Description

Technical Field

[0001] This utility model relates to the field of electrocatalysis technology, specifically to a leveling device for preparing metal plates for catalytic electrodes. Background Technology

[0002] The metal plate roller leveling device used for preparing catalytic electrodes is a specialized leveling equipment adapted to thin plates such as titanium and stainless steel. It adopts a multi-set precision roller graded pressure adjustment structure, combined with a servo drive system to precisely control the roller gap, which can eliminate rolling stress of the plate, correct warping deformation, and control the flatness error within 0.05mm / m. The equipment also has the functions of feeding guidance and discharging positioning, adapting to plates of different thicknesses, ensuring the flatness of the electrode substrate, laying the foundation for uniform coating in the subsequent process, and is a key auxiliary equipment for the mass production of catalytic electrodes.

[0003] For example, the utility model patent with announcement number CN216679631U discloses a leveling device for preparing metal plates for catalytic electrodes. It consists of a base frame, a base, a coupling, a transmission gear, a fixed side pressure roller group, a movable side pressure roller group, a positioning pin, a reducer, and a motor. The base frame is located below the device, and the base is fixed on the base frame. The motor, the fixed side pressure roller group, and the movable side pressure roller group are installed on the base from left to right. The reducer is connected to the motor via a belt, and a coupling is installed inside the reducer. The coupling is connected to the transmission gear. The fixed side plate with guide groove is fixed on the base, and the fixed side pressure roller group is set on the fixed side plate with guide groove. The connecting rod on one side of the fixed side lower pressure roller is connected to the coupling.

[0004] However, this leveling device has the following shortcomings:

[0005] It lacks an automatic flatness detection function, and after leveling, other processes are required to judge whether the board is qualified, which is inefficient and prone to misjudgment.

[0006] The lack of an integrated conveying system means that the loading and unloading of sheet materials relies on manual handling, which makes continuous operation impossible and results in low batch processing efficiency.

[0007] Without a cyclical leveling mechanism, substandard boards need to be manually reloaded, which is cumbersome and affects processing efficiency. Utility Model Content

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] Please see Figures 1-4 A leveling device for preparing a metal plate for a catalytic electrode, comprising:

[0032] Leveling bin 1, with a roller leveling machine 2 detachably installed inside leveling bin 1;

[0033] The conveying assembly is divided into a feeding conveyor belt 3 and a discharging conveyor belt 4. The feeding conveyor belt 3 and the discharging conveyor belt 4 are respectively installed at the inlet and outlet of the roller leveling machine 2 and are slidably connected to the inner wall of the leveling bin 1.

[0034] The circulating conveyor belt 5 is located below the roller leveler 2 and is fixedly connected to the inner wall of the leveling bin 1;

[0035] The laser flatness detector 6 is set above the discharge port of the roller leveler 2 and is fixedly connected to the top wall of the leveling chamber 1.

[0036] In use, the leveling chamber 1 provides a closed working space for the roller leveler 2, conveying components, and other parts, reducing the impact of external impurities on the leveling quality of the sheet metal. The roller leveler 2 applies roller pressure to the metal sheet metal to correct warping and deformation, achieving leveling. The feeding conveyor belt 3 transports the metal sheet metal to be leveled to the feeding port of the roller leveler 2 for automatic feeding. The discharging conveyor belt 4 transports the leveled metal sheet metal out of the roller leveler 2, completing the unloading process. The circulating conveyor belt 5 receives the sheet metal that fails the laser flatness detector 6 and transports it back to the feeding end for re-leveling, improving the finished product qualification rate. The laser flatness detector 6 monitors the flatness of the leveled sheet metal in real time, determines whether the sheet metal meets the processing requirements, and provides feedback on the detection signal. When the laser flatness detector 6 detects that the sheet metal is uneven more than three times, it issues an alarm to remind the operator to replace or repair the roller leveler 2.

[0037] Please see Figure 1 The inner two side walls of the leveling bin 1 are provided with guide grooves 7, and the two side walls of the feeding conveyor belt 3 and the discharging conveyor belt 4 are fixedly installed with limiting blocks 8 that are slidably adapted to the guide grooves 7.

