[0038] Reference Figure 2 According to an embodiment of the present application, the stirring device includes: a stirring barrel 100, a stirring blade assembly and a stirring driver 400.

[0039] Reference Figure 3 and Figure 4The inner wall surface of the bottom of the mixing barrel 100 forms a guide surface 110, and the guide surface 110 is arc-shaped so that the diameter of the bottom of the mixing barrel 100 decreases from top to bottom. The bottom of the mixing barrel 100 is provided with a discharge port 120, and the top of the mixing barrel 100 is provided with a feed port 130;

[0040] Reference Figure 3 and Figure 4 The stirring blade assembly includes a first stirring blade 200 and a second stirring blade 300. The first stirring blade 200 and the second stirring blade 300 are horizontally distributed in the stirring barrel 100, and the first stirring blade 200 and the second stirring blade 300 are symmetrically arranged; the first stirring blade 200 forms a first stirring surface 221 on the side close to the inner wall of the stirring barrel 100, and the second stirring blade 300 forms a second stirring surface 321 on the side close to the inner wall of the stirring barrel 100. The first stirring surface 221 and the second stirring surface 321 are arc-shaped;

[0041] Reference Figure 2 The stirring driver 400 drives and connects the first stirring blade 200 and the second stirring blade 300 to drive the first stirring blade 200 and the second stirring blade 300 to rotate, wherein the rotation path of the first stirring blade 200 and the second stirring blade 300 passes through the bottom of the stirring barrel 100.

[0042] It can be understood that the raw materials are put into the mixing barrel 100 through the feed port 130 at the top of the mixing barrel 100, and the stirring driver 400 drives the first stirring blade 200 and the second stirring blade 300 to rotate so that the first stirring blade 200 and the second stirring blade 300 stir the raw materials in the mixing barrel 100. It should be understood that the first stirring surface 221 of the first stirring blade 200 and the second stirring surface 321 of the second stirring blade 300 are arc-shaped, and the first stirring blade 200 and the second stirring blade 300 are symmetrically arranged in the horizontal direction, so that the rotation range of the first stirring blade 200 and the second stirring blade 300 is spherical, and the guide surface 110 of the mixing barrel 100 is also arc-shaped, and the guide surface 110 reduces the diameter of the bottom of the mixing barrel 100 from top to bottom, so that the bottom of the mixing barrel 100 is hemispherical, and the rotation path of the first stirring blade 200 and the second stirring blade 300 will pass through the bottom of the mixing barrel 100, so that the rotation range of the first stirring blade 200 and the second stirring blade 300 is adapted to the shape of the bottom of the mixing barrel 100, so as to reduce the stirring dead angle, improve the stirring effect on the raw materials, ensure that the raw materials are stirred evenly, and ensure the color consistency of the product.

[0043] Specifically, the curvature of the first stirring surface 221, the curvature of the second stirring surface 321 and the curvature of the guide surface 110 are adapted to each other. For example, the curvature of the first stirring surface 221, the curvature of the second stirring surface 321 and the curvature of the guide surface 110 are at least partially consistent, so as to reduce the gap between the first stirring surface 221, the second stirring surface 321 and the guide surface 110, thereby further reducing the stirring dead angle of the first stirring blade 200 and the second stirring blade 300.

[0044] It should also be understood that the guide surface 110 reduces the diameter of the bottom of the mixing barrel 100 from top to bottom, and the discharge port 120 of the mixing barrel 100 is arranged at the bottom of the mixing barrel 100, which can facilitate the gathering of raw materials, thereby further improving the stirring effect of the raw materials, and facilitating the discharge of the raw materials from the discharge port 120, so that the raw materials are not easily retained in the mixing barrel 100.

[0045] Specifically, the discharge port 120 of the mixing barrel 100 is disposed at the center of the bottom of the mixing barrel 100 .

[0046] Reference Figure 5 According to some embodiments of the present application, the first stirring blade 200 includes a first fixed portion 210 and a plurality of first blades 220, the first blades 220 are distributed along the circumference on the outside of the first fixed portion 210, and the side of the first blade 220 close to the inner wall of the mixing barrel 100 forms a first stirring surface 221, and the stirring driver 400 drives and connects to the first fixed portion 210; the second stirring blade 300 includes a second fixed portion 310 and a plurality of second blades 320, the second blades 320 are distributed along the circumference on the outside of the second fixed portion 310, and the side of the second blade 320 close to the inner wall of the mixing barrel 100 forms a second stirring surface 321, and the stirring driver 400 drives and connects to the second fixed portion 310.

