At least one demolding rotary disc includes a disc body formed with a shaft hole by which a retention key is provided. The demolding rotary disc is fit to an end of a molding cutter of one of the mold rollers by means of the shaft hole for synchronous rotation therewith. At least one demolding pawl is raised from one side of the disc body that is adjacent to the molding cutter. A tubular dough skin filled with stuffing is supplied between the two molding cutters to be pressed and cut and then sealed to form a dumpling. Demolding of the dumpling is achieved by having the demolding pawl that is provided on the demolding rotary disc contact and push one side of the dumpling. ## Claims ### Claim 1 A stuffing and molding mechanism of a dough food product processing machine, at least comprising: a stationary structure, which comprises two side boards arranged opposite to each other, the two side boards being formed with two shaft holes and two elongate shaft holes opposite to each other; a first mold roller, which comprises a transmission shaft penetrating through a molding cutter, the transmission shaft having an end section to which a toothed wheel assembly is mounted, the first mold roller being arranged to have the transmission shaft extending through and supported on the shaft holes of the two side boards so as to support the molding cutter between the two side boards; a second mold roller, which comprises a transmission shaft penetrating through a molding cutter, the transmission shaft having an end section to which a toothed wheel assembly is mounted, the second mold roller being arranged to have the transmission shaft extending through and supported on the elongate shaft holes of the two side boards so as to support the molding cutter between the two side boards, wherein the first mold roller and the second mold roller are arranged such that the molding cutters are in mating engagement with each other and the toothed wheel assemblies are coupled to a power mechanism to be rotatable synchronously; and at least one demolding rotary disc, which comprises a disc body that is formed with a shaft hole in a central portion thereof so that the at least one demolding rotary disc is fit, through the shaft hole, to one end of the molding cutter of one of the mold rollers, the disc body having a side surface that is adjacent to the molding cutter and is formed with at least one demolding protrusion raised therefrom, wherein a tubular dough skin that is filled with a stuffing material, upon entry into a space between the two molding cutters, is subjected to pressing and cutting and sealing to form a dumpling, which is demolded by having a side of the dumpling contacted and pulled out by the at least one demolding protrusion that is provided on the at least one demolding rotary disc. ### Claim 2 (depends on 1) The stuffing and molding mechanism according to claim 1, wherein the at least one demolding protrusion of the disc body comprise a number of the demolding protrusions, the number being greater than one. ### Claim 3 (depends on 1) The stuffing and molding mechanism according to claim 1, wherein the first mold roller and the second mold roller are paired with each other in a vertical direction as being positioned at upper and lower sides respectively. ### Claim 4 (depends on 1) The stuffing and molding mechanism according to claim 1, wherein the at least one demolding rotary disc comprises two demolding rotary discs that are respectively fit to two ends of the molding cutter of the one of the mold rollers. ### Claim 5 (depends on 1) The stuffing and molding mechanism according to claim 1, wherein the at least one demolding rotary disc comprises a retention key that is mounted by one of a spring button, screwing, adhesive bonding, riveting, fitting, and welding or by means of a transmission including a key or a pin, to have the at least one demolding rotary disc and the molding cutter of the one of the mold rollers rotatable simultaneously. ### Claim 6 (depends on 1) The stuffing and molding mechanism according to claim 1, wherein the at least one demolding protrusion of the at least one demolding rotary disc has a configuration that is selected as one of a peg with a dome-shaped top, an elevated sphere, a raised hemisphere, a curved peg, and a raised wedge. ### Claim 7 (depends on 1) The stuffing and molding mechanism according to claim 1, wherein the at least one demolding rotary disc has a surface area that covers a pressing and cutting site of the two molding cutters. ### Claim 8 (depends on 1) The stuffing and molding mechanism according to claim 1, wherein the at least one demolding protrusion and the disc body are integrally formed together. ### Claim 9 (depends on 1) The stuffing and molding mechanism according to claim 1, wherein the first mold roller is provided, on a top side thereof, with a powder spraying device. ### Claim 10 (depends on 1) The stuffing and molding mechanism according to claim 1, wherein the stationary structure is provided with a lower doctor blade under the first mold roller and the second mold roller.