[0038] In use, the guide groove 7 provides sliding guidance for the limit block 8, regulating the movement trajectory of the feed conveyor belt 3 and the discharge conveyor belt 4; the limit block 8 is slidably adapted to the guide groove 7 to prevent the feed conveyor belt 3 and the discharge conveyor belt 4 from deviating during operation, ensuring accurate conveying of the sheet material.

[0039] Please see Figure 4 The two side walls of the leveling chamber 1 are fixedly equipped with support platforms 9, and the input transmission belt 10 and the output transmission belt 11 are fixedly installed on the two support platforms 9 respectively.

[0040] In use, the support platform 9 provides installation support for the input transmission belt 10 and the output transmission belt 11, ensuring stable operation of the transmission belts; the input transmission belt 10 connects the external feeding equipment and the feeding conveyor belt 3 to realize the transfer and conveying of the board to be leveled; the output transmission belt 11 connects the discharge conveyor belt 4 and the external receiving equipment to realize the transfer and collection of the leveled board.

[0041] Please see Figures 1-2 The input drive belt 10 and the output drive belt 11 correspond to the ports of the feed conveyor belt 3 and the discharge conveyor belt 4, respectively. Transition guide rollers 12 are fixedly installed at the ports of the input drive belt 10, the output drive belt 11 and the circulating conveyor belt 5.

[0042] During use, the transition guide roller 12 guides the sheet material to transition smoothly and prevents jamming.

[0043] Please see Figures 1-4 Both support platforms 9 have structural reinforcing ribs 13 fixedly installed on their outer walls. During use, the structural reinforcing ribs 13 enhance the structural strength and load-bearing capacity of the support platforms 9, prevent the support platforms 9 from deforming due to the weight of the transmission belt and plates, and ensure the long-term operational stability of the equipment.

[0044] Please see Figures 3-4 Four light bars 14 are installed below the circulating conveyor belt 5. Both ends of the four light bars 14 are fixedly connected to the inner side walls of the two support platforms 9. Two adjusting frames 15 are sleeved on the four light bars 14. A guide tilt angle 16 is opened above the two adjusting frames 15. A sliding sleeve 17 that is adapted to slide with the light bars 14 is fixedly installed inside the adjusting frame 15.

[0045] In use, the guide bar 14 provides a sliding guide for the adjusting frame 15, ensuring that the adjusting frame 15 moves smoothly and accurately; the adjusting frame 15 cooperates with the support frame 18 through the guide tilt angle 16 to adjust the height of the feeding conveyor belt 3 and the discharging conveyor belt 4, realizing the lifting and lowering adjustment of the input transmission belt 10 and the output transmission belt 11; the guide tilt angle 16 guides the support frame 18 to move with the adjusting frame 15, realizing the smooth adjustment of the conveyor belt height; the sliding sleeve 17 is slidably adapted to the guide bar 14, reducing the friction when the adjusting frame 15 moves and improving the adjustment flexibility.

[0046] Please see Figures 3-4 The lower walls of the feeding conveyor belt 3 and the discharging conveyor belt 4 are both fixedly equipped with support frames 18 that are slidably adapted to the guide inclination angle 16. The center of each of the two adjusting frames 15 is fixedly equipped with a screw sleeve 19. A double-acting screw 20 is screwed into the screw sleeve 19. The two ends of the double-acting screw 20 are connected to a motor transmission box 21 and an adapter sleeve 22.

[0047] In use, the support frame 18 connects the feed conveyor belt 3, the discharge conveyor belt 4, and the adjusting frame 15, transmitting the displacement of the adjusting frame 15 to achieve conveyor belt height adjustment; the screw sleeve 19 is threadedly engaged with the double-acting screw 20, converting the rotational motion of the double-acting screw 20 into the linear movement of the adjusting frame 15; the double-acting screw 20 drives the two adjusting frames 15 to move synchronously in opposite or the same direction through rotation, precisely adjusting the conveyor belt height; the motor transmission box 21 provides rotational power to the double-acting screw 20, controlling the moving speed and stroke of the adjusting frame 15; the adapter sleeve 22 achieves a stable connection between the double-acting screw 20 and the motor transmission box 21, ensuring smooth power transmission.

