[0002] Tablet drugs are one of the most common drugs. Tablet drugs can be formed by a tablet pressing device. The working principle is to put the tablet raw materials into the mold, drive the mold to move through external forces, and the mold acts on the tablet in the mold to finally form it.

[0003] An existing solid dosage tablet pressing device is provided with a sliding template. When the formed tablet needs to be taken out, the template is pushed out from the die base through the operation of the first forward and reverse motor. A sliding support plate is provided at the lower end of the template. The support plate is separated from the template, and the second die hole on the template is exposed. The compressed tablet can be taken out. Compared with the traditional demolding process, the operation is more convenient. However, after being pushed out, the template lacks stable support. When the tablet is pushed by the push rod, it may cause the template to move, affecting the normal ejection of the tablet. For this reason, a solid dosage tablet pressing device is proposed for improvement. Utility Model Content
