Capsule weighing scale is an important equipment on the production line of the pharmaceutical industry, used to accurately detect the weight of capsules and ensure that product quality meets standards. However, like all mechanical equipment, capsule weighing scales may experience some common malfunctions during long-term operation. Timely troubleshooting and resolution of these faults are crucial for ensuring production efficiency and product quality. This article will provide you with some common troubleshooting and solutions to help ensure the continuous and stable operation of your equipment.

1、 Inaccurate weighing

（1） Fault performance

The weight displayed in the weighing result does not match the actual weight, and the deviation exceeds the allowable range.

（2） Troubleshooting methods

Calibration check: First, check if the equipment needs to be recalibrated. Long term use or environmental changes may cause deviations in the weighing sensors of the equipment.

Cleaning inspection: Check for residual capsule powder or foreign objects around the scale pan and sensor, which may interfere with the weighing results.

Environmental factors: Check whether the equipment is in stable environmental conditions, avoiding the influence of vibration, airflow, or temperature changes on the weighing results.

（3） Solution

Re calibration: Follow the equipment manual to calibrate and ensure the accuracy of the weighing sensor.

Cleaning equipment: Regularly clean the scale pan and sensors to ensure that there are no foreign objects interfering.

Stable environment: Install the device in a location away from vibration sources and airflow interference to maintain a stable ambient temperature.

2、 Slow device operation speed

（1） Fault performance

The operating speed of the equipment is significantly lower than normal, affecting production efficiency.

（2） Troubleshooting methods

Check for material blockage: Check if there is any blockage in the capsule conveying channel, as blockage can cause a decrease in equipment operating speed.

Check motor performance: Check if the motor is working properly. Motor failure or overload may cause the operating speed to slow down.

Check the control system: Check if there are any malfunctions in the control system of the equipment. Problems with the control system may cause the equipment to operate abnormally.

（3） Solution

Clearing blockages: Timely clean the capsule conveying channel to ensure smooth passage of materials.

Check the motor: Check if the motor needs to be repaired or replaced to ensure its normal operation.

Check the control system: Contact equipment suppliers or professional technicians to inspect and maintain the control system.

3、 Frequent shutdown alarm

（1） Fault performance

The equipment frequently experiences shutdown alarms during operation, which affects production continuity.

（2） Troubleshooting methods

Check sensors: Check if the weighing sensor, photoelectric sensor, etc. are working properly. Sensor failures may cause false alarms.

Check material supply: Check if the supply of capsules is stable, as unstable material supply may cause equipment misjudgment.

Check alarm settings: Check if the alarm threshold of the device is set reasonably. Unreasonable alarm thresholds may lead to frequent alarms.

（3） Solution

Repair or replace sensors: Repair or replace faulty sensors to ensure they are functioning properly.

Stable material supply: Optimize the capsule supply system to ensure the stability of material supply.

Adjust alarm settings: Adjust the alarm threshold reasonably according to the actual production situation to avoid false alarms.

4、 Tips for ensuring continuous and stable operation

（1） Regular maintenance

Regularly maintain the equipment, including cleaning, calibrating, and inspecting key components, to ensure that the equipment is in good condition.

（2） Operation training

Ensure that operators are familiar with the operating procedures of the equipment and common troubleshooting methods to avoid equipment failures caused by improper operation.

（3） Spare parts preparation

Prepare some commonly used spare parts in advance, such as sensors, motors, etc., so that they can be replaced in a timely manner in case of equipment failure, reducing downtime.

（4） Technical support

Establish contact with equipment suppliers or professional technicians to obtain timely technical support when encountering complex faults.

V. Summary

The stable operation of capsule weighing scales is crucial for ensuring the quality and production efficiency of capsule products. By promptly troubleshooting and resolving common faults, equipment downtime can be effectively reduced and production efficiency can be improved. Regular maintenance, operation training, spare parts preparation, and technical support are key to ensuring the continuous and stable operation of equipment.
