The influence of yarn guide angle and surface finish of yarn guide plate on yarn winding and its optimization strategy

The key role of yarn guide plate in modern spinning production
In modern textile industry production, Barmag spinning machine is a key equipment for filament production, and the performance of its winding system directly affects the quality and production efficiency of the final product. Barmag Spinning Machine Winder Parts Yarn Guide Plate, as one of the core components of the winding system, undertakes the important functions of guiding the yarn movement trajectory, controlling the yarn tension and ensuring the winding quality. With the continuous improvement of product quality requirements in the textile industry and the widespread application of new fiber materials, the design and manufacturing process of yarn guide plates are facing new challenges and opportunities.

Jiaxing Shengbang Mechanical Equipment Co., Ltd., as a high-tech enterprise specializing in the research and development and production of key parts of spinning machinery, has accumulated rich experience in the research and development and production of yarn guide plates. The company has advanced manufacturing equipment including Schenck dynamic balancing machine, plasma coating equipment, etc., which can provide high-performance yarn guide plate solutions for different models of Barmag spinning machines. Through the precise control of the yarn guide angle and surface finish, the quality problems such as yarn breakage and excessive hairiness in the production process are effectively solved, and the production efficiency and product quality are significantly improved.

Analysis of the influence of yarn guide angle on the depth of yarn winding
The yarn guide angle is the angle between the direction of the yarn movement guided by the yarn guide plate and the winding axis. The design of this parameter needs to comprehensively consider multiple factors such as yarn tension, winding speed and fiber characteristics. From a mechanical point of view, the yarn guide angle directly affects the force of the yarn on the yarn guide plate. Our engineering team simulates and optimizes the yarn guide angle through finite element analysis software to ensure that the optimal yarn tension can be maintained under various working conditions.

In actual production, different yarn varieties have different requirements for yarn guide angles. POY yarn has a higher elongation, so a smaller yarn guide angle is required to reduce the tensile deformation of the yarn; FDY yarn has a higher orientation, so a larger yarn guide angle can be used to increase the winding density; industrial high-strength yarn requires a specially designed yarn guide angle to balance tension and wear resistance. Shengbang Mechanical's multifunctional spinning test machine can systematically test different yarn varieties and provide customers with the optimal yarn guide angle parameters.

The optimization of the yarn guide angle not only affects the quality of the single yarn, but also affects the forming effect of the entire package. Unreasonable yarn guide angles can lead to problems such as package convex edges, package collapse edges and overlapping yarns. Through the precise detection of the Schenck dynamic balancing machine, we ensure that the angle tolerance of each yarn guide plate is controlled within a strict range, which greatly improves the forming quality of the package. Actual cases show that the optimized yarn guide angle can significantly increase the package density and significantly improve the unwinding efficiency.

Fine control technology of surface finish
The surface finish of the Barmag Spinning Machine Winder Parts Yarn Guide Plate is usually expressed in Ra values, which require strict control for high-end spinning applications. We use advanced surface profilers and laser interferometers for testing to ensure that each product meets strict surface quality standards.

Shengbang Mechanical uses a variety of surface treatment technologies to improve the performance of the yarn guide plate. Plasma spraying technology uses advanced equipment to spray ceramic coatings, which significantly improves hardness and reduces friction coefficients. The precision polishing process uses nano-diamond abrasive paste and multi-axis linkage CNC polishing equipment to achieve a mirror effect. Special coating technologies such as diamond-like carbon coating and titanium nitride coating greatly increase the service life. These advanced treatment processes provide the best surface solutions for different yarn production.

The surface characteristics of the yarn guide plate are related to the yarn quality in many aspects. The tribological characteristics affect the tension stability of the yarn, the surface energy characteristics affect the adhesion and static electricity generation between the fiber and the yarn guide plate, and the microscopic morphology determines the contact mode of the fiber and the hairiness generation rate. Our experimental data show that the optimized yarn guide plate can significantly reduce the yarn hairiness, significantly reduce the breakage rate, and effectively increase the equipment operation speed.
