| Malfunction |
Cause |
Solution |
| film breaks |
1. the film itself has a flaw
2. breakdown or poor connection of the film-supply engine
3. proximity switch damaged |
1.get rid of the flaw part
2.repair the connection of the engine
3.change the switch |
| sealed place is not tight |
1.the inside of the film is not even
2.the sealing pressure is not even
3.too low sealing temperature |
1.get rid of the bad film
2.adjust the sealing pressure
3.increase the sealing temperature |
| sealing track is not straight |
the wrong position of the thermal sealer |
readjust the position of the thermal sealer |
| the bag is not cut completely |
1.the cutter in improper position
2.the cutter edge becomes dull |
1.readjust the position
2.sharpen or change the cutter |
| the temperature of the thermal sealer does not increase |
1.the heating pipe is wrong
2.circuit malfunction
3.the fuse is broken
4.the solid relay is broken |
1.change the heating pipe
2.check the circuit
3.change the fuse
4.change the solid rely |
| Sealer termperature uncontrollable |
1.thermocouple in a short circuit
2.something wrong with the temperature controller
|
1.change the thermocouple
2.change the temperature controller
|
| the film-supply engine does not move or stop |
1.the film-supply control stick is stuck
2.film-supply proximity switch does not work
3.capacitor broken
4.fuse broken or Power Panel does not work |
1.adjust the stick
2.change the proximity switch
3.change the capacitor
4.change the fuse and check the Power Panel
|
| color code positioning does not work |
1.wrong parameter for the bag length (usually the actual bag length is shorter)
2.the wheels are worn and less friction |
1.increase the parameter for the bag length, to make it a little longer than the expected bag length
2.change the wheels |
| bags are not pulled (the bag-pulling motor does not work) |
1.circuit problem
2.the bag-pulling proximity switch does not work or the signal wheel too faraway
3.step motor problem
4.control board problem |
1.check the circuit
2.change the switch or adjust the distance of the wheel
3.change the step motor
4.change the control board |
| bags are stuck above the cutter |
1.too early bag-pulling time
2.wrong position of the upper bag-blocking board
|
1. readjust the bag pulling time
2. adjust the upper bag-blocking board
|
| filling motor doesn’t work |
1.position of the proximity switch is not right; control board broken
2.filling motor broken |
1.adjust the position of proximity switch; change the control board
2.change the motor
