Description

Technical Field

[0001] This utility model belongs to the field of food processing equipment manufacturing technology, and in particular relates to dumpling forming molds. Background Technology

[0002] With the increasing application of automated production in the frozen food manufacturing industry, the market demand for automated production equipment for frozen dumplings is also increasing. There are already many food forming devices that can produce dumplings. However, when these devices compress dumplings, in order to achieve a handmade effect, they need to form a pleated structure on the pressing edge. However, the traditional pleated structure is the bending and overlapping of two layers of dough. In addition to the original two layers of dough in the pressing part, there are a total of four layers of dough. When these four layers of dough overlap, the joints of the dough are not easy to cook through, which ultimately affects the taste of the dumplings.

[0003] Existing technology, such as Chinese invention patent CN107047680A entitled "Mold for Forming Filled Foods," discloses the following: This invention belongs to the field of food processing technology, and particularly relates to a mold for forming filled foods by processing the outer surface of the dough into wrinkles. It includes a receiving plate and a mold cup. The receiving plate has a forming hole, and the mold cup passes through the forming hole. The upper inner sidewall of the mold cup has a stepped structure in the shape of a semi-circular arc or a full arc. Below the step on the inner sidewall of the mold cup, multiple strip-shaped protrusions are evenly distributed. A strip-shaped groove is formed between two adjacent strip-shaped protrusions. The strip-shaped groove is adapted to multiple protrusions on the dough-pulling head and is evenly distributed on the inner sidewall of the mold cup. The strip-shaped groove and the protrusions compress the dough in a parallel direction. In actual use, the aforementioned patent creates multiple folds and patterns on the dough to achieve a handmade effect. However, some folds may extend to the sealing area of ​​the dumpling, resulting in multiple four-layer dough folds at the sealing area. This still cannot prevent the dumpling skin at the multi-layer dough folds from being difficult to cook. Summary of the Invention

[0004] To overcome the aforementioned problems of existing technologies, a dumpling forming mold is proposed that can create imitation handmade wrinkles without forming four layers of dough at the wrinkles.

[0005] To achieve the above-mentioned technical effects, the technical solution of this application is as follows:

[0006] A dumpling forming mold includes a support frame and a forming head. A receiving plate is installed on the support frame, and a forming through hole is provided on the receiving plate. A mold cup is provided in the forming through hole. The mold cup is characterized by having a forming groove with an overall oblique cross shape on its outer edge, and a forming protrusion with an overall oblique cross shape on the forming head.

[0007] The mold cup has four forming grooves. The left and right sides of the mold cup have left and right grooves, respectively, and the front and rear sides of the mold cup have front and rear grooves, respectively. The front and rear grooves are located on both sides of the horizontal center line of the mold cup and are symmetrically distributed with respect to the horizontal center of the mold cup. The forming head has four forming protrusions, namely the left protrusion, the right protrusion, the front protrusion, and the rear protrusion, which correspond to the positions of the left, right, front, and rear grooves, respectively.

[0008] Furthermore, the formed through hole includes a central formed hole, with a left through hole and a right through hole respectively connected to the left and right sides of the central formed hole, and a front through hole and a rear through hole respectively connected to the front and rear of the central formed hole.

[0009] The left convex strip moves up and down through the left through hole, the right convex strip moves up and down through the right through hole, the front convex strip moves up and down through the front through hole, and the rear convex strip moves up and down through the rear through hole.

[0010] Furthermore, the horizontal centers of the left and right grooves are connected to each other to form a horizontal line, and the centers of the front and rear grooves at the same horizontal height are connected to form a diagonal line. The horizontal and diagonal lines intersect obliquely in the mold cup, thus forming an intersecting oblique cross.

[0011] Furthermore, the skin-connecting plate is provided with a skin-connecting groove, the skin-connecting groove is a vertically arranged ellipse, and the central forming hole of the forming through hole is a horizontally arranged ellipse.

