Ruizhi Machinery: Troubleshooting and Solutions for Glue Spreader Roller Not Rotating
Maintenance Tips | April 27, 2025 | Views: 33
During equipment operation, the glue spreader roller serves as a critical transmission component, and its stable operation directly affects production efficiency and product quality. When the glue spreader roller stops rotating, a systematic inspection is required to quickly identify the root cause. Below is a comprehensive troubleshooting guide designed to help you swiftly locate issues and take effective actions when faced with a glue spreader roller malfunction.
1. Mechanical Jamming If the glue spreader roller is completely stationary, first inspect the mechanical transmission system for physical obstructions. Pay special attention to the gear engagement, bearing lubrication condition, and tension of the transmission belt. After removing entangled debris, thoroughly clean the gearbox and replenish it with specialized lubricating grease. We recommend regularly maintaining transmission components and proactively replacing heavily worn bearings or gears.
2. Motor Failure After verifying that there is no mechanical obstruction, check the drive motor's operating status. Use a multimeter to measure the input voltage at the motor terminals to ensure normal three-phase power supply. Inspect the status of circuit breakers, contactors, and thermal relays inside the control cabinet, paying close attention to any oxidation or looseness at the power cable connection terminals. For motors controlled by frequency converters (inverters), verify frequency setting parameters and review fault codes.
3. Gearbox Connection Issues If the motor operates normally under no-load conditions but the glue spreader roller still does not rotate, focus on inspecting the gearbox transmission linkage. Disconnect the power connection and manually rotate the one-way bearing and gears to confirm smooth internal gear movement. Check the coupling cushion pads; replace immediately if damaged.
4. Motor Phase Loss When the motor emits an abnormal humming noise and fails to start, phase loss is highly likely. Use a clamp meter to measure the three-phase current balance to determine if there is a phase loss in the power supply. Inspect distribution circuit connections for loose joints, blown fuses, or burned contactor contacts. Special reminder: prolonged operation under phase loss conditions will cause overheating and damage to motor windings. Immediately stop operation for inspection if this issue is identified.
5. Further Technical Support While we have provided a detailed troubleshooting guide, you may encounter complex or difficult-to-resolve issues in actual operation. In such cases, please do not hesitate to contact our technical support team immediately. Our professional engineers will offer further diagnostics and solutions to ensure your equipment quickly returns to normal operation, preventing extended downtime and production losses.
