Structure of Forced Feeder of Tablet Press
The influence of the structure of the forced feeder on the filling stability
The structure of the forced feeder mainly consists of three parts, each of which is analyzed as follows:
(1) the power conversion part, its role is to reduce the motor output shaft one-way rotation into the reverse rotation of the dial impeller, that is, the relative rotation of the two impellers, the material from the hopper down to the rotary table in the die hole;
(2) the supporting part (that is, the auxiliary part), its role is to force the feeder positioning on the main body, the turntable has reliable and close positioning requirements;
(3) the material impeller and the material cavity part, which is the part of the forced feeder that has a direct impact on the filling stability of the material. In the design of the impeller and the material chamber, the design should take into account this problem: is to ensure the flow of material; Still do not change the original state of the material.
In order to ensure the fluidity of the material, the external size of the impeller and the inner size of the material cavity should be appropriate in proportion, attention should be paid to the design: first, the impeller can not be too small (relative to the material cavity), otherwise it can not play the role of sufficient material; Second, the impeller can not be too large, should make the material cavity has a certain space, in order to ensure the full flow of materials; Third, the structure and shape of the impeller itself can play a full role in the material.
