Description

Technical Field

[0001] The utility model relates to the technical field of medicine processing, in particular to a tablet forming device. Background Art

[0002] Tablets are solid preparations in the form of flakes or special-shaped flakes formed by uniformly mixing drugs and excipients and then compressing them. Tablets are mainly oral ordinary tablets, but also include lozenges, sublingual tablets, buccal patches, chewable tablets or controlled-release tablets and enteric-coated tablets. Tablets have the characteristics of stable quality, accurate dosage, low cost and selling price, and convenient transportation, storage, carrying and application.

[0003] In the process of tablet production, the drug and excipients are usually mixed evenly and then injected into the tablet forming device. The tablet forming device then extrude the granules or powdered materials through a punch head to obtain the required tablets. The extruded tablets are then ejected through a lifting device and finally taken out by staff.

[0004] During use, the existing tablet forming device requires workers to take out the extruded tablets. This operation mode imposes a heavy workload on workers and often causes mechanical injuries. Some tablet forming devices use a driving device to drive the punch head to extrude granular or powdered materials, and after the extruded tablets are ejected by the lifting device, an additional driving device is used to drive the push plate to move, thereby pushing out the prepared tablets. Although this increases safety and reduces the workload of workers, it also makes the internal structure of the tablet forming device more complicated and the cost is relatively high. For this reason, we propose a tablet forming device. Utility Model Content
