[0035] See Figure 6As shown, the appearance of a cigarette mainly includes cigarette paper a, tipping paper b, cigarette mark c set on the periphery of cigarette paper a, and tobacco inside cigarette paper a. A filter is set inside tipping paper b. In order to verify the overall length and circumferential diameter of the cigarette, whether the position of cigarette mark c reaches the preset length or is within the preset position range, and to verify the appearance defect size on cigarette paper a and tipping paper b, and whether the indentation depth of tobacco in the end face of cigarette paper a exceeds the standard range, it is necessary to use professional tools for inspection. This application uses the proposed cigarette inspection device to inspect the above-mentioned inspection items to facilitate inspectors to conduct cigarette appearance inspection.

[0036] This application provides a cigarette inspection device, which includes a plate 100, a scale 200, and a measuring scale 300. Specifically, the plate 100 has a first side 101 and a second side 102. The first side 101 is provided with a measuring hole 110 and a placement groove 120. The scale 200 is disposed on the first side 101 and is located on one or both sides of the placement groove 120. The measuring scale 300 is rotatably mounted on the second side 102.

[0037] Please see Figure 1 As shown, in some specific embodiments, when it is necessary to detect the circumference of a cigarette, the cigarette can first be passed through the measuring hole 110. The diameter of the cigarette can be determined by whether the cigarette can pass through the measuring hole 110, thereby determining the range of the cigarette's circumference.

[0038] Furthermore, such as Figure 1 As shown, when it is necessary to detect whether the cigarette label is located in the preset position on the cigarette paper, the entire cigarette needs to be placed in the corresponding brand placement groove 120, so that the filter end of the cigarette abuts against the end face of the placement groove 120. Then, the reading of the cigarette label is observed through the gradation line 200 on one side in the radial direction. The position of the cigarette label is observed by the reading to see if it is located in the preset position, thereby determining whether the position of the cigarette label meets the process requirements.

[0039] When testing cigarettes of different brands and models, the tobacco shreds of the cigarette can be placed against the end of the placement groove 120, and the reading of the mark can be observed through the radial engraving line 200 to determine whether the position of the cigarette of that model and specification meets the process requirements.

[0040] It should be noted that the position of the markings on cigarettes varies depending on the specifications and models, and therefore the position of the corresponding 200 markings will also be different. In practice, different markings can be set according to the different specifications and models of cigarettes, but no specific restrictions are made here.

[0041] For further information, please continue reading. Figure 1As shown, the measuring scale 300 can be rotatably mounted on the plate 100 via a pin or similar means. When it is necessary to measure the depth of the tobacco indentation, simply insert the measuring scale 300 into the opening of the cigarette paper away from the filter tip, and then measure the length between the end face of the tobacco and the end face of the opening in the cigarette paper. This determines whether the process requirements are met, thus enabling the measurement of the tobacco indentation depth. It should be noted that, in order to allow for flexible measurement by reaching deep into the tobacco end of the cigarette, the measuring end of the measuring scale 300 has a circular cross-section, and its diameter should be smaller than the radius of the cigarette cross-section.

[0042] In this embodiment, in order to prevent the plate 100 from rusting and to ensure that the scale values ​​are clearly visible, the plate 100 can be made of stainless steel. The surface does not need to be painted or electroplated, and it is smooth, not easy to get dirty, and easy to clean.

[0043] In some specific embodiments, the number of measuring holes 110 is N, satisfying: N≥1, and a ring 111 is fitted in the measuring hole 110, the ring 111 having a hole D of a preset diameter.

[0044] Please see Figure 1 and Figure 2 As shown, in this embodiment, in order to accurately inspect and measure the diameter of the cigarette, multiple measuring holes 110 are opened on the first surface, and then a ring 111 is embedded in each measuring hole 110. The diameter of the ring 111 at different positions is different. In this embodiment, there are three rings 111, which are spaced apart along the height direction. The uppermost ring 111 has the largest hole diameter, the middle ring 111 has the second largest hole diameter, and the lowermost ring 111 has the smallest hole diameter. The cigarette is tested by passing through the holes of the three rings 111 to determine whether the diameter of the cigarette is within the corresponding diameter range, thereby determining whether the diameter of the cigarette meets the process requirements.

[0045] For example, in this embodiment, the inner circumference of the uppermost ring 111 is 24.5 mm, the inner circumference of the middle ring 111 is 24.3 mm, and the inner circumference of the lowermost ring 111 is 24.1 mm. In practice, the size of the aperture D can be adjusted according to the diameter of cigarettes of different specifications and brands to adjust the inner circumference of the ring 111. The specific value of the aperture D is not limited here.

