Drafting water bath for short fiber stretching production line

Abstract

The invention provides a drafting water bath for a short fiber stretching production line. The drafting water bath comprises a bath body, wherein a front drafting roll and a front stainless steel roll are arranged at the front end of the bath body; a back drafting roll and a back stainless steel roll are arranged at the back end of the bath body; two limiting discs sleeve the front drafting roll, two limiting discs sleeve the back drafting roll, rotary swing arms sleeve the two ends of the front stainless steel roll, a guide roll is connected between the two swing arms, and an arc-shaped groove is formed in the side surface of the bath body and is used for a shaft of the guide roll to penetrate out; an arc-shaped sealing plate is fixedly arranged at the outer side of the arc-shaped groove; the swing arms are abutted against the arc-shaped sealing plate; the end part of each swing arm is provided with a bolt which is locked with the arc-shaped sealing plate. The drafting water bath for the short fiber stretching production line has the advantages that by arranging the guide roll with adjustable height, the short fiber bundles can be switched at different liquid levels; the utilization rate of liquid in the bath body is improved, the frequent replacement of liquid in the bath body is prevented, and the water resource is saved.

Description

technical field [0001] The invention belongs to the technical field of short fiber drawing, and relates to a drawing water bath on a short fiber drawing production line. Background technique [0002] In the short fiber drawing process, the drawing water bath is located between the first drawing machine and the second drawing machine, and its main function is to heat the tow above the glass transition temperature for drawing. A chemical fiber tow drafting water bath disclosed in a Chinese patent includes: a tank body, a heat exchanger, a front drafting roller, a rear drafting roller, a smooth roller, and a wool felt cover. Fixed on one side outside the tank body, the front drafting roller is set on one end inside the tank body through a bearing, the rear drafting roller is set on the other end inside the tank body through a bearing, and the smooth roller is movable on the tank body, smooth The roller is arranged above the rear drafting roller, and the smooth roller is covere...

AI Technical Summary

Problems solved by technology

Since the liquid in the water bath is treated, the impurities in the lower layer are getting thicker and thicker, while the upper layer has more foam, so it is necessary to adjust the height of the short fiber bundles in the water bath, but the current water bath has a high impact on the short fiber bundles in the water bath. height cannot be adjusted
