In the printing process, the screen printer will always have various faults, such as manual and semi-automatic all not working, the power light is on, and the printing base does not work after moving to the left. Next, licheng Flat Screen Printing Machine Factory will conduct a specific analysis on this aspect.
The first kind of malfunction phenomenon: It acts immediately without stepping on the foot switch in semi-automatic mode.
The reason for this type of failure is mostly caused by a damaged foot switch or a short circuit caused by water in the foot switch socket. The other is a problem with the manual start button switch. The repair method is to replace the new switch, socket, button switch or disassemble and repair related damaged parts.
The second fault phenomenon: The slide seat of the foot switch descends when it is working semi-automatically, and then rises after releasing it.
This phenomenon is generally caused by damage or disconnection of the proximity switch on the left side of the horizontal slide. The solution is to replace the proximity switch or connect the switch connection.
The third symptom of the fault: the vertical slide is lowered by stepping on the foot switch during semi-automatic operation, and the printing seat will not move after moving to the left.
The reason for this kind of failure is that the proximity switch on the left side of the sliding seat is not sensed or there is a problem. The solution is to adjust the sensing point of the left proximity switch or replace a good proximity switch; and the micro switch in the foot switch is stuck and does not work, which can also cause this fault. The solution is to adjust, repair or replace the micro switch in the foot switch.
The fourth fault phenomenon: Step on the foot switch during semi-automatic operation, the sliding seat descends and moves to the left and then rises but does not move to the right. This phenomenon occurs because the upper left proximity switch of the vertical sliding seat is not sensed or the proximity switch has a problem. The solution is to adjust the upper proximity switch induction or a better proximity switch.
The fifth fault phenomenon: the rising action is half a beat slow after the action is switched. This type of failure is that the control solenoid valve is blocked by foreign matter or the solenoid valve is faulty. The solution is to remove the solenoid valve to clean or replace the solenoid valve.
The sixth failure phenomenon: manual and semi-automatic all do not work, the power light is on. The cause of this type of failure is that the low-voltage side fuse is blown, no air source enters, and all solenoid valves are faulty. The solution is to change the low-voltage side fuse, check whether the pressure reaches 4-7kg/cm, all the solenoid valves have very small faults, most of which are disconnected.
The seventh failure phenomenon: automatic and semi-automatic start does not drop. This type of failure occurs when the proximity switch on the right side of the slide is faulty or not sensed, the selector switch is faulty, and the single-action switch interlocking point is damaged. The solution is to adjust the proximity switch induction or replace the right proximity switch, replace or repair the selector switch and single-action switch. The eighth failure phenomenon: automatic failure to start. This type of failure is that the micro switch of the upper and lower cylinders is normally closed, the contact cannot be conducted or the timer is damaged. The solution is to repair the micro switch or replace the timer.
The ninth failure phenomenon: the work surface does not inhale. The cause of this type of failure is that the suction motor burns.
The contactor that controls the operation of the motor is damaged, the suction motor is rotating, but the control suction solenoid valve is faulty, the suction selector switch is faulty, and the solution is repaired or replaced.
The tenth fault phenomenon: The work surface does not inhale because the solenoid valve controlled by the suction is broken or the internal block is damaged. The solution is to replace and repair.
The eleventh fault phenomenon: the vertical sliding seat rises slowly. The reason is that the vertical sliding seat bearing has no oil or the cylinder piston is worn, and the magnetic collision causes the axis to bend. The solution is to replenish oil, replace the piston command, and adjust the axis.
