[0002] In the process of producing cigarettes, cigarette factories need to randomly inspect cigarette samples to detect the moisture content and other component indicators of tobacco and the ratio indicators of different tobacco structures. At present, during the inspection, the tobacco and cigarette paper in the cigarette should be separated. The separation method is to first use a machine to cut the cigarette longitudinally, so that multiple longitudinal cuts are produced on the cigarette, and then send the longitudinally cut cigarettes to a vibrating screen and other devices for vibration screening to separate the tobacco and cigarette paper. However, it is found in actual operation that the separation between tobacco and cigarette paper is not thorough enough during vibration screening. Since all tobacco cannot be completely separated from the cigarette paper, the inspection of tobacco cannot accurately reflect the ratio indicators of the overall tobacco structure. If the tobacco remaining in the cigarette paper is subsequently separated manually, it will affect the efficiency of the entire inspection process and increase the overall time consumption of the inspection process.

[0023] 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.
[0024] like Figure 1-Figure 4 As shown, the embodiment of the present application provides a cigarette tobacco and cigarette paper separator, which is applied to the process of tobacco detection in cigarettes in a cigarette factory. During the production process of the cigarette factory production line, the tobacco in the cigarettes is sampled and tested for indicators such as moisture index and the ratio of different tobacco structures. After sampling the cigarettes, the cigarettes are first cut longitudinally by a machine, and the cigarettes are longitudinally cut on the outer surface of the cigarettes in a plane perpendicular to the axial direction of the cigarettes. The longitudinal cuts are made multiple times along the axial direction of the cigarettes, and then the longitudinally cut cigarettes are sent to a device such as a vibrating screen for vibration screening, so that the tobacco and cigarette paper in the cigarettes are separated from each other. However, it was found in actual operation that when the longitudinally cut cigarettes were vibrated and screened, the tobacco in the cigarette paper was not separated thoroughly enough, and the problem of tobacco residue often occurred, and the tobacco could not be completely separated, so that the sample test results could not truly reflect the indicators in the tobacco. The detection structure was not accurate enough. If the authenticity and accuracy of the test results are to be ensured, the tobacco residue in the cigarette paper needs to be manually separated again. This requires more manpower, increases the time consumption of the detection process, and is not conducive to improving the detection efficiency. The separator of the present application aims to improve the separation rate of tobacco and cigarette paper to avoid the above-mentioned problems.
[0025] The cigarette tobacco and paper separator comprises a material channel, a first roller 100 and a second roller 200, the material channel has a feed end and a discharge end, the first roller 100 and the second roller 200 are both cylindrical structures, the first roller 100 and the second roller 200 are axially parallel and spaced apart, there is a gap between the first roller 100 and the second roller 200, the gap at least constitutes a part of the material channel, and the circumferential rotation speed of the second roller 200 is greater than the axial rotation speed of the first roller 100, the material enters the material channel from the feed end of the material channel, and then moves along the material channel to the discharge end of the material channel, and is discharged through the discharge end of the material channel, during which the rotation direction of the second roller 200 on the side close to the first roller 100 is It is the direction from the feed end to the discharge end on the material channel path, that is, the rotation direction of the second roller 200 on the side close to the first roller 100 is the direction of the material moving toward the discharge end in the material channel. Preferably, the material channel is used to transport the cigarettes after longitudinal cutting, and the gap between the outer surface of the first roller 100 and the outer surface of the second roller 200 is slightly smaller than the diameter of the cigarette. Preferably, the difference between the gap between the outer surface of the first roller 100 and the outer surface of the second roller 200 and the diameter of the cigarette to be processed is 1-3 mm. Under the action of the difference in rotation speed between the first roller 100 and the second roller 200, the cigarettes are rubbed and crushed, so that the cigarette paper can be further broken, and the tobacco is loosened to a certain extent, which is more conducive to the mutual separation of tobacco and cigarette paper during subsequent vibration screening.
[0026] Preferably, the separator further comprises a shell 3, the first roller 100 and the second roller 200 are both arranged in the shell 3, a feed port is arranged at the upper part of the shell 3, a discharge port is arranged at the lower part of the shell 3, and a material channel is formed along the path from the feed port to the gap between the first roller 100 and the second roller 200 and then to the discharge port in the shell 3. In this embodiment, the shell 3 is a square box structure with an opening on one side. When the shell 3 is upright, the front opening of the shell 3 is used as an example for explanation, and the rear side, left side, right side, top side and bottom side of the shell 3 are all For the plate structure enclosure, the first roller 100 and the second roller 200 are both arranged on the rear side of the shell 3 through a rotating shaft, and the axis of the rotating shaft is arranged perpendicular to the rear side of the shell 3. Preferably, the rotating shafts of the first roller 100 and the second roller 200 can be connected to their respective adjustment seats through bearings respectively, and the adjustment seats are not shown in the figure. A waist-shaped groove is arranged on the rear side of the shell 3, and the adjustment seat can be adjusted in the waist-shaped groove, and then the size of the gap between the first roller 100 and the second roller 200 can be adjusted by changing the position of the adjustment seat to adapt to cigarettes of different sizes.
