[0002] Steel wire is one of the four major types of steel: plate, tube, profile and wire. It is a reprocessed product made from hot-rolled wire rods by cold drawing. When processing steel wire, the wire rod wound on the reel must first be unwound. When unwound, the wire rod on the reel moves on the production line via the guide wheel under the traction of the traction mechanism. Since the arrangement of the wire rod wound on the reel is irregular, during the unwound process, the outer wire rod under tension is prone to lateral slippage relative to the inner wire rod, thereby reducing the unwound accuracy of the wire rod.
[0003] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0023] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.
[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0025] Reference Figures 1 to 5 As shown, the utility model provides a wire rod pay-off device, comprising: a pay-off frame 1, a bearing platform 3 and a guide structure 4.
[0026] A reel 2 is rotatably mounted on the pay-off frame 1 , the central axis of the reel 2 is arranged in the horizontal direction, and a multi-layer wire rod 21 to be processed is wound on the reel 2 .
[0027] A bearing platform 3 is disposed on one side of the reel 2 , and a guide structure 4 is mounted on the bearing platform 3 . The guide structure 4 includes a guide wheel 41 and a sliding seat 42 .
[0028] See also Figure 2 and Figure 3 As shown, the bearing platform 3 is provided with a slide groove, which is arranged along the axial direction of the reel 2. A slider is formed at the bottom of the sliding seat 42, and the slider at the bottom of the sliding seat 42 is slidably arranged in the slide groove of the bearing platform 3.
[0029] The central axis of the guide wheel 41 is arranged vertically, and the guide wheel 41 is rotatably mounted on the sliding seat 42. The wire rod 21 is wound around one side of the guide wheel 41. Preferably, the wheel surface of the guide wheel 41 is formed with an annular groove a, and the wire rod 21 is movably embedded in the annular groove a. The end of the wire rod 21 away from the reel 2 is arranged on the other side of the guide wheel 41, and the end of the wire rod 21 away from the reel 2 is connected to a traction mechanism (wire drawing machine). The support 31 is installed on the bearing platform 3, and the support 31 is arranged on one side of the guide wheel 41. A tension spring 32 is connected between the sliding seat 42 and the support 31.
[0030] In this embodiment, the pay-off frame 1 is equipped with a damping mechanism. When the traction mechanism pulls the wire rod 21, the reel 2 performs passive pay-off. When the reel 2 passively pays off the wire, the damping mechanism provides resistance to the reel 2, thereby maintaining the tension of the wire rod 21. The traction mechanism and the damping mechanism on the pay-off frame are prior art and will not be described in this embodiment.
[0031] See also Figure 1 As shown, in this embodiment, a plurality of pay-off frames 1 are provided, and the plurality of pay-off frames 1 are spaced apart along the axial direction of the reel 2. Under the guidance of the guide wheel 41, the wire rods on the plurality of reels 2 are paid out synchronously, thereby improving the pay-off efficiency of the wire rods.
[0032] When the traction mechanism pulls one end of the wire rod 21 for pay-off, the wire rod 21 is wound around one side of the guide wheel 41 and drives the guide wheel 41 and the sliding seat 42 to move in a direction away from the support 31. Under the action of the tension spring 32, the guide wheel 41 and the sliding seat 42 maintain dynamic balance. When the outer wire rod on the reel 2 slips laterally relative to the inner wire rod, the tension loss of the wire rod 21 is reduced by the pulling of the tension spring 32, thereby reducing the influence of the lateral slip of the outer wire rod relative to the inner wire rod on the pay-off accuracy of the wire rod.
[0033] As a preferred embodiment, a guide roller assembly 7 is provided between the traction mechanism and the guide wheel 41 through a support frame 6. The guide roller assembly 7 includes an upper roller shaft 71 and a lower roller shaft 72 which are arranged opposite to each other, and the upper roller shaft 71 and the lower roller shaft 72 are rotatably mounted on the support frame 6. The upper roller shaft 71 and the lower roller shaft 72 are respectively formed with a limiting ring groove d, and a material connection gap is formed between the limiting ring grooves d of the upper roller shaft 71 and the lower roller shaft 72, and the wire rod 21 can be movably inserted in the material connection gap.
[0034] By providing the guide roller assembly 7, the wire rod unwinding can be made more accurate and stable.
[0035] See also Figure 2 and Figure 4 As shown, in this embodiment, a guide assembly 5 is installed on the support platform 3 , and the guide assembly 5 is arranged between the guide structure 4 and the reel 2 .
[0036] Specifically, the guide assembly 5 includes a slide 51, a rotating seat 52 and a supporting wheel 53. The support platform 3 is provided with a guide groove c, which is arranged along the axial direction of the reel 2, and the guide groove c is arranged on the side of the guide wheel 41 facing the reel 2. A limit block is formed at the bottom of the slide 51, and the limit block at the bottom of the slide 51 is slidably arranged in the guide groove c.
[0037] The rotating seat 52 is rotatably mounted on the top of the slide 51, and two supporting plates 521 are vertically arranged opposite to each other on the top of the rotating seat 52. The central axis of the supporting wheel 53 is arranged in the horizontal direction, and the supporting wheel 53 is rotatably mounted between the two supporting plates 521. In this embodiment, the upper side of the supporting wheel 53 is flush with the top of the guide wheel 41, and the wheel surface of the supporting wheel 53 is formed with an annular groove b, and the wire rod 21 is movably embedded in the annular groove b of the supporting wheel 53.
[0038] As the wire is released, the wire rod on the drum 2 is reduced layer by layer. At this time, a height difference is generated between the wire rod 21 on the drum 2 and the annular groove a of the guide wheel 41. When the height difference is large, the wire rod 21 will scratch the groove wall of the annular groove a or even detach from the annular groove a. In this embodiment, by providing a support wheel 53, the wire rod 21 is smoothly connected from the annular groove b of the support wheel 53 to the annular groove a of the guide wheel 41, thereby avoiding the influence of the height difference between the wire rod 21 and the annular groove a of the guide wheel 41 on the wire release, and further improving the wire release accuracy of the wire rod 21.
[0039] The utility model discloses a wire rod pay-off device, a bearing platform is arranged on one side of the pay-off frame, a sliding seat and a guide wheel are installed on the bearing platform, and a tension spring is connected between the sliding seat and the support of the bearing platform, when a traction mechanism stretches the wire rod for pay-off, the wire rod is wound around one side of the guide wheel and drives the guide wheel and the sliding seat to move in a direction away from the support, and under the action of the tension spring, the guide wheel and the sliding seat maintain dynamic balance, and when the outer wire rod slips laterally relative to the inner wire rod, the tension loss of the wire rod is reduced by the pulling of the tension spring, thereby reducing the influence of the lateral slip of the outer wire rod relative to the inner wire rod on the pay-off accuracy of the wire rod.
[0040] As the wire is paid out, the wire rod on the drum is reduced layer by layer, resulting in a height difference between the wire rod on the drum and the guide wheel. When the height difference is large, the wire rod will scratch the groove wall of the annular groove of the guide wheel or even detach from the annular groove, resulting in damage to the wire rod and a decrease in the wire payout accuracy. The wire rod payout device of the utility model provides a guide assembly between the guide structure and the drum. When there is a height difference between the wire rod on the drum and the guide wheel, the wire payout height of the wire rod is maintained by the support wheel, so that the wire rod maintains a stable connection with the guide wheel under the guidance of the support wheel, thereby further improving the wire payout accuracy.
