It consists of two or more coils wound on a shared magnetic iron core. The main winding is powered by an alternating current, which generates an alternating magnetic field, thereby inducing an electromotive force in the secondary winding. For this purpose, a Chinese patent discloses a current transformer iron core winding device, application number CN202323422768.1.

An anti-deviation retaining ring is fixedly sleeved on one side of the anti-deviation clamping roller. A mounting bracket is snapped onto one side of the top of the mounting base plate. An electric demolding rod is snapped onto one end of the mounting bracket. A translation slide is movably sleeved on the outside of the electric demolding rod. Limiting lugs are snapped onto both ends of the mounting bracket. One end of the electric demolding lever is rotatably connected to a rotating disk, and both ends of the rotating disk are engaged with anti-deviation cross frames.

[0011] According to the above technical solution, one end of the translational slide is embedded in the limiting lug, and the other two parallel pads are provided with grooves on opposite ends. One end of the inner support demolding claw is embedded in the groove, and one end of the inner support demolding claw is engaged with a rubber protrusion.

The signal input terminal of the infrared rangefinder is connected to the input terminal of the electric strut. The output shaft of the drive motor is connected to one end of the conveyor belt shaft.

[0013] According to the above technical solution, a method for winding the iron core of a current transformer includes the following steps: S1. Control the rotation of the internal thread vertical cylinder and the internal thread horizontal cylinder so that the two opposite width adjustment rods move synchronously in opposite directions, thereby pushing the side push plate and the corner support to move and adjust the size of the iron core winding. S2. Start the electric demolding lever to extend, pushing the rotating disk, anti-deviation cross frame and inner support demolding claw to move, so that they are embedded in the groove at one end of the parallel pad; S3. The lifting shaft seat is pushed by the support spring to slide along the inner wall of the clamping roller frame, and the conveying clamping roller is moved along with it. The distance between the two conveying clamping rollers is adjusted to clamp and fix silicon steel strips of different thicknesses. S4. Through the cooperation of the winding motor and transmission components, the winding frame and the conveying roller are driven to rotate to convey the silicon steel strip, and the silicon steel strip is attracted by the electromagnet to facilitate the rotation of the winding frame to wind the silicon steel strip. S5. The distance of the silicon steel strip conveyed is measured in real time using an infrared rangefinder. When the cumulative length reaches the preset core unfolding length, the electro-hydraulic rod is activated instantly to drive the shearing blade to cut down quickly and cut the silicon steel strip. S6. Start the electric support rod to extend. By opening the push block and rotating support plate, the two inner support demolding claws expand outward inside the formed iron core, and the inner wall is completely tightened, so that the electric demolding rod can drive the iron core to be pulled out smoothly and axially from the corner support. S7. The pulled-out iron core moves with the demolding mechanism and contacts the touch switch on the baffle plate, causing the electric support rod to retract and drive the inner support demolding claw to retract, so that the baffle plate can push the iron core out and onto the conveyor belt, and start the drive motor for conveying.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use. 1. A winding size adjustment mechanism is set up. Through the cooperation of support spring, lifting shaft seat and anti-deviation rod, it is convenient to move with the conveyor clamping roller. The distance between the two conveyor clamping rollers is adjusted to clamp and fix silicon steel strips of different thicknesses. The silicon steel strip is conveyed through the cooperation of winding motor, drive shaft, drive sprocket and drive chain. The silicon steel strip is attracted and fixed on the corner support frame by electromagnet, which facilitates the winding of silicon steel strip when the winding frame rotates. Furthermore, during the winding process, real-time distance measurement is performed using an infrared rangefinder, which facilitates timely control of the extension of the electro-hydraulic rod, pushing the shearing blade downward to cut the silicon steel strip, thus completing the winding of the iron core. This achieves automation of fixed-length cutting, improves production flexibility, and simultaneously stops the rotation of the winding motor and the attraction of the electromagnet, facilitating subsequent demolding. The internal threaded horizontal cylinder, the actuating gear, and the transmission gear ring work together to facilitate the rotation of the internal threaded horizontal cylinder and the internal threaded vertical cylinder. This pushes the internal width-adjusting top rod to move in the opposite direction, which in turn moves the side push plate, the parallel pad plate, and the corner support frame. This changes the width and length between the four corner support frames, adjusts the size of the iron core winding, and improves adaptability.

[0015] 2. An automatic demolding and limiting mechanism is set up. The tension spring pushes the clamping adjustment plate, concave plate and anti-deviation clamping roller to descend and clamp the silicon steel strip to ensure the tension of the winding. The anti-deviation retaining ring and the inner support demolding claw limit the winding silicon steel strip to prevent deviation and ensure the winding effect of the iron core. At the same time, during the winding, the inner support demolding claw, the anti-deviation cross frame and the rotating disk rotate, and the inner support demolding claw is wound on the inside of the iron core, which facilitates the subsequent support demolding. During demolding, the electric support rod pushes the push block to move, and with the cooperation of the rotating support plate, the two inner support demolding claws move synchronously in opposite directions, so that the telescopic connecting rod extends, increasing the distance between the two inner support demolding claws, supporting the wound iron core, so that when the electric demolding pull rod retracts later, it moves with the rotating disk, the anti-deviation cross frame and the inner support demolding claws to pull the wound iron core out from the corner support frame; When the iron core contacts the touch switch, the electric support rod retracts and resets, releasing the support on the iron core. This allows the iron core, supported on the inner support demolding claw, to be pushed out by the material stop push plate and fall onto the conveyor belt. The iron core is then transported onto the conveyor belt by the drive motor and the conveyor belt, improving the demolding efficiency.

