Description

Technical Field

[0001] The invention relates to the technical field of traditional Chinese medicine processing, in particular to a high-efficiency crushing device for processing traditional Chinese medicine granules. Background Art

[0002] Medicinal granules are granules made from extracted and concentrated Chinese herbal medicine slices for use in clinical Chinese medicine prescriptions. Chinese medicine is usually in granular or powdered form and is small in size. The processing of Chinese herbal granules refers to a general term for a series of activities involved in processing Chinese herbal medicines into granular pills. During the processing of Chinese herbal granules, a crushing device is used for crushing. In roller crushing, the two rollers rotate relative to each other, and the material is squeezed, sheared, and to a certain extent torn by the rollers. As the rollers continue to rotate, the material is gradually broken into smaller particles.

[0003] Upon investigation, a Chinese invention patent discloses a high-efficiency crushing device for processing traditional Chinese medicine granules (publication number: CN112121914A), which includes a feed box, a crushing box and a support frame. The upper end of the inner wall of the support frame is fixedly connected to the crushing box, and the inner wall of the support frame below the crushing box is fixedly connected to a circular slide rail. The circular slide rail is fixedly connected to a discharge trough through a roller connected thereto in a rolling manner. The upper end of the inner wall of the discharge trough is fixedly connected to a filter plate, and a driving mechanism for rotating the discharge trough is provided below the discharge trough.

[0004] Although the above patent can continuously crush the Chinese medicine particles through the up and down reciprocating motion of the pressure head, and the rotation of the discharge trough and the continuous crushing of the pressure head can further improve the crushing quality, the degree of crushing of different types of Chinese medicine needs to be treated differently when preparing granules. For example, minerals need to be ultrafinely crushed to improve the dissolution rate of insoluble components, rhizomes are suitable for coarse powder, which will make the decoction sticky and difficult to filter and increase the dissolution of impurities. Medicinal materials containing volatile oils only need medium-coarse powder to avoid the reduction of particle size and the accelerated volatilization loss of components. High-oil seeds need fine powder to break the wall and release the effective ingredients. Therefore, for different medicinal materials, it is necessary to adjust the crushing of the medicinal materials by the crushing device. The crushing degree of this device is difficult to control, and it is not suitable for the processing of different types of traditional Chinese medicine. In the roller crushing process, the particle size of the output can be effectively controlled by adjusting the gap between the crushing rollers. However, in actual operation, the Chinese medicine raw materials often cannot reach the qualified crushing standards at one time when passing through the gap between the crushing rollers. For this reason, it is necessary to use a filter to filter the substandard Chinese medicine raw materials and re-crush them. Therefore, when adjusting the gap between the crushing rollers, the mesh size of the filter must be adjusted accordingly to ensure that the qualified Chinese medicine particles will not be over-crushed, and to prevent the substandard particles from passing through the filter.

[0005] Therefore, the present invention provides a high-efficiency pulverizing device for processing traditional Chinese medicine granules to solve the above problems. Summary of the Invention