[0027] In this embodiment, a driving motor may be arranged on the adjusting seat, and the output end of the driving motor is connected to the corresponding rotating shaft, thereby driving the first roller 100 and the second roller 200 to rotate respectively.
[0028] In this embodiment, a window 301 may be provided on the right side of the shell 3 near the top. The window 301 constitutes a feed port of the shell 3 , and cigarettes are fed into the shell 3 through the window 301 .
[0029] In this embodiment, the axis height of the first roller 100 is higher than the axis height of the second roller 200, and the difference between the outer diameter of the first roller 100 and the outer diameter of the second roller 200 is not higher than three times the smaller outer diameter of the two. Preferably, the outer diameter of the first roller 100 and the outer diameter of the second roller 200 are equal, and the axis of the first roller 100 and the axis of the second roller 200 form an angle of 45 degrees with the horizontal plane. In one example, the first roller 100 is closer to the left side and the top side of the shell 3, and the second roller 200 is closer to the right side and the bottom side of the shell 3. At this time, the lower part of the space between the second roller 200 and the left side is opened to form a discharge port in the shell 3.
[0030] Preferably, the circumferential rotation speed of the first roller 100 is greater than zero, that is, the linear speed of the first roller 100 is greater than zero, and the linear speed of the second roller 200 is greater than the linear speed of the first roller 100. In one example, when facing the front opening of the shell 3, the rotation directions of the first roller 100 and the second roller 200 are both counterclockwise. Therefore, the linear speeds of the first roller 100 and the second roller 200 are in opposite directions at the position where they are close to each other, thereby increasing the rubbing effect on the cigarette, which is more conducive to the separation of cigarette paper and tobacco during subsequent vibration screening.
[0031] Preferably, an axial groove may be provided on the outer circumferential surface of the first roller 100 and / or an axial groove may be provided on the outer circumferential surface of the second roller 200. The axial groove may be provided only on the outer circumferential surface of the first roller 100, or only on the outer circumferential surface of the second roller 200, or both of the first roller 100 and the second roller 200 may be provided with axial grooves, the grooves are concave in the outer circumferential surface, and the radial depth of the concave is 1-3 mm. When the first roller 100 and the second roller 200 cooperate to roll and grind the cigarette, the rolling effect on the cigarette is improved, and it is more conducive to loosening the cigarette paper and the tobacco. Taking the arrangement of the grooves on the outer circumferential surface of the second roller 200 as an example, the length direction of the grooves is parallel to the length direction of the second roller 200, and the length of the grooves runs through the axial length of the second roller 200. There are multiple grooves and they are evenly spaced along the circumferential direction of the outer surface of the second roller 200.
[0032] Regarding the outer circumferential surface of the first roller 100 and the second roller 200, in another example, the outer circumferential surface of the first roller 100 and / or the second roller 200 is continuously wavy in the circumferential direction, the wave crests and troughs are smoother, and the radius difference between the crests and the troughs is less than 3 mm, which is beneficial to improve the looseness of the rolled cigarettes and reduce unnecessary serious damage to the tobacco, thereby improving the rolling effect of the cigarettes.
[0033] In the cigarette paper sampling and testing process, the separator is used to further process the longitudinally cut cigarettes, and then send the cigarettes processed by the separator to a vibrating screen and other equipment for vibration screening. After further rolling and loosening by the separator, the separation between tobacco and cigarette paper is more thorough during vibration screening. For this reason, preferably, the vibration screening device 4 can also be arranged in the shell 3 to improve the integration of the equipment and avoid setting too many conveying equipment in the middle. In one example, the vibration screening device 4 is arranged inside the shell 3 and below the discharge port of the shell 3, that is, the vibration screening device 4 is horizontally arranged below the second roller 200. More preferably, a material box 6 is arranged inside the shell 3 and below the vibration screening device 4. The material box 6 is used to collect tobacco screened by the vibration screening device 4. In some examples, the vibration screening device 4 is arranged in the shell 3 and below the second roller 200. A blocking block 5 is arranged on the left side of the shell 3. The lower opening between the blocking block 5 and the second roller 200 and the shell 3 constitute The top of the blocking block 5 extends to the first roller 100, and the top of the blocking block 5 is an arcuate surface adapted to the first roller 100. The gap between the arcuate surface and the first roller 100 is smaller than the outer diameter of the cigarette to be processed. The gap is preferably 1-2 mm, which can block the cigarettes and prevent them from entering the gap, ensuring that all cigarettes fall down onto the vibrating screening device 4. The vibrating screening device 4 is described as a vibrating screen. The screen of the vibrating screen is located between the first roller 100 and the blocking block 5. Below the block 5, the cigarette passes through the gap between the first roller 100 and the second roller 200, then enters the gap between the blocking block 5 and the second roller 200, and then falls downward onto the screen of the vibrating screen. The material box 6 is arranged below the screen of the vibrating screen. After screening, the tobacco falls downward into the material box 6, and the cigarette paper remains on the screen of the vibrating screen. Preferably, the material box 6 is an independent box body structure, and there is an accommodating space between the screen of the vibrating screen and the bottom side of the shell 3. The accommodating space is used for the material box 6 to enter or be pulled out, so that it is convenient to operate and take out materials.
