What is the cause of the winding machine turntable not turning?

When the film winding machine is in use, sometimes the turntable does not turn. How do we solve this situation?

First, check the chain of the inverter, adjust the distance between the large and small sprocket, and then re-link the connection.
Second, the rotary reducer itself has a problem of failure. At this time, it is only necessary to perform better on the reducer.
Third, check the inverter of the film winding machine. When it does not show any display, it means it is burned out, and it is necessary to make a timely replacement. If the setting of the parameter is wrong, just re-set it according to the requirements of the technical department.