[0046] In some specific embodiments, the placement groove 120 includes a first groove 121 and a second groove 122 formed on a first side surface, and the first groove 121 and the second groove 122 have a semi-circular cross section.

[0047] Please see Figure 1 and Figure 2As shown, in this embodiment, cigarettes are placed sequentially in the first groove 121 or the second groove 122. The position of the cigarette mark and the length of the filter tip tip at the gradation line 200 are observed for inspection and measurement. It should be noted that in order to accommodate the placement of cigarettes, the cross-sectional shape of the first groove 121 and the second groove 122 are both semi-circular, allowing the cigarettes to be placed inside from the opening on the first side. This facilitates the placement of the cigarettes inside and their rotation during the inspection process. The position of the cigarette mark and the length of the filter tip tip are then observed and judged through the gradation line 200.

[0048] In other embodiments, the cross-sectional shape of the first groove 121 and the second groove 122 may be larger than half a circle, and the cigarette can be placed inside the axial end openings of the first groove 121 and the second groove 122.

[0049] In this embodiment, the ends of the first groove 121 and the second groove 122 are both connected to the outside of the plate 100.

[0050] In some specific embodiments, the graduation line 200 includes a first graduation line 210, a second graduation line 220, and a third graduation line 230 disposed on a first side surface. The first graduation line 210 is located on one side of the first groove 121 in the radial direction, and the second graduation line 220 and the third graduation line 230 are respectively located on both sides of the second groove 122 in the radial direction. The first graduation line 210 is provided with at least one first detection area 211; the second graduation line 220 is provided with at least one second detection area 221 and at least one third detection area 222; and the third graduation line 230 is provided with at least one fourth detection area 231.

[0051] In this embodiment, since the cigarettes have cigarette markings, the markings are detected by placing the cigarettes in the first groove 121. For example, three types of cigarettes are used as examples: cigarettes A, cigarettes B, and cigarettes C. Different methods are used to detect the markings of different types of cigarettes. When detecting cigarette A, cigarette A is placed in the first groove 121 with the filter end facing upwards, and then it is observed whether the upper edge of the marking of cigarette A is located in the first detection area 211. When it is necessary to detect the marking of cigarette B, cigarette B can be placed in the second groove 122 with the tobacco end facing upwards, and it is observed whether the upper edge of the marking of cigarette B is located in the second detection area 221. When it is necessary to detect the marking of cigarette C, the filter end is placed in the second groove 122, and it is observed whether the upper edge of the marking of cigarette C is located in the fourth detection area 231.

[0052] Furthermore, in order to accommodate the detection of cigarette markings for different specifications and models of cigarettes, multiple corresponding first detection areas 211 can be set on the first scale line 210, multiple corresponding second detection areas 221 can be set on the second scale line 220, and multiple fourth detection areas 231 can be set on the third scale line 230, depending on the specifications of the cigarettes. The number of first detection areas 211, second detection areas 221, and fourth detection areas 231 is not limited.

[0053] In this embodiment, by placing the cigarette in the second groove 122 and detecting the lower edge of the splicing paper, at least one third detection area 222 is also provided on the second scale line 220. Specifically, the cigarette filter end is placed in the second groove 122 with the other end facing up, and it is observed whether the lower edge of the splicing paper is located in the third detection area 222, so as to determine whether the length of the splicing device meets the requirements.

[0054] Since it is necessary to detect the length of the tipping paper of other cigarette specifications in the second groove 122, multiple corresponding third detection areas 222 can be set on the second scale line 220 to detect the length of the tipping paper of different cigarette specifications and models, thus satisfying the requirement for detecting the length of the tipping paper of different cigarette specifications.

[0055] In some specific embodiments, the plate 100 also has a third side surface 103, and a receiving groove 130 is provided on the first side surface. The receiving groove 130 communicates with the outside of the plate 100 facing the third side surface. The third side surface has a first limiting surface 131. A limiting groove 140 is provided on the third side surface at the location of the receiving groove 130. The limiting groove 140 has a second limiting surface 141. A preset distance L is formed between the first limiting surface 131 and the second limiting surface 141.

