Automatic filling machine common failure and maintenance
Automatic filling machine can automatically fill products, although the degree of automation is high, but in the process of use, there may be some failures, common failures and solutions are mainly.
Fault 1: The accuracy error in the filling process is large
1, the generation of filling error is mainly determined by the filling amount, filling speed, and the switching speed of the upper and lower valves. The switching speed of the upper and lower valves is related to the viscosity of the product, and the greater the viscosity, the slower the valve switching speed.
2, the liquid filling machine to adjust the pressure of the valve should be determined by the test filling measurement and the experience of the operator
3, adjust the valve switching speed, mainly adjust the valve projectile pressure, projectile pressure increases, then the valve switching speed increases.
Fault two: The liquid filling machine does not react when starting and cannot work normally
Check the fuse. 1, turn off the power first, check whether it is a line problem,
2, release the emergency stop button, and then start the machine again
3. Check whether there is power supply in the switching power supply.
4, check whether the mechanical touch screen and PLC communication line is connected.
Fault 3: Liquid filling machine material can not be filled
1. Check whether the feed nozzle is closed and restart the machine.
2. Check whether the air pressure is normal, and whether the injection cylinder and cylinder leak
3, the material reaches a low limit, not enough to fill the corresponding container
Fault 4: Insufficient filling of the tank, resulting in unstable liquid level
1, can increase the amount of feed or re-close the valve.
2. Reset the filling time (lengthen the filling time) and slow down the filling speed to solve fault 5: drip after closing and stopping the filling
1. The orifice of the feeding nozzle may be damaged, so it is advisable to trim the orifice of the feeding nozzle, and the diameter of the orifice shall not be greater than 7.5mm.
2. After repairing the aperture, gently smooth the door plane on the water abrasive sandpaper.
Second, what are the reasons for the failure of the automatic filling machine
There are many reasons for the failure of the automatic filling machine, which can be roughly divided into the following three categories:
1, automatic filling machine itself
It may be that the enterprise did not choose a filling machine manufacturer with relatively good product quality when purchasing equipment. Mechanical equipment such as automatic filling machines require sufficient strength and strong fatigue resistance to the production material. If the equipment purchased by the enterprise is due to the insufficient strength of the equipment material and poor fatigue resistance, it will lead to the filling machine aging quickly, and it is easy to wear and tear leading to the failure of the filling machine
2. Reasons for improper operation
Because of improper operation, insufficient daily maintenance, and poor equipment use environment, these may cause the failure of the filling machine.
3. Causes of environmental impact
Damp air, dust and other factors will affect the normal production of precision machinery such as filling machine, these factors will cause the decline in the operating state of the filling machine, resulting in the loss of parts of the filling machine, so that the life of the filling machine is greatly reduced.
