Technical Field

[0002] In the process of drug manufacturing, drugs processed by the granulation device will have particles of different sizes, and drugs of different particle sizes contain different amounts of drugs. In order to facilitate patients to take the correct dosage of drugs, drug particles of different sizes need to be screened out and packaged in different specifications so that patients and doctors can take and prescribe drugs better.

[0003] After searching, a pharmaceutical preparation particle screening machine was proposed according to the Chinese utility model application number CN202321695741.7, and its invention content recorded that "through the arrangement of the screening box, feeding hole, vibration bin, screening net, vibration motor, discharge hole, drop hole, guide plate, mounting groove, mounting frame, stepping motor, rotating column, moving block, fixed column and pushing plate, the pharmaceutical preparation particles are evenly spread on the top surface of the screening net to increase its screening effect. At the same time, through the push of the pushing plate, the pharmaceutical preparation particles screened out and remaining on the surface of the screening net are pushed out of the top surface of the screening net through the drop hole to prevent larger pharmaceutical preparation particles from remaining on the top surface of the screening net and causing blockage of subsequent pharmaceutical preparation particles. Through the above operation, it is convenient to continuously screen pharmaceutical preparation particles of different sizes and ensure their integrity."
