Description

Technical Field

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

[0002] Tablet press is a commonly used pharmaceutical equipment. It is used to make powdered drugs, granules, etc. into tablet drugs of various shapes. The working principle of tablet press is to compress the drug mixture into tablets of a certain shape and size through the action of pressure and mold. Tablet press is widely used in pharmaceutical, chemical, agricultural and other fields. Its tableting efficiency and quality play a vital role in drug manufacturing.

[0003] However, general pharmaceutical tablet presses cannot automatically push excess powder on the surface of the tableting template to the inside of the powder collection frame for quantitative collection. Due to the uneven distribution of powder, excess powder in some areas adheres to the surface of the tableting template and is then compressed and coagulated, increasing the amount of powder wasted during tableting. In addition, due to the uneven distribution of powder, it is easy for powder in some areas to fail to completely cover the tableting groove, resulting in the actual production of light weight drugs, resulting in unqualified drugs. Therefore, there is an urgent need for a pharmaceutical tablet press with a high drug qualification rate and less powder waste during tableting. Utility Model Content
