An accurate tension control method and device for a high-speed binding machine

Abstract

The invention discloses a precise high-speed yarn binding machine tension control method and device. The method comprises the following steps that 1, a full plate yarn group is installed on a high-speed yarn binding machine; 2, the starting speed of a take-up spool is set; 3, the yarn binding machine is started, the yarn binding speed is set, the yarn binding speed is lowered, and yarn binding tension measurement is conducted once when a constant value is lowered each time; 4, yarn binding is adjusted, the tension is set, and the yarn binding tension in step 3 is controlled; 5, the yarn binding speed is adjusted from low to high and then from high to low, and the yarn binding tension in the process is measured continuously; 6, yarn lifting speed compensation is adjusted to correct full yarn and shallow yarn linearity, and the yarn binding tension in step 5 is controlled; 7, a shallow plate yarn group is installed on the high-speed yarn binding machine, and the steps from 2 to 6 are repeated. Accordingly, the yarn binding tension can be accurately controlled, and meanwhile the device has the advantages that the yarn binding speed is high, the tension is precise and stable, and a sheath is not prone to damage.

Description

technical field [0001] The invention relates to a tension control method and a device of a yarn binding machine for optical cable production, in particular to an accurate tension control method and a device of a high-speed yarn binding machine. Background technique [0002] Optical cables are mainly composed of several optical fibers, sleeves and various external protective layers. Yarns are generally wound on the surface of the sleeves before being made into cables. Existing tying machines only control the tying tension at a predetermined tying speed. However, the tying speed will fluctuate, and the process of speed-up and speed-down in production, as well as the size of the yarn group, will cause the yarn tension to be unstable and exceed the predetermined range. Therefore, the existing yarn tying tension control method is prone to the occurrence of a batch of sleeves being flattened by the yarn, causing the optical fiber to be stressed and attenuated. At the same time, ...

AI Technical Summary

Problems solved by technology

In addition, in conventional yarn binding, the yarn is directly placed on the sleeve after winding out of the aircraft guide wheel, which will affect the overall tension of the sleeve and make it unstable

Regardless of whether the yarn tension is unstable or the sleeve tension is unstable, it is easy to cause the sleeve to be tied and flattened, resulting in a large attenuation caused by the force on the optical fiber
