6.1 Control panel (see Fig. 4)
Figure 4
6.2 Prepare the machine before use
6.2.1 This machine is equipped with grounded socket. Please check whether it is well
connected so as to ensure operation safety.
6.2.2 First-time use or too long intermission will make the electronic heating elements
moistened, so several
minutes’ low-temperature preheating is necessary before normal
operation.
6.2.3
Adjust the conveyor table’s height and horizontal position to meet the packing
requirement.
6.2.4 According to the distance from sealing line to the edge of bag opening, regulate the
position of feed opening.
6.2.5 According to the material and the thickness of the object to be sealed, adjust the clearance
between upper heating block and bottom heating block, as well as the clearance between
upper cooling block and bottom cooling block. Adjust the clearance between two sealing
belts by adjusting stopping flakes 2 according to Fig.5, specifically, turn the stopping flake
clockwise to raise block (increase clearance) or counterclockwise to lower block (decrease
clearance). The clearance between two sealing belts should be equal to the thickness of the
packing bag in one layer approximately, which must guarantee sealing fastness,
high-definition embossing and ensure proper length extended from two ends of sealing area
as well.
6.2.6 Exchange and adjust the sealing belt
6.2.6.1 Remove the safety cover, after the heating block get cool, turn stopping flakes on both
upper heating block and upper cooling block by 90° to lift both two blocks, then loosen the
springs on both embossing roller and pinch roller, meanwhile, remove the guiding belt, so as
to make it ready for removing sealing belts. (see Fig. 5)