[0047] It is understood that the stirring driver 400 is connected to the first fixing portion 210 by driving the plurality of first blades 220 to rotate about the axis of the first fixing portion 210, so that the plurality of first blades 220 stir the raw material, thereby enhancing the stirring effect of the raw material. Similarly, the stirring driver 400 is connected to the second fixing portion 310 by driving the plurality of second blades 320 to rotate about the axis of the second fixing portion 310, so that the plurality of second blades 320 stir the raw material, thereby enhancing the stirring effect of the raw material.

[0048] Specifically, three of the first blades 220 and the second blades 320 are provided. In some other embodiments, the number of the first blades 220 and the second blades 320 can also be provided as other numbers, which is not limited here.

[0049] Specifically, the mixing drive 400 includes a motor and a rotating shaft. The motor is mounted outside the mixing drum 100, and the rotating shaft passes through the mixing drum 100 and is rotatably connected to the mixing drum 100. The rotating shaft passes through the first and second fixing portions 210 and 310, and the first and second fixing portions 210 and 310 are fixedly connected to the rotating shaft. The motor drives the rotating shaft to rotate, thereby driving the first and second fixing portions 210 and 310 to rotate about the axis of the rotating shaft, thereby driving the first and second blades 220 and 320 to rotate.

[0050] Reference Figure 5 According to some embodiments of the present application, a first through hole 223 is formed in the middle of the first blade 220 ; a second through hole 323 is formed in the middle of the second blade 320 .

[0051] It is understood that by forming the first through-hole 223 on the first blade 220, during the process of the first blade 220 stirring the raw materials, part of the raw materials can pass through the first blade 220 through the first through-hole 223, thereby reducing the resistance of the raw materials to the first blade 220 during the stirring process, thereby improving the stirring efficiency of the first blade 220, or reducing the power of the stirring driver 400. Similarly, by forming the second through-hole 323 on the second blade 320, during the process of the second blade 320 stirring the raw materials, part of the raw materials can pass through the second through-hole 323, thereby reducing the resistance of the raw materials to the second blade 320 during the stirring process, thereby improving the stirring efficiency of the second blade 320, or reducing the power of the stirring driver 400.

[0052] Reference Figure 5 According to some embodiments of the present application, the first blade 220 and the second blade 320 are staggered.

[0053] It can be understood that the first stirring blade 200 and the second stirring blade 300 are symmetrically distributed, but the first blade 220 and the second blade 320 are staggered. For example, the projections of the first blade 220 and the second blade 320 on the vertical plane do not completely overlap or do not overlap at all, so that there is a gap between the first blade 220 and the second blade 320 in the rotation direction of the first blade 220 / the second blade 320. During the stirring process of the first blade 220 and the second blade 320, the raw material can pass through the gap between the first blade 220 and the second blade 320 to reduce the resistance of the raw material to the first blade 220 and the second blade 320 during the stirring process.

[0054] Reference Figure 5 According to some embodiments of the present application, the first stirring blade 200 and the second stirring blade 300 are arranged at intervals.

[0055] It can be understood that there is a gap between the first stirring blade 200 and the second stirring blade 300, so that there is a certain gap between the first blade 220 and the second blade 320 in the horizontal direction. During the stirring process of the first blade 220 and the second blade 320, the raw material can pass through the gap between the first stirring blade 200 and the second stirring blade 300 to reduce the resistance of the raw material to the first blade 220 and the second blade 320 during the stirring process.

[0056] Specifically, the first fixing portion 210 and the second fixing portion 310 are spaced apart from each other so that the first blade 220 and the second blade 320 are spaced apart from each other.

[0057] Reference Figure 5 According to some embodiments of the present application, a first straight surface 222 is formed on the side of the first blade 220 close to the second blade 320, and a second straight surface 322 is formed on the side of the second blade 320 close to the first blade 220. The first straight surface 222 and the second straight surface 322 are inclined in directions away from each other.

