[0031] Referring to Figures 1 and 2, Figure 1 shows a front view of a cigarette cutting device in an embodiment of the present application, and Figure 2 is a top view of the cigarette cutting device shown in Figure 1. A cigarette cutting device 100 provided in an embodiment of the present application includes a cigarette bin 10, a roller 20, and a cutting mechanism 30.

[0032] The cigarette cutting device 100 of the embodiment of the present application can be used to cut waste cigarettes, such as double cigarettes, and can also be used to cut other waste cigarettes, or other semi-finished cigarettes, without specific limitation.

[0033] The cigarette storage 10 has a smoke outlet 11 for discharging cigarettes 200. The cigarette storage 10 is a container for holding cigarettes 200. The cigarette storage 10 has a storage chamber 12, the interior of the storage chamber 12 is used to store cigarettes 200, and the storage chamber 12 is connected to the smoke outlet 11.

[0034] In an embodiment of the present application, the cigarette bin 10 may be roughly in the shape of a funnel with a thick top and a thin bottom, and the smoke outlet 11 is usually arranged at the bottom of the cigarette bin 10 .

[0035] The roller 20 is rotatable relative to the cigarette bin 10 , and a plurality of bearing grooves 21 are sequentially provided on the outer circumferential surface of the roller 20 along the circumferential direction, and the bearing grooves 21 are used to bear the cigarettes 200 .

[0036] The roller 20 can be used as a transport mechanism for the cigarettes 200. When the cigarettes 200 are placed in the carrying groove 21, the roller 20 can be rotated to allow the cigarettes 200 to be transported.

[0037] The shape of the loading slot 21 can be X-shaped, U-shaped or arc-shaped, which can be matched according to different types of cigarettes 200. Usually, each loading slot 21 can only carry one cigarette 200, and in some cases, each loading slot 21 can also carry two or three cigarettes 200.

[0038] The extension direction of the bearing groove 21 can be parallel to the axial direction of the roller 20, or it can be inclined relative to the axial direction of the roller 20. However, this may increase the risk of the cigarette 200 falling into the bearing groove 21 during the rotation of the roller 20. If a blocking structure is provided at the end of the bearing groove 21 to prevent the cigarette 200 from falling or a rough portion that can increase the friction is provided in the bearing groove 21, the manufacturing difficulty of the roller 20 will be increased. Therefore, it is a preferred solution that the extension direction of the bearing groove 21 is parallel to the axial direction of the roller 20.

[0039] The length of the carrying groove 21 is greater than the length of the cigarette 200, and the diameter of the carrying groove 21 is greater than the diameter of the cigarette 200. These settings are conducive to the carrying groove 21 to smoothly carry the cigarette 200.

[0040] The roller 20 further includes a cutting groove 22 , which is connected to the bearing groove 21 and is used to divide the bearing groove 21 along the extending direction of the bearing groove 21 .

[0041] Splitting the carrying groove 21 refers to a structure in which the carrying groove 21 is divided into multiple sections along the extending direction of the carrying groove 21. In other words, each section of the divided carrying groove 21 can carry a portion of the cigarette 200.

[0042] The cutting mechanism 30 is connected to the roller 20 , and can extend into the cutting groove 22 to cut the cigarettes 200 .

[0043] The cutting mechanism 30 is a mechanism capable of cutting the cigarette 200 into multiple sections. The cutting mechanism 30 may include a cutting knife 31 or a cutting line.

[0044] Therefore, in the cigarette cutting device 100 of the embodiment of the present application, after the carrying groove 21 on the roller 20 carries the cigarettes 200 discharged from the cigarette storage 10, since the roller 20 is also provided with a cutting groove 22 for dividing the carrying groove 21, during the process of the roller 20 conveying the cigarettes 200, the cutting mechanism 30 can extend into the cutting groove 22 to cut the cigarettes 200 carried on the carrying groove 21. The cigarettes 200 can be cut into multiple sections in the carrying groove 21 to become standard cigarettes, and then the standard cigarettes can be recycled in a non-beating manner, thereby improving the whole tobacco rate, and the tobacco does not need to be downgraded, thereby reducing the waste of tobacco.

