NOVELTY - The invention claims a spray head of graphene RFID antenna manufacturing device, comprising a cylindrical shell and an anti-blocking mechanism. the cylindrical shell is provided with a slurry channel passing through the cylindrical shell, the slurry channel comprises an inlet hole, an outlet hole and a first channel connected with the inlet hole and the outlet hole; the anti-blocking mechanism comprises an impact disc, a working column and a spring, an impact disc, a working column, the spring is set in the first channel, the impact disc, the axial direction of the working column and the first channel are the same, the impact disc is opposite to the inlet hole, the impact disc is connected with the working column, the spring is sleeved on the working column, one end of the spring is connected with the cylindrical shell, the spring can make the impact disc located at the first position, along the axial direction of the first channel, the direction close to the outlet hole is the extending direction of the working column, The impact disc is capable of receiving impact from the slurry entering from the through hole, so as to move along the axial direction of the first channel, so as to leave the first position, so that the working column extends to the outer boundary, so that the working column discharges the solidified slurry discharge nozzle.
