Description

Technical Field

[0001] This disclosure relates to the field of dough knives, and more particularly to a dough knive, a mixing device, a noodle machine, and a method for preparing pasta. Background Technology

[0002] The existing noodle machine's kneading blade mainly uses a single-sided kneading operation. That is, during the kneading process, the same side of the kneading blade has to handle both the stirring of flour clumps and the extrusion of dough to complete the production of a whole dough.

[0003] Therefore, when the load of agitation and extrusion is concentrated on the same side of the dough mixer, it is easy to cause fatigue damage to the dough mixer, which in turn affects the service life of the dough mixer. Summary of the Invention

[0004] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this disclosure provides a dough mixer, a mixing device, a noodle machine, and a method for preparing pasta.

[0005] In a first aspect, this disclosure provides a dough kneading knife, including a rotating connecting portion and a stirring blade body and a pressing blade body disposed on the rotating connecting portion, wherein the stirring blade body and the pressing blade body are distributed at intervals along the circumferential direction of the rotating connecting portion;

[0006] A mixing working surface is formed on the body of the mixing blade; the mixing working surface is used to mix water and flour when the dough kneading blade rotates;

[0007] The end face of the extrusion blade body facing away from the rotating connection part forms an extrusion working surface, which is used together with the inner wall of the container where the dough kneading blade is located to extrude the dough formed by mixing.

[0008] At least a portion of the mixing working surface and / or at least a portion of the extrusion working surface are smooth surfaces.

[0009] The dough mixer blade disclosed herein comprises a mixing blade body and an extrusion blade body. The mixing blade body has a mixing surface for mixing water and flour, and the end face of the extrusion blade body away from the rotating connection portion has an extrusion surface for extruding the dough formed by mixing. This allows for the mixing and extrusion of flour into a dough by utilizing different surfaces on the mixing and extrusion blade bodies. In other words, the load required for mixing and extrusion is distributed across different sides of the dough mixer blade, avoiding the problem of fatigue damage caused by concentrating the mixing and extrusion loads on a single side of the blade, thus affecting its lifespan. Furthermore, by ensuring that at least part of the mixing surface and / or at least part of the extrusion surface are smooth, the mixing and extrusion surfaces are easy to clean, and the accumulation of flour and other materials on these surfaces can be prevented to some extent.

[0010] According to one embodiment of this disclosure, at least a portion of the stirring working surface is a smooth plane and / or at least a portion of the extrusion working surface is a smooth plane.

[0011] In this technical solution, by setting at least part of the mixing working surface and at least part of the extrusion working surface to be smooth planes, the mixing force on the flour or dough on the mixing working surface or the extrusion force on the dough on the extrusion working surface can be more balanced, and the accumulation of flour or other materials on the mixing working surface or the extrusion working surface can be avoided to a certain extent. In addition, the mixing working surface and the extrusion working surface can be easily cleaned.

[0012] According to one embodiment of this disclosure, the included angle between the stirring blade body and the extrusion blade body along the circumferential direction of the rotating connection portion ranges from 90° to 180°.

[0013] In this technical solution, by reasonably setting the included angle range between the mixing blade body and the extrusion blade body along the circumferential direction of the rotating connection, the mixing blade body and the extrusion blade body are relatively distributed on both sides of the rotating connection, thereby making the force on both sides of the rotating connection more uniform and avoiding fatigue damage to the dough knives.

[0014] According to one embodiment of this disclosure, the front side of the mixing blade body along the rotation direction of the dough kneading blade is formed as the mixing working surface.

[0015] In this technical solution, the front side of the mixing blade body along the rotation direction of the dough kneading blade can be set to form a mixing working surface, so that the mixing working surface can fully mix water and flour.

[0016] According to one embodiment of this disclosure, the side of the mixing blade body facing away from the mixing working surface is a smooth surface; and / or, the side of the extrusion blade body facing the mixing working surface and / or the side facing away from the mixing working surface along the rotation direction of the dough kneading blade is a smooth surface.

[0017] In this technical solution, by setting the side of the mixing blade body away from the mixing working surface to be a smooth surface; and / or, setting the side of the extrusion blade body facing the mixing working surface and / or the side away from the mixing working surface along the rotation direction to be a smooth surface, it is possible to reduce the deposition of flour and other substances on its sides and facilitate cleaning.

[0018] According to one embodiment of the present disclosure, at least a portion of the extrusion blade body is inclined in a direction away from the rotation axis of the rotating connection in the direction from the top to the bottom of the dough knives.

[0019] In this technical solution, by setting the extrusion blade body to be inclined in the direction away from the rotation axis of the rotating connection, the distance between the end face of the extrusion blade body away from the rotating connection and the inner wall of the container gradually increases in the direction from the bottom to the top of the dough kneading blade, thereby accommodating and extruding larger dough balls.

[0020] According to one embodiment of the present disclosure, the extrusion blade body includes a first extrusion blade body segment and a second extrusion blade body segment connected to the bottom end of the first extrusion blade body segment;

[0021] In the direction from the top to the bottom of the dough knives, the first extrusion blade body segment is inclined in a direction away from the rotation axis of the rotating connection; and / or, the second extrusion blade body segment extends in a vertical direction.

[0022] In this technical solution, by tilting the first extrusion blade body segment away from the rotation axis of the rotating connection, the distance between the end face of the first extrusion blade body segment away from the rotating connection and the inner wall of the container gradually increases from the bottom to the top of the dough-making blade, thereby accommodating and extruding larger dough balls. By setting the second extrusion blade body segment to extend vertically, smaller dough balls can be easily extruded, which is more conducive to subsequently extruding smaller dough balls together with larger dough balls, thus facilitating the formation of a complete large dough ball.

[0023] In this technical solution, according to one embodiment of the present disclosure, the height of the first extrusion blade body section ranges from 10mm to 80mm in the direction from the top to the bottom of the dough knives, and the height of the second extrusion blade body section ranges from 5mm to 30mm.

[0024] In this technical solution, by reasonably setting the height dimensions of the first extrusion blade body section and the second extrusion blade body section, it is beneficial for the first extrusion blade body section to extrude larger dough balls, while the second extrusion blade body section extrudes smaller dough balls, thereby subsequently extruding and shaping a complete large dough ball.

[0025] According to one embodiment of this disclosure, the distance between the extrusion working surface and the rotation axis gradually decreases along the rotation direction of the dough-mixing knife.

[0026] In this technical solution, by setting the distance between the extrusion working surface and the rotation axis to gradually decrease, it is beneficial for the extrusion blade body to extrude the dough during rotation.

[0027] According to one embodiment of the present disclosure, one end of the mixing blade body is connected to the rotating connection portion, and at least a portion of the mixing blade body is inclined along the rotation axis away from the rotating connection portion in the direction from the top to the bottom of the dough kneading blade.

[0028] In this technical solution, by setting the mixing blade in the direction from top to bottom, at least part of the mixing blade body is tilted in a direction away from the rotation axis of the rotating connection, so that the mixing blade body can fully stir the flour at the bottom of the container, thereby mixing the flour with water.

[0029] According to one embodiment of the present disclosure, the mixing blade body includes a first mixing blade body segment and a second mixing blade body segment connected to the bottom of the first mixing blade body segment; the first mixing blade body segment is inclined in a direction away from the rotation axis along the direction from the top to the bottom of the dough kneading blade.

[0030] In this technical solution, by setting the dough knives from top to bottom, the first mixing blade body section is inclined in a direction away from the rotation axis of the rotating connection, thereby enabling the first mixing blade body section to effectively stir the flour in the container, thus mixing the flour with water.

[0031] According to one embodiment of this disclosure, the second stirring blade body segment extends in the horizontal reverse direction.

[0032] In this technical solution, by setting the second stirring blade body section to extend horizontally, the flour at the bottom of the container can be effectively stirred, so that the flour and water can be fully mixed together.

[0033] According to one embodiment of this disclosure, the height of the second stirring blade body segment gradually decreases in the vertical direction from one end of the second stirring blade body segment near the rotating connection portion to the other end of the second stirring blade body segment away from the rotating connection portion.

[0034] In this technical solution, by setting the height of the second stirring blade body segment in the vertical direction to gradually decrease from the end near the rotating connection to the end away from the rotating connection, the injection molding of the second stirring blade body segment can be facilitated.

[0035] According to one embodiment of this disclosure, the height of the second stirring blade body segment in the vertical direction ranges from 3mm to 20mm; and / or, the distance between the portion of the stirring working surface located on the second stirring blade body segment and the side of the second stirring blade body segment opposite to the stirring working surface ranges from 5mm to 30mm.

[0036] In this technical solution, by reasonably setting the height dimension of the second stirring blade body section in the vertical direction, the second stirring blade body section has sufficient height dimension to meet the strength requirements.

[0037] By reasonably setting the distance between the mixing working surface of the second mixing blade body section and the side opposite to the mixing working surface, the second mixing blade body section has sufficient thickness to meet the strength requirements.

[0038] According to one embodiment of this disclosure, the top of the rotating connection portion protrudes away from the bottom of the rotating connection portion to form an arc-shaped protrusion or a sharp-angled protrusion.

[0039] In this technical solution, by setting the top of the rotating connector to protrude in a direction away from the bottom to form an arc-shaped protrusion or a sharp-angled protrusion, the flour can be prevented from accumulating on the top of the rotating connector when it is poured into the container.

[0040] Secondly, this disclosure provides a mixing device, including a container, a driving assembly, and a dough-kneading blade disposed within the container; the driving assembly is used to drive the rotating connection portion to rotate.

[0041] In this technical solution, a drive component is set to drive the rotating connection part to rotate, thereby driving the mixing blade body and the extrusion blade body to rotate, so that the water and flour in the container are stirred by the mixing blade body and the extrusion blade body, and the dough is extruded by the extrusion blade body to form a large dough.

[0042] According to one embodiment of this disclosure, the drive assembly includes a drive motor and a gearbox. One end of the gearbox is connected to the output shaft of the drive motor, and the other end of the gearbox is connected to the rotating connection portion. The gearbox is used to drive the rotating connection portion to rotate under the drive of the drive motor.

[0043] In this technical solution, a drive motor drives a gearbox, which in turn drives the rotating connection part to rotate, thereby driving the mixing blade body and the extrusion blade body to rotate. The mixing blade body and the extrusion blade body can stir the water and flour in the container, and the extrusion blade body can extrude the stirred dough to form a large dough ball.

