Description

A kind of cigarette falls head detection rotating disc type cigarette device for inserting and placing
Technical field
The invention belongs to tobacco product technical field of quality detection, and in particular to one kind falls head detection turntable suitable for cigarette Formula cigarette device for inserting and placing, realizes the cigarette placement operation in head tendency detection process is fallen to cigarette.
Background technology
Cigarette occurs often in process of consumption decline head phenomenon, accreditation of the extreme influence consumer to cigarette product and brand Degree, and fall the harm caused by head and also increasingly denounced by consumer, one side cigarette combustion cone comes off, and has interrupted consumption Consumption of the person to cigarette, if the cigarette butt that drops is to danger position(Furniture, clothing, wilderness jungle etc.), may there is the wind that fire occurs Danger(The safety World No Smoking Days:Understand cigarette butt fire [J] Chinese fire protections, 2011 (11): 38-42.).Cigarette processing manufactures Enterprise increasingly pays close attention to the generation of the phenomenon, how to improve with evaluating cigarette aspirate in cigarette fall a performance, be cigarette enterprise urgently Hot issue to be solved(Haibin Wang, Liu Dehu, Wu Zhao just wait cigarette burnings to make a clean sweep of the analysis of phenomenon and research [A] Chinese tobacco association conference Papers collection in 2010,2010,285-287.)
In cigarette smoking to fall a reason for phenomenon occurs very much, said from Cigarette design and machining angle, the possible reason is cigarette Occupied state of the silk in cigarette paper, the mismatch of burn rate and form the encapsulation after cigarette ash not enough etc. in combustion process Caused by reason, and to a kind of cigarette product aspiration procedure decline head tendentiousness power be improve the performance basis, In most cases, the evaluation of this performance is to rely on the personnel that smoke panel test to carry out the evaluation sensuously or under conscious state, people to it For influence is big, the efficiency of acquisition data are low, poor repeatability.The exploitation for falling head tendency detection device simultaneously for cigarette is also the skill The hot issue in art field.
Chinese invention patent(CN 102937639 A)By devising force application apparatus, by implementing to the cigarette in suction Tap, cigarette is observed in whole suction and during tapping and falls and does not fall.In the apparatus, once only can be to a cigarette sample Carry out falling head test, and be that testing efficiency is low by the way that manually cigarette is inserted on clamper, human factor is big.
Chinese invention patent(201310227468.X)It is a kind of device for falling head tendency using rotation mode detection cigarette, It is characterized in that:The device includes base, motor, drives rotating cigarette clamping device and safety guard by motor.The hair It is bright cigarette combustion cone is tested by rotation mode to fall a phenomenon, a kind of new method of combustion cone detection is started, using multiple Detection obtains the statistics of head, and then falls the performance indicator of head tendency during acquisition cigarette burning.The advantages of invention, is: Rotational time, revolution are controllable, and corresponding different samples can use different detection intensities, have wide range of applications;Detection method is simply square Just, the time is short.But the patent focus on using rotation mode detection fall head tendency, do not have to the device for inserting and placing or mode of cigarette Have and go into seriously.
The realization that above patent falls head tendency device for detecting performance and method in cigarette well achieves progress so that The detection that cigarette falls head tendency performance is possibly realized, but current the invention not placement to cigarette in test process and controlling party Formula carries out detailed statement and is controlled accordingly, so as to inevitably introduce human error, influences the repetition of detection Property.
