Description

Technical Field

[0001] This invention relates to the field of cigarette conveying technology, and particularly to a cigarette conveying and protection device for packaging machines and its usage. Background Technology

[0002] The YB615 carton packaging machine is a packaging machine used for packaging cigarette packs. During the packaging process, the pusher plate in the YB615 first pushes the cigarette layers (a stack of five packs each from the first and second layers) supplied by the upstream machine to the middle of the pre-glued and undone carton paper. A series of folders in the YB615 then fold the carton paper containing the cigarette packs, forming the first carton containing 10 packs of "two-five flat packs". At this point, the pusher plate in the YB615 then pushes the first carton... The cigarettes are pushed into the cigarette conveying channel. This process of layering cigarettes, folding cartons, and pushing cigarettes is repeated. The first carton of cigarettes is then pushed by the second, third, fourth, and so on, through the cigarette output channel to the cigarette inspection and rejection station downstream of the cigarette output channel. The cigarette inspection and rejection station inspects the passing cigarettes. If the cigarettes fail the inspection, they are removed from the cigarette conveying channel. If the cigarettes pass the inspection, they are transported to the next cigarette packing station via another conveying channel connected to the cigarette output channel for subsequent packing operations.

[0003] As the cigarette packs travel downstream from the cigarette pack outlet to the cigarette pack inspection and rejection station, and the station rejects the defective cigarette packs, the glue on the outer shell (pack: carton) of the newly packaged cigarette packs has not yet dried. After the defective cigarette packs are rejected at the inspection and rejection station, another cigarette pack located behind the defective one and inside the cigarette pack outlet cannot come into contact with the rejected cigarette pack for protection. The outer shell of the other cigarette pack remaining in the cigarette pack conveying channel will spread out due to the excessive conveying speed. The spread-out cigarette packs will then get stuck in the cigarette pack conveying channel, indirectly causing a blockage in the cigarette pack conveying channel. This not only seriously affects the high efficiency of the equipment, but also generates some waste cigarette packs due to the spread-out cigarette packs, indirectly causing a waste of raw materials such as carton paper.

[0004] Therefore, it is necessary to install a structure to protect the cigarette packs at the cigarette pack outlet. This is to address the issue that after the unqualified cigarette packs are removed at the cigarette pack inspection and rejection station downstream of the cigarette pack outlet, another cigarette pack located behind the unqualified cigarette pack and inside the cigarette pack outlet cannot come into contact with and protect it. As a result, the outer shell of the other cigarette pack remaining in the cigarette pack conveying channel will disperse due to the excessive conveying speed. The dispersed cigarette packs will then get stuck in the cigarette pack conveying channel, indirectly causing a blockage. This not only seriously affects the high efficiency of the equipment but also generates some waste cigarette packs due to the dispersion of the cigarette packs, indirectly causing a waste of raw materials for the cigarette pack packaging. Summary of the Invention

[0005] The purpose of this invention is to propose a cigarette protection device for conveying cigarette packs in a packaging machine. Since another cigarette pack located after the defective cigarette pack and inside the cigarette pack outlet cannot come into contact with and be protected by the rejected cigarette pack, the outer shell of the other cigarette pack remaining in the cigarette pack conveying channel will disperse due to the excessive conveying speed. The dispersed cigarette pack will then get stuck in the cigarette pack conveying channel, indirectly causing a problem of cigarette blockage in the cigarette pack conveying channel.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0012] Preferably, the support includes a first connecting seat and a first connecting rod; the first connecting seats are respectively connected to the first feeding guide plate near the cigarette outlet, and the first connecting rod is connected between the two first connecting seats. The through holes on each swing bar are respectively rotatably connected to the first connecting rod, and each swing bar is arranged at intervals along the first connecting rod.

[0013] Preferably, the elastic element is a spring, with the first end of each spring connected to the first end of each swing bar, the second end of each spring connected to the top of the first feeding guide plate, and each spring arranged at intervals along the top of the first feeding guide plate.

