Description

Technical Field

[0001] The present invention relates to the technical field of cigarette identification, and more specifically to a cigarette shredded tobacco blending ratio inspection device, a use method and an identification method thereof. Background Art

[0003] Cigarette tobacco formula design is the core technology of cigarette products. Authentic cigarette tobacco is generally composed of leaf shreds, expanded leaf shreds, expanded stem shreds and reconstituted tobacco. Therefore, the inspection of different tobacco blending conditions can be used as an important basis for identifying the authenticity of cigarettes. At present, the inspection of tobacco blending conditions mainly relies on the experience of identification personnel, and is carried out in conjunction with the use of a wide variety of identification tools. Therefore, there are often problems such as low accuracy of results, large workload, long time consumption, and low efficiency.

[0004] At the same time, the current inspection of the blending of cigarette tobacco is mainly focused on uniformity inspection. For example, Chinese patent publication number CN110823754A discloses a method for inspecting the uniformity of blending of cigarette formula tobacco. The first step of the method is to obtain the weight percentage content W1 and W2 of the target chemical substances contained in the two admixtures constituting the tobacco part of the cigarette to be inspected, respectively. The second step is to determine the weight percentage content Wc of the target chemical substance contained in the tobacco part of the cigarette. The third step is to obtain the measured blending ratio Q1 of the two admixtures according to Wc, W1, and W2, that is, Qc= / (W1-W2)×100%. The fourth step is to obtain the deviation value Rc according to Qc and the preset blending ratio Qy, that is, Rc= / Qy. If the absolute value of Rc does not exceed the preset value, it is determined that the blending is uniform; otherwise, it is determined that the blending is uneven. The target chemical substance is one or at least two of cellulose, hemicellulose, and lignin.

[0005] The problem with the above technical solution is that it is a method model established based on the content of chemical substances contained in tobacco shreds, and does not directly test the tobacco shreds. Therefore, the uniformity measurement results are prone to large deviations. Secondly, it can only test the blending uniformity of tobacco shreds components, but cannot test the actual blending ratio of each component in the tobacco shreds. Therefore, the test data is difficult to use as a key basis for identifying the authenticity of cigarettes. Summary of the invention

[0006] In view of the above situation, in order to overcome the problems of low accuracy, large workload, long time consumption and low efficiency in the inspection of tobacco blending ratio of cigarettes when identifying the authenticity of cigarettes, in addition, the inspection is focused on the inspection of the uniformity of tobacco blending, and the tobacco is not directly inspected during the inspection, resulting in large deviations in the uniformity inspection results, and the actual blending ratio of each component in the tobacco cannot be determined. The purpose of the present invention is to provide a device for directly inspecting the tobacco blending ratio, thereby significantly improving the accuracy of the inspection result and making the cigarette authenticity identification result more objective, and the inspection can be completed one by one without the aid of other additional tools, thereby having a small workload, short time consumption and high inspection efficiency.

DETAILED DESCRIPTION

[0057] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0058] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the product of the invention is usually placed when in use. They are only for the convenience of simplifying the description, and do not indicate or imply that the directions are specific directions that must be possessed, and specific directions structures and operations, and therefore should not be understood as limitations on the present invention.

[0059] like Figures 1 to 4 As shown, the present invention firstly relates to a cigarette tobacco blending ratio testing device, which comprises a testing box 1, wherein the testing box 1 has an upper filter cavity 101, a middle filter cavity 102 and a lower filter cavity 103 inside. It can be understood that the upper filter cavity 101, the middle filter cavity 102 and the lower filter cavity 103 are arranged in sequence from top to bottom;

[0060] An upper filter screen 2 and an upper collecting hopper 3 are detachably connected in the upper filter chamber 101. The upper filter screen 2 is located above the upper collecting hopper 3, and an upper disassembly port 101a is provided on the side wall of the upper filter chamber 101. The upper disassembly port 101a is opposite to the upper filter screen 2 and the upper collecting hopper 3, so that the upper filter screen 2 and the upper collecting hopper 3 can be disassembled from the upper filter chamber 101 through the upper disassembly port 101a, and can be reassembled into the upper filter chamber 101 accordingly. When whole shredded tobacco is separated from crushed tobacco, all the inspected shredded tobacco is placed on the upper filter screen 2. Under the action of gravity, the crushed tobacco with a smaller diameter will pass through the filter holes of the upper filter screen 2 and fall into the upper collecting hopper 3 below, while the tobacco with a larger diameter will be retained above the upper filter screen 2, thereby completing the separation of whole shredded tobacco from crushed tobacco.

