Daily maintenance of an aluminum foil rewinder focuses on equipment cleaning, lubrication, key system calibration, and safe operation. The following are specific key points and operating procedures:
Equipment Cleaning and Hygiene Management
1. Daily Cleaning
After work, thoroughly clean the equipment surface and parts that come into contact with the aluminum foil (such as guide rollers and winding shafts) to prevent aluminum shavings and dust accumulation that could contaminate or scratch the material.
Clean the glue tank, coating roller, and drying channel to prevent residual glue from solidifying and affecting coating uniformity.
Check that there is no debris between the steel coil and the wool coil to prevent equipment jamming or foil damage.
2. Periodic Deep Cleaning
Clean dust from the transmission system (gears and chains) weekly to ensure smooth operation.
Clean precision components such as tension sensors and photoelectric switches monthly to prevent false triggering.
Lubrication and Transmission System Maintenance
1. Lubrication
Add lubricant (such as butter) to moving parts such as bearings, gears, and chains weekly to ensure adequate lubrication.
Be careful not to drip oil onto the drive belt to prevent slippage and aging.
2. Drive System Inspection
Check the belt and chain tension daily and adjust them to the proper setting to avoid transmission errors.
Tighten all drive components within one week of use for new equipment, and perform regular monthly maintenance thereafter.
Tension Control System Calibration
1. Tension Device Inspection
Test the tension control device (such as the magnetic powder brake and motor torque) daily before starting the machine to ensure stable tension.
Calibrate the tension sensor regularly, maintaining the error within ±2%.
2. Troubleshooting
If the aluminum foil is broken or deformed, immediately check the tension setting and adjust it to the required process range.
Cutting and Embossing Device Maintenance
1. Cutting System Maintenance
Check the cutting blade for wear daily. Replace any dull or damaged blades promptly to ensure a smooth cut edge.
Clean any aluminum foil debris from the blade holder gap to prevent jamming.
2. Embossing Device Optimization
Clean any residue from the embossing roller surface weekly to maintain a clear pattern.
Adjust the contact pressure between the pressure roller and the rear rewind roller to prevent foil deformation.
Electrical and Safety System Inspection
1. Electrical System Maintenance
Monthly check the motor, sensor, and circuit connections to ensure they are not loose, falling off, or overheating.
Keep the electrical control box dry; use a desiccant or dehumidifier to prevent moisture.
2. Safety Device Testing
Weekly test the emergency stop button and protective cover to ensure safe operation.
Check whether the tube pusher trolley limit sensor is blocked by dirt to prevent core tube accumulation.
Rewinding and Unloading System Optimization
1. Rewinding Parameter Adjustment
Set the rewinding tension (generally 40-50 kg/full width) and taper (60%-80%) based on the foil thickness to prevent soft wrinkles or slippage.
Adjust the rewinding pressure to 0.05 MPa to ensure a tight rewind without slippage.
2. Unloading Operation Specifications
Ensure the track is clear during unloading to prevent core tube collision and deformation.
When manually unloading, wear protective gloves to prevent your fingers from being bitten by the take-up shaft.
Regular Calibration and Record Management
1. Monthly Calibration
Perform a comprehensive monthly calibration of the equipment, including parameters such as tension, speed, and temperature, to ensure compliance with process standards.
Check the response speed of each functional module (such as the web correction system and automatic tube loading) and optimize the control program.
2. Maintenance Log
Record each maintenance task, replaced parts, and any problems found to facilitate tracking and planning for the next maintenance task.
Sample Log Format:
| Date | Maintenance Details | Replaced Parts | Abnormal Conditions | Actions |
Operating Specifications and Safety Tips
1. Operator Requirements
Operators must be trained and familiar with the equipment structure and emergency response procedures.
Overload operation is prohibited. Avoid cutting non-metallic materials or carbide.
2. Emergency Response
If aluminum foil breaks, immediately stop the machine to clean the debris and check the tension settings.
If any unusual noise or vibration is detected, immediately stop the machine and inspect the transmission components.
