[0036] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0037] Research has found that dough mixers use blades mounted on an internal rotating shaft to stir the flour and water to form a dough. The blades also squeeze the dough, simulating pushing, pulling, and kneading operations to ensure the flour is fully mixed and blended, resulting in a dough that is elastic, stretchable, and flows evenly. However, if the blades are too sharp, they can over-cut the mixed dough during operation, causing it to become lumpy, burred, and evenly stretched.

[0038] The defects in the above solutions are the results obtained by the inventors after practice and careful research. Therefore, the process of discovering the above problems and the solutions proposed by this disclosure for the above problems below should be the contributions made by the inventors to this disclosure during the disclosure process.

[0039] The following describes some embodiments of the present invention in detail with reference to the accompanying drawings. The following embodiments and features thereof may be combined with one another unless they conflict. Furthermore, in the accompanying drawings, the thickness of components may be exaggerated or reduced to effectively illustrate the technical content.

[0040] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0041] Based on the above research, Figure 4 The embodiment of the present disclosure provides a stirring shaft, including: a main shaft 1, the main shaft 1 is cylindrical as a whole, and a plurality of stirring blades 2 are axially arranged on the main shaft 1. When the main shaft 1 rotates, the stirring blades 2 can stir the flour and beat the dough formed after mixing.

[0042] Reference Figure 4 In at least one embodiment, the mixing blade 2 also has at least one dough cone block 21, preferably two, and the two dough cone blocks 21 are mirror-mounted on both sides of the mixing blade 2, so that the mixing blade 2 can mix the flour through the dough cone blocks 21 in the corresponding direction regardless of whether it is installed upright or inverted. At the same time, the dough cone block 21 is integrally connected to the mixing blade 2, and the end of the dough cone block 21 away from the mixing blade 2 is a narrow end, and the narrow end of the dough cone block 21 is an arc-shaped surface, that is, the contact part of the dough cone block 21 with the flour or dough is not a sharp corner. Through the above-mentioned arrangement, when the main shaft 1 drives the mixing blade 2 to rotate, the dough cone block 21 stirs and hits the dough through the arc-shaped surface, thereby avoiding the sharp corners of the dough cone block 21 cutting the mixed dough when the mixing blade 2 rotates, thereby avoiding the dough from having many lumps, burrs, and strands.

[0043] Reference Figure 4 In some embodiments, the dough kneading cone 21 includes a striking arc surface 22 and two guiding inclined surfaces 23, and the two guiding inclined surfaces 23 are mirror-imaged on both sides of the striking arc surface 22. The connection between the guiding inclined surfaces 23 and the striking arc surface 22 is smoothly arranged. Through the above arrangement, the narrow end formed by the striking arc surface 22 is used to strike the dough. The striking arc surface 22 extends through the guiding inclined surfaces 23 and is connected to the mixing blade 2. At the same time, when the mixing blade 2 rotates, the flour and dough are guided to turn outward through the guiding inclined surfaces 23, thereby promoting flour mixing and exerting pushing, pulling, and kneading effects on the dough.

[0044] Reference Figure 4 In some embodiments, the mixing blade 2 further includes a transition camber 24, and the two guiding slopes 23 are connected to the transition camber 24 on the side away from the striking camber 22. When two dough cone blocks 21 are provided, the two dough cone blocks 21 are respectively mounted on either side of the two transition cambers 24, and the two guiding slopes 23 of each dough cone block 21 are respectively connected to the two transition cambers 24 to avoid sharp corners.

[0045] Reference Figure 4 In at least one embodiment, cleaning blades 11 are mounted on each end of the main shaft 1. The cleaning blades 11 are tilted toward each end of the main shaft 1 to form cleaning slopes. When the main shaft 1 rotates within the closed cavity, the cleaning slopes of the two cleaning blades 11 can be positioned in the direction of rotation of the main shaft 1. This allows the cleaning slopes of the cleaning blades 11 to scrape away flour or dough adhering to the inner wall of the cavity as the main shaft 1 rotates, reducing the difficulty of subsequent cleaning.

[0046] Reference Figure 1 The present disclosure provides a dough mixer using the stirring shaft described above. The dough mixer further includes a silo 3 comprising a bottom silo 31 and a top silo 32, each of which is separately provided. One side of the top silo 32 is hinged to the bottom silo 31, and the stirring shaft is rotatably mounted on the bottom silo 31. When the top silo 32 is closed over the bottom silo 31, a complete closed chamber is formed. The stirring shaft can rotate within the chamber to achieve a dough kneading effect. At the same time, a cleaning blade 11 is in contact with the inner side walls of the top silo 32 and the bottom silo 31, so that when the stirring shaft rotates, the cleaning blade 11 can clean flour or dough adhering to the inner side walls of the top silo 32 and the bottom silo 31.

[0047] Reference Figure 3 In at least one embodiment, the top bin 32 has a feeding port 33 on the side away from the bottom bin 31, that is, the top of the top bin 32 is provided with a feeding port 33, and flour and water can be fed into the silo 3 through the feeding port 33. At the same time, the top bin 32 also has a top cover 34, one side of the top cover 34 is hinged to the top bin 32, and the top cover 34 corresponds to the feeding port 33. The top cover 34 can cover or open the feeding port 33. Specifically, under normal circumstances, the top bin 32 and the bottom bin 31 of the silo 3 are covered. At this time, the top cover 34 is opened to feed the material into the feeding port 33. Then, the top cover 34 is closed to close the feeding port 33 to prevent external debris from entering during the subsequent kneading of the dough. When the interior of the silo 3 needs to be cleaned, the equipment that is generally arranged as a whole is more troublesome for cleaning the interior of the equipment. By dividing the silo 3 into a top silo 32 and a bottom silo 31, the top silo 32 can be separated from the bottom silo 31 during cleaning, thereby completely opening the interior space of the silo 3, greatly reducing the difficulty of cleaning and facilitating the installation and disassembly of the stirring shaft.

[0048] Reference Figure 3In some embodiments, to assist in manually lifting the top bin 32, a lid-opening cylinder 35 is provided on one side of the bottom bin 31. The lid-opening cylinder 35 is hinged to the bottom bin 31, and the movable end of the lid-opening cylinder 35 is hinged to the top bin 32. With this arrangement, when the lid-opening cylinder 35 is activated, it can push the top cover 34 up around the hinge. Conversely, when the lid-opening cylinder 35 is activated, it can pull the top bin 32 down and close it with the bottom bin 31.

[0049] Reference Figure 2 In some embodiments, to drive the main shaft 1, a drive motor 36 is mounted on one side of the bottom bin 31. The movable end of the drive motor 36 is in driving connection with the agitator shaft. Specifically, a pulley can be mounted on one end of the main shaft 1, and the drive cylinder engages with the pulley via a belt, thereby driving the main shaft 1.
