The invention relates to the field of processing equipment, in particular to a folding paper I-shaped handle processing machine. The folding paper I-shaped handle processing machine comprises a mounting plate, a cutting knife mechanism, a pressure plate forming mechanism, a flanging glue pressing mechanism and a finished product separating mechanism. The pressure plate forming mechanism, the flanging glue pressing mechanism and the finished product separating mechanism gradually complete the folding of an I-shaped handle after paper strips are cut off, compared with the manual folding, the speed is higher, the product quality is stable, the working hours are saved, and the production cost is reduced.
