Troubleshooting Common Issues with Multihead Weighers: Solutions and Expert Support from Kenwei
This article outlines frequent problems encountered in multihead weighers, such as vibration leakage, motor reset failures, and weighing inaccuracies. Learn Kenwei’s expert solutions and how our technical team ensures reliable performance with a two-year warranty.
As a leader in intelligent weighing and packaging solutions, Guangdong Kenwei Intellectualized Machinery Co., Ltd. offers reliable support for issues encountered in the operation of multihead weighers. Below, we outline common customer concerns and provide expert recommendations to help ensure your equipment runs efficiently and accurately.
1. Material Leakage from Vibration Plate
Issue:
Customers reported material accumulation beneath the vibration plate, caused by leakage.
Possible Cause:
The flat design of the linear vibration plate may not be suitable for the current material type.
Solution:
-
Upgrade to a concave vibration plate to reduce leakage.
-
Cover the end of the online vibration plate with a hygienic plastic guard before installing the main plate. This helps prevent material buildup and leakage.
2. Motor Fails to Reset
Possible Causes & Checks:
-
Photoelectric sensor failure – Hopper door opens three times in succession.
-
Damaged detection disk – Check by removing the aluminum box.
-
Misalignment – Ensure the sensor notch aligns with the motor bearing.
-
Mainboard malfunction – Test manually by grounding the motor signal pin. If it stops normally, the mainboard is functional.
3. Accuracy Drops at 40 Bags/Min Speed
Observation:
Performance is stable at low speeds but fluctuates at higher speeds.
Cause:
Incorrect parameter settings rather than hardware failure.
Recommended Settings:
-
Sampling stabilization time: 80
-
Filter coefficient: 6
These settings help maintain consistent weighing accuracy even at higher speeds.
4. Weak Weighing Buckets with Noise
Potential Causes:
-
Faulty drive boards.
-
Mainboard circuit failure.
-
Unstable drive board voltage.
Diagnostic Steps:
-
Swap control cables between storage and weighing hoppers.
-
Test manually to check if mainboard is faulty.
-
Measure voltage between D011 and D012 (should be AC24V).
5. Empty Bags Due to Missed Combination Signal
Problem:
When using a collecting hopper and relying on the "ready" signal from the weigher, the packaging machine may trigger too early, resulting in empty bags.
Cause:
The packaging machine receives the signal before new material has arrived due to the timing delay between the collecting hopper discharge and the next combination.
Solution:
Adjust the synchronization signal so the packaging machine only activates once new material is confirmed.
