Description

A cigarette automatic ignition and burning line detection device for cigarette quality inspection

Technical Field

The invention belongs to the technical field of tobacco product quality detection, and specifically relates to a cigarette automatic ignition and burning line detection device for cigarette quality detection. The device can realize the detection of cigarette automatic ignition and burning line in the process of cigarette quality detection.

Background technique

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

There are many reasons for the phenomenon of cigarette head falling during smoking. From the perspective of cigarette design and processing, the possible reasons are the filling state of tobacco in cigarette paper, the mismatch of burning rate during combustion, and the insufficient wrapping after the ash is formed. The strength of the tendency of a cigarette product to fall during smoking is the basis for improving this performance. In most cases, the evaluation of this performance relies on the evaluation of the evaluator in a sensory or conscious state, which has a large human influence, low efficiency in obtaining data, and poor repeatability. At the same time, the development of a device for detecting the tendency of cigarette head falling is also a hot issue in this technical field. The Chinese invention patent (CN 102937639 A) designs a force-applying device, which knocks on the cigarette being smoked, and observes whether the cigarette falls or not during the entire smoking and knocking process. There is no description of the difference between the knocking method used by the device and the actual consumer's ash-flicking habits, and the test result judgment of this method is too simplified, and an effective and objective evaluation cannot be given.

The cigarette end detection device involved in the Chinese utility model patent (CN 204165850 U) has made certain improvements to the problem that the impact force and angle of the device in the Chinese invention patent (CN 102937639 A) cannot be flexibly changed, but there are still certain shortcomings. The impact method involved in the patent still relies on mechanical external force to knock on the cigarette, which only imitates the surface impact behavior and makes a simple knocking action by mechanical parts. It does not consider the actual force situation of the cigarette during the impact process, and also does not consider how to achieve fully automatic operation.

The two invention patents, Chinese invention patent (201710303000.2) and Chinese invention patent (201710302981.9), respectively invented a method for detecting the tendency of cigarette ash to fall based on the characteristics of the ash falling behavior of simulating human flicking and knocking. The invention defines the reasonable steps and precautions for testing samples based on the two modes of simulating human flicking and knocking, which helps to improve the repeatability of operating specifications and test data. However, how to achieve and ensure the elimination of the influence of human operation during the test process is not involved.

The Chinese invention patent (201310227468.X) is a device for detecting the tendency of cigarettes to fall off by rotating, characterized in that the device includes a base, a motor, a cigarette clamping mechanism driven to rotate by the motor, and a safety shield. The invention tests the falling phenomenon of cigarette burning cones by rotating, creating a new method for burning cone detection, using multiple tests to obtain statistical data on falling cigarettes, and then obtaining performance indicators of the tendency of cigarettes to fall off when burning. The advantages of the invention are: the rotation time and number of revolutions are controllable, different detection intensities can be used for different samples, and the application range is wide; the detection method is simple and convenient, and the time is short.

The above patents have made great progress in the realization of the device and method for detecting the cigarette falling tendency performance, making the detection of the cigarette falling tendency performance possible, but none of them involve the automatic ignition of cigarettes and the detection of the burning line. The above inventions all require manual ignition of cigarettes, which not only causes human errors, but also greatly reduces the work efficiency of the detection process. At the same time, there is currently a lack of devices and methods for detecting the burning line of cigarettes during the cigarette falling tendency performance test.
