[0016] The tensioning assembly 4 includes a fixed guide wheel 41 and a movable guide wheel 44. The fixed guide wheel 41 is installed on the front side of the main unit 1 and is symmetrically distributed between the outer bracket 2 and the drive wheel 11. A slide rail 42 is fixed on the front side of the main unit 1 and between the fixed guide wheels 41. A slider 43 is slidably connected on the slide rail 42. The movable guide wheel 44 is installed on the slider 43. A sliding groove 45 is opened on the front side of the slide rail 42. A telescopic rod 46 is fixed at one end of the slider 43 located in the sliding groove 45. The upper end of the telescopic rod 46 extends out of the slide rail 42 and is fixed with an end plate 47. A tension spring 48 is fixed between the end plate 47 and the upper end of the slide rail 42.

[0017] The adjusting component 3 includes a sliding block 31, which is slidably connected inside the outer bracket 2 and aligned with the upper conveyor wheel 22. The upper conveyor wheel 22 is installed at the front end of the sliding block 31. An adjusting groove 32 is provided on the outer bracket 2. A lifting plate 33 is slidably connected inside the adjusting groove 32. A connecting rod 34 is fixed at the bottom of the lifting plate 33 and is fixed at the bottom of the sliding block 31. An adjusting screw 35 is rotatably connected to the upper end of the lifting plate 33. The adjusting screw 35 is threadedly connected to the outer bracket 2 and extends out of the outer bracket 2.

[0018] Working principle: First, connect the entire device to an external power source. Then, pass the wire through the perforation, between the bottom conveyor wheel 21 and the upper conveyor wheel 22, then through the tensioning assembly 4, and finally through the drive wheel 11 to transport the wire to the cutting blades 13 for cutting. During this process, the downward pressure of the upper conveyor wheel 22 limits the wire transport, preventing jumping and maintaining straight wire transport. In operation, the rotation of the adjusting screw 35 can be used to achieve extension and retraction, thereby driving the lifting plate 33 to extend and retract. Through the transmission of the connecting rod 34, the sliding block 31 can be driven to slide up and down, ultimately achieving the cutting of the upper... The up-and-down adjustment of the end conveyor wheel 22 is used to prevent excessive pulling of the wire when the drive wheel 11 starts to pull the wire. The instantaneous tension will cause the surface tension of the wire to increase rapidly. At this time, the lifting and lowering of the movable guide wheel 44 can play a buffering role to avoid excessive pulling on the wire. At the end of the pulling, the movable guide wheel 44 can be reset to tighten the wire again, further avoiding the problem of wire loosening and ensuring stable wire conveying. During this process, the extension and retraction of the movable guide wheel 44 is mainly achieved by the extension and retraction of the tension spring 48, which changes the position of the end plate 47 and the telescopic rod 46, thereby realizing the purpose of sliding the slider 43 on the slide rail 42.
