Analysis and treatment of common six major failures of three-in-one filling machine
The three-in-one filling machine is an automatic, high-efficiency, high-quality filling equipment, which is very important in the whole packaging machine market. If the equipment is used, it will not be dealt with in time, and the loss caused by the enterprise. It is also obvious. Here is a brief introduction to how the three-in-one filling machine has several problems:
The filling amount of the one-and three-in-one filling machine is not allowed: when the three-in-one filling machine is filled with large specifications, the feeding of the trough is insufficient, resulting in unstable liquid level, which can increase the feeding amount or re-close the small irrigation. The ball valve above the material head, reset the filling time of the three-in-one filling machine (longer filling time) to slow down the filling speed of the three-in-one filling machine to solve.
Second, after adjusting the digital dialing code or unit, the time does not change. At this time, turn off the power and then turn on the power again.
Third, the liquid level is stable, the filling volume of the three-in-one filling machine is not accurate: there is a debris filling three-in-one filling machine filling channel, mainly in the inlet of the trough or in the filling nozzle, check and clean up .
4. There is a drip after closing:
1. If the orifice of the filling nozzle is damaged, the filling nozzle can be taken out and the diameter of the orifice can not be larger than 7.5mm. After fixing the hole diameter, gently smooth the orifice plane on the water sandpaper.
2. The ball valve in the filling head of the three-in-one filling machine is damaged, and the ball valve needs to be replaced.
5. Do not fill after touching the injection switch. The digital indicator of the time relay indicates that the LED does not flash: the injection switch is damaged or the time relay base is loose. Replace the same type of injection switch or press the time relay base.
6. After touching the injection switch, the time relay digital LED indicator flashes, but does not fill: first check if there is no air pressure or the air pressure is too low, such as the air pressure meets the requirements (4-6Kg/cm2), it may be a solenoid valve If the coil is damaged or the pneumatic valve core is stuck by the dirt, you can unplug the power supply, open the board, use the object to rotate or press the button next to the corresponding solenoid valve coil. If the valve can reverse the action, it means the solenoid valve coil is damaged. In the case of reversing, the valve spool is stuck, and the solenoid valve coil or the disassembling valve can be replaced for repair (requires an electrician or a person with pneumatic knowledge to disassemble or inspect).
