Description

Technical Field

[0001] This utility model relates to the field of wire production technology, and in particular to a wire winding and tensioning device. Background Technology

[0002] Maintaining constant tension is a key factor in ensuring winding quality during the production and winding of wires, cables, and optical fibers. Insufficient tension can lead to loose wires, uneven winding, or even coil collapse; while excessive tension can cause wire stretching and deformation, insulation damage, or wire breakage.

[0003] Traditional wire winding tensioning devices typically employ mechanical tensioning mechanisms, such as spring compression, counterweights, or friction braking, to adjust tension. However, traditional fixed tensioning mechanisms struggle to adapt to variations in wire diameter, material, or winding speed, requiring frequent manual adjustments that impact production efficiency. Furthermore, during high-speed winding or start-stop phases, traditional mechanical structures cannot respond quickly to tension changes, easily leading to uneven wire tension. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing traditional fixed tensioning mechanisms, which are difficult to adapt to changes in wire diameter, material, or winding speed, require frequent manual adjustments, affect production efficiency, and are unable to respond quickly to tension changes during high-speed winding or start-stop phases, easily causing uneven wire tension. Therefore, this invention proposes a wire winding tensioning device.

[0008] Preferably, the tightening mechanism is provided in two sets, the movable frame is slidably connected to the slide rod, and the movable frame is arranged in an H shape.

[0009] Preferably, the slide plate has protrusions on both sides, and the protrusions slide in conjunction with the limiting groove.

[0011] Preferably, the transmission roller is provided with a limit strip, the winding reel is provided with a limit hole, and the extension end of the winding reel is provided with a locking bolt.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. In use, this utility model adopts a servo motor to drive the screw to adjust the position of the moving frame, combined with the guide of the slide bar, to achieve precise and rapid movement of the guide wheel. It can quickly respond to tension changes during high-speed winding or start-stop stages, effectively avoiding the problem of uneven wire tension.

[0014] 2. When in use, this utility model uses a hydraulic cylinder to drive the slide plate and tightening mechanism to lift and lower as a whole.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-4 A wire winding and tensioning device includes a base 1, a fixing plate 2 on the base 1, a limiting groove 3 in the fixing plate 2, a sliding plate 4 slidably disposed in the limiting groove 3, and a tensioning mechanism 5 for tightening the wire on the sliding plate 4. The tensioning mechanism 5 includes a screw 51, a sliding rod 52, a moving frame 53, a guide wheel 54, and a servo motor 55. The screw 51 is rotatably disposed between the sliding plates 4, the sliding rod 52 is fixedly disposed between the sliding plates 4, the moving frame 53 is threadedly connected to the screw 51, the guide wheel 54 is rotatably disposed in the moving frame 53, and the servo motor 55 is fixedly disposed on the sliding plate 4.

[0024] A connecting plate 6 is provided at the bottom of the slide plate 4, and a hydraulic cylinder 7 is provided at the bottom of the connecting plate 6. A winding mechanism 8 for winding up the wire is provided behind the fixed plate 2. The winding mechanism 8 includes a servo motor 10, a transmission roller 11, a winding wheel 12, and a fixed wall 16. The servo motor 10 is fixedly mounted on the fixed wall 16, the transmission roller 11 is rotatably mounted on the side of the fixed wall 16 away from the servo motor 10, the winding wheel 12 is slidably mounted on the transmission roller 11, and the fixed wall 16 is fixedly mounted on the base 1.

[0025] It should be noted that the servo motor 55, hydraulic cylinder 7 and servo motor 10 are all existing technologies in this field. The specific model and specifications to be used need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts existing technologies in this field, so it will not be elaborated here. All of them can be powered by external devices and controlled to turn on and off.

[0026] Furthermore, the tightening mechanism 5 is provided in two sets, with the movable frame 53 slidably connected to the slide rod 52, and the movable frame 53 is arranged in an H shape.

[0027] Among them, a tension sensor is installed on the outside of the guide wheel 54 in the tightening mechanism 5 near the winding mechanism 8. In conjunction with the servo motor 10, the tension of the wire is detected in real time and the winding speed is automatically adjusted.

[0028] Furthermore, protrusions 9 are provided on both sides of the slide plate 4, and the protrusions 9 slide in conjunction with the limiting groove 3.

[0029] Among them, the slide plate 4 slides with the limit groove 3 through the protrusion 9 to ensure the smooth operation of the tightening mechanism 5.

[0030] Furthermore, the transmission roller 11 is provided with a limit bar 13, the winding wheel 12 is provided with a limit hole 14, and the extended end of the winding wheel 12 is provided with a locking bolt 15.

[0031] The winding wheel 12 is locked to the limiting hole 14 by the limiting strip 13 and fixed by the locking bolt 15 to prevent slippage or deviation during winding and to ensure that the wire is wound neatly.

[0032] Working principle:

[0033] First, adjust the position of the winding wheel 12 according to the wire diameter and material of the wire to be wound, so that it slides on the transmission roller 11 to a suitable position, and is positioned by the limit strip 13 and the limit hole 14. Finally, it is fixed with the locking bolt 15 to prevent loosening during winding.

[0034] The wire is led out from the wire feeding device and passed sequentially through the guide wheels 54 of the two sets of tightening mechanisms 5. The servo motor 55 is started, driving the screw 51 to rotate, which in turn causes the moving frame 53 to slide along the slide bar 52, so that the spacing of the guide wheels 54 adapts to the wire tension requirements. Because the moving frame 53 has an H-shaped structure, it ensures that the wire runs stably on the guide wheels 54 and avoids deviation.

[0035] A tension sensor is installed on the outer side of the guide wheel 54 near the winding mechanism 8 to monitor the wire tension in real time. The servo motor 10 is started to drive the transmission roller 11 to rotate, initiating winding. If the tension sensor detects abnormal tension, such as too loose or too tight, the system automatically adjusts the speed of the servo motor 10, or uses the hydraulic cylinder 7 to push the slide plate 4 up and down along the limit groove 3, dynamically adjusting the height of the tightening mechanism 5 to ensure constant tension.

[0036] During high-speed winding or sudden start / stop, the hydraulic cylinder 7 can quickly respond to tension changes and, in conjunction with the servo motor 55, fine-tune the position of the guide wheel 54 to prevent uneven wire tension. At the same time, the protrusions 9 on both sides of the slide plate 4 fit tightly with the limiting grooves 3 to ensure smooth operation of the tightening mechanism 5 and avoid vibration affecting the winding quality.

[0037] Once winding is complete, stop the servo motor 10, loosen the locking bolt 15, and remove the winding reel 12 to replace it with an empty one. If the wire specifications need to be adjusted, simply readjust the spacing of the guide wheels 54 or replace the winding reel 12 with a suitable one; no complicated disassembly or assembly is required, thus improving production efficiency.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
