[0002] A tin-coated copper-clad steel wire pay-off device is an auxiliary device for tin-coated copper-clad steel wire that is used in conjunction with a stranding machine to pay off the wire. Tin-coated copper-clad steel wire pay-off devices can be divided into powered pay-off machines and passive pay-off machines. Powered pay-off machines include gantry-type powered pay-off, box-type powered pay-off, frame-type powered pay-off, end-shaft pay-off, and gantry pay-off.

[0003] The prior art Chinese patent with publication number CN221191030U discloses a wire feeding device for the production of tin-plated copper-clad steel wire. It achieves the tensioning function of copper-clad steel wire by adjusting the height difference between the first roller and the second roller. However, since it is difficult to keep one end of the copper-clad steel wire in a taut state at all times, it always lacks the corresponding tension when feeding or winding, making it difficult to ensure tension between the first roller and the winding roller, resulting in poor performance.

[0004] The purpose of this application is to provide a tensioning device for the production of copper-clad steel wire, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a tensioning device for copper-clad steel wire production, comprising a base and two rotating shafts. Two first upright plates are fixedly installed on the top of the base. Each of the two first upright plates has a lifting groove at its bottom and a rotating hole on its inner side wall. One rotating shaft is rotatably installed within the two rotating holes. Each of the two lifting grooves has a lifting hole on its inner side wall. The other rotating shaft is slidably disposed within the two lifting holes via a lifting mechanism. Extrusion rollers are fixedly sleeved on the outer periphery of each of the two rotating shafts. The two rotating shafts are connected by a transmission mechanism. Two second upright plates are fixedly installed on the top of the base. A tensioning mechanism is provided between the two second upright plates. The tensioning mechanism includes two I-shaped wheels, both of which are movably disposed between the two second upright plates.

[0006] Preferably, the lifting mechanism includes two electric telescopic rods, which are respectively fixedly installed on the top of the two first upright plates. The output ends of the two electric telescopic rods pass through the two lifting slots and are each fixedly connected to a sliding sleeve.

[0007] Preferably, the transmission mechanism includes two splined shafts, each of the two sliding sleeves has a spline groove at its bottom end, the bottom ends of the two splined shafts are rotatably mounted on the top of the base, the top ends of the two splined shafts are slidably mounted in the two spline grooves respectively, and the two splined shafts are connected by a rotating assembly.

[0008] Preferably, a first bevel gear is fixedly sleeved on the outer peripheral walls of both splined shafts and the outer peripheral walls of both sliding sleeves, and a second bevel gear is fixedly sleeved on the outer peripheral walls of both rotating shafts, with the two first bevel gears installed in opposite directions.

[0009] Preferably, the rotating assembly includes two connecting shafts, a transmission cavity is provided in the base, the bottom ends of the two connecting shafts are rotatably mounted on the bottom inner wall of the transmission cavity, the top ends of the two connecting shafts extend to the outside of the transmission cavity and are fixedly connected to the bottom ends of the two splined shafts respectively, a synchronous pulley is fixedly sleeved on the peripheral outer wall of the two connecting shafts, a synchronous belt is meshed on the two synchronous pulleys, a drive motor is fixedly mounted on the bottom of the base, and the output shaft of the drive motor is fixedly connected to the bottom end of one of the connecting shafts.

[0010] Preferably, the tensioning mechanism includes two rotating rods, both of which are movably disposed between the two second upright plates via an elastic component.

[0011] Preferably, two support frames are fixedly installed on the top of the base, and a winding roller is rotatably mounted on both support frames.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] 1. In this utility model, the lifting mechanism driven by an electric telescopic rod can precisely adjust the height of the upper extrusion roller and change the distance between the two extrusion rollers, making it widely adaptable. The splined shaft and sliding sleeve in the transmission mechanism ensure uninterrupted transmission during extrusion roller height adjustment, and the two splined shafts rotate synchronously. Combined with the meshing of the first and second bevel gears installed in opposite directions, this allows the two extrusion rollers to rotate in opposite directions, forming a stable clamping force. Regardless of the diameter of the copper-clad steel wire, it can be stably conveyed, avoiding slippage or jamming, and ensuring the stability and consistency of the wire routing during the processing of copper-clad steel wires of different specifications.