[0044] According to one embodiment of the present disclosure, the extrusion blade body includes a first extrusion blade body segment and a second extrusion blade body segment connected to the bottom end of the first extrusion blade body segment.

[0045] According to one embodiment of this disclosure, the gap between the end face of the second extrusion blade body segment away from the rotating connection portion and the inner wall of the container ranges from 1mm to 30mm.

[0046] By reasonably setting the gap range between the end face of the second extrusion blade body section away from the rotating connection part and the inner wall of the container, an extrusion cavity that can accommodate a dough of an appropriate size is formed between the end face of the second extrusion blade body section away from the rotating connection part and the inner wall of the container, and then the dough is extruded into a ball through the extrusion cavity.

[0047] According to one embodiment of this disclosure, the distance between the extrusion working surface and the rotation axis gradually decreases along the rotation direction of the dough-mixing knife;

[0048] The angle between the portion of the extrusion working surface located in the first extrusion blade body section and the inner wall of the container ranges from 5° to 60°; and / or,

[0049] The angle between the portion of the extrusion working surface located in the second extrusion blade body section and the inner wall of the container ranges from 5° to 60°.

[0050] In this technical solution, by setting the distance between the extrusion working surface and the rotation axis to gradually decrease, it is beneficial for the extrusion blade body to extrude the dough during rotation.

[0051] According to one embodiment of this disclosure, in the direction from the top to the bottom of the extrusion blade body, the distance between the top of the extrusion working surface and the inner wall of the container is greater than the distance between the bottom of the extrusion working surface and the inner wall of the container.

[0052] In this technical solution, by setting the distance between the top of the extrusion working surface and the inner wall of the container in the direction from the top to the bottom of the extrusion blade body, the distance between the top of the extrusion working surface and the inner wall of the container is greater than the distance between the bottom of the extrusion working surface and the inner wall of the container, so that an extrusion cavity that can accommodate a larger dough can be formed between the extrusion working surface and the inner wall of the container, thereby extruding a larger dough to form a complete large dough.

[0053] According to one embodiment of this disclosure, the distance between the side of the extrusion blade body facing the stirring working surface and the side of the extrusion blade body facing away from the stirring working surface ranges from 5mm to 30mm; and / or, the gap between the bottom of the extrusion blade body and the bottom wall of the container ranges from 1mm to 30mm.

[0054] In this technical solution, by reasonably setting the distance between the side of the extrusion blade body facing the mixing working surface and the side facing away from the mixing working surface, the extrusion blade body has sufficient thickness, thereby having good strength and fatigue resistance.

[0055] By properly setting the gap between the bottom of the extrusion blade and the bottom wall of the container, not only can the extrusion blade be used to extrude smaller dough balls, but the container can also be prevented from interfering with the rotation of the extrusion blade.

[0056] According to one embodiment of the present disclosure, the stirring blade body includes a first stirring blade body segment and a second stirring blade body segment connected to the bottom of the first stirring blade body segment;

[0057] The gap between the bottom surface of the second stirring blade body section and the bottom wall of the container is in the range of 1mm-30mm; and / or, the gap between the end face of the second stirring blade body section away from the rotating connection and the inner wall of the container is in the range of 2mm-30mm.

[0058] In this technical solution, by reasonably setting the gap between the bottom surface of the second mixing blade body section and the bottom wall of the container, the second mixing blade body section can effectively stir the flour at the bottom of the container, so that the water and flour are fully mixed, which is beneficial for subsequent extrusion into dough.

[0059] By properly setting the gap between the end face of the second mixing blade body section away from the rotating connection and the inner wall of the container, the second mixing blade body section can be fully mixed with the flour, and the container can also be ensured that it does not interfere with the rotation of the second mixing blade body section.

[0060] Thirdly, this disclosure provides a noodle machine, including a base and a mixing device;

[0061] The stirring device is mounted on the machine base.

[0062] According to one embodiment of this disclosure, the noodle machine further includes a water tank assembly and a water pump assembly, the water pump assembly being located on the side of the water tank assembly closer to the container; the water pump assembly is connected to both the water tank assembly and the container, so that water in the water tank assembly enters the container via the water pump assembly;

[0063] The noodle machine also includes an extrusion assembly, which is disposed on the container and communicates with the inner cavity of the container. The drive assembly is used to drive part of the extrusion assembly to rotate in order to extrude the dough that has been mixed and shaped.

[0064] The extrusion assembly includes an extrusion cylinder, an extrusion screw, and an extrusion die. The extrusion cylinder is disposed on the container and communicates with the inner cavity of the container. The extrusion die is disposed at the end of the extrusion cylinder away from the container. The extrusion screw is disposed inside the extrusion cylinder and connected to the drive assembly. The drive assembly is used to drive the extrusion screw to rotate so that the dough entering the extrusion cylinder is extruded through the extrusion die.

[0065] The die head is located on the bottom surface of the extrusion cylinder.

[0066] In this technical solution, by setting up a water tank component, water can be supplied to the container, so that the flour in the container can be mixed, stirred and extruded with an appropriate proportion of water to form a complete dough.

[0067] By setting up an extrusion component, the dough that has been mixed and extruded can be extruded to complete the dough-making process.

[0068] Fourthly, this disclosure provides a method for preparing pasta using a noodle machine, the method comprising:

[0069] Add water and flour to the container in the preset mass ratio;

[0070] The dough-mixing blade is driven to rotate in a first rotational direction, so that the water and flour are mixed under the action of the mixing blade body and the extrusion blade body to form at least a first dough; and the extrusion blade body extrudes the multiple first doughs formed by the mixture to form a second dough, wherein the second dough is larger than the first dough; or,

[0071] The dough-mixing blade is driven to rotate in a first rotation direction so that the water and flour are mixed under the action of the mixing blade body and the extrusion blade body and at least form dough flakes; the extrusion screw in the extrusion cylinder connected to the container is driven to rotate in a second rotation direction so that the dough flakes entering the extrusion cylinder are moved to the dough exiting die head by the extrusion screw and extruded by the dough exiting die head to form a dough product; wherein, the first rotation direction is opposite to the second rotation direction.

[0072] In this technical solution, water and flour in a preset mass ratio are added to a container, and the water and flour are mixed by the mixing blade and the extrusion blade. The first dough formed by the mixture is then extruded by the extrusion blade to form a larger second dough, thereby realizing the dough making operation. Alternatively, water and flour can be mixed by the mixing blade and the extrusion blade to form dough flakes, and the dough flakes entering the extrusion cylinder can be moved by the extrusion screw to the dough exit die head for extrusion molding, thereby completing the preparation of dough products.

[0073] According to one embodiment of this disclosure, prior to the step of driving the dough-mixing blade to rotate in a first rotational direction so that the water and flour are mixed under the action of the mixing blade body and the extrusion blade body and at least form a first dough, the preset mass ratio of water and flour added to the container is in the range of 35%-60%.

[0074] In this technical solution, by setting a reasonable ratio of water and flour, it is easier to process the required second dough through subsequent mixing.

[0075] According to one embodiment of this disclosure, before the step of driving the dough-mixing blade to rotate in a first rotational direction so that the water and flour are mixed under the action of the mixing blade body and the extrusion blade body and at least form dough flakes, the preset mass ratio of water and flour added to the container is in the range of 30%-40%.

[0076] In this technical solution, by setting a reasonable ratio of water and flour, it is easier to mix and form dough flakes, and then extrude the dough flakes to form the desired dough products.

[0077] According to one embodiment of this disclosure, the step of driving the dough-mixing blade to rotate in a first rotational direction so that the water and flour are mixed under the action of the mixing blade body and the extrusion blade body to form at least a first dough; and having the extrusion blade body extrude the mixed first dough to form a second dough includes:

[0078] The dough-mixing blade is driven to rotate in a first rotation direction so that the water and flour are mixed under the action of the mixing blade body and the extrusion blade body to form at least dough flakes and the first dough; and the dough flakes and the flour remaining in the container are mixed under the action of the mixing blade body and the extrusion blade body to form the first dough: wherein the first dough includes a first sub-dough and a second sub-dough, and the first sub-dough is smaller than the second sub-dough;

[0079] The portion of the extrusion blade body near the bottom of the container is used to extrude the first sub-dough, while the portion of the extrusion blade body away from the bottom of the container is used to extrude the second sub-dough, so that the first sub-dough and the second sub-dough are extruded to form the second dough.

[0080] In this technical solution, water and flour are thoroughly mixed by the mixing blade and the extrusion blade, so that water and flour are completely mixed to form a first dough. Then, the smaller first sub-dough and the larger second sub-dough in the first dough are effectively extruded by the part of the extrusion blade near the bottom of the container and the part of the extrusion blade away from the bottom of the container, so that several first doughs of different sizes and shapes are finally extruded and combined to form a complete larger second dough.

[0098] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0099] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0100] Example 1

[0101] Reference Figures 1 to 10 As shown, this embodiment provides a dough kneading knife, including a rotating connecting part 100, a mixing blade body 200, and a pressing blade body 300. The mixing blade body 200 and the pressing blade body 300 are distributed at intervals along the circumference of the rotating connecting part 100, so that the mixing blade body 200 and the pressing blade body 300 are distributed at different positions in the circumference of the rotating connecting part 100. Therefore, when the mixing blade body 200 is mixing water and flour and thus bearing a load, and the pressing blade body 300 is pressing dough and thus bearing a load, the load borne by the mixing blade body 200 and the load borne by the pressing blade body 300 can be distributed at different positions in the circumference of the rotating connecting part 100, so as to avoid the load being concentrated on the same side of the rotating connecting part 100, which would easily cause the dough kneading knife to fatigue and be damaged.

[0102] Specifically, the rotating connection part 100 can be shaped as follows: Figure 1 The cylindrical structure shown has a through hole at the bottom into which the drive shaft of the drive assembly can extend, thus connecting to the drive assembly. The mixing blade body 200 and the extrusion blade body 300 are located on both sides of the rotating connection part 100 and connected to the rotating connection part 100. Thus, when the drive assembly drives the rotating connection part 100 to rotate in the direction of rotation (e.g., clockwise), it can drive the mixing blade body 200 and the extrusion blade body 300 to rotate simultaneously. This fully mixes the water and flour added to the container 400 where the dough kneading blade is located and forms several small dough balls. The extrusion blade body 300 further extrudes and shapes the mixed small dough balls, so that the several small dough balls are finally combined to form a complete large dough ball 500.

