Drying device for cotton yarn production

Abstract

The invention discloses a drying device for cotton yarn production, and relates to the field of spinning. The drying device comprises a bottom plate and a box body, wherein the box body is fixedly connected to the upper end of the bottom plate through a plurality of supporting rods, a yarn inlet and a yarn outlet are formed in the left side wall and the right side wall of the box body correspondingly, an extrusion mechanism and a drying mechanism are arranged in the box body, the extrusion mechanism comprises a threaded hole formed in the upper end of the box body in a penetrating mode, and a threaded rod is in threaded connection with the interior of the threaded hole. By arranging the extrusion mechanism, cotton yarn to be dried can be pretreated, the cotton yarn with high liquid content is extruded, and thus later drying time is shortened; by arranging the threaded rod, the clamping force between a pressing roller and a rotating roller can be adjusted; meanwhile, by arranging a spring, the threaded rod can be prevented from loosening, so that the pressing roller keeps downward pressure all the time; and by arranging a flow guide cover and a flow guide plate, disordered hot air generated by a hot-air blower can be treated, and thus the drying efficiency is improved.

Description

technical field [0001] The invention relates to the textile field, in particular to a drying device for cotton yarn production. Background technique [0002] Cotton yarn is a yarn processed from cotton fiber through spinning process, and it is called cotton thread after plying. According to different spinning processes, it can be divided into carded yarn and combed yarn. (1) Carded yarn: It is a yarn spun from cotton fiber through a common spinning system. (2) Combed yarn: It is a yarn spun from cotton fiber through a combed spinning system. Combed yarn is made of high-quality raw materials. The fibers in the yarn are straight and parallel, with less knots, good luster, evenness and high strength. This kind of cotton yarn is mostly used for weaving high-end fabrics. [0003] Cotton yarn needs to be dried after rinsing or dyeing. The existing drying box has a simple structure, and usually directly uses a hot air blower to dry the cotton yarn. Due to the high liquid content...

Problems solved by technology

[0003] Cotton yarn needs to be dried after rinsing or dyeing. The existing drying box has a simple structure, and usually directly uses a hot air blower to dry the cotton yarn. Due to the high liquid content of some cotton yarn, it will cause drying. The drying time is greatly extended, which has a great impact on the drying efficiency. In addition, the wind direction of the hot air generated by the existing hot air blower is not fixed, and the disordered wind direction cannot stably and continuously dry the cotton yarn, which also leads to low drying efficiency. low reason