[0056] Please see Figure 1 and Figure 2 as well as Figure 3 As shown, in order to detect the overall length of the cigarette, a limiting groove 140 is formed on the upper surface of the plate 100 at the position of the receiving groove 130. The second limiting surface 141 is the bottom surface of the limiting groove 140, and the first limiting surface 131 is the third side surface of the plate 100 in the width area of ​​the receiving groove 130. That is, the first limiting surface 131 is located on the upper surface of the plate 100, and a preset distance L is formed between the first limiting surface 131 and the second limiting surface 141. It should be noted that when it is necessary to detect the length of the cigarette, the filter end can be placed vertically into the receiving groove 130 with the filter end facing upward, and then it is observed whether the filter end face exceeds the first limiting surface 131. If it does, it is determined that the length of the cigarette is too large. If it does not, the cigarette is rolled in the receiving groove 130 to move it to the position of the second limiting surface 141, and then it is observed whether the filter end is lower than the second limiting surface 141. If it does, it is determined that the length of the cigarette is too small. If it does not, it is determined that the length of the cigarette is qualified.

[0057] In some specific embodiments, a mounting groove 150 is provided on the second side, and a first connecting hole 151 is provided on the first side through the mounting groove 150. A screwing component 160 is installed in the first connecting hole 151, and the screwing component 160 passes through the first connecting hole 151 and the measuring ruler 300.

[0058] See Figure 2 and Figure 4 As shown, in order to enable the measuring scale 300 to be rotatably mounted on the plate 100, a mounting groove 150 is provided on the second side of the plate 100. The measuring scale 300 is mounted on the plate 100 by means of a screwing member 160 passing through the mounting groove 150 and the measuring scale 300.

[0059] In this embodiment, the screwing component 160 can be a bolt or a pin that allows the measuring scale 300 to be rotated and mounted on the plate 100.

[0060] In some specific embodiments, the measuring ruler 300 includes a mounting member 310 and a ruler body 320. The ruler body 320 is integrally or detachably mounted on the mounting member 310, and a fourth scale line 321 is provided on the end surface of the ruler body 320 facing away from the mounting member 310.

[0061] Please see Figure 1 and Figure 5 As shown, in this embodiment, the ruler 320 has a circular cross-section. When it is necessary to detect the depth of the tobacco shreds, the ruler 320 can be inserted into the interior of the tobacco shred end of the cigarette, and then the ruler 320 can be made to abut against the tobacco shred end face. The position of the cigarette paper end at the fourth scale line 321 can be observed to determine the depth of the tobacco shreds and realize the detection of the depth of the tobacco shreds.

[0062] In some specific embodiments, the mounting component 310 is provided with a second connecting hole 311 that passes through it, the end face of the mounting component 310 is provided with a sleeve hole 312, the ruler body 320 is disposed in the sleeve hole 312, the side of the mounting component 310 is provided with a mounting hole 313, and an abutting component 330 that abuts against the ruler body 320 is installed in the mounting hole 313.

[0063] In order to enable the entire measuring scale 300 to be rotatably mounted on the plate 100, a second connecting hole 311 is made through the mounting member 310. The screwing member 160 passes through the mounting groove 150 and the second connecting hole 311 to rotatably mount the mounting member 310 on the plate 100. Furthermore, the mounting member 310 and the ruler 320 can be hidden in the mounting groove 150. Specifically, the ruler 320 extends into the sleeve hole 312. In order to prevent the ruler 320 from falling out of the sleeve hole 312, an abutment member 330 is installed in the mounting hole 313 on the side of the mounting member 310. The abutment member 330 abuts against the surface of the ruler 320 in the mounting hole 313, thereby fixing the position of the ruler 320 and preventing the ruler 320 from falling out of the sleeve hole 312.

[0064] For example, the mounting hole 313 can be a threaded hole, and the abutment 330 can be a screw, bolt or other threaded screw 160. The abutment 330 can be threaded with the mounting hole 313 and abut against the surface of the ruler 320 during the screwing process to fix its position.

[0065] Understandably, if the cigarette paper has defects such as yellow spots, stains, or damage, it can still be measured using a ruler 320.

[0066] In some specific embodiments, since the mounting member 310 and the ruler body 320 are hidden in the mounting groove 150 when not in use, in order to facilitate the ruler body 320 to rotate out of the mounting groove 150 for use, an extension block 340 is provided at the end of the mounting member 310 away from the ruler body 320. By moving the extension block 340, the ruler body 320 can be rotated around the screwing member 160 to the outside of the mounting groove 150, thereby facilitating use.
