Structural components of high-speed rotary tablet press
Date: 2025-04-07Read: 8
The structural composition of high-speed rotary tablet press can be divided into the following core modules:
1、 Main structure of tablet press
1. Die components
It consists of three parts: upper punch, middle die, and lower punch, which are connected as a whole. 19 or 33 sets of punching dies are evenly arranged around it (with different numbers for different models). The die is embedded at the edge of the turntable, and the tail of the upper and lower punch rods is fixed on the curved guide rail. When the turntable rotates, it drives the punch rod to lift and lower along the guide rail to complete the pressing action.
2. Rotary table and guide rail system
The turntable rotates through worm gear transmission, and the mold holes are arranged in a "single row" (such as 33 holes) to alternately press the left and right pressure wheels, reducing machine vibration and energy consumption.
Some models have a dual pressure structure, with two sets of pressure wheels and feeding devices symmetrically arranged on both sides. A single rotation can continuously dispense sheets.
2、 Power and transmission system
1. Power source: The electric motor has a built-in base, which drives the worm through a V-belt to rotate the turntable.
2. Speed control device: The motor shaft is equipped with a continuously variable speed pulley, which adjusts the speed through the movement of a skateboard, ensuring stable operation and low noise.
3、 Feeding and Filling System
1. Feeding method: Adopting a flow grid or forced feeding mechanism to ensure uniform filling of the mold holes and reduce differences in sheet weight.
2. Filling control: Equipped with a filling depth adjustment mechanism, precise adjustment can be achieved through the instructions on the nameplate.
4、 Auxiliary function module
1. Powder suction device
The side of the machine base is equipped with a powder suction box, which contains a blower, powder storage room, and powder filter room. It can remove flying and falling powder to ensure smooth operation.
2. Pressure regulating mechanism
Adjust the tablet pressing pressure through the pressure wheel, and control the thickness and molding quality of the tablets according to the instructions on the label.
5、 Tablet pressing process flow
The tablet pressing process is divided into three stages: filling, pressurization (pre pressure+main pressure), and tablet release, which are completed in a continuous cycle. The dual pressure wheel design provides step-by-step pressure to enhance the density and molding stability of the tablets.
The above structure achieves high efficiency, low noise, and precise tablet pressing through modular design, meeting the diverse needs of different types of equipment.