[0061] The middle-layer filter cavity 102 is detachably connected with the middle-layer filter screen 4 and the middle-layer collecting hopper 5. The middle-layer filter screen 4 is located above the middle-layer collecting hopper 5 and can rotate and move up and down relative to the middle-layer collecting hopper 5, which allows the middle-layer filter screen 4 to switch between horizontal and vertical states, and at the same time allows it to move up and down in the middle-layer filter cavity. A middle-layer disassembly and assembly port 102a is provided on the side wall of the middle-layer filter cavity 102 corresponding to the upper-layer filter screen 2 and the upper-layer collecting hopper 3, so that the middle-layer filter screen 4 and the middle-layer collecting hopper 5 can be disassembled from the middle-layer filter cavity 102 through the corresponding middle-layer disassembly and assembly port 102a, and can also be reassembled into the middle-layer filter cavity 102 accordingly, and a middle-layer liquid injection port 102b and a middle-layer liquid discharge port 102c are provided on the side wall of the middle-layer filter cavity 102. The middle-layer liquid injection port 102b is used to inject anhydrous ethanol into the middle-layer filter cavity 102, and can be discharged through the middle-layer liquid discharge port 102c. Discharge to the outside. When the expanded shreds are separated, the middle-layer collecting hopper 5 is removed and the whole shredded tobacco separated by the upper-layer filter chamber 101 is put in, and then put back. Then, anhydrous ethanol is injected into the middle-layer filter chamber 102. If there are expanded shreds in the whole shredded tobacco, then according to the physical properties of the expanded shreds, they will float on the anhydrous ethanol, and the remaining whole shredded tobacco will settle at the bottom of the middle-layer collecting hopper 5. Then, the middle-layer filter screen 4 is rotated and moved toward the top of the middle-layer filter chamber 102, so that the middle-layer filter screen 4 will be able to push the expanded shreds upward and separate them from the anhydrous ethanol. After the middle-layer filter screen 4 is taken out, the content of the expanded shreds can be checked. Finally, the anhydrous ethanol is discharged from the middle-layer drainage port 102c. The remaining whole shredded tobacco can be collected uniformly after the middle-layer collecting hopper 5 is disassembled. Then, the expanded stem shreds that may exist in the remaining whole shredded tobacco will be further separated in the lower-layer filter chamber 103.

[0062] Similar to the middle filter chamber 102, the lower filter chamber 103 is detachably connected with a lower filter screen 6 and a lower collecting hopper 7. The lower filter screen 6 is located above the lower collecting hopper 7 and can rotate and move up and down relative to the lower collecting hopper 7. A lower disassembly opening 103a is provided on the side wall of the lower filter chamber 103 corresponding to the lower filter screen 6 and the lower collecting hopper 7. The lower filter screen 6 and the middle collecting hopper 5 can be disassembled from the lower filter chamber 103 through the corresponding lower disassembly opening 103a, and can also be reassembled into the lower filter chamber 103 accordingly, so that the middle filter chamber 103 can be reassembled. After the expanded stem shreds, reconstituted tobacco leaves and large-volume shredded leaves obtained from the filter chamber 102 are placed in the lower collecting hopper 7, they are moved to the lower filter chamber 103 through the lower collecting hopper 7. A lower liquid injection port 103b and a lower liquid discharge port 103c are also provided on the side wall of the lower filter chamber 103. The lower liquid injection port 103b is used to inject liquid nitrogen into the lower filter chamber 103. If there are expanded stem shreds in the remaining whole shredded tobacco, the expanded stem shreds are separated from the reconstituted tobacco leaves and large-volume shredded leaves by utilizing the property that the expanded stem shreds easily float on liquid nitrogen. The lower filter screen 6 is then rotated and the liquid nitrogen in the lower filter chamber 103 is discharged. The lower filter screen 6 is moved upward, so that the lower filter screen 6 will be able to push the expanded stem shreds upward to separate from the liquid nitrogen. After the lower filter screen 6 is taken out, the content of the expanded stem shreds can be tested. Finally, the liquid nitrogen is discharged from the middle liquid discharge port 102c. The remaining whole shredded tobacco that may contain reconstituted tobacco leaves and large-volume shredded leaves can be collected uniformly after the lower collecting hopper 7 is disassembled. Therefore, the testing device of the present invention can be used alone to simultaneously separate whole shredded tobacco from broken shredded tobacco, as well as expanded shredded leaves and expanded stem shreds. The separation of whole shredded tobacco from broken shredded tobacco is a physical filtration separation using gravity, and the separation of expanded shredded tobacco leaves and expanded stem shreds is a physical filtration separation using gravity. The shredded tobacco and expanded stem shreds are separated by chemical separation. At the same time, if reconstituted tobacco leaves and large-volume shredded leaves are present in the remaining whole shredded tobacco obtained after filtration in the lower filter chamber, they can be directly separated by the color difference method. The separation difficulty is relatively low. Therefore, the blending ratio and uniformity of each type of shredded tobacco can be directly calculated and determined after separation, without the aid of other additional inspection tools. During the inspection process, the reliance on experience can be reduced, the accuracy of the separation results can be improved, and it can be ensured that the inspection data can be used as the key basis for identifying the authenticity of cigarettes, and the workload of inspectors can be reduced, the inspection time can be shortened, and the inspection efficiency can be improved.

