Description

Technical Field

[0001] This invention belongs to the field of cathode roller technology for foil making machines, and specifically relates to a device for stabilizing the operation of cathode rollers in foil making machines. Background Technology

[0002] The foil production machine is part of the copper foil production line. To prevent the rotating shaft on the cathode roller of the foil production machine from being worn during use, a lubricant is usually applied to the rotating support structure of the shaft.

[0003] Existing devices for stabilizing the operation of cathode rollers in foil-making machines can ensure stable bearing operation over long periods by applying lubricating oil to the balls between the inner and outer rings of the bearing. They also include protective structures between the inner and outer rings to prevent leakage. However, these protective structures are simply partitions fixed to the inner or outer ring of the bearing. This means that after a period of use, when the partitions become severely worn, users cannot quickly and easily replace them, thus failing to fully meet user needs. Summary of the Invention

[0004] In view of this, the present invention addresses the shortcomings of the prior art by providing a device for stabilizing the operation of the cathode roller of a foil-making machine. This device not only meets the basic requirement of assisting the stable operation of the cathode roller of the foil-making machine, but also allows users to easily replace the lubricant guard structure that has worn down to the point of being unusable, thereby more fully meeting people's usage needs.

A bearing seat is provided on the mounting seat, and a mounting shaft is rotatably disposed on the bearing seat through a support bearing. The mounting shaft is detachably connected to the rotating shaft. A first blocking component for locking and blocking one side of the support bearing is detachably disposed on the side of the bearing seat near the cathode roller, and a second blocking component for locking and blocking the other side of the support bearing is detachably disposed on the side of the bearing seat away from the cathode roller. A lubricating oil adding module is also provided on the second blocking component.

[0006] As a further improvement of the present invention, the top of the anode tank is provided with a mounting groove, the bottom of the mounting base is provided with a mounting slider that is slidably connected to the mounting groove, the mounting groove is provided with a fixing bolt for fixing the mounting slider, and the mounting slider is provided with a threaded fixing hole connected to the fixing bolt.

[0007] As a further improvement of the present invention, both the slot of the mounting groove and the vertical cross-section of the mounting slider are T-shaped.

[0008] As a further improvement of the present invention, a transmission slot is provided on the mounting shaft, and a transmission plug is provided on the rotating shaft to be inserted into the transmission slot. The transmission plug cannot rotate relative to the transmission slot.

[0009] As a further improvement of the present invention, the first blocking assembly includes a first mounting plate detachably connected to the bearing housing, a first through hole in the middle of the first mounting plate for engaging with the mounting shaft, a first blocking ring plate located outside the balls of the supporting bearing on the inner side wall of the first mounting plate, a first outer rubber sealing ring rotatably connected to the outer ring of the supporting bearing on the first blocking ring plate, and a first inner rubber sealing ring rotatably connected to the inner ring of the supporting bearing on the first blocking ring plate.

[0010] As a further improvement of the present invention, the second blocking assembly includes a second mounting plate detachably connected to the bearing housing. The second mounting plate has a second through hole in the middle for engaging with the mounting shaft. A second blocking ring plate located outside the balls of the supporting bearing is provided on the inner side wall of the second mounting plate. A second outer rubber sealing ring is provided on the second blocking ring plate and rotatably connected to the outer ring of the supporting bearing. A second inner rubber sealing ring is provided on the second blocking ring plate and rotatably connected to the inner ring of the supporting bearing.

[0011] As a further improvement of the present invention, a first mounting slot is provided on one side of the bearing housing, a first mounting plate is provided on the first mounting plate to engage with the first mounting slot, a first mounting bolt for screwing and fixing the first mounting plate is also provided on the first mounting slot, and a first mounting hole for connecting with the first mounting bolt is provided on the first mounting plate.

[0012] As a further improvement of the present invention, a second mounting slot is provided on the other side of the bearing housing, a second mounting plate is provided on the second mounting plate to engage with the second mounting slot, a second mounting bolt is also provided on the second mounting slot for screwing and fixing the second mounting plate, and a second mounting hole is provided on the second mounting plate to connect with the second mounting bolt.

[0013] As a further improvement of the present invention, the lubricating oil adding module includes an adding cavity disposed inside the second blocking ring plate, a feeding pipe connected to the adding cavity is disposed on the second mounting plate, a control valve is disposed on the feeding pipe, a plurality of adding pipes connected to the adding cavity are disposed on the inner side wall of the second blocking ring plate, and a coating brush that is misaligned with the adding pipe and adapted to the ball bearing of the supporting bearing is also disposed on the inner side wall of the second blocking ring plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: Firstly, by installing a smooth operation module at the top of the anode tank, the rotating shaft of the cathode roller is supported by a mounting base, bearing housing, and support bearing, effectively assisting the cathode roller to achieve stable operation and solving the vibration or instability problems that may occur during the operation of the foil-making machine. The device is designed with detachable first and second blocking components, which respectively clamp and block both sides of the support bearing. When the lubricant protection structure (such as rubber seals) wears to the point of being unusable, the user does not need to replace the entire bearing housing or the complex disassembly of the equipment; only the corresponding blocking component needs to be removed for replacement. This greatly reduces maintenance difficulty and cost, and extends the service life of the device.

