Embodiment

[0032] A method for measuring characteristic parameters of a grooved filter rod, using a workbench, a ring light source, a digital camera with 8 million pixels, a sampling tool, a sample plate, and a computer with a built-in measurement program for the characteristic parameters of a grooved filter rod. In addition to the detection function of the original standard, it also has the following functions: calculate the groove area, calculate the average value of the groove area, and calculate the ratio of the groove area.

[0033] as attached figure 1 As shown, the assay method includes the following steps:

[0034] 1) Use a cutting tool to cut the filter rod into several thin slices with a thickness of 5 mm as samples, and place them in the sample holes of the sample plate;

[0035] 2) The sample plate is placed in the ring light source, the sample image is taken by a digital camera, and input into the computer with the built-in measurement program of the characteristic paramete...

Abstract

The invention provides a determining method for grooved filter stick feature parameters. A determining device used by the method comprises a workbench, an annular light source, a digital camera, a sample plate, and a computer with a built-in grooved filter stick feature parameter determining program. The determining program has the following functions: scaling sample images, recording groove number, displaying concentric circles, identifying groove depth data, calculating average groove depth, displaying normal, identifying groove width, calculating average groove width, calculating groove area and groove area ratio, and calculating standard deviation and variable coefficient of part of parameters. The determining method includes: computer calculating, computer synthesis, and displaying and outputting data through the computer. By increasing resolution of the digital camera and upgrading the computer program, automation level and determining precision are increased, groove width determining and groove area determining are added, comprehensive determining data is achieved, and convincing determining of grooved filter stick features is achieved.

Description

[0001] technical field [0002] The invention relates to the characteristic parameter of a grooved filter rod and a measuring method thereof. Background technique [0003] In the industry standard of "YCT223.1-2007 Fiber Acetate Grooved Filter Rod" and the "Measurement Method for Characteristic Parameters of Fiber Acetate Grooved Filter Rod" published in the 4th issue of "Tobacco Science and Technology" in 2010, it is proposed that microscopic imaging technology can be used to detect The cross-section of the grooved filter rod is collected graphically, and the characteristic parameters of the grooved filter rod are measured by the graphical analysis software to obtain the number of grooves and the groove depth of the sample. Measuring instruments include: stereo microscope (magnification 8 times to 50 times); ring light source; digital camera; standard micrometer; sample plate; cutting tools. The number of groove characteristic parameters measured by the instrument used in ...
