The invention relates to a patch pocket machine folding feeding mechanism and belongs to the field of sewing mechanical equipment. The patch pocket machine folding feeding mechanism comprises a working platform, a horizontal beam, a lower die plate and an upper die pocket folding device. The upper die pocket folding device is fixed at one end of the horizontal beam. A motor is fixed on the horizontal beam. A guiding column is arranged vertically. One end of the guiding column is connected with the output end of a fixing motor. The other end of the guiding column is hinged to an upper die plate fixing frame. An upper die plate is fixed in the middle of the upper die plate fixing frame. The face, opposite to the working platform, of the upper die plate is the front face. An electromagnet is arranged on the back face of the upper die plate. Pocket bending inserting plates are arranged on the three side faces of the upper die plate fixing frame. The lower die plate is arranged under an upper die piece and is fixed on one guiding track of the horizontal beam. An electromagnet is arranged at the center of a projection zone of the working platform of the lower die plate. According to the patch pocket machine folding feeding mechanism, accurate patch pocket operation can be achieved, and deforming and dislocation of pockets can be avoided.
