[0033] Referring to Figures 1 to 4 the drawings, an asynchronous stirring structure according to an embodiment of the first aspect of the present utility model includes:
[0034] The stirring drive assembly 100 includes a motor 110, a main rotating shaft 120, a driving disc 130, a first driven rotating shaft 140, a first driven gear 141, a second driven rotating shaft 150, and a second driven gear 151. The main rotating shaft 120, the first driven rotating shaft 140, and the second driven rotating shaft 150 are parallel to each other. The driving disc 130 is coaxially and fixedly connected to the main rotating shaft 120. The main rotating shaft 120 is connected to the motor 110 through a coupling. The motor 110 is used to drive the main rotating shaft 120 to rotate. The driving disc 130 rotates synchronously with the main rotating shaft 120. A plurality of driving gear teeth 131 are arranged on the circumferential surface of the driving disc 130 along an arc. The driving gear teeth 131 are respectively matched with the first driven gear 141 and the second driven gear 151. The first driven gear 141 is coaxially and rotatably connected to the first driven rotating shaft 140. The second driven gear is coaxially and rotatably connected to the second driven rotating shaft 150. The first driven gear 141 and the second driven gear 151 are respectively located on both sides of the circumferential surface of the driving disc 130. Under the drive of the motor 110, the rotating driving gear teeth 131 are respectively meshed with the first driven gear 141 and the second driven gear 151 at different times, so that the driving gear teeth 131 drive the first driven gear 141 and the second driven gear 151 to rotate around their respective axes in different time periods;
[0035] The first stirring assembly 200 includes a first toothed ring 210 and a first stirring paddle 220. The first driven gear 141 is meshed with the first toothed ring 210. The first stirring paddle 220 is connected to the first toothed ring 210. The first stirring paddle 220 rotates with the first toothed ring 210. The rotation radius of the first stirring paddle 220 is R1;
[0036] The second stirring assembly 300 includes a second toothed ring 310 and a second stirring paddle 320. The second driven gear 151 is meshed with the second toothed ring 310. The second stirring paddle 320 is connected to the second toothed ring 310. The second stirring paddle 320 rotates with the second toothed ring 310. The rotation radius of the second stirring paddle 320 is R2, and R2≠R1, which can avoid the collision and damage between the first stirring paddle 220 and the second stirring paddle 320.
[0037] The driving wheel teeth 131 arranged along the arc segment are driven by the motor 110 and the main rotating shaft 120. The driving wheel teeth 131 can be respectively meshed and connected with the first driven gear 141 and the second driven gear 151 in different time periods, so as to realize the asynchronous driving of the first driven gear 141 and the second driven gear 151 to rotate. When the first driven gear 141 rotates, it drives the first toothed ring 210 and the first stirring paddle 220 connected thereto to rotate. When the second driven gear 151 rotates, it drives the second toothed ring 310 and the second stirring paddle 320 connected thereto to rotate, enabling the first stirring paddle 220 and the second stirring paddle 320 to rotate in different time periods. The first stirring paddle 220 and the second stirring paddle 320 operating asynchronously can cooperate to limit and stir the material, effectively improving the uniformity of stirring and mixing, with good stirring and mixing effects. Moreover, the respective rotation radii of the first stirring paddle 220 and the second stirring paddle 320 are not equal, enabling the stirring and mixing of materials in different dimensions, and further improving the uniformity of stirring and mixing.
[0038] It can be understood that both the first toothed ring 210 and the second toothed ring 310 are internal toothed rings. The first driven gear 141 is meshed and connected to the inner side of the first toothed ring 210, and the second driven gear 151 is meshed and connected to the inner side of the second toothed ring 310. Correspondingly, the driving disc 130 is arranged inside the first toothed ring 210 and the second toothed ring 310. By arranging the corresponding gear structure inside the toothed ring, the space utilization rate can be effectively improved, thereby effectively controlling the size of the overall structure and facilitating the layout and use design of this asynchronous stirring structure.
[0039] It can be understood that the first toothed ring 210 is located above the second toothed ring 310, R1 > R2, and the first stirring paddle 220 rotates outside the range surrounded by the rotation path of the second stirring paddle 320, that is, the first stirring assembly 200 is arranged to cover the second stirring assembly 300, which can effectively avoid collisions between the stirring paddles and the driven gears and effectively improve the motion reliability of the overall asynchronous stirring structure.

The tooth width refers to the length of the entity of the gear tooth in the axial direction. Usually, the thickness of the gear is equal to the tooth width. By setting the tooth width of the driving gear 131 to be greater than the sum of the tooth widths of the first driven gear 141 and the second driven gear 151, it can be effectively ensured that the driving gear 131 can be respectively meshed and connected with the first driven gear 141 and the second driven gear 151 at different horizontal heights.
[0041] Only by increasing the tooth width dimension of the driving gear tooth 131 can the linkage with the two driven gears be realized respectively. The first driven gear 141 and the second driven gear 151 can be set to small sizes, which can effectively save the use of materials and thus reduce the manufacturing cost of this asynchronous stirring structure.
[0042] It can be understood that the central angle of the arc where the driving gear tooth 131 is located is less than or equal to 180 degrees. The first driven gear 141 and the second driven gear 151 are respectively located on opposite sides of the driving disc 130. The driving gear 131 is meshed and connected with the first driven gear 141 and the second driven gear 151 respectively at different time periods within the same rotation cycle.
[0043] When the first driven gear 141 rotates, the second driven gear 151 is stationary, which can effectively ensure that when the first stirring paddle 220 rotates, the second stirring paddle 320 is stationary. At this time, the first stirring paddle 220 stirs and mixes the materials, and the second stirring paddle 320 acts as a limiting obstacle to hinder the movement of the materials. By using one stationary and one moving stirring paddle, the stirring and mixing effect of the materials can be improved.

When the first tooth ring 210 rotates, it drives the first paddle rod 221 to rotate, so that the first paddle blades 222 rotate accordingly, and the materials can be fully stirred and mixed; the second stirring paddle 320 includes a second paddle rod 321 and a plurality of second paddle blades 322. All the second paddle blades 322 are connected to the second paddle rod 321, and the second paddle rod 321 is connected to the second tooth ring 310. When the second tooth ring 310 rotates, it drives the second paddle rod 321 to rotate, so that the second paddle blades 322 rotate accordingly, and the materials can be fully stirred and mixed.
[0045] It can be understood that there are two first stirring paddles 220 in the first stirring assembly 200, and the two first stirring paddles 220 are axisymmetric about the center of the first tooth ring 210, which can improve the stirring and mixing efficiency of the materials; there are two second stirring paddles 320 in the second stirring assembly 300, and the two second stirring paddles 320 are axisymmetric about the center of the second tooth ring 310, which can improve the stirring and mixing efficiency of the materials.