[0045] Specifically in the embodiment of the present application, the cigarette bin 10 is a vibrating cigarette bin.

[0046] By means of vibration, the cigarettes 200 in the cigarette bin 10 can be uniformly discharged from the cigarette outlet 11 , thereby facilitating the bearing groove 21 of the roller 20 to receive the cigarettes 200 .

[0047] In some embodiments, the cigarette cutting device 100 further includes a cigarette conveying mechanism 40 , which is connected between the roller 20 and the smoke outlet 11 and is used to convey the cigarettes 200 discharged from the smoke outlet 11 to the roller 20 .

[0048] By providing the cigarette delivery mechanism 40 , the success rate of the cigarette 200 entering the bearing groove 21 of the roller 20 can be increased.

[0049] Specifically, the cigarette conveying mechanism 40 includes a cigarette conveying belt 41 . In the vertical direction, the cigarette conveying belt 41 is arranged to be tilted downward from the cigarette outlet 11 toward the roller 20 to convey the cigarettes 200 .

[0050] By arranging the cigarette conveying belt 41 to be inclined downward from the smoke outlet 11 toward the roller 20 , it is more convenient to convey the cigarettes 200 into the bearing groove 21 of the roller 20 .

[0051] It should be pointed out here that the opening direction of the bearing slot 21 of the roller 20 is consistent with the rotation direction of the roller 20 . When the roller 20 rotates, the bearing slot 21 can smoothly obtain the cigarettes 200 on the cigarette conveying belt 41 .

[0052] In other embodiments, the cigarette delivery mechanism 40 may be omitted, and a blocking plate may be provided between the smoke outlet 11 and the roller 20 to form a material taking area to facilitate the bearing groove 21 of the roller 20 to take the cigarettes 200 .

[0053] In an embodiment of the present application, the dividing groove 22 includes at least one, each dividing groove 22 is connected to each bearing groove 21, and all the dividing grooves 22 are spaced apart from each other along the extension direction of the bearing groove 21, so as to divide each bearing groove 21 into at least two sections.

[0054] Specifically in the embodiment of the present application, the dividing groove 22 includes one, and the dividing groove 22 is used to divide the bearing groove 21 into two halves along the extension direction of the bearing groove 21 .

[0055] In this way, when the cigarette 200 is a double cigarette, the cigarette 200 can be divided into two halves to form a standard cigarette.

[0056] In some embodiments, the slitting groove 22 is an annular groove surrounding the rotation axis of the roller 20, the top of the slitting groove 22 extends to the outer peripheral surface of the roller 20, and the bottom of the slitting groove 22 extends at least to the bottom of the bearing groove 21, for example, extends to the rotating shaft of the roller 20, without specific limitation.

[0057] By setting the slitting groove 22 as an annular groove surrounding the rotation axis of the roller 20, on the one hand, the slitting groove 22 of each bearing groove 21 is evenly arranged, thereby improving the uniformity of the length of the cigarettes 200 after slitting. On the other hand, the structure of the annular groove is simple, which is conducive to the manufacture of the roller 20, reduces the manufacturing difficulty, and saves the manufacturing cost.

[0058] In some embodiments, the slitting mechanism 30 includes a rotatable slitting knife 31 , and the rotation direction of the slitting knife 31 is the same as the rotation direction of the roller 20 .

[0059] Specifically in the embodiment of the present application, the roller 20 rotates counterclockwise as shown in FIG. 1 , and the slitting knife 31 also rotates counterclockwise as shown in FIG. 1 .

[0060] It should be pointed out here that the rotation axis of the slitting knife 31 is parallel to the rotation axis of the roller 20 .

[0061] Optionally, the slitting knife 31 comprises a disc slitting knife. The disc slitting knife has blades all around its outer circumference, so that during the rotation of the roller 20, it can always extend into the slitting groove 22 to perform slitting operations on the cigarettes 200, thereby improving the efficiency of slitting the cigarettes 200.

