Description

TECHNICAL FIELD

[0002] Cotton yarn is a continuous fiber bundle made of cotton as raw material through a spinning process, is a basic material of the textile industry, and is widely used in the fields of clothes, home textiles and industrial cloth. Cotton yarn is called cotton thread after plying. According to different spinning processes, the cotton yarn can be divided into common yarn and combed yarn. 1. Common yarn: the yarn is spun from cotton fibers through a common spinning system. 2. Combed yarn: the yarn is spun from cotton fibers through a combed spinning system. The combed yarn is made of high-quality raw materials, the fibers in the yarn are straight and parallel, the impurities are few, the gloss is good, the evenness is good, and the strength is high. The cotton yarn is mainly used for weaving high-grade fabrics.

[0003] In the cotton yarn processing process, drying treatment can remove excess moisture in the cotton yarn, reduce the risk of mold in the storage and transportation process of the yarn, improve the strength and stability of the yarn, reduce the broken ends and hairiness, and thus improve the quality of the yarn. Therefore, a drying device needs to be used.

[0004] In the related art, a Chinese invention patent document with the publication number CN112556348A discloses a drying machine for cotton yarn processing. The drying machine comprises a bottom plate, four rectangularly distributed support columns are fixed to the bottom outer wall of the bottom plate, a fixed box is fixed to one side of the top outer wall of the bottom plate, an opening is formed in one side of the outer wall of the fixed box, a plurality of drying boxes are fixed to the bottom inner wall of the fixed box at equal distances, an electric sliding rail is fixed to the middle of the bottom inner wall of the drying box, a placement plate is fixed to the top outer wall of the sliding part of the electric sliding rail, and a placing part is fixed to the top outer wall of the placement plate.

[0005] The above scheme can dry the cotton yarn while the water vapor is discharged into the L-shaped fixed pipe through the single exhaust valve, and then the L-shaped fixed pipe discharges the water vapor into the heat collecting box. The heat carried by the water vapor can be absorbed by the plurality of temperature guide plates and transferred to the water tank to heat the water in the water tank. The heat in the entire drying process is fully utilized, and energy is saved. However, the angle between the air outlet of the drying equipment and the cotton yarn is not easy to control during use, so that the hot air cannot be uniformly distributed on the cotton yarn, resulting in uneven drying of the cotton yarn and further affecting the drying efficiency of the cotton yarn.