[0014] Preferably, the packaging machine cigarette conveying and smoke protection device further includes a limiting component, which is a limiting gate. The limiting gate is mounted on the top of the first feeding guide plate. Directly below the limiting gate are multiple spaced swing bars, each swing bar moving and limitingly contacting the top of the limiting gate.

[0015] Preferably, the adjusting component includes a first adjusting unit and a second adjusting unit; the first adjusting unit is respectively connected to the first side wall of the first feeding guide plate and the first side wall of the second feeding guide plate, the first adjusting unit, the first side wall of the first feeding guide plate and the first side wall of the second feeding guide plate are all located on the same side, the second adjusting unit, the second side wall of the first feeding guide plate and the second side wall of the second feeding guide plate are all located on the same side, and the second adjusting unit is connected to the second side wall of the first feeding guide plate and the second side wall of the second feeding guide plate.

[0016] Preferably, the first adjustment unit includes a first connecting block, a first adjusting sleeve, a second connecting block, a first adjusting rod, and a first adjusting pin; the first connecting block is connected to the first side wall of the first feeding guide plate, the second connecting block is connected to the first side wall of the second feeding guide plate, the first adjusting sleeve is connected to the second connecting block, the first adjusting sleeve is tunably connected to the first adjusting rod inside the first adjusting sleeve through the first adjusting pin, the first end of the first adjusting rod is slidably adapted to the inside of the first adjusting sleeve, and the second end of the first adjusting rod is connected to the first connecting block.

[0018] This application discloses a method for using a cigarette conveying and smoke protection device in a packaging machine, comprising the following steps:

[0019] If the cigarette pack is delivered to the cigarette pack outlet, the driving end of the contact component at the cigarette pack outlet will be pushed by the delivered cigarette pack and rotate slightly upward around the support component;

[0020] When the driving end of the contact element rotates slightly upward, it rotates slightly downward, thereby compressing and deforming the elastic element connected to the contact element (driving end).

[0021] Under the elastic force generated by the elastic element connected to the driving end of the contact element to restore its deformation, the contact end of the contact element generates frictional resistance with the top of the cigarette pack at the cigarette pack outlet to protect the cigarette pack. This prevents the situation where the outer shell of the cigarette pack located after the rejected cigarette pack and at the cigarette pack outlet is not firmly bonded and is not dispersed due to the resistance of the rejected cigarette pack after the previous cigarette pack has been rejected by the cigarette pack detection and rejection station downstream of the cigarette pack outlet.

[0022] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0023] This invention provides a cigarette conveying and protective component at the cigarette pack outlet. When the cigarette pack is conveyed to the outlet, the contact end of the contact component at the outlet is first pushed upwards slightly around the support component by the cigarette pack. This indirectly compresses and deforms the elastic component connected to the drive end of the contact component. Then, under the elastic force of the elastic component recovering its deformation, the contact end of the contact component comes into contact with the cigarette pack at the outlet, generating friction to protect the cigarette pack. In other words, the cigarette pack at the outlet is resisted by the contact component. Under the action of the contact component, the overall shape and tension of the cigarette pack shell (cigarette pack shell: carton) are restricted, thereby causing the cigarette pack shell to bond towards the side wall bonding area. This design ensures a more secure bond, preventing situations where, after a pack of cigarettes is rejected by the downstream cigarette inspection station, the loosely bonded outer shell of the cigarette pack located at the cigarette exit point is not resisted and thus falls apart. It also ensures stable cigarette transport, guaranteeing the stability of the cigarette transport process. Since another cigarette pack located after the rejected pack and within the cigarette exit point cannot contact and protect itself from the rejected pack, the outer shell of the remaining cigarette pack in the transport channel will fall apart due to excessive transport speed. This falling cigarette pack will then become stuck in the transport channel, indirectly causing a blockage. Attached Figure Description

Detailed Implementation

[0032] like Figure 1-7 As shown, to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0033] Example

