A feeding structure for folding umbrella fabric includes a base and a suction cup. The suction cup includes a rotating end and an adsorption end. The rotating end is connected to a servo motor. Several adsorption ports are formed on the lower annular surface of the adsorption end. These ports are connected to an external vacuum extraction device through connecting holes inside the suction cup. The base is equipped with a feeding rod and a folding umbrella fabric mechanism. The feeding rod is vertically adjustable on the base. The folding umbrella fabric mechanism includes an embossing surface. The lower annular surface of the adsorption end is higher than the embossing surface. A negative pressure sensor connected to the connecting holes is provided on the base. The servo motor controls the rotation of the suction cup. When the suction cup rotates above the feeding rod, the feeding rod lifts the umbrella fabric to below the adsorption end. The suction cup then adsorbs the umbrella fabric through the adsorption ports. The servo motor rotates the suction cup, causing the adsorption end to rotate onto the embossing surface of the folding umbrella fabric mechanism. This invention provides uniform adsorption of the umbrella fabric, ensuring that the umbrella fabric does not pull up lower layers of umbrella fabric during the adsorption process.
