Screening machine for Chinese medicinal materials processing

Abstract

The invention relates to a screening machine for Chinese medicinal materials processing. A casing is arranged on a frame; two ends of the casing are provided with lateral support rods; a rotating shaft is arranged on the lateral support rods at both ends of the casing; the rotating shaft passes through a sieve cylinder; the rotating shaft and the screen cylinder are connected by brackets; one endof the rotating shaft is connected to a motor through a transmission device; three sections of screen mesh are arranged on the screen cylinder, and are respectively named as screen mesh one, screen mesh two and screen mesh three in the conveying direction of the Chinese medicinal materials in the screen cylinder; the pores of the screen mesh one are smaller than the pores of the screen mesh two, and the pores of the screen mesh two are smaller than the pores of the screen mesh three; a baffle plate one is arranged on the casing and in a position corresponding to the joint of the screen mesh one and the screen mesh two; a baffle plate two is arranged on the casing and in a position corresponding to the joint of the screen mesh two and the screen mesh three; one end of the casing is providedwith a feeding inlet; the lower end of the casing is provided with three discharging ports; and a dust removing device is suspended above the casing. The screening machine is simple in structure andconvenient to operate. The sieve mesh with different pore segments is arranged on the sieve cylinder, so that the traditional Chinese medicine slices can be classified and screened, the labor intensity is reduced, and the screening efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine processing equipment, in particular to a screening machine for processing Chinese medicinal materials. Background technique [0002] Before storage and use, many traditional Chinese medicines, whether derived from animals, plants or minerals, are rough and unclean at the initial stage, and need to be processed before they can be used. Burning, frying, calcining, steaming, etc. are all methods used to process and make single Chinese medicines. The main purposes of processing and making Chinese medicines are as follows: to ensure the cleanliness of medicines. Processed medicines are clean both in appearance and medicinal use. When making processed medicines, it needs to go through processes such as washing, selection, sieving, slicing, frying (or drying), and cooking. Through these processes, impurities in the medicines are removed to ensure the quality of the medicines. The pr...

Problems solved by technology

When making processed drugs, it needs to go through processes such as washing, selecting, sieving, slicing, frying (or drying), and cooking. Through these processes, impurities in the drug are removed to ensure the quality of the drug. The processed Chinese medicinal materials need Screening and grading according to the size of the slices, and packaging separately. At present, when screening Chinese herbal medicines, it is usually screened by manual operation of the sieve frame, mainly by manpower. , unable to meet people's needs
