Maintenance Methods for an Electromagnetic Induction Sealing Machine

Systematic maintenance is essential to effectively extend the equipment’s lifespan and ensure consistent sealing quality. Today, we’ll walk through key maintenance methods for electromagnetic induction sealing machines, summarized as follows:

I. Daily Cleaning Guidelines

1. Cleaning the Machine Surface

After turning off the power and allowing the machine to cool, wipe the work surface, base plate, sliding plate, and grooves with a soft cloth to prevent residue from corroding the equipment.
When cleaning the toothed knife, plug the drainage hole with cotton, pour in hot water, and flush repeatedly to remove dirt.
After each use, clean the control panel and sealing wire surface to remove any contaminants.

2. Induction Head Maintenance

Regularly inspect the white Bakelite panel at the front of the induction head. If it appears scorched or discolored, disassemble and check the condition of the coil insulation.
Clear any accumulated dust inside the sealing chamber to ensure the gap between the induction head and the aluminum foil remains around 4mm.

II. Lubrication and Mechanical Component Maintenance

1. Lubricating the Transmission System

Every 48 hours, apply No. 6 machine oil or grease to the gears, bearings, and guide rails to maintain smooth operation.
Pay special attention to lubricating the lower mold sliding plate, pressure rod bearings, and the eccentric guide post.

2. Cooling System Maintenance

Check the coolant level weekly and replenish with non-conductive coolant as needed. To prevent freezing in the pipes, antifreeze can be added.
Before shutting down the machine, turn on the cooling fan to reduce temperature and avoid prolonged exposure to high heat.

III. Environment and Equipment Status Management

1. Operating Environment Control

The machine should be placed in a well-ventilated, dry area. A room temperature of around 25°C is recommended. Avoid positioning it on metal tables to prevent electromagnetic interference.
If the machine is not used for an extended period, cover it with a dust cover and keep the power turned off.

2. Periodic Inspection Items

Check the parallel alignment of the conveyor belt daily (tolerance ≤ 0.6mm) as well as the height of the induction head.
Clean the lower mold groove, photoelectric sensors, and micro-switches weekly to prevent contamination from affecting induction accuracy.
Regularly inspect power cables for exposed wires and repair or replace them promptly.

IV. Special Operational Precautions

1. Temperature Control

Monitor the temperature rise of the induction head during operation. If it exceeds 80°C, pause operation and cool down before restarting.
The machine is equipped with an overheat protection function. If the indicator light turns on, stop operation and allow the unit to cool.

2. Emergency Fault Handling

If sealing is incomplete, first check the bottle mouth’s flatness, aluminum foil alignment, and whether heating power is appropriately matched.
In case of abnormal noise or exposed wiring, immediately shut down the machine for inspection and repair.

V. Safety Guidelines

1. Always power off the machine before performing maintenance. Never open the housing while the power is on.

2. Use a grounded three-wire power source, and wear protective gear to avoid contact with high-temperature components.
