Description

Technical Field

[0001] This invention belongs to the field of cathode roller polishing technology, specifically, it relates to a cathode roller polishing device with cathode roller edge protection. Background Technology

[0002] In the field of cathode roller polishing, edge protection of the cathode roller is a crucial step in ensuring the processing quality. As a vulnerable area, the edge of the cathode roller is prone to wear, scratches, and corrosion if not properly protected, directly affecting the overall precision and service life of the cathode roller, and consequently impacting the processing quality of subsequent products. Therefore, reasonable and effective edge protection is essential for cathode roller polishing. Furthermore, to improve the polishing uniformity and processing quality of the cathode roller surface, existing polishing equipment typically features a function that allows for switching between forward and reverse rotation directions of the polishing roller. By changing the rotation direction, it adapts to different polishing conditions and cathode roller processing requirements, reducing problems such as uneven surface texture and polishing dead corners caused by polishing in a single rotation direction.

[0003] However, in practical applications, existing polishing equipment has been found to have a fixed water flow direction in its polishing slurry delivery system. When the polishing roller switches between forward and reverse rotation, the fixed water flow direction frequently opposes the rotation direction of the polishing roller. This not only leads to severe splashing of the polishing slurry and waste, but also prevents the slurry from evenly covering the polishing area, resulting in localized dryness and uneven polishing, which in turn affects the surface finishing accuracy of the cathode roller. At the same time, the reverse water flow cannot effectively remove the debris generated during the polishing process. The remaining debris will accelerate the wear on the surfaces of the polishing roller and cathode roller, shorten the service life of equipment components, and increase equipment maintenance costs.

[0004] In view of this, the present invention is proposed. Summary of the Invention

A threaded rod is screwed onto the side wall of the frame, and the end of the threaded rod is rotatably connected to a baffle.

The rotating shaft passes through the bracket and the output end of the rotating shaft is connected to the rotation center of the polishing roller. A controller is also installed on the side wall of the frame. The controller is used to control the start and stop of the drive assembly, the displacement assembly, the hydraulic push rod and the polishing motor.

[0012] In a preferred embodiment of the present invention, a water inlet pipe is installed at the bottom of the flow divider, the water inlet pipe is connected to the polishing fluid delivery system, a connecting cavity is opened at the bottom of the flow divider plug, and the connecting cavity is always connected to the water inlet pipe and the flow divider cavity is connected to each other, and the flow divider is connected to the end of the wind hood.

[0013] In a preferred embodiment of the present invention, a guide block is installed at the end of the shroud, a guide rail is provided at the end of the polishing roller, the guide block is slidably connected to the guide rail, a first air outlet is provided at one end of the shroud, a second air outlet is provided at the other end of the shroud, the fan blade is located between the first air outlet and the second air outlet, and the first air outlet and the second air outlet are located on both sides of the narrow channel, and a connecting shaft is installed at the rotation center of the fan blade, and the connecting shaft is connected to the rotation center of the polishing roller.

[0015] In a preferred embodiment of the present invention, a limiting plate is installed at the end of the limiting rod, the diameter of the limiting plate is larger than the diameter of the limiting rod, and a limiting spring is sleeved on the outer wall of the limiting rod. One end of the limiting spring is engaged with the side wall of the limiting plate, and the other end of the limiting spring is engaged with the side wall of the piston. The limiting spring is used to limit the initial position of the piston.

[0016] Compared with the prior art, the present invention has the following advantages: This invention utilizes a linkage structure formed by the rotation of the polishing roller, which drives the fan blades, piston, and flow divider to achieve synchronous switching of the gooseneck tube and precise adaptation of the water flow direction and the rotation direction of the polishing roller. When the polishing roller rotates clockwise or counterclockwise, its rotation center drives the fan blades inside the shroud to rotate synchronously via the connecting shaft. The rotation of the fan blades changes the air pressure inside the shroud, which in turn drives the piston on the narrow channel to slide. The piston, in conjunction with the flow divider, moves synchronously within the flow divider shroud, allowing the flow divider's chamber to precisely align with the corresponding gooseneck tube, thus switching the working state of the gooseneck tube and ultimately ensuring that the water flow direction is consistent with the rotation direction of the polishing roller. This structure solves the defect of fixed water flow direction when the polishing roller switches between forward and reverse directions, reduces polishing fluid splashing and uneven coverage of the polishing area, significantly improves the uniformity and processing accuracy of the cathode roller surface polishing, and ensures stable polishing quality. Furthermore, the water flow direction adaptation reduces the ineffective consumption of polishing fluid, avoids resource waste, and lowers the cost of polishing fluid replenishment and related production costs.