[0034] As the cigarette packs travel downstream from the cigarette pack outlet to the cigarette pack inspection and rejection station, and the station rejects the defective cigarette packs, the glue on the outer shell (pack: carton) of the newly packaged cigarette packs has not yet dried. After the defective cigarette packs are rejected at the inspection and rejection station, another cigarette pack located behind the defective one and inside the cigarette pack outlet cannot come into contact with it. As a result, the outer shell of the other cigarette pack remaining in the cigarette pack conveying channel will separate, and the separated cigarette pack will get stuck in the conveying channel, indirectly causing a blockage. This not only seriously affects the high efficiency of the equipment, but also generates some waste cigarette packs due to the separation of the cigarette packs, indirectly causing a waste of raw materials such as carton paper. Therefore, this application proposes a cigarette conveying and protection device for a packaging machine to solve the problem that after unqualified cigarettes are removed at the cigarette inspection and rejection station downstream of the cigarette outlet, the outer shell of another cigarette left in the cigarette conveying channel will spread out, and the spread cigarettes will get stuck in the cigarette conveying channel, indirectly causing the cigarette conveying channel to be blocked.

[0035] For details, please refer to Figure 1This application proposes a cigarette conveying and smoke protection device for a packaging machine in its first aspect. The device includes a first feeding guide plate 1, a second feeding guide plate 2, and a cigarette conveying and smoke protection component 9. The first feeding guide plate 1 is adjustablely connected to the second feeding guide plate 2 via adjusting components 3. A cigarette conveying area 4 is defined between the first feeding guide plate 1 and the second feeding guide plate 2. A cigarette inlet 5 is defined between the first end of the first feeding guide plate 1 and the first end of the second feeding guide plate 2. A cigarette outlet 6 is defined between the second end of the first feeding guide plate 1 and the second end of the second feeding guide plate 2. The cigarette outlet 6, the cigarette conveying area 4, and the cigarette inlet 5 are sequentially connected. A connecting element is provided on the first feeding guide plate 1 at the cigarette outlet 6. The gap 7 of the cigarette conveying area 4 is interconnected, and the gap 7 on the first feeding guide plate 1 corresponds to the extension area 8 of the second feeding guide plate 2; the cigarette conveying and protective component 9 includes abutting component 10, supporting component 11 and elastic component 12; the fixed end of the supporting component 11 is connected to the top of the first feeding guide plate 1 near the cigarette outlet 6, each abutting component 10 is arranged at intervals along the supporting component 11, each abutting component 10 is rotatably connected to the supporting component 11, the abutting end of each abutting component 10 extends from the gap 7 on the first feeding guide plate 1 to the inside of the cigarette outlet 6, the driving end of each abutting component 10 is connected to the first end of each elastic component 12, and the second end of each elastic component 12 is connected to the top of the first feeding guide plate 1.

[0036] In practical applications, when conveying cigarette packs using this conveying channel, the conveying distance (conveyoring distance: the area for conveying cigarette packs) between the first feeding guide plate 1 and the second feeding guide plate 2 is adjusted to match the height of the cigarette packs being conveyed, based on the height of the cigarette packs being conveyed. (The distance matching the height of the cigarette packs is: the top of the cigarette pack slides into contact with the top of the first feeding guide plate, and the bottom of the cigarette pack makes dynamic contact with the bottom of the second feeding guide plate 2. Under this premise, the cigarette packs can still be smoothly conveyed within the conveying area defined between the first feeding guide plate 1 and the second feeding guide plate 2.) Then, through... The pusher plate in the YB615 carton paper packaging machine pushes the packaged first carton of cigarettes into the cigarette conveying channel defined by the first feeding guide plate 1 and the second feeding guide plate 2. Once the first carton of cigarettes has entered the cigarette conveying channel from the inlet, the pusher plate further pushes the packaged second carton of cigarettes into the cigarette conveying channel already containing the first carton. The first carton of cigarettes continues to move towards the cigarette outlet due to the push from the second carton. This process, using the pusher plate in the YB615 carton paper packaging machine, pushes the cigarettes into the channel pre-loaded with the first carton of cigarettes. The process of conveying the first, second, and subsequent cartons of cigarettes through the cigarette conveying channel is repeated. The first, second, and subsequent cartons of cigarettes are pushed through the conveying channel and pass through the cigarette outlet 6. Simultaneously, the contact end of the contact member 10 at the cigarette outlet is pushed upwards slightly around the support member 11 by the incoming cigarettes, indirectly compressing the elastic member 12 connected to the driving end of the contact member 10. Under the elastic force of the elastic member 12 recovering its deformation due to compression, the contact end of the contact member 10 contacts the cigarettes at the cigarette outlet 6, generating frictional resistance. Protecting the cigarette pack means that the cigarette pack at the cigarette pack outlet comes into contact with the contacting member 10. Under the contacting action of the contacting member 10, the overall shape and tension of the cigarette pack outer shell (cigarette pack outer shell: pack box) are restricted and solidified, which makes the cigarette pack outer shell bond more firmly towards the side wall bonding area. This not only prevents the situation where the outer shell of the cigarette pack located after the rejected cigarette pack and at the cigarette pack outlet is not firmly bonded and is not dispersed due to the contact of the rejected cigarette pack after the previous cigarette pack at the cigarette pack outlet is rejected by the cigarette pack inspection and rejection station downstream of the cigarette pack outlet, but also ensures the stability of the cigarette pack transportation.

