Description

Technical Field

[0001] This utility model belongs to the field of food processing technology, specifically relating to an automatic dumpling skin forming device. Background Technology

[0002] Dumplings, as a traditional food with special significance, are loved by many. They are made by wrapping fillings in dough. Traditional or homemade dumplings are usually made by hand. However, in noodle shops or canteens, relying solely on handmade production cannot meet consumer demand, resulting in low production efficiency. Furthermore, the thickness of the dough wrappers made by different people can vary, affecting the taste of the dumplings. Therefore, machines have emerged to automatically make dough wrappers. These machines repeatedly roll the dough with multiple sets of rollers to form dough wrappers of uniform thickness. This not only increases production efficiency but also ensures uniform dough thickness. However, existing dough wrapper making equipment usually has many internal parts, resulting in a large size that requires a lot of space. It is also extremely inconvenient for transportation, storage, and handling. Utility Model Content

The first pressing mechanism is located at the bottom and a feeding area is provided above the first pressing mechanism. The bottom of the feeding area is connected to the first pressing mechanism. After the dough to be processed is placed in the feeding area, it can be rolled and gradually thinned from bottom to top in a ring shape by the first pressing mechanism, the second pressing mechanism, the third pressing mechanism and the fourth pressing mechanism, and finally output as a long strip of dough with moderate thickness and uniformity.

[0005] Furthermore, the first pressing mechanism, the second pressing mechanism, the third pressing mechanism and the fourth pressing mechanism each include two mounting plates and two pressing rollers. The mounting plates are screwed to the frame and fixed. The two pressing rollers are installed between the two mounting plates and rotate in opposite directions.

The longitudinal conveyor belt is provided with a plurality of toothed racks.

[0010] Furthermore, a second conveyor belt is provided between the second pressing mechanism and the third pressing mechanism.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] like Figure 1 As shown, this utility model provides an automatic dumpling wrapper forming device, including a frame 1 and a first pressing mechanism 2, a second pressing mechanism 3, a third pressing mechanism 4, and a fourth pressing mechanism 5 arranged in a ring on the frame 1. This maximizes space utilization, making the layout of each pressing mechanism more compact and avoiding the need for large spaces due to horizontal or vertical arrangements. The first pressing mechanism 2 is located at the bottom, and a feeding area 11 is provided above it. The bottom of the feeding area 11 is connected to the first pressing mechanism 2, meaning the feeding area 11 is located at the center of the ring shape, thus fully utilizing space... The circular spatial layout allows for a more compact arrangement of structures and reduces space occupation. The feeding area 11 is trapezoidal in shape to expand the feeding port area, facilitating feeding. After the dough to be processed is placed in the feeding area 11, it can be directly pushed out from below by the first pressing mechanism 2, and then rolled upwards in a circular pattern through the first pressing mechanism 2, the second pressing mechanism 3, the third pressing mechanism 4, and the fourth pressing mechanism 5, gradually thinning until it is output as a long strip of dough with moderate and uniform thickness. The final output position is still higher than the first pressing mechanism 2, facilitating the conveying of the dough to the next processing position without further guidance, thus simplifying the structure. By setting up multiple pressing mechanisms, the dough can be rolled multiple times, gradually forming a dough sheet of moderate and uniform thickness. The texture is more chewy and closer to that of handmade dough compared to dough that has only been pressed once or twice.

[0029] Specifically, such as Figure 2 As shown, the first pressing mechanism 2, the second pressing mechanism 3, the third pressing mechanism 4, and the fourth pressing mechanism 5 have basically the same structure. They all include two mounting plates 21 and two counter-rotating pressing rollers 22 installed between the two mounting plates 21. One mounting plate 21 is fixedly connected to the frame 1, and the other mounting plate 21 is fixedly connected to the frame 1 through several fixed shafts. The two pressing rollers 22 are rotatably connected between the two mounting plates 21 through a rotating shaft. The pressing rollers 22 are provided with inclined grooves 221 arranged around the peripheral wall. The inclined grooves 221 guide air to be discharged in a specific direction when the dough is squeezed, reducing air bubbles in the dough and preventing voids or delamination in the finished product. At the same time, the inclined grooves 221 can disrupt the continuous contact between the dough and the roller surface, reducing the risk of sticking and allowing the dough to be conveyed with the rotation of the two pressing rollers 22. At the same time, anti-sticking powder (such as starch) can be dispersed through the grooves to improve the demolding effect.

