[0002] In order to verify whether the quality of cigarette tipping paper meets the standards, cigarette factories need to conduct a discoloration test on the cigarette tipping paper. The process of the discoloration test is as follows: cut a small piece of tipping paper sample, and then place the sample in a specified reagent solution. The sample will discolor when immersed in the reagent solution. After the sample is immersed in the reagent solution for a specified time, the discolored sample is taken out, and then a color difference comparison measurement is performed to obtain the corresponding data results. However, there are certain inconveniences in actual operation. After the cigarette tipping paper sample is immersed in the reagent solution, it will curl due to the wetting effect. On the one hand, it will affect the full reaction and contact between the sample and the reagent solution. On the other hand, when taking out the sample for colorimetric operation, the sample needs to be unfolded, and the unfolding process is likely to cause damage to the sample or the shedding of the ink layer on the sample, which can easily have an adverse effect on the test results.

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0027] like Figure 1-Figure 8 As shown, the embodiment of the present application provides a device for preventing sample curling in a decolorization test of cigarette tipping paper, which is used in the process of decolorization test of cigarette tipping paper. Cigarette factories need to perform decolorization test on cigarette tipping paper to check paper quality. The process of decolorization test is roughly as follows: first, place the tipping paper sample paper sheet in a reagent solution for soaking. After soaking, the sample will fade. After soaking for a specified time, take out the sample, and then perform colorimetry on the sample and record the data. There are certain disadvantages in the above test process. After the tipping paper sample is soaked in the reagent solution, the paper will curl when it is wet. The sample curls together. On the one hand, the reagent solution cannot fully contact and react with the sample, affecting the test effect. On the other hand, when the soaked sample is taken out for colorimetry, the curled sample needs to be unfolded. During the unfolding operation, it is easy to damage the paper sample or cause the ink layer on the paper sample to fall off, which will also affect the accuracy of the test. The present application aims to prevent the tipping paper sample from curling during the decolorization test of the tipping paper to avoid the above problems.

[0028] The device includes a first container 100 and a second container 200. The first container 100 has a containing cavity for containing a reagent solution. The second container 200 can be placed in the containing cavity of the first container 100 and taken out from the containing cavity of the first container 100. When in use, the paper sample can be maintained on the second container 200, and then the second container 200 is placed in the first container 100 containing the reagent solution, so that the paper sample is immersed in the reagent solution. After soaking for a specified time, the second container 200 is taken out and the paper sample is taken out for colorimetry.

[0029] In this embodiment, a window 201 is provided on the second container 200, and a connecting component is provided on the second container 200 along the edge of the window 201. The paper sample can be unfolded and maintained on the second container 200 through the connecting component, and the middle part of the paper sample can be exposed at the window 201. After the paper sample is soaked and wetted, under the action of the connecting component on the second container 200, the paper sample can maintain the unfolded state without curling, so that the paper sample is exposed to the outside through the window and can fully contact and react with the reagent solution, thereby effectively improving the test effect.

[0030] Under the maintenance of the second container 200, during the paper decolorization test, when the paper sample is immersed, the sample will not curl, the contact between the sample and the reagent solution is more complete, and it is more convenient to take out the second container 200 for color comparison later. It can be directly compared without causing sample damage or ink layer shedding, thereby improving the accuracy of the decolorization test.

[0031] In some examples, the second container 200 can be a thin flat plate, the window 201 is formed in the middle of the thin flat plate, the connecting component is in the shape of an enclosed frame and is adapted to the shape of the window 201, and the periphery of the window 201 is provided with a groove adapted to the connecting component, and the connecting component can be snapped into the groove to clamp the outer peripheral edge of the paper sample placed at the window 201.

[0032] Preferably, a flat gap cavity 202 is provided on the second container 200, and the window 201 penetrates the second container 200 in the area of ​​the gap cavity 202. The part of the gap cavity 202 along the edge of the window 201 forms a connecting component, and the outer peripheral edge of the paper sample enters the gap cavity 202 at the edge of the window 201 to maintain the paper on the second container 200. It should be noted that the different positions of the window 201 relative to the gap cavity 202 will make the window 201 form a closed enclosure type or an open type, which will cause the maintenance of different angle ranges of the periphery of the paper. For the setting position of the window 201, the maintenance range of the periphery of the paper should account for at least half of the total periphery of the paper, so as to ensure that the paper sample is kept on the second container 200. To ensure effective maintenance of the unfolded state of the paper, preferably, the window 201 penetrates the second container 200 at the middle position of the gap cavity 202. At this time, the window 201 is a closed enclosure type, which can maintain the entire periphery of the paper and improve the stability of maintaining the unfolded state of the paper. In this embodiment, the window 201 penetrates the second container 200 in a direction perpendicular to the plane where the gap cavity 202 is located, and there is a corresponding part of the gap cavity 202 along the entire edge of the window 201. The periphery of the paper sample can enter the part of the gap cavity 202 at the edge of the window 201 and be maintained. At the same time, both sides of the middle of the paper sample are exposed to the outside through the window 201 space so as to fully contact with the reagent solution.

