Quick Details
Specifications
in packing and printing industry, air expanding shaft is usually matched with safety chuck together for winding and unwinding. There are three types of air expanding shaft: key type, strip type and bladder type.
Description of pneumatic expanding shaft:
Aluminum alloy or seamless steel air shaft with hard chrome-plated surface. Air shaft has the advantage of easy paper tube placing, economic, short charging time, heavy loading, simple maintenance and long service life and etc. It is widely used in printing machinery, paper making machinery and other winding and unwinding machine. It can be match with brake, clutch, pedestal safety chuck, tension controller and so on.
Characters of pneumatic expanding shaft:
1.Air pressure shaft also called air shaft, it uses air pressure changing shaft outside diameter size, so as to closely touch with reel pipe. So as to convenient whole roll material winding and unwinding, making production line operation reasonable, convenient, precious and automatic.
2.When air inlet, shaft inner expanded, components of inner shaft expanded, the shaft outside diameter increase, so the reel pipe touched with shaft closely. When air outlet, expanded components withdraw, shaft can be taken out easily.
3.Shaft core uses high stress steel or aluminum alloy, internal expand components adapts import synthetic rubber, and has various structure types: Strip Type Airshaft, Lug Type Air Shaft, Multi Bladder Airshaft.
Pneumatic expanding shaftCategory:
1.Lug Type Air Shaft
Shaft body uses superior steel pipe, chroming, aluminum convex key stretch flexible, rubber bladder, filling and exhausting gas nipple, good sealing effect, long service life, removable shaft head, convenient for maintenance. Lug type air shaft expanded is single key, fulcrum spreads to all the keys, so keep the shaft force balance. after filling air pressure, one side expanding height can be reached to 5mm to 6mm, it is suitable for heavy loading of winding materials.
2.Strip Type Airshaft
Expanding part is the plates, fulcrum homodisperse, stress uniform, normally the expanding parts can reach to 4mm to 5mm, it is suitable for high precision winding machine or light material winding.
Pneumatic expanding shaft application:
Lug type air shaft expanded is single key, fulcrum spreads to all the keys, so keep the shaft force balance, suitable for light material winding. It is application for slitting, printing, coating, laminating, bag making, paper making and other relevant winding and unwinding machinery, energy conservation and efficient.