[0103] In practice, the rotating connecting part 100, the stirring blade body 200, and the extrusion blade body 300 can be integrally molded to save on processes and ensure overall structural strength. Alternatively, the rotating connecting part 100, the stirring blade body 200, and the extrusion blade body 300 can be molded separately and then bonded or welded together to form a whole.

[0104] In addition, the rotating connecting part 100, the stirring blade body 200 and the extrusion blade body 300 can all be made of plastic, ceramic or metal.

[0105] Since the mixing blade body 200 and the extrusion blade body 300 are used for mixing and extrusion respectively, the load of mixing and extruding the flour into a dough during kneading is borne by the mixing blade body 200 and the extrusion blade body 300 respectively. Therefore, compared to the mixing and extrusion loads being concentrated on the same side of a single kneading blade, different parts of the kneading blade in this embodiment are used to bear the corresponding loads respectively, so that the load borne by each part is relatively small. In other words, even if it is made of plastic, it can meet the strength and rigidity requirements.

[0106] Alternatively, to further enhance the mixing or extrusion effect and avoid fatigue damage due to excessive load, two or more mixing blade bodies 200 and extrusion blade bodies 300 can be provided. These two or more mixing blade bodies 200 and extrusion blade bodies 300 can be spaced apart circumferentially along the rotating connection portion 100, specifically, they can be evenly spaced. For example, two mixing blade bodies 200 and two extrusion blade bodies 300 can each be provided, and they can be arranged in a one-to-one correspondence.

[0107] In a specific implementation, the included angle between the stirring blade body 200 and the extrusion blade body 300 along the circumference of the rotating connection portion 100 can be between 90° and 180°. That is, when the included angle is 180°, it can be understood that the stirring blade body 200 and the extrusion blade body 300 are located on the same plane in the radial direction of the rotating connection portion 100, so that the positions of the stirring blade body 200 and the extrusion blade body 300 relative to the rotating connection portion 100 are symmetrical, thereby making the load borne by the stirring blade body 200 and the load borne by the extrusion blade body 300 more evenly distributed on the opposite sides of the rotating connection portion 100.

[0108] Wherein, along the rotation direction of the dough-mixing knife (in this embodiment, the rotation direction can be, for example, the rotation direction can be...) Figure 2 As shown in direction s1 (which can be clockwise), the front side of the mixing blade body 200 forms a mixing working surface 210. When the mixing blade body 200 rotates along the rotation direction, the mixing working surface 210 of the mixing blade body 200 contacts the flour, thereby turning or mixing the flour. For details on the specific mixing working surface 210 of the mixing blade body 200, please refer to... Figure 2 The upper surface of the stirring blade body 200 is shown. Similarly, the side of the stirring blade body 200 opposite to the stirring working surface 210 is the back side of the stirring blade body 200. Similarly, the side of the extrusion blade body 300 closest to the stirring working surface 210 of the stirring blade body 200 is the back side of the extrusion blade body 300, while the side of the extrusion blade body 300 furthest from the stirring working surface 210 of the stirring blade body 200 is the front side of the extrusion blade body 300.

[0109] Among them, one end face of the extrusion blade body 300 away from the rotating connection part 100 forms an extrusion working surface 310, i.e., refer to Figure 2 As shown in the drawing orientation, the right end face of the extrusion blade body 300 is formed as an extrusion working surface 310. During dough kneading, the right end face of the extrusion blade body 300 and the inner wall of the container 400 form an extrusion cavity, thereby extruding the dough formed by the mixing blade body 200 and / or the extrusion blade body 300, so that multiple small dough balls of different sizes are finally extruded into a complete large dough ball 500 to complete the dough kneading operation.

[0110] In addition, by setting at least part of the mixing working surface 210 and / or at least part of the extrusion working surface 310 to be smooth surfaces, the mixing and extrusion of flour or dough can be more evenly distributed. This not only makes it easier to clean the mixing working surface 210 and the extrusion working surface 310, but also prevents flour and other materials from accumulating on the mixing working surface 210 or the extrusion working surface 310 to a certain extent.

[0111] Specifically, at least part of the mixing surface 210 can be made smooth, which makes the mixing force on the flour or dough more even. This not only makes it easier to clean the mixing surface 210, but also prevents flour and other materials from accumulating on the mixing surface 210 to a certain extent.

[0112] Alternatively, at least part of the extrusion working surface 310 can be made smooth, which makes the extrusion force on the dough more even. This not only makes it easier to clean the extrusion working surface 310, but also prevents flour and other substances from accumulating on the extrusion working surface 310 to a certain extent.

[0113] Alternatively, at least part of the mixing surface 210 and at least part of the extrusion surface 310 can be made to be smooth surfaces, so that the mixing and extrusion of flour or dough are more evenly distributed. This not only makes it easier to clean the mixing surface 210 and the extrusion surface 310, but also prevents flour and other materials from accumulating on the mixing surface 210 or the extrusion surface 310 to a certain extent.

[0114] Furthermore, the mixing surface 210 may be entirely smooth, or only partially smooth. Similarly, the extrusion surface 310 may be entirely smooth, or only partially smooth.

[0115] As can be seen from the above, in this embodiment, the extrusion working surface 310 and the stirring working surface 210 of the dough kneading blade are located on different sides of the dough kneading blade, so that the flour can be stirred and extruded through different sides. This avoids the problem of concentrated load of stirring and extrusion on the same side of the dough kneading blade, which can lead to fatigue damage.

[0116] The specific dough mixing method is as follows: First, add flour to container 400, then add water according to the ratio. After adding water, the drive motor of the drive component starts, driving the dough mixing blade to rotate in the direction of rotation (e.g., clockwise) through the gearbox. Under the action of the mixing blade body 200 and the extrusion blade body 300, the water and flour begin to mix. The mixing blade body 200 is close to the bottom of container 400 and can turn over the flour located at the bottom of container 400, facilitating the mixing of the flour. The extrusion blade body 300 is higher and can turn over the water and flour located on the surface, allowing the water and flour to be initially mixed.

[0117] After the water and flour are initially mixed, they gradually form dough flakes and small dough balls during stirring. During the folding process, smaller particles sink while larger particles rise. The smaller dough balls at the bottom are compressed by the lower part of the extrusion blade 300, while the larger dough balls are compressed by the upper part of the extrusion blade 300. The flour and dough flakes are folded by the mixing blade 200, and during this folding process, the flour at the bottom gradually combines completely into dough flakes. The dough flakes and small dough balls at the bottom are gradually combined into larger dough balls under the compression of the mixing section. As the dough balls grow larger, they are compressed by the upper part of the extrusion blade 300, and with the action of the extrusion blade 300, a complete large dough ball 500 is gradually formed.

[0118] In summary, the dough kneading blade of this embodiment decomposes the dough kneading process into mixing and extrusion. A typical dough kneading blade usually uses one working part to perform both functions, which results in a relatively large load on the entire working part and requires a relatively large overall cross-sectional area. This is because if a good mixing effect is required, the blade must be close to the bottom of the bowl. When it is necessary to extrude the dough, the dough kneading blade needs to have a certain height, otherwise it will be unable to extrude the entire dough. Having one working part perform two functions will create a contradiction between effectiveness and volume.

[0119] After decomposing the two-stage work into two parts, the mixing blade body 200 and the extrusion blade body 300, the mixing blade body 200 only undertakes the mixing work. Therefore, the mixing blade body 200 can be made thin and narrow, only needing to be close to the bottom of the container 400, so as to effectively turn or stir the flour at the bottom of the container 400, so that the flour and water are fully mixed. The extrusion blade body 300 can be made higher, covering a wider area and having a better extrusion effect. That is, the extrusion working surface 310 of the extrusion blade body 300 can be set to be larger, extending from the bottom to the top of the container 400.

[0120] Furthermore, existing dough knives compress the dough by pressing it against the surface of the dough at their outer end. The compression surface is essentially the wall thickness of the dough knives. However, the existing dough knives have relatively small wall thicknesses, resulting in a small compression surface. This makes it difficult to compress the dough 500 effectively and to quickly form a complete large dough ball 500. In this solution, the dough is compressed using the compression working surface 310 of the extrusion blade body 300, resulting in a better compression effect.

[0121] In summary, the dough-mixing blade of this embodiment consists of two parts: a mixing blade body 200 and a pressing blade body 300. A drive unit rotates both the mixing blade body 200 and the pressing blade body 300 along the rotation direction to achieve flour mixing and dough pressing. Specifically, the front side of the mixing blade body 200 along the rotation direction forms a mixing working surface 210 for mixing water and flour, and the end face of the pressing blade body 300 away from the rotating connection part 100 forms a pressing working surface 310 for pressing the mixed dough. Thus, the flour mixing and dough pressing operations are achieved through different surfaces on the mixing blade body 200 and the pressing blade body 300. This distributes the load required for flour mixing and pressing operations across different sides of the dough-mixing blade, avoiding the problem of fatigue damage caused by concentrating the mixing and pressing load on the same side of the dough-mixing blade, which would affect its lifespan.

[0122] In specific implementation, at least a portion of the mixing surface 210 and at least a portion of the extrusion surface 310 can be set as smooth planes. This ensures that the mixing force on the flour or dough 500 on the mixing surface 210 or the extrusion force on the extrusion surface 310 is more balanced, facilitating cleaning and preventing flour accumulation on the mixing surface 210 or extrusion surface 310 to some extent. Alternatively, at least a portion of the mixing surface 210 and at least a portion of the extrusion surface 310 can be set as smooth arc surfaces, depending on actual needs. This embodiment does not impose specific limitations on this. That is, the mixing surface 210 can be completely flat, completely arc-shaped, or partially flat with the remaining portion being arc-shaped or inclined. Similarly, the extrusion surface 310 can be completely flat, completely arc-shaped, or partially flat with the remaining portion being arc-shaped or inclined.

[0123] Reference Figure 1 and Figure 2 As shown, along Figure 1In the z-direction shown, at least a portion of the extrusion blade body 300 segment can be configured to tilt downward to the right, such that in the direction from the bottom to the top of the dough knives, the distance between the end face of the extrusion blade body 300 away from the rotating connection portion 100, i.e. the right end face of the extrusion blade body 300, and the inner wall of the container 400 gradually decreases, so that the opening diameter of the extrusion cavity formed between the right end face of the extrusion blade body 300 and the inner wall of the container 400 gradually decreases in the direction from top to bottom, thereby accommodating and extruding a larger dough ball 500.

