Description

Technical Field

[0001] The utility model belongs to the technical field of wire pay-off racks, and specifically relates to a pneumatic tension wire pay-off rack. Background Art

[0002] The stranded wire is wound on the wire pay-off rack. When paying off the wire, a wire taking machine provides a pulling force to uniformly pull the stranded wire out of the wire pay-off rack. In order to ensure the stable speed of paying off the stranded wire, the wire pay-off rack is usually set as a rotatable pay-off disc, so that the stranded wire is always sent out at the same angle. However, when pulling the stranded wire, the taking frequency of the wire taking machine changes with the change of the wire taking machine, and the randomness is relatively large. At the same time, the taking speed of the wire taking machine is constantly changing, so it is relatively easy to break the stranded wire, affecting the quality of the stranded wire. Therefore, there is an urgent need for a device that can stabilize the tension and speed of paying off the stranded wire at present. Summary of the Utility Model

[0003] In order to solve the above technical problems, the utility model provides a pneumatic tension wire pay-off rack, which includes a bottom plate, a stranded wire, a wire pay-off rack, a first guide member, a second guide member, a third guide member and an adjusting rod. The wire pay-off rack, the first guide member, the second guide member and the third guide member are sequentially arranged from left to right on the upper end surface of the bottom plate; the wire pay-off rack includes a pay-off disc, a pay-off shaft and two pay-off plates. The pay-off plates are arranged in parallel on the left side of the bottom plate. The pay-off shaft is perpendicular to the pay-off plates, and both ends of the pay-off shaft are fixedly connected to the corresponding pay-off plates. The pay-off disc includes a disc body and two annular disc surfaces fixedly connected to both ends of the disc body. The disc body is sleeved on the pay-off shaft and is rotatably connected to the pay-off shaft; the first guide member includes a first guide wheel and a first bracket. The lower end of the first bracket is fixedly arranged on the bottom plate, and the upper end of the first bracket is rotatably connected to the first guide wheel through the rotating shaft of the first guide wheel. A rotating shaft one is fixedly arranged on the front side of the lower end of the first bracket. The second guide member includes a second bracket, a second guide wheel and two pneumatic rods. The fixed ends of the pneumatic rods are arranged on the bottom plate, and the moving ends of the pneumatic rods are fixedly connected to the lower end of the second bracket. The upper end of the second bracket is rotatably connected to the second guide wheel through the rotating shaft of the second guide wheel. A rotating shaft two is fixedly arranged on the front side of the lower end of the second bracket. The third guide member includes a third guide wheel and a third bracket. The lower end of the third bracket is fixedly arranged on the bottom plate, and the upper end of the third bracket is rotatably connected to the third guide wheel through the rotating shaft of the third guide wheel; a first rotating hole and a second rotating hole are respectively arranged in the middle and the right end of the adjusting rod. The first rotating hole and the second rotating hole are respectively sleeved on the rotating shaft one and the rotating shaft two and are rotatably connected to the rotating shaft one and the rotating shaft two. The left end of the adjusting rod extends to the lower side of the disc body, and a friction plate is arranged on the upper part of the left end of the adjusting rod.

[0004] Furthermore, the outer diameter of the disc surface is smaller than the distance from the axis of the pay-off shaft to the bottom plate, so as to prevent the pay-off disc from rubbing against the bottom surface when rotating.

[0005] Furthermore, the first guide pulley, the second guide pulley and the third guide pulley are U-shaped wire guide pulleys, which prevent the stranded wire from slipping out, and the second guide pulley is lower than the first guide pulley and the third guide pulley.

[0006] Furthermore, the friction plate is provided with an arc surface that matches the side wall of the disc surface, enabling the friction plate to closely adhere to the side wall of the disc surface.

[0007] Furthermore, a tension tester is provided on the right side of the third guide member for testing the tension of the stranded wire.

[0008] Furthermore, the stranded wire is wound around the wire pay-off reel, and one end of the stranded wire sequentially bypasses the upper part of the first guide pulley, the lower part of the second guide pulley, the upper part of the third guide pulley and the tension tester.

[0009] Furthermore, the pneumatic rod is electrically connected to the tension tester, and the pneumatic rod can automatically adjust the height of the second guide pulley according to the change of the stranded wire tension.

In addition, the adjusting rod and the friction plate not defined in the present utility model both adopt conventional technical means in the art.

[0011] The working principle of the present utility model is that the stranded wire on the wire pay-off reel of this device sequentially bypasses the upper part of the first guide pulley, the lower part of the second guide pulley and the upper part of the third guide pulley, and is connected to the wire taking machine. When the pulling speed of the stranded wire becomes faster, the tension of the stranded wire becomes larger. The pneumatic rod drives the second guide pulley to rise, reducing the wire taking tension. And the left end of the adjusting rod moves downward, making the friction plate away from the disc surface, reducing the friction force of the disc surface, and making the wire pay-off reel rotate more easily, further reducing the tension of the stranded wire. When the pulling speed of the stranded wire becomes slower, the pneumatic rod drives the second guide pulley to descend, increasing the wire taking tension. And the left end of the adjusting rod moves upward, making the friction plate abut against the disc surface, increasing the friction force of the disc surface, and making the wire pay-off reel not easy to rotate, further increasing the tension of the stranded wire.

[0012] The beneficial effect of the present utility model is that the device of this device is simple and the operation is convenient. It can realize the automatic adjustment and control of the tension of the stranded wire during the pulling process of the stranded wire, avoiding the breakage of the stranded wire and affecting the quality of the stranded wire.
