Description

Technical Field

[0001] This invention belongs to the technical field of cathode plate leveling equipment, and particularly relates to a cathode plate vertical leveling machine and control method. Background Technology

[0002] During operation, the cathode plate in a nickel sulfate electrolytic cell releases electrons, causing a reduction reaction of nickel ions in the electrolyte, resulting in the deposition of metallic nickel on the cathode plate. Initially, the cathode plate is cut from a nickel plate approximately 0.3mm thick and suspended in the electrolyte tank using copper tubing and slings. Once the cathode plate reaches a thickness of about 10mm, it meets the finished product requirements, and after removing the copper tubing, it can be sold to steel mills. In production practice, it has been found that bending deformation is particularly severe and irregular, especially as the cathode plate thickness increases from 0.3mm to 3mm. Current leveling methods involve workers lifting the cathode plate and hammering it flat, which is not only labor-intensive and inefficient but also produces unsatisfactory leveling results and easily leaves hammer marks. Summary of the Invention

[0003] The purpose of this invention is to provide a cathode plate vertical leveling machine and control method to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the specific technical solution of the cathode plate vertical leveling machine and control method of the present invention is as follows:

[0005] A cathode plate vertical leveling machine includes a frame, a leveling assembly, a tensioning assembly, a lifting assembly, and an air supply assembly. The frame includes a base and a square bracket. The square bracket is vertically fixed to the base, and the cathode plate is suspended from the upper end of the square bracket. The two ends of the leveling assembly are fixed to the vertical bars on both sides of the square bracket, allowing it to move up and down along the vertical bars to clamp and level the cathode plate. The tensioning assembly is fixed to a crossbeam below the square bracket to tension the bottom of the cathode plate. The lifting assembly is fixed to both ends above the square bracket to support and lift the cathode plate. The air supply assembly is fixed to one side of the base to supply air to the leveling assembly, tensioning assembly, and lifting assembly, driving each assembly to work.

[0006] Furthermore, the leveling assembly includes a linear guide pair, a driving device, a leveling device, a clamping device, and a sensor. The linear guide pair is fixedly installed on the vertical bars on both sides of the square bracket to provide linear motion guidance for the leveling device. The driving device is used to drive the leveling device to move up and down. The leveling device is used to clamp the surface of the cathode plate during the up and down movement. The clamping device is used to make the leveling device fit tightly against the cathode plate to achieve clamping and leveling.

[0007] Furthermore, the leveling device includes two mounting seats, an active roller and a driven roller. The two mounting seats are slidably connected to the linear guide rail pairs on both sides of the square bracket via sliders. The active roller and the driven roller are installed between the mounting seats on both sides. The active roller and the driven roller include upper and lower sets. The cathode plate is placed between the active roller and the driven roller. Leveling is achieved by clamping the active roller and the driven roller and moving them up and down.

[0008] Furthermore, the driving device includes a drive motor, a bidirectional drive linkage, a drive sprocket, a driven sprocket, a chain, a rack, and a lifting gear. The driven sprocket and the lifting gear are coaxially fixedly installed at both ends of the two drive rollers, and the two driven sprockets on the same side mesh with each other. The output end of the drive motor is connected to the bidirectional drive linkage, and both ends of the bidirectional drive linkage are fixedly connected to the drive sprocket. The drive sprocket and the driven sprocket are connected by chain transmission. The drive motor drives the bidirectional drive linkage to rotate, which in turn drives the drive sprocket to rotate, thereby driving the drive rollers to rotate. The rack is fixedly installed on the inner side of the vertical rods on both sides of the square bracket. The lifting gear meshes with the rack and moves up and down along the rack under the drive of the driving device to realize the up and down movement of the leveling device.

[0009] Furthermore, the clamping device is fixedly installed on the mounting bases on both sides, including a clamping cylinder and a driven sprocket fixing base. The mounting base has an adjustment groove. The axle of the driven roller passes through the adjustment groove and is rotatably and fixedly connected to the driven sprocket fixing base through a bearing. The clamping cylinder is fixedly installed on the mounting base, and its output end is fixedly connected to the driven sprocket fixing base. Driven by the clamping cylinder, the driven roller can move closer to and further away from the driving sprocket along the adjustment groove to clamp the cathode plate. During the up-and-down movement of the leveling device, it rotates synchronously or moves away from the cathode plate to clamp or release the cathode plate. During the clamping process, it rotates synchronously with the up-and-down movement of the leveling device.

