Novel disk type tension device

Abstract

The invention relates to a textile machine, in particular to an improvement of a novel disk type tension device. The novel disk type tension device comprises a mandrel, an upper tension disk, a lower tension disk and a tension washer. The mandrel is movably sleeved with the upper tension disk, the lower tension disk and the tension washer, the upper tension disk and the lower tension disk are arranged oppositely, the upper tension disk is located over the lower tension disk, the tension washer is located over the upper tension disk, a cocoon cotton polyester fiber washer is installed between the tension washer and the upper tension disk, and the thickness of the cocoon cotton polyester fiber washer ranges between 1mm and 20mm. The novel disk type tension device can absorb bounce energy of the tension disks and bounce energy of the tension washer stably and efficiently for a long time and apply uniform additional tension force to yarn.

Description

Technical field: [0001] The invention relates to a textile machine, in particular to an improvement of a disc tension device. Background technique: [0002] Winding (also known as winding) is one of the processes in the spinning and dyeing process. When winding, the yarn is wound onto the bobbin through a tension device. The performance of the tension device should achieve the following points: (1) The additional tension given to the yarn should be uniform, so as not to expand the relative value of the tension fluctuation range before the yarn enters the tension device; (2) The contact surface with the yarn should be smooth so as not to cause Wool yarn; (3) simple structure, easy to adjust to meet the requirements of different yarn characteristics; (4) not easy to accumulate flying impurities, and easy to clean; (5) has a certain tension automatic compensation function. That is, when the tension fluctuates too much, it can automatically adjust the friction on the yarn and a...

AI Technical Summary

Problems solved by technology

This disc-type tension device can give the yarn a relatively uniform additional tension, but the felt washer is prone to plastic deformation after being subjected to the long-term compression of the tension washer on it and the shock caused by vibration, and makes the felt washer absorb the tension circle. Reduced effect of bouncing energy of discs and tension washers, thus affecting uniformity of yarn tension

At present, the disk-type tension device that can absorb the beating energy of the tension disc and the tension washer in a long-term, stable and efficient manner, and give the yarn a relatively uniform additional tension has not been seen, nor has it been found in materials and media reports