[0063] like Figure 3 and Figure 4As shown, a first guide groove 101b is provided on the inner wall of the upper filter chamber 101, and the first guide groove 101b is opposite to the upper disassembly and assembly port 101a, and corresponds to the upper filter screen 2 and the upper collecting hopper 3. The upper filter screen 2 and the upper collecting hopper 3 are slidably fitted in the first guide groove 101b, and the inspector can control the upper filter screen 2 and the upper collecting hopper 3 to slide horizontally along the first guide groove 101b toward the corresponding upper disassembly port for disassembly, or re-embed them into the first guide groove 101b for reassembly, thereby simplifying the disassembly and assembly process of the upper filter screen 2 and the upper collecting hopper 3, facilitating and timely removing the filtered whole shredded tobacco and broken shredded tobacco, reducing the workload of the inspector, shortening the inspection time, and improving the inspection efficiency.

[0064] like Figure 1 , Figure 3 and Figure 4 As shown, the upper filter screen 2 has two layers, and the two layers of filter screens are arranged opposite to each other up and down, and the filter holes of the two upper filter screens 2 have different aperture sizes, and the filter holes of the upper filter screen 2 are larger than the filter holes of the lower upper filter screen 2. In this way, tobacco of different volumes can be more finely subdivided, so that the determined crushing rate and whole shred rate results are more accurate.

[0065] like Figure 3 and Figure 4 As shown, the inner wall of the middle filter cavity 102 is provided with a second guide groove 102d, a first lifting guide groove 102e and a third guide groove 102f, wherein the second guide groove 102d and the third guide groove 102f are both in a transverse direction, and the second guide groove 102d and the third guide groove 102f are both opposite to the middle disassembly opening 102a, and the first lifting guide groove 102e is in a longitudinal direction relative to the middle filter cavity 102 and is connected to the second guide groove 102d, thereby forming an overall L-shaped guide groove structure, and the middle filter screen 4 is movably matched in the second guide groove 102d and the first lifting guide groove 102e, so that lifting and disassembly can be completed. , and can be lifted and flipped by rotating the lifting assembly 8 within a limited time. The middle-layer collecting hopper 5 is slidably matched in the third guide groove 102f. The inspector can control the middle-layer collecting hopper 5 to slide horizontally along the second guide groove 102d in the direction of the corresponding middle-layer disassembly port for disassembly, or re-embed it in the second guide groove 102d for reassembly. The above arrangement simplifies the disassembly and assembly process of the middle-layer filter screen 4 and the middle-layer collecting hopper 5, and facilitates the removal of the expanded leaf shreds received by the middle-layer filter screen 4, as well as the expanded stem shreds, reconstituted tobacco leaves and large-volume leaf shreds deposited in the middle-layer collecting hopper 5, thereby further reducing the workload of inspectors, shortening the inspection time, and improving the inspection efficiency.

[0066] like Figure 3 and Figure 4As shown, a fourth guide groove 103d, a second lifting guide groove 103e and a fifth guide groove 103f are provided on the inner wall of the lower filter chamber 103, the fourth guide groove 103d and the fifth guide groove 103f are both opposite to the middle-layer disassembly and assembly port 102a, and the fourth guide groove 103d is connected to the second lifting guide groove 103e, the lower filter screen 6 is movably fitted in the fourth guide groove 103d and the second lifting guide groove 103e, and the lower collecting hopper 7 is slidably fitted in the fifth guide groove 103f, the fourth guide groove 103d and the second lifting guide groove 103e have the same effect as the second guide groove 102d and the first lifting guide groove 102e, that is, it is convenient for the disassembly and assembly of the lower filter screen 6, and the fifth guide groove 103f has the same effect as the third guide groove 102f, that is, it is convenient for the disassembly and assembly of the lower collecting hopper 7, so it is not described here.