[0030] It should be noted that the surface of the dough after being rolled by the inclined groove will have corresponding indentations, which helps to increase friction and improve conveying efficiency. However, since the dough is directly used for cutting, filling and sealing after being pressed by the fourth dough pressing mechanism 5, the two pressing rollers 22 of the fourth dough pressing mechanism 5 do not have the inclined grooves 221. The surfaces of the two pressing rollers 22 are smooth, so as to transform the dough with indentations into a dough with uniform thickness and a smooth surface, so that the final dumplings have a smooth outer surface and better taste. In addition, the uniform thickness can ensure that the cooking time is the same, avoiding inconsistent steaming and cooking times that affect the taste.

[0031] Preferably, such as Figure 4 As shown, in order to increase the space of the feeding area 11, the radius R1 of the two pressing rollers 22 of the first pressing mechanism 2 is greater than the radius R2 of the pressing rollers 22 of the second pressing mechanism 3, the third pressing mechanism 4 and the fourth pressing mechanism 5, so as to increase the contact area between the two pressing rollers 22 of the first pressing mechanism 2 and the dough, so that enough dough can be placed at one time, reducing the number of times the dough is fed and improving production efficiency.

[0032] Furthermore, such as Figure 5As shown, the pressing roller 22 is equipped with a scraper 23, which is screwed to the mounting plate 21. The scraper 23 is inclined in the opposite direction to the rotation direction of the pressing roller 22, allowing it to better clean stubborn residues, such as hardened dough pieces, resulting in a more thorough cleaning and reducing the mixing of dough with impurities during transport. The scraper 23 contacts the roller surface at a 15°-45° angle, balancing cleaning effectiveness with wear. Furthermore, the inclined design of the chute 211 prevents collisions with the scraper 23, avoiding noise, and also prevents the scraper 23 from falling into the chute 211 and affecting the normal rotation of the pressing roller 22.

[0033] Furthermore, such as Figure 2 , Figure 6 As shown, since the dough is in the form of dough before being conveyed, in order to give the dough downward conveying pressure, a pressure knife 24 is provided above the first dough pressing mechanism 2. The pressure knife 24 is located directly above the two dough pressing rollers 22. A first driving member 12 is provided on the frame 1. The output shaft 121 of the first driving member 12 is connected to the pressure knife 24 and is used to drive the pressure knife 24 to move up and down relative to the first dough pressing mechanism 2.

[0034] Specifically, the frame 1 is provided with a base plate 15 that is perpendicular to the horizontal plane. One side of the base plate 15 is used to install each conveyor belt and the dough pressing mechanism, and the other side is used to install each driving component. The output end of the driving component passes through the base plate 15 and connects to each conveyor belt and the dough pressing mechanism. This makes the forming trajectory of the dough and the position of the driving component located on both sides of the base plate 15, thereby isolating the two and preventing flour or scraps of dough used in the production process from falling on the driving component, which would affect the normal use of the driving component and increase the difficulty of cleaning.

[0035] Furthermore, the base plate 15 is provided with an elongated opening 151 perpendicular to the horizontal plane. The upper end of the pressure knife 24 is connected to a first connecting plate 241, which passes through the elongated opening 151. One end of the first connecting plate 241 is connected to the pressure knife 24, and the other end is connected to the output shaft 121 of the first driving member 12. To improve the balance and stability of the movement of the pressure knife 24, the base plate 15 is also provided with two slide rails 152 on the other side away from the pressure knife 24. The two slide rails 152 are respectively located on both sides of the elongated opening 151. The two slide rails 152 are also provided with sliders 153. The sliders 153 on both sides are connected to a second connecting plate 154. The second connecting plate 154 is perpendicular to the first connecting plate 241. One side of the second connecting plate 154 is screwed to the output shaft 121 of the first driving member 12, and the other side is screwed to the first connecting plate 241, thereby realizing the connection between the first driving member 12 and the pressure knife 24. The structure is simple and easy to process. By setting the slide rail 152 and the slider 153, the rigidity of the connection between the output shaft of the first drive member 12 and the pressure knife 24 can be enhanced, preventing the pressure knife 24 from shifting or deforming when pressing the dough, and enhancing the stability of the pressure knife 24.

