Summary:The utility model relates to the technical field of doffing machines, in particular to a PLC automatic control circuit of an intelligent doffing machine, which comprises a PLC, a fifth relay, a sixth relay, a seventh relay, a yarn pulling motor and a spring motor, a Q101.04 of the PLC is connected with a terminal 13 of the fifth relay, a Q101.05 of the PLC is connected with a terminal 13 of the sixth relay, and a Q101.05 of the seventh relay is connected with a terminal 13 of the spring motor. Terminals 11 and 12 of the fifth relay and the sixth relay are connected with two ends of a spring motor; a Q101.06 terminal of the PLC is connected with a terminal 13 of a seventh relay, and a terminal 5 and a terminal 6 of the seventh relay are connected with the two ends of a yarn pulling motor. The problem that a traditional mechanical arm structure is complex in yarn pulling work is solved. The problems that an existing doffer clamps tubes during doffing, and the positioning precision of a single motor of a thread
