[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] See also Figures 1-9 The stirring blade assembly includes a driving motor 1, a first stirring blade 2 and a second stirring blade 3 arranged on the outside of the first stirring blade 2. A transmission mechanism is provided between the driving motor 1 and the first stirring blade 2 and the second stirring blade 3. The driving motor 1 causes the first stirring blade 2 and the second stirring blade 3 to rotate around the center position of the transmission mechanism respectively through the transmission mechanism. The first stirring blade 2 and the second stirring blade 3 can stir and fuse the food ingredients at the same time under the action of the driving motor 1 and the transmission mechanism. Since the second stirring blade 3 is arranged on the outside of the first stirring blade 2, the stirring range of the food ingredients can be relatively increased, which is beneficial to improving the production efficiency of the equipment.

[0029] Furthermore, there is no need to configure two additional drive devices for the first stirring blade 2 and the second stirring blade 3 , thereby simplifying the overall structure of the equipment and reducing the production cost of the equipment.

[0030] Preferably, the drive motor 1 is electrically connected to an electric control mechanism for facilitating a user to control the working state of the drive motor 1 .

[0031] The first stirring blade 2 includes a central rotating shaft 21 and a spiral blade 22. The central rotating shaft 21 is connected to the transmission mechanism. The spiral blade 22 is arranged on the outside of the central rotating shaft 21 in a spiral shape. The spiral blade 22 is fixedly connected to the central rotating shaft 21. The driving motor 1 can drive the spiral blade 22 to rotate in the positive direction through the central rotating shaft 21. During the forward rotation of the spiral blade 22, it can not only stir the food, but also push the food downward, thereby improving the food discharge efficiency.

[0032] The second stirring blade 3 includes a transmission disk 31 and an outer blade 32. The transmission disk 31 is connected to the transmission mechanism. The outer blade 32 is arranged in the radial outer direction of the first stirring blade 2. The outer blade 32 is fixedly connected to the transmission disk 31. The driving motor 1 can drive the outer blade 32 to rotate through the transmission mechanism and the transmission disk 31. The rotation of the outer blade 32 can stir the food in the radial outer direction of the first stirring blade 2, thereby relatively increasing the stirring range of the food raw materials.

[0033] The outer blades 32 are provided with a scraping bevel 321 at the front side relative to the rotation direction of the outer blades 32. The scraping bevel 321 is arranged to be inclined from the inside to the outside along the rotation direction of the outer blades 32. The outer blades 32 can scrape the food ingredients off the cylinder wall through the scraping bevel 321, reducing the chance of food ingredients remaining on the cylinder wall. This not only improves the efficiency of stirring the food ingredients, but also reduces the chance of hygienic problems caused by food ingredients remaining on the cylinder wall for a long time.

[0034] The second stirring blade 3 also includes a limiting ring 33, which is arranged on the outer side of the lower section of the spiral blade 22. The limiting ring 33 is fixedly connected to the outer blade 32. The limiting ring 33 can improve the structural stability of the outer blade 32 and reduce the chance of deformation of the outer blade 32. At the same time, the limiting ring 33 can make the food raw materials more concentrated when the spiral blade 22 pushes the food raw materials downward, and the food discharge efficiency is further improved.

[0035] A guide ramp 34 is provided between the lower side of the outer blade 32 and the limit ring 33. The guide ramp 34 is arranged to be tilted downward along the rotation direction of the outer blade 32, so that the food materials between the lower side of the outer blade 32 and the lower limit ring 33 can be lifted up again and stirred again, which can prevent the food materials from staying between the lower side of the outer blade 32 and the lower limit ring 33 for a long time and improve the utilization efficiency of the food materials.

[0036] The transmission mechanism includes a housing 41, a transmission shaft 42 and a plurality of transmission gears 43. The upper and lower ends of the transmission shaft 42 are respectively connected to the drive motor 1 and the central shaft 21. The outer side of the transmission shaft 42 is provided with a shaft gear 44. The inner side of the transmission plate 31 has a tooth structure corresponding to the transmission gear 43. The transmission gear 43 is respectively connected to the shaft gear 44 and the transmission plate 31. A transmission shaft (not shown in the figure) is provided at the center of the transmission gear 43. The transmission shaft is movably connected to the housing 41. The transmission gear 43 is relatively The shell 41 is stationary in the circumference and rotates around the transmission shaft. The shaft gear 44 can drive the transmission plate 31 to rotate around the central shaft 21 through the transmission gear 43. When the driving motor 1 rotates the spiral blade 22 in the forward direction through the central shaft 21, the shaft gear 44 also rotates in the forward direction. The transmission gear 43 rotates in the reverse direction under the action of the shaft gear 44. The transmission plate 31 rotates in the reverse direction under the action of the transmission gear 43, thereby causing the outer blade 32 to rotate around the transmission shaft 42 in the reverse direction.

[0037] During operation, the spiral blades 22 and the outer blades 32 rotate in the forward and reverse directions respectively around the transmission shaft 42, so that the food ingredients are subjected to opposite forces at different positions simultaneously, thereby further improving the effect of stirring the food ingredients.

[0038] A plurality of transmission gears 43 are evenly distributed along the circumference between the shaft gear 44 and the transmission disc 31. Each transmission gear 43 is respectively connected and cooperated with the shaft gear 44 and the transmission disc 31, so that the force at different positions between the shaft gear 44 and the transmission disc 31 is more uniform, thereby improving the stability of the operation of the transmission disc 31.

[0039] A limiting convex edge 421 is provided on the outer side of the transmission shaft 42 corresponding to the lower position of the transmission disk 31. The lower side of the transmission disk 31 abuts against the limiting convex edge 421 and can slide with each other. The limiting convex edge 421 can support the transmission disk 31. There is no need to set up an additional assembly structure corresponding to the transmission disk 31 in the equipment, which simplifies the overall installation structure of the stirring blade assembly.

[0040] The lower side of the transmission disc 31 is provided with several elastic buckles 311 distributed along the outer circumference of the transmission shaft 42. The elastic buckles 311 are L-shaped, and the horizontal inner side of the elastic buckle 311 is adjacent to the outer side of the transmission shaft 42. The lower side of the elastic buckle 311 abuts against the limiting convex edge 421 and can slide with each other. The transmission disc 31 can abut against the limiting convex edge 421 through the elastic buckle 311, thereby increasing the vertical distance between the transmission disc 31 and the spiral blade 22 and reducing the chance of interference between the two. The elastic buckle 311 can also have a certain limiting effect on the transmission shaft 42, so that the center coincidence effect of the transmission disc 31 and the transmission shaft 42 is better, further improving the stability of the transmission disc 31 during rotation.

[0041] The elastic buckle 311 is provided with a first guide bevel 3111 on the side facing the central rotating shaft 21, and a second guide bevel 4211 corresponding to the first guide bevel 3111 is provided on the lower side of the limiting convex edge 421. The first guide bevel 3111 and the second guide bevel 4211 are respectively inclined upward from the inside to the outside. During installation, the transmission shaft 42 passes through the transmission disk 31 from top to bottom. Under the action of the first guide bevel 3111 and the second guide bevel 4211, the smoothness of the limiting convex edge 421 passing through the elastic buckle 311 can be improved. After the limiting convex edge 421 passes through the elastic buckle 311, the elastic buckle 311 is reset to play an anti-slip effect, thereby realizing quick installation between the transmission shaft 42 and the transmission disk 31.
