Conveyor Belt Tension
Check the tension of the conveyor belt on the
infeed and outfeed rollers
– the conveyor belt
should be tight enough that you cannot shift it
with your hands. If the conveyor belt needs
tightening, proceed as follows.
1. When running conveyor belt.
2. Rotate the adjustment screws (the left one
is shown in Figure 11) as needed with a
wrench. Rotate clockwise to increase
tension, counter-clockwise to decrease
tension.
NOTE: Do not over-tighten the screws as this
will hasten wear of the conveyor belt. However
new belts will stretch in the first couple of weeks.
Conveyor Belt Tracking
The conveyor belt should remain centered upon
the rollers during operation. If it approaches to
either the left or right side, adjustment is
necessary.
First check that the conveyor belt tension is
correct. If the tension needs adjustment, do this
first before you adjust the tracking (see
“Conveyor Belt Tension”). Then proceed as
follows.
Conveyor belt tracking should be adjusted while
the conveyor belt is running. Make adjustments
in increments ( ¼ turn at a time )and allow the
conveyor belt time to respond to each change.
