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.
