Common faults and troubleshooting of plastic cup sealing machine

Common faults and solutions:
1： The indicator light is not on
reason:
1. No AC voltage input
2. Indicator light is damaged
Troubleshooting:
1. External power reconnection
2. Replace the indicator light
2： The whole machine does not run
reason:
1. Unreliable wiring
2. The motor switch is damaged
Troubleshooting:
Tighten the screws of each terminal and replace them
3： The seal is not firm
reason:
1. Temperature too low
Troubleshooting:
1. Heat up properly until it is sealed tightly
4： Unclean slitting
reason:
1. The temperature is too high or too low
2. Slitting ring deflection
Troubleshooting:
Adjust the temperature properly
Conduct sealing and thickening again
5： No temperature rise
reason:
1. Burnout of temperature rise switch
2. The electric heating tube is burnt out
3. Temperature controller failure
4. Thermal power meets open circuit
Troubleshooting:
Replace the switch
Replace the electric heating pipe
Repair or replace the temperature controller
Replace the mature thermocouple
6： Insufficient or excessive filling
Cause: eccentric displacement of metering regulator
Troubleshooting:
Readjust the metering regulator
7： Free oxygen during filling
Cause: poor sealing between water pump and water pipe
Troubleshooting: check whether the seals of the water pump are in good condition
Whether the pipe seat is tightly connected is eliminated
8： Unclear printing
Cause: high or low temperature
Troubleshooting: Adjust the temperature of the printer to remove font stains