[0012] Furthermore, the left through hole passes through the splice groove and extends beyond the left side of the splice groove, and the right through hole passes through the splice groove and extends beyond the right side of the splice groove.

[0013] Furthermore, the bottom of the forming head is generally conical, and the bottom surface of each forming protrusion is an inclined surface that slopes towards the middle of the forming head. The middle of the forming head is a hollow structure, and a filling outlet is provided in the center of the bottom of the forming head. A filling inlet pipe is connected to the top of the forming head.

[0014] Furthermore, the left and right convex strips have the same thickness, the front and rear convex strips have the same thickness, and the front convex strip has a greater thickness than the left convex strip.

[0015] Furthermore, the outer edges of the front and rear sides of the mold cup both bulge upwards in an arc shape.

[0016] Furthermore, the left and right grooves on the mold cup are fan-shaped grooves with a central angle of 35-45 degrees and an arc-shaped bottom; the front and rear grooves are fan-shaped grooves with a central angle of 32-42 degrees and an arc-shaped bottom.

[0017] Furthermore, the mold cup is provided with a lifting mold core, the bottom of which is connected to a connecting rod, the connecting rod is connected to a crossbar, a first guide rod is fixed on the crossbar, the first guide rod passes through the crossbar, a first guide wheel is provided below the first guide rod, a spring is sleeved on the first guide rod, and the upper end of the spring is connected to a support frame.

[0018] Furthermore, the two sides of the connecting plate are rotatably connected to one end of the fork, the middle of the fork is rotatably connected to the connecting block, the connecting block is fixed on the support frame, and a second guide rod is provided at the other end of the fork, with a second guide wheel at the end of the guide rod.

[0019] Furthermore, the front groove of the mold cup is located slightly to the left of the center of the mold cup, and the rear groove is located slightly to the right of the center of the mold cup.

[0020] Furthermore, the front groove of the mold cup is located slightly to the right of the center of the mold cup, and the rear groove is located slightly to the left of the center of the mold cup.

[0021] The advantages of this application are:

[0022] 1. This application sets obliquely intersecting grooves on the mold cup and sets corresponding obliquely intersecting convex strips on the forming head. Through the cooperation of the grooves and convex strips, a three-layer folded structure is formed at the grooves and convex strips on the front and back sides of the dough. This ensures that after the dough is pressed and sealed, it can not only ensure the firmness of the pressing, but also ensure that the pressed part can be easily cooked and there will be no undercooked dough.

[0023] 2. The receiving plate of this application is provided with a through hole for the protrusion of the forming head to pass through, which makes it easier for the forming head to push the dough into the mold cup downward.

[0024] 3. The elliptical shape formed by the receiving groove in the receiving plate of this application and the elliptical shape of the central forming hole are horizontally and vertically distributed. This makes it easier to transform the dough from its initial flat state to its forming state, and makes it easier to shape the dough into a dumpling shape.

[0025] 4. The thicker front and rear convex strips in this application are designed to form a larger fold inward. The larger fold makes it easier to separate the inner and outer skin of the fold, thus achieving a three-layer skin pressing structure. The thinner left and right convex strips are designed to make the gaps narrower when the front and back sides of the skin are folded, which facilitates subsequent pressing.

[0026] 5. The front and rear outer edges of the mold cup in this application are both raised upwards in an arc shape, which can avoid interference between the mold cup and the pressing module, so that the pressing part of the final formed dumpling also has an upwardly raised arc shape.

[0044] Example 1

[0045] like Figure 1 As shown, a dumpling forming mold includes a support frame 1 and a forming head 2. A receiving plate 3 is installed on the support frame 1. A forming through hole is provided on the receiving plate 3. A mold cup 4 is provided in the forming through hole. A forming groove in an oblique cross shape is provided on the outer edge of the mold cup 4. A forming protrusion in an oblique cross shape is provided on the forming head 2.

