Common faults and solutions of screen printing machines

Screen printing machine in the printing process there will always be a variety of fault problems, such as manual, semi-automatic all non-action, power light, printing seat left after the move is not moving and so on.

One: Semi-automatic when not stepping on the foot switch and immediate action This type of failure is mostly due to foot switch damage or foot switch socket water caused by short circuit, the other is the manual start button switch has a problem.

The repair method is to replace the new switch, socket, button switch or disassemble the repair related damaged parts.

Second, semi-automatic work when stepping on the foot switch slider drop, let go and then rise.

This phenomenon is generally the left side of the transverse sliding seat close to the switch damaged or disconnected, the solution is to replace the proximity switch or switch on the connection.

Third, semi-automatic work when stepping on the foot switch vertical sliding seat drop, the printing seat left after the move is not moving.

This failure occurs because there is no sensing or problem with the proximity switch on the left side of the transverse slider. The solution is to adjust the left proximity switch sensing point or replace the close switch, as well as the pedal switch inside the microswitch jammed do not move, will also cause this failure.

The solution is to adjust, repair, or replace the new Microswitch with the Microswitch inside the pedal switch.

Four, semi-automatic work when stepping on the foot switch, sliding seat drop left after moving up but not right.

The occurrence of this phenomenon is that the upper left of the vertical sliding seat near the switch is not sensed or close to the switch problem, the solution is to adjust the upper proximity switch induction or better proximity switch.

Five, the action switch after the rise action slow half beat.

This kind of failure is to control the solenoid valve has foreign body obstruction or solenoid valve failure, the solution is to remove the magnetic valve clean or replace the good solenoid valve.

Six, manual, semi-automatic all do not move, power light. The cause of this kind of failure is low-pressure side fuse burnout, no gas source into, solenoid valve are all faulty.

The solution is to change the low-voltage side fuse, check whether the pressure reached 4-7kg/cm, solenoid valve All fault is very small, mostly wired break.

Seven, automatic, semi-self-startup does not decline. This kind of failure occurs is the right side of the horizontal sliding seat near the switch is faulty or not sensed, select Switch fault, single switch chain point damage.

The solution is to adjust the proximity switch sensing or replace the right proximity switch, replace or repair the selector switch and the single switch.

Eight, automatically unable to start.

This type of failure is the upper and lower cylinders of the micro-switch is always closed, contact can not pass or the timer damage, the solution is to repair the micro-switch, or replace the timer.

Nine, the workbench does not inhale. The reason for this type of failure is that the suction motor is burned.

Control motor Operation contactor damage, suction motor rotation, but control suction solenoid valve fault, suction choice switch fault, solution repair or replacement.

Ten, the vertical sliding seat rises slowly. The reason for this kind of failure is that the vertical sliding seat bearing is oil-free or cylinder piston wear, the magnetic collision makes the Axis bend, the solution is to supply oil, replace the piston password, adjust the axis.
