The blown film air ring, as a key component on the blown film production line, is mainly responsible for regulating and controlling the cooling speed of the film bubble during the forming process. By precisely adjusting the air volume, the blown film air ring ensures the uniform thickness and superior quality of the film. The design of the blown film air ring integrates principles of aerodynamics and thermodynamics, serving as an important guarantee for the efficiency and quality of film production.
The blown film air ring of the blown film machine mainly consists of the air inlet, the ventilation body, the rotary body, and the upper and lower lips (air outlets). The air inlets are evenly distributed at the lower part or on the sides of the blown film air ring and are connected to the fan through precisely designed air ducts to ensure efficient air input. The ventilation body adopts a labyrinth cross-section design with built-in guide vanes to evenly distribute airflow and establish a stable air pressure environment. The internal cooling air ring is placed inside the film bubble, utilizing the natural phenomenon of hot air rising to efficiently cool the inner surface, which requires tight coordination with the internal cooling die head. Additionally, the upper air ring is fixed by three lifting support columns and can be flexibly adjusted in height according to production needs to achieve precise control of the cooling effect.
The blown film air ring in blown film machines plays an irreplaceable role in film production. By adjusting the air volume, it can effectively control the cooling speed of the film tube, solving the issue of transparency changes during the upward movement of the film tube, ensuring the overall quality stability of the film. Moreover, the energy-saving design of the BOJING blown film air ring not only improves cooling efficiency but also achieves effective energy utilization. In high-end application areas such as food preservation, the advanced technology used in blown film air ring can produce high-performance preservative films that meet the market demand for high-quality products.
With the continuous advancement of blown film machine technology, the blown film air ring for blown film machines is also continually innovating and developing. From material selection to structural design, every step aims to enhance the efficiency, quality, and environmental performance of film production. In the future, the BOJING blown film air ring will continue to bring customers higher-quality blown film air ring and commit to promoting the transformation and upgrading of the film manufacturing industry, pushing the plastic industry towards a greener, more efficient, and sustainable direction.
