Description

Technical Field

[0001] The utility model relates to the technical field of cigarette paper, in particular to a cigarette paper fluorescence brightness test calibration fixing device. Background Art

[0002] Fluorescent brighteners are toxic and carcinogenic. The tobacco industry has clearly stipulated that fluorescent brighteners shall not be added to cigarette papers such as cigarette paper, filter rod forming paper, cigarette tipping paper, and cigarette liner paper. The fluorescent brightness and whiteness of cigarette paper are usually characterized by D65 fluorescent brightness and fluorescent whiteness, and are measured using a whiteness tester and monitored as quality and safety indicators for tobacco materials to improve the safety of cigarette products.

[0003] At present, when a whiteness tester is used to test the D65 fluorescence brightness of cigarette paper, a standard working plate calibration bracket provided by the instrument manufacturer is used to transfer the standard working plate and calibrate the instrument. Calibration is a key step before testing and is related to the accuracy of the test results. However, the calibration bracket has no fixed fulcrum, and different standard working plates have different weights, resulting in an unstable center of gravity after the working plate is placed on the bracket. It is particularly easy to fall, contaminating and damaging the standard working plate, resulting in inaccurate test results.

[0004] Therefore, a cigarette paper fluorescence brightness test calibration fixture is provided to solve the problem that the support rotates due to imbalance and center of gravity offset, causing the working plate to fall and be damaged, effectively protecting the standard working plate and ensuring accurate test results.