[0124] In practice, because the distance between the extrusion working surface 310 of the extrusion blade body 300 and the inner wall of the container 400 gradually decreases from top to bottom, when the dough 500 formed by mixing is small, the smaller dough 500 will fall into the gap between the lower end of the extrusion working surface 310 and the inner wall of the container 400. This allows the smaller dough 500 to be extruded and shaped within the extrusion cavity formed by the bottom of the extrusion working surface 310 and the inner wall of the container 400. Thus, when the smaller dough 500 is compressed, it can gradually combine to form a larger dough 500. Conversely, because the gap between the upper end of the extrusion working surface 310 and the inner wall of the container 400 is larger, the larger gap at the top ensures that the resistance during the extrusion process is not too great, and the larger dough 500 can be compressed. Therefore, after being compressed, the larger dough 500 eventually forms a complete large dough 500, thus completing the dough kneading operation.

[0125] In addition, by setting the side of the mixing blade body 200 away from the mixing working surface 210 to be a smooth surface; and / or, setting the side of the extrusion blade body 300 facing the mixing working surface 210 and / or away from the mixing working surface 210 along the rotation direction to be a smooth surface, it is possible to reduce the deposition of flour and other substances on its sides and to facilitate cleaning.

[0126] In specific implementation, refer to Figure 5 As shown, the extrusion blade body 300 is divided into two sections from top to bottom: the upper section is the first extrusion blade body section 320, and the lower section is the second extrusion blade body section 330. The second extrusion blade body section 330 is located at the bottom of the first extrusion blade body section 320, and the two sections can be integrally formed to ensure overall structural strength. Alternatively, the first extrusion blade body section 320 and the second extrusion blade body section 330 can be formed separately and then welded or bonded together. Specifically, the first extrusion blade body section 320 and the second extrusion blade body section 330 can be made of the same material, or they can be made of different materials.

[0127] Additionally, along the direction from one end of the extrusion blade body 300 near the rotating connection portion 100 to the end away from the rotating connection portion 100, i.e., referring to... Figure 1As shown in the drawing orientation, the thickness of the extrusion blade body 300 along the left-to-right direction can be set to be the same, or the thickness of the first extrusion blade body segment 320 can be set to be greater than the thickness of the second extrusion blade body segment 330, or the thickness of the first extrusion blade body segment 320 can be set to be less than the thickness of the second extrusion blade body segment 330.

[0128] Furthermore, in the direction from the top to the bottom of the dough-making knife (refer to...) Figure 5 (As shown in the z direction), the first extrusion blade body section 320 above is inclined in a direction away from the rotation axis of the rotating connection part 100. Specifically, the first extrusion blade body section 320 is inclined in a direction away from the rotation axis of the rotating connection part 100. For details, please refer to the description above, which will not be repeated here.

[0129] In addition, in this embodiment, besides setting the first extrusion blade body section 320 to be inclined from top to bottom along the lower right, the second extrusion blade body section 330 can also be set to be inclined from top to bottom along the lower right, that is, the entire extrusion blade body 300 is inclined.

[0130] Alternatively, it can be in the direction from the top to the bottom of the dough scraper (see...). Figure 5 (as shown in the z direction), the second extrusion blade body section 330 extends vertically, while only the first extrusion blade body section 320 is inclined to the lower right.

[0131] By setting the second extrusion blade body section 330 to extend vertically, it is convenient to extrude the smaller dough 500 through the second extrusion blade body section 330, which is more conducive to extruding the smaller dough 500 into a larger dough 500 in the future. The larger dough 500 is then extruded into a complete large dough 500 by the first extrusion blade body section 320, which is conducive to the shaping of the complete large dough 500.

[0132] Reference Figure 5 As shown, along Figure 5 In the z-direction shown, the height dimension H1 of the first extrusion blade body section 320 is between 10mm and 80mm. By reasonably setting the height dimension of the first extrusion blade body section 320, it is advantageous to extrude larger dough balls 500. In addition, the height dimension H2 of the second extrusion blade body section 330 is between 5mm and 30mm. By reasonably setting the height dimension of the second extrusion blade body section 330, it is advantageous to extrude smaller dough balls 500.

[0133] In this embodiment, by reasonably setting the height dimensions of the first extrusion blade body section 320 and the second extrusion blade body section 330, it is beneficial for the first extrusion blade body section 320 to extrude the larger dough 500, while the second extrusion blade body section 330 extrudes the smaller dough 500, thereby subsequently extruding and shaping the complete large dough 500.

[0134] For example, the height of the first extrusion blade body section 320 can be 10mm, 50mm, or 80mm. The height of the second extrusion blade body section 330 can be 5mm, 15mm, or 30mm. When it is necessary to better extrude the small dough ball 500 into a larger dough ball 500, the height of the second extrusion blade body section 330 can be set to be larger; similarly, when it is necessary to better extrude the larger dough ball 500 into a complete large dough ball 500, the height of the first extrusion blade body section 320 can be set to be larger. The specific heights of the first extrusion blade body section 320 and the second extrusion blade body section 330 can be set according to actual needs.

[0135] Reference Figure 5 As shown, the right end face of the second extrusion blade body section 330 is set to not contact the inner wall of the container 400, that is, there is a certain gap D1 between the right end face of the second extrusion blade body section 330 and the inner wall of the container 400. The gap D1 is between 1mm and 30mm. By reasonably setting the gap range between the right end face of the second extrusion blade body section 330 and the inner wall of the container 400, an extrusion cavity that can accommodate a dough ball 500 of an appropriate size is formed between the right end face of the second extrusion blade body section 330 and the inner wall of the container 400, and then the dough ball 500 is extruded into a ball through the extrusion cavity.

[0136] In other words, when the size of the small dough ball 500 after mixing and extrusion is small, the gap between the right end face of the second extrusion blade body section 330 and the inner wall of the container 400 can be set to be small, for example, 2mm-10mm; when the size of the small dough ball 500 after mixing and extrusion is moderate, the gap between the right end face of the second extrusion blade body section 330 and the inner wall of the container 400 can be set to be moderate, for example, 10mm-20mm; when the size of the small dough ball 500 after mixing and extrusion is large, the gap between the right end face of the second extrusion blade body section 330 and the inner wall of the container 400 can be set to be large, for example, 20mm-30mm.

[0137] For example, the gap D1 between the left end face of the second extrusion blade body section 330 and the inner wall of the container 400 can be 2mm, 15mm or 30mm.

[0138] Reference Figures 5 to 8 As shown, along the direction of rotation of the dough scraper (refer to...) Figure 2 As shown by arrow s1, the extrusion blade body 300 can rotate at an angle relative to the rotating connection part 100, so that there is a certain angle between the extrusion working surface 310 and the rotation axis of the rotating connection part 100, thereby gradually reducing the distance between the extrusion working surface 310 and the rotation axis, which is beneficial for the extrusion blade body 300 to extrude the dough 500 during rotation.

[0139] Reference Figure 6 As shown, along the direction of rotation (refer to...) Figure 2 As indicated by the middle arrow s1, the mixing working surface 210 of the mixing blade body 200 is the side that contacts and mixes the flour. Therefore, the side of the extrusion blade body 300 facing the mixing working surface 210 can be designated as the rear side of the extrusion blade body 300, while the side of the extrusion blade body 300 away from its rear side can be designated as the front side of the extrusion blade body 300. The distance T1 between the front and rear sides of the extrusion blade body 300 is between 5mm and 30mm. In this embodiment, by reasonably setting the distance between the side of the extrusion blade body 300 facing the mixing working surface 210 and the side away from the mixing working surface 210, the extrusion blade body 300 has sufficient thickness, thereby possessing good strength and fatigue resistance.

[0140] For example, the distance T1 between the front side and the back side of the extrusion blade body 300 is 5mm, or 15mm, or 30mm. Specifically, the distance between the front side and the back side of the extrusion blade body 300 can be set according to actual needs, and this embodiment does not impose a specific limitation on it.

[0141] Reference Figure 5 As shown, in the direction from the top to the bottom of the dough scraper (refer to...) Figure 5 As shown in the z-direction, the bottom of the extrusion blade body 300 does not contact the bottom wall of the container 400; that is, a certain gap is reserved between the extrusion blade body 300 and the bottom wall of the container 400, specifically the gap D2, which ranges from 1mm to 30mm. In other words, in this embodiment, by reasonably setting the gap between the bottom of the extrusion blade body 300 and the bottom wall of the container 400, not only can the extrusion blade body 300 extrude smaller dough pieces 500, but the rotation of the extrusion blade body 300 by the container 400 can also be avoided.

[0142] For example, the gap D2 can be 1mm, 10mm, or 30mm. The specific value is set according to actual needs, and this embodiment does not impose any specific limitations on it.

[0143] In specific implementation, refer to Figure 5 and 7As shown, the distance between the upper end face of the extrusion working surface 310 and the inner wall of the container 400 is greater than the distance between the lower end face of the extrusion working surface 310 and the inner wall of the container 400, so that an extrusion cavity that can accommodate a larger dough ball 500 can be formed between the extrusion working surface 310 and the inner wall of the container 400, thereby allowing the larger dough ball 500 to be extruded to form a complete large dough ball 500.

[0144] In practice, the distance between the right end face of the extrusion blade body 300 and the inner wall of the container 400 can be set to gradually decrease or gradually decrease and then remain unchanged along the direction from the top to the bottom of the extrusion blade body 300.

[0145] Reference Figure 1 , Figure 3 , Figure 9 and Figure 10 As shown, along the direction from the top to the bottom of the dough scraper (refer to...) Figure 1 In the z-direction shown, at least part of the mixing blade body 200 is tilted to the lower left, so that the mixing blade body 200 can fully agitate the flour at the bottom of the container 400, thereby mixing the flour with water to form clumps or small dough balls 500.

[0146] In a specific implementation, the stirring blade body 200 can be tilted as a whole along the rotation axis away from the rotating connection part 100, or it can be tilted only partially along the rotation axis away from the rotating connection part 100.

[0147] In a specific implementation, the stirring blade body 200 includes a first stirring blade body segment 220 at the top and a second stirring blade body segment 230 connected to the bottom of the first stirring blade body segment 220, that is, the second stirring blade body segment 230 is located below the first stirring blade body segment 220. The first stirring blade body segment 220 and the second stirring blade body segment 230 can be integrally formed, that is, the stirring blade body 200 is essentially a complete whole, so that the stirring blade body 200 has sufficient structural strength.

