Description

An automatic sampling device for cigarette quality detection

technical field

The utility model belongs to the technical field of quality detection of tobacco products, in particular to an automatic sampling device for cigarette quality detection, which can realize automatic sampling of cigarettes in the process of cigarette quality detection.

Background technique

Cigarette head drop occurs frequently in the process of consumption, which greatly affects consumers’ recognition of cigarette products and brands, and the harm caused by head drop is increasingly criticized by consumers. On the one hand, the burning cone of cigarettes falls off, Consumers' consumption of cigarettes is interrupted. If cigarette butts are dropped to dangerous places (furniture, clothing, wilderness jungle, etc.), there may be a risk of fire (Ping An. World No Tobacco Day: Interpretation of cigarette butt fires[J]. China Fire, 2011(11): 38-42.). Cigarette processing and manufacturing companies are paying more and more attention to this phenomenon. How to improve and evaluate the cigarette end drop performance during cigarette smoking is a hot issue that cigarette companies need to solve urgently (Wang Haibin, Liu Dehu, Wu Zhaogang, etc. Analysis of cigarette burning end drop phenomenon and research [A]. Proceedings of the 2010 Symposium of the Tobacco Society of China, 2010, 285-287.)

There are many reasons for the head drop phenomenon in cigarette smoking. From the perspective of cigarette design and processing, the possible reasons are the filling state of shredded tobacco in cigarette paper, the mismatch of burning rate during combustion, and insufficient wrapping after forming soot and other reasons, and the strength of a cigarette product’s tendency to drop its head during the smoking process is the basis for improving this performance. In most cases, the evaluation of this performance depends on the sensory or Evaluation in a conscious state has a large human influence, low efficiency of data acquisition, and poor repeatability. Simultaneously, the development of a cigarette end-falling tendency detection device is also a hot issue in this technical field. The Chinese invention patent (CN 102937639 A) has designed a force applying device, and by knocking on the smoking cigarette, observe whether the cigarette falls or does not fall during the whole process of smoking and knocking. There is no description of the difference between the device’s tapping method and the actual consumer’s habit of playing ash, and the test results of this method are too simplified to give an effective and objective evaluation.

The cigarette head drop detection device involved in the Chinese utility model patent (CN 204165850 U) has made certain improvements to the problem that the device’s impact force and angle cannot be flexibly changed in the Chinese invention patent (CN 102937639 A), but there are still some deficiencies In this regard, the flicking method involved in the patent still relies on external mechanical force to knock the cigarette. It only imitates the flicking behavior on the surface, and the simple knocking action is made by mechanical parts, and does not consider the fact that the cigarette is in essence. The real force situation during the bombardment process, and how to realize fully automatic operation is not considered at the same time.

The Chinese invention patent (201710303000.2) and the Chinese invention patent (201710302981.9) respectively invented a cigarette ash drop tendency detection method based on the behavior characteristics of simulating human flicking and knocking cigarette ash. The invention defines reasonable steps and precautions for testing samples based on the two modes of flicking and knocking of the simulated human, which helps to improve the operation specification and the repeatability of test data. However, how to realize and ensure the elimination of the influence of human operation in the testing process is not involved.

Chinese invention patent (201310227468.X) is a device that detects the tendency of cigarettes to fall by means of rotation. It is characterized in that: the device includes a base, a motor, a cigarette clamping mechanism driven by the motor to rotate, and a safety shield. This invention tests the head drop phenomenon of the cigarette combustion cone by rotating the method, creating a new method of combustion cone detection, using multiple tests to obtain the statistical data of the head drop, and then obtaining the performance index of the head drop tendency when the cigarette is burning. The invention has the advantages of controllable rotation time and rotation speed, different detection intensities corresponding to different samples, wide application range, simple and convenient detection method, and short time. But this patent can only realize the detection of a single or two cigarettes at a time, and the efficiency is low.

The above patents have achieved good progress in the realization of the detection device and method of the tendency of cigarettes to fall, making it possible to detect the performance of the tendency of cigarettes to fall, but how to realize the automatic detection of batches of cigarette samples in the current invention There is still a lack of corresponding methods for detection, and there is little research on automatic sampling of cigarette samples. Basically, manual insertion is used to complete the insertion and positioning of samples, which cannot improve the work efficiency of the cigarette detection process.