[0037] During the process of conveying the cigarette packs through the conveying channel, the top of the cigarette pack slides in contact with the inner wall of the first feeding guide plate 1, and the bottom of the cigarette pack slides in contact with the inner wall of the second feeding guide plate 2. Thus, the cigarette pack conveying area defined between the first feeding guide plate 1 and the second feeding guide plate 2 provides the first constraint on the cigarette pack outer shell. During this period, the tension at the bonding joint of the cigarette pack outer shell is low, indirectly making the loosely bonded areas of the cigarette pack outer shell more firmly bonded. This is the first reinforcement of the loosely bonded areas of the cigarette pack outer shell. Then, the cigarette packs, after the first reinforcement, undergo a second reinforcement at the bonding joints of the side walls through the pushing and contact of the two cigarette packs in front and behind. Finally, after the second reinforcement... The cigarette pack then comes into contact with the outer wall of the cigarette pack via the contact element 10 at the cigarette pack outlet, thus imposing a second restriction on the cigarette pack shell. During this time, the tension at the bonding joint of the cigarette pack shell is low, further strengthening the bonding strength at the bonding joint. After this reinforcement of the bonding joint of the cigarette pack shell three times, the bonding joint on the side wall of the cigarette pack shell will not easily come apart. Since another cigarette pack located after the defective cigarette pack and inside the cigarette pack outlet cannot come into contact with the rejected cigarette pack for protection, the outer shell of the other cigarette pack remaining in the cigarette pack conveying channel will come apart due to the excessive conveying speed. The separated cigarette pack will then be stuck in the cigarette pack conveying channel, indirectly causing a problem of cigarette blockage in the cigarette pack conveying channel.

[0038] It should be noted that, in order to improve the bonding strength of the cigarette pack outer shell, a hot air assembly is also installed between the cigarette pack outlet 6 and the cigarette pack inspection and rejection station. The blowing end of the hot air assembly faces the side wall of the cigarette pack at the cigarette pack outlet (the side wall of the cigarette pack: the bonding area of ​​the cigarette pack outer shell). The hot air assembly includes a bracket fixedly connected to the ground, and a hot air fan is installed on the bracket. The blowing end of the hot air fan faces the bonding area of ​​the cigarette pack outer shell. When a cigarette pack is rejected by the cigarette pack inspection station and is abutted by the abutting part at the cigarette pack outlet, the hot air fan is turned on and blows hot air onto the bonding area of ​​the cigarette pack outer shell. The hot air blown out will dry the bonding area of ​​the cigarette pack outer shell again, so that the bonding area of ​​the cigarette pack outer shell is more firmly bonded. The air blown out by the hot air fan only dries the bonding area of ​​the cigarette pack outer shell and will not blow the cigarette pack around. In order to dry the different bonding areas of the cigarette pack shell, multiple hot air components can be arranged between the cigarette pack outlet and the cigarette pack inspection and rejection station, with the blowing end of each hot air component facing the different bonding areas of the cigarette pack shell.

