Main action principle of air shaft is fill
compressed air into air shaft to extend outside
diameter of shaft.
This
action fix core on the shaft very tight, special
suit whole roll material reeling or unreeling,
for these profits offer production line has
reasonable, easy and convenience, accuracy and
automatic operation.
The
shaft made of high tension steel, aluminum alloy
and the rubber tube made by special material of
rubber.
When
air fill into rubber tube, the tube will blow up
to force lug plate to go out, and extend the
outside diameter of shaft, that will fix core on
overall shaft very tight and accurately center,
when air release from tube, the lug plate will
go back by spring, then very easy to take away
core. |
