[0037] The technical solutions in the embodiments will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figure 1 and Figure 2 As shown, in some embodiments of the cigarette conveying device provided by the present invention, the cigarette conveying device includes a conveying channel 10 and a diverter assembly 20, the conveying channel 10 includes a first conveying section 11 and a second conveying section 12 connected to the first conveying section 11, the diverter assembly 20 is arranged in the second conveying section 12, the diverter assembly 20 is used to separate the second conveying section 12 into relatively independent first channels 121 and second channels 122, and one end of the diverter assembly 20 close to the first conveying section 11 is basically flush with one end of the second conveying section 12 close to the first conveying section 11.

[0040] In the above embodiment, the cigarette conveying device includes a diverter component 20, through which the cigarettes conveyed by the first conveying section 11 can be separated into two channels, so as to avoid squeezing of multiple cigarettes and avoid quality problems such as cigarette contact, cigarette flattening or cigarette wrinkles; moreover, the end of the diverter component 20 close to the first conveying section 11 is basically flush with the end of the second conveying section 12 close to the first conveying section 11, so that the cigarette diversion position and the starting position of the second conveying section 12 can be kept at basically the same height, so that the diverted cigarettes can enter the first channel 121 or the second channel 122 more smoothly, reducing the problem of cigarette squeezing.

[0041] In some embodiments, in the conveying direction of the first conveying section 11, the distance between the end of the diverter assembly 20 close to the first conveying section 11 and the end of the first conveying section 11 close to the second conveying section 12 is adjustable. The advantage of such a configuration is that the relative position between the diverter assembly 20 and the first conveying section 11 can be adjusted at any time as needed, so that the end of the diverter assembly 20 close to the first conveying section 11 and the end of the second conveying section 12 close to the first conveying section 11 are kept as flush as possible.

[0042] In some embodiments, the diverter assembly 20 includes a diverter assembly body and a roller 21 rotatably disposed on the diverter assembly body, and the roller 21 is disposed at an end of the diverter assembly body close to the first conveying section 11 .

[0043] By providing the roller 21, when the cigarette reaches the diversion position, the cigarette can be diverted to the first channel 121 or the second channel 122 by the rotation of the roller 21 relative to the diversion component body, thereby reducing the impact generated when the cigarette contacts the diversion component 20, avoiding the diversion component 20 from damaging the cigarette and affecting the quality of the cigarette.

[0044] like Figure 3 As shown, in some embodiments, the diverter assembly body includes a diverter block 22, a positioning block 23 and a rotating shaft 24, the roller 21 is rotatably mounted on the rotating shaft 24, the rotating shaft 24 is mounted on the positioning block 23, and the positioning block 23 is movably mounted on the diverter block 22 to adjust the distance between the roller 21 and the end of the first conveying section 11 close to the second conveying section 12.

[0045] By movably installing the positioning block 23 on the diverter block 22 , the relative position between the roller 21 and the first conveying section 11 can be adjusted, which is beneficial for keeping the top surface of the roller 21 basically flush with the end of the first conveying section 11 close to the second conveying section 12 .

[0046] In some embodiments, the diverter assembly body also includes a connecting piece, the diverter block 22 is provided with a first connecting hole 221, the positioning block 23 is provided with a second connecting hole 231, the connecting piece passes through the first connecting hole 221 and the second connecting hole 231 to connect the diverter block 22 and the positioning block 23, and the first connecting hole 221 and / or the second connecting hole 231 include a long hole.

[0047] By configuring the first connection hole 221 and / or the second connection hole 231 to include an elongated hole, the relative position between the roller 21 and the first conveying section 11 can be adjusted by adjusting the installation position of the elongated hole.

[0048] In some embodiments, the length direction of the elongated hole is parallel to the conveying direction of the first conveying section 11 .

[0049] In some embodiments, a concave platform 222 is provided on the side of the diverter block 22, and the positioning block 23 is installed on the concave platform 222. The concave platform 222 is provided to facilitate the installation of the positioning block 23. Moreover, the concave platform 222 is concave inward relative to the side of the diverter block 22, thereby forming a step on the side of the diverter block 22, through which the positioning block 23 can be supported, effectively improving the installation stability of the positioning block 23.

[0050] In some embodiments, the width of the diverter block 22 along the first direction gradually increases in the direction away from the first conveying section 11, and the first direction is perpendicular to the conveying direction of the first conveying section 11. This arrangement allows the first channel 121 and the second channel 122 to gradually move away from each other in the direction away from the first conveying section 11, thereby achieving cigarette diversion and reducing the squeezing force on the cigarettes caused by the gravity of the upper layer of cigarettes, thereby preventing the cigarettes from being flattened or wrinkled.

[0051] like Figure 1 and Figure 2 As shown, the longitudinal section of the diverter block 22 is pear-shaped.

[0052] In some embodiments, an arc-shaped groove 223 is provided at the end of the diverter block 22 close to the first conveying section 11, and the groove 223 is used to support the roller 21. By providing the groove 223, the roller 21 can be supported, and the rotation of the roller 21 can be guided and restricted, so as to prevent the roller 21 from deflecting relative to the diverter assembly body and affecting the diverting effect on the cigarettes.