[0015] Secondly, both the first and second plugging components are equipped with inner and outer rubber seals, which are rotatably connected to the inner and outer rings of the supporting bearing, respectively. This double-seal design effectively prevents external dust and impurities from entering the bearing, while also preventing internal lubricant leakage, ensuring the bearing operates in a clean environment and reducing wear. The second plugging component integrates a lubricant addition module, including an addition chamber, a feeding pipe, a control valve, and a spreading brush. Users can directly add lubricant to the bearing through the feeding pipe, and the spreading brush can evenly apply the lubricant to the balls, ensuring effective lubrication. This makes daily maintenance more convenient and quick, maintaining good lubrication without frequent disassembly of components.

[0016] Thirdly, the mounting base, through the T-shaped cross-section slider and the T-shaped groove at the top of the anode tank, not only restricts the mounting base from falling off, but also allows it to slide along the axis of the rotating shaft, making it easy to adjust the support position according to actual needs; with the fixing bolts and threaded holes, the adjusted mounting base can be firmly locked to prevent displacement during operation; the mounting shaft and the rotating shaft are connected by a transmission slot and a transmission plug to ensure that the two rotate synchronously without relative slippage, thus ensuring the stability of power transmission.

[0017] Fourth, the connection between the plugging component and the bearing housing adopts a "slot + plate + bolt" connection method. During installation, the plug is first snapped in for positioning and then screwed in for fixing. This ensures a tight connection and makes the disassembly and assembly process simple and quick, further improving maintenance efficiency. Attached Figure Description

[0022] like Figure 1 , 6 As shown, a smoothing device for the cathode roller of a foil-making machine is disclosed. A rotating shaft 102 is disposed through the cathode roller 101. A smoothing module for rotating the rotating shaft 102 is disposed at the top of the anode groove 103.

A lubricating oil adding module is also disposed on the second blocking component.

[0023] like Figure 1 , 2 As shown, the top of the anode groove 103 is provided with a mounting groove 204, and the bottom of the mounting base 201 is provided with a mounting slider 205 that is slidably connected to the mounting groove 204. The mounting groove 204 is provided with a fixing bolt 206 for fixing the mounting slider 205, and the mounting slider 205 is provided with a threaded fixing hole for connecting to the fixing bolt 206. The groove of the mounting groove 204 and the vertical section of the mounting slider 205 are both T-shaped.

[0024] like Figure 1 , 2 As shown, a transmission slot 207 is provided on the mounting shaft 203, and a transmission plug 208 is provided on the rotating shaft 102 to be inserted into the transmission slot 207. The transmission plug 208 cannot rotate relative to the transmission slot 207.

[0025] like Figure 2 , 3 As shown, the first blocking assembly includes a first mounting plate 301 detachably connected to the bearing housing 202. The first mounting plate 301 has a first through hole 302 in the middle that fits and connects with the mounting shaft 203. A first blocking ring plate 303 located outside the balls of the support bearing 104 is provided on the inner side wall of the first mounting plate 301. A first outer rubber sealing ring 304 rotatably connected to the outer ring of the support bearing 104 is provided on the first blocking ring plate 303. A first inner rubber sealing ring 305 rotatably connected to the inner ring of the support bearing 104 is provided on the first blocking ring plate 303.

[0026] like Figure 4 As shown, the second blocking assembly includes a second mounting plate 401 detachably connected to the bearing housing 202. The second mounting plate 401 has a second through hole 402 in the middle that is fitted and connected to the mounting shaft 203. A second blocking ring plate 403 located outside the balls of the support bearing 104 is provided on the inner side wall of the second mounting plate 401. A second outer rubber sealing ring 404 rotatably connected to the outer ring of the support bearing 104 is provided on the second blocking ring plate 403. A second inner rubber sealing ring 405 rotatably connected to the inner ring of the support bearing 104 is provided on the second blocking ring plate 403.

[0027] like Figure 2 , 3 As shown, a first mounting slot 501 is provided on one side of the bearing housing 202, a first mounting plate 502 is provided on the first mounting plate 301 to engage with the first mounting slot 501, a first mounting bolt 503 is provided on the first mounting slot 501 for screwing and fixing the first mounting plate 502, and a first mounting hole 504 is provided on the first mounting plate 502 to connect with the first mounting bolt 503.

[0028] like Figure 2 , 4 As shown in Figure 5, a second mounting slot 601 is provided on the other side of the bearing housing 202. A second mounting plate 602 is provided on the second mounting plate 401 to engage with the second mounting slot 601. A second mounting bolt 603 for screwing and fixing the second mounting plate 602 is also provided on the second mounting slot 601. A second mounting hole 604 for connecting with the second mounting bolt 603 is provided on the second mounting plate 602.

