[0053] The stability of the working state of the leveling plate 707 on both sides of the limit block 706 can be ensured, thereby ensuring the stability of the subsequent automatic and stable pushing and leveling work of the leveling plate 707 on the strip.

[0054] A method for changing the hardness value of an ultra-wide strip comprises the following steps:

[0055] S1: disassembling and assembling the unwinding roller 13 and the winding roller 17; the flange 14 can be used to conveniently and efficiently disassemble and assemble the unwinding roller 13 and the winding roller 17, thereby ensuring the convenience and stability of subsequent processing of multiple batches of copper alloy strips;

[0056] S2: Adjust the limit; by using the cooperation of the limit assembly 5 and the self-locking assembly 6, the copper alloy strips of different widths and thicknesses can be conveniently and efficiently limited, thereby ensuring the stability and safety of the subsequent processing of the copper alloy strips;

[0057] S3: Adjust the guide; the first guide roller 9 and the second guide roller 12 can be used to stably guide the copper alloy strip, thereby effectively avoiding the problem of excessive hardness value caused by repeated winding tension of the strip, resulting in unqualified performance of the soft transformer product;

[0058] S4: Automatic leveling; during the guiding process of the first guide roller 9, the copper alloy strip can drive the first guide roller 9 to rotate, and the transmission belt 10 can drive the reciprocating screw 705 to rotate stably, thereby driving the leveling plate 707 on the limit block 706 to perform automatic and stable back and forth reciprocating motion, thereby automatically leveling the copper alloy strip in the processing process, and effectively preventing the copper alloy strip from wrinkling during the processing process, which may cause the copper alloy strip to be torn, cut, or other damage.

[0059] It should be noted that the present invention is a device and method for changing the hardness value of an ultra-wide strip. First, when the copper alloy strip needs to be transferred to a cleaning line device for surface treatment such as degreasing, pickling or passivation, the staff can install the unwinding roller 13 with the copper alloy strip wound on it on the right transmission shaft 15 through the flange 14. Then the staff can install the winding roller 17 to be used on the left transmission shaft 15 through the flange 14. At this time, the staff can pull one end of the copper alloy strip on the unwinding roller 13 and wind it around the winding roller 17. Then the staff can rotate the fixed shaft 4 on the mounting plate 3. At this time, under the rotation of the fixed shaft 4, the pulling ropes 502 on both sides can be automatically wound through the fixed coil 501, and the corresponding guide wheels 503 can drive the connecting plates 504 on both sides to the center on the fixed plate 2 at the same time. The first limit plate 507 can be driven to move stably downward by the rotation of the one-way threaded rod 506. At this time, under the joint action of the first limit plate 507 and the second limit plate 508, the small balls 509 can be used to conveniently and stably limit the copper alloy strips of different thicknesses, thereby ensuring the stability of the subsequent transmission state of the copper alloy strip, effectively preventing the copper alloy strip from shifting in position during the processing and affecting the subsequent winding work, thereby effectively preventing the staff from repeatedly winding the strip to ensure the stability of the winding transmission state, resulting in excessive tension and excessive hardness.

[0060] When the fixed shaft 4 rotates, each block 603 can be driven to rotate along the inclined surface of the slot 602 inside the connecting sleeve 601. At this time, each block 603 can always fit with the slot 602 in combination with the corresponding reset spring 604. At this time, under the action of the right-angled surface of the slot 602, each block 603 can be automatically engaged, thereby effectively preventing the fixed shaft 4 from rotating, thereby ensuring the stability of the subsequent limiting protection work of the copper alloy strip. After the copper alloy strip is processed, the staff only needs to pull the connecting rope 605 outward. At this time, the connecting rope 605 can drive each block 603 to rotate out of the slot 602. At this time, under the action of the fixed springs 505 on both sides, the corresponding connecting plates 504 can be driven to move outward and reset at the same time, thereby driving the pulling rope 502 to move and reset, thereby ensuring the stability and convenience of the subsequent multiple operations of the device.

[0061] Then the staff can rotate the bidirectional threaded rod 701. At this time, the rotation of the bidirectional threaded rod 701 can drive the sliding blocks 702 on both sides to move outward at the same time. At this time, the sliding blocks 702 on both sides combined with the corresponding support rods 703 can push the guide plate 704 to move downward stably, and then can drive the first guide roller 9 to move downward stably through the connecting plate 8. Combined with the second guide rollers 12 on both sides, the copper alloy strip can be stably guided. In the process of the movement of the guide plate 704, the flat plates 707 on both sides can be driven to stably fit the copper alloy strip at the second guide roller 12. Then the staff can control to start the servo motor 16. At this time, the servo motor 16 Under the action of, the copper alloy strip can be stably wound by the winding roller 17. At this time, during the transmission process of the copper alloy strip, the first guide roller 9 can be driven to rotate automatically, and then the first guide roller 9 can drive the reciprocating screw 705 to rotate automatically through the transmission belt 10, and then can drive the limit block 706 to perform stable back and forth reciprocating motion in the guide plate 704. At this time, under the movement of the limit block 706, the strip on the second guide roller 12 is automatically and stably pushed back and forth to be leveled through the leveling plates 707 on both sides, thereby effectively avoiding wrinkles in the strip during transmission, causing damage to the copper alloy strip such as tearing and cutting, and increasing the diversity and safety of the device.

[0062] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources.
