Abstract

The utility model discloses a yarn tensioning structure of a yarn elasticizer, relates to the technical field of yarn tensioning, and aims to solve the problems that the range of tensioning force required by yarns of different types and specifications in the elasticizing process is large in difference, and in the running process of the elasticizer, due to factors such as yarn speed change, non-uniformity in the yarn winding process and the like, the tension of the yarns is poor. Yarn tension is easy to fluctuate, when a single-elastic-coefficient spring of an existing yarn tensioning mechanism is used for coping with different tension conditions, especially when the tension change range is large, the situation of excessive compression or stretching possibly occurs, fatigue damage of the spring is easily caused by multiple times of contraction, and once the spring loses efficacy, the yarn tension is prone to fluctuating. In order to solve the problems that in the prior art, due to the fact that the whole tensioning mechanism loses the tensioning effect, the whole tensioning mechanism is directly detached and replaced, and cost is high, the two sets of springs with different elastic coefficients are arranged, tensioning force of different magnitudes can be conveniently shared, each set of springs can be independently detached and replaced, and maintenance cost can be conveniently reduced.

Description

Technical Field

[0001] This utility model relates to the field of yarn tensioning technology, specifically to a yarn tensioning structure for a yarn texturing machine. Background Technology

[0002] During yarn texturing, each processing step (such as stretching and false twisting) places certain requirements on yarn tension. Without a tensioning mechanism, yarn tension may fluctuate during operation due to factors such as speed changes, uneven yarn winding, and variations in the distance between yarn guide components. For example, during the conveying of the yarn from the unwinding bobbin to the texturing area, slight changes in the path may cause it to become too loose or too tight. A tensioning mechanism can stabilize yarn tension by providing appropriate resistance, ensuring that the yarn maintains a stable stress state throughout the texturing process and that each texturing step is performed accurately.

[0003] Chinese Patent 202320006290.5 discloses a yarn tensioning mechanism for a textile texturing machine, belonging to the field of textile technology. It includes a base with two symmetrically fixed plates on its upper surface. Dust removal components are installed on the upper surfaces of both fixed plates, located between two conductor structures. This yarn tensioning mechanism for a textile texturing machine, through the inclusion of an elastic tensioning structure, a switch, and an alarm light, allows for adjustment of the tension by sliding the adjusting sleeve up and down on the support plate surface, based on the tensile strength of different yarns to meet specific needs. The yarn is threaded and transmitted through a tensioning wheel, and the elastic force of the spring provides tension. When the yarn is too tight, a contact block moves downwards to activate the switch; conversely, moving upwards triggers the alarm light, providing an alarm indication when the yarn is too tight or too loose.

[0004] Different types and specifications of yarn require significantly different tension ranges during texturing. Furthermore, during the operation of the texturing machine, yarn tension is prone to fluctuations due to factors such as changes in yarn speed and unevenness during yarn winding. Existing yarn tensioning mechanisms rely on a single elastic coefficient spring, which may over-compress or over-stretch when dealing with different tension conditions, especially when the tension range is large. Repeated contraction can easily cause spring fatigue and damage. Once the spring fails, the entire tensioning mechanism loses its tensioning function, requiring direct disassembly and replacement of the entire tensioning mechanism, which is costly.

[0005] To address the aforementioned issues, a yarn tensioning structure for a yarn texturing machine is proposed. Utility Model Content

One end of the reset spring 303 is fixedly connected to the dismounting clamping plate 301, and the other end of the reset spring 303 is fixedly connected to a limiting pin 304. The limiting pin 304 is slidingly penetrated into the inside of a limiting insertion port 306, and the limiting insertion port 306 is formed on the side of the dismounting clamping ring 305. There are two limiting insertion ports 306 symmetrically arranged about the vertical central axis of the dismounting clamping ring 305.

The outer end of the limiting pin 304 is in the shape of a hemisphere.

[0026] The yarn is passed through the wire passing ring 1, and the yarn moves up and down with the wire passing ring 1 in the sliding process. The spring mechanism below is used to adjust the tension of the yarn. The primary spring 4 has a small elastic coefficient and is easily stretched, which is used to buffer and adjust the small tension change. When the tension is too large, the secondary spring 5 with a large elastic coefficient will also be stretched under force to assist in adjusting the tension.

[0027] When the tensioning mechanism is used for a long time and the spring therein is damaged, the limit pin 304 can be pressed inward to disengage the limit pin 304 from the limit socket 306, and then the disassembly clamping plate 301 can be separated from the disassembly clamping ring 305, the disassembly clamping plate 301 corresponding to the two ends of the spring is separated from the disassembly clamping ring 305, and then the corresponding spring can be removed for replacement.

[0028] The utility model discloses setting two groups of springs with different elastic coefficients, and different elastic sections of the sectional elastic coefficient spring can cooperate with each other, which buffers tension changes caused by external factors to a certain extent, facilitates tension adjustment of different ranges, provides more stable tensioning environment through the sectional elastic coefficient spring, can keep yarn uniform stress state during elasticizing, is favorable for consistency of elasticizing operation such as yarn stretching and curling, and further improves yarn quality and evenness, and the sectional elastic coefficient spring can share different stresses according to stress conditions, the part with smaller elastic coefficient is mainly stressed when yarn tension is smaller, other elastic sections participate in stress when tension is larger, which can optimize stress distribution in the spring, delays fatigue process of the spring, prolongs service life of the spring, reduces maintenance cost, and through the spring dismounting assembly 3 arranged at both ends of the spring, each spring can be individually dismounted from the tensioning mechanism, and then only the spring is dismounted and replaced when the spring is damaged, and the remaining part of the tensioning mechanism can still be used, which facilitates reduction of maintenance cost.