[0017] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention. Example 1:

[0021] like Figures 1 to 9 As shown, a cathode roller polishing device with cathode roller edge protection includes a frame 1.

[0022] A cathode roller 2 is mounted on the frame 1, and a drive assembly for driving the cathode roller 2 to rotate is mounted on the frame 1. A baffle 15 is movably inserted into the side wall of the frame 1, and the baffle 15 is attached to the edge of the cathode roller. A base 17 is mounted on the frame 1, a shifting component is mounted on the base 17, and a bracket 24 is mounted on the output end of the shifting component. A polishing roller 27 is rotatably mounted on the bracket 24. The shifting component is used to drive the polishing roller 27 to move along the surface of the cathode roller 2. A flow divider 40 is mounted on the support 24, and a pair of gooseneck tubes 42 are mounted on the flow divider 40. The output ends of the pair of gooseneck tubes 42 face the polishing position and are used to deliver polishing liquid from different directions. A fan shroud 28 is also mounted on the support 24. The fan shroud 28 wraps around the outer wall of the fan blade 32 mounted at the rotation center of the polishing roller 27. A narrow channel 35 is opened inside the fan shroud 28, and a piston 36 is slidably mounted on the narrow channel 35. The piston 36 is connected to the flow divider plug 43 installed in the inner cavity of the flow divider 40. The flow divider plug 43 is provided with a flow divider cavity 46 adapted to the gooseneck tube 42. When the rotation direction of the polishing roller 27 changes, the airflow pressure drives the piston 36 to move, so that the flow divider plug 43 slides synchronously and opens the corresponding gooseneck tube 42.

[0023] like Figures 1 to 9 As shown, in a specific embodiment, a bearing seat 3 is installed at one end of the frame 1, and the bearing seat 3 is rotatably connected to the main shaft on one side of the cathode roller 2. A fixed seat 6 is installed at the other end of the frame 1, and a synchronous shaft 5 is rotatably installed on the fixed seat 6. A fixed disk 4 is installed at the end of the synchronous shaft 5, and the fixed disk 4 is connected to the connecting flange at the end of the main shaft on the other side of the cathode roller 2. The drive assembly is used to drive the synchronous shaft 5 to rotate synchronously. Through the cooperation of the bearing seat 3, the fixed seat 6, the synchronous shaft 5, and the fixed disk 4, the cathode roller 2 is stably installed and positioned on the frame 1, ensuring the coaxiality of the cathode roller 2 during rotation, avoiding polishing deviations caused by unstable installation, and providing a reliable transmission path for the drive assembly to drive the cathode roller 2 to rotate.

[0024] like Figures 1 to 9As shown, the drive assembly further includes a drive motor 10, the housing of which is mounted on the side wall of the frame 1. A small pulley 8 is mounted on the output end of the drive motor 10, and a large pulley 7 is mounted on the end of the synchronous shaft 5. A belt 9 is fitted between the large pulley 7 and the small pulley 8. A protective cover 11 is mounted on the side wall of the frame 1, covering the outer walls of the large pulley 7 and the small pulley 8. This structure enables smooth driving of the cathode roller 2, while the protective cover 11 effectively protects the large pulley 7, the small pulley 8, and the belt 9, preventing debris from being drawn in and affecting transmission stability, and also avoiding accidental contact by personnel that could cause safety hazards. Example 2:

