2. After the power supply being connected, the heating element produces heat
that rapidly raise the temperature of both upper and lower heat blocks. By using
the temperature controller and speed-adjusting mechanism, adjust it to the
needed temperature and speed. The plastic packing bag is transmitted by
conveyor belt, and its sealing part will be conveyed into the middle of two
working sealing belts. Then it is clamped by the two sealing belts and conveyed
into the heating area, and sealing part is pressed by two heating blocks and
impressing wheels there, which could make the plastic film fused and stuck
together. After this, the sealing part will be conveyed into the cooling area for
cooling, and then to be pressed by embossing wheel for making stripe or netted
pattern, at last, colored label on the sealing part will be coded by printing wheel.
The sealing and printing transmission are driven by one motor, which drives
sealing belts, guiding belts and conveyor belt to work synchronously, as well as
make printing mechanism working intermittently.
3. Power of vertical sealer makes sealer head run through vertical shaft.

2. Prepare the machine for use
1) This machine is equipped with a three-pin crust-grounded socket. Please check
if it is well connected so as to ensure safe operation.
2) First-time use or too long intermission will make the heating elements damp. So
it is necessary to preheat at lower temperature for several minutes before the
normal operation.
3) Adjust the height and position of the conveyor table to get the required sealing
position.
4) Adjust the position of feed opening according to the external size from sealing
line to bag opening.
5) According to the thickness and material that to be sealed, adjust the clearance
between two heating blocks and two cooling blocks, so that both clearances are

7
approximately equal to the thickness of packing bag in one layer. The firmness
of sealing and high definition of embossing shall be guaranteed, also suitable
length extended from two ends of sealing part shall be ensured.
3. Ways of replacing and adjusting the sealing belt:
1) Remove the safety cover, when heating blocks become cooled, rotate retaining
washer in the upper heating block and lower cooling blocks by 30 degrees, and
lift these two sections. At same time loosen the middle pressing wheel and
middle pressing wheel spring, and remove guiding belt to prepare for removing
sealing belt.
2) Push and move the driven wheel seat (adjusting block) in the direction of
heating blocks, then remove the sealing belt.
3) Replace with a new sealing belt and install the guiding belt back.
4) Put the driven wheel, heating and cooling blocks, pressing wheels, and etc. to
the original position, meanwhile rotate cam clockwise to make it return to
original position as well.
5) Connect the power supply and test the machine, if irregular sealing appears on
the belt, make adjustment by adjusting screws on the driven wheel seat

2) The adjustment of the clearance between ink roller and types:
Adjust the adjusting screw (5) for the ink roller’s swing pole, rotate the printing
wheel, and make the types’ surface touch the ink roller’s (1) surface slightly. If
the ink roller can be easily driven by rotating the printing wheel with hand, it
should be ok (see Diagram 8).

3) Adjustment of the pressure between printing wheel and silicone wheel:
The types on the printing wheel would not touch the silicone wheel when it is
not in printing process. And they only touch each other when the printing work is
in process. Loosen the screw (4) in the front of the silicone wheel, then rotate
the eccentric sleeve (3), so as to make the types’ surface slightly touch the
silicone wheel’s (2) surface. If the machine is used to print relatively thicker
packing bag, the screw should be loosened accordingly and the pressure may
not be oversized, fasten the screw (4) after making adjustment (see Diagram 9).

4) Temperature adjustment for printing wheel and ink roller:
All the knobs of this machine are set to position 0 before leaving factory. Users
need to make adjustment by themselves. For a new ink roller, during previous
time of using, the temperature should be relatively lower, after a period time of
using, the temperature can be raised to higher degree, which can make the
deep-seated ink ooze and prolong the ink roller’s life-span. When the ink roller
reaches the working temperature, use a piece of white paper to touch the ink
surface, as long as it can stick a little ink, it should be ok. The temperature can’t
be too high or too low.
The ink roller that suits for this machine specified in following table, including
colors of white, yellow, red, blue, green, brown and black. If the packing bag
needs steam cooking after printing，you should choose the ink rollers of
moderate temperature or high temperature, in this situation, the temperature
must be set in higher degree accordingly while using.

First of all, dismantle the platens (10) in left and right sides of the conveying
board and the discharge plate (11). Then rotate the adjustment knob (9)
counterclockwise and remove it. Move the driven roller shaft to make it in the far

12
left end of the slot. Then remove screw (1) (total 6 pcs), loosen screw (3) (front
two pcs) to drag off the front baseplate (6) and motor safety cover(4). At this
point, the conveyor belt is in a fully loosened state and finally unload conveyor
belt.
9. Starting procedure
1) Connect the power supply and turn startup switch on, the indicating light will
light, then adjust the speed-adjusting knob and all transmission parts will start to
run synchronously.
2) Fine tune the knob of embossing wheel to make that wheel swivel, after getting
a proper pressure, fix limiting screw.
3) Once turn the heating switch on, the green light of the electronic temperature
controller will light. According to the material and thickness of the packing bag,
adjust the temperature controller to the required temperature, then set the
position of ink roller heating knob. Once the heating blocks and ink roller
heating blocks begin to preheat, the machine needs to be started meanwhile
and kept running at low speed.
4) That whether it is necessary to turn on the fan for cooling depends on the
material and thickness of packing bag.
5) Flatten and align sealing opening, then deliver the bag by aligning the bag
opening with the feed opening, when the bag opening is gripped by the sealing
belts, which makes the bag move forward automatically, at that moment, please
do not push it in or pull it out by force, otherwise irregular sealing or breakdown
will happen.
6) If it is found that there is dirt attached to the sealing belt or the heating block,
you need to stop the sealer and clear it.
10.Stop operation
In order to prolong the using life-span of the sealing belt, please remember,
before shutting down the machine, you should return the temperature
regulating knob to position 0 first, then turn on the fan, the temperature on the
indicator begins to fall and the sealing belt should still be in state of running at
this time. About several minutes later, when the temperature drops below 100℃,
only can you turn off the fan and main power supply.
11.Emergency stop switch:
At any time, the machine should stop immediately when pressing emergency
stop switch. The emergency stop switch is a self-locking switch, and needs to
rotate clockwise 120 degrees to open it after self-lock.
