Before a machine à couches enters formal production, une inspection complète avant utilisation est essentielle pour garantir des performances stables, minimiser les temps d'arrêt, et améliorer l'efficacité de la production. La procédure de test standardisée suivante, combiné avec le support technique professionnel de Womeng, helps manufacturers achieve a smooth and reliable production startup.
je. Static Inspection
Before powering on the machine, a complete inspection should be carried out to eliminate potential safety risks and identify abnormal equipment conditions.
1. Overall Machine Inspection
Check the general appearance of the machine to ensure there are no loose components, external damage, or unstable structural connections. Key components such as rollers, roulements, and machine frames should be securely connected.
2. Electrical System Inspection
Inspect the electrical system carefully. Ensure that cables are intact, connectors are firmly secured, and the power switch, emergency stop button, and control panel are functioning properly.
3. Mechanical Component Inspection
Verify that all rotating parts are properly lubricated and free from blockage or abnormal resistance. The cutting units, pressure rollers, and conveyor belts should be free of debris or foreign materials.
4. Safety Protection Inspection
Confirm that all safety guards are correctly installed and that safety sensors respond normally without malfunction.
II. Dry Run / No-Load Test
After completing the static inspection, the machine should be tested without loading raw materials to verify the operation of all systems.
1. Power-On and Startup Test
Turn on the power supply and start the machine according to the operating manual. Observe the operating condition of the main motor, transmission system, and control system.
2. Speed Operation Test
Gradually adjust the machine speed from low to high. Ensure stable operation without abnormal noise, vibration, or shaking.
3. Control System Verification
Check whether the touch screen, parameter settings, and automatic control functions such as automatic stop and speed adjustment are operating correctly.
4. Operational Data Recording
Record key operational data including motor speed, noise level, and operating temperature, then compare them with standard machine parameters.
III. Web Threading & Initial Calibration
Load raw materials such as nonwoven fabric, matériaux de base absorbants, and PE film into the machine according to the production process requirements, then perform initial calibration.
1. Material Threading
Thread the materials sequentially through guide rollers, pressure rollers, and cutting stations according to the process route. Ensure that all materials remain flat and properly aligned.
2. Material Tension Adjustment
Adjust the tension of each material layer to ensure uniform feeding without slackness or breakage. All material layers should remain accurately aligned.
3. Initial Parameter Calibration
Set key production parameters such as cutting length, pressing pressure, and folding position according to product specifications, and verify the accuracy of each operation.
4. Feeding Stability Inspection
Ensure that the material feeding speed matches the machine operating speed without material blockage or deviation.
IV. Material-Loaded Trial Production
After calibration, conduct a small-batch trial production using full materials to evaluate machine performance and finished product quality.
1. Trial Production Startup
Operate the machine under full material load according to the preset parameters. The recommended trial production quantity is 50–100 pieces.
2. Product Quality Inspection
Inspect the finished diapers for appearance, dimensions, épaisseur, bonding strength, and absorption performance to ensure compliance with product standards.
3. Equipment Operation Monitoring
Observe whether issues such as material waste, machine blockage, or parameter deviation occur during production.
4. Parameter Optimization
If defects such as uneven thickness or poor bonding appear, adjust relevant parameters including pressure and operating speed until qualified products are achieved.
V. Stabilité & Reliability Test
Long-term operation and extreme-condition testing are necessary to verify machine reliability and continuous production stability.
1. Stability Test
Run the machine continuously under full load for 2–4 hours. Regularly inspect operating conditions, product qualification rates, and equipment temperature.
2. Reliability Test
Simulate extreme working conditions such as maximum speed and long-term continuous operation to evaluate equipment load capacity and fault resistance.
3. Fault Simulation Test
Test emergency stop functions and automatic fault alarm systems to ensure the machine can shut down immediately in abnormal situations and prevent further losses.
4. Post-Test Inspection
After testing, inspect component wear conditions and connection tightness, and resolve any potential issues promptly.