[0036] Preferably, the end of the pressing blade 24 that contacts the dough has a cylindrical structure, which increases the contact area with the dough and allows the blade of the pressing blade 24 to move to the position closest to the tangent point of the two pressing rollers 22. This allows the dough to be output in sheet form under the downward vertical pressure of the pressing blade 24 as the two pressing rollers 22 rotate. Since there is significant resistance when the dough is output from a block to a sheet during the initial pressing, the dough sheet is relatively thick during the initial pressing to ensure smooth dough transport and reduce pressing resistance. Therefore, it needs to be continuously pressed by multiple subsequent pressing mechanisms to adjust the thickness of the dough sheet.

[0037] It should be noted that the distance between the two pressing rollers 22 of each pressing mechanism is set to become increasingly narrow, so that the thickness of the dough gradually decreases after passing through each pressing mechanism, and finally the dough is rolled to form a suitable thickness. The distance between the two pressing rollers 22 can be fixed or an adjustment component can be set on each pressing mechanism to facilitate the adjustment of the distance between the two pressing rollers 22 at any time, so as to realize the production of dough of various thicknesses and meet the taste needs of different users.

[0038] Furthermore, such as Figure 7As shown, the base plate 15 of the frame 1 is also provided with a second driving member 13. One or more second driving members 13 can be provided. The output end of the second driving member 13 is provided with a driving gear 131. Each of the pressing rollers 22 and the conveyor belt has a driven gear 14 on its rotating shaft. Through the meshing connection of the driving gear 131 and the driven gear 14, the power is transmitted step by step to all components that need to be synchronized, ensuring that the dough is rolled and conveyed at the same speed. At the same time, through the meshing of the driving gear 131 and each driven gear 14, the transmission of one driving member to drive multiple pressing rollers 22 and conveyor belts can be realized. This can reduce the number of driving members, thereby reducing the complexity and cost of the internal structure, avoiding energy redundancy loss when each part is driven independently, making the structure of this utility model simpler and occupying less space overall.

[0039] Furthermore, such as Figure 8 As shown, a first conveyor belt 25 is provided between the first dough pressing mechanism 2 and the second dough pressing mechanism 3. The first conveyor belt 25 includes a transverse conveyor belt 251 and a longitudinal conveyor belt 252. The transverse conveyor belt 251 is located below the discharge end of the first dough pressing mechanism 2, and the discharge end of the transverse conveyor belt 251 corresponds to the inlet end of the longitudinal conveyor belt 252. The discharge end of the longitudinal conveyor belt 252 corresponds to the inlet end of the second dough pressing mechanism 3. Thus, the dough sheet conveyed vertically downward by the first dough pressing mechanism 2 changes its conveying direction under the conveying of the transverse conveyor belt 251 and the longitudinal conveyor belt 252. The transverse conveyor belt 251 is composed of several conveying rollers, which only need to provide a supporting and conveying force to the dough sheet. The longitudinal conveyor belt 252 is provided with several racks 2521 to increase the friction of the dough sheet in the longitudinal direction, so that it can move with the rotation of the longitudinal conveyor belt 252.

