Wire rod jamming prevention device for 3D additive manufacturing production line

The invention relates to the technical field of additive manufacturing, in particular to a wire rod jamming prevention device for a 3D additive manufacturing production line. The wire rod jamming prevention device comprises a motor and a tension induction control part, wherein an output shaft of the motor is connected with a wire rod disc through a one-way bearing. The tension induction control part comprises a wire rod transition part and a power switch, wherein the power switch controls on-off of the motor, and the wire rod transition part is located between the wire rod disc and a 3D printer. Wire rods on the wire rod disc bypass the wire rod transition part from the lower side of the wire rod transition part and then enter a feeding port of the 3D printer, the power switch is located on the lower side of the wire rod transition part, when the wire rods can be fed normally, the motor does not work, the wire rods drive the wire rod disc to rotate, when the wire rods are clamped, themotor works to drive the
