The invention relates to an electron-pattern-sewing machine pillow material pressing mechanism and belongs to the field of sewing machines. The mechanism comprises a cylinder mounting seat and a universal connecting sleeve, a transverse positioning shaft and a longitudinal positioning shaft are arranged on the universal connecting sleeve, the left end and the right end of the transverse positioning shaft are connected with a left side plate and a right side plate respectively, the left side plate is connected with a pressing foot component, the right side plate is connected with a cylinder support, a cylinder mounting plate is connected above the cylinder support, a resetting cylinder is mounted on the cylinder mounting plate, and an upper cover is connected below the resetting cylinder. The electron-pattern-sewing machine pillow material pressing mechanism has the advantages that the pressing foot component moves along with a material, and a sewing material drives a pressing foot to move to ensure uniformity of movement tracks, so that pillowcase sewing efficiency can be improved effectively, production cost is lowered, and processing accuracy is improved.
