Water-bath temperature control based device for detecting color fastness of filter tip of cigarette

Abstract

The invention discloses a water-bath temperature control based device for detecting the color fastness of a filter tip of a cigarette. The device comprises a heating mantle, a test bench and a cigarette clamping device, and the like, wherein the heating mantle is formed by a water-bath cyclic heating system; the test bench is arranged in the mantle; the cigarette clamping device is mounted and placed on the test bench; the cigarette clamping device comprises an inner barrel and an outer shell; a hermetic air cabin is formed between the inner barrel and the outer shell; a barrel cavity of the inner barrel is a clamping cavity used for clamping the cigarette; the barrel wall of the inner barrel is provided with air vent holes in a uniform distribution manner; a flexible air bag type cylinder-packing layer which is capable of uniformly expanding and contracting along with the intensity of air pressure, is arrayed, along the barrel wall of the inner barrel, in the clamping cavity; the hermetic air cabin is provided with air inlet and outlet hole; the air inlet and outlet hole is provided with an air pipe connected with an external air pump; the hermetic air cabin is also provided witha pressure relief opening. The device has the outstanding characteristics that the device for detecting the color fastness of the filter tip of the cigarette is provided; the device is used for quitewell realizing, in the process of detecting the color fastness of the filter tip of the cigarette, applying uniform and further constant pressure to the surface of the whole filter tip, and the constant-temperature heating is carried out through the water-bath cyclic heating system.

Description

technical field [0001] The invention relates to a device for detecting the color fastness of cigarette filters based on temperature control in a water bath, which uses a water bath circulation system to control the temperature and uniformly applies a certain pressure to the entire cylindrical surface of the cigarette filter to detect the color fastness of the cigarettes. device. Background technique [0002] Cigarette and e-cigarette filters are mouth-contact materials, and the printed layer on the surface of the filter is in direct contact with the consumer's mouth. , prone to fading or fading, the color will be stained on the lips and teeth of consumers, which will affect the health of consumers and the appearance of cigarette products. [0003] In the process of testing the staining fastness of cigarettes and electronic cigarette filters, it is necessary to apply a specific pressure to the test sample in a constant temperature environment and keep it for a certain period...

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
