a sizing machine

Abstract

The invention discloses a starching machine. The starching machine comprises a slurry trough, an immersing roller, a starching roller, a squeezing roller and a feeding mechanism, wherein the feeding mechanism is used for conveying warp yarns; slurry nozzles are respectively positioned in front of the immersing roller, between the immersing roller and the starching roller and at the rear of the starching roller; the slurry nozzles are arranged on one side of the slurry trough, are parallel to the starching roller and are sequentially connected with a first pump and a slurry box through pipes; an opening which is parallel and level to a slurry liquid surface is formed in the rear of the slurry trough; a slurry collecting trough is arranged below the opening and is connected with the slurry box through a pipeline; and an electromagnetic valve and a second pump are arranged on the pipeline for connecting the slurry collecting trough and the slurry box. Slurry is supplemented for the slurry trough through the slurry nozzles, slurry foams are generated nearby the starching roller and the immersing roller, slurry flow sprayed out through the slurry nozzles is guided to flow out along gaps between the immersing roller and the side wall of the slurry trough and between the starching roller and the side wall of the slurry trough, and the circumstance that the slurry flow sprayed out through the slurry nozzles is guided in space between the squeezing roller and the starching roller and is squeezed is avoided basically.

Description

technical field [0001] The invention relates to the field of textile equipment, more specifically, to a sizing machine. Background technique [0002] The traditional warp sizing is to use the yarn in the sizing tank filled with sizing, and through the soaking and sizing action of the immersion roller, sizing roller and sizing roller, so that part of the sizing solution is wrapped on the surface of the yarn and part of it is soaked into the interior of the yarn. Sizing effect. figure 1 In the shown sizing device, the yarn is conveyed to the submerged roller 3 by the feed roller 1 and the guide roller 2 arranged on one side of the size tank 4, and is introduced into the slurry by the submerged roller 3 to absorb the slurry, and the yarn adsorbed with the slurry is then introduced into Pressing is carried out between the squeeze roll 6 and the size roll 5 . [0003] With the above structure, when the immersion roller 3 and the sizing roller 5 immersed in the sizing liquid are...

AI Technical Summary

Problems solved by technology

[0003] With the above structure, when the immersion roller 3 and the sizing roller 5 immersed in the sizing liquid are rotating at a high speed, the sizing liquid is easily scattered or stirred to generate a large amount of air bubbles floating on the surface of the sizing liquid, and the warp yarns are in contact with the above-mentioned air bubbles, so that the uneven sizing material seriously affects the warp yarns. quality

In addition, the shedding and impurities attached to the surface of the warp yarn before sizing are gradually squeezed or dropped into the size solution in the size tank during the sizing process, which pollutes the size solution and affects the quality of the size solution.

To sum up, with the warp yarn sizing process, the quality of the sizing liquid itself is reduced and accompanied by the air bubbles generated during the sizing process, it is difficult to reliably guarantee the quality of the sizing
