Description

Technical Field

[0001] The utility model relates to the technical field of tablet detection, in particular to a device for detecting the hardness of a tablet. Background Art

[0002] Tablet hardness refers to the compressive strength of tablets after the tablet pressing process. It is one of the key indicators for evaluating the quality stability and manufacturing process of tablets, and is of great significance for ensuring the efficacy and safety of drugs. In the prior art, after the tablets are stamped and formed, the tablets enter the next process through the conveying component. During this process, the operator can take out the tablets from the conveying component by manual sampling, and then place the sampled tablets on the hardness testing instrument for quality inspection. After the quality inspection, the broken tablets are cleaned out to complete the hardness test. The degree of automation of the hardness testing process is not high, and the quality inspection efficiency is low. Therefore, a tablet hardness testing device is required to be arranged on the conveying component to realize the automation of tablet sampling, tablet hardness testing and broken tablet cleaning, so as to improve the quality inspection efficiency.