[0062] In some embodiments, the cigarette cutting device 100 further includes a plurality of conveying mechanisms 50 , each conveying mechanism 50 corresponding to each divided carrying slot 21 , and used for conveying the cut cigarettes 200 .

[0063] Specifically, when the carrying groove 21 divided by the cutting groove 22 includes two sections, the conveying mechanism 50 includes two, one conveying mechanism 50 corresponds to one section of the divided carrying groove 21 to convey the cut cigarettes 200 in the section of the carrying groove 21, and the other conveying mechanism 50 corresponds to the other section of the divided carrying groove 21 to convey the remaining cut cigarettes 200 in the section of the carrying groove 21.

[0064] By providing independent conveying mechanisms 50 to convey the cut cigarettes 200 respectively, the cut cigarettes 200 will not be confused or damaged by collision during the conveying process, thereby affecting the subsequent recovery, and the conveying efficiency is improved.

[0065] In an embodiment of the present application, the conveying mechanism 50 includes a conveying belt 51 , which covers a portion of the outer peripheral surface of the roller 20 along the circumference of the roller 20 to form a conveying channel for conveying cigarettes 200 between the roller 20 and the conveying belt 51 .

[0066] By arranging a conveying belt 51 to cover a portion of the outer peripheral surface of the roller 20 along the circumference of the roller 20 to form a conveying channel, the cut cigarettes 200 unloaded from the roller 20 can be received more smoothly and the cut cigarettes 200 can be conveyed in an orderly manner.

[0067] Specifically, the conveying mechanism 50 also includes multiple conveying wheels 52, and the conveying belt 51 is wound around the outside of all the conveying wheels 52, wherein two conveying wheels 52 are arranged opposite to each other along the radial direction of the roller 20, and the conveying belt 51 passes through the two conveying wheels 52 to half-cover a portion of the outer peripheral surface of the roller 20 along the circumference of the roller 20.

[0068] It should be noted here that in order not to affect the cigarette conveying mechanism 40 conveying cigarettes 200 to the roller 20 , the position where the conveying belt 51 covers the roller 20 does not overlap with the connection position between the cigarette conveying mechanism 40 and the roller 20 .

[0069] In an embodiment of the present application, the cigarette cutting device 100 also includes a cigarette collecting mechanism 60, which is distributed on both sides of the axial direction of the roller 20 and is located upstream of the cutting mechanism 30 along the rotation direction of the roller 20, and is used to push the part of the cigarette 200 protruding outside the supporting groove 21 into the supporting groove 21.

[0070] In this way, the positions of the cigarettes 200 dropped into each of the loading slots 21 can be made substantially the same, so that after the cigarettes 200 are cut by the cutting mechanism 30 , the cut cigarettes 200 have uniform sizes.

[0071] Specifically, the cigarette collecting mechanism 60 can move relative to the rotating roller 20 to push the portion of the cigarette 200 protruding outside the bearing slot 21 into the bearing slot 21 during the movement.

[0072] More specifically, the smoke collecting mechanism 60 includes at least two smoke collecting wheels 61, all of which are distributed on both sides of the axial direction of the roller 20, and the rotation axis of each smoke collecting wheel 61 is perpendicular to the rotation axis of the roller 20. The rotation directions of the smoke collecting wheels 61 distributed on both sides of the axial direction are opposite, and the smoke collecting wheels 61 are used to push the part of the cigarette 200 protruding outside the supporting groove 21 into the supporting groove 21 during the rotation process.

[0073] As shown in Figure 1, the cigarette collecting wheel 61 is located above the slitting mechanism 30. As can be seen from Figure 2, the upper cigarette collecting wheel 61 rotates clockwise, the lower cigarette collecting wheel 61 rotates counterclockwise, and the roller 20 rotates to the left. In other words, both the upper cigarette collecting wheel 61 and the lower cigarette collecting wheel 61 push the cigarettes 200 along the rotation direction of the roller 20. In this way, the cigarette collecting wheel 61 will not form resistance to the cigarettes 200 on the roller 20, and it is beneficial for the cigarettes 200 to be smoothly pushed into the carrying groove 21.

