AI Technical Summary

Technical Problem

In existing technologies, oil stains on the hot rail drip from the gap between the hot rail and the door panel under the action of gravity, causing pollution of the work area and personal injury. In addition, the negative pressure source is difficult to completely extract the oil fumes, resulting in the accumulation of oil mist.

Method used

The bottom of the hot rail is designed as a guide section that slopes downward relative to the horizontal plane. Oil stains on the channel and the channel wall flow naturally to the guide section, and are then collected by the guide device and discharged through the guide pipe, changing the dripping position of the oil stains and preventing dripping from gaps.

Benefits of technology

It effectively prevents oil from dripping from the gap between the hot rail and the door panel, reducing pollution to the work area and personal injury, reducing energy waste, and improving production safety and efficiency.

Abstract

The utility model provides a hot rail, a hot box and a false twist texturing machine. The hot rail comprises a rail body, a plurality of channels for heating chemical fibers are formed in the rail body in the length direction of the rail body, and groove walls are formed on the two sides of the channels. At least part of the bottom end, in the length direction, of the rail body is constructed into a guide part inclining downwards relative to the horizontal plane, and the groove channel and the groove wall extend to the guide part along the bottom end, in the length direction, formed by the rail body. According to the hot rail, the hot box and the false twist texturing machine, oil dirt at the bottom end of the hot rail is prevented from dripping from a gap between the hot rail and the door plate.