[0014] 2. This utility model can respond to tension changes during the conveying of copper-clad steel wire in real time. The elastic component of the tensioning mechanism plays a key role. When the copper-clad steel wire is slack, the compression spring pushes the lifting block to move the I-shaped wheel downward, automatically tightening the wire. When the tension is too high, the I-shaped wheel is pressed and moves the lifting block upward to compress the spring, buffering and reducing the pressure. Without the need for frequent manual adjustments, the copper-clad steel wire can always maintain a suitable tension, preventing slack from affecting processing accuracy and avoiding excessive tension from damaging the wire, thus improving production efficiency and product quality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Reference Figures 1-4The tensioning device for copper-clad steel wire production shown includes a base 1 and two rotating shafts 12. Two first upright plates 2 are fixedly installed on the top of the base 1. Each of the two first upright plates 2 has a lifting groove at its bottom and a rotating hole on the inner side wall of each lifting groove. One of the rotating shafts 12 is rotatably installed in the two rotating holes. Each of the two lifting grooves has a lifting hole on the inner side wall. The other rotating shaft 12 is slidably installed in the two lifting holes through a lifting mechanism. Each of the two rotating shafts 12 has a pressing roller 3 fixedly sleeved on its outer periphery. The two rotating shafts 12 are connected to each other through a transmission mechanism. Two second upright plates 14 are fixedly installed on the top of the base 1. A tensioning mechanism is provided between the two second upright plates 14. The tensioning mechanism includes two I-shaped wheels 19, which are movably arranged between the two second upright plates 14.

[0023] With the above structure, during use, the distance between the two extrusion rollers 3 is adjusted according to the diameter of the copper wire via a lifting mechanism. Then, a transmission mechanism drives the two rotating shafts 12 and the two extrusion rollers 3 to rotate synchronously in opposite directions, thereby causing the two extrusion rollers 3 to rotate in opposite directions to transport the copper wire. The copper wire winds around the two I-shaped wheels 19. If it becomes slack, the tensioning mechanism moves the two I-shaped wheels 19 to tighten the copper-clad steel wire, thus achieving an adaptive tension adjustment function for the copper-clad steel wire.

[0024] like Figure 2 and Figure 3 As shown, the lifting mechanism includes two electric telescopic rods 10, which are fixedly installed on the top of the two first upright plates 2 respectively. The output ends of the two electric telescopic rods 10 pass through the two lifting slots and are fixedly connected to the sliding sleeves 9 respectively. The outer walls of the two sliding sleeves 9 are fixedly fitted with L-shaped plates 21, and one of the rotating shafts 12 is rotatably connected to the two L-shaped plates 21 respectively.

[0025] With the above structure, the height of the upper extrusion roller 3 can be flexibly adjusted via the lifting mechanism, thereby changing the distance between the two extrusion rollers 3 to accommodate copper-clad steel wires of different diameters. When the copper-clad steel wire passes between the two extrusion rollers 3, the transmission mechanism drives the two rotating shafts 12 to rotate synchronously, so that the two extrusion rollers 3 form a stable clamping and conveying effect on the copper-clad steel wire. At the same time, the subsequent tensioning mechanism can adjust the tension of the copper-clad steel wire through the two I-shaped wheels 19 to ensure that the copper-clad steel wire maintains a suitable tension during the production and conveying process, avoiding problems of slackness or excessive tightness.

[0026] like Figure 2 and Figure 3 As shown, the transmission mechanism includes two splined shafts 4, and the bottom ends of the two sliding sleeves 9 are provided with spline grooves. The bottom ends of the two splined shafts 4 are rotatably mounted on the top of the base 1, and the top ends of the two splined shafts 4 are slidably mounted in the two spline grooves respectively. The two splined shafts 4 are connected to each other by a rotating assembly.

[0027] With the above structure, when it is necessary to adjust the distance between the two extrusion rollers 3, the two electric telescopic rods 10 are activated. The output end of the electric telescopic rods 10 drives the sliding sleeve 9 to move up and down in the lifting groove. When the sliding sleeve 9 moves, it drives the rotating shaft 12 connected to it to slide up and down along the lifting hole through the L-shaped plate 21, thereby realizing the height adjustment of the upper extrusion roller 3. This lifting mechanism is easy to operate, has high adjustment accuracy, and can quickly respond to the processing needs of copper-clad steel wire of different specifications. Moreover, the synchronous drive of the two electric telescopic rods 10 can ensure that the force on both ends of the rotating shaft 12 is uniform, avoid tilting and deviation, and ensure that the clamping force of the extrusion roller 3 on the copper-clad steel wire is stable and consistent.

[0028] like Figure 2 and Figure 3 As shown, the outer circumferential walls of the two splined shafts 4 and the outer circumferential walls of the two sliding sleeves 9 are all fixedly fitted with first bevel gears 11, and the outer circumferential walls of the two rotating shafts 12 are all fixedly fitted with second bevel gears 13. The two first bevel gears 11 are installed in opposite directions.

