[0030] Reference below Figures 1 to 5 The mixer according to the embodiment of the present invention is described.

[0031] like Figure 1 、 Figure 4 as well as Figure 5 As shown, the mixer according to the embodiment of the present invention includes: a frame 100, a guide assembly 200 and a first stirring mechanism 300, the frame 100 includes a frame body 110 and a lower barrel 120, the top of the frame body 110 is a top plate 111, the top plate 111 is provided with a through hole 112, and the lower barrel 120 is arranged in the frame body 110; the guide assembly 200 is hollow and fixed to the top plate 111 corresponding to the through hole 112, and the outer periphery of the lower part of the guide assembly 200 is provided with a first gear structure; the first stirring mechanism 300 includes a first driving mechanism 310, a transmission cylinder 320, an upper barrel 330 and a first stirring assembly 340, and the transmission cylinder 320 is rotatably connected to the guide assembly 340 up and down. Component 200, and at least one of the connection positions of the transmission cylinder 320 and the guide component 200 is located below the top plate 111, the first driving mechanism 310 is arranged outside the frame 110 and the output end is connected to the upper end of the transmission cylinder 320 exposed through the through hole 112, so as to drive the transmission cylinder 320 to rotate, the lower part of the transmission cylinder 320 is fixed to the lower part of the upper barrel 330, the axis of the transmission cylinder 320 and the upper barrel 330 are coaxial, the upper barrel 330 is correspondingly arranged above the lower barrel 120, the first stirring component 340 is rotatably penetrated by the upper barrel 330, and is used to stir the slurry in the lower barrel 120, and the outer periphery of the first stirring component 340 is provided with a second gear structure meshing with the first gear structure.

[0032] It can be understood that this mixer includes a frame 100, a guide assembly 200 and a first mixing mechanism 300. The frame 100 includes a frame body 110 and a lower barrel 120 arranged in the frame body 110. The top of the frame body 110 is a top plate 111 with a through hole 112; the guide assembly 200 is fixed to the top plate 111, and the guide assembly 200 is arranged corresponding to the through hole 112; the first mixing mechanism 300 includes a first driving mechanism 310, a transmission cylinder 320, an upper barrel 330 and a first mixing assembly 340. The transmission cylinder 320 is passed through the guide assembly 200. , and is rotatably connected to the guide assembly 200, at least one of the connection positions of the transmission cylinder 320 and the guide assembly 200 is located below the top plate 111, so that at least a portion of the guide assembly 200 is located below the top plate 111, and this portion will guide the transmission cylinder 320, so that the height of the guide assembly 200 above the top plate 111 can be reduced, thereby ensuring that the certain length of the guide assembly 200 can limit the deflection of the first stirring mechanism 300 and reduce the overall height of the entire device; moreover, the upper portion of the transmission cylinder 320 The end is exposed through the through hole 112 and is connected to the output end of the first driving mechanism 310. The lower part of the transmission cylinder 320 is fixed to the upper barrel 330 and is coaxial with the rotation axis of the upper barrel 330. The first stirring assembly 340 is rotatably arranged on the upper barrel 330. Therefore, the transmission cylinder 320 can drive the upper barrel 330 to rotate under the drive of the first driving mechanism 310, so that the first stirring assembly 340 can also revolve under the drive of the upper barrel 330. At the same time, since the lower part of the guide assembly 200 is provided with a first gear structure, the first stirring assembly 340 is provided with a second gear structure. The second gear structure is meshed with the first gear 220 mechanism, so while the first stirring component 340 revolves, it will also rotate under the action of the first gear structure, thereby realizing the stirring of the slurry in the lower barrel 120 by the first stirring component 340; in summary, since at least a part of the guide component 200 is located below the top plate 111, it can not only realize the guiding effect of the guide component 200 on the drive shaft 530 and reduce the radial offset of the lower part of the drive shaft 530, but also save space on the top, thereby reducing the overall height of the device and facilitating transportation.

[0033] Among them, the guide assembly 200 can be set through the through hole 112, or it can be completely set below the through hole 112. In short, at least a part of the guide assembly 200 is located below the top plate 111, and the part of the guide assembly 200 located below the top plate 111 is connected to the transmission cylinder 320, thereby reducing the swing of the first stirring mechanism 300 and reducing the height of the guide assembly 200 located on the upper part of the top plate 111.

[0034] Specifically, the first stirring assembly 340 is fixedly sleeved with a second gear 341 , and a second gear structure is provided on the outer periphery of the second gear 341 , thereby achieving meshing connection with the guide assembly 200 .