[0067] like Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, both the middle filter chamber 102 and the lower filter chamber 103 are provided with a rotating lifting assembly 8. More specifically, the rotating lifting assembly 8 in the middle filter chamber 102 is slidably matched with the second guide groove 102d and the first lifting guide groove 102e, and is detachably connected to the middle filter screen 4. The rotating lifting assembly 8 in the lower filter chamber 103 is slidably matched with the fourth guide groove 103d and the second lifting guide groove 102e, and is detachably connected to the lower filter screen 6. When the rotating lifting assembly 8 slides along the second guide groove 102d and the first lifting guide groove 102e, and along the fourth guide groove 103d and the second lifting guide groove 102e, the corresponding middle filter screen 4 and the lower filter screen 6 are controlled to flip and lift, and the rotating lifting assembly 8 itself can rotate so that The middle filter screen 4 and the lower filter screen 6 can be disassembled and assembled. In the initial state, the middle filter screen 4 and the lower filter screen 6 remain in a lowered state to avoid blocking the expanded leaf filaments and expanded stem filaments floating upward after the anhydrous ethanol is injected into the middle filter cavity 102. When the expanded leaf filaments float on the anhydrous ethanol, the rotating lifting component 8 controls the middle filter screen 4 and the lower filter screen 6 to turn over. During the rising process, the expanded leaf filaments and expanded stem filaments will be intercepted and kept away from the anhydrous ethanol liquid surface and the liquid nitrogen liquid surface below, respectively. Finally, the rotating lifting component 8 is separated to remove the middle filter screen 4 and the lower filter screen 6 from the middle filter cavity 102 and the lower filter cavity 103, respectively, so that the expanded leaf filaments and expanded stem filaments received can be taken out.

[0068] like Figure 7As shown, the rotary lifting assembly 8 includes a slide 801, a turntable 802 and a top seat 803. The slide 801 is slidably matched with the middle filter chamber 102 and the lower filter chamber 103. Specifically, the rotary lifting assembly 8 in the middle filter chamber 102 is slidably matched with the second guide groove 102d and the first lifting guide groove 102e through the slide 801, and the rotary lifting assembly 8 in the lower filter chamber 103 is slidably matched with the fourth guide groove 103d and the second lifting guide groove 102e through the slide 801. The turntable 802 is hinged on the slide 801, so that it can rotate around the slide 801. The connection position rotates, and the top seat 803 is arranged on the turntable 802, and is detachably connected to the middle filter screen 4 and the lower filter screen 6, so that when the turntable 802 rotates, the top seat 803 can drive the middle filter screen 4 and the lower filter screen 6 to flip synchronously, and the flipping can be achieved by cooperating with the sliding of the slide seat 801. It should be mentioned that there are two groups of rotating lifting components 8 corresponding to the middle filter screen 4 and the lower filter screen 6, and the corresponding two groups of rotating lifting components 8 are opposite to each other on the left and right, so that the middle filter screen 4 and the lower filter screen 6 can be stably supported after being flattened to avoid overturning.

[0069] like Figure 7 As shown, a slot 803a is provided on the top seat 803, and the slot 803a is connected with the front and rear ends of the top seat 803, and the side edges of the middle filter screen 4 and the lower filter screen 6 are inserted into the slot 803a. Based on the above arrangement, the middle filter screen 4 and the lower filter screen 6 are allowed to slide out of the docking with the top seat 803 to achieve autonomous disassembly, and when they need to be reinstalled, they can also be connected to the top seat 803 by embedding the side edges into the slot 803a and moving them.

[0070] Combination Figures 1 to 7 The present invention also relates to a method for using the above-mentioned cigarette tobacco blending ratio inspection device, which comprises the following steps:

[0071] S1: dismantle the cigarette package to obtain cigarette shreds, place the whole shredded tobacco on the upper filter screen 2, filter the shredded tobacco downwards, the shredded tobacco is a small-volume leaf shred, and the upper collecting hopper 3 collects the shredded tobacco, which is generally a small-volume leaf shred.

[0081] Case 1: The sample cigarettes are judged to be fake because the sample cigarettes do not have the corresponding ingredients in the genuine cigarettes.

[0082] Case 2: The components that do not exist in the genuine cigarettes appear in the sample cigarettes, and the sample cigarettes are judged to be fake

[0083] Case 3: The components present in the genuine cigarettes also exist in the sample cigarettes, and need to be calculated and re-determined:

[0084] Case 4: The ingredients that do not exist in the authentic cigarettes also do not appear in the sample cigarettes, so there is no need for calculation and secondary determination;

[0085] S2: weighing the whole shredded tobacco to obtain the weight T of the whole shredded tobacco, weighing the whole shredded tobacco to obtain the weight W of the whole shredded tobacco, weighing the broken shredded tobacco to obtain the weight F of the broken shredded tobacco, weighing the expanded shredded leaves to obtain the weight L of the expanded shredded leaves, weighing the expanded shredded stems to obtain the weight S of the expanded shredded stems, separating the reconstituted tobacco leaves and the large-volume shredded leaves by the color difference method, and weighing the reconstituted tobacco leaves and the large-volume shredded leaves to obtain the weight R of the reconstituted tobacco leaves and the weight C of the large-volume shredded leaves;

[0086] S3: Calculate the deviation rate of each tobacco component:

[0087] Deviation rate L = / ;

[0088] Deviation rate S = / ;

[0089] Deviation rate R = / ;

[0090] Deviation rate W = / ;