[0048] Example 1: In this example, the laser flatness detector 6, in conjunction with the feeding conveyor belt 3 and the discharging conveyor belt 4, achieves the detection of leveling defects. Defects are re-leveled via the circulating conveyor belt 5. If the number of times exceeds the set limit, an alarm is triggered to remind the operator to replace or repair the roller leveling machine 2.

[0049] Specifically, before leveling, the bidirectional lead screw 20 is driven to rotate by the motor transmission box 21, which drives the two adjusting frames 15 to move synchronously along the guide rod 14 (the sliding sleeve 17 reduces the friction of movement). The guide angle 16 of the adjusting frame 15 is slidably adapted to the support frame 18 on the lower wall of the feeding conveyor belt 3 and the discharging conveyor belt 4. The height of the conveyor belt is adjusted by the displacement of the adjusting frame 15, so that the feeding conveyor belt 3 is precisely connected with the input transmission belt 10 and the discharging conveyor belt 4 is precisely connected with the output transmission belt 11. The limiting blocks 8 on both sides of the conveyor belt slide along the guide groove 7 of the leveling bin 1 to ensure that the position does not deviate.

[0050] After the equipment is started, the metal sheet to be leveled is conveyed by the input conveyor belt 10, smoothly transitioned to the feed conveyor belt 3 via the transition guide roller 12, and then fed into the roller leveling machine 2 for roller pressing and leveling. The leveled sheet is conveyed to the inspection area by the discharge conveyor belt 4, where the laser flatness detector 6 on the top wall of the leveling bin 1 detects the flatness of the sheet in real time. If the inspection is qualified, the sheet passes through the transition guide roller 12 into the output conveyor belt 11 and is transferred to the subsequent process; if the inspection is unqualified, the sheet is guided to the circulating conveyor belt 5, and then returned to the feed conveyor belt 3 via the transition guide roller 12, and re-enters the roller leveling machine 2 for leveling.

[0051] Each cycle involves re-inspection by the laser flatness detector 6. If the same board material fails three consecutive inspections, the laser flatness detector 6 issues an alarm, reminding the operator to replace or repair the roller leveler 2 to prevent the continuous production of defective products. The entire process requires no manual screening, achieving a closed-loop operation of automatic inspection, cyclic leveling, and quality early warning.

[0052] Example 2: In this example, the feeding conveyor belt 3 and the discharging conveyor belt 4 are raised and lowered synchronously through bidirectional screw linkage adjustment and guide structure limiting, ensuring that they are always precisely aligned with the roller leveler 2 and the circulating conveyor belt 5, and avoiding material jamming or deviation during conveying.

[0053] Specifically, when the conveyor belt height needs to be adjusted, the laser planar detector 6 activates the motor transmission box 21, driving the bidirectional lead screw 20 to rotate. The bidirectional lead screw 20 engages with the threaded sleeve 19 at the center of the two adjusting frames 15, causing the two adjusting frames 15 to move synchronously and in the same direction along the four guide rods 14 (the sliding sleeve 17 slides and adapts to the guide rods 14 to ensure smooth movement). The guide angle 16 above the adjusting frame 15 is in close contact with the support frame 18 on the lower wall of the feeding conveyor belt 3 and the discharging conveyor belt 4. As the adjusting frame 15 moves, the guide angle 16 pushes the support frame 18 to rise and fall synchronously, thereby causing the feeding conveyor belt 3 and the discharging conveyor belt 4 to move up and down synchronously.

[0054] During movement, the limiting blocks 8 on both sides of the feeding conveyor belt 3 and the discharging conveyor belt 4 slide along the guide groove 7 on the inner wall of the leveling chamber 1, limiting the lateral displacement of the conveyor belts and ensuring accurate lifting trajectory. Through precise adjustment, the discharge end of the feeding conveyor belt 3 is aligned with the inlet of the roller leveler 2, and the feeding end of the discharging conveyor belt 4 is aligned with the outlet of the roller leveler 2. At the same time, the guide end of the unqualified board material on the discharging conveyor belt 4 is aligned with the feeding end of the circulating conveyor belt 5. The four optical bars 14 provide stable support for the adjustment frame 15, and together with the structural reinforcing ribs 13 on the outer wall of the support platform 9, prevent equipment deformation during adjustment, ensure alignment accuracy during long-term use, and ensure smooth connection of board material conveying.

[0055] 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.
