There are ten common faults in flat screen printing machines, and the causes and methods of each type of fault are different.
The first type of failure phenomenon: when the flat screen printing machine is in a semi-automatic state, the foot screen switch is not stepped on, and the flat screen printing machine operates.
The cause of this type of failure is mostly due to damage to the foot switch causing a short circuit on the flat screen printer. New switches and sockets can be replaced in time.
The second type of failure phenomenon: when the flat screen printing machine is semi-automatically operated, the slide of the foot switch is lowered and then rises.
This phenomenon usually occurs because the cross slide has failed. The solution is to turn on the switch connection.
The third type of failure phenomenon: When the flat screen printing machine is working semi-automatically, the printing seat will not continue to work after moving to the left.
The reason is that the left side of the cross slide is not sensed or has a problem. You can adjust the sensing point of the left proximity switch or replace the proximity switch with good performance.
The fourth type of failure phenomenon: when the flat screen printing machine is working semi-automatically, the sliding seat only moves left and does not move right.
Generally, the switch on the upper left side of the vertical slide is not sensed. The solution is to adjust the proximity proximity switch sense.
The fifth fault phenomenon: when the switching step is performed, the rising motion is slower than half a beat.
This type of failure is to control the solenoid valve to malfunction. The only solution is to replace the solenoid valve.
The sixth failure phenomenon: manual and semi-automatic can not work.
The reason is that the fuse on the low voltage side is blown and the air source cannot enter. We can replace the fuse on the low side and check if the pressure in the flat screen printer reaches 4-7kg/cm.
The seventh failure phenomenon: automatic and semi-self-work can not fall.
The switch on the right side of the cross slide has a fault and the selector switch has failed. By adjusting the proximity switch sensing, replace the selector switch to solve.
The eighth fault phenomenon: the automatic system of the flat screen printing machine cannot be started.
This type of failure is that the switches of the upper and lower cylinders are all closed, resulting in the contacts not being able to conduct. The solution is to fix the micro switch on the top and bottom.
The ninth failure phenomenon: the work surface of the flat screen printing machine can not be inhaled.
The reason is that the motor used for inhalation may have burned out and malfunctioned. The solution is to repair or replace the suction motor.
The tenth failure phenomenon: the speed at which the vertical carriage rises and its slowness.
The reason is that the cylinder piston of the vertical slide is worn. The solution is to adequately replenish the oil and replace the cylinder piston's password.