[0039] It should be noted that, to further improve the bonding strength of the cigarette pack outer shell, a pressing component for reinforcing the bonding area may be provided between the cigarette pack outlet 6 and the cigarette pack inspection and rejection station. This pressing component includes servo motors, which are fixedly mounted on the conveyor support between the cigarette pack outlet 6 and the cigarette pack inspection and rejection station. Each servo motor is close to the cigarette pack outlet 6 and located downstream of the contact component 10. The output shaft of each servo motor is connected to the side wall of a rectangular pressing plate. Part of the pressing plate extends into the conveying area between the cigarette pack outlet 6 and the cigarette pack inspection and rejection station. Each pressing plate is attached to a different part of the bonding area between the cigarette pack outer shell. The pressing mechanism works in conjunction with the cigarette pack's positioning. When the cigarette pack is conveyed to the cigarette pack outlet 6 and is pressed by the contacting part 10, and the cigarette pack is rejected by the previous cigarette pack, the servo motor can be driven to rotate the pressing plate, which is pre-positioned outside the cigarette pack conveying area, by a certain angle. This causes the pressing plate to rotate into the cigarette pack conveying area and press against different parts of the cigarette pack's bonding area, making the bonding of the cigarette pack more secure. When the two pressing plates press against the bonding area of ​​the cigarette pack's outer shell, there will be no interference, that is, the two pressing plates will not overlap, and there will be a certain gap between the two pressing plates. After the pressing plate presses against the bonding area of ​​the cigarette pack's outer shell, the servo motor is driven to rotate the pressing plate out of the cigarette pack conveying area, and the cigarette pack continues to be conveyed normally.

[0040] Please see Figure 2 The contact element 10 for contacting the cigarette pack includes a swing bar 13 and an arc-shaped contact bar 14. The through hole 15 on the swing bar 13 is rotatably connected to the support member 11. The first end of the swing bar 13 away from the cigarette pack outlet 6 is connected to the first end of the elastic member 12. The second end of the swing bar 13 is connected to the first end of the arc-shaped contact bar 14. The second end of the arc-shaped contact bar 14 extends from the notch 7 on the first feeding guide plate 1 into the cigarette pack outlet 6. The arc-shaped protrusion of the arc-shaped contact bar 14 contacts the cigarette pack in the cigarette pack conveying area 4.

[0041] In practical application, during the process of the contacting member 10 contacting the cigarette pack, the swinging bar 13 in the contacting member 10 will rotate around the support member 11 under the elastic action of the elastic member 12 and rise vertically. At the same time, the arc-shaped contacting bar 14 connected to the swinging bar 13 will move downward in the vertical direction to contact the cigarette pack at the cigarette pack outlet.

[0042] It should be noted that, in order to prevent the outer wall of the arc-shaped protrusion from rigidly contacting the cigarette pack, the arc-shaped protrusion is polished, that is, the arc-shaped protrusion that contacts the cigarette pack is smoothly designed.

[0043] Please see Figure 3During the upward rotation of the swing bar 13, the swing bar 13 support member 11, which is rotatably connected to the swing bar 13, includes a first connecting seat 16 and a first connecting rod 17. The first connecting seats 16 are respectively connected to the first feeding guide plate 1 near the cigarette outlet 6, and the first connecting rod 17 is connected between the two first connecting seats 16. The through holes 15 on each swing bar 13 are rotatably connected to the first connecting rod 17, and each swing bar 13 is arranged at intervals along the first connecting rod 17.

[0044] In practical application, during the process of the arc-shaped contact strip 14 contacting the cigarette pack, the elastic element 12 will drive the swing strip 13 to rise upward around the first connecting rod 17 under the action of elastic force. At the same time, the arc-shaped contact strip 14 connected to the swing strip 13 moves downward and contacts the cigarette pack at the cigarette pack outlet. During this process, the first connecting rod 17 in the support member 11 serves as the pivot point around which the swing strip 13 drives the arc-shaped contact strip 14 to rotate.