[0046] like Figures 2-6 As shown, the mold cup 4 is provided with four forming grooves. The left side of the mold cup 4 is provided with a left groove 5 and a right groove 6 respectively. The front side of the mold cup 4 is provided with a front groove 7 and a rear groove 8 respectively. The front groove 7 and the rear groove 8 are located on both sides of the horizontal center line 9 of the mold cup, and the front groove 7 and the rear groove 8 are symmetrically distributed with respect to the horizontal center 10 of the mold cup. That is, the front groove 7 is located to the left or right of the center of the mold cup 4, and the rear groove 8 is located to the right or left of the center of the mold cup 4. The forming head 2 is provided with four forming protrusions, namely the left protrusion 11, the right protrusion 12, the front protrusion 13 and the rear protrusion 14. The four forming protrusions correspond to the positions of the left groove 5, the right groove 6, the front groove 7 and the rear groove 8 respectively.

[0047] The left groove 5 and the right groove 6 together form the horizontal line of the diagonal cross, and the front groove 7 and the rear groove 8 together form the diagonal line of the diagonal cross. The horizontal and diagonal lines intersect each other diagonally. The left convex strip 11 and the right convex strip 12 together form the horizontal line of the diagonal cross, and the front convex strip 13 and the rear convex strip 14 together form the diagonal line of the diagonal cross. The horizontal and diagonal lines intersect each other diagonally.

[0048] Example 2

[0049] like Figure 1 As shown, a dumpling forming mold includes a support frame 1 and a forming head 2. A receiving plate 3 is installed on the support frame 1. A forming through hole is provided on the receiving plate 3. A mold cup 4 is provided in the forming through hole. A forming groove in an oblique cross shape is provided on the outer edge of the mold cup 4. A forming protrusion in an oblique cross shape is provided on the forming head 2.

[0050] like Figures 2-6 As shown, the mold cup 4 is provided with four forming grooves. The left side of the mold cup 4 is provided with a left groove 5 and a right groove 6 respectively. The front side of the mold cup 4 is provided with a front groove 7 and a rear groove 8 respectively. The front groove 7 and the rear groove 8 are located on both sides of the horizontal center line 9 of the mold cup, and the front groove 7 and the rear groove 8 are symmetrically distributed with respect to the horizontal center 10 of the mold cup. That is, the front groove 7 is located to the left or right of the center of the mold cup 4, and the rear groove 8 is located to the right or left of the center of the mold cup 4. The forming head 2 is provided with four forming protrusions, namely the left protrusion 11, the right protrusion 12, the front protrusion 13 and the rear protrusion 14. The four forming protrusions correspond to the positions of the left groove 5, the right groove 6, the front groove 7 and the rear groove 8 respectively.

[0051] The left groove 5 and the right groove 6 together form the horizontal line of the diagonal cross, and the front groove 7 and the rear groove 8 together form the diagonal line of the diagonal cross. The horizontal and diagonal lines intersect each other diagonally. The left convex strip 11 and the right convex strip 12 together form the horizontal line of the diagonal cross, and the front convex strip 13 and the rear convex strip 14 together form the diagonal line of the diagonal cross. The horizontal and diagonal lines intersect each other diagonally.

[0052] The forming through hole includes a central forming hole 15, with a left through hole 16 and a right through hole 17 connected to the left and right sides of the central forming hole 15, respectively. A front through hole 18 and a rear through hole 19 are connected to the front and rear of the central forming hole 15, respectively.

[0053] The left convex strip 11 passes through the left through hole 16 by moving up and down, the right convex strip 12 passes through the right through hole 17 by moving up and down, the front convex strip 13 passes through the front through hole 18 by moving up and down, and the rear convex strip 14 passes through the rear through hole 19 by moving up and down.

