The key strip pneumatic shaft, also known as the air-expandable shaft, is a specially designed winding and expanding shaft that operates based on the principle of inflation. Here are some key points about the key strip pneumatic shaft:

1. Structural Composition: The key strip pneumatic shaft mainly consists of a hollow axial body, an airbag, key strips, axial heads, and an air nozzle. These components work together to enable the inflation and winding functions of the pneumatic shaft.

2. Working Principle: In practical applications, an air source is required, and the air pressure should be controlled within the range of 6~8kg/cm². When it is necessary to lock the external components (such as round paper tubes), the air nozzle is inflated using an air inflation handle, causing the airbag to expand and push the key strips outward to secure the external components. When it is necessary to release or unload the materials, the sliding air core on the air nozzle is pressed to deflate the airbag, allowing the key strips to return to their original state and enabling easy removal of the external components.

3. Features and Advantages:

• Short inflation time: The separation and placement of the key strip pneumatic shaft and the paper tube can be completed in just 3 seconds through inflation and deflation, providing convenient and efficient operation.
• Simple paper tube placement: The inflation and deflation actions facilitate the movement and fixation of the paper tube to any position on the axial surface.
• High load capacity: The pneumatic shaft can be customized with different axial diameters based on actual needs and is made of high-strength steel, enabling it to withstand significant weights.
• Economic efficiency: Its unique design caters to various thicknesses, widths, and narrownesses of paper tubes, enhancing overall efficiency.
• Easy maintenance and long service life: Each component of the pneumatic shaft has a fixed specification and is interchangeable, facilitating inspection, repair, and maintenance, thus extending its service life.

1. Application Scope: The key strip pneumatic shaft is widely used in printing, coating, laminating, slitting, laminating, paper, and other related mechanical equipment for winding and unwinding operations. It effectively improves work efficiency and is suitable for winding heavier materials such as fabrics, paper products, films, printed materials, leather, and composite materials.

Overall, the key strip pneumatic shaft is an efficient and convenient winding device that utilizes its unique structure and working principle to achieve rapid and stable winding operations, widely applied across various industries.