[0040] Furthermore, such as Figure 9 As shown, the dough sheet output from the longitudinal conveyor belt 252 enters the second pressing mechanism 3, and its thickness is adjusted and thinned a second time under the rolling of the two pressing rollers 22 of the second pressing mechanism 3. The dough sheet output from the second pressing mechanism 3 continues to be conveyed to the third pressing mechanism 4. In one embodiment of this utility model, a second conveyor belt 31 is provided between the second pressing mechanism 3 and the third pressing mechanism 4. The second conveyor belt 31 is inclined upward from the second pressing mechanism 3 to the third pressing mechanism 4. The two ends of the second conveyor belt 31 correspond to the discharge end of the second pressing mechanism 3 and the inlet end of the third pressing mechanism 4, respectively. The second conveyor belt 31 has the function of supporting the dough sheet to prevent the dough sheet from breaking or sagging during the conveying process to the third pressing mechanism 4, which would affect the normal conveying. Furthermore, the discharge end of the second conveyor belt 31 is provided with a turning platform 311 parallel to the horizontal plane. The turning platform 311 is located above the third dough pressing mechanism 4 and corresponds to the inlet of the third dough pressing mechanism 4. This allows the dough sheets, which are being conveyed at an upward inclination, to enter the third dough pressing mechanism 4 at a downward angle of 90° after passing through the turning platform 311, thus achieving vertical conveying of the dough sheets from top to bottom. The setting of the turning platform 311 has a guiding effect on the turning of the dough sheets, so that the angle of the upward inclination of the dough sheets gradually changes to being parallel to the horizontal plane, and then achieves vertical conveying downward. This provides a transition stage for the turning of the dough sheets. If the turning platform 311 is not provided, the second conveyor belt 31 will directly enter the third dough pressing mechanism 4 vertically downward in the inclination conveying direction, which will easily form a sharp angle at the turning point. This angle can easily cut the dough sheets, causing them to break and thus interrupting the normal production of dumplings.

[0041] Preferably, an independent auxiliary roller 32 is provided between the second dough pressing mechanism 3 and the second conveyor belt 31. The auxiliary roller 32 can actively pull the dough by rotating, ensuring that the dough enters the second conveyor belt 31 in a flat and wrinkle-free state, avoiding deformation or displacement due to uneven pulling. On the other hand, it can apply appropriate tension to the dough by adjusting the distance or pressure between the auxiliary roller and the second conveyor belt 31, ensuring that the dough remains taut during the conveying process, avoiding inaccurate positioning caused by slack (such as affecting subsequent filling or forming stations).

[0042] Furthermore, such as Figure 3 , Figure 10 , Figure 11 As shown, after being rolled by the third dough pressing mechanism 4, a large amount of flour that was originally left on the dough will be incorporated into the dough or remain on the conveyor belt or pressing roller 22. Therefore, to prevent the dough from sticking when it continues to be conveyed to the fourth dough pressing mechanism 5, a third conveyor belt 41 is provided between the third dough pressing mechanism 4 and the fourth dough pressing mechanism 5. The third conveyor belt 41 is located below the third dough pressing mechanism 4, with one end corresponding to the discharge port of the third dough pressing mechanism 4 and the other end corresponding to the inlet of the fourth dough pressing mechanism 5. A flour spraying device 6 is provided above both ends of the conveyor belt 41. The flour spraying device 6 includes a flour hopper 61, a roller 62, and a hopper cover 63. The bottom of the flour hopper 61 has several holes 611. The roller 62 rotates inside the flour hopper 61 to evenly distribute the flour through the holes 611 onto the third conveyor belt 41, preventing the flour from accumulating on the holes 611 and causing blockage. The hopper cover 63 covers the flour hopper 61 to prevent the flour from flying out of the flour hopper 61 and causing dust pollution when the roller 62 rotates.

[0043] Specifically, after the dough comes out of the third pressing mechanism 4, it falls onto the third conveyor belt 41. Its lower end will contact the third conveyor belt 41 and thus pick up the flour that has fallen onto the third conveyor belt 41, which can prevent the dough from sticking to the conveyor belt. Then, the dough will pass under another flour spraying device 6, and the flour sprayed by the flour spraying device 6 will directly fall onto the upper end of the dough, so that both the upper and lower ends of the dough are covered with flour, preventing the dough from entering the fourth pressing mechanism 5 and sticking to the pressing roller 22.

[0044] Preferably, to ensure the uniformity of the flour sprinkled on the third conveyor belt 41 and the dough, brushes 64 are provided in front of both flour spraying devices 6 along the conveying direction. If there are clumps or damp flour at the outlet of the flour hopper 61, the oscillation of the brushes 64 can break up the clumps, so that the flour sprinkled on the third conveyor belt 41 and the dough is evenly spread, avoiding flour accumulation or uneven distribution, and ensuring that the conveyor belt or the surface of the dough is covered with a thin and uniform layer of flour to prevent sticking. At the same time, it can also remove excess flour from the conveyor belt to prevent the flour from being too thick, affecting the dough rolling effect or causing waste.