[0035] It is understood that the first bearing 410 and the second bearing 420 are respectively provided at the connection position between the transmission cylinder 320 and the guide assembly 200. The upper and lower parts of the transmission cylinder 320 are rotatably connected to the guide assembly 200 through the first bearing 410 and the second bearing 420 respectively. The second bearing 420 is located below the top plate 111. For example, Figure 5 As shown, in this embodiment, the upper part of the transmission cylinder 320 is rotatably connected to the upper part of the guide assembly 200 through the first bearing 410, and the lower part of the transmission cylinder 320 is rotatably connected to the lower part of the guide assembly 200 through the second bearing 420, and the second bearing 420 is located below the top plate 111. The first bearing 410 can be set at the position of the through hole 112, or at the upper part of the through hole 112, or even at the lower part of the through hole 112; in short, because the position of the second bearing 420 is set below the top plate 111, the transmission cylinder 320 is rotatably connected to the guide assembly 200 through two bearings, which improves the rotation stability of the transmission cylinder 320 and avoids radial displacement during the rotation of the transmission cylinder 320.

[0036] It is understood that the upper portion of the guide assembly 200 is provided with an outer flange 211 disposed near its upper end, the outer diameter of the outer flange 211 is larger than the aperture of the through hole 112, and the outer flange 211 is fixed to the upper end surface or the lower end surface of the top plate 111. For example, Figure 5 As shown, in this embodiment, the upper part of the guide assembly 200 is provided with an outer flange 211 near its upper end, and the outer diameter of the outer flange 211 is larger than the aperture of the through hole 112. Therefore, the lower end of the guide assembly 200 can be passed through the through hole 112 from top to bottom so that the outer flange 211 abuts against the upper end surface of the top plate 111, or the upper end of the guide assembly 200 can be passed through the through hole 112 from bottom to top so that the outer flange 211 abuts against the lower end surface of the top plate 111, and then the top plate 111 and the outer flange 211 are locked with the help of a locking member to achieve the fixation of the guide assembly 200 and the top plate 111.

[0037] It can be understood that the guide assembly 200 includes a guide cylinder 210 and a first gear 220. The guide cylinder 210 is fixed to the top plate 111. The first gear 220 is fixedly sleeved on the lower part of the guide cylinder 210. The first gear 220 has a first gear structure. The first bearing 410 is provided between the upper part of the transmission cylinder 320 and the upper part of the guide cylinder 210. The second bearing 420 is provided between the lower part of the transmission cylinder 320 and the first gear 220. For example, Figure 4As shown, in this embodiment, the guide assembly 200 includes a guide cylinder 210 and a first gear 220, the first bearing 410 is arranged between the upper part of the transmission cylinder 320 and the upper part of the guide cylinder 210, the second bearing 420 is arranged between the lower part of the transmission cylinder 320 and the first gear 220, and the first gear structure is formed on the outer periphery of the first gear 220, so as to play a role in driving the self-rotation of the first stirring assembly 340 in orbit.

[0038] It is understood that a third bearing is also included, located between the top of the upper barrel 330 and the guide cylinder 210. For example, in this embodiment, the lower end of the transmission cylinder 320 exposes the first gear 220 and is fixed to the bottom of the upper barrel 330, while the top of the upper barrel 330 is rotatably connected to the outer periphery of the guide cylinder 210 via the third bearing. Therefore, the top of the upper barrel 330 is sleeved within the guide cylinder 210, and the bottom of the upper barrel 330 is fixed to the bottom of the transmission cylinder 320. Therefore, the installation of the guide assembly 200 within the frame 110 does not increase the space within the frame 110, thereby achieving control over the overall volume of the blender.

[0039] It is understood that the transmission cylinder 320 has an external spline on its lower portion, and the upper barrel 330 has a corresponding spline groove. The transmission cylinder 320 drives the upper barrel 330 to rotate via the external spline. For example, in this embodiment, the lower end of the guide assembly is exposed at the lower end of the transmission cylinder 320, and the outer periphery of the lower portion of the transmission cylinder is provided with an external spline, while the upper barrel 330 is provided with a corresponding spline groove. Therefore, when the transmission cylinder 320 rotates, it can drive the upper barrel 330 to rotate via the external spline, thereby driving the first stirring assembly 340 to orbit.

[0040] It is understood that a fifth bearing group and a sixth bearing group are also included. The first stirring assembly 340 is provided with two groups and is symmetrical about the rotation axis of the upper barrel 330. The upper portion of the first stirring assembly 340 is rotatably connected to the top of the upper barrel 330 via the fifth bearing group, and the middle portion of the first stirring assembly 340 is rotatably connected to the bottom of the upper barrel 330 via the sixth bearing group. For example, in this embodiment, the first stirring assembly 340 is provided with two groups symmetrically arranged about the rotation axis of the upper barrel 330, and the upper portion of the first stirring assembly 340 is rotatably connected to the top of the upper barrel 330 via the fifth bearing group, and the middle portion of the first stirring assembly 340 is rotatably connected to the bottom of the upper barrel 330 via the sixth bearing group. This makes relative rotation between the first stirring assembly 340 and the upper barrel 330 relatively easy, and the symmetrical arrangement of the two groups can increase stirring uniformity.