[0058] It can be understood that the first straight surface 222 and the second straight surface 322 of the first blade 220 are inclined in directions away from each other to further increase the distance between the first blade 220 and the second blade 320, and further reduce the resistance of the raw materials to the first blade 220 and the second blade 320 during the stirring process.

[0059] Specifically, the first straight surface 222 is inclined in a direction away from the first fixing portion 210, and the second straight surface 322 is inclined in a direction away from the second fixing portion 310. Along the direction from the first fixing portion 210 / the second fixing portion 310 to the inner wall of the mixing barrel 100, the distance between the first straight surface 222 and the second straight surface 322 increases.

[0060] Specifically, the first blade 220 and the second blade 320 are substantially D-shaped.

[0061] Reference Figure 3 According to some embodiments of the present application, the bottom of the mixing barrel 100 is hemispherical.

[0062] It is understandable that the bottom of the mixing barrel 100 is set to be hemispherical to adapt to the rotation range of the first mixing blade 200 and the second mixing blade 300 to reduce the mixing dead angle of the first mixing blade 200 and the second mixing blade 300.

[0063] Reference Figure 2 and Figure 3According to some embodiments of the present application, the stirring device of the present application also includes a material closing plate 510 and a material closing driver 520. The material closing plate 510 is arranged below the discharge port 120, and the material closing driver 520 drives the material closing plate 510 to drive the material closing plate 510 to open or cover the discharge port 120.

[0064] It is understood that during the stirring process of the first stirring blade 200 and the second stirring blade 300, the material closing driver 520 drives the material closing plate 510 to cover the discharge port 120 to prevent the raw materials from leaking out of the discharge port 120. After the raw materials are stirred, the material closing driver 520 drives the material closing plate 510 away from the discharge port 120 to open the discharge port 120 and allow the stirred raw materials to be discharged through the discharge port 120. It should be understood that arranging the material closing plate 510 directly below the discharge port 120 can reduce the length of the channel through which the raw materials need to pass when discharged, reduce the possibility of raw materials remaining in the channel, and further reduce the stirring dead angle.

[0065] Specifically, the material closing driver 520 includes a cylinder, which drives the material closing plate 510 to move in a horizontal direction to open or cover the discharge port 120.

[0066] Specifically, the stirring device of the present application further includes two guide blocks 530 , which are arranged on both sides of the moving path of the material closing plate 510 to guide the movement of the material closing plate 510 .

[0067] Reference Figure 1 According to some embodiments of the present application, the stirring device of the present application further includes a storage barrel 600, which is arranged below the stirring barrel 100, and an upper end of the storage barrel 600 forms a feed port, which is opposite to the discharge port 120.

[0068] It is understandable that the raw materials stirred in the mixing barrel 100 can enter the storage barrel 600 through the discharge port 120 of the mixing barrel 100 and the inlet port of the storage barrel 600, and the storage barrel 600 temporarily stores the stirred raw materials.

[0069] Reference Figure 2 and Figure 3 According to some embodiments of the present application, the stirring device of the present application further includes an air blowing component 700 , which is disposed in the stirring barrel 100 , and an air outlet 710 of the air blowing component 700 faces into the stirring barrel 100 .

[0070] It can be understood that the blowing component 700 blows out compressed gas through the air outlet 710 to blow the residual raw materials in the mixing barrel 100 to the bottom of the mixing barrel 100, so that the residual raw materials can be discharged through the discharge port 120 of the mixing barrel 100 to reduce the residual raw materials in the mixing barrel 100.

[0071] Specifically, a plurality of air outlets 710 are provided to better blow out the residual raw materials in the mixing barrel 100 from the discharge port 120 .

[0072] Specifically, the air outlet 710 is set downward to facilitate blowing the raw materials to the bottom of the mixing barrel 100, and the air outlet 710 is set on the inner wall of the mixing barrel 100 to facilitate blowing the raw materials on the inner wall of the mixing barrel 100 down.

[0073] The embodiments of the present application have been described in detail above with reference to the accompanying drawings. However, the present application is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features of the embodiments can be combined with each other unless there is a conflict.
