[0025] The granulating blade structure of a wet granulator is described with reference to Figures 2 to 4 The granulating blade structure of a wet granulator according to a preferred embodiment of the present application is provided on a wet granulator. Specifically, as shown in Figure 2 The wet granulator includes a barrel 10 and a rotary driving device 20. The barrel 10 has a granulating cavity 101. A stirring paddle 1011 is rotatably installed at the center of the bottom wall of the granulating cavity 101. The rotary shaft of the rotary driving device 20 is connected to the granulating blade structure of the wet granulator through a coupling.
[0026] Specifically, as shown in Figure 3 and Figure 4As shown, the granulating blade structure of the wet granulator comprises a first shaft body 30 and a second shaft body 40. One end of the first shaft body 30 is fixedly connected with the rotating shaft of the rotating drive device 20, the other end of the first shaft body 30 extends into the granulating cavity 101, and the end of the first shaft body 30 away from the rotating shaft of the rotating drive device 20 is provided with a U-shaped groove 301, one end of the second shaft body 40 extends into the U-shaped groove 301 and is detachably connected with the first shaft body 30, and the other end of the second shaft body 40 is connected with a plurality of blades 401. In the embodiment of the present application, the blades 401 are welded with the second shaft body 40.
[0027] It should be noted that before granulation, the granulating cavity 101 needs to be cleaned, at which time the blades 401 need to be removed. In the embodiment of the present application, only the second shaft body 40 needs to be rotated by a predetermined distance, and the slot opening of the U-shaped groove 301 needs to be directed towards the cavity opening of the granulating cavity 101, then the second shaft body 40 is separated from the first shaft body 30, and the second shaft body 40 can be taken out from the U-shaped groove 301 by hand from bottom to top, realizing the separation of the blades 401 and the barrel 10. It can be seen that, compared with the prior art, when the blades are removed, the blades are sequentially taken out from right to left, and the palm is easy to contact and be scratched by the stirring paddle 1011 in the process of moving towards the central axis of the granulating cavity 101. The embodiment of the present application has the advantages of taking the shaft body from bottom to top, which helps to reduce the risk of being scratched.
[0028] Further, in order to realize the detachable separation of the second shaft body 40 and the first shaft body 30, as shown in Figure 3 and Figure 4 both sides of the U-shaped groove 301 are provided with a first through hole 3011, one end of the second shaft body 40 extending into the U-shaped groove 301 is provided with a second through hole 402, and the granulating blade structure of the wet granulator further comprises a plug pin 50, the plug pin 50 penetrating the first through hole 3011 and the second through hole 402.
[0029] It should be noted that when the plug pin 50 is inserted into the first through hole 3011 and the second through hole 402, the second shaft body 40 is fixed in the U-shaped groove 301, and when the first shaft body 30 rotates, the second shaft body 40 rotates with it and drives each blade 401 to rotate; when the plug pin 50 is pulled out of the first through hole 3011 and the second through hole 402, the second shaft body 40 can freely move along the U-shaped groove 301 and can be taken out.
[0030] Further, in order to avoid the plug pin 50 from being pulled out of the first through hole 3011 and the second through hole 402 when the first shaft body 30 rotates, as shown inFigure 3 and Figure 4 As shown in Figs. 1 and 2, the granulating blade structure of the wet granulator further comprises a sleeve ring 60, which is slidably sleeved on the first shaft body 30. When the sleeve ring 60 slides, the inner wall of the sleeve ring 60 abuts against or separates from the plug 50.
[0031] It should be noted that, in the daily granulation process, the sleeve ring 60 is sleeved on the first shaft body 30 and closes the first through hole 3011 to prevent the plug 50 from being pulled out of the first through hole 3011. When the second shaft body 40 needs to be disassembled, the disassembling personnel only needs to slide the sleeve ring 60 and make the inner wall of the sleeve ring 60 no longer close the first through hole 3011, and then the plug 50 can be taken out. After the plug 50 is taken out, the second shaft body 40 can be separated from the U-shaped groove 301.
[0032] Further, as shown in Figs. 1 and 2, when the first shaft body 30 rotates, the sleeve ring 60 slides and does not close the first through hole 3011, and both ends of the plug 50 are embedded with a first magnet 501, and the inner wall of the sleeve ring 60 has a magnetic coating 601. Figure 3 and Figure 4 It should be noted that, when the plug 50 is inserted into the first through hole 3011 and the sleeve ring 60 closes the first through hole 3011, the first magnet 501 and the magnetic coating 601 are attracted to each other, thereby fixing the position of the sleeve ring 60.
[0033] Further, as shown in Figs. 1 and 2, when the second shaft body 40 is placed in the U-shaped groove 301, the first through hole 3011 is directly opposite to the second through hole 402. As shown in Figs. 1 and 2, the bottom wall of the U-shaped groove 301 has a protruding portion 3012, and the end wall of the second shaft body 40 extending into the U-shaped groove 301 has a groove 403. When the protruding portion 3012 extends into the groove 403, the first through hole 3011 is directly opposite to the second through hole 402. Figure 4 Further, as shown in Figs. 1 and 2, in order to facilitate the disassembling personnel to hold the second shaft body 40, the end of the second shaft body 40 away from the first shaft body 30 has a holding end 404, the end face of the holding end 404 is spaced apart from the blade 401 by a predetermined distance, and the holding end 404 is a light axis surface.
[0034] Figure 3 In summary, the granulating blade structure of the wet granulator according to the embodiments of the present application is illustrated, which provides the advantages of taking the shaft body from bottom to top, helping to reduce the risk of being scratched, and the like.
[0035] In summary, the granulating blade structure of the wet granulator according to the embodiments of the present application is illustrated, which provides the advantages of taking the shaft body from bottom to top, helping to reduce the risk of being scratched, and the like.
