Description

Yarn guide ring device suitable for core-spun yarn doubling

Technical Field

The utility model relates to a weaving equipment field specifically indicates a lead yarn circle device suitable for core-spun yarn doubling use.

Background

The yarn guide rings used by doubling machines on the market at present are divided into two types, one type is a closed type yarn guide ring and the other type is an open type yarn guide ring, and operators using the closed type yarn guide ring are very inconvenient to operate when changing yarns and leading wires, so that the efficiency is low; the yarn lead of the yarn ring is changed conveniently by using the open type, the efficiency is high, but when the open type yarn ring is used, the lower cone yarn is placed in the unified direction according to the requirement, the cone yarn unwinding balloon direction is consistent, if the cone yarn is placed in the reverse direction, the cone yarn can run out of the yarn ring in the unwinding process, and therefore the yarn doubling tension consistency is poor, and even the yarn breakage is caused. The high-strength polyester core-spun sewing thread has smooth surface and strong rigidity, the bobbin yarn is easy to have the condition of edge crossing in the process of spinning single yarn (winding process), the edge crossing of the bobbin yarn is usually only arranged on one end surface of the bobbin yarn in general, when the bobbin yarn with the edge crossing is taken out and combined for production, in order to unwind, the side of the bobbin yarn with the edge crossing needs to be upward, when the side of the bobbin yarn with the edge crossing is upward, in order to obtain the quality of yarn, whether the unwinding direction of the yarn is consistent with the direction of the current yarn guide ring needs to be observed, if the yarn is inconsistent, the yarn can run out of the yarn guide ring, and therefore, the direction of the yarn guide ring needs to be adjusted when the yarn is inconsistent. At present, the yarn guide ring on the doubling machine is mostly fixed by screws or bolts, the disassembly and the assembly are very inconvenient, and the difficulty of adjusting the yarn guide ring by an operator according to the condition of cheese is high in the production process.

SUMMERY OF THE UTILITY MODEL