[0054] Because the mold cup 4 is provided with a left groove 5, a right groove 6, a front groove 7 and a rear groove 8, and the front groove 7 and the rear groove 8 are eccentrically positioned relative to the center of the mold cup 4 and are symmetrically positioned on both sides of the center line of the mold cup 4, and the forming head 2 is provided with four forming protrusions corresponding to the four through holes, when the forming head 2 moves downward and contacts the skin above the mold cup 4, it continues to move downward and pushes the middle part of the skin into the mold cup 4. At this time, under the action of contact between the skin and the mold cup 4 and the forming head 2, inward shrinkage wrinkles will be generated at the positions of the front groove 7 and the rear groove 8. In the subsequent pressing process, the wrinkled skin and the front and rear sides of the skin can form a three-layer skin folding structure.

[0055] The left through hole 16, right through hole 17, front through hole 18 and rear through hole 19 provided in the forming through hole are used to facilitate the passage of the four protrusions on the forming head 2.

[0056] The left groove 5 and right groove 6 are horizontally connected at their centers, forming a horizontal line. The front groove 7 and rear groove 8 are horizontally connected at their centers, forming a diagonal line. The horizontal and diagonal lines intersect obliquely in the mold cup 4, forming an intersecting diagonal cross. Since the positions of the four protrusions on the forming head 2 correspond to the left groove 5, right groove 6, front groove 7, and rear groove 8, the left protrusion 11 and right protrusion 12 can be considered as connected as a horizontal line, and the front protrusion 13 and rear protrusion 14 can be considered as connected as a diagonal line. At this time, the horizontal and diagonal lines intersect obliquely in the middle of the forming head 2. The diagonally intersecting distribution ensures that when the dough comes into contact with and is squeezed by the forming head 2 and the mold cup 4, a three-layer folded part is formed on the front and back sides of the dough. This three-layer structure ensures that the dough adheres more tightly when it is pressed together later, making it less likely for the dough to burst open. Furthermore, the three layers of dough folded together are easier to cook than the four-layer dough structure, and there will be no raw skin during the cooking process.

[0057] like Figure 7 As shown, the receiving plate 3 is provided with a receiving groove 20, which is a vertically arranged ellipse. The central forming hole 15 of the forming through hole is a horizontally arranged ellipse. Here, "vertical arrangement" and "horizontal arrangement" refer to the fact that, when viewed from above, relative to the plane formed by the surface of the receiving plate 3, both ellipses are parallel to the upper surface of the receiving plate 3, and the vertically arranged ellipse and the horizontally arranged ellipse are perpendicular to each other from a top-view perspective. The ellipse of the receiving groove 20 is to receive the vertically arranged elliptical surface layer, while the ellipse of the central forming hole 15 is to accommodate the elliptical mold cup 4 through which it passes.

[0058] The left through hole 16 passes through the receiving groove 20 and extends beyond the left side of the receiving groove 20, while the right through hole 17 passes through the receiving groove 20 and extends beyond the right side of the receiving groove 20. Since the dumpling wrapper is located in the receiving groove 20, when the forming head 2 moves downward, in order to tighten the left and right sides of the dumpling wrapper inward, the forming protrusions on the left and right sides of the forming head 2 should contact the dumpling wrapper as much as possible. Furthermore, the forming effect is better when the forming protrusions extend beyond the dumpling wrapper.

[0059] like Figure 4 As shown, the bottom of the forming head 2 is conical, and the middle part of the forming head 2 is hollow. A filling outlet is provided in the center of the bottom of the forming head 2, and a filling inlet pipe is connected to the top of the forming head 2. The filling inlet pipe transports the filling to the hollow structure in the forming head 2, and injects the filling onto the dumpling wrapper through the filling outlet in the center of the bottom of the forming head 2.

[0060] The left convex strip 11 and the right convex strip 12 have the same thickness, the front convex strip 13 and the rear convex strip 14 have the same thickness, and the thickness of the front convex strip 13 is greater than the thickness of the left convex strip 11.

[0061] The forming protrusions and grooves on the left and right sides of the dough are folded from a flat state to a vertical state to facilitate subsequent pressing and shaping.

