[0017] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0018] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0019] according to Figure 1 , Figure 2 , Figure 3As shown, a lever-type wire pay-off buffer frame includes a pay-off drum 1 and a pay-off frame 2, wherein a pay-off buffer device 3 is provided on one side of the pay-off frame 2. A first wire wheel 5-1 is arranged on the top, and the wire-releasing buffer device 3 includes a fixed arm 31 and a movable arm 32, on which a second wire wheel 5-2 and a third wire wheel 5-3 are arranged respectively, and the movable arm 32 is movably arranged on the fixed arm 31 through a pin shaft, and a pair of spring adjustment devices 33 are symmetrically arranged on both sides of the movable arm 32 away from the fixed arm 31, and a spring 34 for adjusting the tension is arranged between the spring adjustment device 33 and the bottom plate, which can effectively relieve the tension of the steel wire during the start-stop process; the spring adjustment device 33 includes a perforated plate 331, a C-shaped frame 332, and a threaded rod 333, and the perforated plate 331 is rotatably arranged on the movable arm 32 through a pin shaft, so that the perforated plate 331 keeps the spring adjustment device 33 facing downward when the movable arm 32 moves up and down to reduce the oblique force received, thereby improving the stability of the device and extending the service life of the device; the threaded rod 333 is adjustably arranged on the perforated plate 33 through a nut 1, a C-frame 332 is arranged at the bottom of the threaded rod 333, a hanging hole 6 is arranged on the bottom plate at a position opposite to the spring adjustment device 33, hooks are arranged at both ends of the spring 34, which are respectively hooked on the C-frame 332 and the hanging holes 6 on the bottom plate to fix the spring 34 on the wire-releasing buffer device 3, and the distance between the C-frame 322 and the hanging hole 6 on the bottom plate can be adjusted by the threaded rod according to different specifications of the steel wire, so as to adjust the tightness of the spring 34 to adapt to different working requirements; anti-collision pads 4 are arranged on the wire-releasing frame 2 and above and below the movable arm 32, which can limit the range of movement of the movable arm 32 and play a certain protective role on the movable arm 32 and the equipment; a sensor 7 is arranged on one side of the wire-releasing frame 2. When the steel wire is subjected to excessive tension and the movable arm is lifted too high, the equipment can be urgently shut down and stopped through the sensor 7; the movable arm 32 is set as a hollow structure, which allows the steel wire to pass through the middle of the movable arm 32, so that the movable arm 32 and the wire wheel are evenly stressed, thereby extending the service life of the device.

[0020] During use, the steel wire first enters from above the first wire wheel 5-1 on the pay-off frame 2, and then passes through below the second wire wheel 5-2 on the movable arm 32. The steel wire continues to move forward and passes through the middle of the movable arm 32. Finally, the steel wire leaves from the upper side of the third wire wheel 5-3 on the fixed arm 31 and enters the next process. When the tension is strong, the steel wire forms a height difference due to passing through the first wire wheel 5-1, the second wire wheel 5-2 and the third wire wheel 5-3 at different heights. When the steel wire passes through the movable arm 32 that can move up and down, it will naturally lift the movable arm 32. A spring is installed on the movable arm 32 to generate a pulling force 34 to reduce the stress on the steel wire. Tension, the pulling force of the spring 34 interacts with the tension of the steel wire, so that the steel wire will not be damaged due to excessive tension during operation. When the tension is small, the movable arm 32 will sink. In extreme cases, such as when the steel wire is subjected to excessive force and the movable arm 32 is lifted to a certain height, the movable arm 32 will be restricted by the anti-collision pad 4 and the sensor 7 will be triggered to shut down the equipment urgently to prevent the equipment from continuing to run. The steel wire will break due to excessive stretching, thereby avoiding potential damage to materials or equipment. The spring adjustment device 33 can adjust the tightness of the spring 34 to adapt to the specific requirements under various working conditions and ensure that the working needs of steel wires of different specifications are met.

[0021] The utility model is cleverly designed. Through the arrangement of the wire-releasing buffer device 3, the utility model can effectively alleviate the tension exerted on the steel wire during the start-stop process and reduce the risk of steel wire breakage. The tightness of the spring 34 can be adjusted through the spring adjustment device 33, so that the device can adapt to the working requirements of steel wires of different specifications, thereby improving the versatility and applicability of the device. When the steel wire is subjected to excessive tension, the movable arm 32 will trigger the sensor 7, thereby urgently stopping the operation of the equipment and avoiding potential dangers and equipment damage caused by steel wire breakage.

[0022] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
