Description

Technical Field

[0001] This utility model relates to the field of structural mechanics technology, and in particular to a wire feeding frame with automatic tension adjustment function. Background Technology

[0002] In the processing of continuous materials such as wires and cables, textiles and chemical fibers, and metal wire mesh, the first and most critical step is the unwinding of the wire, the core requirement of which is to ensure that the tension of the wire remains constant during the unwinding process.

[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: Most wire feeding machines on the market use fixed friction brakes or manually adjustable brakes. Their braking torque cannot be automatically adjusted according to changes in wire feeding speed, start-stop acceleration, and wire reel diameter. When accelerating or starting with a full reel, the huge inertial torque can easily cause tension spikes, resulting in wire breakage. When decelerating or feeding to an empty reel, the reduced inertia leads to relatively excessive braking force, causing tension relaxation and wire vibration. Operators need to frequently intervene manually based on experience, which not only results in lagging adjustment and poor accuracy but also greatly increases labor intensity and production uncertainty.

[0004] To address these issues, we provide a wire feeding frame with automatic tension adjustment. Summary of the Invention

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of inconsistent tension. To address this, we propose a wire feeding frame with automatic tension adjustment function.

[0006] To achieve the above objectives, this application adopts the following technical solution: a wire feeding frame with automatic tension adjustment function, comprising a first support frame, wherein a support platform is fixedly connected to the surface of the first support frame; an adjustment component is provided on the surface of the support platform, the adjustment component comprising a fixing block fixedly connected to the top of the support platform, a support column fixedly connected to the top of the support platform, and a first rotating shaft rotatably connected to the inner cavity of the support column, the adjustment component being used to automatically adjust the surface tension of the fed wire; a rotating component is provided in the inner cavity of the first support frame, the rotating component comprising a rotating groove formed in the inner cavity of the first support frame, a roller slidably connected to the inner cavity of the rotating groove, and a roller rotatably connected to the inner cavity of the roller, the rotating component being used to complete the wire feeding operation.

[0007] Preferably, a wheel is fixedly connected to the surface of the first rotating shaft, and a first extension rod is fixedly connected to the surface of the wheel.

[0008] Preferably, a second extension rod is fixedly connected to the surface of the rotating wheel, and a threader is fixedly connected to one end of the first extension rod.

[0009] Preferably, a spring is fixedly connected to the bottom of the second extension rod, and one end of the spring is fixedly connected to the surface of the fixing block.

[0010] Preferably, a third extension rod is fixedly connected to the surface of the roller, and a limit rod is fixedly connected to the surface of the third extension rod.

[0011] Preferably, a turntable is fixedly connected to one end of the third extension rod, and a second rotating shaft is fixedly connected to the surface of the turntable.

[0012] Preferably, a second support frame is fixedly connected to one end of the second rotating shaft, and the second support frame has the same structure as the first support frame.

[0013] The technical effects and advantages of this utility model are as follows: 1. This utility model achieves automatic and stable tension adjustment through an improved adjustment component and mechanical feedback structure. Its core lies in the synergistic effect of the swing mechanism composed of the threader, the first extension rod, and the rotating wheel, and the spring: when the tension of the wire increases, the tension will pull the threader, causing the rotating wheel to rotate against the spring tension, thereby reducing the braking on the wire spool through mechanical linkage. When the tension decreases, the spring's rebound force will push the rotating wheel to rotate in the opposite direction, increasing the braking effect. This purely mechanical closed-loop feedback does not require external power or complex sensors, and can offset tension fluctuations caused by changes in speed or inertia in real time. The structure is simple and reliable, with low maintenance costs, and can effectively ensure constant tension of the wire during the unwinding process, preventing stretching deformation due to excessive tightness or disorder due to excessive looseness. 2. This utility model, through an improved rotating component, adopts a sliding fit between the roller and the rotating groove, providing stable radial support for the roller and the entire pay-off reel, greatly reducing the risk of swaying and vibration during high-speed rotation. The combination of the third extension rod, the limiting rod, and the turntable ensures the stability of the reel installation and can be adapted to different specifications of reel drums. This structure makes the pay-off process smooth and with low resistance, effectively protecting the wire surface from scratches and reducing unexpected wire breakage and downtime caused by vibration, thereby ensuring the efficiency and consistency of long-term continuous production.

