b) X-conveying timing belt
① Check the X-conveying timing belt tension by detaching the upper cover of X fixing frame from the body of the
machine and using sonic belt tensiometer.
② Adjust the X-conveying timing belt tension by moving the X conveying frame ① to the left end and then flipping with
fingers or sticks the middle of the belt that stretches from the end of the timing belt fixing plate block ② to the X-final
operating pulley ③. Make sure that the measured value of the sonic belt tensiometer is 26 ~ 27kgf.
③ Input data for the sonic belt tensiometer, when adjusting X-conveying timing belt tension.
Weight: 3.8gf/m
Wide: 35mm/#R
Span: 566mm
④ In order to adjust X-conveying timing belt tension, unfasten the nut ⑤fastened on the tension adjusting bolt ④ and
unfasten the bolts⑦ (four) that fix the final operating pulley bracket to the extent that the bracket ⑥ can move.
[Caution]
Turning tension adjusting bolts④ without unfastening fixing bolts⑦ will lead to physical damages to the machine.
⑤ Turn the tension adjusting bolts④ clockwise. Then the final operating pulley③ and the final operating pulley bracket⑥
will be pushed into the direction of the bolt, which leads to the increase of tension of timing belt. And turning the bolts
④ counter_clockwise will decrease the belt tension.
⑥ After adjusting tension of the belt, fasten nuts② and fixing bolts⑦ firmly.
⑦ Fasten ⑥ using the four bolts which tighten the bracket.
