Background
A swing granulator is a device that grinds wet powder or dry bulk material into desired granules. In the process of medicine production, the granulation of medicine is a common production flow, and when in granulation, medicine powder particles are uniformly mixed by using an adhesive, so that adhesive force is generated among the powder particles, and then the granules with a certain shape and size are formed under the action of an external machine. The swing type granulation machine is the most commonly used granulation equipment in the current pharmaceutical production.
The working principle of the swing type granulator during granulation is as follows: the seven-angle roller in the charging hopper is driven by the motor to repeatedly rotate, the part, provided with the leakage groove, of the bottom of the charging hopper is blocked by the screen mesh, the scraping plate is positioned on the screen mesh to extrude materials when the seven-angle roller rotates, and the materials are pressed to extrude the screen mesh to become a granular state. The existing swing type granulator usually directly falls into a collecting barrel from a feed opening to collect particles (such as a swing type granulator described in CN 215139651U) or directly adopts a conveying belt to convey the particles. The collecting barrel is adopted for collecting, so that materials are easy to fall off due to the swinging process of the swinging type granulator, the collecting barrel is replaced frequently, continuous granulation is affected, time and labor are wasted, a large amount of manpower is needed, and the production cost is high; if the material is directly conveyed by a conveying belt, the particles just coming out of the blanking opening still contain a certain amount of water, so that the adhesion force on the surface of the material is higher, and particularly, medicines with plant extract as raw materials are easy to cause particle bonding and pollution of the conveying belt, and the material is not easy to transfer from the conveying belt to the next process (drying process).
