Description

Technical Field

[0001] This utility model relates to the field of cathode roller structure technology, and in particular to a cathode roller structure for a foil production machine. Background Technology

[0002] The cathode roller of the copper foil production machine is a core piece of equipment in the electrolytic copper foil production process (i.e., the "green foil" process). Its main function is to act as a cathode carrier in the electrolytic cell, allowing copper ions in the electrolyte to deposit on its surface through an electrochemical reaction, forming a continuous and uniform copper foil substrate. It is usually a high-precision cylindrical component made of titanium alloy (or a metal roller with a surface coating of inert metals such as ruthenium or iridium), possessing excellent conductivity, corrosion resistance, and surface smoothness. The former ensures a stable and efficient electrolysis process, while the latter directly determines the surface flatness and thickness uniformity of the generated copper foil. During operation, the cathode roller rotates slowly and uniformly under the drive system. Copper ions are reduced to metallic copper on its surface and gradually accumulate into foil. Once the copper foil reaches the target thickness, it is continuously peeled off from the roller surface by a peeling mechanism and enters subsequent processing steps, ultimately forming the raw copper foil (i.e., "green foil") required by industry.

[0003] In the operation of foil-making machines, the sealing process plays a crucial role in ensuring the stability of the electrolysis process and the quality of the product. A good seal prevents electrolyte leakage and avoids external impurities from entering the electrolytic cell, thus ensuring that the electrolysis reaction takes place in a stable and pure environment.

[0004] In the prior art, Chinese utility model patent with publication number "CN220166298U" and patent name "A sealing device for an anode groove" discloses a cathode roller structure for a foil production machine. The patent describes a technical solution that "by inserting a clamping rod into the clamping hole on the sealing ring, the sealing ring can be restricted in the mounting groove. Through the cooperation between the sealing ring and the sealing groove, a sealing effect can be achieved in the anode groove. When the clamping rod is pushed out of the clamping hole, the restriction on the sealing ring can be released, and a sealing ring of appropriate size can be replaced. This allows the sealing ring to better cooperate with the sealing groove on the adjusted anode plate, thereby ensuring the sealing effect of the anode groove."

[0005] While this technical solution allows for convenient fixing of the sealing ring on the cathode roller, in actual use, when the sealing ring needs to be removed, multiple workers need to operate the lever simultaneously to move the slider and the locking rod out of the locking hole to complete the removal of the sealing ring. This operation not only consumes a lot of manpower but also increases the difficulty of disassembly. When installing the sealing ring, it is difficult to ensure that the locking hole and the locking rod are precisely aligned after the sealing ring is installed in the mounting groove. Workers need to constantly adjust the position of the sealing ring and try repeatedly to get the locking rod and the locking hole to fit correctly. The operation is not only cumbersome, but frequent disassembly and replacement of the sealing ring is unavoidable in the production process, which reduces work efficiency and makes it inconvenient to quickly disassemble and assemble the sealing ring on the cathode roller.

[0006] Therefore, in order to solve the above-mentioned technical problems, this utility model proposes a cathode roller structure for a foil production machine. Utility Model Content

[0007] The main objective of this invention is to provide a cathode roller structure for a foil production machine, which can effectively solve the problems in the background art.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A cathode roller structure for a foil production machine includes a roller body and sealing end rings disposed at both ends of the roller body;

[0010] The roller body is coaxially mounted with idler rollers at both ends, and a movable ring is sleeved on the outside of the idler roller. An adjusting component is provided on the outside of the idler roller to control the horizontal movement of the movable ring.

[0011] The roller body has symmetrical movable openings on both ends of the roller body. A fixed rod is fixedly connected inside the movable opening. A retaining sleeve is fitted outside the fixed rod. The fixed rod is inserted into a retaining hole corresponding to the inner wall of the sealing end ring. An elastic element for elastic reset of the retaining sleeve is provided outside the fixed rod.

[0012] The caliper and the movable ring are movably connected by a connector.

[0013] Furthermore, the adjusting component includes a knob, the inner wall of which has an internal thread, and the outer wall of the idler roller has an external thread for threaded connection of the knob. A groove is provided on the side of the knob near the movable ring, and a connecting ring is fixedly connected to the inner wall of the groove. The movable ring is fitted onto the outside of the idler roller, and an annular groove for rotatable connection of the connecting ring is provided on the outer wall of the movable ring.

[0014] Furthermore, the knob is ring-shaped.

[0015] Furthermore, the elastic element includes a spring, which is fitted outside the fixed rod. One end of the spring is fixedly connected to the bottom end of the movable opening, and the other end of the spring is fixedly connected to the bottom end of the clamping cylinder. The outer wall of the roller body has mounting grooves at both ends for installing the sealing end ring, and the groove wall of the mounting groove has through holes for the clamping cylinder to move up and down.

