Solutions to common faults of automatic screen printing machines

　　There are always various faults in the printing process of the screen printing machine, such as the semi-automatic screen printing machine does not work at all, the power light is on, the printing seat does not work after moving to the left, and so on. The following Guanshentai automation equipment manufacturers will explain to you the common fault solutions of automatic screen printing machines:

　　The first fault phenomenon: the semi-automatic screen printing machine acts immediately without stepping on the foot switch when it is semi-automatic. Most of the reasons for such failures are the damage of the foot switch or the short circuit caused by the water in the foot switch socket, and the other is the problem of the manual start button switch. The repair method is to replace the new switch, socket, push button switch or disassemble and repair related damaged parts.

　　The second kind of failure phenomenon: when the semi-automatic operation is in progress, the foot switch slide goes down, and then goes up again 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 fault phenomenon: when the foot switch is stepped on the vertical slide during semi-automatic operation, the vertical sliding seat will drop, and the printing seat will not move after moving to the left. The reason for this failure is that the proximity switch on the left side of the traverse seat is not sensed or there is a problem. The solution is to adjust the sensing point of the left proximity switch or replace the proximity switch; and the micro switch in the foot switch is stuck and does not work, which will also cause this fault. The solution is to adjust, repair or replace the micro switch inside the foot switch with a new one.

　　The fourth fault phenomenon: when the foot switch is stepped on during semi-automatic operation, the slider moves to the left and then rises but does not move to the right. The occurrence of this phenomenon is that the proximity switch on the upper left of the vertical slide is not sensed or there is a problem with the proximity switch. The solution is to adjust the induction of the proximity switch above or a better proximity switch.

　　The fifth fault phenomenon: after the action is switched, the rising action is half a beat slower. This kind of failure is that the control solenoid valve is blocked by foreign objects or the solenoid valve is faulty. The solution is to remove the solenoid valve to clean or replace the solenoid valve.

　　The sixth fault phenomenon: manual and semi-automatic all do not work, and the power light is on. The reasons for such failures are that the fuse on the low-voltage side is blown, no air source enters, and all the solenoid valves are faulty. The solution is to replace the fuse on the low-voltage side and check whether the pressure reaches 4-7kg/cm.

　　The seventh failure phenomenon: automatic and semi-automatic startup does not drop. This kind of fault occurs when the proximity switch on the right side of the traverse seat is faulty or not sensed, the selector switch is faulty, and the single-action switch interlock point is damaged. The solution is to adjust the proximity switch induction or replace the right proximity switch, and replace or repair the selector switch and single-action switch.

　　The eighth kind of failure phenomenon: automatic can not start. This kind of fault is that the micro switch of the upper and lower cylinders is normally closed, the contact cannot be turned on or the timer is damaged. The solution is to repair the micro switch or replace the timer.

　　The ninth kind of failure phenomenon: the work surface does not inhale, the reason for this kind of failure is that the intake motor is burned. The contactor that controls the operation of the motor is damaged, the suction motor rotates, but the control suction solenoid valve is faulty, and the suction selection switch is faulty. The solution is to repair or replace it.

　　The tenth fault phenomenon: the work surface does not inhale, the reason is that the solenoid valve controlled by the suction station is damaged or the internal block is damaged. The solution is to replace and repair.

　　The eleventh failure phenomenon: the rising speed of the vertical sliding seat is slow. The reason is that the bearing of the vertical sliding seat has no oil or the cylinder piston is worn, and the magnetic impact makes the shaft center bend. The solution is to supply oil, replace the piston password, and adjust the shaft center.
