Sizing device in double-feeding form for sizing machine

Abstract

The invention discloses a sizing device in a double-feeding form for a sizing machine. The sizing device comprises a slurry tank, a first squeezing roller, a sizing roller and a second squeezing roller which are arranged in the slurry tank in the direction of advancement of yarns from the back to the front, and a guide roller which is located at the rear of the first squeezing roller and above therear of the slurry tank and used for guiding the yarns into the slurry tank; the slurry tank comprises a main slurry tank and a slurry preheating tank which are sequentially arranged in the slurry flow direction in the tank from the back to the front; the bottom of the slurry preheating tank is connected with a circulation pump for conveying the slurry through a slurry transporting pipeline; a slurry outlet of the circulation pump is connected with the slurry transporting pipeline; slurry outlets of the slurry transporting pipeline are respectively connected with an upper slurry transportingpipeline and a lower slurry feeding pipeline; the slurry outlet of the lower slurry feeding pipeline is connected to the rear of the main slurry tank from the bottom of the slurry tank; the slurry outlet of the upper slurry transporting pipeline is connected with an upper slurry feeding pipeline located above the main slurry tank; the upper slurry feeding pipeline is arranged in a slurry accumulation zone formed between the first squeezing roller and the sizing roller in a manner parallel to the axial direction of the sizing roller; and a plurality of slurry outlets are distributed in the longitudinal direction of the upper slurry feeding pipeline.

Description

technical field [0001] The invention relates to sizing machine equipment applied to textile machinery, in particular to a sizing device in the form of double-feeding sizing for the sizing machine. Background technique [0002] In order to improve the weaving performance of warp yarns, sizing is an effective method taken in weaving preparation engineering. That is, the sizing agent with adhesive material as the main body is applied to the warp yarn, which acts on the surface of the warp yarn to a certain depth, and after drying, a sizing structure in which the sizing material and the yarn are integrated is formed. Yarn sizing is completed in the size tank. After the yarn is soaked in the size tank, the excess size is rolled out by the pressure roller to complete the yarn sizing. In order to ensure the flow of the slurry and prevent the pulping of the skin, the size tank has a circulation device, and the slurry flows from the preheated size tank to the main size tank.

AI Technical Summary

Problems solved by technology

Regardless of the type of the size tank, there are two main ways of feeding the main size tank at present. One is that the main size tank has a size feeding pipe, and the size feeding pipe is below the liquid level of the main size tank. This method cannot meet all process forms. sizing device

The second is that there is a spray pipe above the squeeze area between the sizing roller and the first pressure roller to spray the slurry, but the slurry spraying device has defects such as blockage, insufficient slurry output, and upside-down slurry skin
