Description

Technical Field

[0001] This utility model relates to the technical field of measuring the smoldering rate of cigarette paper, and specifically to a measuring device for the smoldering rate of cigarette paper. Background Technology

[0002] Currently, the mainstream equipment for detecting the smoldering rate of cigarette paper is the horizontal smoldering type, which mostly uses temperature sensors or digital cameras to detect the smoldering rate. Regardless of which method is used, there are certain drawbacks. For example, using infrared methods alone results in slow rate update speeds, inability to measure serration depth, inability to determine the number of fallen sheets, and delayed detection of abnormalities such as flameout. Using digital cameras alone is susceptible to data loss and misjudgments due to the smoldering line being obscured by cigarette ash or smoldering dust.

[0003] The prior art patent with announcement number CN102590547B, entitled "A Method and Device for Measuring the Smoldering Rate of Cigarette Paper," specifically discloses a method and device for measuring the smoldering rate of cigarette paper. This method includes a base, a combustion chamber cover, a baffle plate installed at the rear end of the base, the combustion chamber cover hinged to the upper edge of the baffle plate, a smoke exhaust device above the baffle plate, and an infrared detection device below the smoke exhaust device. The infrared detection device includes several infrared probes, a support rod on the base corresponding to the infrared probes of the infrared detection device, a support shaft perpendicular to each support rod, the center of each support rod hinged to the support shaft, a bar electromagnet at each end of the support shaft, and a heating resistance wire between the support shaft and the electromagnet on the right. This prior art uses an infrared detector to detect the smoldering rate. However, using infrared alone has drawbacks: slow rate update speed, inability to measure serration depth, inability to determine the number of fallen pieces, and difficulty in timely detection of abnormal situations such as flameout.

[0004] The technical problem to be solved by this utility model is: how to provide a device for measuring the smoldering rate of cigarette paper that integrates image recognition and infrared detection technology.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

The infrared detection mechanisms and the camera are both connected to the computer controller.

[0007] This application adopts a symmetrical infrared detector setup and integrates the infrared detector setup with camera vision. Compared with the existing horizontal smoldering rate measuring instrument, it can accurately detect the smoldering line position and avoid misjudgment and loss of experimental data caused by sample ash rolling.

[0008] As a further embodiment of this utility model: the infrared detection mechanism includes an upper infrared detector and a lower infrared detector symmetrically arranged on the upper and lower sides of the cigarette paper clamping mechanism, wherein the upper infrared detector is located diagonally above the cigarette paper clamping mechanism and fixed on one side of the box, and the lower infrared detector is located diagonally below the cigarette paper clamping mechanism and installed inside the box.

[0009] As a further embodiment of this utility model: the upper infrared detector and the lower infrared detector are each provided with several probes at equal intervals on the side facing the cigarette paper clamping mechanism.

[0011] As a further embodiment of this utility model: an exhaust vent is provided on one side of the housing and above the upper infrared detector, and an exhaust filter is installed at the exhaust vent, wherein the exhaust vent is connected to a fan installed inside the housing.

[0012] As a further embodiment of this utility model: the cigarette paper clamping mechanism includes several support rods installed on the workbench, and clamping devices are provided on both sides of the several support rods.

[0015] As a further embodiment of this utility model: an ash collection chamber is provided on the box body and directly below the workbench.

[0016] As a further embodiment of this utility model, a sealing door is slidably connected to one side of the box body and directly above the workbench.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] First, this application adopts a symmetrical infrared detector setup and integrates the infrared detector setup with camera vision. Compared with the existing horizontal smoldering rate measuring instrument, it can accurately detect the smoldering line position, avoid misjudgment caused by sample ash and loss of experimental data. In addition, this application can also measure experimental parameters such as the depth of cigarette paper serrations and the number of pieces falling off during the smoldering process by combining an industrial camera with an infrared detector.

[0019] Secondly, this application features a novel sealing door designed on the enclosure. The sealing door is designed to slide up and down, which increases the sealing performance during the smoldering process, prevents interference from the external environment during the smoldering process, and is more convenient and labor-saving to operate.

