[0002] The powder of adenosinecobalamin capsules is a mixture of adenosinecobalamin active ingredients, cellulose, corn starch and other raw materials. Cellulose and corn starch are prone to adhesion under a certain air humidity.

[0022] The beneficial effects of the present invention are:

[0023] 1. The present invention designs a set of exciting mechanisms to continuously vibrate the raw materials of adenosine cobaltamine capsule powder to achieve the breakage of the raw materials of adenosine cobaltamine capsule powder, and at the same time, a mixing mechanism driven by airflow and electric field is set to mix the raw materials of adenosine cobaltamine capsule powder. By adjusting the driving force of airflow and electric field, only the tiny particles produced by crushing can be mixed and driven, while large agglomerates can continue to be vibrated, thereby achieving sufficient mixing of small particles; at the same time, this scheme utilizes the dual drive of large particles being driven more by airflow and small particles being driven more by electric field, ensuring the synchronous movement of large particles and small particles, ensuring the uniform mixing of large and small particles, so that the content uniformity is improved, and the RSD can be controlled below 0.5%; in addition, the airflow mechanism can adaptively cool each electric field generating element.

[0024] 2. The adenosinecobalamin capsule powder raw material is finally collected by a scraper. Compared with air flow blowing collection and vibration collection, it is not easy to cause secondary stratification of adenosinecobalamin capsule powder raw materials of different diameters and weights, thereby ensuring the mixing effect of the adenosinecobalamin capsule powder raw material.

[0025] 3. The interception mechanism can collect the powder falling from the vibration net through the interception bucket and guide it upward.

[0026] 4. The flow bulge guides the airflow and blows the particles upward for a second time to prevent leakage and waste of the raw material powder of adenosine cobalamin capsule powder.

[0027] 5. The first floating ring is fixed by clamping and connected to the device housing through an insulating gasket, which replaces the clamping or bonding fixation of the first floating ring relative to the device housing, expands the material selection range of the first floating ring, and compared with bonding fixation, it has a longer service life and is more convenient to replace.

[0028] 6. The excitation frame is fixed up and down, which makes the first floating ring and the grading screen easy to install and maintain. In addition, the first conductive ring can improve the conductive efficiency and reduce the heat generation of the excitation frame in the working state due to its own resistance.

[0029] 7. The feed pipe is fed through a spiral stirring paddle, which can increase the air flow resistance in the feed pipe and prevent the air flow from blowing out of the feed pipe.

[0030] 8. The extension tube can ensure that the adenosine cobalamin capsule powder raw material falls into the center of the vibration net, and the adenosine cobalamin capsule powder raw material is placed on the edge of the vibration net with a relatively small vibration amplitude. At the same time, the extension tube is tangent to the blowing direction of the airflow, which can reduce the interference of the airflow on the discharge.

[0031] 9. The rubber support block can not only achieve sealing, but also ensure stable elastic support for the mixing frame; the counterweight block structure can reduce the arm length of the exciting torque, reduce the load of the exciting connecting rod, and improve the life of the equipment by transmitting the exciting torque.

[0032] 10. The guide plate can apply electric charge to the adenosine cobalamin capsule powder raw material again, and generate a relatively short electrostatic field between the guide plate and the aggregate frame, thereby increasing the movement speed of the adenosine cobalamin capsule powder raw material particles. At the same time, the guide plate can generate a certain turbulence between the guide plates by increasing the flow resistance, and the turbulence can improve the mixing effect and rate of the adenosine cobalamin capsule powder raw material.

[0033] 11. Compared with the straight-out structure, the discharge pipe with a spiral stirring paddle has a larger air flow resistance, which can prevent the secondary stratification of the adenosine cobalamin capsule powder raw material particles caused by the airflow blowing drive due to different flow resistance. At the same time, the combination of the adenosine cobalamin capsule powder raw materials can be completed by squeezing and mixing the spiral stirring paddle at the same time, thereby reducing the possibility of secondary stratification of the adenosine cobalamin capsule powder raw materials during transportation and filling.

Because the flow cross-sectional area becomes smaller, the flow velocity will increase, and the flow resistance will also increase synchronously. The large and small particles of raw materials will be in the guide plate due to the disturbance caused by the flow resistance. The plates 38 are fully mixed and move together. At the same time, because the cross-sectional area of ​​large particles is larger, they are driven by the high-velocity airflow at a faster rate. At the same time, the guide plate 38 connected to the negative electrode through the second conductive ring 37 will form a strong driving electric field with the aggregate frame 42. The driving electric field will drive the small particles to move quickly. By adjusting the appropriate exhaust speed and electric field strength, large particles and small particles can be moved to the surface of the aggregate frame 42 at the same moving speed after mixing, and removed by the scraper 47. The scraper 47 ensures that the material is at a low speed and low kinetic energy during material separation, and no secondary stratification of large particles and small particles will occur due to the secondary relative movement.
