Description

Technical Field

[0001] The invention relates to the field of pharmaceutical engineering technology, and more specifically, to a high-efficiency tablet press for tablet manufacturing. Background Art

[0002] A machine that places granular or powdered materials in a die hole and presses them into tablets with a punch is called a tablet press. Tablet presses are mainly used in tablet process research in the pharmaceutical industry. Tablet presses are the pharmaceutical equipment with the longest production history in my country, and China is also the country with the earliest exports, the largest output, and the largest number of manufacturers. However, it must be mentioned that the technical content of my country's tablet presses is relatively low, and the technological innovation capability is insufficient. The gap between China's tablet presses and tablet pressing technology with developed countries abroad is still widening.

[0003] The invention with patent number CN107584798A discloses a tablet forming and pressing machine, including a support, a support platform arranged on the support, an upper mold and a lower mold, the lower mold is in the shape of a disc, which is arranged on the support platform and linked with the motor in the support platform, the upper mold includes a round table and a cylindrical upper punch arranged at the lower end of the round table, the upper punch is distributed in a circle on the round table, the support platform is in the shape of a disc, and a lower punch corresponding to the upper punch is arranged on it, and a forming hole adapted to the upper and lower punches is arranged on the lower mold, a leakage hole is arranged between the lower punches, and the leakage hole and the lower punch are evenly distributed on the same circumference, and a collection box is arranged below the support platform. The present invention cross-evenly arranges the leakage hole and the lower punch on the support platform, after the drug powder is extruded and formed in the forming hole, the lower punch moves down to its upper end flush with the surface of the support platform, and then the lower mold is rotated until the forming hole is opposite to the leakage hole, and the tablets fall into the collection box from the leakage hole, which greatly improves the production efficiency.

[0004] The invention with patent number CN118107215B discloses a roller-pressed tablet forming machine, including a frame, a vertical plate, a pressure roller and a cam, wherein the vertical plate is fixedly connected to the frame, the pressure roller is rotatably connected to the frame, the vertical plate is located on the side where the pressure roller rotates downward, and a gradually shrinking powder receiving area is formed between the upper parts of the vertical plate and the pressure roller; the pressure roller is a hollow structure, the cam is located inside the pressure roller and is fixedly connected to the frame; the pressure roller is provided with a forming hole along the circumference, a piston assembly is slidably connected in the forming hole, the inner end of the piston assembly extends into the pressure roller and forms a match with the cam; the piston assembly in the powder receiving area is limited by the outer contour line of the cam, so that the outer end surface of the piston assembly and the hole wall of the forming hole jointly form a tablet forming chamber; the outer contour line of the cam is provided with a protruding section at the lower end of the cam. The device overcomes the defect that the existing roller-pressed tablet forming machine uses two parallel arranged pressure rollers, which causes the equipment itself to be too large in size.

[0005] The above-mentioned problem with the existing tablet press is that it is not easy to accurately load multiple punching holes before tablets are pressed and formed, and the pressed medicine powder is easy to be too much or too little, which affects the thickness quality of the subsequently pressed and formed tablets. After the medicine is pressed and formed, the tablet is located in the mold and the tablet is not easy to be taken out of the mold. In addition, the tablet pressing process of most tablet presses is open or not completely sealed. The broken process causes dust to fly between the tablet pressing rooms. At the same time, during the tablet pressing process, due to poor sealing, cross contamination of tablets will occur, affecting the quality of the efficacy. Summary of the invention
