Xilin bottle integrated machineWidely used in industries such as pharmaceuticals and biological products, it integrates multiple functions such as bottle washing, drying, filling, plugging, and capping, achieving automated production of drug packaging. However, during long-term operation, the equipment may experience various malfunctions, affecting production efficiency and product quality. Mastering the troubleshooting and repair methods for common faults is the key to ensuring the stable operation of equipment.

1、 The device cannot start or automatically shuts down

Possible reasons:

Abnormal power supply or blown fuse;

The emergency stop button is not reset or the safety door is not closed;

Control system program error or PLC module failure;

Insufficient gas source pressure or blocked gas path.

Handling method:

Check whether the main power supply and various circuit connections are normal, and replace damaged fuses;

Confirm that the emergency stop button is reset, the safety door is closed, and the limit switch is triggered;

Restart the control system and, if necessary, restore factory settings or upgrade software;

Check the working status of the air compressor, clean the filter, and ensure that the air pressure is within the set range (usually 0.4-0.6MPa).

2、 Unclean bottle washing or residual water droplets

Possible reasons:

Insufficient cleaning water pressure or nozzle blockage;

The drying temperature has not reached the set value;

Insufficient bottle transportation leads to insufficient cleaning time;

Dirty filters affect water quality.

Handling method:

Check the working status of the water pump and adjust the water pressure to the standard range;

Clean the nozzle to ensure unobstructed water flow;

Calibrate the heating device to ensure that the temperature in the drying section is maintained above 120 ℃;

Replace or clean the filter to improve the cleanliness of the cleaning water.

3、 Inaccurate filling volume or dripping phenomenon

Possible reasons:

The accuracy of the metering pump decreases or the internal sealing ring ages;

The filling needle is not aligned with the bottle mouth or the lifting mechanism is stuck;

Excessive filling speed leads to liquid reflux;

Bubbles in the pipeline affect the stability of measurement.

Handling method:

Calibrate or replace the metering pump, check the wear of the sealing ring;

Adjust the position of the filling head, clean the guide rail, and lubricate the lifting components;

Reduce the filling speed or use a "slow closing" method to minimize dripping;

Remove air from the pipeline to ensure stable liquid delivery.

4、 Failed to add or deformed plug

Possible reasons:

The feeding of the plug vibration disc is not smooth or the plug separator is misaligned;

Improper adjustment of the stroke of the compression cylinder;

The plug size does not match or becomes soft due to moisture;

The wear of the guide sleeve causes the plug to shift.

Handling method:

Clean the vibration disc channel and adjust the angle of the plug separator;

Calibrate the cylinder stroke to ensure that the pressure plug force is moderate;

Replace the plug with a suitable specification and keep the storage environment dry;

Replace the guide kit and ensure that the plug falls vertically.

5、 Poor rolling or deformation of aluminum cover

Possible reasons:

Wear of the rolling blade or improper adjustment of the gap;

Inconsistent height of bottle mouth leads to uneven capping;

The aluminum cover does not meet the specifications or the material is too hard;

Loose transmission chain affects synchronicity.

Handling method:

Replace the rolling blade or readjust the gap;

Check the height of the bottle conveying platform to ensure consistency;

Use aluminum cover materials that meet the standards;

Tighten the transmission chain to ensure synchronous operation of each workstation.

　　Xilin bottle integrated machineAs the core equipment on the pharmaceutical packaging line, its operational stability directly affects production efficiency and product qualification rate. Through scientific investigation and timely repair of common faults, not only can the service life of equipment be extended, but production quality can also be effectively improved. It is recommended that enterprises establish a comprehensive maintenance system, regularly calibrate key components, train operators, and ensure that equipment is always in good operating condition.