[0010] Furthermore, the sensor includes an upper limit limit switch and a lower limit limit switch. The upper limit limit switch is fixedly installed on the upper end of the vertical rod on one side of the square bracket, and the lower limit limit switch is fixedly installed on the lower end of the vertical rod on one side of the square bracket. The upper limit limit switch is used to detect the upper limit of the leveling device's movement, and the lower limit limit switch is used to detect the lower limit of the leveling device's movement.

[0011] Furthermore, the tensioning assembly includes a tensioning cylinder, a pull plate, a clamping plate, a clamping block, and a stop bar. The tensioning cylinder is fixedly installed on the crossbeam below the square bracket. The output end of the tensioning cylinder is connected to the pull plate. A clamping plate is fixed to the front end of the pull plate. A clamping block is fixed to the inner side of the clamping plate. The stop bar is fixedly installed on one side of the lower end of the cathode plate. The position of the clamping block is opposite to the stop bar and is set on the other side of the lower end of the cathode plate. When the tensioning cylinder extends or retracts, it causes the pull plate to retract. The clamping block moves closer to the stop bar, thereby clamping the lower end of the cathode plate and preventing the cathode plate from moving upward with the leveling device.

[0012] Furthermore, the lifting assembly includes a lifting cylinder and a copper tube clamping block. The two lifting cylinders are respectively fixed at both ends above the square bracket. The bottom of the copper tube clamping block is fixedly connected to the output end of the lifting cylinder. The lifting cylinder can drive the copper tube clamping block to rise or fall. The cathode plate is suspended on the copper tube by two straps. The copper tube clamping block is welded from V-shaped groove blocks and channel steel. When assembling the cathode plate, both ends of the copper tube rest in the V-shaped groove blocks.

[0013] Furthermore, the air source assembly is fixedly installed on the base and includes a control device and an air supply device. The air supply device is connected to the cylinders of the leveling assembly, the tensioning assembly, and the lifting assembly, and supplies air to each assembly under the control of the control device.

[0014] This invention also discloses a control method for a cathode plate vertical leveling machine, comprising the following steps:

[0015] Step 1: Initialization phase: When the equipment is started, the leveling component automatically descends to the lower limit, the lifting component falls, and the clamping device and tensioning component are both in the loosened state;

[0016] Step 2: Cathode plate loading: The cathode plate is manually suspended on the lifting assembly;

[0017] Step 3: Clamping and Leveling Preparation: The tensioning assembly clamps the bottom of the cathode plate; the clamping device is activated to clamp the surface of the cathode plate;

[0018] Step 4: First bottom-up leveling: The leveling assembly moves from bottom to top, clamps the cathode plate and rolls it to eliminate bending deformation; when the leveling assembly rises to the upper limit, it stops and the clamping device and tensioning assembly are released.

[0019] Step 5: Adjust the position of the cathode plate: The lifting assembly moves to raise the cathode plate a certain distance, ensuring that the leveling area covers the bottom area; the clamping device works to clamp the cathode plate again;

[0020] Step 6: Second top-to-bottom leveling: The control device controls the leveling assembly to move from top to bottom to perform a second leveling of the cathode plate; when the leveling assembly moves to the lower limit, it stops, the clamping device and the tensioning assembly are released, and the lifting assembly falls down to reset.

[0021] Step 7: Unload the cathode plate: Manually remove the leveled cathode plate to prepare for the next round of operations.

[0022] The cathode plate vertical leveling machine and control method of the present invention have the following advantages:

[0023] High-efficiency automated leveling: The cathode plate is clamped by the cooperation of the active and driven rollers of the leveling component and moves up and down along the linear guide rail to achieve automated leveling, which significantly improves leveling efficiency and reduces manual intervention and labor intensity.

[0024] Precise leveling control: The clamping device and sensors (such as upper and lower limit switches) are used to ensure precise control of the clamping force and movement range of the cathode plate during the leveling process, so that the parallelism of the cathode plate after leveling can be controlled within ±2mm, thereby improving the leveling quality.

