[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0036] Example 1

[0037] Refer to Figure 1 and Figure 2, this embodiment discloses a dough mixing paddle, which includes a rotating shaft 1, a first paddle blade 2, and a second paddle blade 3. Among them, the rotating shaft 1 can rotate around its own central axis. The first paddle blade 2 is arranged at the bottom end of the outer side wall of the rotating shaft 1 and can rotate following the rotating shaft 1. The second paddle blade 3 is arranged at the bottom end of the outer side wall of the rotating shaft 1 and can rotate following the rotating shaft 1. The first paddle blade 2 and the second paddle blade 3 are arranged oppositely, and along the axial direction of the rotating shaft 1, the height of the second paddle blade 3 is greater than that of the first paddle blade 2, and along the radial direction of the rotating shaft 1, the length of the lower part of the second paddle blade 3 is greater than that of its upper part.

[0038] The rotating shaft 1 is a cylindrical structure, and the direction of the central axis of the rotating shaft 1 is the extending direction of the rotating shaft 1. The outer side wall of the rotating shaft 1 is an arc-shaped structure. Both the first paddle blade 2 and the second paddle blade 3 are arranged at the bottom end of the outer side wall of the rotating shaft 1, that is, along the axial direction of the rotating shaft 1, the bottom ends of the first paddle blade 2 and the second paddle blade 3 are at the same level and slightly higher than the bottom end of the rotating shaft 1, so that after the dough mixing paddle is installed on the dough mixing assembly, the bottom ends of the first paddle blade 2 and the second paddle blade 3 are designed to be suspended to ensure the smooth rotation of the dough mixing paddle.

[0039] The rotating shaft 1, the first paddle blade 2, and the second paddle blade 3 are of an integral structure. This dough mixing paddle has a simple structure, is convenient to manufacture, and can greatly reduce the manufacturing cost. Moreover, since the heights of the first paddle blade 2 and the second paddle blade 3 along the axial direction of the rotating shaft 1 are different, and the lengths of the upper and lower parts of the second paddle blade 3 along the radial direction of the rotating shaft 1 are different, the dough can be evenly and fully squeezed and stirred through the cooperation of the paddle blades with different heights and different lengths, improving the dough forming speed and the dough mixing efficiency.

[0040] Specifically, the second paddle blade 3 includes a vertical section 31 and a horizontal section 32. Along the radial direction of the rotating shaft 1, the length of the horizontal section 32 is greater than that of the vertical section 31. The vertical section 31 is located above the horizontal section 32, and the vertical section 31 and the horizontal section 32 are connected by an arc transition. Designing the vertical section 31 and the horizontal section 32 with different widths can squeeze and stir the dough more evenly. The arc transition connection structure avoids shearing the dough to affect the forming effect.

[0041] On this basis, along the radial direction of the rotating shaft 1, the length of the first paddle blade 2 is greater than that of the vertical section 31. The length of the first paddle blade 2 along the radial direction of the rotating shaft 1 can be the same as or different from the length of the horizontal section 32. Thus, the diversity of the length of the paddle blade along the radial direction of the rotating shaft 1 can be increased, thereby increasing the diversity of the extrusion force and making the extrusion and stirring of the paddle blade on the dough more uniform.

[0042] Further, along the axial direction of the rotation axis 1, the height of the first paddle 2 is less than the height of the vertical section 31 and greater than the height of the horizontal section 32. In this way, the paddles of the dough mixing paddle have diversity in both the length along the radial direction of the rotation axis 1 and the height along the axial direction of the rotation axis 1. The cooperation between the first paddle 2 and the second paddle 3 can provide various extrusion forces in all aspects, making the extrusion and agitation of the dough by the dough mixing paddle closer to the manual dough mixing method, the dough being more evenly stressed, the forming speed being faster, which is beneficial to improving the dough mixing efficiency and the dough forming effect.

[0043] Specifically, along the axial direction of the rotation axis 1, the height from the top end of the vertical section 31 to the bottom end of the second paddle 31 is H1, the height from the top end of the horizontal section 32 to the bottom end of the second paddle 31 is H2, and the height from the top end to the bottom end of the first paddle 2 is H3. Along the radial direction of the rotation axis 1, the length of the vertical section 31 is L1, the length of the horizontal section 32 is L2, and the length of the first paddle 2 is L3. Among them, H1 = (2 - 4)H2, H1 = (2 - 4)H3, and H3 > H2; L1 = (2 - 4)L2, L3 > L1. In this way, the paddles of the dough mixing paddle have three heights along the axial direction of the rotation axis 1 and three lengths along the radial direction of the rotation axis 1, and as the height decreases, the length of the paddle increases, so that a greater extrusion force can be given to the broken dough at the lower part to accelerate the formation of the broken dough into a large dough, and then the large dough is evenly extruded and agitated through the upper part, which can not only have high dough mixing efficiency, but also improve the dough forming effect.

