AI Technical Summary
In existing drug particle preparation equipment, the good fracture resistance of the material during dry preparation makes it difficult to form particles. After passing through the mesh plate, the material is set in strips and requires secondary processing.
A rotary cutter-assisted cutting mechanism is adopted. The rotary cutter is sleeved on the drive shaft of the compaction mechanism and rotates synchronously with the compaction mechanism to cut the material passing through the mesh plate into granular particles. The granulated drug is then pushed to the discharge hopper by the synchronously pushing discharge mechanism.
This technology enables materials to be directly formed into granules after passing through the mesh, eliminating the need for secondary processing, simplifying the granulation process, and improving production efficiency and convenience.

Technical Field
[0001] This utility model relates to the field of pharmaceutical equipment technology, specifically to a drug particle preparation device. Background Technology
[0002] Drugs are substances used to prevent, treat, and diagnose diseases. Theoretically, drugs refer to any chemical substance that can affect the physiological functions of organs and cellular metabolic activities. Currently, drug preparation requires various types of equipment, including drug particle preparation equipment.
[0003] The existing drug granulation equipment still has the following problems when in use: When the drug granulation equipment adopts the dry method, the dry granulation machine has high requirements for the physical properties of the material. If the material has good fracture resistance, it may lead to difficulties in granulation. The material is still set in strips after passing through the screen and cannot form granules. It often needs to be processed again, which is inconvenient. Utility Model Content

The outer blade of the rotating blade 211 can cut the falling drug material. Even if the material has good fracture resistance, the material will still be granulated by the rotating blade 211 after passing through the screen plate 24, thus forming granular particles.

The transmission method is a reduction transmission. At this time, the drug raw material to be granulated can be fed into the second processing shell 22 through the feeding guide hopper 23.