[0053] In some embodiments, both sides of the end of the diverter block 22 away from the first conveying section 11 include arc-shaped transition portions 224. The arc-shaped transition portions 224 are provided to facilitate the cigarettes to slowly converge toward the middle at the end of the second conveying section 12. Moreover, the arc-shaped transition portions can make the cigarettes conveyed more smoothly and avoid collision or squeezing of the cigarettes.

[0054] In some embodiments, the conveying channel 10 includes a third conveying section 13, and the third conveying section 13 is connected to both the first channel 121 and the second channel 122. By providing the third conveying section 13, the diverted cigarettes can be merged together to facilitate subsequent processing operations.

[0055] In some embodiments, the cigarette conveying device further includes a support plate 30 , a first side plate 40 and a second side plate 50 . The first side plate 40 and the second side plate 50 are relatively connected to the support plate 30 , and a conveying channel 10 is formed between the first side plate 40 and the second side plate 50 .

[0056] The cigarettes can be supported by the support plate 30 , and the conveying channel 10 can be limited by the first side plate 40 and the second side plate 50 , thereby ensuring the smooth conveyance of the cigarettes.

[0057] like Figure 4 As shown, the first side plate 40 includes a first plate portion 41 and a second plate portion 42, the second side plate 50 includes a third plate portion 51 and a fourth plate portion 52, a first conveying section 11 is formed between the first plate portion 41 and the third plate portion 51, and a second conveying section 12 and a third conveying section 13 are formed between the second plate portion 42 and the fourth plate portion 52.

[0058] The first plate portion 41 and the third plate portion 51 are vertically arranged flat plates, and the second plate portion 42 and the fourth plate portion 52 are substantially C-shaped bent plates.

[0059] The first side plate 40 and the second side plate 50 are arranged opposite to each other. In the second conveying section 12, the distance between the first side plate 40 and the second side plate 50 gradually increases in the direction away from the first conveying section 11 and then remains unchanged. In the third conveying section 13, the distance between the first side plate 40 and the second side plate 50 gradually decreases in the direction away from the first conveying section 11.

[0060] In the first channel 121, the first side plate 40 is parallel to the first inclined surface on the outside of the diverter block 22; in the second channel 122, the second side plate 50 is parallel to the second inclined surface on the outside of the diverter block 22. This arrangement helps to keep the cigarettes neat during transportation.

[0061] In some embodiments, the sum of the flow rate of the first channel 121 and the flow rate of the second channel 122 is substantially equal to the flow rate of the first conveying section 11. This arrangement can avoid the layer movement of cigarettes during the conveying process as much as possible, and keep the cigarettes conveyed smoothly as much as possible.

[0062] In some embodiments, the flow rate of the first channel 121 is equal to the flow rate of the second channel 122. In this way, uniform flow distribution can be achieved.

[0063] In some embodiments, the cigarette conveying device further includes a fixing block 60 , which is connected between the first side plate 40 and the support plate 30 and between the second side plate 50 and the support plate 30 .

[0064] By setting the fixing block 60, the connection stability between the first side plate 40 and the support plate 30 and between the second side plate 50 and the support plate 30 can be further improved, thereby preventing the first side plate 40 and the second side plate 50 from moving relative to the support plate 30 and affecting the conveying effect.

[0065] like Figure 4 As shown, the fixing block 60 includes a first fixing block 61, a second fixing block 62, a third fixing block 63 and a fourth fixing block 64, the first side panel 40 is reinforced and connected by the first fixing block 61 and the third fixing block 63, and the second side panel 50 is reinforced and connected by the second fixing block 62 and the fourth fixing block 64.

[0066] In some embodiments, the delivery channel 10 is arranged vertically, and the first channel 121 and the second channel 122 are arranged obliquely relative to the vertical direction, so that the cigarettes can move and flow under the action of gravity, reducing the requirements for delivery power.

[0067] like Figure 1 As shown, the cigarette conveying device further includes a flow limiting device 70, which is disposed downstream of the third conveying section 13, and is used for conveying the cigarettes in an orderly manner.

[0068] The flow limiting device 70 includes at least two conveying passages, each of which allows one cigarette to pass through, so that the cigarettes can enter the conveying passages in sequence and be output in sequence.

[0069] The conveying paths in the flow limiting device 70 gradually approach each other in a direction away from the third conveying section 13 , so as to reduce the gaps between the cigarettes at the output end of the flow limiting device 70 .

[0070] The cigarette conveying device provided by the present invention has a simple structure, is easy to use, and has strong practicality. It plays a good role in diverting and conveying cigarettes in the high-level conveying channel, solves the problem of squeezing caused by the gravity of the upper cigarettes, and effectively reduces the quality problems such as cigarette contacts, cigarette flattening, and cigarette wrinkles caused in the process of cigarette diversion and conveying, which is beneficial to improving the stability of equipment operation and product quality.

[0071] Based on the above-mentioned cigarette conveying device, the present invention also proposes a cigarette packaging machine, which includes the above-mentioned cigarette conveying device.

[0072] The positive technical effects of the cigarette conveying device in the above-mentioned embodiments are also applicable to the cigarette packaging machine and will not be described in detail here.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that without departing from the principles of the present invention, the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents, and these modifications and equivalent replacements should be included in the scope of the technical solution for protection of the present invention.
