In most of the operation of the use of screen printing machine customer feedback, sometimes the screen printing machine out of a small problem on the urgent call, often they can solve the problem in three or two minutes. By the time they do, it takes too long. In fact, it is better to teach people to fish than to give them fish. Instead of worrying themselves every time there is a problem, I think what we need more is to be able to solve some small problems by ourselves. Here are some common faults and solutions for screen printing machines!

Common screen printing machine faults and troubleshooting methods

1. The screen printing machine starts immediately without stepping on the screen printing machine foot switch when opening the semi-automatic, and the main reasons for such failures are mostly because the foot switch is damaged or the foot switch socket has water, resulting in short-term short circuit caused by such a failure. In addition, there may be a problem with the manual open button switch, and the repair method is to replace the new manual open switch or socket or button switch, or remove the open switch to repair the relevant damaged parts.

2. When the screen printing machine works in the semi-automatic working state, the foot switch slide drops, and the phenomenon rises after releasing the foot. This kind of fault is generally the switch on the left side of the slide block is damaged or the connection line is broken, the solution is to replace the switch or switch the connection line.

3. When the screen printing machine opens the semi-automatic working state, step on the foot switch and drop the slide seat, and the printing seat does not move after moving left. The reason for this failure is that the approach switch on the left side of the transverse slide seat is not sensed or there is a problem. The way to solve the problem is to adjust the left switch sensing point or change the proximity switch; In addition, the foot switch is stuck and does not act, which is caused by the fault. The solution is to adjust the switch in the foot switch, repair the micro switch or replace it.

4. The screen printing machine moves half a beat slowly when it rises the lift plate after the action change. This kind of fault as long as there is something blocking the control solenoid valve or the solenoid valve is faulty, the solution is to replace the solenoid valve or repair it.

5. All manual and semi-automatic actions do not respond but the power light is on. The general reason for this kind of failure is that the low-voltage side fuse is burned and no air source enters, and the solenoid valve is all faulty. The solution to the problem is to replace the low pressure side fuse, check whether the pressure reaches 4-6P, in this case, the possibility of all the solenoid valves failing is very small, most of them are broken.

6, automatic or semi-automatic does not fall. The reason for this kind of problem is because the right approach switch of the transverse slide is faulty or not sensed, and the connection point of the single acting switch may be damaged. Fix the problem or replace the right proximity switch to adjust the proximity switch sensing.

7, the automatic function of the screen printing machine can not start, the fault is because the micro-branch switch of the upper and lower cylinder is normally closed, the contact can not be switched on or the timer is damaged, the solution is to repair the switch, or change the timer.

8, screen printing table does not inhale. This kind of fault is that the suction motor is burned, or the contactor that controls the operation of the motor is damaged, the control suction solenoid valve is faulty, and the suction selection switch is faulty. The solution is to repair the circuit or replace the corresponding parts.

9, screen printing machine vertical slide rising speed is relatively slow, the reason is that its bearing no oil or cylinder piston itself wear, magnetic impact to bend the axis, the solution is to supply oil, replace the piston, adjust the axis position.
