The automatic bagging machine and winding machine consume a lot of power, so
the power we input should be greater than the nominal power on the nameplate of
the shrinking machine, otherwise students are likely to burn out the circuit or
electrical control components. The automatic bagging packaging machine needs to
be grounded as reliably as the baler to protect personal safety.
Each machine leaves the factory with a cable connected to the power supply.
The leading part of the cable end has a power identification symbol, which needs
to be connected correctly. When the specified working voltage of the machine is
three-phase 380V power supply, it is necessary to develop the standard and
three-phase four wire system through the input zero line at the same time. Other
packaging equipment, such as vacuum packaging machine. Otherwise, the machine
will not work properly, and the internal electrical components will be easily
burned.
The automatic bagging packaging machine needs to be installed at the
development level, otherwise the service life of the electric heating tube will
be shortened. For machines with mesh belts, inclined installation will cause the
belt to be off center. When the automatic bagging packaging machine has been
used continuously for more than 3 months, check and replace the heat resistant
wires in the shrinkage chamber according to its aging degree.
When the automatic bagging machine is learning and working, the operator's
palm and other parts are not allowed to contact with different parts of the
machine, especially the temperature requirements of the contraction chamber are
very high, which is easy to burn. After the completion of the packaging design
task of the automatic bagging packaging machine, the heating control switch
should be turned off first, so that the conveying motor and fan motor can
continue to run for about 10 minutes, and then the entire power supply should be
cut off.
First, set the heating time of the machine. After pressing the manual or
automatic control button, the electrical output of the rack cylinder solenoid
valve can drive the gear, and the development of the gear drives the industrial
chain. The close switch behind the frame cylinder is now open. When the rack oil
cylinder moves to the top dead center, the proximity switch in front of the rack
oil cylinder is turned on, and the electromagnetic valve of the oven oil
cylinder gets electric output. When the air cylinder of the oven runs to the top
dead center, the timer starts to work and delay. The control solenoid valve of
the air cylinder of the rack can be closed. When the timing is over, the
solenoid valve of the air cylinder of the oven is powered off. Determine whether
the next workflow can be continued according to the enterprise work management
mode flag.
Preventive measures shall be taken for maintenance. The automatic bagging
machine shall be used in an environment where the temperature is - 10 ℃ - 50 ℃,
the relative humidity is not more than 85%, there is no corrosive gas, no dust,
and there is no explosion risk in the surrounding air. In order to ensure the
normal operation of the vacuum pump of the automatic bagging machine, the motor
system of the vacuum pump is not allowed to back up. Check the oil level
frequently. The normal oil level is 1/2-3/4 of the oil window (not exceeding).
When there is water in the vacuum pump or the color of the oil gradually turns
black, the oil should be replaced at this time (generally, the water should be
replaced once every 1-2 months, or 1 # vacuum booster gasoline or 30 # gasoline
can be used).
Regularly check the triple connection of pressure reduction, filtering and
oil mist to ensure that there is oil in the oil mist and oil cup (sewing oil)
and no water in the filter cup. The heating belt and silicon tape shall be kept
clean and free of foreign matters to avoid affecting the sealing quality. The
two layers on the heating rod and under the heating plate are insulated with
adhesive paste. If it is damaged, it shall be replaced in time to avoid short
circuit.