[0029] like Figure 4 As shown, the lubricating oil adding module includes an adding cavity 701 disposed inside the second blocking ring plate 403, a feeding pipe 702 connected to the adding cavity 701 disposed on the second mounting plate 401, a control valve 703 disposed on the feeding pipe 702, a plurality of adding pipes 704 connected to the adding cavity 701 disposed on the inner side wall of the second blocking ring plate 403, and a coating brush 705 disposed on the inner side wall of the second blocking ring plate 403, which is misaligned with the adding pipes 704 and adapted to the balls of the support bearing 104.

[0030] The working principle of the smooth operation device for the cathode roller 101 of the foil production machine is as follows: The user can first insert the T-shaped slider at the bottom of the mounting base 201 of the stable operation module into the T-shaped mounting groove 204 at the top of the anode tank 103. Slide the mounting base 201 along the axial direction of the rotating shaft 102 to move it to the desired support position; after the position is determined, tighten the fixing bolt 206 on the mounting groove 204 so that it is screwed into the threaded fixing hole on the mounting slider 205, thereby firmly locking the mounting base 201 and preventing it from shifting during subsequent operation; align the "transmission insert 208" at the end of the rotating shaft 102 of the cathode roller 101 with the "transmission slot 207" on the mounting shaft 203 and insert it. Since the two fit tightly and cannot rotate relative to each other, the rotating shaft 102 and the mounting shaft 203 are synchronously connected.

[0031] The first mounting plate 502 of the first blocking component is inserted into the first mounting groove 501 of the bearing housing 202, and the first sealing ring plate is simultaneously engaged with the inner and outer rings of the bearing. The first sealing ring plate is connected to the inner side of the bearing by the first outer rubber sealing ring 304 and the first inner rubber sealing ring 305. Then, the first mounting bolt 503 passes through the side wall of the first mounting groove 501 and connects with the first mounting hole 504, thereby completing the sealing of the side near the cathode roller 101. Then, the "second mounting plate 602" of the second blocking assembly is inserted into the "second mounting groove 601" of the bearing housing 202, simultaneously engaging the second sealing ring plate with the inner and outer rings of the bearing. A sealing rotational connection between the second sealing ring plate and the inner side of the bearing is achieved through the second outer rubber sealing ring 404 and the second inner rubber sealing ring 405. Then, the second mounting bolt 603 passes through the side wall of the second mounting groove 601 and connects to the second mounting hole 604, completing the sealing of the side away from the cathode roller 101. At this point, the support bearing 104 is completely enclosed between the first blocking assembly and the first blocking assembly.

[0032] After the foil-making machine is started, the drive mechanism (not shown in the figure) drives the rotating shaft 102 to rotate. The rotating shaft 102 drives the mounting shaft 203 to rotate through the transmission insert 208. The mounting shaft 203 rotates smoothly on the support bearing 104 in the bearing housing 202. The entire smooth operation module provides stable radial support for the rotating shaft 102, effectively suppressing vibration. During rotation, the first inner rubber seal 305 and the first outer rubber seal 304 on the first blocking assembly are in close contact with the inner ring of the support bearing 104, and the second inner rubber seal 405 and the second outer rubber seal 404 on the second blocking assembly are in close contact with the outer ring of the support bearing 104, achieving rotational sealing of the support bearing 104. This dynamic sealing structure blocks external dust and impurities from entering the bearing in real time, while preventing internal lubricating oil from leaking out, keeping the internal environment of the bearing clean.

[0033] When lubricating oil needs to be replenished, the operator opens the control valve 703 of the feed pipe 702 on the second plugging assembly. Lubricating oil flows through the feed pipe 702 into the adding chamber 701 inside the second plugging ring plate 403, and then through multiple adding pipes 704 to the bearing area. The flowing lubricating oil comes into contact with the "spreading brush 705" that rotates with the bearing balls. The spreading brush 705 evenly spreads the lubricating oil on the surface of the balls supporting the bearing 104, ensuring continuous and good lubrication. After completion, the control valve 703 is closed.

[0034] When a decrease in sealing performance is detected (such as oil leakage or dust ingress), the mounting bolts on the corresponding side (first or second) can be loosened to separate them from the threaded mounting holes. This allows the mounting slider 205 and mounting base 201 to slide away from the cathode roller 101 relative to the mounting groove 204. This separates the transmission slot 207 from the transmission insert 208 and the rotating shaft 102 from the mounting shaft 203. Subsequently, the first mounting bolt 503 can be separated from the first threaded mounting hole, and the first mounting plate 301 and the first plugging ring plate 303 can be separated from the support bearing 104. Then, the damaged first outer rubber seal 304 and the first inner rubber seal 305 can be disassembled and replaced. After that, the second mounting bolt 603 can be separated from the second threaded mounting hole, and the second mounting plate 401 and the second plugging ring plate 403 can be separated from the support bearing 104. Finally, the damaged second outer rubber seal 404 and the second inner rubber seal 405 can be disassembled and replaced.

[0035] During the replacement of the rubber seal ring, the support base can be used to support both sides of the rotating shaft 102 to prevent the rotating shaft 102 and the cathode roller 101 from being tilted due to uneven force. After that, the support base can be removed.

[0036] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
