Common cup-associated products are mainly small cups of yogurt. The cup body of the yogurt of the cup-combining product is generally in an inverted cone-shaped structure or a cylindrical structure, and the cup body is in a structure with a wide upper part and a narrow lower part. The production equipment of the united cup product can process the sheet into the cup body, and then the material is filled into the cup body and is output outwards after being sealed. The sheet is heated and then the softened sheet is conveyed to a cup body forming device. The cup body forming device is used for producing a cup body in a thermoplastic extrusion mode and comprises a female die and a male die, wherein a forming cavity matched with the outline of the cup body is arranged in the female die, and the forming cavity is small at the bottom and large at the top and is matched with a structure with the wide top and the narrow bottom of the cup body. The male die is provided with a stretching column and an air supply structure. When the heated and softened sheet is positioned in the cup body forming device, the female die is positioned below the sheet, and the male die is positioned above the sheet; after the female die is contacted with the sheet, a stretching column on the male die is firstly contacted with the sheet and extrudes the sheet into a forming cavity of the female die; after the sheet is extruded by the stretching column, the sheet is stretched in the forming cavity; after other parts of the male die are contacted with the sheet, introducing compressed air into the sheet which is stretched and deformed by an air supply structure on the male die, and blowing and expanding the sheet until the profile of the sheet is consistent with the profile of a forming cavity of the die; after demolding, the cup body is formed on the originally flat sheet.

The structural characteristics of the prior art matrix determine the limitation of the cup body structure to cylindrical and inverted conical shapes, and any other cup body structure that tends to be or is significantly narrow at the top and wide at the bottom is an obstacle to the demolding process, even if the cup body obtains the desired shape in the mold and eventually cannot be produced properly because it cannot be separated from the mold.

With the increasing market favor of the container with the tank structure, the objective requirement of the combined cup body of the yogurt product on using the tank structure is more urgent. The cup body forming device of the cup product production equipment in the prior art can only produce cylindrical and inverted conical containers, and the market demand cannot be met at all.
