Description

Technical Field

[0001] This utility model relates to the field of high-speed rotary tablet press technology, specifically a high-speed rotary tablet press. Background Technology

[0002] A high-speed rotary tablet press, also known as a tablet compression machine, is a machine that compresses powdered and granular materials into tablets. It is a common piece of machinery in the tablet processing industry. Tablet presses are highly efficient and suitable for compressing powdered and granular materials into tablets of various shapes, such as Western medicine tablets, Chinese medicine tablets, and milk tablets. They are suitable for production and experimental use in the pharmaceutical, chemical, and health product industries.

[0003] For example, Chinese patent CN221272108U discloses a high-speed rotary tablet press, including a base and a support frame. The support frame is fixedly connected to the rear side of the outer wall of the base. A telescopic cylinder is fixedly connected to the top of the support frame, and a micro motor is fixedly connected in a ring shape to the top of the inner cavity of the support frame. A hexagonal limiting rod is fixedly connected to the power output end of the micro motor. The power output end of the telescopic cylinder passes through the top of the support frame and is fixedly connected to a moving plate. An upper punch is fixedly connected in a ring shape to the bottom of the moving plate. A sliding groove is opened at the top of the upper punch, and a push block is slidably connected to the lower side of the inner wall of the sliding groove.

After feeding, the rotary motor 3 is turned off, and the first electric push rod 81 is started to drive the lower pressing cylinders 85 and the ejector rods 862 to move downward and into the interior of the fixed grooves 2 to compress the tablets. After the tablets are compressed, the lower pressing disc 82 is driven upward by the first electric push rod 81 to move upward a certain distance. Then the second electric push rods 84 on the left and right sides are started at the same time to drive the ejector rods 862 to move downward inside the lower pressing cylinders 85 and eject the tablets attached to the lower surface of the lower pressing cylinders 85. The second electric push rod 84 drives the ejector rods 862 to move upward again and into the interior of the lower pressing cylinders 85. Then the tablets fall and are collected. By setting two first electric push rods 81, the maintenance cost of the tablet press can be reduced.

[0045] (2) After the tableting is completed, the third electric push rods 92 on the left and right sides can be started at the same time, driving no less than two push rods 94 to move upward inside no less than two pressing grooves 10 and push out the pressed tablets, so as to facilitate the removal of the pressed tablets from the inside of no less than two pressing grooves 10 and then collect them, thereby improving the processing efficiency of the tablet press.
