Slitting Line Fault Maintenance Tips
Slitting line in the uncoiler device in the entire steel coil slitting process has an important role, the entire steel coil needs to be slit into small steel coils, the outline volume must be uncoiled operation, this series of necessary processes to complete the entire steel coil slitting process, and the entire production of slitting machine, steel plate slitting line, the uncoiler will also encounter some common problems.
1, uncoiler overload, inverter overcurrent alarm
1, uncoiler overload, inverter overcurrent alarm
Solution, turn off the total power supply of the electronic control system, restart can be.
2, gearbox gear damage
2, gearbox gear damage
First of all, turn off the total power supply, and then turn the uncoiler head by hand to observe whether there is a jamming phenomenon. If there is a check gearbox gear, longitudinal shear line, timely replacement of damaged devices.
3, in the top of the uncoiler guide device photoelectric proximity switch or buffer pit at the bottom of the photoelectric proximity switch is damaged, cannot detect the silicon steel sheet proximity signal, should be given to replace.
The following are the reasons and countermeasures for the uncoiler‘s uncoiling head not to rise or shrink
1, the uncoiler hydraulic up tightening solenoid valve output line roadblock, may lead to solenoid cannot be normal action.

1, the uncoiler hydraulic up tightening solenoid valve output line roadblock, may lead to solenoid cannot be normal action.
Solution, longitudinal shear line which is good, check the circuit diagram to check the output action of the solenoid valve insurance has not burned, if there is a problem, the need for replacement.
2, uncoiler uncoiling head tensioning device oil pressure is too small, tensioning mechanism wear, resulting in the loosening of the tensioning piece.
2, uncoiler uncoiling head tensioning device oil pressure is too small, tensioning mechanism wear, resulting in the loosening of the tensioning piece.
Therefore, the hydraulic oil should be replaced once a year, so as to maintain the viscosity of the hydraulic oil, but also regular lubrication maintenance of the uncoiling head.
These are some common problems of the uncoiler, and its solutions, you can refer to the various methods above, simple maintenance of the uncoiler, so as to achieve a longer time to use the role of the uncoiler.