[0041] It is understood that the first stirring mechanism 300 includes a first transmission mechanism 350, which is connected between the first driving mechanism 310 and the transmission cylinder 320 and is located on the top of the top plate 111. The first driving mechanism 310 is provided on the side of the frame 110. For example, Figures 2 to 5As shown, in this embodiment, the first stirring mechanism 300 includes a first transmission mechanism 350 located on the top of the top plate 111, and the first driving mechanism 310 is provided on one side of the frame 110. The output end of the first driving mechanism 310 is connected to the transmission cylinder 320 through the first transmission mechanism 350. Specifically, the first transmission mechanism 350 is a transmission belt mechanism. Therefore, by arranging the first driving mechanism 310 on the side of the frame 110, the height of the first driving mechanism 310 is avoided from increasing the overall height of the mixer, and the first transmission mechanism 350 can realize the transmission of the drive.

[0042] Specifically, a reducer is provided between the first transmission mechanism 350 and the first driving mechanism 310 and is also provided on one side of the frame 110 , thereby further reducing the space occupied by other components on the upper portion of the top plate 111 and reducing the overall height of the mixer.

[0043] It is understandable that a second stirring mechanism 500 is also included, and the second stirring mechanism 500 includes a second driving mechanism 510, a second transmission mechanism 520, a transmission shaft 530 and a second stirring component 540. The second driving mechanism 510 is arranged on the side of the frame 110, and the transmission shaft 530 is rotatably installed in the transmission cylinder 320. The upper end of the transmission shaft 530 is exposed from the transmission cylinder 320 and is connected to the output end of the second driving mechanism 510 through the second transmission mechanism 520. The second stirring component 540 is rotatably installed in the upper barrel 330 and is in transmission connection with the transmission shaft 530. The second stirring component 540 is used to stir the slurry. For example, Figures 2 to 5 As shown, in this embodiment, the second stirring mechanism 500 includes a second driving mechanism 510, a second transmission mechanism 520, a transmission shaft 530, and a second stirring assembly 540. The transmission shaft 530 is rotatably disposed within the transmission cylinder 320. The upper end of the transmission shaft 530 protrudes through the through-hole 112 and is in driving connection with the second transmission mechanism 520. The second transmission mechanism 520 is connected to the output end of the second driving mechanism 510. The transmission shaft 530 is in driving connection with the second stirring assembly 540. The second stirring assembly 540 is rotatably disposed within the upper barrel 330. Therefore, driven by the second driving mechanism 510, the second transmission mechanism 520 can drive the second stirring assembly 540 to rotate via the transmission shaft 530. The second stirring assembly 540 can also revolve under the drive of the upper barrel 330, thereby enabling the second stirring assembly 540 to stir the slurry within the lower barrel 120. Specifically, the second stirring assembly 540 rotates at a faster speed than the first stirring assembly 340. The fast and slow stirring can improve the dispersion and stirring effects. The second driving mechanism 510 is disposed on the side of the frame 110 , which can also reduce the space occupied by the top plate 111 .

[0044] It is understood that the second stirring mechanism 500 further includes a third transmission mechanism 550, and the third transmission mechanism 550 connects the transmission shaft 530 and the second stirring assembly 540. Figure 4 As shown, in this embodiment, the second stirring mechanism 500 further includes a third transmission mechanism 550 connected to the transmission shaft 530 and the second stirring assembly 540, thereby realizing transmission between the transmission shaft 530 and the second stirring assembly 540. Specifically, two groups of second stirring assemblies 540 are provided, so each group of second stirring assemblies 540 realizes transmission between the transmission shaft 530 via a group of third transmission mechanisms 550. The third transmission mechanism 550 is a synchronous belt mechanism.

[0045] It is understood that the seventh bearing 460 and the eighth bearing 470 are also included. The lower end of the transmission shaft is exposed from the lower end of the transmission cylinder. The seventh bearing 460 is arranged between the upper end of the transmission shaft 530 and the upper end of the transmission cylinder 320. The eighth bearing 470 is arranged between the lower end of the transmission shaft 530 and the lower end of the transmission cylinder 320. For example, Figure 5 As shown, in this embodiment, the upper end of the transmission shaft 530 is rotatably connected to the upper end of the transmission cylinder 320 through the seventh bearing 460, and the lower end of the transmission shaft 530 is rotatably connected to the lower end of the transmission cylinder 320 through the eighth bearing 470, so that the relative rotation between the transmission shaft 530 and the transmission cylinder 320 can be achieved more easily.

[0046] 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.
