1 Release button (Inner ring)
2 Mark Point(Outer Ring)
Two support bearings are installed on the
lifting arm to support the gas fluctuation
shaft equipped with paper rolls. Support
bearings consist of outer and inner rings.
The support bearing is fixed to the
lifting arm through the outer ring, and
the inner ring can rotate and push along
the shaft. Only when the release button on
the inner ring is aligned with the mark
point on the outer ring, the release
button can be pressed, the inner rings of
the two bearing are respectively pushed
outwards / inwards to remove / lock the
gas increase axis. The design of bearing
can prevent the accidental fall off of the
gas fluctuation shaft.
1 Lift arm supports air cylinder
Lift arm is used to support pre-printing
scroll by gas fluctuation shaft. Air cylinder is
used to support lift arm. If the air supply is
insufficient, the lifting arm will remain in its
current position. And then, as a safety
precaution, it drops very slowly.
It prevents
injury to the operator and prevents damage to
the lifting arm.
The role of the air cylinder
itself is used to stop the bottom of the lifting
arm.
