Embodiment 1

[0041] Such as figure 1 As shown, in this example, a total of 21 independently driven drafting rollers 1 are designed, which are arranged in two parallel and staggered rows, including 11 in the upper row and 10 in the lower row, with a roller length of 280mm and a roller diameter of 200mm. The distance between the centers of the two drafting rollers is 400mm, the difference between the lower row of drafting rollers and the upper row of drafting rollers is 200mm, the distance between the center heights of the upper and lower rows of drafting rollers is 1500mm, and the wire inlet is set at the first drafting roller of the upper row , the tow exit is set at the last drafting roller in the upper row.

[0042] The heating plate is divided into upper and lower parts, both of which are rectangular toothed. The teeth of the upper heating plate are downward, and the teeth of the lower heating plate are upward, interlaced with each other. Among them, the upper heating plate has 10 rect...

Abstract

The invention relates to a silk drafting/drying device which comprises at least one pair of matched heat plates used for drying silk flock and a plurality of independently-driven drafting rollers used for drafting the silk flock. The drafting rollers are arranged at the interval position of the matched heat plates, the drafting rollers are of cylinder structures and divided into an upper row of drafting rollers and a lower row of drafting rollers, the two rows of drafting rollers are distributed in parallel and in a staggered mode, the pair of heat plates are the upper heat plate and the lower heat plate, rectangular teeth are arranged on each heat plate, and the rectangular teeth of the upper heat plate are staggered and meshed with the rectangular teeth of the lower heat plate. According to the silk drafting/drying device, a multi-roller drafting machine and a drafting hot box are integrally combined, and the equipment construction cost and the equipment occupancy are reduced. By means of liquid heat media, the defect that caloric content in heated air circulation is low is overcome, the interference to the silk flock is reduced, the temperature is even and stable, the steam concentration is improved, the drafting/drying efficiency and effect are improved, and the recycling load and the energy consumption are effectively reduced. According to need, the silk drafting/dry device can be used for drafting silk, can be used for drying silk and can achieve the purpose of drafting silk in a drying process. Furthermore, a plurality of silk draft/drying devices can be combined to be used.

Description

technical field [0001] The invention relates to the field of chemical fiber equipment, in particular to a device for drawing / drying silk, which integrates the functions of a multi-roller drawing machine and a drawing heating box. Background technique [0002] In the production process of chemical fibers, the drafting and drying of silk are very important links. For example, melt-spun polyester and polypropylene fibers have corresponding drafting processes and equipment; while solution-spun acrylic fibers and viscose fibers require not only drafting , but also related to drying. Compared with conventional fibers, the drafting and drying of high-performance fibers has more stringent requirements on drafting and drying equipment. For example, high-performance polyethylene fibers require a long residence time in the drying process, the equipment is airtight, and the air volume is small so that they can be completely dried and contain solvents. The gas does not leak out, and the...