[0045] Please see Figure 1 The elastic element 12 used to drive the swing bar 13 to rise vertically and indirectly drive the arc-shaped abutment bar 14 connected to the swing bar 13 to press down vertically (the arc-shaped abutment bar 14 presses down vertically: the arc-shaped abutment bar 14 moves down toward the top of the cigarette in the vertical direction) is a spring. The first end of each spring is connected to the first end of each swing bar 13, and the second end of each spring is connected to the top of the first feeding guide plate 1. Each spring is arranged at intervals along the top of the first feeding guide plate 1.

[0046] In practical application, during the process of the arc-shaped abutting bar 14 connected to the swing bar 13 abutting the cigarette at the cigarette outlet, the swing bar 13 will be lifted upward in the vertical direction under the elastic force of the spring restoring its deformation, while the arc-shaped abutting bar 14 connected to the swing bar 13 and close to the cigarette outlet will be pressed down in the vertical direction to abut the cigarette at the cigarette outlet.

[0047] Please see Figure 3 To prevent the arc-shaped contact strip 14 connected to the swing strip 13 from pressing too tightly against the cigarette at the cigarette outlet, a cigarette conveying and smoke protection device for a packaging machine also includes a limiting member 18. The limiting member 18 is a limiting gate, which is mounted and connected to the top of the first feeding guide plate 1. Directly below the limiting gate are multiple swing strips 13 arranged at intervals, and each swing strip 13 is in movable contact with the top of the limiting gate for limitation.

[0048] In practical applications, during the contact process between the arc-shaped contact strip 14 connected to the swing strip 13 and the cigarette, since a limiting gantry is provided directly above the swing strip 13, the swing strip 13, which is raised towards the limiting gantry under the action of the elastic element 12 (elastic element: spring), is blocked by the limiting gantry to prevent the swing strip 13 from continuing to rise in the vertical direction, thereby indirectly causing the arc-shaped contact strip 14 connected to the swing strip 13 to continue to move down in the vertical direction and tightly contact the cigarette at the cigarette outlet.

[0049] It should be noted that the swing bar 13 is in actuated limit against the top of the limiting gantry. That is, when the swing bar 13 is pressed towards the spring, the swing bar 13 does not abut against the bottom of the limiting gantry; when the swing bar 13 is not pressed, the swing bar 13 abuts against the bottom of the limiting gantry under the force of the spring's restoring deformation.

[0050] It should be noted that, in order to avoid rigid contact between the swing bar 13 and the top of the limiting gantry, a rubber pad is also attached to the top of the limiting gantry.

[0051] Please see Figure 4 The adjusting component 3 for adjusting the distance between the first feeding guide plate 1 and the second feeding guide plate 2 includes a first adjusting unit 19 and a second adjusting unit 20. The first adjusting unit 19 is connected to the first side wall of the first feeding guide plate 1 and the first side wall of the second feeding guide plate 2 respectively. The first adjusting unit 19, the first side wall of the first feeding guide plate 1 and the first side wall of the second feeding guide plate 2 are all located on the same side. The second adjusting unit 20, the second side wall of the first feeding guide plate 1 and the second side wall of the second feeding guide plate 2 are all located on the same side. The second adjusting unit 20 is connected to the second side wall of the first feeding guide plate 1 and the second side wall of the second feeding guide plate 2.

