The invention discloses an automatically adjusted line pressing wheel device and belongs to the field of metal manufacturing equipment. The device comprises a line pressing wheel, a bearing, a universal bearing and an elastic supporting structure, wherein limiting baffles are fixed at two ends of the line pressing wheel, and a limiting separator is fixedly arranged in the middle of the line pressing wheel; one end of a rotating shaft of the line pressing wheel is fixedly connected with a universal joint shaft; the universal joint shaft is connected with a driving motor; the elastic supporting structure comprises a supporting seat, a spring, a telescopic mechanism and a fixing rack; and the telescopic mechanism comprises a loop bar and a sleeve. According to the device disclosed by the invention, a phenomenon that a soft state alloy wire rod is scratched, collided or pressed to generate indentation can be avoided, the line pressing wheel device is applied to line pressing of soft-state alloy materials such as H65 materials, the materials can be recycled, the service life is long, the use rate of the line pressing wheel can be improved, and balanced tensioning degree of the wire rods in the high-speed transfer process is guaranteed, so that the phenomenon that a gold thread is severely pulled even broken is avoided.
