[0002] Tablet pressing is a process in pharmaceutical production that compresses various granular raw materials into round and shaped tablets. During the tablet pressing process, the raw materials and the tablet press are not completely flat. Tablets need to be flat before being placed in the packaging. However, the tablets produced often contain many tablet fragments. Some tablets have tiny cracks that break easily, and some have residual edges. These tablets are prone to breakage during transportation and produce pharmaceutical powder. Therefore, tablet screening is required before packaging.

[0003] In the prior art, tablets are mostly screened using an upward rotary tablet screening machine. The feed port of the upward rotary tablet screening machine is connected to the discharge port of the tablet press, and the tablets enter the upward rotary tablet screening machine for screening, and the fragments and dust brought out by the tablets are screened out. In the prior art, the tablets are directly recovered after being screened by the tablet screening machine. After the tablet screening machine is used for a long time, dust will accumulate, and the dust is not easy to be recovered and processed. The long-term accumulation of dust affects the screening quality of subsequent tablets. In addition, if the screening is only performed by the tablet screening machine, there is a situation where the drug fragments and dust are not completely screened out.