[0074] In other embodiments, the cigarette collecting mechanism 60 may also remain stationary relative to the rotating roller 20 so as to push the portion of the cigarette 200 protruding outside the loading slot 21 into the loading slot 21 by blocking.

[0075] Based on the same inventive concept, the present application also provides a cigarette recovery system, including the cigarette cutting device 100 in any of the above embodiments.

[0076] Furthermore, the cigarette recovery system also includes an air-blowing waste cigarette processing mechanism, and the cigarette cutting device 100 is connected to the air-blowing waste cigarette processing mechanism. The air-blowing waste cigarette processing mechanism is used to receive the cigarettes 200 cut from the cigarette cutting device 100 and recover the cut cigarettes 200.

[0077] The air-blowing waste cigarette processing mechanism referred to here can specifically perform an air-blowing operation on the cut cigarettes 200 to separate the tobacco shreds in the cigarettes 200 from the cigarettes 200 , so as to facilitate the recovery of the tobacco shreds.

[0078] Specifically, the air-blowing waste cigarette processing mechanism includes a kneading mechanism and a blowing mechanism. The kneading mechanism is used to knead the cut cigarette 200 so that the tobacco shreds can be looser in the wrapping paper and facilitate the subsequent blowing operation. The blowing mechanism can blow air into the kneaded cigarette to blow the tobacco shreds out of the cigarette. Specifically, the blowing mechanism includes a blowing nozzle, which is connected to one end of the cigarette, specifically, the filter end of the cigarette.

[0079] In the cigarette recovery system of the embodiment of the present application, after the carrying groove 21 on the roller 20 carries the cigarettes 200 discharged from the cigarette storage 10, since the roller 20 is also provided with a cutting groove 22 for dividing the carrying groove 21, during the process of the roller 20 conveying the cigarettes 200, the cutting mechanism 30 can extend into the cutting groove 22 to cut the cigarettes 200 carried on the carrying groove 21. The cigarettes 200 can be cut into multiple sections in the carrying groove 21 to become standard cigarettes, and then the standard cigarettes can be recycled in a non-beating manner, thereby improving the whole tobacco rate, and the tobacco does not need to be downgraded, thereby reducing the waste of tobacco.

[0080] In order to more clearly understand the working principle of the cigarette cutting device 100 of the embodiment of the present application, the cutting process of double cigarettes in the cigarette cutting device 100 is described in detail below:

[0081] 1. First, manually arrange the double-sized cigarettes neatly and stack them on a loading tray, then mount the loading tray on the upper part of the cigarette bin 10 with the opening of the loading tray facing downward, and load the double-sized cigarettes into the cigarette bin 10.

[0082] 2. The cigarette bin 10 is continuously vibrated driven by the motor and the eccentric mechanism, and the doubled cigarettes stacked in the cigarette bin 10 are released downward and fall into the cigarette taking area from the cigarette outlet 11.

[0083] 3. The cigarette conveying belt 41 rotates continuously, and its running direction is toward the roller 20 . The cigarette conveying belt 41 forms a downward inclined surface with a certain angle near the roller 20 , which is conducive to conveying double cigarettes into the bearing groove 21 of the roller 20 .

[0084] 4. The roller 20 rotates counterclockwise, and the opening direction of the bearing groove 21 on the roller 20 is consistent with the rotation direction of the roller 20. When the roller 20 rotates, the bearing groove 21 grabs double cigarettes in the cigarette taking area.

[0085] 5. When the bearing slot 21 with double cigarettes moves to the position of the cutting knife 31, the double cigarettes are cut from the middle under the high-speed rotation of the cutting knife 31 to form two separate standard cigarettes.

[0086] 6. The two standard cigarettes are wrapped and conveyed by the two conveyor belts 51 and enter the cigarette release area for release. The released standard cigarettes are collected by a collection bucket or other collection devices and finally poured into the air-blowing waste cigarette processing mechanism for recycling.

[0087] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0088] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
