Novel spring-weighted tension device

Abstract

The invention relates to textile machines, in particular to an improvement of a spring-weighted tension device, and provides a novel spring-weighted tension device. The novel spring-weighted tension device comprises a guide rod, a static tension disk, a dynamic tension disk, a spring and a straining ring, wherein the static tension disk is fixed to the guide rod through a screw; the dynamic tension disk is movably arranged on the guide rod in a sleeved mode and arranged opposite to the static tension disk; the spring and the straining ring are installed on the guide rod in a sleeved mode, wherein the spring is located between the dynamic tension disk and the straining ring and makes contact with the dynamic tension disk, and the straining ring is fixed to the guide rod through a screw; a cocoon cotton-shaped polyester washer is installed between the spring and the dynamic tension disk, wherein the thickness of the cocoon cotton-shaped polyester washer ranges from 1 mm to 20 mm. The novel spring-weighted tension device can absorb vibration energy of the dynamic tension disk stably and efficiently for long, thereby providing quite even additional tension for yarn.

Description

Technical field: [0001] The present invention relates to textile machines, and in particular to improvements in spring-loaded tensioning devices. 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 fricti...

AI Technical Summary

Problems solved by technology

When the yarn passes through quickly, due to the unevenness of the yarn diameter, the dynamic tension disc will produce small vibrations, which will cause intermittent changes in the winding tension, thereby affecting the quality of the winding

At present, the spring-loaded tension device that can absorb the vibration energy of the dynamic tension disc 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
