AI Technical Summary

Technical Problem

In existing fiberglass kiln drawing equipment, yarn cutting and cleaning processes require manual operation, which poses a safety hazard and cannot achieve automated continuous production.

Method used

A cut-free yarn upper head-changing mechanism with an intermediate yarn clamp and circumferential yarn guide is adopted. By arranging a yarn guide mechanism, a yarn clamp mechanism and a yarn pushing mechanism on the upper head-changing seat, automatic guiding, clamping and pushing of the yarn are achieved, avoiding manual cutting.

Benefits of technology

It improves the efficiency and quality of the upper head change, reduces the amount of transitional yarn, realizes unmanned automated production, and improves the overall production performance and economic benefits.

Abstract

The invention relates to the technical field of glass fiber kiln wire drawing equipment, in particular to a yarn-cutting-free upper head changing mechanism with a middle yarn clamping function and a circumferential yarn guiding function and a control method of the yarn-cutting-free upper head changing mechanism. The yarn-cutting-free upper head changing mechanism comprises a machine head, an upper head changing seat, a yarn pushing mechanism, a yarn clamping mechanism and a yarn guiding mechanism; the control method comprises a gas cut-off state and a gas ventilation state. According to the yarn-cutting-free upper head changing mechanism and the control method thereof, the upper head changing efficiency can be effectively improved through middle yarn clamping of the yarn clamping mechanism and / or circumferential yarn guiding of the yarn guiding mechanism, and the number of transition yarns is reduced; and various upper head changing working modes can be provided, and the adaptive capacity of the wire drawing machine is improved.
