[0024] Specifically, the storage box 1 has a fixed support function for the first motor 2, and when the first motor 2 is turned on, its output end can drive the transmission rod 3 to rotate, and the storage box 1 can support the rotation position of the transmission rod 3, and the transmission rod 3 can drive the top plate 5 to be lifted upward through the crank 4, and the top plate 5 has a fixed support function for the vibration frame 6, and then can drive the vibration frame 6 to slide upward inside the storage box 1, and the vibration frame 6 has a fixed support function for the support plate 8, and then when the crank 4 is separated from the top plate 5, the vibration frame 6 slides downward by its own gravity, and then the elastic force of the spring 10 drives the vibration frame 6 to vibrate up and down, thereby achieving the vibration effect of the screen 7 in the vibration frame 6, improving the effect of the preliminary screening of the catalyst particles, and improving the consistency of the subsequent perfluoropolyether siloxane membrane liquid production.
[0025] Reference Figure 2 The stirring assembly includes a stirring plate 11 , the outer wall of the stirring plate 11 is fixedly connected to the outer wall of the transmission rod 3 , and the lower surface of the storage box 1 is fixedly connected to the side plate 21 .
[0026] Specifically, when the transmission rod 3 rotates, it can synchronously drive the stirring plate 11 to rotate, and then when the stirring plate 11 rotates, it can stir the screened catalyst particles to ensure the uniformity of the catalyst. At the same time, the side plate 21 has a fixed support function for the storage box 1, which can ensure stability during stirring.
[0027] Reference Figure 1 、 Figure 3 and Figure 4 The inner wall of the storage box 1 is fixedly connected to the first feeding barrel 12; the inner wall of the side plate 21 is fixedly connected to the frame plate 13, and the upper surface of the frame plate 13 is fixedly connected to the second motor 14; the output end of the second motor 14 is fixedly connected to the first gear 15, and the outer wall of the first gear 15 is rotatably connected to the lower surface of the frame plate 13; the outer wall of the first gear 15 is meshed with the gear ring 16, and a slide groove 19 is opened inside the frame plate 13, and the outer wall of the gear ring 16 is slidably connected to the inner wall of the slide groove 19.
[0028] Specifically, the storage box 1 has a fixed supporting function for the first feeding barrel 12, and the stirred catalyst particles can be discharged through the first feeding barrel 12. The side plate 21 has a fixed supporting function for the frame plate 13, and the frame plate 13 can fix the position of the second motor 14 to ensure the stability of the second motor 14 during operation. When the second motor 14 is turned on, its output end can drive the first gear 15 to rotate, and the frame plate 13 can support the rotation position of the first gear 15. When the first gear 15 rotates, the reverse force generated by the meshing connection can drive the frame plate 13 to slide on the inner wall of the slide groove 19.

[0030] Specifically, the gear ring 16 rotates and then drives the opening and closing plate 17 to rotate through the teeth on its inner wall, and the limit column 18 can support the rotation position of the opening and closing plate 17, and then the size of the feeding port of the first feeding barrel 12 can be adjusted through the four opening and closing plates 17, and it can be opened or closed, and the discharge port of the second feeding barrel 20 corresponds vertically to the slide 19, so that quantitative discharge can be achieved by turning on the second motor 14 to control the opening and closing of the opening and closing plates 17.
[0031] Working principle: When this mechanism is needed, first pour the catalyst particles for the production of perfluoropolyether silicone membrane liquid that need to be added into the interior of the storage box 1 through the slot above the storage box 1, and then turn on the first motor 2. The output end of the first motor 2 can drive the transmission rod 3 to rotate inside the storage box 1, and then push the top plate 5 upward through the crank 4, thereby driving the vibration frame 6 to slide up and down inside the storage box 1. At the same time, when the vibration frame 6 slides downward, it can synchronously drive the support plate 8 to move, and then the support plate 8 can drive the vibration frame 6 to vibrate inside the storage box 1 through the action force between the spring 10 and the fixed box 9, thereby driving the screen 7 to vibrate, to perform preliminary screening of the catalyst particles and avoid agglomeration. After that, the catalyst particles fall into the lower half of the storage box 1 after being screened by the screen 7, and can drive the stirring plate when the transmission rod 3 rotates. 11 The catalyst particles are stirred by the first motor 2, thereby ensuring the dispersion of the catalyst particles and improving the reaction efficiency. Then the second motor 14 is turned on, and the second motor 14 can drive the first gear 15 to rotate. When the first gear 15 rotates, it drives the gear ring 16 to rotate on the inner wall of the slide groove 19 through the meshing connection, and then the gear ring 16 drives the multiple opening and closing plates 17 to rotate on the outer wall of the limiting column 18 through the internal teeth, so that the size of the discharge port between the first feed cylinder 12 and the second feed cylinder 20 can be opened or closed, thereby realizing flexible quantitative discharge of catalyst particles, that is, this mechanism can not only vibrate and stir the catalyst particles, promote catalyst dispersion and fluidity, and improve the reaction conversion rate, but also adjust the size of the discharge port to accurately control the catalyst dosage, so as to adapt to different production needs to ensure the quality of membrane liquid production.