[0016] In summary, by combining the winding size adjustment mechanism and the automatic demolding and limiting mechanism, a highly automated and adaptable transformer core winding equipment is constructed. This integrates winding, length setting, and demolding, reducing manual operation, ensuring processing continuity, and improving production efficiency. Furthermore, the winding size of the core can be freely adjusted as needed, greatly enhancing the equipment's versatility and meeting different production requirements. Attached Figure Description

The output shaft of the drive motor 422 is connected to one end of the shaft of the conveyor belt 421. like Figure 9 As shown, a method for winding the core of a current transformer includes the following steps: S1. Control the rotation of the internal thread vertical cylinder 305 and the internal thread horizontal cylinder 304, so that the two opposite width adjustment top rods 307 move synchronously in opposite directions, thereby pushing the side push plate 308 and the corner support 311 to move and adjust the size of the iron core winding. S2. Start the electric demolding lever 410 to extend, pushing the rotating disk 413, the anti-deviation horizontal frame 414 and the inner support demolding claw 415 to move, so that they are embedded in the groove at one end of the parallel pad 313. S3. Using the support spring 321, the lifting shaft seat 320 is pushed to slide along the inner wall of the clamping roller frame 318, and the conveying clamping roller 322 is moved along with it. The distance between the two conveying clamping rollers 322 is adjusted to clamp and fix silicon steel strips of different thicknesses. S4. Through the cooperation of the winding motor 302 and the transmission assembly, the winding frame 303 and the conveying roller 322 are driven to rotate to convey the silicon steel strip, and the electromagnet 314 is used to attract the silicon steel strip, so that the winding frame 303 can rotate to wind the silicon steel strip. S5. The infrared rangefinder 324 is used to measure the distance of the silicon steel strip in real time. When the cumulative length reaches the preset core unfolding length, the electro-hydraulic rod 325 is activated instantly to drive the shearing blade 326 to cut down quickly and cut the silicon steel strip. S6. Start the electric support rod 417 to extend. By opening the cooperation of the push block 418 and the rotating support plate 419, the two inner support demolding claws 415 expand outward inside the formed iron core, and the inner wall is completely tightened, so that the electric demolding pull rod 410 can drive the iron core to be smoothly and axially pulled out from the corner support 311. S7. The pulled-out iron core moves with the demolding mechanism and contacts the touch switch 406 on the baffle plate 424, causing the electric support rod 417 to retract and drive the inner support demolding claw 415 to retract, so that the baffle plate 424 can push the iron core out and land on the conveyor belt 421, and start the drive motor 422 for conveying.

