Coiled material discharging device for building waterproof engineering

The coiled material discharging device for the building waterproof engineering comprises a fixed bottom plate, universal trundles are installed on the four sides of the bottom of the fixed bottom plate, supporting stand columns are connected to the two sides of the top of the fixed bottom plate, and the supporting stand columns are of a telescopic column structure. A first fixing plate and a second fixing plate are connected to the tops of the supporting stand columns on the two sides correspondingly, a fixing butt strap is installed outside the bottom end of the servo motor, the first fixing plate is connected to the outside of the side edge of the fixing butt strap, a connecting through hole is formed in the second fixing plate, and a driven rotating shaft is connected to the interior of the connecting through hole in an embedded mode. The outer end of the driven rotating shaft is connected with a pull ring, and the axis of the driven rotating shaft coincides with the axis of the driving rotating shaft. Acc
