode roller, anode plate, and electrolytic cell. Under the influence of direct current, copper ions in the electrolyte move towards the cathode roller, undergoing a reduction reaction to form copper foil. After the copper foil exits the electrolytic cell with the cathode roller, an acid spray pipe is installed at the cell outlet to spray and wash the copper foil with electrolyte, removing surface deposits. Above the acid spray pipe is an acid squeezing roller to remove all electrolyte from the surface. Above the acid squeezing roller is a water spray pipe to spray and wash the copper foil with pure water. Above the water spray pipe is a water squeezing roller to remove all water from the surface.

[0003] Existing acid-squeezing and water-squeezing rollers directly fix the bearing seats on both sides of the cathode roller to the bracket. During roller adjustment, the acid-squeezing and water-squeezing rollers are pressed against the surface of the raw foil. After pre-fixing, the acid and water squeezing is observed, and the foil surface effect is confirmed before the bearing seats are fixed with screws. In actual operation, the pressure applied by the two ends of the rollers relies solely on the observation of the operators at both ends, which easily leads to inconsistencies, resulting in abnormalities such as color difference, acid lines, and water lines on the rough surface of the copper foil. Furthermore, this method requires a high level of skill from the operators and cannot achieve automated management or quantifiable standards. Utility Model Content

[0004] This invention provides an automatic extrusion roller device for a foil making machine, which can solve the problem that the pressure of the two ends of the acid extrusion roller and water extrusion roller is easily inconsistent when the operation is only observed by the operators at both ends.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic extrusion roller device for a foil production machine, comprising a slide rail arranged side-by-side on one radial side of the cathode roller, a sliding base provided at the upper end of the slide rail, and a drive unit installed on the upper side of the slide rail to push the sliding base to move along the slide rail. A water-squeezing roller, a water spray pipe, an acid-squeezing roller, and an acid spray pipe are sequentially and horizontally installed between the sliding bases from top to bottom. The outlet nozzles of the water spray pipe and the acid spray pipe face the cathode roller. The drive unit pushes the sliding base to move synchronously towards the cathode roller. By setting the drive unit and the slide rail, the sliding base can be driven to slide synchronously, thereby quickly realizing the forward and backward movement of the acid-squeezing roller and the water-squeezing roller, saving time and effort, simplifying operation, and solving the problem of inconsistent pressure on the two ends of the acid-squeezing roller and the water-squeezing roller.

[0006] Preferably, the driving unit is a cylinder, whose extension rod is connected to one end of the sliding base. The cylinder can control the contact pressure between the water squeezing roller and the acid squeezing roller and the cathode roller.

[0007] Preferably, the gas input end of the drive unit is equipped with a pressure gauge and a matching pressure valve, which allows for different pressure settings to correspond to foils of different thicknesses, ultimately enabling automated management.

[0008] Preferably, the sliding base is L-shaped, has a stable structure, and can slide stably along the slide rail.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] By setting up a drive unit and slide rail, the sliding base can be driven to slide synchronously, thereby quickly realizing the forward and backward movement of the acid squeezing roller and the water squeezing roller. This saves time and effort, is easy to operate, and solves the problem of inconsistent pressure on the two ends of the acid squeezing roller and the water squeezing roller.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] This invention addresses the problem that in existing acid squeezing rollers and water squeezing rollers, inconsistencies in the pressure applied to the two ends of the pressure rollers can easily occur if the operation relies solely on observation by the operators at both ends. For example... Figure 1-2 As shown, the following technical solution is provided: an automatic extrusion roller device for a foil making machine includes a slide rail 9, which is arranged side by side on one radial side of the cathode roller 1. A sliding base 4 is provided at the upper end of the slide rail 9. A drive unit 5 is installed on the upper side of the slide rail 9 to push the sliding base 4 to move along the slide rail 9. A water squeezing roller 2, a water spray pipe 6, an acid squeezing roller 3, and an acid spray pipe 7 are arranged horizontally from top to bottom between the sliding bases 4. The liquid spray holes of the water spray pipe 6 and the acid spray pipe 7 are arranged facing the cathode roller 1. The drive unit 5 pushes the sliding base 4 to move synchronously towards the cathode roller 1. By setting the drive unit 5 and the slide rail 9, the sliding base 4 can be driven to slide synchronously, thereby quickly realizing the forward and backward movement of the acid squeezing roller and the water squeezing roller, saving time and effort, and simplifying operation. This solves the problem of inconsistent pressure on the two ends of the acid squeezing roller and the water squeezing roller.

[0017] Specifically, the spacing between the slide rails 9 is greater than the width of the cathode roller 1. The two ends of the acid squeezing roller 3 and the water squeezing roller 2 are connected to the sliding base 4 by bearings. When the acid squeezing roller 3 and the water squeezing roller 2 come into contact with the cathode roller 1, they can rotate with the cathode roller 1. The drive unit 5 controls the rotation in a unified manner and can use common power components such as cylinders, oil cylinders, electric cylinders and gas springs.

[0018] Preferably, in this embodiment, the drive unit 5 is a cylinder, and its extension rod 8 is connected to one end of the sliding base 4. The cylinder can control the contact pressure between the water squeezing roller 2 and the acid squeezing roller 3 and the cathode roller 1. The gas input end of the drive unit 5 is equipped with a pressure gauge and a matching pressure valve, which can be used to adjust the pressure according to different foil thicknesses, and finally achieve automated management.

[0019] like Figure 1-2 As shown, the sliding base 4 is L-shaped and has a stable structure. The lower width of the sliding base 4 is greater than the upper width, allowing it to slide stably along the slide rail 9.

[0020] In this embodiment, as a specific experimental scheme, electrolytic copper foil is produced by electrochemical deposition. Its working principle involves using sulfuric acid and copper as the electrolyte. Under the action of direct current, cations move towards the cathode, and anions move towards the anode, depositing Cu on the cathode. 2+ The copper foil is reduced to Cu and uniformly deposited on cathode roller 1 to form copper foil, which is then wound up by peeling, while the acid and water squeezing roller device is installed above the copper foil outlet.

[0021] This embodiment presents an automatic extrusion roller device for a foil production machine. The foil production machine equipped with this automatic extrusion roller device is used to produce 18μm, 35μm, and 70μm foils according to normal processes. The cylinder pressure is adjusted, and the presence of acid channels and water channels on the foil surface is observed. The results are shown in Table 1 below.

[0022] Table 1 Results of Automatic Acid and Water Removal from Electrolytic Copper Foil

[0023]

[0024] As can be seen, the cylinder uses different air pressures to push the copper foil of three different thicknesses. Visually, the surface of the copper foil does not show acid channels or water channels.

[0025] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0026] Furthermore, in this utility model, descriptions involving terms such as "primary," "secondary," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "primary" or "secondary" may explicitly or implicitly include at least one of those features. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