[0148] In practice, the direction is from the top to the bottom of the dough-knife (refer to...). Figure 1 In the z-direction shown, only the first stirring blade body section 220 can be set to be tilted away from the rotation axis, so that the first stirring blade body section 220 can effectively stir the flour in the container 400, thereby mixing the flour and water.

[0149] In other words, the first stirring blade body 200 is inclined in a direction away from the rotation axis of the rotating connection portion 100, while the second stirring blade body 200 can also be configured to be inclined, extend vertically, or extend horizontally in a direction away from the rotation axis of the rotating connection portion 100.

[0150] In this embodiment, the second stirring blade body section 230 is along the horizontal direction (refer to...). Figure 1 Extending in the x direction (as shown), the second mixing blade body section 230 can fully mix the flour at the bottom of the container 400.

[0151] Additionally, along the direction from one end of the stirring blade body 200 near the rotating connection portion 100 to the end away from the rotating connection portion 100, i.e., referring to... Figure 1 As shown in the drawing orientation, the thickness of the stirring blade body 200 along the left-to-right direction can be set to be the same, or the thickness of the first stirring blade body segment 220 can be set to be greater than the thickness of the second stirring blade body segment 230, or the thickness of the first stirring blade body segment 220 can be set to be less than the thickness of the second stirring blade body segment 230.

[0152] Reference Figure 9 As shown, the second stirring blade body 200 does not contact the bottom wall of the container 400; that is, there is a preset gap D4 between the second stirring blade body 200 and the bottom wall of the container 400, with the preset gap D4 ranging from 1mm to 30mm. In this embodiment, by reasonably setting the preset gap between the second stirring blade body section 230 and the bottom wall of the container 400, the second stirring blade body section 230 can effectively stir the flour at the bottom of the container 400, allowing the flour and water to mix thoroughly, which is beneficial for subsequent extrusion into dough.

[0153] For example, the preset gap D4 can be 1mm, 15mm or 30mm.

[0154] Reference Figure 9 As shown, the gap D3 between the left end face of the second mixing blade body section 230 and the inner wall of the container 400 ranges from 2mm to 30mm. By reasonably setting the gap between the left end face of the second mixing blade body section 230 and the inner wall of the container 400, the second mixing blade body section 230 can be fully mixed with the flour, and the container 400 can be ensured not to interfere with the rotation of the second mixing blade body section 230.

[0155] For example, the gap D3 between the left end face of the second stirring blade body section 230 and the inner wall of the container 400 can be 2mm, 15mm or 30mm.

[0156] Reference Figure 9 As shown, along the direction from the right end to the left end of the second stirring blade body section 230, the height of the second stirring blade body section 230 gradually decreases in the vertical direction, which facilitates the injection molding of the second stirring blade body section 230.

[0157] Reference Figure 9 As shown, the height T2 of the second stirring blade body section 230 in the vertical direction ranges from 3mm to 20mm. By reasonably setting the height dimension of the second stirring blade body section 230 in the vertical direction, the second stirring blade body section 230 has sufficient height to meet the strength requirements.

[0158] For example, the height T2 of the second stirring blade body section 230 in the vertical direction can be 3mm, 10mm, or 20mm.

[0159] Reference Figure 10 As shown, the distance T3 between the front side and the back side of the second stirring blade body section 230 ranges from 5mm to 30mm. By reasonably setting the distance between the front side and the back side of the second stirring blade body section 230, the second stirring blade body section 230 has sufficient thickness to meet the strength requirements.

[0160] For example, the distance T3 between the front side and the back side of the second stirring blade body section 230 is 5mm, or 15mm, or 30mm.

[0161] Reference Figure 1 and Figure 3 As shown, the top of the rotating connector 100 protrudes upward to form an arc-shaped protrusion or a pointed protrusion, thereby preventing flour from accumulating on the top of the rotating connector 100 when flour is poured into the container 400.

[0162] In practice, the top of the rotating connector 100 can be hemispherical or conical, thus preventing flour from accumulating on the top of the rotating connector 100. More specifically, the top of the rotating connector 100 can be a smooth surface, further preventing flour or water from accumulating on the top of the rotating connector 100.

[0163] In addition, the rotating connection part 100 can be injection molded or integrally cast.

[0164] Example 2

[0165] Reference Figures 1 to 13 As shown, this embodiment provides a mixing device, including a container 400, a drive assembly 610, and a dough-kneading blade disposed within the container 400. Specifically, the container 400 can be a dough-kneading bucket or a mixing bucket. The structure and corresponding effects of the dough-kneading blade are the same as those described in Embodiment 1.

[0166] In simple terms, the mixing blade body 200 and the extrusion blade body 300 of the dough kneading knife are distributed at intervals along the circumference of the rotating connection portion 100. This allows the mixing blade body 200 and the extrusion blade body 300 to be distributed at different positions in the circumference of the rotating connection portion 100. Thus, when the mixing blade body 200 is mixing water and flour and thus bearing a load, and the extrusion blade body 300 is extruding dough and thus bearing a load, the load borne by the mixing blade body 200 and the load borne by the extrusion blade body 300 can be distributed at different positions in the circumference of the rotating connection portion 100, so as to avoid the load being concentrated on the same side of the rotating connection portion 100, which would easily cause the dough kneading knife to fatigue and be damaged.

[0167] Since the mixing blade body 200 and the extrusion blade body 300 are used for mixing and extrusion respectively, the loads for mixing and extruding the flour into a dough are borne by the mixing blade body 200 and the extrusion blade body 300 respectively. Therefore, compared to the mixing and extrusion loads being concentrated on the same side of a dough knives, different parts of the dough knives in this embodiment are used to bear the corresponding loads respectively, thus making the load borne by each part relatively small. That is to say, the extrusion working surface 310 and the mixing working surface 210 of the dough knives of this mixing device are located on different sides of the dough knives, so that the mixing and extrusion of the flour can be achieved through different sides. This avoids the problem of concentrated mixing and extrusion loads on the same side of the dough knives, which can lead to load concentration and fatigue damage. In some embodiments, the drive assembly 610 includes a drive motor 611 and a gearbox 612. One end of the gearbox 612 is connected to the output shaft of the drive motor 611, and the other end of the gearbox 612 is connected to the rotating connection part 100. The gearbox 612 is used to drive the rotating connection part 100 to rotate under the drive of the drive motor 611, so as to realize the stirring and extrusion operation.

[0168] In specific implementation, refer to Figure 5 As shown, the extrusion blade body 300 is divided into two sections from top to bottom: the upper section is the first extrusion blade body section 320, and the lower section is the second extrusion blade body section 330. The second extrusion blade body section 330 and the first extrusion blade body section 320 can be integrally formed to ensure overall structural strength. Alternatively, the first extrusion blade body section 320 and the second extrusion blade body section 330 can be formed separately and then welded or bonded together.

[0169] In some embodiments, refer to Figure 5As shown, the right end face of the second extrusion blade body section 330 is set to not contact the inner wall of the container 400, that is, there is a certain gap D1 between the right end face of the second extrusion blade body section 330 and the inner wall of the container 400. The gap D1 is between 1mm and 30mm. By reasonably setting the gap range between the right end face of the second extrusion blade body section 330 and the inner wall of the container 400, an extrusion cavity that can accommodate a dough of an appropriate size is formed between the right end face of the second extrusion blade body section 330 and the inner wall of the container 400, and the dough is then extruded into a ball through the extrusion cavity.

[0170] In other words, when the size of the dough after mixing and extrusion is small, the gap between the right end face of the second extrusion blade body section 330 and the inner wall of the container 400 can be set to be small, such as 2mm-10mm; when the size of the dough after mixing and extrusion is moderate, the gap between the right end face of the second extrusion blade body section 330 and the inner wall of the container 400 can be set to be moderate, such as 10mm-20mm; when the size of the dough after mixing and extrusion is large, the gap between the right end face of the second extrusion blade body section 330 and the inner wall of the container 400 can be set to be large, such as 20mm-30mm.

[0171] For example, the gap D1 between the left end face of the second extrusion blade body section 330 and the inner wall of the container 400 can be 2mm, 15mm or 30mm.

[0172] Reference Figures 5 to 8 As shown, along the direction of rotation of the dough scraper (refer to...) Figure 2 As shown by arrow s1, the extrusion blade body 300 can rotate at an angle relative to the rotating connection part 100, so that there is a certain angle between the extrusion working surface 310 and the rotation axis of the rotating connection part 100, thereby gradually reducing the distance between the extrusion working surface 310 and the rotation axis, which is beneficial for the extrusion blade body 300 to extrude dough during rotation.

[0173] For example, in this embodiment, the rotation direction can be clockwise. In the clockwise direction, since the distance between the extrusion working surface 310 and the rotation axis gradually decreases, an extrusion cavity with a gradually increasing opening is formed between the extrusion working surface 310 and the inner wall of the container 400, so that the dough 500 can enter the extrusion cavity and be extruded to form a large dough 500.

[0174] Specifically, a gap can be formed between the right end face of the first extrusion blade body section 320 and the inner wall of the container 400, as shown in the figure. Figure 5 The included angle ∠a is shown. Specifically, ∠a can be 5°, 30°, or 60°.

[0175] And / or, a space can be formed between the right end face of the second extrusion blade body section 330 and the inner wall of the container 400, such as Figure 6 The angle ∠b shown ranges from 5° to 60°. For example, ∠b can be 5°, 30°, or 60°.

[0176] In specific implementation, refer to Figure 5 and 7 As shown, in the direction from the top of the extrusion blade body 300 to the bottom of the extrusion blade body 300 (refer to...) Figure 1 (As shown in the z direction), the distance between the upper end face of the extrusion working surface 310 and the inner wall of the container 400 is greater than the distance between the lower end face of the extrusion working surface 310 and the inner wall of the container 400, so that an extrusion cavity that can accommodate a larger dough can be formed between the extrusion working surface 310 and the inner wall of the container 400, thereby allowing the larger dough to be extruded to form a complete large dough 500.

[0177] In a specific implementation, the stirring blade body 200 includes a first stirring blade body segment 220 at the top and a second stirring blade body segment 230 connected to the bottom of the first stirring blade body segment 220, that is, the second stirring blade body segment 230 is located below the first stirring blade body segment 220. The first stirring blade body segment 220 and the second stirring blade body segment 230 can be integrally formed, that is, the stirring blade body 200 is essentially a complete whole, so that the stirring blade body 200 has sufficient structural strength.

