Cigarette filter color fastness detecting device based on hot air temperature control

Abstract

The invention relates to a cigarette filter color fastness detecting device based on hot air temperature control. The device comprises a test box heated by hot air, as well as a test bench, a cigarette holder and a temperature sensor which are arranged in the box, wherein the cigarette holder comprises an outer sleeve and an inner cylinder arranged in the outer sleeve, and a closed air chamber isformed between the inner cylinder and the outer sleeve; the cavity of the inner cylinder is a cigarette holding cavity, the lower end of the inner cylinder is closed, ventilation holes are uniformly distributed in the inner cylinder wall, and a flexible air bag-type lining layer capable of uniformly stretching and retracting with air pressure is arranged along the inner cylinder wall in the holding cavity; an air inlet and outlet hole is formed in the closed air chamber, and an air tube connected with an external gas pump is arranged on/at the air inlet and outlet hole; the temperature sensoris arranged in the holding cavity and close to the cigarette holding position. The cigarette filter color fastness detecting device has the prominent characteristics that uniform and constant pressureis applied to the entire filter surface during detection of cigarette filter color fastness, and hot air is adopted for constant-temperature heating.

Description

technical field [0001] The invention relates to a detection device for color fastness of cigarette filter tips based on hot air temperature control, which can heat the cigarette filter tips with hot air at a constant temperature within a specified time and under constant pressure conditions. Background technique [0002] Cigarette and e-cigarette filters are mouth-contact materials, and their material or surface printing layer is in direct contact with the consumer's mouth. When consumers smoke, under the action of lip pressure and saliva soaking, if the filter surface printing layer fastness If it is not enough, it is prone to color fading or fading, and the color is stained on the lips and teeth of consumers, which may affect the health of consumers and the appearance of cigarette products. [0003] In the process of testing the color fastness of cigarette filters, it is necessary to apply a specific pressure to the test sample in a constant temperature environment and kee...

AI Technical Summary

Problems solved by technology

At present, there is no special device on the market, which can evenly apply a constant pressure on the circumferential surface of the filter during the inspection of the color fastness of the cigarette filter, and at the same time simulate the temperature of the mouth to maintain a certain contact temperature, and can be applied to various diameters Determination of staining properties of cigarette filters