[0025] The difference between the above embodiments and this embodiment is that: Figures 1 to 9 As shown, a pair of collection trays 13 are located at the bottom of the frame 1, used to collect polishing fluid. A threaded rod 14 is screwed onto the side wall of the frame 1, and the end of the threaded rod 14 is rotatably connected to a baffle 15. A positioning rod 16 is installed on the baffle 15, and the positioning rod 16 movably passes through the side wall of the frame 1. The collection trays 13 can recover excess polishing fluid during the polishing process, reducing resource waste and environmental pollution. The cooperation between the threaded rod 14 and the positioning rod 16 allows for flexible adjustment of the position of the baffle 15, ensuring that the baffle 15 tightly fits the edge of the cathode roller 2, improving the accuracy and reliability of edge protection, and preventing the baffle 15 from shifting and affecting the protective effect.

[0026] like Figures 1 to 9 As shown, in a specific embodiment, a sliding groove 18 is provided inside the base 17, and a lead screw shaft 19 is rotatably mounted on the sliding groove 18. A shift motor 21 is installed on the side wall of the frame 1, and the output end of the shift motor 21 is connected to the lead screw shaft 19. A slide seat 22 is meshed on the outer side wall of the lead screw shaft 19, and the slide seat 22 is slidably connected to the sliding groove 18. A bellows cover 20 is installed at the end of the slide seat 22 and the sliding groove 18, and the bellows cover 20 covers the sliding groove 18. A hydraulic push rod 23 is installed on the slide seat 22, and the output end of the hydraulic push rod 23 is connected to the bottom of the bracket 24. Through the cooperation of the shift motor 21, lead screw 19, and slide 22, the polishing roller 27 moves smoothly along the surface of the cathode roller 2, ensuring full polishing coverage. The hydraulic push rod 23 can flexibly adjust the fit between the polishing roller 27 and the cathode roller 2 to adapt to different polishing needs. The bellows cover 20 can prevent polishing liquid and debris from entering the slide groove 18, ensuring the smooth sliding of the slide 22 and extending the service life of the shifting assembly.

[0027] like Figures 1 to 9As shown, a polishing motor 25 is further mounted on one end of the bracket 24, and a rotating shaft 26 is mounted on the output end of the polishing motor 25. The rotating shaft 26 is movably connected to the bracket 24, and the output end of the rotating shaft 26 is connected to the rotation center of the polishing roller 27. A controller 12 is also mounted on the side wall of the frame 1. The controller 12 is used to control the start and stop of the drive assembly, the shifting assembly, the hydraulic push rod 23, and the polishing motor 25. The polishing motor 25 and the rotating shaft 26 provide stable power to the polishing roller 27, ensuring that the polishing roller 27 rotates smoothly. The controller 12 can realize centralized control of various components of the equipment, improve the ease of operation of the equipment, facilitate precise control of the polishing process, and ensure the stability of polishing quality. Example 3:

[0028] The difference between the above embodiments and this embodiment is that: Figures 1 to 9 As shown, a water inlet pipe 41 is installed at the bottom of the flow divider 40, which is connected to the polishing fluid delivery system. A connecting cavity 45 is opened at the bottom of the flow divider plug 43, and the connecting cavity 45 is always connected to the water inlet pipe 41 and the flow divider cavity 46. The flow divider 40 is connected to the end of the air shroud 28. The continuous connection between the water inlet pipe 41 and the connecting cavity 45 ensures that the polishing fluid can be stably delivered into the flow divider 40. The matching cooperation between the flow divider cavity 46 and the gooseneck tube 42 provides structural protection for the direction switching of the polishing fluid. The connection between the flow divider 40 and the air shroud 28 ensures the stability of the linkage between the piston 36 and the flow divider plug 43, ensuring the coordinated operation of the overall structure.

