[0018] 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.

[0019] Example 1 refer to Figures 1-4 An online grinding device for a cathode roller 2 includes a machine base 1 and a first rotating mechanism 11 mounted on the machine base 1 for driving the cathode roller 2 to rotate. The cathode roller 2 is connected to the first rotating mechanism 11. The top of the machine base 1 is provided with a liquid storage tank 12 for accommodating the cathode roller 2. The device also includes a grinding roller 3 for grinding the cathode roller 2 and two mounting seats 4 mounted on the machine base 1. Both ends of the grinding roller 3 are fitted with bushings 31; the mounting base 4 has an accommodating opening 44, and both bushings 31 can be placed in the accommodating opening 44. One end of the grinding roller 3 is also provided with a first gear 32, and one side of the mounting base 4 is provided with a second rotating mechanism 7. The output end of the second rotating mechanism 7 is provided with a second gear 72. When the bushing 31 is placed in the receiving opening 44, the bushing 31 is limited by a limiting structure 6, and the first gear 32 meshes with the second gear 72. The rotating mechanism is used to drive the second gear 72 to rotate.

[0020] The first rotating mechanism 11 has been disclosed in Chinese patent CN202410456655.3, so the structure of the first rotating mechanism 11 will not be described in detail in this embodiment.

[0021] In this design, the two ends of the grinding roller 3 are fitted with bushings 31. When grinding the cathode roller 2, the worker places the two bushings 31 into the receiving openings 44 of the two mounting seats 4 respectively, so that the grinding roller 3 contacts the surface of the cathode roller 2, and the first gear 32 meshes with the second gear 72. Then, the bushings 31 are limited by the limiting structure 6. After that, the first rotating mechanism 11 and the second rotating mechanism 7 are started, so that the first rotating mechanism 11 drives the cathode roller 2 to rotate, and the second rotating mechanism 7 drives the grinding roller 3 to rotate to grind the cathode roller 2. When it is necessary to disassemble and replace the grinding roller 3, the second rotating mechanism 7 is stopped, and the limiting structure 6 is released from limiting the bushings 31, so that the worker can take out the grinding roller 3. In this way, it is more convenient and faster for the worker to disassemble and replace the grinding roller 3.

[0022] In this embodiment, the mounting base 4 has a U-shaped structure, and the opening of the mounting base 4 is an accommodating opening 44; The opening direction of the receiving opening 44 is opposite to that of the cathode roller 2.

[0023] Furthermore, the opening direction of the receiving opening 44 is turned away from the cathode roller 2, so that the worker can disengage the first gear 32 and the second gear 72 by rolling, so that the worker can remove the grinding roller 3.

[0024] Preferably, the mounting base 4 includes a first horizontal part 41, a vertical part 42 connected to the first horizontal part 41, and a second horizontal part 43 connected to the vertical part 42. The hand-tightening bolt 61 is vertically mounted on the first horizontal part 41 by means of screwing, and the second horizontal part 43 is connected to the machine base 1. The limiting structure 6 includes a hand-tightening bolt 61 and two limiting blocks 62. The hand-tightening bolt is set on the first horizontal part 41, and the two limiting blocks 62 are respectively set at both ends of the bushing 31. When the bushing 31 is placed in the receiving opening 44, the two limiting blocks 62 are respectively located on both sides of the receiving opening 44.

[0025] Specifically, the bolt is set vertically. The worker places the bushing 31 into the receiving opening 44 and engages the first gear 32 and the second gear 72, then tightens the hand-tightening bolt 61 to move it downwards. The hand-tightening bolt 61 prevents the bushing 31 from moving towards the opening of the receiving opening 44. Moreover, when the bushing 31 is placed in the receiving opening 44, the two limiting blocks 62 are located on both sides of the receiving opening 44. This restricts the movement of the grinding roller 3 in its own axial direction. By limiting the grinding roller 3 in this way, it can be ensured that the connection between the first gear 32 and the second gear 72 will not be broken during grinding.

[0026] Preferably, the first horizontal part 41 is located above the second horizontal part 43, the length of the second horizontal part 43 is longer than the length of the first horizontal part 41, and a nylon block is provided at the end of the second horizontal part 43 away from the cathode roller 2.

[0027] Specifically, the receiving opening 44 faces away from the cathode roller 2, and the length of the second horizontal part 43 is longer than the length of the first horizontal part 41. During disassembly, the worker tightens the hand-tightening bolt 61 to move the hand-tightening bolt 61 upward, and then the worker can roll the grinding roller 3 in the length direction of the second horizontal part 43 to roll the grinding roller 3 out. Then, by using inertia, the grinding roller 3 rolls to the baffle 45, and the baffle 45 stops the grinding roller 3. In this way, the disassembled grinding roller 3 is temporarily stored on the second horizontal part 43. Then the worker can install a new grinding roller 3 to replace the disassembled grinding roller 3 for grinding. This makes it convenient for the worker to install and disassemble.

[0028] More preferably, the machine base 1 is also provided with a drive mechanism 5, and both of the mounting bases 4 are connected to the drive mechanism 5. The drive mechanism 5 is used to drive the grinding roller 3 to move closer to or further away from the cathode roller 2. The drive mechanism 5 includes a frame 51, a sliding platform 56, and a sensor rail 55; the frame 51 is connected to the machine base 1, the sensor rail 55 is connected to the frame 51, the top of the frame 51 is provided with a groove 53, a screw 54 is provided in the groove 53, a drive motor 52 is provided on the sliding frame 51, and one end of the screw 54 is connected to the drive motor 52; The sliding platform 56 is slidably connected to the sensor guide rail 55. The bottom of the sliding platform 56 is provided with a slider, which is screwed to the screw 54. Two mounting seats 4 are arranged at intervals on the sliding platform 56, and a sensing plate 57 is provided on one side of the mounting seat 4.

[0029] For details on the specific structure and operation of the induction plate and sensor rail, please refer to the online cathode roller polishing mechanism and electrolytic copper foil copper production machine disclosed in Chinese patent CN220279279U.

[0030] The sensor 57 positions the mounting base 4 by cooperating with the sensor guide rail 55 and sends a signal to the peripheral PLC system. The peripheral PLC system controls the drive motor 52 to stop operating so that the grinding roller 3 can grind the cathode roller 2. The peripheral PLC system adopts a PLC system well known to those skilled in the art. Generally, the drive motor 52 drives the mounting base to move the grinding roller 3 towards the cathode roller 2 to grind the cathode roller. The time is recorded by the external PLC system. Each grinding of the cathode roller 2 lasts for 20 minutes. After grinding is completed, the external PLC system controls the drive motor 52 to drive the mounting base 4 to reset so that the grinding roller 3 can be removed. If the grinding effect is not good, the worker can disassemble and replace the grinding roller 3.

[0031] Preferably, the second rotating mechanism 7 includes a fixed base 71 and a rotary motor 73 mounted on the fixed base 71. The fixed base 71 is located on one side of the mounting base 4, and the second gear 72 is located on the output end of the rotary motor 73. After the bushing 31 is placed in the receiving opening 44 and the first gear 32 meshes with the second gear 72, the bushing 31 is limited by the limiting structure 6. Then, the rotary motor 73 drives the second gear 72 to rotate, thereby causing the first gear 32 to rotate, which in turn causes the grinding roller 3 to rotate.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of the present utility model, and these improvements or modifications should also be considered within the protection scope of the present utility model.
