Technical Field

The invention relates to the field of novel tobacco cigarette quality detection, in particular to heating non-combustible cigarette online quality detection equipment, a method and production equipment.

Background

In recent years, smokers want to reduce the harm of smoking to health, and tobacco enterprises in various countries accelerate the research and development of new types of tobacco which is not burned by heating. Although the tobacco product which is not burnt is heated by a battery, the main object of heating is traditional tobacco, so the taste reduction degree is good, and different from the traditional cigarette, "low-temperature cigarette" designed by taking the concept of "not burning when heating" can ensure that the tobacco leaves are just heated to the degree of giving off the taste, and the tobacco leaves can not be ignited. In general, when ordinary cigarettes are smoked, a large number of harmful substances are generated at high temperature, and most of low-temperature cigarettes are below 300 ℃, so that the harmful substances are reduced. Heating non-combustible tobacco products has a large market space foreseen in China.

The novel tobacco which is not combusted by heating is just started in China, and along with the continuous research and development of cigarette companies for heating non-combusted cigarettes, the brands of the cigarette which is not combusted by heating in China are more and more, and the novel tobacco also represents the direction of market consumption. Because the rolling process is complex due to the characteristic of the cigarette which is not burnt by heating, the finished product cigarette manufactured by adopting different rolling processes has more or less appearance defects, and the defect ratio is far higher than that of the traditional cigarette. Domestic heating non-combustible cigarette rolls up system equipment and all reforms transform out with the equipment of the former traditional cigarette of production, wherein quality testing still continues to use original quality testing system including the dead head, gas leakage, lack the mouth, OTIS four detection items, the cigarette is not burnt in the heating because manufacturing process is different, traditional dead head detects and basically can not use, if be hollow filter rod, lack the mouth and detect sensor also can the problem, see from the in-service use effect, original dead head has not been adapted to the detection that the cigarette was not burnt in the heating, detection effect is relatively poor. OTIS also can not satisfy actual requirement because detection range and sensitivity are limited, and the detection equipment that uses traditional tobacco has the rejection volume in the in-service use big, and detection sensitivity is low, causes the scheduling problem of shutting down easily. According to production practice, the quantity of cigarettes with defects on end faces, raw cigarette material units and cigarettes with defects on cigarette rods is not few, and currently used cigarette production equipment without heating combustion has no visual detection system outside cigarette end faces, so that defective cigarettes flow into the market, and the enterprise image of cigarette production enterprises is adversely affected.
