Double Air Ring Tuyere

In the mechanical industry, the double air ring tuyere is a key functional component of the film blowing machine, designed to optimize the film cooling process. Its core function is to provide more uniform cooling air volume for the film bubble tubes during the film blowing process through a unique dual air ring structure, thereby achieving efficient cooling of the film bubble tubes. As the core component of the cooling system of the blown film machine, it directly affects the forming quality and production efficiency of the film. It is widely used in the blown production of plastic films (such as PE film and PP film) and is an important link to ensure the stable performance of film products.

The core of the structure and principle of the double air ring tuyere is the "dual loop collaborative air control": it includes two independent air rings, upper and lower, which can adjust the air volume and speed separately; After the blown film machine extrudes the bubble tube, the upper ring is initially cooled to suppress expansion, while the lower ring cools the key areas in the middle and lower parts to avoid uneven cooling of a single air ring and ensure stable bubble tube shape.

The core value of double air ring tuyere for blown film production is: firstly, uniform cooling reduces film defects, improves transparency and smoothness, and adapts to products with high transparency requirements; The second is to expand the cooling range, flexibly adjust the air volume, shorten the cooling time to increase production, and also reduce the deviation of film thickness to ensure stable quality.

Double air ring tuyere are suitable for mid to high end blown film production lines, especially for high-quality film production: improving transparency and sealing in the food packaging film field, increasing efficiency and strength in the agricultural film field, and ensuring tensile performance in the industrial packaging film field; It is also possible to adjust the air volume to adapt to different materials of films, enhancing production flexibility.