[0020] Finally, this application only requires changing the sample in each set of experiments, without changing the detection equipment. The sample is clamped and supported by the clamping device and support rod, which has high applicability and simplifies the operation process of the unified experiment. Attached Figure Description

[0030] Reference Figure 1 One side of the housing 1 is provided with a cigarette paper smoldering rate worktable. Several support rods 6 are provided on the worktable to support the cigarette paper. The support rods 6 can be raised and lowered. When they rise, they support the cigarette paper, and when the smoldering ends, they fall down. Ignition devices 5 are provided on both sides of the support rods 6. Clamping devices 4 are provided on the outside of the two ignition devices 5. It should be noted that the clamping devices 4, the ignition devices 5 and the support rods 6 are located on the same horizontal plane.

[0031] Reference Figure 1 and Figure 2 On the same side of the housing 1 and the workbench, and directly above the workbench, a sealing door 2 is installed. The sealing door 2 can slide up and down on the housing 1. When the sealing door 2 slides down, it can completely seal and cover the workbench.

[0032] Reference Figure 3 An upper infrared detector 9 is installed diagonally above the support rod 6, and a lower infrared detector 11 is installed diagonally below it. Both the upper infrared detector 9 and the lower infrared detector 11 include several detection probes. The number of probes is the same as the number of support rods 6, and their positions correspond to each other. The upper infrared detector 9 and the lower infrared detector 11 can detect the smoldering of cigarette paper. The upper infrared detector 9 and the lower infrared detector 11 are also equipped with a paper detection lamp 13 and a paper detector 14 for detecting the position of the paper.

[0033] Furthermore, an industrial camera 12 is installed directly above the cigarette paper smoldering rate worktable for image recognition of the cigarette paper smoldering state, and image analysis records data such as the maximum serration depth and the number of pieces falling off the sample from the beginning to the end of smoldering.

[0034] Reference Figure 2 An exhaust filter 7 is installed on one side of the housing 1 and above the upper infrared detector 9. The exhaust filter 7 is connected to the fan 10 inside the housing 1. The power of the exhaust fan 10 is controllable and is used to remove smoke and other fumes generated by the smoldering of cigarette paper.

[0035] Reference Figure 1 A computer controller 3 is installed on one side of the housing 1. The computer controller 3 has a computer control system. The fan 10, industrial camera 12, upper infrared detector 9 and lower infrared detector 11 are all connected to the computer controller 3 and can upload the data they detect to the computer control system. The computer control system includes control acquisition devices that can be used to record data generated during the smoldering process, such as smoldering rate, cigarette paper serration depth, number of pieces falling off and other data.

[0036] Furthermore, an ash collection chamber 8 is provided on one side of the box 1 and directly below several support rods 6. The ash produced after the cigarette paper smolders can fall into the ash collection chamber 8 for collection. After collection, it is poured out in a unified manner to avoid affecting the surrounding environment.

[0037] The specific operating principle of this application is as follows:

[0038] (1) First, open the sealing door 2 and place the two ends of the cigarette paper between the two clamping devices 4. At this time, the paper detection lamp 13 on the upper infrared detector 9 and the lower infrared detector 11 detects the sample. After the response time is reached, the clamping device 4 sucks and positions the cigarette sample.

[0039] (2) Slide the sealing door 2 downwards, detect the closing electromagnetic signal, and the ignition device 5 automatically ignites the cigarette paper;

[0040] (3) When the first group of infrared detectors detects the smoldering line of the cigarette paper, the timer on it starts to start timing, and at the same time, the camera 12 is controlled to take pictures of the cigarette sample and upload them to the computer controller 3. The background performs image analysis on the sample.

[0041] (4) After each set of infrared probes responds, the corresponding support rod 6 falls down, and the refresh smoldering rate is calculated based on the smoldering distance and smoldering time;

[0042] (5) Image analysis records the maximum serration depth and the number of pieces falling off the cigarette sample from the beginning to the end of smoldering;

[0043] (6) When the last set of infrared probes detects the smoldering wire, stop the timing, output the recorded data results, reset the support rod 6, start the fan 10 to exhaust smoke, and release the clamping device 4.

[0044] (7) Open the sealing door 2, put in the next sample, repeat the test until 10 samples are completed, and the experiment will end automatically.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
