film being cut will remain in the film roll.
5.6.4 If do not use for cutting film, only need to lift up the tool carrier up gently,
and the tool carrier will automatically fasten to the cutter shaft without turning
and falling.
5.7 The adjusting method of film perforating device is the same as the cutting
device.
5.7.1 The perforating knife is placed in the edge of film about 1-3mm.
5.8 Use and control of hydraulic oil station
5.8.1 Please see its work principle clearly as the drawing 3.
5.8.2 Work principle: Motor drives the oil pump, the pump will suck the oil from
the oil tank, and the oil will pass through hydraulic valve to do the pressure and
direction adjustment. The oil will be transported to the oil cylinder through the oil
pipe.
5.8.3 Set the system pressure. Start the oil pump, turn on the remote overflow
valve, which outside direction means increase pressure, inside direction means
decrease pressure, it can be set based on the pressure gauge.
5.8.4 There install a safe overflow valve on the oil tank, its set pressure is the
system
’
s max pressure, not allow adjusting during operation. Please make the
hydraulic station stop working if the valve is abnormal. And ask professional
technician to check it
5.8.5 The Max. Pressure is set at 21 Mpa; when the adjusted pressure is over than
this pressure, the safe overflow valve will unload the pressure automatically to
ensure the operation safety
5.9 Adjustment of separating unit
5.9.1 First should fix the declining wheel on the side of the perforating unit with
the angle of 10--15 degree; the decline wheel also should be pressed on the
delivery belt and make sure that it can move when the machine is running
without paper. Adjust the pressure of decline wheel to make it wobble up and
down, and let it touch the belt.
5.9.2 The distance should be more than one piece of paper's length between two
cutting rollers. You can move the hand wheel to control the distance as the
requirement.
5.9.3 T
he pressure (left and right side) of front separating roller should be well