[0016] Furthermore, the connector includes a concave block and a connecting rod. Corresponding concave blocks are fixedly connected to the outer walls of the clamp and the movable ring. Rotating holes are provided on both sides of the concave block. A set of rotating rods are fixedly connected to both ends of the connecting rod and are rotatably connected to the rotating holes.

[0017] Furthermore, the mounting groove has two positioning holes on its wall, which are staggered with the through hole. The inner wall of the sealing end ring is equipped with a positioning block that matches the positioning holes, which is used to position the sealing end ring in the mounting groove.

[0018] Furthermore, the card hole and the positioning block are staggered.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] By designing a structure that combines adjusting components, movable rings, connecting components, and elastic components, the problem of cumbersome, labor-intensive, and inefficient disassembly and assembly of the traditional cathode roller sealing end ring is effectively solved. When disassembling the sealing end ring, multiple workers do not need to operate simultaneously. Simply turn the knob on the roller to move the movable ring horizontally via the connecting ring. Then, the connecting component pulls the clamp along the fixed rod to compress the spring, causing the clamp to disengage from the clamping hole of the sealing end ring. A single person can quickly complete the disassembly, reducing labor costs and disassembly difficulty.

[0021] During installation, the positioning port in the mounting slot cooperates with the positioning block of the sealing end ring to quickly and accurately position the sealing end ring, so that the clamping hole and the clamping sleeve are automatically aligned. With the elastic reset action of the spring, the clamping sleeve can automatically insert into the clamping hole to complete the fixation, so as to facilitate the quick installation and removal of the sealing end ring without repeated adjustments and attempts. This greatly simplifies the operation steps, reduces manpower input, and thus improves the installation and removal efficiency of the sealing end ring and the overall production efficiency.

[0029] 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.

[0030] like Figure 1 - Figure 6 As shown, a cathode roller structure for a foil production machine includes a roller body 1 and sealing end rings 3 disposed at both ends of the roller body 1;

[0031] Roller 2 is coaxially mounted on both ends of roller body 1. A movable ring 15 is sleeved on the outside of roller 2. An adjusting component is provided on the outside of roller 2 to control the horizontal movement of movable ring 15.

[0032] The roller body 1 has symmetrical movable openings 6 on both ends of the roller body 1. A fixed rod 19 is fixedly connected inside the movable opening 6. A retaining sleeve 21 is fitted outside the fixed rod 19. The fixed rod 19 is inserted into the retaining hole 10 corresponding to the inner wall of the sealing end ring 3. An elastic element for the retaining sleeve 21 to elastically reset is provided outside the fixed rod 19.

[0033] The locating cylinder 21 and the movable ring 15 are movably connected by a connector.

[0034] like Figure 2 and Figure 4 - Figure 6As shown, the adjusting component includes a knob 11, which is annular in shape and is used to fit the idler roller 2. The inner wall of the knob 11 is provided with an internal thread 12, and the outer wall of the idler roller 2 is provided with an external thread 8 for threaded connection of the knob 11. A groove 13 is provided on the side of the knob 11 near the movable ring 15. A connecting ring 14 is fixedly connected to the inner wall of the groove 13. The movable ring 15 is fitted on the outside of the idler roller 2. An annular groove 16 is provided on the outer wall of the movable ring 15 for rotatable connection of the connecting ring 14. When the operator rotates the knob 11, the threaded drive will drive the knob 11 to move horizontally along the axis of the idler roller 2. Since the connecting ring 14 can rotate freely in the annular groove 16, the rotation of the knob 11 will not drive the movable ring 15 to rotate synchronously. Only the connecting ring 14 can apply a horizontal pushing or pulling force to the movable ring 15, thereby controlling the movable ring 15 to move smoothly along the outer wall of the idler roller 2.

[0035] like Figure 2 As shown in the figure, the elastic element includes a spring 20, which is fitted on the outside of the fixed rod 19. One end of the spring 20 is fixedly connected to the bottom end of the movable opening 6, and the other end of the spring 20 is fixedly connected to the bottom end of the clamping cylinder 21. The outer wall of the roller body 1 has mounting grooves 4 for installing the sealing end ring 3 at both ends. The groove wall of the mounting groove 4 has a through hole 7 for the clamping cylinder 21 to move up and down. When the clamping cylinder 21 is pushed and moves upward along the fixed rod 19 through the through hole 7, it will force the spring 20 to perform an elastic extension operation. When the clamping cylinder 21 is no longer pushed, the spring 20 performs an elastic contraction operation and drives the clamping cylinder 21 into the movable opening 6 to achieve reset.