[0033] More preferably, the gap cavity 202 is opened at one side edge of the second container 200 , and the paper sample can be put into the gap cavity 202 at the opening, thereby improving the convenience of putting in the paper sample.

[0034] In this embodiment, the second container 200 is flat as a whole, and the gap cavity 202 is formed inside the second container 200 according to the shape of the second container 200. The components are smaller and the operation is more convenient. Preferably, the outer periphery of the second container 200 is rectangular, and the opening of the gap cavity 202 is located on one side of the outer periphery of the second container 200.

[0035] In one example, the second container 200 is a rectangular flat body. When the second container 200 is placed vertically, the plane where the second container 200 is located is a vertical plane. The gap cavity 202 starts to extend downward from the top of the second container 200, so that the second container 200 forms a flat, thin-walled container with an open top. The window 201 penetrates the second container 200 in a direction perpendicular to the plane where the second container 200 is located, and the window 201 penetrates the middle of the gap cavity 202, so that the entire peripheral edge of the window 201 has an exposed gap cavity 202. By placing the paper sample into the gap cavity 202 at the top of the second container 200, the periphery of the paper sample is maintained by the gap cavity 202, and the paper sample is placed in the gap cavity 202. The middle two sides of the sample are exposed through the window 201. The thickness of the gap cavity 202 should be slightly greater than the thickness of the tipping paper sample. The difference in thickness between the two can be 1-2 mm, which is convenient for the smooth insertion of the paper and can make the paper sample have a certain firmness in the gap cavity 202. After the paper sample is inserted, since the paper itself is not completely flat, the paper has a certain stress deformation and local warping, so that a certain contact can be formed between the periphery of the paper sample and the gap cavity 202, forming a friction limit, and the paper can be completely inserted into the gap cavity 202 downward, so that the bottom of the paper sample is located at the bottom of the gap space of the second container 200, and the maintenance of the paper is more stable.

[0036] In this embodiment, a handle 203 can also be provided on the second container 200. The handle 203 can be used to facilitate holding the second container 200, so that the second container 200 can be easily placed in the reagent solution of the first container 100 and the second container 200 can be taken out of the first container 100. The handle 203 is provided on the edge of the top opening of the second container 200. A handle 203 is provided on each side of the edge of the opening on the second container 200 to improve the overall holding stability. The handle 203 and the second container 200 can be an integrally formed structure with a stronger structural integrity. Preferably, the second container 200 is made of resin, which can maintain a certain shape and is not easily deformed, maintain the paper sample from deformation, and has high chemical stability to prevent corrosion when in contact with the reagent solution.

[0037] More preferably, the first container 100 is a tube with an open top, such as a test tube. A fixing assembly is provided inside the first container 100, and the second container 200 is detachably arranged inside the first container 100 through the fixing assembly. In some embodiments, the fixing assembly includes a card slot 3, and the two side edges of the first container 100 can be clamped in the card slot 3. The card slots 3 are arranged in pairs, and a pair of card slots 3 can be provided, or more than two pairs of card slots 3 can be provided. The height position of each pair of card slots 3 is the same. When there are multiple pairs of card slots 3, the positions in the vertical direction should correspond to a vertical line, so that the second container 200 is arranged in a vertical direction. The device 200 can maintain a vertical state in the first container 100, improve the stability of the paper in the second container 200, and prevent the paper sample from accidentally falling out. Taking a pair of card slots 3 as an example, the card slots 3 are arranged on two opposite sides of the inner wall of the card slot 3 in the first container 100. When the second container 200 moves vertically downward, the edges on the left and right sides of the second container 200 can enter the corresponding card slots 3 until the second container 200 sits down at the bottom of the first container 100. At this time, the edges of the second container 200 are still fixed by the card slots 3 to fix the second container 200.

[0038] In this embodiment, an inner snap ring 4 is provided on the inner wall of the first container 100. The inner snap ring 4 is arranged circumferentially along the inner wall of the first container 100, and the inner snap ring 4 protrudes from the inner wall of the first container 100. The snap groove 3 is formed on the inner snap ring 4, and the opening of the snap groove 3 faces the center of the first container 100. The depth of the snap groove 3 can be to penetrate the entire inner snap ring 4 in the vertical direction, or to penetrate a part of the inner snap ring 4 in the vertical direction near the inner side. The inner snap ring 4 can be integrally formed with the first container 100, or can be provided on the inner wall of the first container 100 by an adhesive.

[0039] A cover 500 may also be provided on the top of the first container 100. When the paper sample is immersed, the cover 500 is used to seal the top of the first container 100 to prevent impurities from entering the first container 100 and affecting the test results. Graduation lines may also be provided on the first container 100 to facilitate the control of the amount of reagent solution used.
