Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tobacco powder extraction, in particular to a full-automatic tobacco powder quantitative sampling and extraction equipment and a preparation method thereof. BACKGROUND

[0002] Tobacco flavoring substances need to be extracted in advance before analysis. Since most flavoring substances have very low content, each step of extraction is critical, directly affecting the accuracy and integrity of qualitative and quantitative analysis of the analyzed substances in instrumental chemical analysis.

[0003] Tobacco extraction is a solid-liquid extraction, and the key is to prepare a sample solution. A quantitative tobacco powder needs to be weighed, an extraction solution is added, and after oscillation, the extraction solution is filtered out, and then chemical analysis can be performed. The existing analysis mainly relies on manual sampling and extraction, which is labor-intensive, low in efficiency, and prone to errors. Therefore, intelligent machinery is gradually used. For example, a tobacco extraction automatic sampling and liquid preparation experiment table with the publication number CN117091890A and the patent name of a tobacco extraction automatic sampling and liquid preparation experiment table. The table is provided with a corresponding conical bottle placement area, a measured liquid bottle placement area, a bottle cap placement area, a waste treatment area, an oscillator area, a weighing device area, a syringe area, a filter area, and a sampler area. A mechanical hand moves back and forth between each work area to move the bottle, remove the cap, add powder, add liquid, oscillate, tighten the cap, filter the liquid, and dispose of waste. In this document, each mechanism must be arranged on the same plane to facilitate smooth operation of the mechanical hand, resulting in a large floor area of the entire device or slow processing efficiency. Moreover, the previous process must be completed before the next process or additional mechanical hands and weighing devices are required, which greatly increases the cost of the overall device. Furthermore, a corresponding code scanning mechanism is required to scan the codes of the sampler, conical bottle, and measured liquid bottle for matching, which is very troublesome.

[0004] Therefore, the design of a full-automatic tobacco powder quantitative sampling and extraction equipment and a preparation method thereof through overall rational layout, improvement and connection of each mechanism can greatly reduce the floor space occupied by the device, increase the processing capacity of the device, and enable each process to be performed simultaneously to effectively improve the operation efficiency. Furthermore, only the control system is required to control each process one by one without real-time matching, which can realize full automation of the tobacco powder sampling and extraction process.

10. A fully automatic method for quantitative sampling and extraction of tobacco powder, based on the fully automatic quantitative sampling and extraction equipment of any one of claims 1 to 9, characterized in that: The following specific steps are included: S1, raw material storage: empty extraction bottles and materials to be tested are placed in order at corresponding positions of the liquid feeding device (2); S2, quantitative feeding: S21, empty bottle transmission: the extraction bottles are transmitted one by one to the rotating mechanism (202) through the transmission mechanism (201), the clamping mechanism (203) clamps and fixes the extraction bottles and rotates with the rotating mechanism (202) to the first capping mechanism (204) to unscrew the bottle caps, and at the same time, another clamping mechanism (203) rotates with the rotating mechanism (202) to face the discharge port of the transmission mechanism (201) to clamp the next extraction bottle; S22, feeding liquid: the extraction bottle passes through the capping station, the material unloading station, the liquid unloading station in sequence through the rotating mechanism (202) and returns to the capping station to unscrew the bottle cap, accurately weigh and add the material, quantitatively unload the liquid, and return the bottle cap to the cap and tighten it; S3, primary transmission: the capped extraction bottles fall through the transverse partition (101) under the action of gravity to the working area where the oscillating mixing device (3) is located, and the extraction bottles are sequentially received by the conducting device (6) and transferred to the oscillating mixing device (3); S4, oscillation extraction: the oscillation mixing device (3) can be divided into zones and batches for processing. After one zone of the oscillation mixing device (3) is filled with an extraction bottle, the oscillation mixing extraction of the material and liquid is started, and the remaining zones continue to wait for the bottles to be received; S5, secondary transmission: After the extraction is completed, the extraction bottles are clamped one by one by the conducting device (6) and placed on the capping conveying device (7). The extraction bottles are fixed by the capping conveying device (7) and the caps are unscrewed in cooperation with the conducting device (6). The capping conveying device (7) then drives the extraction bottles to move to the lower side of the liquid extractor (402); S6, filtration separation: S61, extracting liquid: after the liquid extractor (402) is moved downward and inserted into the extraction bottle, the liquid in the extraction bottle is extracted by moving its piston shaft upward; S62, filtration: after the liquid is extracted, the liquid extractor (402) moves upward and backward to be coaxially arranged with the corresponding filter (403), and the coaxially arranged liquid extractor (402) and filter (403) are moved toward each other to be plugged and fixed, and then the liquid extractor (402) drives the filter (403) to reset; S63, filtration: After the extraction is completed, the extraction bottle is reset through the capping conveying device (7), and the bottle cap is tightened by the conducting device (6) and then reset to the oscillating mixing device (3) through the conducting device (6); S64, liquid receiving bottle conveying: the liquid receiving bottle on the liquid receiving bottle support rack (11) is conveyed to the capping conveying device (7) by the liquid receiving bottle conveying device (5), and fixed by the capping conveying device (7); the bottle cap of the liquid receiving bottle is removed by the cooperation of the liquid receiving bottle conveying device (5) and the capping conveying device (7), and the bottle cap is conveyed and moved to the position directly below the liquid extractor (402) by the capping conveying device (7); S65, filtering and receiving liquid: after the liquid extractor (402) is moved downward and inserted into the liquid receiving bottle, the liquid in the liquid extractor (402) is filtered through the filter (403) by moving its piston shaft downward and then stored in the liquid receiving bottle; S7, three-time transmission: the liquid-receiving bottle after receiving the liquid is transported to the liquid-receiving bottle receiving rack (11) after the bottle cap is closed by the liquid-receiving bottle conveying device (5) and the capping conveying device (7).