[0178] In practice, the direction is from the top to the bottom of the dough-knife (refer to...). Figure 1 In the z-direction shown, only the first stirring blade body section 220 can be set to be tilted away from the rotation axis, so that the first stirring blade body section 220 can effectively stir the flour in the container 400, thereby mixing the flour and water.

[0179] In other words, the first stirring blade body 200 is inclined in a direction away from the rotation axis of the rotating connection portion 100, while the second stirring blade body 200 can also be configured to be inclined, extend vertically, or extend horizontally in a direction away from the rotation axis of the rotating connection portion 100.

[0180] In this embodiment, the second stirring blade body section 230 is along the horizontal direction (refer to...). Figure 1 Extending in the x direction (as shown), the second mixing blade body section 230 can fully mix the flour at the bottom of the container 400.

[0181] Additionally, along the direction from one end of the stirring blade body 200 near the rotating connection portion 100 to the end away from the rotating connection portion 100, i.e., referring to... Figure 1As shown in the drawing orientation, the thickness of the stirring blade body 200 along the left-to-right direction can be set to be the same, or the thickness of the first stirring blade body segment 220 can be set to be greater than the thickness of the second stirring blade body segment 230, or the thickness of the first stirring blade body segment 220 can be set to be less than the thickness of the second stirring blade body segment 230.

[0182] Reference Figure 9 As shown, the second stirring blade body 200 does not contact the bottom wall of the container 400; that is, there is a preset gap D4 between the second stirring blade body 200 and the bottom wall of the container 400, with the preset gap D4 ranging from 1mm to 30mm. In this embodiment, by reasonably setting the preset gap between the second stirring blade body section 230 and the bottom wall of the container 400, the second stirring blade body section 230 can effectively stir the flour at the bottom of the container 400, allowing the water and flour to mix thoroughly, which is beneficial for subsequent extrusion into dough.

[0183] For example, the preset gap D4 can be 1mm, 15mm or 30mm.

[0184] Reference Figure 9 As shown, the gap D3 between the left end face of the second mixing blade body section 230 and the inner wall of the container 400 ranges from 2mm to 30mm. By reasonably setting the gap between the left end face of the second mixing blade body section 230 and the inner wall of the container 400, the second mixing blade body section 230 can be fully mixed with the flour, and the container 400 can be ensured not to interfere with the rotation of the second mixing blade body section 230.

[0185] For example, the gap D3 between the left end face of the second stirring blade body section 230 and the inner wall of the container 400 can be 2mm, 15mm or 30mm.

[0186] The specific method of using this mixing device for dough mixing is as follows: First, flour is added to container 400, then water is added in proportion. After adding water, the drive motor 611 of the drive assembly 610 starts, driving the dough mixing blade to rotate in the direction of rotation (e.g., clockwise) through the gearbox 612. Under the action of the mixing blade body 200 and the extrusion blade body 300, the water and flour begin to mix. The mixing blade body 200 is located at the bottom of container 400 and can turn over the flour at the bottom of container 400, facilitating flour mixing. The extrusion blade body 300 is higher and can turn over the water and flour on the surface, allowing the water and flour to be initially mixed.

[0187] After the water and flour are initially mixed, they gradually form dough flakes and small dough balls during stirring. During the folding process, smaller particles sink while larger particles rise. The smaller dough balls at the bottom are compressed by the lower part of the extrusion blade 300, while the larger dough balls are compressed by the upper part of the extrusion blade 300. The flour and dough flakes are folded by the mixing blade 200, and during this folding process, the flour at the bottom gradually combines completely into dough flakes. The dough flakes and small dough balls at the bottom are gradually combined into larger dough balls under the compression of the mixing section. As the dough balls grow larger, they are compressed by the upper part of the extrusion blade 300, and with the action of the extrusion blade 300, a complete large dough ball 500 is gradually formed.

[0188] The specific structure and implementation principle of the dough-knife in this embodiment are the same as those of the dough-knife provided in Embodiment 1, and can bring the same or similar technical effects. They will not be described in detail here. For details, please refer to the description in Embodiment 1.

[0189] In addition, the mixing device in this embodiment can be used in a dough mixer to make dough. Alternatively, the mixing device can also be used in a noodle machine to extrude the dough or clumps formed after kneading to form noodle products, such as noodles, noodle sheets, or pasta.

[0190] Example 3

[0191] Reference Figures 1 to 13 As shown, this embodiment also provides a noodle machine, including a base 800 and the aforementioned mixing device, which is mounted on the base 800. This noodle machine can be used to make various noodle products, such as noodles, dough sheets, and pasta of various shapes and thicknesses; or, it can also be used to make dough.

[0192] Specifically, the mixing device of this noodle machine includes a dough-kneading blade, which comprises a rotating connecting part 100, a mixing blade body 200, and an extrusion blade body 300. The mixing blade body 200 and the extrusion blade body 300 are distributed at intervals along the circumference of the rotating connecting part 100, so that the mixing blade body 200 and the extrusion blade body 300 are distributed at different positions in the circumference of the rotating connecting part 100. This allows the load borne by the mixing blade body 200 when mixing water and flour and the load borne by the extrusion blade body 300 when extruding dough to bear load to be distributed at different positions in the circumference of the rotating connecting part 100. This avoids the load being concentrated on the same side of the rotating connecting part 100, which would cause the dough-kneading blade to easily fatigue and be damaged, and thus makes the noodle machine with this dough-kneading blade have a longer overall service life.

[0193] The specific working process of this noodle machine is as follows: First, an appropriate amount of flour and water are added to the container 400. Then, the drive assembly 610 drives the rotating connecting part 100 to rotate in the rotational direction. The rotating connecting part 100 then drives the mixing blade body 200 and the extrusion blade body 300 to rotate in the same direction (e.g., clockwise). Under the action of the mixing blade body 200 and the extrusion blade body 300, the water and flour begin to mix. The mixing blade body 200 is located at the bottom of the container 400 and can agitate the flour at the bottom of the container 400, facilitating mixing. The extrusion blade body 300 is higher and can agitate the water and flour on the surface, allowing the water and flour to mix initially.

[0194] After the water and flour are initially mixed, they gradually form dough flakes and small dough balls during stirring. During the folding process, smaller particles sink while larger particles rise. The smaller dough balls at the bottom are compressed by the lower part of the extrusion blade 300, while the larger dough balls are compressed by the upper part of the extrusion blade 300. The flour and dough flakes are folded by the mixing blade 200, and during this folding process, the flour at the bottom gradually combines completely into dough flakes. The dough flakes and small dough balls at the bottom are gradually combined into larger dough balls under the compression of the mixing section. As the dough balls grow larger, they are compressed by the upper part of the extrusion blade 300, and with the action of the extrusion blade 300, a complete large dough ball 500 is gradually formed.

[0195] The noodle machine in this embodiment includes a mixing device with the same structure and implementation principle as the mixing device provided in Embodiment 2, and can bring the same or similar technical effects. It will not be described in detail here, but you can refer to the description in Embodiment 2 for details.

[0196] Among them, reference Figure 13 As shown in the drawing orientation, the base 800 can be divided into left and right parts, namely, a first mounting part 815 and a second mounting part 816. The right half of the base 800 is designated as the first mounting part 815, and the left half as the second mounting part 816, with the second mounting part 816 being higher than the first mounting part 815. The top of the second mounting part 816 is higher than the top of the first mounting part 815, and the bottoms of the first mounting part 815 and the second mounting part 816 are flush. This allows the top surface of the first mounting part 815 and the side of the second mounting part 816 closest to the container 400 (i.e., the right side) to together form an L-shaped accommodating structure 817, which can be used to mount the container 400. It should be noted that the accommodating structure 817 may specifically include a cavity for accommodating the container 400, which is formed by the top surface of the first mounting part 815 and the side wall of the second mounting part 816 near the container 400 together.

[0197] In addition, the noodle machine may also be equipped with a water tank assembly 700, which is connected to the water supply of the container 400, thereby adding water to the container 400. Specifically, the water tank assembly 700 can be installed on the top of the machine base 800 for easy installation.

[0198] In a specific implementation, the top of the base 800 has a mounting cavity adapted to the water tank assembly 700. The water tank assembly 700 is installed in the mounting cavity and can be snapped or screwed onto the base 800, so that if either the water tank assembly 700 or the base 800 is damaged, they can be disassembled so that only the damaged one needs to be replaced. Furthermore, the water tank assembly 700 can specifically include a circular water tank or a square water tank; the specific shape and capacity of the water tank can be set according to actual needs, and this embodiment does not specifically limit this. Specifically, the water tank assembly 700 and the container 400 can be arranged sequentially along the length of the base 800, i.e., referring to... Figure 13 As shown, the water tank assembly 700 can be located on the left side of the container 400.

[0199] In specific implementation, the connection structure between the water tank assembly 700 and the mounting cavity is as follows: a first snap-fit ​​part can be provided on the bottom of the water tank assembly 700, and a second snap-fit ​​part can be provided on the mounting cavity at the position corresponding to the first snap-fit ​​part. Through the snap-fit ​​cooperation of the first snap-fit ​​part and the second snap-fit ​​part, the water tank assembly 700 is fixed in the mounting cavity, which can ensure that the water tank assembly 700 will not shake or fall off, and also makes it easy to disassemble the water tank assembly 700.

[0200] For example, in this embodiment, the first snap-fit ​​part can be a snap rib, and the second snap-fit ​​part can be a snap groove. Thus, when the water tank assembly 700 is installed from top to bottom, the snap rib at the bottom of the water tank assembly 700 is inserted into the snap groove in the mounting cavity, thereby achieving a detachable connection. Alternatively, the first snap-fit ​​part can be a snap groove, and the second snap-fit ​​part can be a snap rib. The snap groove at the bottom of the water tank assembly 700 engages the snap rib in the mounting cavity to achieve a detachable connection.

[0201] In addition, in this embodiment, in order to facilitate the installation of the water tank assembly 700 from top to bottom, when setting the retaining rib, the retaining rib can extend along the direction from the bottom to the top of the base 800, so that when the water tank assembly 700 is snapped on from top to bottom, the water tank assembly 700 directly cooperates with the retaining groove through the vertically extending retaining rib to achieve its fixed connection on the mounting cavity.

