Description

Technical Field

[0001] The utility model relates to the technical field of tablet presses, in particular to a tablet press with a protective structure. Background Art

[0002] The tablet press is a machine that presses granular or powdered materials into tablets through a mold. It can meet the requirements of the pharmaceutical industry for pressing various Chinese and Western medicine preparations and other industries for pressing various similar products. During the tablet pressing process, it is very easy for debris to fall into the material, because tablet pressing is not carried out in a completely sterile environment. Once debris falls into the material, the tablet press will press it all together with the debris, which will result in impurities in the final pressed tablet.

[0003] According to a disclosed tablet press with a protective function (publication number: CN 211994345 U), in the above application, a movable plate passes through the top of the movable rod surface, both sides of the middle of the bottom of the movable plate surface are fixedly connected with tablet pressing molds, the middle of the top of the movable plate is fixedly connected with a fixing piece, the surface of the fixing piece is fixedly connected with a feed box, the feed end of the tablet pressing mold is connected to the inner cavity of the feed box, the middle of the top of the bottom plate is fixedly connected with a fixing frame, and the surface of the fixing frame is fixedly connected with a shaping mold, which can protect the material when it is tableted, so that some debris will not fall into the tablet press.

[0004] However, in actual use of the above equipment, the tablet press does not close the shaping mold during use, and it is very easy for debris to fall into the material during the tableting process. Once debris falls into the material, the tablet press will press all the debris together, which will cause impurities in the final pressed tablets. In view of this, we propose a tablet press with a protective structure. Utility Model Content
