Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Please see Figures 1-4 As shown, this embodiment is a tension-adjusting straightening frame for multi-strand wires, comprising:

[0027] Frame 1, guide wheel bracket 2, lifting screw 3, guide component 5, connecting plate 6, adjusting component 7, and permanent magnet brake 8;

[0028] The guide wheel bracket 2 is fixed to the top of the frame 1, the lifting screw 3 is set inside the guide wheel bracket 2, the guide 5 is set outside the lifting screw 3, the connecting plate 6 is fixed inside the guide wheel bracket 2, the adjusting component 7 is set inside the connecting plate 6, and the permanent magnet brake 8 is set at one end of the connecting plate 6.

[0029] The frame 1 serves as the main support structure of the device, bearing the installation and fixing of all components. The guide wheel bracket 2 is fixed on the top of the frame 1 and is used to install the lifting screw 3, guide column 4 and connecting plate 6. The lifting screw 3 is used to adjust the height of the lifting slider 51 to adapt to different wire diameters or process requirements. The guide 5 is used to transmit the cable to the required position. The connecting plate 6 is fixed inside the guide wheel bracket 2 and is used to install the adjusting component 7 and permanent magnet brake 8. The adjusting component 7 is used to adjust the tension of the cable transmission. The permanent magnet brake 8 steplessly adjusts the resistance of the tension wheel 74 through the action of the magnetic field to achieve high-precision tension control.

[0030] There are three sets of lifting screws 3 and two sets of connecting plates 6. The lifting screw 3 on one side is located between the two sets of connecting plates 6.

[0031] The guide component 5 includes a lifting slider 51, a connecting shaft 52, a first bearing 53, and a multi-strand straightening wheel 54; the lifting slider 51 is slidably connected to the outside of the lifting screw 3, the connecting shaft 52 is fixed inside the lifting slider 51, the inner ring of the first bearing 53 is fixed to the outer surface of the connecting shaft 52, and the multi-strand straightening wheel 54 is fixed to the surface of the outer ring of the first bearing 53. The multi-strand straightening wheel 54 is multi-grooved.

[0032] The lifting slider 51 carries the connecting shaft 52 and the multi-strand straightening wheel 54, and is used to adjust the height of the straightening wheel. The connecting shaft 52 transmits the lifting motion of the lifting slider 51 to the straightening wheel assembly. The first bearing 53 reduces the frictional resistance when the straightening wheel rotates, ensuring that it can rotate freely with the direction of cable travel. The multi-strand straightening wheel 54 is used to flatten and arrange the multi-strand wires, eliminate bending or tangling, and ensure that the cable is straight and uniform.

[0033] Guide posts 4 are attached to the outer surfaces of both sides of the lifting slider 51, and the guide posts 4 are fixed inside the guide wheel bracket 2;

[0034] The guide column 4 limits the horizontal offset of the lifting slider 51, ensuring that it rises and falls smoothly in the vertical direction;

[0035] The adjusting component 7 includes a bearing housing 71, a second bearing 72, and a mounting shaft 73; the bearing housing 71 is fixed inside the connecting plate 6, the second bearing 72 is disposed inside the bearing housing 71, the mounting shaft 73 is fixed inside the inner ring of the second bearing 72, and the mounting shaft 73 is connected to the output end of the permanent magnet brake 8.

[0036] A tension wheel 74 is fixed to the outer surface of the mounting shaft 73. The tension wheel 74 has a multi-groove shape.

[0037] The bearing housing 71 provides a stable mounting position for the mounting shaft 73 to ensure its concentricity. The second bearing 72 reduces the friction when the tension wheel 74 rotates, achieving smooth transmission. The mounting shaft 73 transmits braking torque to the tension wheel 74 and supports its rotational movement. The tension wheel 74 applies a reverse torque through the permanent magnet brake 8 to dynamically adjust the cable tension and prevent the tension from being too loose or too tight.

[0038] Working principle: When the cable needs to be conveyed to the required position, the lifting slider 51 is first adjusted to the required height using the lifting screw 3. When the cable enters the device, under the setting of the first bearing 53 and the second bearing 72, the multi-strand straightening wheel 54 and the tension wheel 74 move in the same direction as the cable. Under the setting of the permanent magnet brake 8, a torque opposite to that of the cable is applied to the tension wheel 74, thereby adjusting the tension of the cable.

[0039] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
