[0032] The wheel damping mechanism 4 includes a fixed rod 41, a friction cover 42, a damping block 43, a damping cover 44 and a first guide wheel 45. The fixed rod 41 is parallel to the pay-off shaft 2, the fixed rod 41 is fixedly arranged on the bottom plate 1, the first guide wheel 45 is coaxially mounted on the fixed rod 41 through a bearing 46, the friction cover 42, the damping block 43, and the damping cover 44 are all movably sleeved on the fixed rod 41, the friction cover 42, the damping block 43, the damping cover 44 and the first guide wheel 45 are tightly attached in sequence, and an adjustment unit 47 is arranged on the fixed rod 41, and the adjustment unit 47 is used to adjust the pressing force applied by the friction cover 42 to the damping block 43 along the length direction of the fixed rod 41;

[0033] The adjustment unit 47 includes a pressure cover 471, which is located on a side of the friction cover 42 away from the damping block 43. A disc spring 472 is provided between the pressure cover 471 and the friction cover 42. Both ends of the disc spring 472 are connected to the pressure cover 471 and the friction cover 42 respectively. The pressure cover 471 and the disc spring 472 are both movably sleeved on the fixing rod 41. An adjusting nut 473 is provided on a side of the pressure cover 471 away from the first guide wheel 45. The adjusting nut 473 is threadedly connected to the fixing rod 41, and the adjusting nut 473 abuts against the pressure cover 471.

[0034] A first flange 48 is provided on one side of the damping cover 44 away from the first guide wheel 45. The cavity inside the first flange 48 forms a first placement cavity. The damping block 43 is located in the first placement cavity.

[0035] A second flange 474 is provided on one side of the pressure cover 471 close to the first guide wheel 45. The second flange 474 has a hollow space inside to form a second placement cavity. The disc spring 472 is located in the second placement cavity.

[0036] The friction cover 42 is located in the first placement cavity and the second placement cavity on both sides along the length direction of the fixing rod 41 respectively;

[0037] Working principle of the wheel damping mechanism 4: During normal operation, the steel wire bypasses the first guide wheel 45, and the disc spring 472 is in a compressed state. By rotating the adjusting nut 473, the adjusting nut 473 is moved on the fixing rod 41 along the length direction of the fixing rod 41, thereby adjusting the compression amount of the pressure cover 471 on the disc spring 472, that is, adjusting the pressing force of the disc spring 472 on the friction cover 42, that is, adjusting the pressing force between the damping block 43, the damping cover 44 and the first guide wheel 45. During the twisting process of the steel wire, the steel wire bypasses the first guide wheel 45 and drives the first guide wheel 45 to rotate. The resistance to the rotation of the first guide wheel 45 is adjusted by adjusting the pressing force between the damping cover 44 and the first guide wheel 45, and the resistance to the rotation of the first guide wheel 45 forms the tension of the steel wire;

[0038] The chain damping mechanism 3 includes a friction disc 31, a damping chain 32, a connecting chain 33, a rotating seat 34, a swing arm 35, a connecting rod 36, a spring 37, a first adjusting unit 38 and a second adjusting unit 39. The friction disc 31 is coaxially fixedly mounted on the pay-off shaft 2. One end of the damping chain 32 is connected to the first adjusting unit 38. The other end of the damping chain 32 is connected to one end of the connecting chain 33 after bypassing the outer peripheral wall of the friction disc 31. The other end of the connecting chain 33 is connected to the connecting rod 36. The connecting rod 36 is fixedly arranged on the swing arm 35. The swing arm 35 is fixedly arranged on the rotating seat 34. The rotating seat 34 is rotatably connected to the base plate 1. The second guide wheel 30 is installed on the swing arm 35. One end of the spring 37 is connected to the rotating seat 34. The other end of the spring 37 is connected to the second adjusting unit 39. The steel wire is pulled to travel. During the process, the steel wire passes around the second guide wheel 30, and the movement of the steel wire drives the I-shaped wheel to rotate, and the rotation of the I-shaped wheel drives the pay-off shaft 2 and the friction disk 31 to rotate synchronously. At this time, the friction force between the damping chain 32 and the friction disk 31 generates resistance, and the generated resistance forms the tension of the steel wire on the I-shaped wheel. During this period, the friction force between the damping chain 32 and the friction disk 31 can be adjusted by the first adjusting unit 38 to adjust the tension of the I-shaped wheel steel wire on the pay-off shaft 2. Of course, the tension of the I-shaped wheel steel wire on the pay-off shaft 2 can also be adjusted by adjusting the tightness of the spring 37 by the second adjusting unit 39. When adjusting the tightness of the spring 37, the rotating seat 34 is pulled to rotate by the elastic action of the spring 37. The rotation of the rotating seat 34 tightens or loosens the connecting chain 33 through the connecting rod 36, that is, the function of adjusting the friction force between the damping chain 32 and the friction disk 31 is realized.

[0039] The first adjusting unit 38 comprises a first connecting block 381, a first screw rod 382 and a first fixing block 383. The first fixing block 383 is fixedly arranged on the bottom plate 1. The first screw rod 382 passes through the first fixing block 383. The first screw rod 382 is threadedly connected with the first fixing block 383. The first connecting block 381 is rotatably connected with the first screw rod 382. The first connecting block 381 is fixedly arranged at one end of the damping chain 32. The first screw rod 382 is rotated and moves on the first fixing block 383. The movement of the first screw rod 382 drives one end of the damping chain 32 to move through the movement of the first connecting block 381, that is, the function of adjusting the friction force between the damping chain 32 and the friction disk 31 is realized.

[0040] The second adjusting unit 39 includes a second connecting block 391, a second screw 392 and a second fixing block 393. The second fixing block 393 is fixedly arranged on the bottom plate 1. The second screw 392 passes through the second fixing block 393. The second screw 392 is threadedly connected to the second fixing block 393. The second connecting block 391 is fixedly connected to the second screw 392 for rotation. The second connecting block 391 is fixedly arranged at one end of the spring 37. The second screw 392 is rotated and moves on the second fixing block 393. The movement of the second screw 392 realizes the tightening or loosening of the spring 37 through the second connecting block 391.

[0041] In summary, the combination of chain damping and wheel damping enables the pay-off end to provide the required tension continuously and stably during the production process, which improves the tension stability, ensures the process stability and yield rate of the finished product, and the tension adjustment is convenient and reliable.
