There are many different types of offset printing machines. According to different usage characteristics, it can be divided into flat offset printing machines and curved offset printing machines, etc., according to different use effects, it can be divided into curved screen printing machines and the like. Each type has its own advantages. Then the offset printing machine malfunctions in daily use, how should it be ruled out?

Offset printing machine troubleshooting method:

1. When the motor is semi-automatic, it does not step on the foot switch and immediately moves. Most of the causes of such failures are caused by damage to the foot switch or short circuit caused by the water in the foot switch socket, and the other is a problem with the manual start button switch. The repair method is to replace the new switch, socket, push button switch or disassemble the repair related damage parts.

2. When the semi-automatic work is performed, the foot switch slides down, and then rises after being released. This phenomenon is generally caused by damage or disconnection of the proximity switch on the left side of the cross slide. The solution is to replace the proximity switch or connect the switch.

3. When the semi-automatic work is done, the foot switch is stepped on, and the slide is lowered to the left and then rises but not moved to the right. This phenomenon occurs when the proximity switch on the upper left side of the vertical slide is not sensed or the proximity switch has a problem. The solution is to adjust the proximity proximity switch to sense or better the proximity switch.

4. After the action is switched, the rising action is slow and half beat. Such a fault is to control the solenoid valve to block foreign matter or the solenoid valve is faulty. The solution is to remove the solenoid valve to clean or replace the solenoid valve.

5, manual, semi-automatic all do not move, the power light is on. The cause of such failure is that the low-voltage side fuse is blown, no air source is entered, and all the solenoid valves are faulty. The solution is to change the low-voltage side fuse to check whether the pressure reaches 4-7kg/cm. The solenoid valve has all the faults, and most of them are disconnected.
