Description

TECHNICAL FIELD

[0001] The application relates to the field of traditional Chinese medicine processing equipment, in particular to a decoction piece subpackaging machine. BACKGROUND

[0002] Traditional Chinese medicine decoction pieces are traditional Chinese medicines that are directly used in clinical treatment of traditional Chinese medicine after being processed according to the theory of traditional Chinese medicine and processing methods of traditional Chinese medicine. The concept shows that there is no absolute boundary between traditional Chinese medicinal materials and traditional Chinese medicine decoction pieces, and the traditional Chinese medicine decoction pieces include part of traditional Chinese medicine slices processed in the producing area, original medicinal material decoction pieces and decoction pieces processed by cutting and processing. Usually, the traditional Chinese medicine decoction pieces need to be packaged after processing, so as to be transported and sold.

[0003] Common packaging methods of traditional Chinese medicine decoction pieces mainly include bagging and box packaging, and packaging operations are usually carried out by mechanical automatic filling, manual filling and semi-automatic operation of mechanical and manual cooperation, and automatic / semi-automatic subpackaging equipment is also used in large-scale pharmaceutical factories to subpackage traditional Chinese medicine decoction pieces. For example, a small-packaged traditional Chinese medicine decoction piece automatic packaging machine disclosed in Chinese Patent No. CN102887235B comprises a mechanical part and a control part, the mechanical part comprises a feeding groove, a distribution disc, a pre-storage hopper, a metering hopper, a collection hopper and a discharge hopper, the feeding groove is located at the top, the distribution disc is below the feeding groove, the distribution disc is connected with the pre-storage hopper, the pre-storage hopper is below the metering hopper, the collection hopper and the discharge hopper are sequentially connected below the metering hopper, the mechanical part is controlled by the control part, and feeding, distribution, metering and discharging are carried out according to the setting. The automatic metering, subpackaging, accurate metering, high automation level, clean metering and subpackaging process, less pollution, high work efficiency and low production cost can be realized.

[0004] For another example, a traditional Chinese medicine decoction piece automatic weighing and subpackaging machine disclosed in Chinese Patent Application No. CN109866967A comprises a rack, a feeding hopper support installed on the top of the rack, a feeding hopper installed on the feeding hopper support, a main vibration disc installed and hung directly below the feeding hopper, a plurality of linear vibration discs distributed in a circular array with the center of the main vibration disc as the center of the circle and installed on the rack, a storage hopper installed below the end of each linear vibration disc, a weighing hopper installed directly below the storage hopper, a combined material receiving groove installed directly below the weighing hopper and arranged obliquely inward, a discharge hopper installed below the combined material receiving groove and a distribution hopper installed directly below the discharge hopper. The traditional Chinese medicine decoction piece automatic weighing and subpackaging machine has simple structure, ingenious design and high automation degree, and can simultaneously carry out automatic accurate weighing, combined weighing and distribution packaging of traditional Chinese medicine decoction pieces with the same weight or different weights.

[0005] In the actual production and processing of traditional Chinese medicine decoction pieces, the above-mentioned automatic packaging machines and automatic weighing and dispensing machines can only achieve batch packaging of traditional Chinese medicine decoction pieces, i.e. a certain amount of traditional Chinese medicine decoction pieces is directly poured into a packaging bag or a packaging box for dispensing. For a gift box type packaging method which requires column-by-column and / or row-by-row placement and stacking from bottom to top, the traditional automatic packaging machines and automatic weighing and dispensing machines are not applicable, and the above-mentioned gift box type packaging method of traditional Chinese medicine decoction pieces is basically carried out by manual filling. The manual filling method for packaging operation not only has high labor intensity and low efficiency, but also causes pollution to irregular traditional Chinese medicine decoction pieces to some extent during the operation of the operator, i.e. the traditional packaging method / mechanical equipment is actually difficult to meet the production demand of the gift box type packaging method.