[0044] On the basis of the above structure, referring to Figure 3 , along the radial and / or axial direction of the rotation axis 1, the first paddle 2 and the second paddle 3 are bent in the same direction in an arc to form an arc-shaped paddle surface. Both the first paddle 2 and the second paddle 3 are arc-shaped paddles. When the dough mixing paddle performs the dough mixing operation, the arc-shaped convex surfaces of the first paddle 2 and the second paddle 3 push and extrude the dough, similar to the manual dough mixing method, which can fully extrude the dough in the radial and / or axial direction and further improve the dough forming effect.

[0045] In addition, a baffle 4 is provided on the outer periphery of the rotation axis 1 in the radial direction, and the baffle 4 is located above the second paddle 3. The setting of the baffle 4 can prevent the broken dough from splashing upward, so that the broken dough quickly falls back to be extruded and agitated, thereby accelerating the formation of the dough.

[0046] Embodiment 2

[0047] Referring to Figure 4 , this embodiment discloses a dough mixing assembly, including: a dough bucket 5 and the dough mixing paddle of Embodiment 1, and the dough mixing paddle is rotatably installed on the bottom wall of the dough bucket 5.

[0048] When performing the dough-kneading operation, flour and water in appropriate proportions are put into the dough bucket 5, and the dough-kneading paddle rotates relative to the dough bucket 5 to perform the dough-kneading operation. When the dough-kneading paddle rotates and squeezes and stirs the dough, it will drive the dough to rotate and contact the inner wall of the dough bucket 5. Since the heights of the first paddle blade 2 and the second paddle blade 3 along the axial direction of the rotating shaft 1 are different, and the lengths of the upper and lower parts of the second paddle blade 3 along the radial direction of the rotating shaft 1 are different, the dough can be evenly and fully squeezed and stirred by the cooperation of the paddle blades with different heights and lengths and the dough bucket 5, and various different intensities of extrusion forces can be provided when squeezing and stirring the dough, which not only improves the dough-forming speed and the dough-kneading efficiency, but also makes the dough-kneading operation closer to the manual method, thereby improving the forming effect of the dough.

[0049] Furthermore, at least one rib 6 is provided on the inner wall of the dough bucket 5, and the rib 6 extends along the axial direction of the rotating shaft 1. The first paddle blade 2 and the second paddle blade 3 are both arranged at a distance from the rib 6. In this embodiment, a plurality of ribs 6 are arranged at intervals. Since the first paddle blade 2 and the second paddle blade 3 have various lengths along the radial direction of the rotating shaft 1, there are various distances between the paddle blades and the rib 6, thereby further increasing the diversity of the extrusion force intensity on the dough and making the forming effect of the dough better.

[0050] And, referring to Figure 5 , along the axial direction of the rotating shaft 1, the height of the rib 6 is the same as the height of the second paddle blade 3. In this way, the first paddle blade 2 and the second paddle blade 3 can cooperate with the rib 6 to squeeze the dough at any height.

[0051] For the rotational installation of the dough-kneading paddle and the dough bucket 5, referring to Figure 6 , a mounting shaft 7 is provided on the bottom wall of the dough bucket 5, and a bushing 11 is provided at the bottom of the rotating shaft 1. The bushing 11 is rotatably sleeved on the mounting shaft 7. A mounting hole is opened at the center of the bottom wall of the dough bucket 5, and the mounting shaft 7 passes through the mounting hole and is fixedly connected to the bottom wall of the dough bucket 5. This fixed connection can be welding, threaded connection, etc. The bushing 11 is provided with an adapted connection hole corresponding to the mounting shaft 7 to enable the bushing 11 to be sleeved outside the mounting shaft 7 through the connection hole, and the bushing 11 can rotate relative to the mounting shaft 7. The bushing 11 is fixedly connected to the rotating shaft 1, and the rotating shaft 1 rotates synchronously with the bushing 11, thereby realizing the rotation of the rotating shaft 1 relative to the dough bucket 5.

It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches are also regarded as the protection scope of the present utility model.
