The utility model relates to an anti-static device for a stainless steel wire. The anti-static device comprises a shell, a cylinder, a winding drum, a pull rope and a balancing weight, the cylinder is fixedly installed in the shell, and a through hole coaxial with the cylinder is formed in the shell so that the stainless steel wire can penetrate through the cylinder. One end of the winding drum extends into the shell, and the winding drum is coaxially and rotatably mounted on the cylinder; one end of the pull rope is fixedly mounted on the winding drum, and the other end of the pull rope penetrates through the shell in a sliding manner; the balancing weight is fixedly installed at the end, away from the winding drum, of the pull rope. The cylinder, the winding roller, the pull rope and the balancing weight are all conductive. A steel wire is inserted into a cylinder through a through hole, and under the action of gravity, a balancing weight pulls a pull rope wound on a winding drum to extend, so that the balancing weight abuts against the ground; and the inner side wall of the cylinder is in contact with the stainless steel wire, so that the electrostatic current on the stainless steel wire is conducted to the bottom surface through the cylinder, the winding roller, the pull rope and the balancing weight in sequence, and the electrostatic current on the stainless steel wire can be effectively reduced.

The utility model discloses an encoder transmission mechanism, which belongs to the technical field of detection and transmission, and solves the problem of elongation measurement interruption caused by slight vibration or slight displacement of two stretching heads in the working process of the original tension straightening machine. A sleeve hole is formed in the protruding section of the encoder wheel and rotationally connected with a shaft of the encoder, a groove is formed in the periphery of the straight section of the encoder wheel, a steel wire rope is wound around the groove, steel wire rope adjusters are arranged at the two ends of the steel wire rope respectively, one steel wire rope adjuster is connected with the movable stretching head, and the other steel wire rope adjuster is connected with the fixed stretching head. The utility model has the advantages of simple processing, low cost, long service life and high operation efficiency. And under the condition that the tension straightening machine vibrates slightly or two stretching heads move slightly in the working process, data transmission is not interrupted, and loss of elongation data of a product in the stretching process is not affected.