[0029] like Figures 1 to 9 As shown, in a specific embodiment, a guide block 29 is installed at the end of the shroud 28, and a guide rail 30 is provided at the end of the polishing roller 27. The guide block 29 is slidably connected to the guide rail 30. A first air vent 33 is provided at one end of the shroud 28, and a second air vent 34 is provided at the other end. The fan blade 32 is located between the first air vent 33 and the second air vent 34, and the first air vent 33 and the second air vent 34 are located on both sides of the narrow channel 35. A connecting shaft 31 is installed at the rotation center of the fan blade 32, and the connecting shaft 31 is connected to the rotation center of the polishing roller 27. The cooperation between the guide block 29 and the guide rail 30 can ensure the stability of the shroud 28 when the polishing roller 27 rotates, and prevent the shroud 28 from deviating and affecting the airflow driving effect. The setting of the first air vent 33 and the second air vent 34 ensures that the air pressure inside the shroud 28 can be effectively changed when the fan blade 32 rotates. The connecting shaft 31 realizes the synchronous rotation of the polishing roller 27 and the fan blade 32, providing a power basis for the airflow pressure to drive the piston 36 to move.

[0030] like Figures 1 to 9As shown, further, a limiting plate 38 is installed at the end of the limiting rod 37. The diameter of the limiting plate 38 is larger than the diameter of the limiting rod 37. A limiting spring 39 is sleeved on the outer wall of the limiting rod 37. One end of the limiting spring 39 is engaged with the side wall of the limiting plate 38, and the other end of the limiting spring 39 is engaged with the side wall of the piston 36. The limiting spring 39 is used to limit the initial position of the piston 36. The limiting rod 37 and the limiting plate 38 can prevent the piston 36 from coming out of the narrow channel 35, avoiding failure of the linkage structure. The limiting spring 39 can accurately limit the initial position of the piston 36, ensuring that after the rotation direction of the polishing roller 27 is switched, the piston 36 and the diverter plug 43 can be smoothly reset, ensuring the reliability of the polishing fluid direction switching and improving the stability of the equipment's cyclic operation.

[0031] The implementation principle of a cathode roller polishing device with cathode roller edge protection according to the present invention is as follows: First, the main shaft on one side of the cathode roller 2 is rotatably connected to the bearing seat 3 at one end of the frame 1. The end of the main shaft on the other side is connected to the fixed plate 4 at the end of the synchronous shaft 5 on the fixed seat 6 at the other end of the frame 1 through the connecting flange, so as to ensure that the cathode roller 2 can rotate stably under the support of the bearing seat 3 and the fixed seat 6, laying the foundation for subsequent polishing operations.

[0032] After the cathode roller 2 is installed, the position of the baffle 15 is adjusted by the threaded rod 14 on the side wall of the frame 1. The threaded rod 14 is rotated to drive the baffle 15 to move along the guide direction of the positioning rod 16 until the baffle 15 is tightly attached to the edge of the cathode roller 2, thereby protecting the edge of the cathode roller 2 and preventing polishing liquid from splashing onto the edge or causing wear and scratches during the polishing process. The positioning rod 16 can ensure the stability of the baffle 15 during the movement process and prevent it from shifting and affecting the protective effect.

[0033] Subsequently, the drive assembly is started by the controller 12. The drive motor 10 in the drive assembly works, driving the small pulley 8 at the output end to rotate. The small pulley 8 drives the large pulley 7 at the end of the synchronous shaft 5 to rotate synchronously through the belt 9. The synchronous shaft 5 drives the cathode roller 2 to rotate stably through the fixed disk 4. The protective cover 11 can protect the large pulley 7, the small pulley 8 and the belt 9 to avoid the safety hazards of foreign objects being caught or personnel accidentally touching them during the transmission process.

[0034] After the cathode roller 2 starts rotating, the controller 12 controls the shifting assembly and the polishing motor 25 to work. The shifting motor 21 in the base 17 of the shifting assembly drives the lead screw 19 to rotate in the slide groove 18. The lead screw 19 drives the meshing slide block 22 to slide along the slide groove 18. The hydraulic push rod 23 on the slide block 22 can adjust the height of the bracket 24, thereby adjusting the fit between the polishing roller 27 on the bracket 24 and the surface of the cathode roller 2, ensuring the polishing effect. The bellows cover 20 covers the slide groove 18 to prevent polishing liquid or debris from entering the slide groove 18 and affecting the smooth sliding of the slide block 22. When the polishing motor 25 is working, it drives the polishing roller 27 to rotate through the rotating shaft 26. The rotating polishing roller 27 contacts the surface of the rotating cathode roller 2, realizing the polishing treatment of the surface of the cathode roller 2.

