The wet mixing and granulating machine of spraying Teflon has multiple functions such as mixing and granulating. After the powder material is added to the mixing container, under the action of the mixing paddle and the cutter, the material is cut and stirred into a flowing state to obtain Mix well. At present, the wet mixing granulator sprayed with Teflon is widely used in the pharmaceutical, food and chemical industries. However, with the improvement of drug preparation requirements, the airtightness requirements of the equipment are getting higher and higher. Because the knife body needs to be driven by an external motor, through a series of transmission structures, it is easy to be airtight between the knife body and the granulator barrel. Poor performance affects the airtightness of the overall structure and allows external dirt to enter, which is not conducive to the production requirements of powder particles with high cleanliness. At the same time, since the knife body is driven by the motor to work, it is also necessary to prevent the powder particles in the granulator from entering The transmission connecting parts cause damage to the transmission parts. The particles after preparation will be sent out from the feeding port at the same position, but some powder particles prepared will be toxic and corrosive, and these powder particles remain at the feeding port position. It is not conducive to the processing and production of subsequent products, but due to the toxicity of the particles, it is inconvenient for the operator to clean up. At the same time, the feeding port is usually set with a mechanical structure to control the opening and closing. Some powder particles may also fall on the position of the transmission structure, which is corrosive.
