The directional terms such as left, center, right, top, and bottom in the embodiments of the present invention are only relative concepts or referenced to the normal use state of the product, and should not be considered restrictive.

[0036] An automated method for forming screw-shaped wontons, such as... Figure 1 As shown, it includes the following steps:

[0037] Step 1: Combining Figure 3 As shown, at the wrapper placement station, wonton wrappers 22 are placed flat on the workbench and made to fit against the workbench; wherein, the workbench can be the top surface of the wrapper receiving plate 3, and a clearance hole 31 is provided on the wrapper receiving plate 3. A forming cup 1 is provided at the clearance hole 31. The forming cup 1 is raised and lowered relative to the wrapper receiving plate 3 and is positioned in the clearance hole 31. The upper part of the forming cup 1 is the forming part. The forming part is located below the top surface of the wrapper receiving plate 3. After the wonton wrapper 22 is placed on the wrapper receiving plate 3, the forming part can pass through the clearance hole 31 and be located above the wrapper receiving plate 3.

[0038] Step 2: Combining Figure 4 As shown, at the filling station, the wonton wrapper 22 is pressed downward into the filling groove 12, and the wonton wrapper 22 is made into a U-shaped structure with the opening facing upward under the limiting action of the left and right side walls of the filling groove 12; the U-shaped structure is that the left and right sides of the wonton wrapper 22 are in a vertical state, and the bottom of these two sides are connected by the horizontal state of the wrapper.

[0039] The filling groove 12 can be located inside the molding section, combined with Figure 2 As shown, the forming part includes a base plate 11 and two limiting plates 13 arranged side by side on the base plate 11. Both limiting plates 13 are vertically arranged and form a strip-shaped filling groove 12 between the base plate 11 and the limiting plates 13. The middle part of the filling groove 12 is the filling area. A clearance opening 14 is provided in the middle of the upper edge of both limiting plates 13. The clearance opening 14 can be a through hole or a notch. The clearance opening 14 corresponds to the filling area. It is best that the clearance openings 14 on the two limiting plates 13 correspond to each other to facilitate the folding of the corners of the wonton skin 22.

[0040] Step 3: filling in the center area of the U-shaped structure of the wrapper, and forming the dumpling ball 21; wherein the height of the end of the limiting plate 13 is lower than the middle part, and the middle part of the top surface of the limiting plate 13 is connected to the end of the top surface through a slope, which facilitates the U-shaped structure of the wrapper 22 after entering the filling slot 12 and limiting the wrapper 22, and also helps to reduce the overall weight of the forming cup;

[0041] Step 4: combining Figure 5 and Figure 6 As shown in the figure, at the folding corner station, two push plates 4 are inserted into the filling slot 12 from the left and right sides of the middle part of the filling slot 12, and the two push plates 4 are stacked on top of each other in the filling slot 12, leaving a holding gap between the two push plates 4 for holding two layers of wrappers, the height of the holding gap is 3mm-10mm, and the thickness of the two push plates 4 is preferably within 1.5mm-5mm, so as to adapt to wrappers of different thicknesses, and then the wrappers above the two sides of the dumpling ball 21 are overlapped and folded in the holding gap between the two push plates 4;

[0042] The lower push plate 4 approaches its end of travel first, and the upper push plate 4 approaches its end of travel later, so that the lower push plate 4 bends and positions the root of the folded part 23 first, and then the upper push plate folds and shapes the folded part 23; in order to achieve the above-mentioned action of the push plate 4, the lower push plate 4 is closer to the center line of the filling slot 12 than the other push plate 4 at the beginning of the movement, and after the two push plates 4 start moving synchronously, the lower push plate 4 moves first and approaches its end of travel first, i.e. approaches the root of the folded part 23 first, and then the other push plate 4 approaches its end of travel;

[0043] Step 5: the push plate 4 exits the filling slot 12, and the overlapped and folded wrappers form the folded part 23; the wrapper below the folded part 23 half-wraps the dumpling ball 21 to form a half-formed dumpling belly 201; under the action of gravity, the folded part 23 naturally droops onto the half-formed dumpling belly 201; the width of the folded part 23 is preferably less than or equal to the width of the filling slot 12, so that the folded part 23 can be completely placed in the filling slot 12 in a horizontal state, which requires that the end of travel of the two push plates 4 is close to the side wall of the filling slot 12 on the corresponding side, and the end of the push plate 4 and the side wall of the filling slot 12 do not clamp the wrapper 22;

[0044] Step 6: combining Figure 7As shown, at the gathering station, two pinch claws 51 extend into the filling slot 12 from above and press the dumpling wrapper 22 on the front and back sides of the semi-formed dumpling belly 201, and the dumpling wrapper 22 on the front and back sides of the semi-formed dumpling belly 201 is squeezed and pinched to form the completed pinched formed dumpling belly 202. At this time, the pinch claws 51 are preferably close to or in contact with the formed dumpling belly 202.

[0045] Step 7: The two pinch claws 51 are moved towards each other along the length direction of the filling slot 12, and the dumpling wrapper 22 below the pinch claws 51 is moved synchronously.

[0046] Step 8: The two pinch claws 51 are moved away from each other along the length direction of the filling slot 12, and the dumpling wrapper 22 below the pinch claws 51 is moved synchronously. Figure 8 Figure 9 As shown, the formed dumpling belly 202 is squeezed by the two pinch claws 51, and the wrapper on the formed dumpling belly 202 is wrinkled under the limiting action of the left and right side walls of the filling slot 12.

[0047] In order to facilitate the formation of the wrinkles on the formed dumpling belly 202, the top of the formed dumpling belly 202 is pressed or limited during the squeezing of the formed dumpling belly 202 by the two pinch claws 51, thereby limiting the height of the formed dumpling belly 202, and facilitating the formation of more wrinkles in the transverse direction. Specifically, a pressing rod 52 can be arranged between the two pinch claws 51, one end of the pressing rod 52 is fixedly connected with one of the pinch claws 51, the other end of the pressing rod 52 penetrates through the other pinch claw 51 and is in sliding cooperation with the other pinch claw 51, and the lower part of the pressing rod 52 close to the pinch claw 51 is used to press or limit the top of the formed dumpling belly 202. The bottom of the pressing rod 52 for contacting the formed dumpling belly 202 is a flat surface or an arc surface.

[0048] Step 9: The formed screw-shaped dumpling 203 is completed, and the actual shape of the screw-shaped dumpling 203 is as shown in Figure 10 Figure 11 In addition, the wrapper connecting plate 3 can be arranged on one side of a rotating disc (not shown in the figure), and the wrapper connecting plate 3 is moved between the various stations by the rotation of the rotating disc. The formed cup 1 and the wrapper connecting plate 3 are synchronously moved. In addition, in order to facilitate the removal of the formed screw-shaped dumpling 203 from the filling slot 12, after the two pinch claws 51 complete the squeezing action on the formed dumpling belly 202, the formed screw-shaped dumpling 203 is completed, and the two pinch claws 51 have a clamping action on the formed screw-shaped dumpling 203. Then, the distance between the two pinch claws 51 is kept unchanged, and the formed screw-shaped dumpling 203 is taken out of the filling slot 12 and transferred to the next packaging station.