[0034] In some embodiments, a material guide track 7 is provided above the second roller 200 in the housing 3, and the material at the feed port is transferred to the gap between the first roller 100 and the second roller 200 via the material guide track 7. That is, the cigarette to be processed enters the material guide track 7 via the window 301 on the right side of the housing 3, and then the cigarette is transferred to the gap between the first roller 100 and the second roller 200 via the material guide track 7 for rubbing and grinding. Preferably, the cigarette entering through the window 301 can be freely slid into the gap between the first roller 100 and the second roller 200 via the material guide track 7. The guide track 7 has an inclined top surface, and the top surface of the guide track 7 is inclined downwardly along the direction from the window 301 to the gap between the first roller 100 and the second roller 200. The cigarette entering the shell 3 through the window 301 falls on the top surface of the guide track 7, and then slides downwardly along the top surface of the guide track 7 to the gap between the first roller 100 and the second roller 200. In this way, the structure is simple, which is conducive to reducing the equipment cost. In this embodiment, a blocking plate 8 can also be set above the guide track 7 in the shell 3, and the blocking plate 8 and the guide track A gap is formed between the rails 7 for cigarettes to pass through. Preferably, the top of the blocking plate 8 is connected to the top side of the shell 3, and the bottom of the blocking plate 8 extends toward the material guide rail 7. The distance between the bottom of the blocking plate 8 and the material guide rail 7 is 1-3 times the outer diameter of the cigarette. The length direction of the blocking plate 8 is parallel to the axial direction of the second roller 200. In the horizontal left-right projection, the projection of the blocking plate 8 blocks the upper part of the projection of the window 301, and the upper and lower widths of the exposed lower part of the projection of the window 301 are 1-3 times the outer diameter of the cigarette, and the distance between the blocking plate 8 and the right side of the shell 3 is 1-3 times the outer diameter of the cigarette. The distance between the two rollers is greater than the length of the cigarette. When the cigarette enters the shell 3 through the window 301 and falls onto the guide track 7, the blocking plate 8 and the top of the guide track 7 cooperate with each other to straighten the cigarette and tend to remain parallel to the axis of the second roller 200. Furthermore, in the process of the cigarette continuing to slide down along the guide track 7, it is more conducive to the straightening of the cigarette. The cigarette entering the gap between the first roller 100 and the second roller 200 is better rubbed and crushed, which is more conducive to loosening the cigarette after longitudinal cutting. During the subsequent vibration screening, the separation of tobacco and cigarette paper is more thorough.
[0035] More preferably, a door panel 9 can be provided on the front side of the shell 3. The door panel 9 can be hinged on one side of the shell 3. The door panel 9 can close or open the front side of the shell 3 to prevent cigarettes from falling during handling. The lower side of the door panel 9 does not extend to the bottom side of the shell 3 but extends to the top of the material box 6. When the door panel 9 and the outer side of the material box 6 are aligned, the front side of the shell 3 can be blocked, which makes it more convenient to draw out the material box 6.
[0036] The working principle of the present application is as follows: the driving motor is started to rotate the first roller 100 and the second roller 200. After the longitudinal cutting of the cigarettes by the previous process is completed, the longitudinally cut cigarettes are transported to the guide track 7 in the shell 3 through the window 301. The cigarettes slide down along the guide track 7 to the gap between the first roller 100 and the second roller 200. Under the rotation of the first roller 100 and the second roller 200, the cigarettes are rubbed and loosened, and then fall down on the screen of the vibrating screen. After vibration screening, the tobacco shreds fall down into the material box 6, and the cigarette paper remains on the screen. After completion, the material box 6 is pulled out to take out the tobacco shreds.
