Description

Technical Field

[0001] The present application relates to the field of two-for-one twisting machines, and in particular to a two-for-one twisting machine with a tensioning device. Background Art

[0002] The two-for-one twister is a twisting device, which is essentially a doubling device (multiple strands are combined into one strand). It can achieve two twists in one turn, and the twisting efficiency is doubled compared to traditional twisting equipment. The package capacity is increased, there is no joint for 10,000 meters, the twisting quality is greatly improved, and the lower layer height is particularly suitable for operation. The twisted yarn is drawn from the stationary yarn feeding package, and passes through the hollow spindle rod from the top of the spindle. With one rotation of the spindle rod, the yarn gets a twist, and then the yarn passes through the horizontal hole of the twisting disk at the lower end of the hollow spindle rod and is led to the yarn collector above.

[0003] In the related art, reference can be made to the Chinese invention patent with authorization announcement number CN102383226B, which discloses a two-for-one twisting machine, including a frame, an upper mounting platform, a middle mounting platform, a lower mounting platform, and a transition device for preventing the single wire from being scratched and broken. The transition device effectively prevents the single wire from being scratched and broken by the middle mounting platform, thereby ensuring the strength of the strands, reducing the probability of production failures, and improving work efficiency.

[0004] When the two-for-one twister is used, the tension of different yarns needs to be adjusted. Too much tension will cause the yarn to break, and too little tension will cause the yarn to loosen. The above-mentioned two-for-one twister is difficult to adjust the tension of the yarn, and the two-for-one twisting effect of the yarn is not good. Utility Model Content
