Description

Technical Field

[0001] The utility model relates to the technical field of medicine processing, in particular to a tablet compression molding die. Background Art

[0002] Tablets are tablet-shaped preparations made from drugs, pesticides, and appropriate excipients using pharmaceutical formulation technology. Tablets consist of the active ingredient, filler, adsorbent, binder, lubricant, dispersant, wetting agent, disintegrant, flavoring, and colorant. The materials are first crushed, granulated, and dried before being pressed into tablets. Tablets are a common pharmaceutical dosage form. With the comprehensive research in traditional Chinese medicine chemistry, pharmacology, formulation, and clinical practice, the variety and quantity of traditional Chinese medicine tablets are continuously increasing, along with continuous improvements in process technology and the gradual improvement of tablet quality. In addition to standard compressed tablets and sugar-coated tablets, tablets also include microcapsules, buccal tablets, topical tablets, and effervescent tablets.

[0003] And in the document with publication number CN220681728U, a tablet pressing mold is mentioned. The mold is made by first inserting the limiting rod in the connecting piece assembly into the limiting groove to limit the position, inserting the medicine receiving rod into the forming groove to receive the medicine, and then rotating the base so that the base and the through groove are crisscrossed, so that the base is supported on the bottom plate, and then, a certain amount of powder is input into the forming groove in the forming cylinder through the medicine inlet pipe and the medicine inlet hopper for adding medicine, and then, the screw on the top plate is rotated to make the cover plate and the tablet pressing rod descend, and the tablet pressing rod descends in the forming groove until the bottom end of the tablet pressing rod contacts the powder, and cooperates with the top end of the medicine receiving rod to press it into tablets. The maximum downward pressure state of the tablet pressing rod is when the cover plate contacts the upper end surface of the forming cylinder; after the pressing is completed, the base is rotated again so that the base and the through groove overlap in the vertical plane, and the base and the structure thereon can be taken out downward from the through groove. In this way, the tablets remaining on the medicine receiving rod are taken out and compressed tablets are obtained; in this process, the tablet pressing rod will block the connection between the medicine feed tube and the molding groove. At this time, subsequent powder can be directly added to the medicine feed tube. When the tablet assembly is inserted into the molding cylinder again after taking out the tablet, the screw is rotated to move the tablet pressing rod upward, leaking out of the connection between the medicine feed tube and the molding groove. At this time, the powder will enter the molding groove. The above operation can be repeated to press the tablets for use. However, there are still certain defects that need to be optimized. The specific defects are as follows: in the process of conveying raw materials to the medicine feed rod through the medicine feed tube, the amount of medicine cannot be controlled, and the accuracy of conveying cannot be guaranteed. There is a long distance between the medicine feed tube and the medicine feed rod. The raw materials may be conveyed to the outside of the medicine feed rod. At the same time, the inside of the mold is difficult to thoroughly clean, especially the molding groove and the medicine feed tube, which affects subsequent production.

[0004] Therefore, it is particularly important to design a tablet compression molding die to change the above-mentioned technical defects and improve overall practicality. Utility Model Content
