Granule vertical packing machines are widely used in various industries for packaging granular products such as coffee beans, rice, sugar, and spices. Despite their reliability, these machines can occasionally encounter issues that affect their productivity and efficiency. This article sheds light on several common problems associated with granule vertical packing machines and provides detailed troubleshooting steps to resolve them.

Mechanical Problems

Bag Misalignment: Misaligned bags can result in poor sealing or tearing. Inspect the bag placement system and ensure that the bags are correctly centered before filling. Adjust the bag holders or guiding rails accordingly.

Film Tension Issues: Incorrect film tension can lead to bag wrinkles or tearing. Check the tension settings and adjust them to the recommended values based on the film thickness and product characteristics. Replace the film roll if it appears stretched or deteriorated.

Electrical Problems

Power Failure: In case of a power outage, check the fuse or circuit breaker and reset it if necessary. Ensure that there is no power surge that could damage the machine’s electrical components.

Sensor Malfunction: Sensors play a crucial role in detecting bag presence, film position, and sealing integrity. Inspect the sensors for any dirt or damage and clean or replace them if required. Check the sensor wiring and connectors for proper connections.

Sealing Problems

Poor Sealing: Insufficient sealing pressure or temperature can cause bags to open or leak. Adjust the sealing pressure and temperature settings according to the film material and product requirements. Check the sealing jaws for contamination and clean them if necessary.

Wrinkled Bags: Wrinkled bags indicate excessive film tension or misalignment. Reduce the film tension and ensure that the bags are properly aligned before filling. Adjust the bag clamps to prevent wrinkles during the sealing process.

Bagging Issues

Overfilling: Overfilled bags can break or tear during handling. Adjust the filling system to dispense the desired amount of product into each bag. Calibrate the fill sensor to ensure accurate filling levels.

Bagging Speed Variations: Inconsistent bagging speeds can affect productivity and packaging quality. Check the machine’s motor and drive system for any loose components or worn parts. Adjust the speed settings to optimize performance.

Maintenance Tips

Regular Cleaning: Regular cleaning of the machine’s components, such as the filling system, sealing jaws, and film rollers, is crucial for maintaining optimal performance. Remove any accumulated product residue or film particles to prevent blockages or malfunctions.

Lubrication: Proper lubrication of moving parts, such as gears and bearings, reduces friction and wear. Refer to the manufacturer’s guidelines for the recommended lubrication schedule and use the specified lubricant.

Calibration: Periodic calibration ensures accurate filling, sealing, and cutting operations. Calibrate the machine’s sensors and adjustments according to the manufacturer’s specifications and the specific packaging requirements.
