Screen printing machine is broken how to do: screen printing machine breakdown Troubleshooting


By screen printing machine is the solder paste or glue were missing patches to a device on the PCB pads. Mainly used in electronic processing industry, printed circuit board silkscreen logo, instrument panel housing a sign board processing of solder paste printing. Screen printing machine in the printing process will always exist various kinds of failure, such as manual, semi-automatic, all without action, power light, print seat left after no action and so on. End of the year-end, in the screen printing machine production and marketing enterprises are busy preparing many presumably recover the balance due home for the holiday, right? So, if you sell printing machines but always fails when the customer rush production, do you think the customer will be happy to give you money? Around eleven screen printing machine Common Faults, causes and solutions analysis following small for everyone.
First Symptom: When semiautomatic not step on the pedal and immediate action.
Failure of such damage is mostly a foot switch or foot switches and sockets cause a short circuit caused by water, and the other is a manual start button switch problem. The fix is ??to replace the switches, sockets, buttons, switches or open repair damaged parts related.
The second Symptom: semi-automatic screen printing machine work step on the pedal when the carriage drops, release and then rise.
This phenomenon is generally horizontal slide the left proximity switch is damaged or broken wires, the solution is to replace the proximity switch or turning on the switch connection.
The third Symptom: When semi-automatic screen printing machine work step on the pedal carriage stand down after printing the seat does not move to the left.
The reason for this failure has cross-slide to the left or inductive proximity switch is not a problem.
The solution is well on the left to adjust the proximity switch sensing point or replace good proximity switch; there are micro switch stuck within a foot switch does not move, can also cause this problem. The workaround is to adjust the micro switch inside foot switch, repair or replacement of the micro switch.
The fourth Symptom: When semiautomatic working step on the pedal, the carriage fell after rising to the left, but not right.
This phenomenon is the legislature of the carriage to the upper left of proximity switches or inductive proximity switch is not a problem, the solution is to adjust the upper proximity switch inductive proximity switches or better.
Fifth Symptom: screen printing machine movements after switching rise belated action.
Such failures are printing machine control solenoid valve of a foreign body obstruction or faulty solenoid valve, the solution is to dismantle and clean or replace the solenoid valve solenoid good.
Sixth Symptom: manual, semi-automatic, all without action, power light.
Such causes are the low-pressure side of the screen printing machine fuse, no air enters, solenoid valves all have faults. The solution is to change the low-pressure side fuse, check whether the pressure of 4-7kg / cm, the solenoid-all fault is very small, mostly broken wires.
Seventh Symptom: automatic, semi-self-starting does not drop.
Such failure is a right side cross slide proximity switch is faulty or not sensed, the selector switch failure, single-action switch linkage point is damaged. The workaround is to adjust or replace the right side inductive proximity switch proximity switch, replace or repair the selector switch and single switch.
Eighth Symptom: Can not start automatically.
Such failures are the upper and lower cylinder screen printing machine supporting micro switch normally closed contacts can not be turned on or timer damaged, the solution is to fix the micro switch, or replace the good timer.
Ninth Symptom: screen printing machine work surface is not breathing, such failure because the suction motor burned.
Control operation of the motor contactor damage, suction motor rotates, but the control intake solenoid valve failure, breathing select switch failure, the solution is to repair or replace.
Tenth seed Symptom: The worksurface not inhale.
The reason is that the suction solenoid valve is broken or damaged internal control block, the solution is to replace repair.
Eleventh Symptom: Li carriage rise slowly.
The reason is that Li carriage bearing no oil or cylinder piston wear make axial bending magnetic collision, the solution is to supply the oil, replace the piston password, adjust the axis.
