4-3 Frequent trouble and troubleshooting
Cannot output straps automatically: in this situation, check whether the “adjustment of the
length” of the strap is at “0” position first, and then check whether the strap threads correctly.
For example, if the machine is at the zero position it will not release any straps. And if there is
something that is large around the strap-feeding roller, this problem will happen too.
Adhesive effect is not so good:
A. If the temperature is too high or too low, the viscosity of a special strap is not as good,
The temperature must be correct.
B. Voltage is not enough: The power supply in many factories is often not enough. If you
use an extension or cable wire, it will result in a reduction of power. So this lowers the
original temperature and the strapping motor will burn out. Therefore the use of an
extension or cable wire should be avoided. If the extension or cable wire must be used,
adopt thicker, not longer wire.
C. If the 635 bearing below the middle cutter is damaged, then it only affects the warming
and can’t stick completely.
D. If the long spring of the pendulum bar is worn out, it cannot pull the pendulum bar to the
correct position, thus leading to part adhesion.
E. If the electric heating steel sheet is not in the correct position so that it touches the PP
straps on the top and bottom or left and right cutter, and so that it cannot heat up, adjust
it according to the actual circumstance or application of use.
Inserting strap, no action:
A. Trouble with inching switch on LS1 that is below the slide plate or shrapnel is stopped
by something, and so it can’t touch contact point.
B. The machine is not at the home position, so insert strap and if there is no action; it is
necessary to push the reset button and start again at the beginning.
C. M1 motor ‘s carbon brush is wear; Motor does not turn or rotation powerless.
Continue action:
A. LS1
trouble.
B. No trouble for LS1 other than a small object is caught between contact point and spring
slice or the spring slice itself is caught so that it cannot be released after inserting the
strap as usual.
C. situ micro switch (LS2) bad plug with no response
，
Press the jog host directly to stop
after four laps in the cooling position (to the highest point of the cutter at the top); press
the jog repeat this action. This behavior can be determined for the LS2 switch is broken.
D. Back with a micro switch (LS3) bad, insert after rebate with a belt
，
Host a turn directly
back into place to stop, you can jog belt, insert strap and repeat this action. This
behavior can be determined if the LS3 switch is broken.
