Description

TECHNICAL FIELD

[0001] The utility model relates to tablet press technical field, especially a kind of instantaneous cooling press roller type tablet press. BACKGROUND

[0002] The processing method of powder coating is to mix powders of each component, then heat and melt the mixed powders, and then promote the uniformity of the mixture between each component. The melted mixture is then extruded through an extruder. The material coming out of the extruder is pressed into tablets by a tablet press (usually a press roller type tablet press). The tablet-shaped product coming out of the tablet press is ground after subsequent cooling, and then powder coating is formed.

[0003] During the process of extruding into tablets, the material needs to be cooled while being extruded. The current method is to pass cooling water into the press roller, which cools the roller wall of the press roller to achieve the cooling effect of the material. In order to ensure the flowability of the cooling water, a spiral stirring blade is provided in the press roller to assist the delivery of the cooling water. However, this cooling method of the press roller has drawbacks: the cooling water will accumulate at the bottom under the action of gravity, and the cooling effect is concentrated at the bottom. However, the position where the two press rollers exert pressure is at the opposite sides. In the case of insufficient water, the cooling effect on the sides is poor. If there is too much cooling water, it will cause excessive burden on the press roller, and the updating and circulation of the cooling water is slow, the temperature of the water in the roller cannot be kept low in real time, and the overall cooling effect is not good.

[0004] Since the extrusion cooling process is usually instantaneous, not a long-term cooling process, as described above, due to the uneven distribution of cooling water in the prior art, the water is concentrated at the bottom, and the water circulation is slow when there is too much water, resulting in poor cooling capacity and poor instantaneous cooling effect, which needs to be improved.

[0005] In view of the above-mentioned deficiencies in actual production and implementation, the present application is modified and improved, and the spirit and concept of seeking good are pursued, and the assistance of professional knowledge and experience is provided, as well as the cleverness and trial of many parties, a kind of instantaneous cooling press roller type tablet press is provided to solve the problem of poor instantaneous cooling effect of the current press roller type tablet press.
