This application relates to the field of wire manufacturing technology, and particularly to a pressure roller device for multiple rows of wires. A support roller is installed below the wire conveying path, and several positioning plates are installed on one side of a mounting plate. One end of the support roller and pressure roller extends through a connecting shaft that passes through the mounting plate. Locking components are installed on the connecting shaft to fix the support roller and pressure roller, thereby detachably fixing the support roller and pressure roller to the mounting plate. Several pressure rollers are distributed above and below the wire conveying path and on both sides of the support roller. The support rollers support the wires, preventing them from sagging and deforming during conveying. Several annular grooves are formed on the surface of each pressure roller for power lines to pass through. During conveying, the annular grooves of the pressure roller limit the movement of multiple rows of wires, preventing them from shifting or deforming during transport, thus improving the quality of wire production.