[0052] In practical applications, when adjusting the distance between the first feeding guide plate 1 and the second feeding guide plate 2 using the first adjusting unit 1 and the second adjusting unit 20 in the adjusting component 3, that is, when adjusting the conveying area 4 of the cigarette conveying channel, the first adjusting unit 19 and the second adjusting unit 29 can be adjusted simultaneously according to the height specifications of the cigarettes, so that the distance between the first feeding guide plate 1 and the second feeding guide plate 2 increases or decreases, thereby adjusting the conveying area 4 of the cigarette conveying channel to a sliding contact height that matches the conveying of the cigarettes (sliding contact height: the top of the cigarette slides into contact with the inner top wall of the conveying area 4, and the bottom of the cigarette slides into contact with the inner top wall of the conveying area 4). 4. The inner bottom wall slides in contact, that is, the top of the cigarette pack slides in contact with the inner wall of the first feeding guide plate 2, and the bottom of the cigarette pack slides in contact with the inner wall of the second feeding guide plate 2. In this way, the cigarette pack conveying channel can not only adapt to conveying cigarette packs of different heights, but also restrict and solidify the outer shell of the cigarette packs entering the cigarette pack conveying channel, thereby consolidating the glue bonding of the outer shell of the cigarette packs and making the bonding of the outer shell of the cigarette packs more firm. This avoids the situation where the bonding of the outer shell side wall of the remaining cigarette pack at the cigarette pack outlet is not resisted after the unqualified cigarette packs are rejected at the cigarette pack inspection and rejection station downstream of the cigarette pack outlet.

[0053] Please see Figure 5 The first adjustment unit 19, used in conjunction with the second adjustment unit 20 to adjust the distance between the first feeding guide plate 1 and the second feeding guide plate 2, includes a first connecting block 21, a first adjusting sleeve 22, a second connecting block 23, a first adjusting rod 24, and a first adjusting pin 25. The first connecting block 21 is connected to the first side wall of the first feeding guide plate 1, and the second connecting block 23 is connected to the first side wall of the second feeding guide plate 2. The first adjusting sleeve 22 is connected to the second connecting block 23. The first adjusting sleeve 22 is tunably connected to the first adjusting rod 24 inside the first adjusting sleeve 22 through the first adjusting pin 25. The first end of the first adjusting rod 24 is slidably adapted to the inside of the first adjusting sleeve 22, and the second end of the first adjusting rod 24 is connected to the first connecting block 21.

[0054] In practical application, while the second adjustment unit 20 adjusts the distance between the first feeding guide plate 1 and the second feeding guide plate 2, the first adjustment pin 25 can be pulled out from the first adjustment sleeve 22 and the first adjustment rod 24, so that the first adjustment rod 24 and the first adjustment sleeve 22 are in an active state. Then, the first adjustment rod 24 is moved up or down along the first adjustment sleeve 22 in the vertical direction to the corresponding position and stops. Then, the first adjustment pin 25 is simultaneously inserted into the first adjustment rod 24 and the first adjustment sleeve 22, which indirectly and temporarily locks the distance between the first feeding guide plate 1 and the second feeding guide plate 2 in the adjusted position, so as to coordinate with the second adjustment unit 20 to adjust the distance between the first feeding guide plate 1 and the second feeding guide plate 2.

[0055] It should be noted that the first adjusting sleeve 22 is tunably connected to the first adjusting rod 24 inside the first adjusting sleeve 22 via the first adjusting pin 25. That is, the first adjusting sleeve 22 has a through first pin hole, and the first adjusting rod 24 has a through second pin hole. Several second pin holes are spaced apart along the first adjusting rod 24. The first adjusting pin 25 is inserted into the second pin hole on the first adjusting rod 24 and the first pin hole on the first adjusting sleeve 22 to realize the function of tunably connecting the first adjusting sleeve 22 to the first adjusting rod 24 inside the first adjusting sleeve 22 via the first adjusting pin 25.

[0056] It should be noted that multiple first adjustment units 19 may be provided at intervals along the first side wall of the first feeding guide plate 1 and the first side wall of the second feeding guide plate 2.

[0057] Please see Figure 6 The second adjustment unit 20, used to adjust the distance between the first feeding guide plate 1 and the second feeding guide plate 2 in conjunction with the first adjustment rod 24 in the first adjustment unit 19, includes a third connecting block 30, a second adjustment sleeve 26, a fourth connecting block 27, a second adjustment rod 28, and a second adjustment pin 29. The third connecting block 30 is connected to the second side wall of the first feeding guide plate 1, and the fourth connecting block 27 is connected to the second side wall of the second feeding guide plate 2. The second adjustment sleeve 26 is connected to the fourth connecting block 27. The second adjustment sleeve 26 is tunably connected to the second adjustment rod 28 inside the second adjustment sleeve 26 through the second adjustment pin 29. The first end of the second adjustment rod 28 is slidably adapted to the second adjustment sleeve 26, and the second end of the second adjustment rod 28 is connected to the third connecting block 30.