Detailed Implementation

[0016] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0017] Example 1 Please see Figures 1-5 This utility model is a wire feeding frame with automatic tension adjustment function, including a first support frame 1, a support platform 2 fixedly connected to the surface of the first support frame 1, an adjustment component provided on the surface of the support platform 2, the adjustment component including a fixing block 3 fixedly connected to the top of the support platform 2, a support column 4 fixedly connected to the top of the support platform 2, and a first rotating shaft 5 rotatably connected to the inner cavity of the support column 4. The adjustment component is used to automatically adjust the surface tension of the wire being fed out. A rotating component is provided in the inner cavity of the first support frame 1, the rotating component including a rotating groove 6 opened in the inner cavity of the first support frame 1, a roller 7 slidably connected to the inner cavity of the rotating groove 6, and a roller 8 rotatably connected to the inner cavity of the roller 7. The rotating component is used to complete the wire feeding operation.

[0018] Specifically: support platform 2 is used to place adjustment components, fixing block 3 is used to connect to one end of spring 13 to generate tension, support column 4 is used to provide support for first rotating shaft 5, and rotating groove 6 is used to provide a movement space for roller 7, while limiting it so that it can only run within a predetermined trajectory.

[0019] Example 2 Please see Figures 1-5Based on Embodiment 1, a rotating wheel 9 is fixedly connected to the surface of the first rotating shaft 5, a first extension rod 10 is fixedly connected to the surface of the rotating wheel 9, a second extension rod 11 is fixedly connected to the surface of the rotating wheel 9, a threader 12 is fixedly connected to one end of the first extension rod 10, a spring 13 is fixedly connected to the bottom of the second extension rod 11, one end of the spring 13 is fixedly connected to the surface of the fixing block 3, a third extension rod 14 is fixedly connected to the surface of the roller 8, a limit rod 15 is fixedly connected to the surface of the third extension rod 14, a turntable 16 is fixedly connected to one end of the third extension rod 14, a second rotating shaft 17 is fixedly connected to the surface of the turntable 16, and a second support frame 18 is fixedly connected to one end of the second rotating shaft 17. The second support frame 18 has the same structure as the first support frame 1.

[0020] Specifically: the rotating wheel 9 is used to adjust the angle of the wire threader 12 after it is pulled online, in the direction of the force. The second extension rod 11 is connected to one end of the spring 13 so that after the angle of the rotating wheel 9 changes, the spring 13 pulls the second extension rod 11 to generate a force in the opposite direction, thereby maintaining the tension on the surface of the wire constant. The third extension rod 14 is used to connect the roller 8 and the turntable 16. The limiting rod 15 is used to make the equipment more stable when rotating. The turntable 16 is connected to the second rotating shaft 17 for wire feeding.

[0021] Working principle: When the user needs to perform wire feeding, first, the wire spool is placed on the second rotating shaft 17, and the wire end is passed through the wire feeder 12. During wire feeding, the tension of the wire acts on the wire feeder 12. When the tension increases, it pulls the first extension rod 10, causing the rotating wheel 9 to rotate around the first rotating shaft 5 against the tension of the spring 13. This movement reduces the braking effect on the roller 8 through mechanical linkage, thus making wire feeding smoother and the tension decreases accordingly. When the tension decreases, the restoring force of the spring 13 pushes the rotating wheel 9 to rotate in the opposite direction, thereby increasing the braking effect on the roller 8, tightening the wire and increasing the tension. Throughout the process, the roller 7 in the rotating groove 6 slides adaptively to ensure stable support. This purely mechanical feedback system realizes automatic closed-loop adjustment of tension. It can maintain the dynamic balance of wire feeding tension without external power, thus completing the wire feeding work.

[0022] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
