3. The high-speed wire baling machine according to claim 2, characterized in that, A limit plate is provided on the outside of the guide wheel bracket in the middle and corresponding to the spring.

4. A packaging method for a high-speed wire baling machine according to any one of claims 1-3, characterized in that, Includes the following steps: Step 1: After the C-hook transports the loose coil to the packing station via the conveyor chain and stabilizes it, the pressure plates on both sides inside the packing machine move towards the center simultaneously. At the same time, the support rises to lift the coil and remove it from the C-hook. The pressure plates are driven by hydraulic cylinders and lock after reaching the designated position. Simultaneously, the four packing heads inside the packing machine feed, clamp, pull, and twist the thread to form four packing hoops. After twisting is completed, the two pressure plates will retract, and the support will descend, returning to the initial position. The first packing is completed. If the coil is not round enough, the two rollers driven by the hydraulic motor will rotate in the same direction to rotate the packed coil, making the surface of the coil smoother and rounder. Step 2: The length and diameter of the packing coils are different, but the distribution of the packing hoops is 90° vertically. To complete the packing of eight hoops, the coil with four hoops needs to be rotated 45° by the rollers and then packed a second time. The packing hoops of the coil that has been rotated 45° are located directly below, which is the center of the two round rollers. Step 3: Install a detection structure at the center of the two rolling rollers to detect the position of the packing hoop. Several guide wheels and guide wheel supports form a guide wheel mechanism. When the packing machine bracket rises, the rolling rollers and guide wheel mechanism rise together. Regardless of the outer diameter of the coil, the guide wheel mechanism will be tightly pressed against the coil due to the compression of the lower spring, while the upper spring is not compressed. The rolling rollers rotate. When the coil packing hoop passes the left or right guide wheel, or when the outside of the coil is uneven, the entire guide wheel mechanism will descend, and the middle guide wheel will descend together. The diameter of the packing hoop is 8mm. When the coil packing hoop rotates to the middle guide wheel, the middle guide wheel will descend 8mm, and the middle guide wheel support and its end detection block will also descend 8mm, causing the proximity switch signal to be lost. By accurately detecting the packing hoop, it is determined that the packing hoop is at the bottom, thus determining that the coil has rotated 45 degrees, thereby determining the position of the secondary packing. Step four: After determining the location for secondary packaging in step three, repeat the packaging machine's program operation once to perform secondary packaging on the coil, achieving eight-hoop packaging.

5. A packaging method for a high-speed wire baling machine according to claim 4, characterized in that, In the aforementioned steps, the secondary packaging stroke needs to be controlled in order to prevent the primary packaging hoop from loosening during secondary packaging and to reduce the pressure value of the pressure plate during the secondary packaging process of the packaging machine.
