Ultrasonic detection and maintenance methods for paper cup machine welding

To check electrical faults based on the presence or absence of sparks, size and other phenomena. For example, when sparks are found between normally tightened wires and screws, it means that the wire ends are loose or in poor contact. When the contacts of the electrical appliance are closed or disconnected, sparks indicate that the circuit is connected, and no sparks indicate that the circuit is not connected. Action procedure: The action procedure of the electrical appliance should comply with the requirements of the electrical manual and drawings. If an electrical appliance on a circuit acts too early, too late or does not act, it means that the circuit or appliance has a fault.

In addition, the fault of the paper cup machine can also be analyzed and judged based on the sound, temperature, pressure, smell, etc. emitted by the electrical appliance. Using the intuitive method, not only can simple faults be determined, but more complex faults can also be reduced to a smaller range.
