Description

TECHNICAL FIELD

[0001] The utility model relates to a silk reeling machine silk tension technology field, concretely is a silk reeling machine twist sheath tension regulator. BACKGROUND

[0002] The silk tension regulator controls the tension of the silk in the twist sheath process of the silk reeling machine, ensuring its stability and quality in production. By adjusting the tension of the silk, the regulator can effectively prevent the silk from breaking, thinning or having defects, thereby ensuring the uniformity and smoothness of the final product. Its structure is usually composed of a spring, an adjusting screw, a guide wheel or a tension wheel. The spring, as the core component, provides elastic force, the adjusting screw is used to adjust the pre-tightening force of the spring, thereby controlling the tension of the silk, and the guide wheel guides the flow of the silk to ensure its smoothness. The adjustment process mainly relies on the operator to fine-tune the adjusting screw according to the actual state of the silk to adjust the pre-tightening force of the spring, thereby achieving precise control of the silk tension. In production, the operator needs to observe the state of the silk, such as whether it is loose or too tight, and fine-tune the adjusting screw based on experience to ensure that the silk is always within the ideal tension range. This adjustment process requires careful observation and certain operating skills to ensure the stability of the silk in different processes. However, the above adjustment process requires the staff to check and judge the silk tension at irregular intervals and adjust the regulator according to the silk tension. However, in the production process, the silk tension changes dynamically and continuously, and is affected by many factors such as environmental temperature, humidity, machine vibration, and raw material differences. It is difficult for the staff to closely monitor the state of each section of silk in a limited time, especially in large-scale or continuous production, often needing to switch between multiple links, which may overlook some details or delay adjustment, which may cause the silk to be loose or too tight, affecting the uniformity and quality of the product.
