By adjusting the mechanism 5, when stacking iron cores of different diameters, the slot on the outside of the iron core is first aligned with the positioning strip 510. The drive motor 506 is started by the switch 3, which drives the turntable 507 to rotate, causing the rotary slot 508 to rotate, which in turn causes the connecting shaft 504 to move, causing the slider 502 to slide on the outside of the slide rod 509, which drives the positioning plate 503 to move, so that the positioning plate 503 is in contact with the outside of the iron core. At the same time, the positioning strip 510 is located in the slot on the outside of the iron core, which makes it easy to adjust according to the diameter of the iron core without stopping the machine to replace the guide post, improving efficiency and enhancing the applicability of the device.

[0018] Please refer to it again. Figure 4 and Figure 5The connecting mechanism 6 includes a mounting block 601 fixed to the end of the output shaft of the electric telescopic rod 401. The mounting block 601 has an internal mounting cavity 602. A connecting groove 603 is formed through the center of the bottom of the mounting block 601. Limiting rods 604 are symmetrically fixed between the two sides of the mounting cavity 602. A sliding plate 605 slides symmetrically on the outer side of the limiting rods 604. A push rod 606 is fixed to the center of the top of one side of the sliding plate 605. A strong spring 607 is fixed to the top of one side of the sliding plate 605. Insertion rods 608 are symmetrically fixed to the bottom of one side of the sliding plate 605. A second concave frame 609 is fixed to the center of the top of the pressure plate 402.

This makes it easy to adjust the pressure plate 402 according to the diameter of the iron chip, making it convenient to press different types of iron chips, improving the applicability of the device, facilitating replacement, and improving the convenience of replacement.

[0019] When using this utility model: Working principle: First, align the slot on the outer side of the iron chip with the positioning strip 510. Start the drive motor 506 via switch 3, causing the turntable 507 to rotate, which in turn rotates the rotating groove 508, moving the connecting shaft 504. This causes the slider 502 to slide outside the slide rod 509, moving the positioning plate 503 so that it fits against the outer side of the iron chip. Simultaneously, the positioning strip 510 is positioned in the slot on the outer side of the iron chip. Then, turn off the drive motor 506 via switch 3 to stack the iron chips, ensuring the positioning strip 510 is positioned in one of the slots on the outer side of the iron chip for easy alignment. Next, press the actuating rod 606, moving the sliding plate 605 and stretching the strong spring 607, simultaneously moving the insertion rod... 608 is removed from the insertion hole 610, releasing the fixation of the second concave frame 609, disassembling the pressure plate 402, and then installing the new pressure plate 402, so that the second concave frame 609 is embedded in the connecting groove 603. The push rod 606 is loosened, and the reset of the strong spring 607 causes the slide plate 605 to drive the insertion rod 608 to reset, so that the insertion rod 608 is embedded in the insertion hole 610, fixing the second concave frame 609, thereby fixing the pressure plate 402, which is convenient for adjusting the pressure plate 402 according to the diameter of the iron chip.
