Description

Technical Field

[0001] The present application relates to a tobacco material detection device, and in particular to a composite filter rod detection device. Background Art

[0002] Ordinary filter rods are filter segments made of one material, while composite filter rods are functional filter rods, which are first made of two or more materials into filter segments, and then spliced ​​and composited in the axial direction. In composite filter rods, since the two or more filter segments wrapped in forming paper are invisible to the naked eye, the length of each segment cannot be directly measured with a ruler like ordinary filter rods, and special instruments are required for measurement.

[0003] Existing manufacturers mainly use microwave measuring instruments to perform phase detection before the composite machine cuts, and this device has the following disadvantages: (1) The measurement origin of phase detection depends on the cutter setting signal. When the rod speed of the forming machine or the cutter motor speed has an instantaneous drift, the physical rod length between the two setting signals will no longer be consistent, and the phase measurement result will no longer be accurate; (2) The microwave measurement accuracy is about 1mm, and there is a problem of large theoretical error; (3) When the device is accelerated or decelerated, due to the large speed difference, the microwave measurement results in the change process will have greater differences. Among the existing patents, the patent application number is 201310123758X, and the patent name is an offline cigarette or filter rod detection device based on three-dimensional vision technology, which discloses that the control unit transmits the position image of the two ends of the cigarette or filter rod to the data processing computer for analysis and processing to obtain the length of the cigarette or filter rod.

In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0042] A composite filter rod detection device, such as Figures 1 to 4 As shown, it includes a shell 1, and a mold assembly 2, a light source assembly 5 and a measuring assembly 14 are arranged inside the shell 1; the mold assembly 2 includes a filter rod mold box 3 for installing a composite filter rod 13; the light source assembly 5 is arranged below the mold assembly 2, and is configured to provide light that can pass through the composite filter rod 13; the measuring assembly 14 is arranged above the mold assembly 2, and is configured to be able to shoot the pattern formed after the light irradiates the composite filter rod 13, so as to obtain the length of the fiber inside the composite filter rod 13.

[0043] It should be noted that the composite filter rod 13 is formed by axially splicing filter segments of different materials, so there are multiple filter segments in the composite filter rod 13, and each filter segment is composed of fibers of the same material.

[0044] In addition, the light and dark blocks refer to the blocks with different degrees of light and dark formed on the image after the light passes through the composite filter rod 13 due to the different transmittances of filter segments made of different materials. The blocks are marked as light and dark blocks. The light and dark blocks include light blocks 21 and dark blocks 20. The color of the light block 21 is brighter than that of the dark block 20. Since the part carrying the filter segment will block part of the light source 7, the dark block 20 is the location of the filter segment, and the light block 21 is the location of the blank segment. By comparing the dark block 20 displayed on the image with the filter segment at the corresponding position in the original composite filter rod 13, it is calculated that the length value of the dark block 20 corresponds to the length value of the corresponding filter segment, that is, the length value of the fiber of the filter segment is obtained accordingly.

[0045] In order to detect the length of the fibers inside the composite filter rod 13, the present application provides a light source component 5 and a measuring component 14, wherein the light source component 5 is located below the mold component 2. During use, the light source component 5 emits a light source 7 toward the upper mold component 2, and the light can be irradiated into the filter rod mold box 3 of the mold assembly 2. Since the composite filter rod 13 placed in the filter rod mold box 3 contains filter segments made of different materials, and the filter segments formed by fibers of different materials have not only different lengths but also different light transmittances, the lengths of the light and dark blocks presented after irradiation with light are different. The measuring component 14 located above the filter rod mold box 3 takes a picture of the composite filter rod 13 under light irradiation, and the difference between the light and dark blocks in the picture is used to judge the length of each filter segment. First, the corresponding filter segment is obtained based on the obtained dark blocks, and the length value of the dark block is calculated to be the length value of the filter segment, which can also be said to be the length of each fiber inside the composite filter rod 13. Through the cooperation of the measuring component 14 and the light source component 5, the length value of the fiber inside the composite filter rod 13 can be accurately measured, avoiding the traditional method of only being able to measure the overall length of the external filter rod but not being able to obtain the length of the internal filter segment. A variety of different types of filter rods can be stored in the filter rod mold box 3 at the same time, and the length of the filter segments in multiple filter rods can be detected at one time, achieving efficient and accurate detection, and further improving the detection efficiency.
