The invention discloses a petrifaction residual oil filter element production device. The petrifaction residual oil filter element production device comprises a base, a welding device, a traction device and a straightening device. The welding device is used for keeping the welded state of main reinforcements and metal wires. The traction device carries out traction rotation on the main reinforcements according to the set linear traction speed and the rotation speed. The straightening device is used for carrying out on-line straightening on the coiled metal wires. A guiding device used for slightly regulating the state of the metal wires is further arranged between the straightening device and the welding device. The petrifaction residual oil filter element production device is used for producing high-precision filter screens, the state of the main reinforcements and the metal wires forming one filter screen can be accurately controlled in the production process, the production qualityof the filter screens is guaranteed, and the device is easy to operate, good in stability and high in production efficiency.
