AI Technical Summary

Technical Problem

The existing hot air circulating nylon yarn heat setting device has an unadjustable setting chamber length, resulting in low production flexibility and easy problems of over-setting or under-setting, which affect setting quality and production efficiency.

Method used

Through the coordinated operation of the shaping mechanism, tensioning mechanism, and preheating mechanism, the length of the shaping cavity can be flexibly adjusted. The flattening tension of the nylon yarn and the hot air coverage range are optimized by combining the adjustment component and the extrusion component. The preheating mechanism reduces thermal shock, and the degreasing component ensures clean hot air circulation.

Benefits of technology

It significantly improves the quality of finalization and production flexibility, avoids over-finalization or under-finalization, and ensures the finalization effect in efficient continuous production.
