[0027] Specifically, the rotating member includes a main shaft 3, a large gear 7, a gear cover 8 and a gear bracket 4. The gear bracket 4 is arranged in the gear cover 8. The large gear 7 is sleeved outside the gear bracket 4, and the large gear 7 is slidably connected to the gear bracket 4, that is, the large gear 7 can rotate relative to the gear bracket 4.

[0028] Further, when the dough kneading device is installed, the large gear 7 is fixed in the container. Based on the main shaft 3 driving the gear bracket 4 to rotate, the gear bracket 4 rotates in the large gear 7, and the axis of the main shaft 3 is the central axis of the dough kneading device. The first dough kneading hook 1 and the second dough kneading hook 2 can realize the revolving rotation around the central axis along with the rotation of the gear bracket 4.

[0029] One end of the main shaft 3 is connected inside the gear bracket 4, and the other end of the main shaft 3 is connected to a driving member. Based on the driving member driving the main shaft 3 to rotate, the gear bracket 4 is driven to rotate.

[0030] Further, the driving member can be a driving motor or a driving cylinder, which can be adjusted according to actual assembly requirements.

[0031] Specifically, a first installation groove and a second installation groove are provided inside the gear bracket 4.

The first kneading hook 1 is fitted in the first installation groove based on the fitting connecting shaft 9, and the second kneading hook 2 is fitted in the second installation groove based on the fitting connecting shaft 9. When the main shaft 3 rotates driven by a driving component, the gear bracket 4 can be driven to rotate, thereby driving the first kneading hook 1 and the second kneading hook 2 to rotate around the central axis of the kneading device, so as to realize the revolution rotation of the first kneading hook 1 and the second kneading hook 2.

[0032] Specifically, the first sub-driving mechanism includes a first small gear 5. The first small gear 5 is fixed at the top end of the fitting connecting shaft 9 in the first installation groove. The first small gear 5 meshes with the large gear 7. When the main shaft 3 drives the gear bracket 4 to rotate, the first small gear 5 can move along the inner wall of the large gear 7. Based on the meshing of the first small gear 5 and the large gear 7, the first small gear 5 can realize self-rotation when rotating based on the gear bracket 4, thereby driving the first kneading hook 1 to rotate.

[0033] Specifically, the second sub-driving mechanism includes a second small gear 6. The second small gear 6 is fixed at the top end of the fitting connecting shaft 9 in the second installation groove. The second small gear 6 meshes with the large gear 7.

[0039] Specifically, the first kneading hook 1 is provided with a first arc segment, and the second kneading hook 2 is provided with a second arc segment. The curvature of the first arc segment is smaller than that of the second arc segment, and the size of the first kneading hook 1 is smaller than that of the second kneading hook 2, such that the rotation areas of the first kneading hook 1 and the second kneading hook 2 can cover most of the space of the container, thereby meeting the requirement for kneading and shaping the dough by the first kneading hook 1 and the second kneading hook 2.

[0040] Specifically, a preset angle is provided between the first kneading hook 1 and the second kneading hook 2, such that the first kneading hook 1 and the second kneading hook 2 can be misaligned with each other during rotation, avoiding the situation of movement interference between the first kneading hook 1 and the second kneading hook 2 and improving the reliability of the kneading process of the first kneading hook 1 and the second kneading hook 2.

[0041] Further, the first pinion gear 5 and the second pinion gear 6 are gear structures with the same size. The first pinion gear 5 and the second pinion gear 6 are symmetrically distributed on the gear bracket 4, and the first pinion gear 5 and the second pinion gear 6 are in contact with the internal teeth of the large gear 7, enabling the first pinion gear 5 and the second pinion gear 6 to rotate synchronously at the same rate and in the same direction, so that when the first kneading hook 1 and the second kneading hook 2 rotate, they can maintain a preset angle and avoid the situation of movement interference.
