Adjusting device for yarn tension

Abstract

The invention provides an adjusting device for yarn tension. The adjusting device comprises a rack, a yarn guiding eye and a primary tension disc set, wherein the yarn guiding eye and the primary tension disc set are sequentially arranged on the rack along the winding direction of yarns; the primary tension disc set is provided with an upper tension disc and a lower tension disc which are oppositely arranged; a clearance for allowing the yarns to penetrate through is formed between the upper tension disc and the lower tension disc; a damping ring is arranged below the lower tension disc. The adjusting device is characterized by further comprising a secondary tension disc set arranged at the rear end of the primary tension disc set along the winding direction of the yarns; the secondary tension disc set is also provided with an upper tension disc, a lower tension disc and a pressurizing mechanism; the upper tension disc set and the lower tension disc set are oppositely arranged; the pressurizing mechanism is arranged above the upper tension disc and can be used for adjusting the downward pressure of the upper tension disc. According to the adjusting device for the yarn tension, which is disclosed by the invention, the fluctuation of output tension is relieved by two-time adjustment; meanwhile, flying sundries generated in the threading process can be automatically cleared and normal work of the tension device is ensured. The adjusting device is suitable for high-speed warping.

Description

technical field [0001] The invention relates to a tension device, in particular to a yarn tension adjustment device for a warping machine, which belongs to the technical field of textile machinery. Background technique [0002] There is a tension device on the warping machine to add tension to the yarn, so that the warp beam can be well formed and the winding density is high. The warp tension of the whole piece is uniform. At present, the commonly used tension device is a tension disc device. After the warp yarn exits from the bobbin and passes through the guide eye, it bypasses the porcelain column and passes through the gap between the upper and lower tension discs. The lower tension disc is provided with a shock absorbing ring. The diameter change (that is, when there is a nep) makes the tension plate vibrate up and down, and the shock absorbing ring absorbs the vibration to achieve the purpose of uniform tension. In this method, because of the addition of porcelain pil...

AI Technical Summary

Problems solved by technology

In this method, because of the addition of porcelain pillars, the yarn jumps up and down on the porcelain pillars, and the additional tension of the yarn depends on the wrap angle of the porcelain pillars, which exaggerates the tension fluctuations of the warp yarns, making the output tension fluctuate greatly and encountering yarn defects. When the knot ends, the tension disc will jump, which is not suitable for high-speed warping