[0062] The front and rear outer edges of the mold cup 4 are both convex upwards in an arc shape. The purpose of the arc shape is to avoid interference with the subsequent pressing module. The pressing part of the existing pressing module is an upwardly convex arc mechanism. So when the dough is folded up from the mold cup 4 and exposed, the exposed dough is also an upwardly convex arc structure. Then, it is pressed together by the pressing part with the same shape to finally form a dumpling.

[0063] The left groove 5 and right groove 6 on the mold cup 4 are fan-shaped grooves with a central angle of 35-45 degrees, preferably 37 degrees or 42 degrees, and the bottom of the fan-shaped groove is arc-shaped; the front groove 7 and rear groove 8 are fan-shaped grooves with a central angle of 32-42 degrees, preferably 35 degrees or 40 degrees, and the bottom of the fan-shaped groove is arc-shaped.

[0064] A lifting mold core 21 is provided in the mold cup 4. The bottom of the lifting mold core 21 is connected to the connecting rod 22, which is connected to the crossbar 23. A first guide rod 24 is fixed on the crossbar 23 and passes through the crossbar 23. A first guide wheel 26 is provided below the first guide rod 24, and a spring 25 is sleeved on the first guide rod 24. The upper end of the spring 25 is connected to the support frame 1. The first guide wheel 26 drives the first guide rod 24 to move, and the first guide rod 24 drives the crossbar 23 and the connecting rod 22 to raise or lower the lifting mold core 21.

[0065] The two sides of the leather plate are rotatably connected to one end of the fork 27. The middle of the fork 27 is rotatably connected to the connecting block 28, which is fixed to the support frame 1. A second guide rod 29 is provided at the other end of the fork 27, and a second guide wheel 30 is provided at the end of the second guide rod 29. The second guide wheel 30 drives the guide rod to move, and the second guide rod 29 drives the fork 27 to move, causing the leather plate 3 to rise or fall.

[0066] The front groove 7 of the mold cup 4 is located slightly to the left of the center of the mold cup 4, and the rear groove 8 is located slightly to the right of the center of the mold cup 4.

[0067] Alternatively, the front groove 7 of the mold cup 4 can be located slightly to the right of the center of the mold cup 4, and the rear groove 8 can be located slightly to the left of the center of the mold cup 4.

[0068] The working principle of this application is as follows:

[0069] Step 1: Place the dough on the forming through hole of the receiving plate 3;

[0070] Step 2: The forming head 2 moves downwards, inserting the dough into the mold cup 4 located below the forming through hole. At this time, the outer edges of the dough contact the inner wall of the mold cup 4, and the bottom of the dough contacts the lifting mold core 21. The dough is concave in shape. The forming head 2 is provided with forming protrusions that are generally shaped like an oblique cross. The forming protrusions correspond to the forming grooves that are generally shaped like an oblique cross on the outer edge of the mold cup 4. They work together to gather the part of the dough located between the forming protrusions and the forming grooves to form wrinkles. The dough shape is as follows: Figure 8 As shown;

[0071] Step 3: While the shaping head 2 is inserting into the dough, the filling is injected into the dough.

[0072] Step 4: The forming head 2 moves upward, and the pressing device seals the outer edge of the dough that has been formed into a concave shape. The folds on the front and back sides of the dough are pressed together to form a three-layer dough structure, and the dumpling is formed.

[0073] The cooperation of the forming groove and the forming protrusion on the front and back sides of the dough allows the dough to form a fold that bulges towards the center of the dough on both the front and back sides. The two folds are staggered. Each fold includes an outer fold and an inner fold. As the forming head 2 moves downward, the inner folds of the two folds are gradually pressed down towards the center of the dough by the top of the forming head 2, while the outer folds remain relatively vertical. When the pressing device presses the dough in the above state, a three-layer pressing structure of front side dough, outer fold, and back side dough is formed at the folds on the front and back sides of the dough.

[0074] Step 5: The receiving plate 3 descends, exposing the formed dumplings. The unloading device then transfers the formed dumplings to the subsequent workstation.
