Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.

[0017] The following will be combined with the instructions Figure 1-2 The above technical solutions are described in detail with specific implementation methods:

[0018] The utility model provides a wire rod uncoiler, comprising a frame 1, an uncoiler, a guide device, a tension adjustment device, and a drive device; the uncoiler, guide device, tension adjustment device, and drive device are all mounted on the frame 1; the uncoiler comprises a reel 2 and a support shaft 3, the reel 2 being rotatably mounted on the support shaft 3; the guide device comprises a plurality of guide rollers 4, the guide rollers 4 being used to guide the movement direction of the wire rod; the tension adjustment device comprises a tension sensor 5 and a tension adjustment mechanism, the tension sensor 5 being used to detect the tension of the wire rod, and the tension adjustment mechanism adjusting the tension of the wire rod according to the detection result of the tension sensor 5; the drive device is used to drive the uncoiler and guide device to operate. As a preferred embodiment, the surface of the reel 2 is provided with anti-slip grooves to increase the friction between the wire rod and the reel 2.

[0019] The support shaft 3 is mounted on the frame 1 in the following manner: Each end of the support shaft 3 is secured to the frame 1 via high-strength bearing blocks. Bolts securely connect the bearing blocks to the frame 1, ensuring that the support shaft 3 can stably withstand the weight of the reel 2 and the various forces generated by its rotation during the unwinding process. The reel 2 and support shaft 3 utilize a transition fit or interference fit to ensure a secure fit of the reel 2 on the support shaft 3 and prevent loosening or displacement during high-speed rotation. Positioning rings are also installed at each end of the reel 2 to further limit axial movement of the reel 2.

[0020] The guide rollers 4 are mounted on brackets via bearings at both ends. The brackets are secured to the frame 1 by welding or bolting. This ensures that the guide rollers 4 can rotate flexibly, guiding the movement of the wire rod. Multiple guide rollers 4 are arranged in a specific layout, tailored to the wire rod's unwinding path and processing requirements. For example, they can be arranged in a staggered arrangement or in parallel horizontally to effectively guide the wire rod.

[0021] The tension adjustment device includes a tension sensor 5 and a tension adjustment mechanism. The tension sensor 5 is fixed to the frame 1 through a mounting base, usually installed on the path of the wire rod to accurately detect the tension of the wire rod. The mounting base is connected to the frame 1 by bolts or welding to ensure that the sensor is firmly installed and accurately positioned. The tension adjustment mechanism includes a hydraulic cylinder 6 and an adjusting roller 7. The bottom of the hydraulic cylinder 6 is connected to the fixed base on the frame 1 by a pin or bolt. The fixed base is specially designed to withstand the reaction force generated by the hydraulic cylinder 6 during operation. The two ends of the adjusting roller 7 are mounted on a movable frame through bearings, and the movable frame is connected to the piston rod of the hydraulic cylinder 6. When the hydraulic cylinder 6 is working, the extension and contraction of the piston rod drives the movable frame to move up and down, thereby adjusting the position of the adjusting roller 7 and adjusting the tension of the wire rod.

[0026] During use, the present invention places a coil of wire rod on a reel 2, leads the head of the wire rod through a guide device, and then activates the drive device, which drives the unwinding device and the guide device to operate, unwinding the wire rod. During the unwinding process, the tension sensor 5 detects the tension of the wire rod in real time. The control system 11 controls the tension adjustment mechanism to adjust the tension of the wire rod based on the detection result of the tension sensor 5 to ensure the stability of the tension.
