Before using the device, please make
sure that the compressed air source is clean and dry,
and the working pressure is 0.4-0.6mpa.
1. The hopper of the feeding machine
is generally fixed on the receiving equipment, or fixed
on the hand-cranked trolley. When fixed on the
hand-cranked trolley, the hopper can move up and down.
According to the height of the receiving equipment,
adjust the hopper of the feeding machine. When the
hopper of the receiving equipment (such as the packaging
machine) is high, the hopper of the vacuum feeder needs
to be fixed on a special support.
2. Connect the suction nozzle to the
hopper through a hose, connect the hopper and Roots
blower with a hose, and tighten the hopper with the hose
clamp.
3. Connect the power supply. The
power supply should adopt three-phase five-wire cable,
because the control circuit needs ‘work 0’, and
‘protection 0’ is still needed for safety. Another
function of the ‘protection 0’ is to eliminate the
interference of the static electricity generated during
material conveying to the control chip to avoid causing
the control system to crash. Therefore, the 'protection
0' must be connected.
4. Insert the Φ10 compressed air tube
into the air inlet of the system (filtering and pressure
reduction), adjust the pressure reducing valve to ensure
that the pressure of the system is maintained at 0.6Mpa,
and connect the external compressed air pipe joint and
the external compressor air connector on the vacuum
hopper according to the pipe connection diagram.
5. Turn on the power, open the box
door, and turn on the three-phase air switch. At this
time, the feeding time and discharging time displayers
on the control box are on.
6. Adjust the feeding time and
discharging time. By pressing the increase and decrease
buttons, set the feeding time to 8-20 seconds, and set
the discharging time to 4-8 seconds.
7. Press the on/off button to turn on
the vortex air pump. Check the rotating direction of the
vacuum pump. If there is no air exhaust from the exhaust
port, the motor conducts reversal rotation, turn off the
on/off button, and change the wiring phase sequence of
the power supply until the air pump rotates correctly.
8. Press the on/off button to start
the vortex air pump, insert the suction nozzle into the
material box, and start feeding. Suction-discharge
(simultaneously compressed air conducts back flushing on
the filter) is a working cycle. The vacuum feeder will
automatically cycle until the hopper of the receiving
equipment (such as the packaging machine) is filled with
materials (the material level switch is on at this
time).
9. When the material level in the
hopper of the receiving equipment is lower than the
material level switch, the pneumatic three-way valve
automatically conducts reversing operation, and the
system enters the suction-discharging cycle again until
the hopper is filled with materials.
10. In the material conveying
process, large static electricity will be generated due
to friction. In order to eliminate the static
electricity, reliable grounding of the equipment shell
should be taken into account. |