[0025] To prevent cathode plate displacement: The tensioning assembly uses a cylinder to drive the clamping block and the stop bar to clamp the bottom of the cathode plate, effectively preventing the cathode plate from moving upward due to friction during the leveling process.

[0026] Full coverage of the leveling range: The lifting component adjusts the height of the cathode plate through a cylinder, and in conjunction with the up and down movement of the leveling component, ensures that the leveling covers the entire length, avoiding the problem of traditional tensioning mechanisms occupying the leveling area.

[0027] Compact structure and easy to move: The frame base is equipped with casters, and the square bracket has lifting rings, which facilitates the movement and hoisting of the equipment, adapts to the needs of different work sites, and improves the flexibility of use.

[0028] Synchronous drive and stable operation: The drive unit adopts a two-way drive linkage, sprocket and rack transmission to ensure synchronous rotation of the two rollers and smooth up and down movement of the leveling device, avoiding the cathode plate being dragged or deformed due to speed difference.

[0029] Reduce the risk of manual operation: By centrally controlling the action of each cylinder through the air source component, the leveling, clamping and lifting processes are automated, avoiding manual operation and improving the safety and efficiency of the operation.

[0030] In summary, this invention solves the problems of low efficiency and poor results of traditional manual leveling through automated mechanisms and precise control, while taking into account the flexibility, stability and environmental friendliness of the equipment, making it suitable for the needs of continuous industrial production.

Detailed Implementation

[0040] To better understand the purpose, structure, and function of this invention, the following detailed description of a cathode plate vertical leveling machine is provided in conjunction with the accompanying drawings.

[0041] like Figure 1-8As shown, a cathode plate vertical leveling machine of the present invention includes a frame 1, a leveling assembly 2, a tensioning assembly 3, a lifting assembly 4, a drainage assembly 5, and an air supply assembly 6. The frame 1 includes a base 11 and a square bracket 12. The square bracket 12 is vertically fixed to the base 11, and the cathode plate 7 is suspended from the upper end of the square bracket 12. The leveling assembly 2 is fixed at both ends to vertical rods 121 on both sides of the square bracket 12, and can move up and down along the vertical rods to clamp and level the cathode plate 7. The tensioning assembly 3 is fixed to the crossbeam below the square bracket 12 and is used to tension the bottom of the cathode plate 7 to prevent the cathode plate 7 from being pulled up by friction during upward leveling. The lifting assembly 4 is fixed at both ends above the square bracket 12 and is used to support and lift the cathode plate 7. The drainage assembly 5 is located on the base 11 and is used to drain the acid attached to the cathode plate 7. The air supply assembly 6 is fixed to one side of the base 11 and is used to supply air to the leveling assembly 2, the tensioning assembly 3, and the lifting assembly 4 to drive each assembly.

[0042] like Figure 3 Figure 4 As shown, the leveling assembly 2 includes a linear guide pair 21, a drive device 22, a leveling device 23, a clamping device 24, and a sensor 25. The linear guide pair 21 is fixedly mounted on the vertical rods 121 on both sides of the square bracket 12, providing linear motion guidance for the leveling device 23. The drive device 22 is used to drive the leveling device 23 to move up and down. The leveling device 23 is used to clamp the surface of the cathode plate 7 during the up and down movement. The clamping device is used to make the leveling device 23 fit tightly against the cathode plate 7, achieving clamping and leveling.

[0043] The leveling device 23 includes two mounting seats 231, an active roller 232, and a driven roller 233. The two mounting seats 231 are slidably connected to the linear guide rail pairs 21 on both sides of the square bracket 12 via sliders. The active roller 232 and the driven roller 233 are installed between the mounting seats 231 on both sides. The active roller 232 and the driven roller 233 include upper and lower sets. The cathode plate 7 is placed between the active roller 232 and the driven roller 233. Leveling is achieved by clamping the active roller 232 and the driven roller 233 and moving them up and down.

