Yarn pressing device used for auxiliary drying

Abstract

The invention belongs to the technical field of cone yarn drying, and particularly relates to a yarn pressing device used for auxiliary drying. The yarn pressing device comprises yarn pressing flow-guiding heads in a drying furnace and driving components for driving the yarn pressing flow-guiding heads to move vertically in the drying furnace, a yarn shaft containing portion is arranged on each yarn pressing flow-guiding head, wherein a yarn shaft located below each yarn pressing flow-guiding head extends into the corresponding yarn shaft containing portion after the yarn pressing flow-guidinghead moves downwards, and the yarn pressing flow-guiding heads move downwards to press the upper ends of cone yarn installed on the yarn shafts in series and force hot wind guided into the yarn shafts to be guided out radically along the yarn shafts and penetrate through the cone yarn installed on the yarn shafts in series from inside to outside; then the hot wind flowing out from peripheral wallthrough holes of the yarn shafts will not flow out from the upper portions of the yarn shafts in the axial direction of the yarn shafts after being blown into the yarn shafts, it is prevented that most hot wind directly flows out from the upper ends without passing the cone yarn, and therefore drying efficiency is improved. The yarn pressing flow-guiding heads automatically press on a yarn trolley through the driving components, human participation is not needed, and therefore the automation degree is greatly increased.

Description

【Technical field】 [0001] The invention belongs to the technical field of cheese drying, in particular to a yarn pressing device for auxiliary drying. 【Background technique】 [0002] Package yarn is the output product of the winding process of the spinning mill in the textile industry. It is the bobbin that falls from the spinning frame or twisting machine in the previous process. According to the requirements of the subsequent process, the length of the yarn is lengthened and the defects and impurities on the yarn are removed. On the winding machine, it is rewound into a borderless or bordered yarn through a grooved drum or a rapidly reciprocating yarn guide hook, and wound into a certain shape ( Such as conical, but also cylindrical), a larger volume of yarn with a certain winding density. [0003] In the production of cheese, there are also processes such as dyeing, washing, drying, and drying. In the automatic production, the package yarn is installed through the yarn l...
