Yarn traction device

Abstract

The invention provides a yarn traction device which guides high temperature in a heat preservation box to a low temperature air area and thus restrains power consumption of rollers in the lower temperature air area and further reduces the operation cost. The yarn traction device (100) comprising a plurality of rollers (21 and 22) which deliver yarn (Y) through rotation comprises the heat preservation box (23) receiving the rollers (21 and 22), and an air pipe channel (24) installed in the heat preservation box (23), wherein the air pipe channel (24) guides high temperature air in the heat preservation box (23) to a low temperature air area in the heat preservation box (23).

Description

technical field [0001] The present invention relates to the technology of spinning drawing equipment. In more detail, it relates to the technology of the spinning drawing-up facility which can reduce running cost. Background technique [0002] Conventionally, there is known a spinning take-up device provided with a plurality of rollers that feed out a yarn by rotation (for example, Patent Document 1). Such a spinning take-up device includes a roll for heating the yarn to a drawing temperature (hereinafter referred to as “heating roll”) and a roll for heating the yarn to a tempering temperature (hereinafter referred to as “conditioning roll”). [0003] However, there is known a spinning take-up device in which a heating roll and a tempering roll are accommodated in a single thermal box (for example, Patent Document 2). This is to reduce the power consumption of the electric heater built in each roll by storing the heating roll and the tempering roll in the thermal insulatio...

AI Technical Summary

Problems solved by technology

However, when there is a low-temperature air area in the incubator, the power consumption of the rollers placed in the low-temperature air area cannot be suppressed, and there is a problem that the running cost cannot be sufficiently reduced.