[0036] like Figure 4 As shown, the connector includes a concave block 17 and a connecting rod 22. Corresponding concave blocks 17 are fixedly connected to the outer walls of the clamping cylinder 21 and the movable ring 15. Rotating holes 18 are opened on both sides of the concave opening of the concave block 17. A set of rotating rods 23 are fixedly connected to both ends of the connecting rod 22 and are rotatably connected to the rotating holes 18. When the movable ring 15 moves horizontally along the roller 2, it will drive the concave block 17 on its outer wall to move synchronously. Through the cooperation of the rotating holes 18 and the rotating rods 23, the connecting rod 22 is pushed or pulled, thereby converting the horizontal movement into a vertical pulling or pushing force on the clamping cylinder 21, so that the clamping cylinder 21 moves up and down along the fixed rod 19 to clamp and fix the sealing end ring 3 or to contact the restriction of the sealing end ring 3.

[0037] like Figure 2 and Figure 3As shown, two positioning holes 5 are provided on the wall of the mounting groove 4 and are staggered with the through hole 7. The inner wall of the sealing end ring 3 is equipped with a positioning block 9 that matches the positioning hole 5. The positioning block 9 is used to position the sealing end ring 3 in the mounting groove 4. The locking hole 10 is staggered with the positioning block 9. When installing the sealing end ring 3, the positioning block 9 of the sealing end ring 3 is aligned and locked into the positioning hole 5 of the mounting groove 4. The circumferential rotation and radial displacement of the sealing end ring 3 can be restricted by the cooperation between the positioning block 9 and the positioning hole 5. At the same time, due to the staggered design, it can be ensured that after the positioning block 9 is locked, the locking hole 10 of the sealing end ring 3 is exactly aligned with the through hole 7 of the mounting groove 4, which is ready for the locking cylinder 21 to be inserted into the locking hole 10.

[0038] The specific operating principle of the cathode roller structure of this foil-making machine is as follows:

[0039] Align the sealing end ring 3 with the annular mounting grooves 4 at both ends of the roller body 1, so that the positioning block 9 on the inner wall of the sealing end ring 3 precisely engages with the positioning opening 5 on the groove wall of the mounting groove 4. Through the cooperation of the positioning block 9 and the positioning opening 5, the initial positioning of the sealing end ring 3 on the roller body 1 is quickly completed, ensuring that the position of the locking hole 10 on the inner wall of the sealing end ring 3 is aligned with the position of the through hole 7 on the groove wall of the mounting groove 4. Rotate the knob 11 located outside the idler roller 2. The knob 11 will rotate along the external thread 8 on the idler roller 2 through the internal thread 12 and move horizontally towards the side of the idler roller 2. The connecting ring 14 in the groove 13 on one side of the knob 11 will rotate in the annular groove 16 on the outer wall of the movable ring 15 under the drive of the knob 11, and simultaneously push the movable ring 15 to move on the idler roller 2. At this time, because the locking cylinder 21 and the movable ring 15 are connected by the connecting rod 22, and the two sides of the connecting rod 22 are connected by the connecting rod 22, the initial positioning of the sealing end ring 3 on the roller body 1 is completed. The rotating rod 23 at the end is rotatably connected to the rotating holes 18 on both sides of the recess of the concave block 17 installed on the movable ring 15 and the clamping cylinder 21. Therefore, after the movable ring 15 is horizontally displaced, the connecting rod 22 will be forced to tilt. The angle formed between the connecting rod 22 and the end face of the roller 2 will gradually increase. The connecting rod 22 pushes the clamping cylinder 21 to move along the movable ring 15 in the movable opening 6. The clamping cylinder 21 will gradually move out of the movable opening 6 through the through hole 7. The spring 20 at the bottom of the clamping cylinder 21 will be forced to perform an elastic extension operation under the movement of the clamping cylinder 21 until the clamping cylinder 21 passes through the through hole 7 and is inserted into the clamping hole 10 opened in the inner wall of the sealing end ring 3. The knob 11 can no longer be rotated. The sealing end ring 3 can then be installed at one end of the roller body 1. Finally, the installation of the sealing end ring 3 at the other end of the roller body 1 can be completed in the above manner.

[0040] When disassembling the sealing end ring 3, rotate the knob 11 in the opposite direction to move the knob 11 away from the end face of the roller body 1. The knob 11 drives the movable ring 15 to move synchronously through the connecting ring 14. The connecting rod 22 tilts and the angle between it and the end face of the roller body 1 increases. It also drives the clamping cylinder 21 to move inward through the concave block 17. At the same time, the spring 20 will perform an elastic compression operation, so that the clamping cylinder 21 passes through the through hole 7 and enters the movable port 6. After it is removed from the clamping hole 10, the sealing end ring 3 can be removed from the mounting grooves 4 at both ends of the roller body 1. This makes it easy to disassemble and assemble the sealing end ring 3 in the cathode roller structure of the foil making machine.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
