The double-acting telescopic cylinder 107 acts to drive the positioning clamping plate 101 to clamp and fix the wire 600. The printing drive motor drives the printing tape 103 to move longitudinally. The lifting cylinder 104 drives the two heated printing blocks 102 to press onto the wire 600 to complete printing; after the printing operation is completed, the lifting cylinder 104 drives the two printing blocks 102 to move away from each other. The first driving wheel 301 of the main wire guiding mechanism 300 pulls the wire 600 to move laterally for the second time. The lateral conveying dimension of the wire 600 is calculated by the encoder 201, and the air cylinder drives the upper cutting knife 401 and the lower cutting knife 402 to press together to complete the slitting process.
