[0002] During the wire rope stranding process, a single strand is placed in a wire wheel turntable. The stability of the single strand unwinding tension directly affects the product quality of the wire rope. At the moment when the tubular wire stranding machine starts, the single strand tension changes from static friction to dynamic friction. At this time, the single strand tension will be greater than the preset tension value, resulting in unstable single strand tensions at the same time, and ultimately affecting the product quality. This situation is called poor start-up in the industry. Different types of wire rope products have different lengths of poor start-up. Over the years, the poor start-up has become a significant production cost for enterprises, causing waste of resources. To solve the problem of poor start-up, a simple and practical tension self-adjusting device is needed. Summary of the Utility Model

The tension self-adjusting device includes a tension seat 5, a left swing rod 9, a right swing rod 12, a guide roller shaft 10, a swing roller shaft 14, a guide roller 11, a swing roller 13, a spring 7, and a limit rod 8. The tension seat 5 is fixed on the left swing rod 9, and both ends of the guide roller shaft 10 are fixedly connected to the wire wheel turret 1. The guide roller 11 is installed through a bearing. In the middle of the guide roller shaft 10, the left swing arm 9 and the right swing arm 12 are respectively installed on the guide roller shaft 10 on both sides of the guide roller 11 through bearings, the swing roller shaft 14 is fixed on the upper part of the left swing arm 9 and the right swing arm 12, and the swing roller 13 is installed in the middle of the swing roller shaft 14 through a bearing 15. The upper ends of the left swing arm 9 and the right swing arm 12 are provided with a slide groove 16, one end of the limit rod 8 is fixed on the line wheel rotating frame 1, the spring 7 is sleeved on the limit rod 8, the other end of the limit rod 8 is inserted in the slide groove 16, and the left swing arm 9 and the right swing arm 12 can slide along the limit rod 8, and the other end of the tension chain 3 is fixedly connected to the tensioning seat 5.
[0018] The tension seat 5 is connected to the tension chain 3 via a tension rod 4 , the tension rod 4 is fixedly connected to the tension chain 3 , and the tension rod 4 is fixed to the tension seat 5 by locking with a nut.
[0019] The nut is an eccentric nut 6. The eccentric nut 6 plays a self-locking role through its own gravity.
[0020] The single strand on the single strand I-shaped wheel passes below the guide roller and above the swing roller, and the outlet wheel rotating frame enters the strand combining channel.
[0021] See Figure 1 The single-strand I-shaped wheel 2 is fixed on the line wheel rotating frame 1 and can make a rotational motion; the tension rod 4 is fixed on the tension seat 5 and locked by the eccentric nut 6; the tension chain 3 is fixed on the tension rod 4.
[0022] See Figure 2 The tensioning seat 5 is fixed on the left swing rod 9 and swings with the left swing rod 9; the guide roller 11, the left swing rod 9 and the right swing rod 12 are fixed on the guide roller shaft 10 through the bearing 15 and can make a rotational motion; the guide roller shaft 10 is fixed on the line wheel rotating frame 1, and the swing roller 13 is fixed on the swing roller shaft 14 through the bearing 15 and can make a rotational motion; the swing roller shaft 14 is fixed on the left swing rod 9 and the right swing rod 12, and swings with the left swing rod 9 and the right swing rod 12.
[0023] A slide groove 16 is provided on the left swing rod 9 and the right swing rod 12, and the limit rod 8 is inserted into the slide groove 16, and the left swing rod 9 and the right swing rod 12 slide along the limit rod 8; the spring 7 is sleeved on the limit rod 8, and when the left swing rod 9 and the right swing rod 12 move downward, the spring 7 is compressed.
[0024] The utility model provides a tension self-adjusting device for a tubular rope twisting machine, which solves the problem of poor starting of the tubular rope twisting machine for steel wire ropes.
[0025] The single strand spool 2 is fixed on the line wheel turret 1, and the tension chain 3 gives the single strand spool 2 a certain friction resistance to generate a preset tension value. The single strand 21 on the single strand spool 2 passes under the guide roller 11 and above the swing roller 13, and the outlet wheel turret 1 enters the strand channel 22.
[0026] When the tubular rope twisting machine is started, the tension chain 3 gives static friction to the single-strand I-shaped wheel 2, which slowly changes from static friction to dynamic friction. Since the static friction is greater than the dynamic friction, the starting tension of the single-strand I-shaped wheel 2 will be greater than the preset tension value. The single strand 21 presses the swing roller 13 downward, and the left swing rod 9 and the right swing rod 12 rotate clockwise, and the tension chain 3 will relax a little, reducing the friction resistance between the tension chain 3 and the single-strand I-shaped wheel 2, and finally reducing the starting tension value.
[0027] When the tubular rope twisting machine operates normally, the tension chain 3 gives the single-strand I-shaped wheel 2 a dynamic friction force, and the tension value of the single-strand 21 will decrease. Under the action of the spring force, the spring 7 pushes the swing roller 13 upward, and the left swing rod 9 and the right swing rod 12 rotate counterclockwise, and the tension chain 3 will be tightened, increasing the friction resistance between the tension chain 3 and the single-strand I-shaped wheel 2, and finally reaching the preset tension value.
[0028] When producing steel wire ropes of different specifications, the preset tension values of the single strands 21 are different. If the tension value difference is large, only the spring 7 needs to be replaced.
[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
