5. Structure and Principle
The machine composes of organic cover, vacuum chamber, machine body, electric appliance and vacuum
system. The vacuum chamber has heat-seal device and the heating element is nickel belt which installed on
heat-seal frame and insulated with vacuum chamber. Heat-seal frame touches closely on ballonet, which is in low
vacuum state before heat-sealed. When heat-seal, ballonet connects the air through solenoid valve, then ballonet
becomes big and heating element is pressed down. Press sealing part tightly and heat, the heating temperature and
time can be adjusted.
The machine power is AC 230V 50Hz, the motor for vacuum pump is AC230V. This heating system is
pressure adjustable type. Its means, the fist class of heating transformer is 220V, and second class has three shifts
(high, middle, low). Charging the power of second class can charge the sealing temperature, but the heat-seal
temperature is adjusted by button in panel.
The vacuum system composes of heat-seal electromagnetic valve YV2, release electromagnetic valve YV1.
When star the vacuum pump, vacuum chamber is drawing out the air. When reaches the preset vacuum degree, the
vacuum system stops running and next process will star, and automatic seal and release at one time.
6. Control panel indication
1) Control panel
There is vacuum meter, emergency stop key, setting key, adding key, reducing key, temperature adjusting key,
time display key and some pilot lamp.
2) Machine enters into waiting state when closed the air switch behind machine, Then set Vacuum
degree, sealing time, cooling time and sealing temperature.
a. to adjust vacuum degree: Press SET Button, the vacuum pilot lamp is on. Machine enters the setting
state of exhausting time, it shows the current exhausting time on time monitor, Meanwhile, user could
set the vacuum time according to the packing product. Press up and down key to change the vacuum
time. The longer time, and the higher vacuum degree, on the contrary, the lower degree of short
time(the range of exhausting time is between 1-99 second). Press “set” key, again after getting the
required exhausting time, and the “sealing pilot lamp” is on, and the machine enter the heat-seal time
setting state.
b. To set the sealing time, press “set” two times, the “sealing pilot lamp” is on. The machine enters the
setting state if sealing time, and it shows the current sealing time. Set sealing time according to the
thickness and material of vacuum-bag, press up and down key to increase or reduce the sealing time
(the range of sealing time is between 0.1-9.9 second). Press “set” again after setting sealing time, and
the “cooling pilot lamp” is on and then machine enters the cooling time setting state.
c. To set the cooling time: model
VAKSIC-8 E
/
VAKSIC-10 E
: press “set” key three times, the “cooling
pilot lamp” is on, and the machine enters the setting state of cooling time. It shows the current cooling
time on time monitor, and user set the cooling time according to the sealing time and sealing
temperature. Press up and down key to increase or reduce cooling time (the range of cooling time is
between 0.1-9.9 second). Press “set” key again after sealing cooling time, and show “ED” that indicate
setting is success, and machine start to run according to your setting digital. Model
VAKSIC-20 2A E
/
VAKSIC 20L 2A E
/
VAC-20E
: the cooling time and heat-seal time is the same as the above.
d. To set the Sealing temperature is adjusted according to thickness and material of bag. The adjustment
of temperature have three shifts: high-middle-low. There are three pilot lamps on panel, in which have
the neutral shifts (pilot lamp is off, it indicate that there is without temperature). Press the “temperature
adjustment” key on time, the pilot lamp beats on time, continues to press it, the temperature circulate
beat among three shifts and neutral shift. As long as pilot lamp in any shift is on, it indicates the
temperature is this shift one.
e. Vacuum degree, sealing time, cooling time and sealing temperature are set by the requirement of
user.
