Description

Technical Field

[0001] The utility model relates to the technical field of medicinal material screening, in particular to an automatic medicinal material screening device. Background Art

[0002] In the field of Chinese medicinal materials processing, the screening of medicinal materials is a crucial link, which involves the particle size control, quality classification and the smooth progress of subsequent processing procedures. Traditional medicinal materials screening equipment mainly uses linear screening machines for screening.

[0003] As a common screening equipment, the linear screening machine can realize the screening function of medicinal materials, but it still has defects when used, that is, it can only screen one kind of medicinal material. If different kinds of medicinal materials enter the screening machine at the same time, it is easy to mix due to differences in physical properties (such as density, shape, particle size, etc.), resulting in inaccurate screening results. Therefore, when the linear screening machine is screening, it is usually necessary to wait for the previous batch of medicinal materials to be completely screened before the next batch of medicinal materials can be screened. This continuous working mode makes the entire screening process inefficient, especially during the peak period of medicinal material processing. This low efficiency will further increase production pressure and affect the overall progress of medicinal material processing. In order to solve the above problems, a possible solution is to increase the number of screening machines, that is, to purchase multiple screening machines at the same time. However, although this method can improve the screening efficiency to a certain extent, it is accompanied by high equipment purchase costs, maintenance costs and space occupancy costs. Increased costs, it is not practical for many Chinese medicinal material processing companies. Utility Model Content
