Powder sachet packing machines are essential pieces of equipment for packaging dry products into single-serving sachets. However, like any machinery, they can experience operational issues that may hinder their productivity. This article aims to provide a comprehensive guide to troubleshooting common problems encountered with powder sachet packing machines.

Feed System Issues

Insufficient Feed

Insufficient feed can result from various factors. Check for blocked feed chutes or lines, as they prevent powder from entering the machine. Additionally, ensure that the powder supply is adequate and that the feed mechanism is properly calibrated.

Powder Bridging

Powder bridging occurs when the powder forms a solid mass that inhibits its flow. This issue can be addressed by implementing anti-bridging measures, such as agitators or vibration systems, to loosen the powder.

Inconsistent Feed Rate

An inconsistent feed rate can cause fluctuations in sachet weight and filling accuracy. Inspect the feed auger or metering device for any damage or misalignment. Recalibrate the system to maintain a steady and consistent flow rate.

Sealing Issues

Leaking Seams

Leaking seams occur when the sachet seals are not properly formed or sealed. This can be due to worn sealing jaws, insufficient heating or pressure, or contaminated seal surfaces. Inspect the sealing mechanism, clean it thoroughly, and adjust the sealing parameters to ensure proper sealing.

Incomplete Seals

Incomplete seals result in open sachets that expose the product to contamination. Check for any obstructions in the sealing area, such as powder residue or debris. Ensure that the sealing temperature and pressure are optimal and that the sealing time is sufficient.

Seal Contamination

Contaminated seals can affect the integrity of the packaging and product. Clean the sealing surfaces frequently to remove any powder residue or foreign matter. Avoid using unsuitable sealing materials or lubrication that may contaminate the seals.

Mechanical Issues

Machine Jams

Machine jams occur when the machine encounters mechanical obstructions. Inspect the machine for any foreign objects or debris that may have gotten in the way. Clear any blockages and ensure that moving parts operate smoothly and without excessive friction.

Belt Breakage

Belt breakage can disrupt the machine’s operation and cause downtime. Regularly inspect the belts for signs of wear, tension, or damage. Replace worn belts to prevent their failure and ensure smooth operation.

Product Contamination

Product contamination can occur due to powder leaks or improper cleaning. Thoroughly clean the machine and its components to remove any residual powder. Implement appropriate measures to prevent powder leaks, such as gaskets or seals.