[0029] With the above structure, the splined shaft 4 in the transmission mechanism and the splined groove of the sliding sleeve 9 cooperate to achieve synchronous rotation of the sliding sleeve 9 with the splined shaft 4, and also allow the sliding sleeve 9 to slide up and down axially on the splined shaft 4. Therefore, when the height of the sliding sleeve 9 is adjusted by the lifting mechanism, the transmission effect is not affected. At the same time, the two splined shafts 4 achieve synchronous rotation through the rotating assembly, which ensures that the rotation speed of the two sliding sleeves 9 is the same, thereby ensuring that the rotation speed of the two rotating shafts 12 and the extrusion roller 3 is synchronized. This provides stable and uniform conveying power for the copper-clad steel wire and avoids the copper-clad steel wire from being stretched or jammed due to different conveying speeds on both sides.

[0030] like Figure 2 and Figure 3 As shown, the rotating assembly includes two connecting shafts 5. A transmission cavity is provided inside the base 1. The bottom ends of the two connecting shafts 5 are rotatably mounted on the bottom inner wall of the transmission cavity. The top ends of the two connecting shafts 5 extend to the outside of the transmission cavity and are fixedly connected to the bottom ends of the two splined shafts 4 respectively. Synchronous pulleys 6 are fixedly sleeved on the outer periphery of the two connecting shafts 5. A synchronous belt 7 is meshed on the two synchronous pulleys 6. A drive motor 8 is fixedly mounted on the bottom of the base 1. The output shaft of the drive motor 8 is fixedly connected to the bottom end of one of the connecting shafts 5.

[0031] With the above structure, when the drive motor 8 is started, its output shaft will drive the connecting shaft 5 connected to it to rotate. The connecting shaft 5 drives another connecting shaft 5 to rotate synchronously through the transmission action of the synchronous pulley 6 and the synchronous belt 7. The two connecting shafts 5 then drive the spline shaft 4 at the top to rotate, realizing the synchronous drive of the two spline shafts 4. The synchronous belt drive method has high transmission efficiency, low noise, and accurate transmission ratio, which can ensure that the speed of the two spline shafts 4 is completely consistent, providing a reliable power guarantee for the stable conveying of the subsequent extrusion roller 3.

[0032] like Figure 4 As shown, the tensioning mechanism includes two rotating rods 18, both of which are movably mounted between two second vertical plates 14 via elastic components. Two I-shaped wheels 19 are respectively fixedly sleeved on the two rotating rods 18. The elastic components include two lifting blocks 15. The opposite sides of the two second vertical plates 14 are provided with mounting grooves. The opposite inner walls of the two mounting grooves are fixedly mounted with limit shafts 16. The two lifting blocks 15 are respectively slidably mounted on the two limit shafts 16. The outer walls of the two limit shafts 16 are each sleeved with a compression spring 17. The two ends of the rotating rods 18 are respectively rotatably mounted on the opposite sides of the two lifting blocks 15.

[0033] With the above structure, when the tensioning mechanism is working, the copper-clad steel wire passes over the two I-shaped wheels 19. When the copper-clad steel wire becomes slack, the compression spring 17 pushes the lifting block 15 to move downward along the limit shaft 16. The lifting block 15 drives the rotating rod 18 and the I-shaped wheels 19 to move downward, thereby tightening the copper-clad steel wire. When the tension on the copper-clad steel wire is too high, it pushes the I-shaped wheels 19 to move upward, which in turn drives the rotating rod 18 and the lifting block 15 to slide upward along the limit shaft 16. The compression spring 17 is compressed, playing a role in buffering and reducing pressure. This elastic tensioning structure can automatically adapt to the tension changes of the copper-clad steel wire during the conveying process and adjust the tension in real time without frequent manual intervention. Moreover, the limit shaft 16 can restrict the movement direction of the lifting block 15 to prevent the I-shaped wheels 19 from deviating, ensuring a stable and reliable tensioning process and effectively protecting the copper-clad steel wire from excessive stretching damage.

[0034] like Figure 1 As shown, two support frames are fixedly installed on the top of the base 1, and a winding roller 20 is rotatably mounted on both support frames.

[0035] With the above structure, the winding roller 20 can wind up and store the copper-clad steel wire after extrusion and tensioning, or install the wire coil during unwinding, facilitating subsequent storage, transportation, and further processing. The winding roller 20 is rotatably mounted on top of the base 1 via a support frame. Its positional layout is reasonable and forms a continuous production process with the extrusion and tensioning mechanism in front, reducing path loss of the copper-clad steel wire during transportation and improving production efficiency.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
