Embodiment Construction

[0031] 1. Filter Rod Measuring Platform

[0032] Such as image 3 As shown, the filter rod measuring platform includes a carrying device and a light-sealed housing 45 thereof. The carrying device includes a carrying groove 41 for laying the filter rod flat. The carrying groove is a V-shaped groove with a notch width of 10mm and an opening angle of 45°. A light guide groove 42 with a depth of 5mm is provided below the bearing groove 41, and a strong linear light source 43 is arranged at the bottom of the light guide groove 42 along the length direction of the light guide groove, and the strong linear light source 43 is welded on the PCB circuit plate 44. The strong linear light source is composed of densely arranged SMD LEDs. The SMD LEDs are bright, Lambertian, and white SMD LEDs. The interval between SMD LEDs is 3mm. The V-shaped groove design can fix the filter rod to be tested, and the use of 45° bevel increases the contact area between the slope of the groove and the fil...

Abstract

The invention relates to a filter stick measuring table, a nondestructive measurement device and a method for the length of segmented rods of a filter stick. The nondestructive measurement device comprises the filter stick measuring table, an imaging device and a controller. The filter stick measuring table comprises a bearing device and a light sealing outer shell. The bearing device comprises a bearing groove for enabling filter stick to be placed horizontally. A light guide groove is arranged below the bearing groove. A strong-light linear light source is arranged at the bottom of the light guide groove along the length direction of the light guide groove. The strong-light linear light source is welded on a printed circuit board (PCB). According to the nondestructive measurement device, a light transmission method is mainly adopted, a highlight light source is utilized to irradiate the filter stick. Due to the fact that the absorption strength of different filter stick segments to light rays, an imaging method is used for catching the light intensity weakened through transmission. The image gray values corresponding to the different filter stick segments are different. The length of the gray segments can be measured though an image, and then the length of each filter stick segment of the filter stick can be obtained. Consequently, the nondestructive measurement of the length of each filter stick segment of the filter stick is achieved.

Description

technical field [0001] The invention relates to a measuring table for a composite filter rod for cigarettes, non-destructive measuring equipment and a method for the length of each segmented material rod in the filter rod. Background technique [0002] The composite filter rod for cigarettes is composed of two or more material rods of different materials, such as figure 1 As shown, it is mainly composed of cellulose acetate filter rod 6 and material rod 7 with selective adsorption performance, and the position shown in 8 is the cutting position. With the deepening of harm and coke reduction work in the tobacco industry, binary and ternary composite filter rods have been increasingly used in cigarettes. Activated carbon materials are usually added to the rods with adsorption properties, which can effectively Reduce the amount of tar in cigarettes and harmful components in smoke. [0003] Composite structure is one of the technical index requirements in the quality inspectio...
