Post-drawing production line for polyester tow

Abstract

The invention discloses a polyester strand back drafting production line which comprises a back drafting device, wherein a rolling device is arranged behind the back drafting device, a drying box is arranged behind the rolling device, a dragging platform is arranged behind the drying box, two dragging rollers are arranged at the tail part of the dragging platform, a strand placing box is arranged under the dragging rollers, a steam spraying device is arranged on the dragging platform, the steam spraying device comprises an upper steam box and a lower steam box, a channel allowing a polyester strand to pass through is arranged between the upper steam box and the lower steam box, an upper through steam hole and a lower through steam hole are respectively formed in the upper steam box and the lower steam box, the upper through steam hole and the lower through steam hole are connected with a steam source through pipelines, the lower surface of the upper steam box is provided with a plurality of first air holes capable of spraying steam to the polyester strand, the upper surface of the lower steam box is provided with a plurality of second air holes capable of spraying steam to the polyester strand, and water discharging holes capable of discharging condensing water are formed in the lower part of the lower steam box. The polyester strand back drafting production line enables the polyester strand to be smooth and soft and is good for following processing.

Description

technical field [0001] The invention relates to textile machinery, in particular to a post-drawing production line of polyester tow. Background technique [0002] The structure of the existing post-drawing production line for polyester tow is as follows: it includes a post-drawing device, a crimping device is installed behind the post-drawing device, a drying box is installed behind the crimping device, and a traction platform is arranged behind the drying box , two traction rollers are installed at the tail of the traction platform, and a collection box is placed under the traction rollers; the processing process of polyester tow in the existing post-drawing production line of polyester tow is: polyester tow is first The drawing is carried out in the drawing device, and then crimping is carried out in the crimping device, and then it is dried and heat-set in the drying box, and finally it is pulled by the traction roller and collected in the yarn collection barrel; after th...

It becomes longer, and the bundle fibers of the tow tend to increase
