Welding wire guide plate mechanism

The utility model relates to a welding wire guide plate mechanism, which is characterized in that a wire feeding hose with a joint is fastened with a fixing block, the fixing block is fixed on a plate body, a guide wheel shaft is connected with the plate body, a thin gasket is connected to the guide wheel shaft through a combined nut, a movable wire guide wheel shaft is connected with the plate body, a fixed wire guide wheel is connected to the movable wire guide wheel shaft through an elastic retaining ring and a combined nut, a fixed wire guide wheel shaft is connected to the plate body via thread, a movable wire guide wheel is connected with the fixed wire guide wheel shaft through an elastic retaining ring and a combined nut, and the plate body is connected with a wire feeding machine head through an internal hexagonal screw. The welding wire guide plate mechanism is simple, compact and reasonable in structure, welding wires directly enter a guide roller wheel through the wire feeding hose which is convenient and fast in installation, and the movable wire guide wheel coarsely straightens welding wires. Wire feeding resistance of the welding wires before entering the wire feeding machine head can be reduced by the large arc-shaped transition greatly, and straightening effect of the wire feeding machine head and welding stability can be increased by aid of a coarse straightening function, and then the welding wire guide plate mechanism is particularly adaptable to far-distance welding of thick wires.