[0058] In practical application, while the first adjusting unit 19 adjusts the distance between the first feeding guide plate 1 and the second feeding guide plate 2, the second adjusting pin 29 can be pulled out from the second adjusting sleeve 26 and the second adjusting rod 28, so that the second adjusting rod 28 and the second adjusting sleeve 26 are in an active state. Then, the second adjusting rod 28 is moved up or down along the second adjusting sleeve 26 in the vertical direction to the corresponding position and stops. Then, the second adjusting pin 29 is simultaneously inserted into the second adjusting rod 28 and the second adjusting sleeve 26, indirectly locking the distance between the first feeding guide plate 1 and the second feeding guide plate 2 in the adjusted position, so as to coordinate with the first adjusting unit 19 to adjust the distance between the first feeding guide plate 1 and the second feeding guide plate 2.

[0059] It should be noted that the second adjusting sleeve 26 is tunably connected to the second adjusting rod 28 inside the second adjusting sleeve 26 via the second adjusting pin 29. That is, the second adjusting sleeve 26 has a through first pin hole, and the second adjusting rod 28 has a through second pin hole. Several second pin holes are spaced apart along the second adjusting rod 28. The second adjusting pin 29 is inserted into the second pin hole on the second adjusting rod 28 and the first pin hole on the second adjusting sleeve 26 to realize the function of tunably connecting the second adjusting sleeve 26 to the second adjusting rod 28 inside the second adjusting sleeve 26 via the second adjusting pin 29.

[0060] It should be noted that multiple second adjustment units 20 may be provided at intervals along the second side wall of the first feeding guide plate 1 and the second side wall of the second feeding guide plate 2.

[0061] This application discloses a method of using a cigarette conveying and smoke protection device for a packaging machine in a second aspect. The method of using the cigarette conveying and smoke protection device for a packaging machine includes the following steps:

[0062] If the cigarette pack is delivered to the cigarette pack outlet 6, the driving end of the contact member 10 at the cigarette pack outlet 6 will be pushed by the delivered cigarette pack and rotate slightly upward around the support member 11.

[0063] When the driving end of the contact member 10 rotates slightly upward, the driving end of the contact member 10 rotates slightly downward, thereby causing the elastic member 12 connected to the driving end of the contact member 10 to be compressed and deformed.

[0064] Under the elastic force generated by the elastic member 12 connected to the driving end of the contact member 10 to restore its deformation, the contact end of the contact member 10 generates frictional resistance with the top of the cigarette at the cigarette outlet 6 to protect the cigarette and ensure stable delivery of the cigarette.

[0065] If the cigarette pack is delivered to the cigarette pack outlet 6, the driving end of the contact member 10 at the cigarette pack outlet 6 will be pushed by the delivered cigarette pack and rotate slightly upward around the support member 11. As the driving end of the contact member 10 rotates slightly upward, it will also rotate slightly downward, thereby compressing and deforming the elastic member 12 connected to the driving end of the contact member 10. Under the elastic force generated by the elastic member 12 connected to the driving end of the contact member 10 to recover its deformation, the contact end of the contact member 10 will generate frictional resistance with the top of the cigarette pack at the cigarette pack outlet 6 to protect the cigarette pack. This is to prevent the situation where the outer shell of the cigarette pack located after the rejected cigarette pack and at the cigarette pack outlet is not firmly bonded and is not dispersed due to the resistance of the rejected cigarette pack after the previous cigarette pack at the cigarette pack outlet is rejected by the cigarette pack detection and rejection station downstream of the cigarette pack outlet.

[0066] Although the invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter arrangement within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
