Description

Technical Field

[0001] The utility model relates to the technical field of medicine production, in particular to a press. Background Art

[0002] The starting point of pharmaceutical production is drug research and development, which involves the discovery of new drugs, preclinical trials and clinical trials to evaluate the safety and effectiveness of drugs. Sometimes, patients need to adjust the dosage of drugs according to individual differences or specific disease states, so a press is needed. After the drug is pressed, it can be more easily distributed and adjusted on demand to avoid waste and ensure the accuracy of medication. Pressing and crushing drugs is one of the basic steps in preparing a variety of drug dosage forms. By crushing the drug into appropriate particle sizes, the preparation needs of different dosage forms can be met. In the cylinder press, the cylinder is mostly an integrated structure. When the inside of the cylinder needs to be cleaned, it is necessary to clean the inside of the cylinder from the feed port. The operation is cumbersome and it is difficult to clean the inside of the cylinder.

[0003] In order to solve the above problems, the utility model patent with publication number CN213675643U discloses a cylinder press for the production of pharmaceutical intermediates. The inspection cover and the cylinder are designed as a split structure, and the sealing frame is driven by the inspection cover to leave the inside of the sealing sleeve. After the inspection cover is removed from the top of the cylinder, the inside of the cylinder is cleaned, and the operating space is larger, which makes it easier for the staff to clean the inside of the cylinder more thoroughly.

[0004] There are still some shortcomings when using the above-mentioned press. When the press applies pressure to the formed medicine, it is difficult to grind and crush the medicine at the same time, making it difficult for the pressed medicine to be completely crushed, reducing the uniformity of the crushed medicine, and thus easily resulting in the phenomenon of uneven particle sizes. Therefore, it is necessary to apply pressure to the medicine multiple times to crush the medicine, which delays the work progress, reduces work efficiency, and thus prolongs the working time when crushing the medicine.
