Air shaft principle

Shafts of principle and characteristics: 1. Also called air shaft air shaft, air compression principle is to make the outer diameter of the shaft change, so closely integrated with the volume, the entire volume of material to facilitate the winding and unloading, to promote the rational operation of the production line, simple, precise sexual and automation. 2. When the air is injected into the internal expansion tubes, hoses within the body axis expansion, change the axis of the outer diameter of the body increases, prompting comprehensive and precise reel fixed to the shaft body. 3. When the inside air is released, the expansion extrusion parts is retracted, it can be easy to paper tube is removed. 4. The axis of the main high-stress steel or aluminum alloy, internal expansion body is made of special imported synthetic rubber. 5. And a variety of structural forms: a center conductor moving spline type air shaft / slatted air shaft; surface of the rotary spline type / slat; individually adjustable slip-type air shaft air shaft 6. Many manufacturers , more classic, yet good quality factory in Dongguan City's famous factory machinery.
