Abstract
Description
Technical Field
[0001] This utility model relates to the field of yarn quality testing technology, and in particular to a yarn quality testing device. Background Technology
[0002] As a fundamental raw material in the textile industry, the quality of yarn directly determines the quality, performance, and market competitiveness of the final textiles. From everyday clothing to high-end functional fabrics, from home textiles to industrial textiles, every stage relies heavily on high-quality yarn. In garment manufacturing, fabrics made from high-quality yarn are soft to the touch, vibrant in color, comfortable to wear, and durable. In industrial fields, such as aerospace and automotive interiors, the high strength and stability of yarn are crucial to product safety and reliability. Therefore, ensuring that yarn quality meets standards and usage requirements is key to the smooth operation of the textile supply chain and the sustainable development of enterprises. Tensile strength is one of the core indicators for measuring yarn quality, reflecting the maximum stress value that yarn can withstand when stretched by external forces. Higher tensile strength means that the fibers within the yarn are tightly bonded and orderly arranged, possessing good toughness and resistance to damage. This allows the yarn to resist various external forces without breaking during subsequent weaving, dyeing, and other processing, as well as during the final use of the product, ensuring the integrity and durability of the product.
[0003] Traditional methods for testing yarn tensile strength often rely on manual operation. Using simple tensile testing equipment, operators manually apply tension and observe the scale readings at the point of yarn breakage to determine the tensile strength. This method is highly susceptible to human error; differences in operator technique, speed of force application, and force control lead to significant errors in the measurement results, making it difficult to guarantee the accuracy and consistency of the test data. Therefore, a yarn quality testing device is proposed. Utility Model Content

These methods involve using simple tensile testing equipment, where an operator manually applies tension and observes the scale reading at yarn breakage to determine tensile strength. This method is greatly affected by human factors; differences in operating techniques, force application speed, and force control among different operators lead to significant errors in the measurement results, making it difficult to guarantee the accuracy and consistency of the test data.

[0014] (III) Beneficial Effects
[0015] This utility model provides a yarn quality testing device, which has the following beneficial effects:
[0016] 1. This yarn quality testing device, through the setting of the drive mechanism, when in use, takes a portion of yarn and places it in the placement groove on the surface of the carrier plate, and fixes it on both sides with the lower pressure pads. Then, the drive motor at the top is started, and the drive motor drives the lead screw at the end to rotate, realizing the height adjustment of the carrier plate. During the movement of the carrier plate, it will stretch the two tension gauges at the bottom and the yarn on both sides. When the yarn breaks, the tension gauge sends the maximum tensile force of the yarn to the PLC controller on one side for display, thereby realizing accurate measurement of the yarn tensile strength. Compared with the traditional manual measurement, it is more convenient and accurate.
[0017] 2. This yarn quality inspection device, through the clamping mechanism, hydraulic rods, and moving plate, allows for the adjustment of the distance between the two lower pressure pads when inspecting a portion of the yarn due to differences in the sampled yarn length. The hydraulic rods on both sides of the worktable can be activated, which in turn moves the moving plate at the end of the hydraulic rod, thus enabling the installation and fixing of yarns of different lengths. This improves the flexibility of the equipment. Attached Figure Description