[0044] The drive unit 22 includes a drive motor 221, a bidirectional drive linkage 222, a drive sprocket 223, an idler gear 224, a driven sprocket 225, a chain 226, a rack 227, and a lifting gear 228. The driven sprocket 225 and the lifting gear 228 are coaxially fixedly installed at both ends of the two drive rollers 232. The two driven sprockets 225 on the same side mesh with each other. The output end of the drive motor 221 is connected to the bidirectional drive linkage 222. Both ends of the bidirectional drive linkage 222 are fixedly connected to the drive sprocket 223. The drive sprocket 223 and the driven sprocket 225 are connected by a chain 226. The drive motor 221 drives the bidirectional drive linkage 222 to rotate, which in turn drives the drive sprocket 223 to rotate. The drive sprocket 223 drives the driven sprocket 225 to rotate, thereby driving the drive rollers 232 to rotate. The rack 227 is fixedly installed on the inner side of the vertical rods 121 on both sides of the square bracket 12. The lifting gear 228 meshes with the rack 227 and moves up and down along the rack 227 under the drive of the drive device 22 to realize the up and down movement of the leveling device 23.

[0045] Since the positions of the drive sprocket 223 and the two driven sprockets 225 are fixed, an idler gear 224 is provided near the chain 226 for tensioning to ensure tight engagement of the three sprockets. The idler gear 224 is fixedly mounted on the mounting base 231 and abuts against the chain 226.

[0046] like Figure 5 As shown, the clamping device 24 is fixedly mounted on the mounting bases 231 on both sides, including a clamping cylinder 241 and a driven sprocket fixing base 242. The mounting base 231 has an adjustment groove 2311. The axle of the driven roller 233 passes through the adjustment groove 2311 and is rotatably and fixedly connected to the driven sprocket fixing base 242. The clamping cylinder 241 is fixedly mounted on the mounting base 231, and its output end is rotatably and fixedly connected to the driven sprocket fixing base 242 through a bearing. Driven by the clamping cylinder 241, the driven roller 233 can move closer to and further away from the driving sprocket 223 along the adjustment groove 2311, thereby clamping or releasing the cathode plate 7. During the clamping process, it rotates synchronously with the leveling device 23 as it moves up and down. By adjusting the force of the clamping cylinder 241, the parallelism of the leveled cathode plate 7 can be controlled within ±2mm.

[0047] During assembly, first install the driven roller 233, insert the pins into the shaft holes of the mounting base 231 from both sides, then secure them with the limit block 234, then install the clamping device 24, and then install the driving roller 232. Since the outer diameter of the driving roller 232 is 2mm smaller than the outer diameter of the bearing on one side, it can be directly inserted from the side of the mounting base 231. Finally, connect the chain 226 and install the idler wheel 224. The key is to ensure that the outer diameters of the driving roller 232 and the driven roller 233 are equal to the pitch circle diameter of the lifting gear 228, thereby avoiding the drag force on the cathode plate 7 caused by the speed difference.

[0048] like Figure 2As shown, the sensor 25 includes an upper limit limit switch 251 and a lower limit limit switch 252. The upper limit limit switch 251 is fixedly installed on the upper end of the vertical rod 121 on one side of the square bracket 12, and the lower limit limit switch 252 is fixedly installed on the lower end of the vertical rod 121 on one side of the square bracket 12. The upper limit limit switch 251 is used to detect the upper limit of the movement of the leveling device 23, and the lower limit limit switch 252 is used to detect the lower limit of the movement of the leveling device 23.

[0049] like Figure 6 As shown, the tensioning assembly 3 includes a tensioning cylinder 31, a pull plate 32, a clamping plate 33, a clamping block 34, and a stop bar 35. The tensioning cylinder 31 is fixedly installed on the crossbeam below the square bracket 12. The output end of the tensioning cylinder 31 is connected to the pull plate 32. The clamping plate 33 is fixed to the front end of the pull plate, and the clamping block 34 is fixed to the inner side of the clamping plate 33. The stop bar 35 is fixedly installed on one side of the lower end of the cathode plate 7, and the position of the clamping block 34 is opposite to the stop bar 35, located on the other side of the lower end of the cathode plate 7. When clamping is required, the tensioning cylinder 31 extends and retracts, causing the pull plate 32 to retract, and the clamping block 34 approaches the stop bar 35, thereby clamping the lower end of the cathode plate 7 and preventing the cathode plate 7 from moving upward with the leveling device 23. Preferably, the clamping block 34 is made of fluororubber, which can increase friction.