[0045] Preferably, a tray 65 adapted to the length of the third conveyor belt 41 is provided below the third conveyor belt 41, so that any flour residue falling on the third conveyor belt 41 can fall onto the tray 65 when conveyed downwards, avoiding it from falling on other parts, increasing cleaning difficulty, and affecting the normal operation of the machine. At the same time, the flour falling on the tray 65 can be recycled for reuse, reducing waste and saving costs. A support frame is screwed onto the base plate 15, and the tray 65 can be removed from the support frame at any time for convenient use.

[0046] Furthermore, auxiliary roller 2 42 and auxiliary roller 3 43 are respectively provided above the third conveyor belt 41 and at the discharge end. After the dough is output from between the two pressing rollers 22 of the third pressing mechanism 4, it passes through the lower end of the auxiliary roller 2 42 from the side, ensuring effective contact between the dough and the third conveyor belt 41, thereby increasing the friction between the dough and the third conveyor belt 41, and thus making the flour stick to the dough more smoothly. Then, after the dough is output, it abuts against the upper end of the auxiliary roller 3 43 and enters the fourth pressing mechanism 5. The setting of the auxiliary roller 2 42 and the auxiliary roller 3 43 ensures that the dough is smoothly conveyed in the set conveying direction, avoiding inaccurate positioning caused by slack, and at the same time, laying the foundation for smooth subsequent rolling.

[0047] Furthermore, such as Figure 2As shown, a fourth conveyor belt 51 is also provided on the base plate 15. The fourth conveyor belt 51 is located below the fourth dough pressing mechanism 5, so that the dough after being pressed by the fourth dough pressing mechanism 5 is conveyed by the fourth conveyor belt 51 into the subsequent trimming, filling and sealing stages. Similarly, in order to avoid the dough sticking to the fourth conveyor belt 51, the flour spraying device 6, the brush 64 and the tray 65 are also provided on the fourth conveyor belt 51. The flour spraying device 6 directly sprinkles flour onto the fourth conveyor belt 51, so that the lower surface of the dough can be coated with flour when it falls onto the fourth conveyor belt 51. Since the upper surface of the dough is used for filling at this time, the upper surface of the dough does not need to be coated with flour.

[0048] As shown in the figure, each dough pressing mechanism and each conveyor belt form an approximately circular conveying structure on the base plate, and the center of the circle is used to set up the feeding area 11 and the flour spraying device 6. This makes full use of the space layout, making the connection structure between the mechanisms more compact. The compact design can also reduce the weight and volume of the equipment, and facilitate transportation, installation or adjustment of the production line layout.

[0049] The working principle of this utility model is explained in detail below: In use, the dough is placed in the feeding area 11 above the first pressing mechanism 2, and the pressing blade 24 is driven to squeeze the dough, so that the dough is exported in a long strip shape between the two pressing rollers 22 of the first pressing mechanism 2. When using it for the first time, the long strip of dough needs to be manually pulled to each pressing mechanism to ensure that the dough is automatically conveyed on the machine. Then, the dough that has been pressed by the first pressing mechanism 2 will automatically pass through the first conveyor belt 25, the second pressing mechanism 3, the second conveyor belt 31, the third pressing mechanism 4, the third conveyor belt 41 and the fourth pressing mechanism 5 in sequence. Under the pressing of each pressing mechanism, a dough sheet of moderate thickness and uniformity is finally output.

[0050] The innovation of this utility model lies in the circular arrangement of the first, second, third, and fourth pressing mechanisms, which enables the dough to be automatically output as sheet form, reduces the space occupied in the horizontal and vertical directions, makes the connection between the structures more compact, makes fuller use of space, and facilitates storage and transportation. In addition, the first pressing mechanism is located at the bottom and is connected to the feeding area, realizing a bottom-up conveying structure for the sheet. This not only makes the feeding position more convenient, but also allows the height of the discharge position to be better coordinated with other subsequent mechanisms, giving this utility model the characteristics of simple structure and small space occupation.

[0051] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.

[0052] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