[0022] The working principle and usage process of this invention are as follows: First, by utilizing the extension and retraction characteristics of the support spring 321, the lifting shaft seat 320 is pushed to slide along the inner wall of the clamping roller frame 318. The anti-deviation rod 319 limits the movement to prevent deviation, making it convenient for the lifting shaft seat 320 to move with the conveying clamping roller 322. The distance between the two conveying clamping rollers 322 is adjusted to facilitate the clamping and fixing of silicon steel strips of different thicknesses. Next, the internal threaded horizontal cylinder 304 is rotated, and through the engagement of the transmission gear ring 306, the two internal threaded horizontal cylinders 304 simultaneously push the width-adjusting top rods 307 on both sides of the inside to the opposite ends, pushing the side push plates 308, parallel pads 313 and corner supports 311 on both sides of the winding frame 303 to slide laterally in opposite directions, adjusting the width of the iron core winding. In addition, the actuating gear 312 is rotated, and through the engagement of the transmission gear ring 306, the two internal threaded vertical cylinders 305 are pushed to rotate synchronously, forcing the width-adjusting top rods 307 at the top and bottom of the internal threaded vertical cylinder 305 to move synchronously in opposite directions, thereby pushing the side push plates 308, parallel pads 313 and corner supports 311 at the top and bottom of the winding frame 303 to slide laterally in opposite directions, adjusting the length of the iron core winding, and thus winding iron cores of different sizes as needed, improving adaptability; Meanwhile, the tension spring 404 extends and retracts, pushing the clamping adjustment plate 403 to slide along the limiting vertical frame 401. The positioning rod 402 limits the clamping adjustment plate 403 to prevent it from shifting. This facilitates the movement of the clamping adjustment plate 403, the concave plate 405, and the anti-deviation clamping roller 407, forcing the anti-deviation clamping roller 407 to always be in contact with one end of the corner support 311. This makes it easier to clamp and fix the silicon steel strip when winding it later. When adjusting the length of the iron core winding, the movement of the side push plate 308, the parallel pad 313, and the corner support 311 pushes the anti-deviation clamping roller 407 to move, causing the clamping adjustment plate 403 to slide along the inner wall of the limiting vertical frame 401, always maintaining a close fit, which facilitates the clamping and fixing of the silicon steel strip. Next, the electric support rod 417 is extended, pushing the push block 418 to move. Through the cooperation of the rotating support plate 419, the two inner support demolding claws 415 are forced to move in opposite directions, increasing the length of the telescopic connecting rod 416 so that the distance between the two inner support demolding claws 415 is equal to the distance between the two corner support brackets 311 and equal to the adjusted iron core winding width, forcing the inner support demolding claws 415 to correspond to the grooves on the parallel pad plate 313. Then, the electric demolding rod 410 is extended, pushing the rotating disk 413, the anti-deviation cross frame 414 and the inner support demolding claw 415 to move, forcing the inner support demolding claw 415 to embed into the groove on the parallel pad 313. At the same time, when the electric demolding rod 410 moves, the electric demolding rod 410 is assisted and supported by the cooperation of the translation slide 411 and the limiting lug 412, thereby improving the stability of the electric demolding rod 410 during extension and retraction. Next, the winding motor 302 is started to rotate, and through the cooperation of the transmission shaft 327, the transmission sprocket 328 and the transmission chain 329, the conveying clamp roller 322 is driven to rotate, conveying the clamped silicon steel strip, so that one end of the silicon steel strip extends out, and then through the cooperation of the electromagnet 314, the silicon steel strip is attracted, so that one end of the silicon steel strip is tightly attached to the corner support frame 311, which facilitates the winding motor 302 to drive the winding frame 303 to rotate, and simultaneously drive the internal thread horizontal cylinder 304, the internal thread vertical cylinder 305, the width adjusting top rod 307, the side push plate 308 and the corner support frame 311 to rotate, so as to wind the silicon steel strip to form an iron core; Meanwhile, during the winding process, the tension spring 404 pushes the clamping adjustment plate 403, concave plate 405 and anti-deviation clamping roller 407 to descend, clamping the silicon steel strip to ensure the tension of the winding. The anti-deviation retaining ring 408 and the inner support demolding claw 415 work together to limit the silicon steel strip and prevent deviation, ensuring the effect of iron core winding. During winding, the inner support demolding claw 415, the anti-deviation horizontal frame 414 and the rotating disk 413 are pushed to rotate, so that the inner support demolding claw 415 is wound inside the iron core, which provides convenience for subsequent support demolding. In addition, during the winding of silicon steel strip, the infrared rangefinder 324 measures the silicon steel strip in real time and records the conveying distance of the silicon steel strip. When the winding distance of the iron core is met, the electro-hydraulic rod 325 is extended to push the shearing blade 326 down to cut the silicon steel strip and complete the winding of the iron core. At the same time, the rotation of the winding motor 302 and the attraction force of the electromagnet 314 are stopped. Next, after the iron core is wound, the electric support rod 417 extends and, through the cooperation of the push block 418 and the rotating support plate 419, pushes the two inner support demolding claws 415 to slide synchronously in opposite directions along the inner wall of the anti-deviation cross frame 414. This increases the distance between the two inner support demolding claws 415, making it easier to support the inner wall of the wound iron core. Subsequently, the electric demolding pull rod 410 is activated to retract, moving the rotating disk 413, the anti-deviation cross frame 414, and the inner support demolding claws 415 to pull the wound iron core out of the corner support frame 311. Then, as the electric demolding pull rod 410 continues to pull the iron core, it contacts the touch switch 406 at one end of the stop push plate 424, causing the electric support rod 417 to retract and reset. By opening the cooperation of the push block 418 and the rotating support plate 419, the two inner support demolding claws 415 are pulled to move relative to each other, releasing the support on the iron core. Finally, as the electric demolding lever 410 continues to move, the iron core supported on the inner support demolding claw 415 is pushed out by the stop push plate 424, so that the iron core falls onto the conveyor belt 421. At the same time, the touch switch 406 synchronously controls the drive motor 422 to rotate, which rotates the conveyor belt 421, facilitating the conveying of the iron core that has fallen onto the conveyor belt 421. After the iron core is conveyed away, the electric demolding lever 410 is extended, pushing the rotating disk 413, the anti-deviation cross frame 414 and the inner support demolding claw 415 to reset, forcing the inner support demolding claw 415 to re-insert into the groove at one end of the parallel pad 313. Then, the electromagnet 314 is activated to attract one end of the new silicon steel strip to one end of the corner support frame 311. Through the cooperation of the winding motor 302, the drive shaft 327, the drive sprocket 328 and the drive chain 329, the silicon steel strip is conveyed and wound to process and wind another iron core.