[0050] like Figure 7 As shown, the lifting assembly 4 includes a lifting cylinder 41 and a copper pipe clamping block 42. The two lifting cylinders 41 are fixed at both ends above the square bracket 12. The bottom of the copper pipe clamping block 42 is fixedly connected to the output end of the lifting cylinder 41. The lifting cylinder 41 can drive the copper pipe clamping block 42 to rise or fall. The cathode plate 7 is suspended from the copper pipe 72 by two slings 71. The copper pipe clamping block 42 is welded from V-shaped groove blocks and channel steel. When assembling the cathode plate 7, both ends of the copper pipe 72 rest within the V-shaped groove blocks.

[0051] like Figure 8 As shown, the drainage assembly 5 includes a water tank 51 and a drain valve 52. The water tank 51 is fixed on the base 11, and the drain valve 52 is connected to the bottom of the water tank. The acid liquid attached to the cathode plate 7 drips into the water tank 51. When drainage is required, the drain valve 52 is opened to drain the water.

[0052] The air source component 6 is fixedly installed on the base 11 and includes a control device and an air supply device. The air supply device is connected to the cylinders of the leveling component 2, the tensioning component 3, and the lifting component 4, and supplies air to each component under the control of the control device.

[0053] The base 11 is equipped with casters 111 for easy movement of the equipment, and the square bracket 12 is equipped with lifting rings 122, which can be used with lifting devices to transport the equipment to a designated location, making it flexible and convenient.

[0054] A control method for a cathode plate vertical leveling machine according to the present invention includes the following steps:

[0055] Step 1: Initialization phase: When the equipment is started, the leveling component 2 automatically descends to the lower limit position, the lower limit limit switch 252 is triggered, the lifting component 4 falls, and the clamping device 24 and the tensioning component 3 are both in the loosened state.

[0056] Step 2: Cathode plate loading: The cathode plate 7 is manually suspended from the copper pipe 72 on the copper pipe clamping block 42 of the lifting assembly 4, ensuring that both ends of the copper pipe are firmly placed in the V-shaped groove.

[0057] Step 3: Clamping and Leveling Preparation:

[0058] Clamping the bottom: The control device controls the tensioning cylinder 31 of the tensioning assembly 3 to close, and the clamping block 34 and the stop bar 35 cooperate to clamp the bottom of the cathode plate 7 to prevent displacement during calibration.

[0059] Clamping roller: When the clamping cylinder 241 of the clamping device 24 is closed, the driven roller 233 approaches the driving roller 232 and clamps the surface of the cathode plate 7.

[0060] Step 4: First leveling from bottom to top:

[0061] Drive motor start: The control device controls the drive motor 221 of the leveling component 2 to rotate forward, which drives the active roller 232 to rotate through the bidirectional drive linkage 222 and the sprocket system. At the same time, the lifting gear 228 moves upward along the rack 227, realizing the upward movement of the leveling component 2.

[0062] Leveling process: The driving roller 232 and the driven roller 233 clamp the cathode plate 7 and roll it to eliminate bending deformation.

[0063] Upper limit stop: When the leveling component 2 rises to the upper limit position and triggers the upper limit limit switch 251, the drive motor 221 stops, and the clamping device 24 and the tensioning component 3 are released;

[0064] Step 5: Adjust the position of the cathode plate:

[0065] Lifting operation: The lifting cylinder 41 of the lifting component 4 is activated to lift the cathode plate 7 upward by a distance such as 100mm, ensuring that the leveling range covers the bottom area.

[0066] Re-clamping: The clamping cylinder 241 of the clamping device 24 closes, clamping the cathode plate 7 again.

[0067] Step 6: Second leveling from top to bottom:

[0068] Reverse rotation of drive motor: The control device controls the drive motor 221 of the leveling component 2 to reverse, and the leveling component 2 moves from top to bottom to perform secondary leveling of the cathode plate 7.

[0069] Lower limit stop: When the leveling component 2 moves to the lower limit and triggers the lower limit travel switch 252, the drive motor 221 stops, the clamping cylinder 241 opens, and the lifting cylinder 41 falls to reset.

[0070] Step 7: Unload the cathode plate: Manually remove the leveled cathode plate 7 to prepare for the next round of operations.

[0071] Step 8: Drainage operation: The acid dripping during the leveling process is collected by the drainage component 5 and drained by opening the drain valve 52 periodically.

[0072] It is understood that the present invention has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. Furthermore, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention.
