[0044] Add filling, kneaded dough, and dry flour to filling hopper 23, dough hopper 35, and dry flour hopper 6 respectively, and start the system by pressing switch button 7.

[0045] Clutch 25 is engaged, and the power system drives the filling pump 22 via clutch 25. The dumpling filling in the filling hopper 23 is stirred and squeezed by the filling shaft 24 and the filling auger 27 to the bottom and enter the filling pump 22. The filling pump 22 then supplies the filling to the filling tube 26. The power system drives the spiral mixing shaft 37 and the dough auger 31 to rotate via the gearbox 5. The spiral mixing shaft 37 stirs and squeezes the dough and conveys it to the bottom of the dough box 34. The dough auger 31 then sends it to the rear outlet of the dough sleeve 36. The dough enters the dough storage gap formed between the inner nozzle 32 and the outer nozzle 33, and is continuously conveyed by subsequent dough. During extrusion, the dough is extruded from the gap between the inner nozzle 32 and the outer nozzle 33 to form a dough tube. Since the filling tube 26 is located inside the hollow shaft tube of the dough auger 31, the dumpling filling delivered by the filling tube 26 is wrapped in the dough tube, forming a filled dough tube. The dry flour hopper 6 sprinkles dry flour onto the filled dough tube, and then the filled dough tube is sent to the forming gap between the upper forming mold 42 and the lower forming mold 43. As the upper forming mold 42 and the lower forming mold 43 rotate, the dumplings are pressed and cut into shape and fall onto the finished product guide inclined plate 44, and then guided to the finished product conveying equipment for conveying and collection.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
