Description

Technical Field

[0001] The utility model relates to the field of steel wire processing, in particular to a wire-releasing device. Background Art

[0002] Steel wire is one of the four major types of steel: plate, tube, profile and wire. It is a reprocessed product made from hot-rolled wire rods by cold drawing. The main processes of steel wire production include raw material selection, removal of iron oxide scale, drying, coating treatment, heat treatment, wire drawing, plating treatment, etc. During the processing, a stable unwinding device is required to unwind the steel wire to facilitate the next step of processing.

[0003] After searching, the Chinese patent announcement number is CN220744885U, which discloses a cable pay-off device for power infrastructure construction. When installing the reel with the cable for power infrastructure, the reel is placed on the top of the base between the fixed bracket and the movable bracket, and the movable bracket is driven to move toward the reel by rotating the screw until the two sides of the reel are plugged into the corresponding rotating shafts. The multi-stage hydraulic cylinder is started to drive the reel to rise through the movable block until the cable in the reel contacts the pressure roller on the top, so as to achieve the effect of facilitating the installation and replacement of the reel, avoiding the problem of personal injury caused by manual lifting during the installation of the reel, or reducing the practicality of the pay-off device by equipping a lifting equipment.

[0004] However, since the steel wire has high elasticity, when you stop pulling the steel wire and stop paying out the wire, the steel wire may become loose or even spread out due to the disappearance of the paying out tension, making it inconvenient for the next paying out. Utility Model Content
