[0045] With reference to Figure 3 , specifically, the rotating assembly 34 comprises a driving gear 341 and a driven gear 342 which are engaged with each other, wherein the driving gear 341 is driven to rotate by an external power source 343, so as to drive the driven gear 342 to rotate. The external power source 343 is also mainly realized by a motor, and the motor is fixedly installed on the hanger 5. The moving rod 331 is coaxially fixedly installed on the driven gear 342, one end of the moving rod 331 penetrates through the driven gear 342, and the hanger 5 is provided with a guide rail for inserting one end of the moving rod 331.

[0046] With reference to Figure 3 and Figure 4The upper end of the moving rod 331 is provided with a bearing plate 3311 which is slidingly installed on a guide rail, and the guide rail is provided with a guide strip 51 which is in close contact with the bearing plate 3311, so that the whole moving rod 331 is hung on the guide rail.

Although the dough is mechanically kneaded, the effect of manually kneading the dough can be achieved, so as to improve the shape regularity and quality of the dough.

[0050] Embodiment 2

[0051] With reference to Figure 5 The embodiment of the application further comprises a powder spraying mechanism 6 which is composed of a powder storage box 61, a powder spraying box 62 and a powder falling channel 63. The moving rod 331 is fixedly connected with a plate, the powder storage box 61 is fixedly installed on the plate, and a plug is inserted into the powder storage box 61. The plug can be opened to add powdery objects such as flour and yeast. The powder storage box 61 is used to store flour and is fixedly installed on the moving rod 331 and can move together with the moving rod 331. The powder spraying box 62 is embeddedly installed in the blocking ring 321 of the kneading plate 32.

[0052] With reference to Figure 5The powder spraying box 62 is provided with a plurality of powder outlets and an air inlet on opposite sides. The powder spraying box 62 is connected to the flour storage box 61 through a flour falling channel 63, so that the flour can flow from the flour storage box 61 to the powder spraying box 62. Meanwhile, the air inlet of the powder spraying box 62 is also connected to an air injection pipe 623, which is further connected to an air source. The air source is also fixedly installed on the moving rod 331. The air source blows air to the powder spraying box 62 through the air injection pipe, so that the flour is sprayed out of the powder outlet 621. Part of the flour falls on the dough, and part of the flour falls on the second conveying belt 22, realizing the function of automatically adding flour to the dough.

[0053] The air injection pipe is spirally arranged and can be stretched or compressed along with the lifting of the kneading plate 32.

[0054] The air source adopts a rechargeable miniature air pump. The battery of the rechargeable air pump can be charged and stored.

[0055] In order to further control the amount and timing of flour spraying, with reference to Figure 5 and Figure 6 , the embodiment also includes an opening and closing assembly 7. The assembly is composed of a blocking block 71, an elastic member 72, a push block 73 and a push rod 74. The blocking block 71 is used to block the flour outlet 621 of the flour storage box 61, and the push block 73 is connected to the blocking block 71 and partially extends out of the flour storage box 61. The flour storage box 61 is also provided with a vertical slot 611 for sliding the push block 73. In order to make the blocking block 71 always have the tendency to block the flour outlet 621, the blocking force is provided by the elastic member 72. The elastic member 72 is a compression spring, one end of which is fixedly connected to the plate, and the other end of which is fixedly connected to the push block 73. The flour storage box 61 is also provided with a vertical slot 611 for sliding the push block 73. The push rod 74 is installed on the lifting rod 332, and when the lifting rod 332 is lifted, the push rod 74 moves, thereby pushing the push block 73 to slide in the vertical slot 611, and further changing the blocking state of the blocking block 71 to the flour outlet 621. Only the flour in the flour falling channel 63 and the powder spraying box 62 can be sprayed out, so as to realize the precise control of flour spraying.

[0056] The moving rod 331 penetrates the push block 73, and the compression spring is sleeved on the moving rod 331. The moving rod 331 can also guide the extension direction of the compression spring.

[0057] With reference to Figure 5 and Figure 6In order to prevent the flour in the flour storage box 61 from overflowing from the vertical groove 611, the push block 73 is provided with a baffle 75 for always blocking the vertical groove 611. The baffle 75 is located in the flour storage box 61, and the part of the baffle 75 in contact with the flour in the flour storage box 61 is not in contact with the outside, so that the inside of the flour storage box 61 can be kept clean. When the baffle 75 moves up and down with the push block 73, in order to provide the baffle 75 with a sliding space, the bottom of the flour storage box 61 extends a receiving box 612, and the lower end of the baffle 75 is inserted into the receiving box 612. The receiving box 612 is only for the insertion of the baffle 75, and the flour is not easy to enter the receiving box 612. The cooperation of the baffle 75 and the receiving box 612 enables the baffle 75 to stably move up and down with the push block 73.

[0058] With reference to Figure 5 The embodiment of the present application further optimizes the flour spraying mechanism 6. Specifically, the flour falling channel 63 comprises a first flour falling pipe 631 and a second flour falling pipe 632 which are in communication with each other. One end of the first flour falling pipe 631 is in communication with the flour storage box 61, and the other end is connected with the second flour falling pipe 632. One end of the second flour falling pipe 632 is fixedly installed on the kneading plate 32, and the material thereof is a flexible material such as rubber or silica gel. Such a flexible material enables the second flour falling pipe 632 to deform during the lifting and lowering of the kneading plate 32, thereby further controlling the spraying amount and spraying range of the flour.

[0059] When the kneading plate 32 is kneading the dough downward, the second flour falling pipe 632 is constantly straightened, which can shake the flour in the first flour falling pipe 631 and the second flour falling pipe 632, so that the flour can smoothly enter the flour spraying box 62.

[0060] The above are the preferred embodiments of the present application, and do not limit the protection scope of the present application.
