Cigarette free combustion speed testing device

Abstract

The invention discloses a cigarette free combustion speed testing device which comprises a box body, a cigarette feeding unit, a rotating unit, a cigarette lighting unit, a cigarette pulling and collecting unit, a smoke discharging unit, an image processing unit, a suction unit and a control unit; the box body is of an internal hollow structure, and a fixing plate is arranged in the box body; theinterior of the box body is divided into two parts by the fixing plate, the cigarette feeding unit, the rotating unit, the cigarette lighting unit and the cigarette pulling and collecting unit are fixed to the fixing plate, the smoke discharging unit is fixed to the top of the box body, the image processing unit is further fixed to the smoke discharging unit, and the suction unit and the control unit are fixed to the bottom of the box body. The testing device has the advantages that the testing device replaces manual operation, the efficiency is greatly improved, the influence of the experimental environment on the testing result is small, and the consistency of the testing result is improved; meanwhile, the laboratory environment cannot be polluted, and the harm to the body of a tester isreduced.

Description

technical field [0001] The invention relates to the technical field of quality detection of tobacco products, in particular to a device for testing the free burning speed of cigarettes. Background technique [0002] The free burning speed refers to the average speed at which a non-smoking cigarette moves forward along the front end of the burning zone of the cigarette when it is burning. Cigarette free burning speed is a commonly used auxiliary technical index in designing cigarette products and improving products. This index is a comprehensive reflection of the combustion performance of cigarette paper and shredded tobacco. This index is significantly related to the number of cigarette puffs, smoke tar and CO, and Directly affect the intuitive feeling of consumers in the process of burning and smoking. [0003] In the international standard ISO3612 (tobacco and tobacco products-cigarettes-test of free burning speed), two methods of testing free burning are proposed: direct...

Problems solved by technology

Due to the complexity of the indirect method test, most of the test instruments in the industry currently use the direct method to measure the free burning speed

Among them, the cigarette burning speed tester in the UK uses a counter for calculation and measurement, which is basically the same as manual scribing timing measurement, and the whole process requires manual operation.

The cigarette free-burning tester mainly used in China at present discloses a kind of cigarette free-burning speed tester as the Chinese Utility Model Patent Publication No. CN201188099, and the tester comprises a base, a light source, a visual sensor, a cigarette inserting plate and an igniter. The tester uses an image algorithm to judge free combustion, and can test multiple cigarettes at the same time, but this method still requires manual loading, lighting, and pulling of cigarettes, resulting in low test efficiency

At the same time, the measuring instrument is not designed with a ventilation mechanism. The experimental environment has a great influence on the test results, and the consistency of the test results is poor. At the same time, the smoke generated during the test is exposed to the laboratory environment, which pollutes the laboratory environment and harms the test personnel. harm to the health of
