Rotary tablet press structure introduction PHARMA manufacturer
Starting from the structure of the forced feeding system of the rotary tablet press, the forced feeding system and the natural feeding system were compared from the working principle, and the influence of using the forced feeding system on the filling stability and stability was compared. The common analysis also discusses the rationale for the design of force-feeding systems.
The forced feeding system of the rotary tablet press (hereinafter referred to as the tablet press) is a feeding form widely used in medium and high-speed tablet presses in recent years. It is another form of filling and feeding that differs from natural feeding systems. It is considered an upgrade from natural feeding methods. This is because the working principle and structural form have changed a lot. This article will start with the structure of the force-feeding system, compare the force-feeding system with the natural feeding system in terms of working principles, and focus on analyzing the impact of the structure on tablet weight differences and common problems. so that readers can use it. People have a more systematic understanding of sex, and some discussions have been held on its design principles, hoping to inspire designers.
1 The structure of the forced feeding system of the rotary tablet press
At present, the forced feeding system of most rotary tablet presses mainly includes three parts, which are introduced as follows:
1.1 The hopper part of the rotary tablet press is mainly used for the storage of materials, and its lower part is connected with the forced feeder;
1.2 The gear motor part of the rotary tablet press is the power source of the forced feeding system. It mainly includes a three-phase/single-phase motor and a worm gear reducer. It is controlled by a frequency converter, and the output speed is adjustable. The lower part is connected to the forced feeder;
1.3 The forced feeder of the rotary tablet press is mainly used to fill the material into each intermediate die hole on the turntable, thus completing the final task of the forced feeding system, so the forced feeder is the entire forced feeding system core components.
The structure of the forced feeder of the rotary tablet press mainly uses the meshing of the gears to convert the one-way rotation of the gear motor into the reverse rotation of the two material moving impellers, and uses the material moving impellers to fill the material. Put the material cavity into the mold hole in the turntable. The shape and internal dimensions of the force feeder vary from model to model. The products of the same model are different according to the designer's design ideas, but they all have the same function and they all fill the material into the mold hole of the turntable. That is, the feeding function is completed