[0035] During the polishing process, the polishing fluid delivery system delivers polishing fluid into the inner cavity of the distributor 40 through the water inlet pipe 41 at the bottom of the distributor 40. The water inlet pipe 41 is always connected to the connecting cavity 45 at the bottom of the distributor plug 43, providing a basis for the stable delivery of polishing fluid.

[0036] When the polishing roller 27 rotates clockwise, its rotation center drives the fan blade 32 to rotate clockwise synchronously inside the air cover 28 through the connecting shaft 31. At this time, the fan blade 32 will discharge the gas inside the air cover 28 to the outside, so that a negative pressure state is formed inside the air cover 28. The suction force generated by the negative pressure will drive the piston 36 on the narrow channel 35 to move outward from the narrow channel 35. Finally, the first air outlet 33 and the second air outlet 34 on the air cover 28 are connected to each other, realizing smooth airflow. At the same time, the movement of the piston 36 will synchronously drive the flow divider 43 connected to it to slide inside the flow divider 40, so that the flow divider cavity 46 on the flow divider 43 is precisely connected to one of the gooseneck tubes 42, so that the gooseneck tube 42 is in working state. At this time, the polishing liquid is delivered from the gooseneck tube 42 to the polishing position through the connecting cavity 45 and the flow divider cavity 46, and the direction of the water flow is consistent with the clockwise rotation direction of the polishing roller 27, ensuring that the polishing liquid can closely adhere to the surface of the polishing roller 27 and fully cover the polishing area.

[0037] When the polishing roller 27 rotates counterclockwise, the connecting shaft 31 drives the fan blade 32 to rotate counterclockwise synchronously. At this time, the fan blade 32 no longer discharges gas outward, but instead draws external gas into the wind shroud 28, causing the internal pressure of the wind shroud 28 to increase. The increased air pressure will push the piston 36 to move in the opposite direction into the narrow channel 35 until it returns to the initial position. At the same time, the piston 36 drives the diverter plug 43 to slide in the opposite direction, so that the diverter chamber 46 connects with another gooseneck tube 42 and switches to work on the gooseneck tube 42. At this time, the water flow direction also changes accordingly and is consistent with the counterclockwise rotation direction of the polishing roller 27.

[0038] The smooth switching between the two rotation directions of the polishing roller 27, combined with the synchronous switching of the gooseneck tube 42 and the adaptation of the water flow direction, can effectively avoid problems such as polishing liquid splashing and uneven coverage that occur when the polishing liquid and the polishing roller 27 rotate in opposite directions. This ensures that the polishing liquid can always uniformly cover the polishing surface during the polishing process, which not only improves the uniformity and quality of polishing but also reduces the waste of polishing liquid. At the same time, the water flow direction is consistent with the rotation direction of the polishing roller, which can also help to remove the debris generated during the polishing process, preventing debris residue from affecting the polishing effect, further protecting the surface accuracy of the polishing roller 27 and the cathode roller 2, and extending the service life of the equipment components.

[0039] During the aforementioned movement, the guide block 29 at the end of the fan shroud 28 is slidably connected to the guide rail 30 at the end of the polishing roller 27, ensuring the stability of the fan shroud 28 during the rotation of the polishing roller 27 and preventing it from shifting and affecting the airflow driving effect. The limiting spring 39 is used to limit the initial position of the piston 36, ensuring that the piston 36 and the diverter plug 43 can reset when the polishing roller 27 returns to its initial rotation direction, ensuring the stable operation of the equipment. Excess polishing liquid generated during the polishing process will fall into a pair of collection trays 13 at the bottom of the frame 1 for subsequent recycling and treatment, reducing resource waste and environmental pollution.