[0202] Of course, in other implementations, the retaining rod can also extend horizontally. In this case, the water tank assembly 700 can be tilted slightly first, and the retaining rod can be inserted into the slot before the water tank assembly 700 is installed in the mounting cavity.

[0203] In summary, the water tank assembly 700 of this embodiment can be installed vertically from top to bottom, which makes the installation, disassembly, and maintenance of the water tank assembly 700 more convenient. Of course, in other implementations, the water tank assembly 700 can also be installed on the base 800 from the side. The specific installation method of the water tank assembly 700 can be set according to actual needs, and this embodiment does not impose specific limitations on it.

[0204] In addition, the container 400 may specifically include a mixing cup 420 and a lid 410, with a dust cover 430 provided on the lid 410. Specifically, the lid 410 has a water inlet, allowing water from the water tank assembly 700 to enter the mixing cup 420 through the water inlet on the lid 410. To prevent dust contamination of the water inlet, a dust cover 430 can be provided around the lid 410 to shield the water inlet, thus preventing contamination and making the overall outer surface of the container 400 more aesthetically pleasing and smooth.

[0205] In a specific implementation, the lower end of the rotating connection part 100 of the dough-mixing knife is connected to the drive assembly 610 for transmission, while the upper end of the rotating connection part 100 can be as follows: Figure 1 The free end shown; or, as shown Figure 11 As shown, the upper end of the rotating connecting part 100 can also abut or engage with the cup lid 410. Specifically, it can engage with the cup lid 410, thereby restricting the upward movement of the dough-making knife. Specifically, a snap-fit ​​hole is provided on the bottom surface of the cup lid 410. The shape of the snap-fit ​​hole can be set to match the outer contour of the rotating connecting part 100, so that the upper end of the rotating connecting part 100 is engaged in the snap-fit ​​hole.

[0206] Furthermore, the noodle machine also includes a dough extrusion assembly 900. Specifically, the dough extrusion assembly 900 may include an extrusion cylinder 910 connected to the container 400, an extrusion screw 920 disposed within the extrusion cylinder 910, and a dough extrusion die 930. After the dough kneading knife kneads the flour into a dough flake or a small dough ball, the dough flake or small dough ball enters the extrusion cylinder 910 and is conveyed to the dough extrusion die 930 under the extrusion of the extrusion screw 920. After passing through the dough extrusion die 930, noodle products of any shape and thickness can be produced, thereby completing the preparation of noodle products.

[0207] The dough ejector head 930 can be specifically equipped with ejector sections for making different dough products. For example, the ejector section can be a round hole to make round noodles, and the diameter of the round hole can be selected according to the thickness of the noodles to be made. Alternatively, the ejector section can be a square hole to make flat noodles. Or, the ejector section can be oval to make noodles, etc. The specific shape and size of the ejector section can be selected according to the actual dough product to be made.

[0208] Furthermore, the extrusion die 930 can have multiple extrusion faces, which can be arranged in an array to extrude and form multiple dough products with the same or different face shapes in a single operation. That is, when the shapes and sizes of the multiple extrusion faces are identical, the dough products formed in a single extrusion will have identical face shapes; when the shapes and / or sizes of the multiple extrusion faces are not entirely identical, the dough products formed in a single extrusion will also not have entirely identical face shapes. In practical use, the shapes and sizes of the multiple extrusion faces on a single extrusion die 930 are generally the same.

[0209] In practice, the extrusion die 930 can be set on the bottom surface of the extrusion cylinder 910, so that the noodles and other noodle products extruded by the extrusion die 930 can slowly fall down the bottom surface of the extrusion cylinder 910.

[0210] In a specific implementation, the gearbox 612 includes a housing and a drive shaft and a bevel gear assembly disposed within the housing. The housing is connected to the base 800. The drive shaft is connected to the drive motor 611, and the bevel gear assembly is disposed on the drive shaft, so that when the drive motor 611 drives the drive shaft to rotate, it can drive the bevel gear assembly to rotate, thereby enabling the drive shaft and the bevel gear assembly to transmit forces in different directions.

[0211] In practice, the left end of the drive shaft is connected to the output shaft of the drive motor 611, the extrusion screw 920 is connected to the right end of the drive shaft, and the bevel gear assembly is located on the drive shaft and connected to the rotating connection part 100. This allows the drive shaft to directly or indirectly provide driving forces in different directions to the extrusion screw 920 and the rotating connection part 100, so that the dough kneading knife can stir the flour and water in the container 400 to form dough flakes. The extrusion screw 920 can then drive the stirred dough flakes so that they are extruded and shaped by the extrusion die head 930.

[0212] More specifically, the bevel gear assembly includes two bevel gears, namely a first bevel gear and a second bevel gear. The first bevel gear is mounted on the drive shaft, the second bevel gear meshes with the first bevel gear, and the second bevel gear is connected to the rotating connection part 100.

[0213] The specific driving process is as follows: When kneading dough is required, the drive motor 611 can rotate in the forward direction, thereby driving the transmission shaft to rotate and causing the first bevel gear to rotate. This causes the second bevel gear, which meshes with the first bevel gear, to rotate. The rotation of the second bevel gear drives the rotating connection part 100 to rotate. At this time, the mixing blade body 200 and the extrusion blade body 300 rotate to knead the dough. When processing dough products is required, the drive motor 611 can rotate in the reverse direction, thereby driving the transmission shaft to rotate and causing the extrusion screw 920 connected to the transmission shaft to rotate. This extrudes the dough and forms it from the dough exiting the die head 930.

[0214] In addition, a bottom cover 810 is provided at the bottom of the base 800. In a specific implementation, the noodle machine may also include a water pump assembly 830. The bottom cover 810 and the base 800 together form a closed chamber for housing the water pump assembly 830, etc.

[0215] During dough making, the water pump assembly 830 connects the container 400 and the water tank assembly 700 to pump water from the water tank assembly 700 to the container 400. Then, an appropriate amount of flour can be weighed and added to the container. The drive assembly 610 then drives the dough kneading blade in the container 400 to rotate for kneading or mixing the dough. When the kneading or mixing is completed and it is necessary to make noodles or other dough products, the drive assembly 610 can drive the extrusion screw 920 in the extrusion cylinder 910 to rotate, so as to transport the dough flakes or dough to the dough extrusion die head 930 for extrusion and shaping before sending it out, thus completing one round of dough making.

[0216] Additionally, an electronic scale 820 can be configured outside the noodle machine in this embodiment for weighing flour, allowing for precise mixing of flour and water to produce noodle products (such as noodles, noodle sheets, etc.). Specifically, the electronic scale 820 can be a Bluetooth electronic scale. The specific model and size of the electronic scale 820 can be selected according to actual needs.

[0217] The specific noodle preparation process is as follows: The electronic scale 820 is first connected to the noodle machine via Bluetooth or a signal cable. After the electronic scale 820 weighs the flour, press the menu button on the operation display panel 620 of the noodle machine to select the corresponding noodle button, then pour the weighed flour into the mixing cup 420 of the container, and then close the cup lid 410. Select the corresponding instruction, start the program, and the noodle machine starts running and executing the corresponding instructions. The water pump assembly 830 transfers water from the water tank assembly 700 into the mixing cup 420. The driving assembly 610 drives the kneading blade in the mixing cup 420 to rotate, and the kneading blade mixes the flour and water to form dough flakes. Then, the driving assembly 610 drives the extrusion screw 920 of the extrusion assembly 900 to transport the dough flakes to the extrusion die head 930 of the extrusion assembly 900 for extrusion and shaping, thus completing one noodle making cycle.

[0218] The specific dough-making process is as follows: The electronic scale 820 and the noodle machine are first connected via Bluetooth or a signal cable. After the electronic scale 820 weighs the flour, press the menu button on the operation display panel 620 of the noodle machine to select the corresponding dough button, then pour the weighed flour into the mixing cup 420, and then close the lid 410. Select the corresponding instruction, start the program, and the noodle machine starts running and executing the corresponding instructions. The water pump 830 transfers water from the water tank 700 into the mixing cup 420. The drive component 610 drives the kneading blades in the mixing cup 420 to rotate, and the kneading blades mix the flour and water to form small dough balls. Then, the small dough balls are combined under the extrusion action of the extrusion blade body 300 to form a complete large dough ball.

[0219] In a practical implementation, the drive assembly 610 can be placed inside the base 800 and below the water tank assembly 700. Specifically, the drive motor 611 of the drive assembly 610 can provide two forces: one in the vertical direction and one in the balanced direction. The vertical force is applied to the dough-mixing blade to mix the flour and water (or other liquids) into dough flakes; the balanced force is applied to the extrusion screw 920 to extrude and shape the dough.

[0220] In practice, the water pump assembly 830 is located within the base 800, above the drive assembly 610, and to one side of the water tank assembly 700. This proximity to the water tank assembly 700 results in a more compact internal structure for the entire noodle machine, reducing water circuit errors. During operation, pressing a button on the operation display panel assembly 620 automatically adds water. The water pump in the water pump assembly 830 then starts, drawing water from the water tank assembly 700 through its water pipe into the pump, which then flows out of the base 800 and into the mixing cup 420. Specifically, the buttons can include a noodle button and a dough button. Pressing the noodle button allows for the production of noodles and other noodle products, while pressing the dough button allows for the production of dough.

[0221] Additionally, refer to Figure 13 As shown, the noodle machine in this embodiment may also be equipped with an air-guiding and drainage system 840, which is placed below the container 400 and close to the noodle outlet on the machine base 800. The air-guiding and drainage system 840 is used to draw air from the bottom of the machine base 800 through the fan 841 and discharge it through the air outlet 811 of the machine base 800. The air outlet 811 corresponds to the noodle outlet, thereby drying the extruded noodles and reducing food sticking.

[0222] In its specific implementation, the air guiding and drainage system 840 includes a drawer assembly 842, a drawer bracket 843, a fan 841, and a fan cover 844. The drawer assembly 842 is installed inside the drawer bracket 843. The fan 841 is used to transmit air entering from the bottom of the bottom cover 810 to the air outlet 811 to dry the noodles extruded from the noodle outlet. The fan cover 844 is used to cover the outside of the fan 841, thus protecting it. Furthermore, the fan cover 844 has an opening corresponding to the air outlet of the fan 841, through which the air blown by the fan 841 is blown out through the air outlet 811 on the base 800. Additionally, the drawer bracket 843 can be connected to the base 800 via a snap-fit ​​connection, or it can be connected to the base 800 via screws or other fasteners.

