Pre-wetting sizing device

Abstract

The invention relates to the field of sizing machine and especially relates to a pre-wetting sizing device. The pre-wetting sizing device comprises a drawing roller, a first immersing roller, a second immersing roller, an extraction roller and a slurry bucket. The slurry bucket comprises an inner wall and an outer wall. A sealed cavity is formed by the inner wall and the outer wall. Two sides of the outer side are provided with a steam inlet and a steam outlet. Multiple ultrasonic oscillators are arranged on the inner wall. One side, away from the slurry bucket, of the drawing roller is provided with a spraying device and a liquid recovery device, both of which are arranged horizontally and correspondingly. The upper part of the drawing roller is provided with an extrusion roller. The drawing roller is almost attached to the extrusion roller. The drawing roller and the extrusion roller are used for extruding superfluous pre-wetting liquid in pre-wetting yarns in order to avoid dilute grout.Slurries in the slurry bucket are heated by high-temperature steam such that dissolved matter in slurries can be fully dissolved. The ultrasonic oscillators drive slurries in the slurry bucket to flow such that dissolved matter of slurries and heat can be kept uniformly distributed for a long time. Sizing efficiency of yearns is increased. The pre-wetting sizing device is simple in structure and high in practicability.

Description

technical field [0001] The invention relates to the field of sizing machine mechanical equipment, in particular to a pre-wet sizing device. Background technique [0002] In the textile process, sizing is a key process, and the sizing rate is an important indicator of sizing quality. Therefore, reasonable control of the quality of the slurry has become one of the key factors to improve the weaving efficiency and the yield of gray fabrics. The traditional sizing method is to directly carry out the sizing process after the warp yarn is unwound from the warp beam. The sizing process uses guide rollers and submerged rollers to guide and position the yarn, so that the yarn is immersed in the size solution, and the size solution penetrates into its interior to complete the sizing. However, when the dry yarn is directly immersed in the size solution, there is still a layer of air layer between the solid-liquid interface, resulting in a limited infiltration degree for direct sizing,...

Problems solved by technology

However, when the dry yarn is directly immersed in the size solution, there is still a layer of air layer between the solid-liquid interface, resulting in a limited infiltration degree for direct sizing, and the size of the sizing device is often large, and a large amount of size inside will usually become dissolved after a period of time. Uneven material distribution, precipitation at the bottom of the slurry or uneven heat distribution will reduce the sizing rate and affect the yield of gray fabrics
