Description

Technical Field

[0001] The utility model relates to the technical field of medicine granulating devices, in particular to a medicine granulating machine. Background Art

[0002] The processing of drug raw materials is an important step in the drug manufacturing industry. When making medicines, the drug raw materials need to be granulated. Only after the drug granulation process can the drug particles be used in tableting, capsule filling and other drug processing and molding processes.

[0003] In actual production and processing, pharmaceutical granulators are widely used in granulation process. During the granulation process, the pharmaceutical granulator needs to grind the drug to make the block or tablet drug into fine powder. When the pharmaceutical granulator grinds the drug into fine powder, water mist will be sprayed out of the pharmaceutical granulator at the same time. The water mist in the machine will mix with the powdered drug and agglomerate it to form drug particles. However, the drug particles are still relatively moist at this time. If the drug particles are collected, the drug particles are prone to stick to each other, which makes the drug granulation effect poor.

[0004] Based on this, in order to prevent drug particles from sticking to each other and improve the effect of drug granulation, a drug granulator is now proposed. Utility Model Content

DETAILED DESCRIPTION

[0068] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0069] Embodiment 1

[0070] In the prior art, the drug needs to be ground to make the block or tablet drug into fine powder. When the drug granulator grinds the drug into fine powder, water mist will be sprayed out of the drug granulator at the same time. The water mist in the machine will mix with the powdered drug and agglomerate it to form drug particles. However, the drug particles are still relatively wet at this time. If the drug particles are collected, the drug particles are prone to stick to each other, resulting in a poor effect of drug granulation.

[0071] Based on this, in order to solve the above technical problems, the following technical solutions are now adopted, as follows:

[0075] The two inclined portions 101 can prevent the drug from accumulating at the bottom of the inner cavity of the granulation box 10;

[0076] A top cover 20, which is fixedly mounted at the top opening of the granulating box 10;

[0077] A feed slot 30, the feed slot 30 is fixedly mounted at the top center of the top cover 20;

[0078] Wherein, the medicine can be put into the inner cavity of the granulation box 10 through the feed slot 30;

[0079] A first roller 40, which is rotatably mounted on one side of the inner cavity of the granulating box 10;

[0080] A second roller 90, which is rotatably mounted on the other side of the inner cavity of the granulating box 10;

[0081] The first roller 40 and the second roller 90 are symmetrically arranged, and the first roller 40 is tangent to the side wall of the second roller 90;

At this time, the surface of the drug particles is moist. Under the heating action of the far-infrared heating plate 180, the drug particles can be dried and dehumidified, and the drug particles can be formed. When the drug particles fall to the bottom of the inner cavity of the granulating box 10, they can be vibrated synchronously under the vibration action of the two vibration motors 170.

[0095] In this embodiment, when the wet drug particles are dried, dehumidified, heated, and formed by the far-infrared heating plate 180, the sticking phenomenon between the drug particles can be effectively avoided, thereby improving the effect of drug granulation;

[0096] At the same time, due to the continuous vibration of the machine body and the screening effect of a plurality of medicine outlet sieve holes 102, the medicine particles can be made more uniform.