[0223] In practice, the air outlet 811 can be located on the right side of the base 800, and the extrusion cylinder 910 is located at the bottom of the container 400 and extends in the direction of the extrusion cylinder 910. This allows the air blown out from the air outlet 811 to blow onto the dough product extruded from the extrusion die 930 at the bottom of the right end face of the extrusion cylinder 910, thereby drying the dough product and preventing it from sticking together.

[0224] For example, the shape of the air outlet 811 can be a square air outlet, or it can be a round or diamond-shaped air outlet. The specific shape and size of the air outlet 811 can be selected according to actual needs. This embodiment does not make specific limitations in this regard.

[0225] In addition, after using the electronic scale 820, it can be stored in the drawer assembly 842 to prevent it from being easily lost.

[0226] In addition, refer to Figure 13 As shown, a heating film 812 can also be installed at the bottom of the container 400 to enable the dough proofing function.

[0227] In addition, a decorative element 813 is provided on the top of the base 800. By covering the top of the base 800 with the decorative element 813, and referring to... Figure 13 As shown in the drawing, the left and right ends of the decorative piece 813 extend downwards to fit against the opposite sides of the base 800, thus decorating the outer surface of the base 800 and improving the appearance of the noodle machine. Furthermore, the two ends of the decorative piece 813 are detachably connected to the corresponding positions on the sides of the base 800 to ensure easy removal and replacement of the decorative piece 813 to meet different user needs.

[0228] In addition, a side decorative panel 814 is provided, and the side decorative panel 814 overlaps with the portion of the decorative piece 813 that extends to the side of the base 800, thereby further enhancing the appearance of the noodle machine.

[0229] In practice, the side decorative panel 814 is a straight plate or a specially shaped part with ribs around its perimeter. The bottom surface of the ribs is a flat surface, and these ribs serve to strengthen the side decorative panel 814. Furthermore, the ribs on the side wall of the side decorative panel 814 and the corresponding grooves on the outer side of the base 800 form a guide rail structure. The side decorative panel 814 can slide into the side of the base 800 from the bottom. The grooves in the base 800 restrain the side decorative panel 814, preventing it from slipping out. Finally, the bottom cover 810 is placed on top, and the bottom cover 810 is fixed to the base 800 with screws, pressing the side decorative panel 814 onto the base 800 to prevent it from moving.

[0230] Furthermore, the operation display panel assembly can be equipped with control buttons for starting the drive assembly 610, thereby driving the dough-mixing blade and / or the extrusion screw 920 to perform corresponding operations. Specifically, the operation display panel assembly 620 may include a control board and a display screen, which are located at corresponding positions on the machine base 800. The control board is equipped with control buttons; pressing the corresponding position on the display screen triggers different function control buttons, thereby causing the noodle machine to perform different operations. The specific structure and control process of the operation display panel assembly 620 can be found in existing descriptions, and this embodiment does not impose specific limitations on them.

[0231] In a specific implementation, in order to facilitate user operation of the operation display panel assembly 620, the operation display panel assembly 620 in this embodiment is not vertically arranged as in the prior art, but is inclined and is inclinedly arranged on the side of the base 800.

[0232] Example 4

[0233] Reference Figure 14 As shown, this embodiment provides a method for preparing pasta using a noodle machine. This method can be performed by part or all of the noodle machine described in the above embodiment to prepare different pasta.

[0234] Combining 1 to Figure 14 As shown, the method for preparing pasta using a noodle machine will be described below through specific embodiments. The method specifically includes:

[0235] S101: Add water and flour in a preset mass ratio to the container. In this step, an electronic scale can be used to weigh the flour and measure the water, so that the flour and water can be accurately mixed to prepare dough or dough products (such as noodles, dough sheets, etc.).

[0236] In practice: The electronic scale can connect to the noodle machine via Bluetooth or a signal cable. After the scale has weighed the flour, press the menu button on the noodle machine to select the corresponding control command. Then, pour the weighed flour into the mixing cup of the container and close the lid. Select the appropriate command to start the program, and the noodle machine will begin executing the corresponding instructions.

[0237] When kneading dough, the preset mass ratio of water to flour can range from 35% to 60%. For example, the preset mass ratio of water to flour added to the container can be 35%, 45%, or 60%.

[0238] When making dough products, the preset mass ratio of water to flour can be in the range of 30%-40%. For example, the preset mass ratio of water to flour added to the container can be 30%, or 35%, or 40%.

[0239] Generally, the amount of water and flour needed to prepare noodle products is relatively small, so that the dough flakes formed by mixing water and flour can be easily extruded and shaped later. For example, the preset mass ratio of water and flour added to the container can be 30%, 35%, or 40%.

[0240] S102: Drive the dough-mixing blade to rotate in a first rotation direction, so that water and flour are mixed under the action of the mixing blade body and the extrusion blade body to form at least a first dough; and extrusion blade body extrudes the multiple first doughs formed by the mixture to form a second dough, wherein the second dough is larger than the first dough; or,

[0241] The dough knives are driven to rotate in a first rotation direction so that water and flour are mixed under the action of the mixing blade body and the extrusion blade body and at least form dough flakes; the extrusion screw in the extrusion cylinder connected to the container is driven to rotate in a second rotation direction so that the dough flakes entering the extrusion cylinder are moved to the extrusion die head by the extrusion screw and extruded by the extrusion die head to form a dough product; wherein, the first rotation direction is opposite to the second rotation direction.

[0242] In other words, the method for preparing pasta in this embodiment can not only knead the dough to form a complete second dough (i.e., the final large dough), but also make pasta products to produce pasta products of the required shape or size (pastry products can be noodles of different thicknesses, sesame balls, noodle sheets, etc.).

[0243] When it is necessary to knead dough, the specific operation process can be as follows: First, add water and flour to the container in a preset mass ratio. The preset mass ratio of water and flour can be in the range of 35%-60%. The specific preset mass ratio of water and flour added to the container can be selected according to actual needs.

[0244] Then, the driving blade can rotate clockwise. At this time, the mixing blade and the extrusion blade body play a role in mixing the water and flour in the container, so that the flour and water are mixed to form the first dough. The first dough is a small dough with a relatively small overall size.

[0245] Finally, as the drive motor rotates clockwise and drives the dough-mixing blade to rotate clockwise, the extrusion blade body extrudes the several small dough balls formed by the mixing, thereby extruding and combining the several small dough balls to form a complete large dough ball, namely the second dough ball.

[0246] When making flour products, the specific operation process is as follows: First, add water and flour in a preset mass ratio into the container. The preset mass ratio of water and flour can be in the range of 30%-40%, and the specific preset mass ratio of water and flour added into the container can be selected according to actual needs.

[0247] Then, the driving blade can rotate clockwise. At this time, the mixing blade and the extrusion blade body play a role in mixing the water and flour in the container, so that the flour and water are mixed to form small dough flakes.

[0248] Finally, the dough flakes are conveyed into the extrusion cylinder, and the drive motor rotates counterclockwise, which in turn drives the extrusion screw to rotate, so as to convey the dough flakes in the extrusion cylinder to the dough die head for extrusion molding, thereby producing the desired dough products.

[0249] In step S102, the specific steps for making the second dough may include:

[0250] S1021: Drive the dough-mixing blade to rotate in the first rotation direction so that water and flour are mixed under the action of the mixing blade body and the extrusion blade body and at least form dough flakes and a first dough. That is, when the mixing blade body and the extrusion blade body mix water and flour, part of the flour in the container is stirred to form the first dough, while part is not stirred and part is stirred to form small dough flakes.

[0251] S1022: The unmixed flour and small clumps formed in the container are further mixed and stirred to form several first doughs. The sizes of these first doughs are not exactly the same.

[0252] For ease of description of the extrusion operation, in this embodiment, the larger portion of the first dough can be designated as the second sub-dough, while the smaller portion of the first dough can be designated as the first sub-dough. However, in actual operation, the dimensions of each of the several first doughs may not be exactly the same. Therefore, it should not be understood that the first dough includes only two different sizes of dough; that is, the first dough is not limited to including the first sub-dough and the second sub-dough.

[0253] S1023: After water and flour are mixed to form a first dough, the part of the extrusion blade body near the bottom of the container extrudes the first sub-dough, and the part of the extrusion blade body away from the bottom of the container extrudes the second sub-dough, so that the first sub-dough and the second sub-dough are extruded to form the second dough.

[0254] In specific implementation, based on the structure of the extrusion blade body in the above embodiment 1, the distance between the part of the extrusion blade body near the bottom of the container and the inner wall of the container is small, so it can extrude a smaller size of the first dough; while the distance between the part of the extrusion blade body near the top of the container and the inside of the container gradually increases from bottom to top, so it can extrude a larger size of the first dough, and finally extrude several first doughs of different sizes into a complete larger size of the second dough.

[0255] In other words, the mixing blade is located at the bottom of the container, allowing it to agitate the flour at the bottom and facilitate mixing. The extrusion blade is higher, allowing it to agitate the water and flour on the surface, enabling initial mixing.

[0256] After the water and flour are initially mixed, they gradually form dough clumps and small dough balls during stirring. As the mixture is tumbled, smaller particles sink and larger particles rise. Smaller dough balls at the bottom of the first dough are compressed by the extrusion blade, while larger dough balls are compressed by the extrusion blade. The flour and dough clumps are tumbled by the mixing blade, and the flour at the bottom gradually combines completely into dough clumps. The dough clumps and small dough balls at the bottom are then compressed by the mixing unit to form a larger first dough ball. As the first dough ball grows larger, it is compressed by the extrusion blade, gradually forming a complete large dough ball, the second dough ball.

[0257] In summary, the above process allows the water and flour in the container to be fully mixed and form a first dough (i.e., a small dough ball) that can be squeezed by the extrusion blade. Under the action of rotation, the extrusion blade and the inner wall of the container simultaneously form an extrusion cavity to squeeze the first dough ball. This allows the smaller dough balls in the first dough ball to be squeezed at the lower part of the extrusion blade, and as the dough ball formed by the extrusion of the first dough ball grows larger, it can gradually move towards the upper part of the extrusion blade and be squeezed together with the larger dough balls in the first dough ball to form a complete second dough ball, thus completing the entire dough mixing operation.

[0258] For the process of making dough products, please refer to the process description of dough products in Example 2 or Example 3, which will not be repeated here.
