What is the air shaft used for?

‌Pneumatic shafts are mainly used in winding and unwinding equipment. The surface can bulge after high-pressure inflation, and the surface part quickly shrinks after deflation, thereby realizing the surface expansion and contraction tension control of the shaft. Pneumatic shafts are widely used in various mechanical equipment, such as die-cutting machines, slitting machines, coating machines, winding machines, etc., to facilitate loading and unloading, save time, and improve work efficiency. ‌

Working principle of air shaft

The inflatable shaft uses high-pressure gas as a power source, and controls the bulge and retraction of the surface by inflation and deflation. Specifically, when inflated, the surface of the inflatable shaft will bulge, thereby tightening the paper tube or cylinder; after deflation, the surface part will shrink rapidly.

Application areas of air shafts

Inflatable shafts are widely used in many industries, including the printing industry (such as board drying machines, flexographic printing machines, gravure machines, trademark printing machines, etc.), light metal industry, waterproof coil production lines, various coating machines, leather machines, shaping machines, embossing machines, slitting machines, rewinding machines, paper tube machines, bag making machines, laminating machines, film blowing machines, foam board production lines, laminating machines, embossing machines, papermaking machines, non-woven fabric machines, cloth inspection machines, hot stamping machines, battery film winding equipment, etc.

Advantages of air shafts

‌Short inflation operation time‌: The separation and placement of the inflatable shaft and the paper tube can complete inflation and deflation in just 3 seconds, and there is no need to disassemble any parts on the shaft end to tightly engage.

‌Easy to install and place‌: The paper tube can be moved and fixed to any position on the axis surface by simply inflating and deflating.

‌Large load-bearing capacity‌: The shaft diameter can be customized according to customer needs, and high-stress steel is used to carry a large load.

High precision in use: The shaft is made of alloy steel, which has strong deformation resistance and small circular runout, ensuring the product qualification rate.

High economic efficiency: The shaft is designed with special functions and is suitable for paper tubes of different thicknesses.

Simple maintenance: As a single component, each part in the internal structure of the air shaft has corresponding fixed specifications and can be interchanged, reducing maintenance costs.
