Description

Technical Field

[0001] The invention relates to the technical field of medicinal material processing, in particular to a chopping device for processing traditional Chinese medicinal materials. Background Art

[0002] The processing of Chinese medicinal materials is a key link in the pharmaceutical process, and chopping is one of the common and crucial processing steps. Since the active ingredients of Chinese medicinal materials are usually wrapped inside the cells, chopping can increase the contact area between the medicinal materials and the solvent, making the active ingredients easier to dissolve, greatly promoting the efficiency and effect of the subsequent extraction process, and improving the utilization rate of medicinal materials.

[0003] According to the search, the Chinese patent document, with the announcement number: CN109648623B, discloses a Chinese medicine shredding device. By setting a first storage trough, a second storage trough, a baffle and a knob, the Chinese medicine tablets will enter the feeding pipe after being pushed out by the first push plate. When no further processing is required, people can turn the knob to push the baffle out of the placement trough to block the feeding pipe, so that the tablets can slide out of the slot and fall onto the conveyor belt. The tablets will fall from one end of the conveyor belt into the first storage trough of the storage box. When the tablets need to be processed, the tablets will enter the processing box from the feeding pipe for shredding, and finally be pushed into the second storage trough of the storage box by the second push plate for storage.

[0004] However, in actual use, the above-mentioned medicinal material chopping device can only chop the medicinal materials in one direction.
