Machine of pressing yarn for cheese yarn on cones

Abstract

A Cheese pressure consists of motor, oval rotary disc, top pressing basin, lifting bar, link and bottom pressing basin. The presser has double functions of pressing and chamfering and can eliminate inner, middle and outer layer colour difference caused by unevenness of cylinder density in existing loose cylinder dyeing process.

Description

technical field [0001] The invention relates to a cheese pressing device. It is especially used for the pressing device of loose package yarn in the yarn package dyeing process. Background technique [0002] When dyeing yarn packages, uniform density is very important. As the dye solution circulates through the yarn layer, it will encounter resistance from the yarn. Obviously, where the density is high, the resistance will be greater, and the penetration of the dye solution will be small. Then there will be less dyeing on the dye, otherwise more dyeing on the dye, which will cause color difference, and seriously will cause "white marks" (often produced at the "overlapped" winding place of the bobbin). Therefore, the density of the bobbin is required to be uniform everywhere. The uniformity of package dyeing depends largely on the quality of loose tubes, and most of the machines we use are domestic loose tube machines. When the loose tube is formed, it is easy to cause the ...

AI Technical Summary

Problems solved by technology

These are due to poor circulation of the dye solution due to inconsistent density

Some places are short-circuited, some places are open-circuited, and the chances of contact between the dyeing liquid and the yarn are different. Due to the poor uniformity of the forming density, it is required to pick one by one during the bobbin inspection.

Resulting in low efficiency and lower authenticity rate
