1. Bag slippage:

Replace or clean the pressure valve. If the pressure air path is blocked, straighten and clear it.

 

2. Uneven or non-sealing:

Adjust the heating time and temperature. Clean and replace the heating cloth immediately if there are any deposits. Replace the air bladder immediately if it is damaged.

 

3. Vacuum pump oil leakage:

If the vacuum pump is leaking oil, remove the return valve and clean it. If the oil window is loose, remove it and wrap it with Teflon tape or film.

 

4. Excessive noise during vacuuming:

Excessive noise during vacuuming can affect the working environment.

 

5. Heating not stopping:

Immediately adjust or replace the time relay and socket contact. If the heating AC contactor does not reset, repair or replace it immediately.

 

6. Low vacuum level in vacuum packaging machine:

This situation is detrimental to food freshness. Therefore, we need to clean the vacuum pump, change the vacuum pump oil, clean or replace the exhaust filter, and if there is a leak, turn off the power after vacuuming.

 

 

Pre-made bag packaging machines consist of standard components such as a coding machine, PLC control system, dust removal device, solenoid valve, temperature controller, vacuum generator or vacuum pump, frequency converter, and output system.

 

The above problems are common in pre-made bag packaging machines; we can resolve them promptly when they occur.
